When Luo Yi woke up, the whole world changed.

He was holding a bowl to drink the medicine, his face was pale, but there was a pleasant and sincere smile in his eyes.

"Thank you for saving me."

It's completely different from the fake smile before.

Rong Shi suddenly felt uncomfortable, stood up and said, "I didn't save you, Doctor Chen and Doctor Huo saved you."

"But I heard them say that without your drug suppression, I would never have made it to the camp."

Luo Yi put down the medicine bowl slowly, with a relaxed and relaxed expression, as if all the burdens had been lifted at the same time.

"Well, grandpa asked when you will be in the Hui family?" After Rong Shi asked, he thought of something else, "Are you in the Hui family or are you leaving here?"

He remembered that Luo Yi was working for the imperial court, would he go back after finishing the work?

Moreover, Luo Yi saved Princess Ning Xuan, made such a great contribution, His Majesty will definitely reward him, whether it is promotion or wealth, it is impossible for him to stay in this remote village.

Luo Yi shook his head and laughed, "If possible, I want to stay here forever."

"What do you mean?" Rong Shi was puzzled.

Luo Yi didn't answer anymore, but changed the subject, "I heard that all the tribes have surrendered to the imperial court?"

"Well," Rong Shi's eyes lit up immediately, showing admiration, "Duke Dingguo is really too powerful, those tribes can't resist it at all, even the Wuta tribe can't help it."

Luo Yi chuckled, "Wuta clan? They discovered a small iron mine, made iron tools, and tried to rebel against the imperial court and unify the south. It's too naive."

"It's not really naive," Rong Shi sighed, "After we defeated the Wuta clan with the imperial army, we found that they had privately cast a lot of weapons and hid them in caves. If the imperial court did not send troops, or the imperial court did not have elite soldiers Strong generals, none of us are their opponents."

Luo Yi listened quietly, then suddenly laughed, teasingly said: "I found that you talk too much."

Rong Shi's expression changed suddenly, he turned his face away, and said in a muffled voice: "I used to worry that you would hurt the clansmen, so I didn't want to talk to you, I'm sorry."

"I'm not sorry." Luo Yi looked sincere, "Instead, I have to thank you and Patriarch Rong for your tolerance."

Rong Shi coughed lightly, and abruptly changed the subject: "Duke Dingguo and His Royal Highness Princess Chang have returned to Beijing, and I don't know how the court will treat us."

After he and Grandpa decided to submit to the imperial court, they were still a little uneasy.He and his people are like helpless lambs, waiting for the fate to come.

Luo Yi comforted: "It will never be worse than before."

At the beginning of November, Huo Yan led people to subdue the various tribes in the south, and ordered the lieutenant general and thousands of soldiers to stay in Sanzhou, and returned to Beijing with Lou Ling and others to report on their duties.

After a snowfall in the capital, the weather became colder.

After Lou Yu finished his morning court, Ha proceeded to Qinzheng Hall.A charcoal basin was lit in the Hall of Qinzheng, and the interior of the hall was as warm as spring.

"Your Majesty, drink a cup of tea to warm up your body first." Feng Erbi brought the tea at the right time.

Lou Yu gulped down the drink, a stream of heat flowed through the throat into the stomach, and the warmth instantly swept through the four limbs and eight veins.

After warming up, he concentrated on reviewing the memorials.

Under the rectification of the Ministry of Officials, the official documents of the Dasheng government are all concise and concise, which saves Lou Yu's time, and he has approved a lot of papers in a short time.

He opened another one.

This is a memorial written by the prefect of Mengzhou.

When Lou Yu went to the north from the capital, the last gate he passed was the gate of Mengzhou.

At that time, he was only thinking about how to solve the predicament in the north. He didn't pay attention to what Mengzhou City looked like. He only remembered that the posthouse in Mengzhou City was extremely cold, the quilt was extremely hard, and the charcoal burned was not only small, but also smoked heavily.

