The cannon fodder through the book will live to the end

It was only then that Tao Anran understood what Han Lu meant just now, but looking at their expressions now, he seemed to have said something extraordinary.

Tao Anran nodded hesitantly, "It's possible, but the process is more complicated and there are more things to prepare."

Bai Lu and Han Lu's eyes lit up immediately.The way she looked at Tao Anran changed.It's not the kind of respectful and friendly eyes in the past, but now it seems a little fanatical.

Being stared at by such eyes, Tao Anran felt a little restless.

Seemingly aware of something wrong, Bai Lu recovered quickly, but her voice trembled slightly: "Princess, let's eat something first. It's windy outside, if there is nothing else, let's go back home after dinner."

Tao Anran nodded in agreement. Riding a horse was fun before, but she sweated a little. Now she sat down and felt a bit chilly with the cold wind blowing.

After eating some snacks and pastries, and drinking some hot water, Tao Anran was full.At this time, he also realized that he seemed to have done something extraordinary.He didn't seem to really understand the standard of living here.

Especially when Bai Lu asked the guards around him to dig some salt mines at the foot of the mountain and came back, Tao Anran understood the importance of what he said casually.

On the way back home, Bai Lu in the carriage was busy as usual, but she was a little courteous.More importantly, ask what needs to be prepared to turn the salt mine into edible fine salt.

Tao Anran wanted to do something to change her situation, so she explained in detail some things about making filter equipment.

The carriage rolled back, but the speed was obviously more urgent than when it left the mansion.

In the big tent of the military camp, Xiao Jingyu frowned as he looked at the military account books.Without him, it is too short of money.

Since ancient times, raising soldiers has been a matter that consumes a lot of resources.Although he relied on his status to prevent the imperial court from withholding the food and pay of the Zhenbei Army, it was just a matter of food and clothing on the surface.What he needs far exceeds the food and salaries given by the court.

It also coincides with the start of the winter war, food and grass are only basic, and warm clothes are only enough.Not to mention that once the battle starts, the damaged armor needs to be repaired, and the soldiers who are injured or killed in battle need to be compensated.Every pile of pens needs to be filled with money.

Although Xiao Jingyu specially arranged for some people to do business, and there were some ways to make money, but it was still only enough to barely fill the hole in the military camp.But to reach his goal, these are far from enough.

Xiao Jingyu put down the account book and kneaded the space between his eyebrows.I am glad that my caravan has made a fortune by dumping goods from the north and the south this time, which can make the situation of the soldiers easier.

Suddenly there was a soft sound behind him, and when he turned around, it turned out to be the hidden guard who stayed in the palace.That's why he stayed in the palace to pass the news on purpose.Generally, there is no important matter, and they will not leave their duties lightly.Coming here at this time, could it be that something happened to the palace?

Xiao Jingyu: "What happened?"

The secret guard hastily handed the secret letter in his arms to Xiao Jingyu.

When Xiao Jingyu opened it and looked at the handwriting, he recognized that it was Bai Lu's handwriting that he had deliberately placed next to the princess.He thought a lot for a moment, the biggest possibility is that his princess must have done something to make the secret guard come to deliver the letter so urgently.

Is it because his princess finally couldn't bear to show her flaws and try to harm him?Although Xiao Jingyu didn't trust his princess, if the princess was a little better, he wouldn't mind giving him glory and wealth to support him.But if he had ulterior motives, Xiao Jingyu wouldn't make it easier for him.

Xiao Jingyu turned his mind several times at that moment, and then looked carefully at the secret letter. After reading the entire secret letter, he blinked in disbelief.It is really unbelievable what the letter said.Then he looked it over again.It was indeed what he saw, and he was not mistaken.

Xiao Jingyu's heart was surging, he walked back and forth in the tent for a few steps to stabilize his mood.But in the end he couldn't calm down, and he ordered outside: "Prepare the horse, the king wants to go back to the palace."

Xiao Jingyu hurried all the way back to the palace. This was the first time he returned to the palace after more than ten days.The environment of the palace remained the same, and the face of the housekeeper who came to welcome him remained the same.

"Welcome the prince back home."

"Well, where's the princess?"

Butler Li was a little surprised that the prince asked about the princess's movements as soon as he came back, which was very different from going straight to his yard in the past.But thinking that the prince and concubine are also considered newlyweds, it is normal to miss them after being separated for so many days.

The prince is married too!

Butler Li said with a smile: "The concubine came back an hour earlier, and she is now in the Xueji courtyard. She also took some weird things from the Xueji courtyard. It seems that she is going to do something. As for the specifics, the old slave does not know." gone."