The content written in this notebook once again brought back his memories.

The memorial was not long, but the words were simple and sincere, which made Lou Yu frown.

He ordered: "Go and ask Mr. Yang and Mr. Fan to come, as well as the Minister of the Ministry of War and the Minister of the Ministry of Finance."

After a while, the four of them gathered in the Hall of Qinzheng, and they all saluted and greeted each other.

Lou Yu asked Feng Erbi to hand them the memorial.

"Look at it all, and tell me what you think after reading it."

After the four of them finished watching, they looked at each other a few times, and Duan Heng, Shangshu of the Ministry of War, came out first.

"Your Majesty, Mengzhou is a border gate of great prosperity, and the climate is indeed bitter and cold. I believe that the memorandum of the magistrate of Mengzhou should not be false."

The memorandum said that the weather this year was worse than previous years, and many people in the countryside of Mengzhou froze to death because they had no firewood to keep warm.Some soldiers in the camp couldn't resist the severe cold, and their hands and feet were frozen.

The magistrate of Mengzhou wrote this memorial in the hope that the court could send some charcoal to the border, at least to ensure the survival of the soldiers at the border.

There is a kang in the north, but it is not enough to have a kang, and firewood or charcoal must be used as a heat source.If there is not enough burning material to keep warm, no matter how many kangs there are, it will be useless.

Lou Yu vaguely remembered that when he went to Mengzhou, he looked across a field and couldn't see a few trees.As a result, it is indeed difficult for the common people to find burning objects.

He couldn't help asking: "Mengzhou lacks forests, how do the people boil water and cook?"

This stopped the four of them.

They never looked into it.

But Fan Yusheng suddenly said: "I don't know about this matter, but I remember that when Huizong was in power, the court also received similar memorials. At that time, in order to ensure the safety of the border, the court allocated a lot of charcoal money to go there."

In other words, this problem in Mengzhou has existed for many years.

"Why is there a lack of trees in the area?" Lou Yu asked again.

Yang Guanghuai replied: "I have read in a local chronicle that there was no shortage of forests in Mengzhou before the previous dynasty, but the court at that time ordered people to cut down the forests and turn them into cultivated land in order to expand reclamation."

In order to fill their stomachs, the people of Mengzhou are desperately cultivating land, and the trees are getting less and less.

The land in Mengzhou is not fertile, and the crops are not harvested well. The worse the crops are, the more the people cultivate, and the more they cultivate, the fewer trees there are. The disappearance of forests intensifies the loss of soil nutrients. Such a vicious circle has become what it is today.

Lou Yu's first reaction was to "return farmland to forests".

But on second thought, Dasheng's current total grain output is not enough to support the people of the whole country to live on food and clothing. If they really want to "return the farmland to forests", the people in Mengzhou will not even have food to eat.

The longer the emperor was, the more difficult it was for him to govern a country.

"The top priority is to avoid more casualties." Lou Yu issued an order, "Lou Shangshu, the Ministry of Finance will allocate an appropriate amount of charcoal funds as soon as possible according to the disaster situation in Mengzhou, so as to ensure the safety of the people and soldiers in Mengzhou."

Lou Quan hesitated and said: "Your Majesty, even if the charcoal funds are allocated, Mengzhou may not be able to buy enough charcoal or firewood."

"Why?"

"In winter, except for the southernmost part, the demand for charcoal in Dasheng is very high, and the price of charcoal is also high. In many places, charcoal is hard to find. Ordinary people can't buy it, and they can't afford it. Even firewood It has also become a hot commodity.”

Some people who rely on the mountain can still pick up some firewood from the mountain to make a fire. In places like Mengzhou, there is no firewood.

Unable to light a fire to keep warm, we can only bear it hard.

Many old and weak people will pass away on cold winter nights because they can't bear it.

Lou Yu was originally a noble man, he never lacked charcoal, he didn't know how difficult the winter was for ordinary people, and when he heard such words suddenly, he couldn't help feeling guilty.

"It's because I haven't thought through enough."

Yang Guanghuai immediately said: "Your Majesty is taking care of all kinds of situations, but I am incompetent if I fail to share your majesty's worries."

The other three also agreed.

They speak the truth.

In their eyes, Lou Yu is a wise king who cares about the common people, but he was born in a wealthy family, how would he know these things?

This matter definitely cannot be blamed on His Majesty.

Lou Yu laughed, and asked Lou Quan: "How did Lou Shangshu know this?"

Lou Quan said: "I heard what others said."

She has many colleagues, some of whom come from poor backgrounds, and she always knows a thing or two.

Lou Yu's eyes fell on the charcoal basin in the hall, where there was silver silk charcoal, which was smokeless and tasteless when burned, and it was specially provided for the nobles to enjoy.

Such a piece of charcoal might be sold for sky-high prices outside.

What a luxury.

He thought for a while and said, "Coal can also be used for heating. I remember that there are coal mines in many prefectures in Dasheng. Can coal be used for heating?"

"Your Majesty, the cost of coal mining is high. Even if it can be sold, ordinary people cannot afford it." Yang Guanghuai said.

There are coal mines in Jizhou. Yang Guanghuai was born in Jizhou, but it is rare for ordinary people to use coal for heating.

On the one hand, coal resources are controlled by the imperial court; on the other hand, coal mining is not easy, and the price is not much cheaper than charcoal.

When Lou Yu could exchange salt and Cheng Da for coal, what could ordinary people exchange for it?

Lou Yu said: "Mining is not easy, and the quantity is small, so the price will naturally not be low."

But this is for lump coal.

Lump coal burns vigorously, has a high calorific value, and burns quickly. It is suitable for kiln smelting, but if it is used by ordinary people, lump coal is not necessarily needed.

If the coal mining technology can be improved and the cost of coal can be reduced, can the common people afford it?

I remember that in modern times, when he was a child, he went back to his hometown in the countryside with his parents and saw briquettes and stoves burning briquettes.

At that time, he was at the age when he had a strong thirst for knowledge, and when he saw novel things, he would catch people and ask them.

Honeycomb coal is made of a mixture of loose coal and loess. Three or four briquettes can be burned for a whole day. It can be used for cooking and boiling water. It is cheap and cost-effective.

Moreover, there are holes in the honeycomb coal, which has a high combustion utilization rate, and it is indeed much more affordable than charcoal or lump coal that cannot be burned.

In the era of advanced science and technology, briquette has gradually withdrawn from the stage of history, but it did bring enough warmth to ordinary people in special times.

But this matter has to be carefully considered. The people and soldiers of Mengzhou are in urgent need of rescue.

"Pass down my will to requisition coal from Jizhou to support Mengzhou."

Jizhou is rich in coal resources. After several years of development, the amount of coal mining has increased year by year. It is no problem to temporarily support Mengzhou for the winter.

"I will obey your orders!"

After several people left the hall, Lou Yu began to think about how to integrate the coal resources of the whole country to produce coal that the common people could afford.

He called Lu You again.

"Mining is under the control of your Ministry of Industry. Do you know anything about coal mining?"

Lu You replied: "As far as I know, most of the coal mines across the country are excavated on the shallow surface with tools such as hand picks, and the deep coal is difficult to mine."

This is also one of the reasons for the low coal production.

"Can't dig a well?" Lou Yu asked.

Lu You sighed: "It is possible to sink a well, but it is very labor-intensive to dig a well. Only some larger coal fields use this technology. Besides, there are often dangers underground."

Lou Yu nodded, the coal mine is indeed dangerous.

He didn't understand mining technology himself, so he had to say: "The order continues, if someone improves the sinking technology and increases the amount of coal mining, the imperial court will definitely reward you."

Under the reward, there must be a brave man.

What Lou Yu needs now is not brave men, but engineers and technicians!

"The minister obeys the order!"

"Your Ministry of Industry has also done a lot of research on mechanical operations. Of course, it is inefficient to rely solely on manpower. You have to use your brain to think about how to replace manpower with machinery. Whoever invents something good will be rewarded heavily by the court."

"The minister obeys the order!"

Lou Yu doesn't know if this reward system can stimulate the vigorous development of the mining industry, but now he can only pin his hopes on the miners.

Talk is better than nothing.

Just when he was worried about the lives of the people, a military report came from the south.

Lou Yu's spirit was shaken, seeing the familiar handwriting on the military newspaper, the boredom of the past few days disappeared, and his eyes showed a little joy.

Although the wording in the military newspaper was serious and serious, Lou Yu still tasted some sweetness from it.

He bowed his head and read carefully.

The first half of the military newspaper talks about the successful rescue of hostages and the surrender of the southern tribes.

Lou Yu was not surprised.

This matter is not a problem for Huo Yan at all.

But the second half of the military newspaper made him raise his eyebrows.

The imperial army discovered iron ore in the Wuta tribe, and the Wuta tribe privately cast iron weapons, which shows their great ambitions.

Pull these people to mine, Lou Yu thought.

He continued to look back, and when he saw that the witch doctor of the Wuta tribe might cure malaria, he raised his eyebrows even higher.

This is an extremely important discovery, and he must figure it out.

If the witch doctors of the Wuta tribe really have the ability to cure malaria patients, then cinchona trees are likely to grow within the Wuta tribe's sphere of influence.

Since the flu in Gyeongju, he has had the caravans keep an eye on the cinchona tree, but unfortunately, there has been no progress over the years.

Could the cinchona tree, which the caravans could not find, be hidden in the mountains of Pingzhou?

When Huo Yan and the others return to Beijing, he must inquire carefully.

Nearly two months away from Beijing, Huo Yan is eager to return home.

He galloped all the way with Lou Ling and others, and finally returned to the capital at the beginning of December.

When I entered Beijing, the capital had the second snow of this winter.

Wrapped in silver, broken jade Qionghua.

The horseshoes left a series of footprints on the snow, and the white slush flew up, each piece revealing the eagerness of the person on the horse.

Liang Pei secretly joked with Lou Ling: "Why do you feel that Duke Ding is more impatient than us?"

Lou Ling frowned slightly, feeling something was wrong in her heart.

Over the past few days, she has learned about Adi's series of actions after he ascended the throne from other people.

While Lou Ling felt proud, he couldn't help but feel regretful.The comments of the Master Ziyun Temple have always made her brood on her heart.

Is this critique really credible?

Lou Ling felt suspicious, and recalled Huo Yan's expression when he first met Huo Yan when he talked about his younger brother.

But Huo Yan had a keen mind and was cautious, so he didn't reveal anything.

"Perhaps you are in a hurry to see your sweetheart." Lou Ling's expression changed, and finally he smiled, "Mr. Ding is only 20 years old now, and he is in full bloom. It's not unusual to have a sweetheart."

Liang Pei nodded, "That's right, Ah Ling still understands."

When the news of Princess Ning Xuanchang's entry into Beijing reached the palace, Lou Yu's heart skipped a beat.

He asked Feng Erbi: "Has the Princess Mansion been taken care of?"

A married princess needs to go out of the palace to build a mansion. As soon as Lou Yu came to the throne, he picked a house with excellent Fengshui for Lou Ling as the princess mansion.

Feng Erbi replied with a smile: "Don't worry, Your Majesty, everything in the Princess Mansion is properly arranged."

"That's good."

Lou Yu couldn't bear to read Zhezi, so he got up and went out of the hall, and stood on the porch looking in the direction of the palace gate.

"Your Majesty, it's cold in the porch, be careful." Feng Erbi put on a cloak for him and advised in a low voice.

He could understand His Majesty's urgent mood, but in his heart, His Majesty's body was the most important.

However, is His Majesty waiting for Princess Ning Xuanchang or Duke Ding?

When Huo Yan came back from the battle, the first thing he did was to enter the palace to meet the Holy Majesty.Lou Ling, Liang Pei and the prefect of Longzhou also had to face the saint to report on their duties.

The snow fell harder.

Lou Yu received a report from the palace people and learned that several people were outside the palace gate, so he immediately returned to the Qinzheng Hall and sat behind the imperial case with a majestic expression.

Feng Erbi: "..."

Your Majesty, you have taken all the memorials upside down.

He reminded in a low voice, Lou Yu coughed lightly, and corrected with red ears.

The heart beat faster and faster, finally, the palace attendant reported outside the palace.

At this time, his heartbeat slowed down, and he said calmly, "Let them in."

In an instant, one person stepped into the hall.

Lou Yu looked up, and a bright and heroic face came into view.

Although he had guessed it long ago, he was still overjoyed when he saw the second sister who was exactly the same.

Their family is finally reunited!

Lou Yu was about to get up to greet him, when another young man entered the hall, with a handsome appearance and a dignified appearance.

It's the son-in-law Liang Pei.

Behind them are Huo Yan and the prefect of Longzhou.

Huo Yan looked straight over with a pair of handsome eyes, deep and quiet, and looked at Lou Yu with horror.

He looked away with difficulty, and his eyes fell on Lou Ling's face.

"My sister was shocked."

Lou Ling hadn't seen Lou Yu for many years, suddenly saw that he had grown into such a regal and noble appearance, couldn't help laughing and crying.

"It was I who worried His Majesty."

Brother is much better than she imagined.

At the right time, Liang Pei and the prefect of Longzhou knelt down to salute.

Lou Yu sighed in his heart, it's a pity that the prefect of Pingzhou was killed by the Wuta clan.

"Get up."

Liang Pei and the prefect of Longzhou still wanted to report on their duties, but they heard Lou Yu say, "Aiqing is on the go all the way, go back and rest first, and we can talk about it tomorrow morning."

Then he said to Lou Ling: "Father, mother and eldest sister are still waiting to see you in Shoukang Palace, you go first, I will discuss state affairs with Dingguo Gong first, and I will go later."

After he said that, the three of Lou Ling had no choice but to leave the hall.

Feng Erbi winked, followed Lou Ling and the others out of the hall, and closed the door intimately.

Lou Ling turned around and looked, feeling even more weird.But she was eager to see her relatives and didn't think much about it.

In Qinzheng Hall, as soon as the door was closed, Lou Yu hugged Huo Yan together.

He buried his face in the man's neck, sniffing the smell of wind and snow all over his body, and whispered: "Ayan, I miss you."

Huo Yan didn't say anything, just pressed the back of his head and kissed him, like a wolf that has been hungry for a long time, vicious and intense.

I miss you so much that my heart aches.

"A Yu, A Yu, A Yu..."

He kissed and called, making Lou Yu's scalp numb, his legs and feet were soft, and his whole heart was soaked in a honey pot, so sweet that his mind went blank.

The next moment, the legs suddenly left the ground.

Huo Yan picked him up and carried him to the soft couch in the inner hall.

"We have to go to Shoukang Palace later." Lou Yu stretched out his hand behind his back to comfort him, "Let's go tonight..."

The lips were blocked again.

After a long time, Lou Yu leaned on the couch, played with Huo Yan's hand, and sighed: "I don't want you to leave Beijing anymore."

The two have been together for so many years, and they have rarely been separated for so long.

Huo Yan hugged him from behind, grabbed his hand and brought it to his lips, kissing him little by little, the sound of the violent heartbeat in his chest was clearly transmitted to Lou Yu through his clothes.

Just a little taste just now can't calm down the heat in Huo Yan's heart at all.

He said in a hoarse voice: "Okay, I will not leave Beijing."

It is very simple to stay in Beijing.

The world is peaceful, Huo Yan can stay in the capital for the rest of his life.

Thinking about it this way, Lou Yu suddenly felt a sense of pride.

He must govern Dasheng well, make Dasheng rich and strong, and no one dares to commit crimes.

The two dawdled for a while, and then went to Shoukang Palace together.

When Lou Ling saw the two of them, he couldn't help showing doubts.

Isn't this a family feast?Why is Ding Guogong here?

The son-in-law Liang Pei immediately bowed to salute.

Lou Yu smiled and said, "This is a family feast, brother-in-law doesn't need to be polite."

In the past, Liang Pei never dared to imagine that his brother-in-law could become the lord of the world. After all, he was lucky not to be demoted.

Along the way, he heard too many stories about Lou Yu, and read many newspapers. His admiration for Lou Yu was like a torrent of water.

His respect comes from the heart.

But seeing Lou Yu's gentle attitude, without the airs of an emperor, he gradually let go, and talked about interesting things about the south with Lou Ling while eating.

As for why Ding Guogong appeared here, he didn't dare to ask.

The family chatted happily.

Lou Ji looked at Lou Ling and Liang Pei in pairs, then looked at Lou Quan and Lou Yu, and couldn't help but drank a few glasses of wine depressedly, and said, "Ah Quan, you are getting old now, when will you find another Ruyi?" Sir?"

"Father, I have no plans to marry yet." Lou Quan said calmly.

She's gotten used to it.

Lou Ji still doesn't know about Lou Yu and Huo Yan. All along, when Huo Yan participated in the family banquet, he thought it was Jiang Lan who wanted to match Huo Yan with his eldest daughter.

Since everyone was present today, he said, "If you two really have the heart, let A Yu marry you."

Crowd: ? ? ?

Jiang Lan pinched him, and Liu Mei frowned slightly: "What are you talking about? What is the marriage? Who is the marriage?"

"For Ah Quan and Ding Guogong." Lou Ji said confidently, "Every time you invite Ding Guogong to come to the family banquet, isn't it because..."

"Don't mess with the mandarin ducks!" Jiang Lan gave him a slight look, "I'm not feeling well, help me to the inner hall. A Yu, eat slowly."

Lou Yu and Huo Yan looked at each other helplessly.

How could his father be so dull?

After the family banquet, Lou Yu took Huo Yan back to the Hall of Mental Cultivation.

Huo Yan still remembered what happened during the dinner, and asked: "Mother said she was not feeling well, but has she seen the imperial doctor?"

"I was going to tell you this." Lou Yu hugged him and blamed himself in a low voice, "Mother is pregnant because of me."

He originally planned to choose an heir from the clan, but he never expected that his mother would take risks for his country.

Huo Yan's arms tightened suddenly, his eyes trembled slightly.

"It is my fault."

It was he who selfishly wanted Lou Yu to be his own.

Lou Yu shook his head: "If it's not good, it belongs to the two of us. Mother thinks about us so much, we can't let her down."

"Okay." Huo Yan kissed the tip of his nose, "No matter what you do, I will stay with you."

Lou Yu's eyes were shining brightly, like falling stars.

"I want to do a lot of things, maybe I can't finish it in my life."

Huo Yan kissed his forehead again, smiling handsomely.

"Then do it one by one, and leave it to the younger generation if you can't finish it, don't tire yourself."

Lou Yu nodded, and said seriously: "What needs to be done most now is to govern the various ethnic groups in the south. The letter is not detailed enough, please tell me in detail what you have seen and heard about this southern expedition."

"it is good."

Lou Yu asked with a smile: "Take a bath first, and then go to the bed to chat?"

Huo Yan's eyes were instantly darkened.

"Together."