Xiao Jingyu immediately turned around and went to Xueji Courtyard.This was the first time he went to the backyard of the inner house after returning to the palace.As soon as he entered the Xueji Courtyard, he could hear a burst of laughter.There are also some broken words mixed in.

"Princess, it really appeared. It's really salt!"

When Xiao Jingyu heard this, he hurried into the courtyard.The servants in the courtyard are all gathered together at this moment, seeming to point at a clay pot.No one noticed his coming.

Xiao Jingyu was not annoyed either, he walked in to have a look, and saw his princess surrounded by servants turned her back to him and stretched out her hand to take something out of the clay pot, rubbed it with her fingertips, and then stretched out her pink The tip of the tongue licked.

Seeing this scene, Xiao Jingyu's eyes changed.But at this moment, everyone's attention was on the clay pot, and no one noticed.

Tao Anran licked the extracted rock salt, the taste was right, but the particles were still a bit big.He waved his hand, "Go get a mill, let's grind this salt finer."

The maidservants in the yard quickly responded and turned around to get the roller.Turning around, I realized that the prince appeared behind me at some point, but no one noticed.This is their relapse.She broke out in a cold sweat, and quickly knelt down: "See you, my lord!"

At this moment, everyone noticed the prince, so they knelt down in fear, "See the prince!"

Tao An then turned around bewilderedly, only to realize that Xiao Jingyu was right behind him.During this period of time, he was served comfortably, and he didn't have to salute anyone, but he forgot to salute for a while.So at this moment, Tao Anran saw Xiao Jingyu froze for a while before saying, "The lord is back."

Fortunately, Xiao Jingyu's attention was not on this, he just said in a deep voice: "Everyone go down."

Tao Anran blinked, but saved a salute.

Xiao Jingyu focused on the clay pot surrounded by a group of people before.The shallow mouth of the clay pot is not deep, and the mouth of the pot is relatively large. It is a common pottery pot and should be used to put some sundries.It's just that the clay pot is covered with a thick layer of white particles at this time, like snowflakes in winter.

Even though there was already some foreshadowing in his heart, Xiao Jingyu couldn't help being a little excited when he saw this scene.He suppressed the emotions in his heart, looked at the princess on the side, and asked calmly: "Won't the princess explain?"

Tao Anran hadn't seen Xiao Jingyu for some days, but seeing her again now, she felt that this man was still so good-looking.Seeing this, he was a little lost.When he came back to his senses, he realized what Xiao Jingyu seemed to have said just now?

Tao Anran: "Ah! What?"

Xiao Jingyu thought he didn't understand, and asked again patiently, "Princess, can you explain to me what this is?"

Tao Anran saw Xiao Jingyu pointing to the salt in the pot, and immediately understood what he meant. "My lord, this is salt. It is extracted from the rock salt mine outside the city."

Xiao Jingyu continued to ask: "This king has also heard a little about rock salt mines. It is common for some animals to lick the exposed rock salt, but this rock salt cannot be eaten by people, because it is poisonous."

Tao Anran smiled and said: "I know this. In fact, it is enough to filter and decompose the toxic substances in the rock salt mine. The rest is white salt. I guarantee that the extracted salt is not poisonous. And this The salt is still a bit coarse, and it will be ground later to make fine salt more convenient to eat."

Listening to Tao Anran's assurance, Xiao Jingyu was noncommittal.However, he still asked: "Where did the princess learn about this method of turning rock salt into edible salt? And it seems that this king has never seen anyone do it before."

Tao Anran thought about it. When he refined the coarse salt into fine salt, he thought about the problems that would happen later, so he thought of a good excuse.

So, Tao Anran sighed and said, "I came across this method in a strange book by chance."

Xiao Jingyu revealed a curious look at the right time: "Oh? Strange book?"

Tao Anran glanced at his expression, and said with a look of reminiscence: "That was when I was a child, about five or six years old. One winter it was very cold, and I went to the temple with my family to pray for blessings. On the way back, I was greedy for a while. Wan got separated from them. I lost my way while walking, and suddenly the wind was so strong that I got cold and quickly hid in a corner of an alley."

"At that corner, I saw a beggar huddled, and the beggar was motionless. I was a little scared and thought the beggar was dead, so I pushed the beggar. I didn't expect that the beggar was not dead, and said that I disturbed his sleep, bad For ruining his dream, let me compensate him."

"I was scared, so I quickly gave him the money in my purse. The beggar took my money, muttered a few words about someone who is destined, and took out an old book from his arms to me. He didn't owe me anything. .I took the old book and walked out of the alley, and the servants who came looking for me found me and brought me back to my house."

"There were some strange things written in that book, which I couldn't understand at first. Later, I became more literate and thought it had some meaning, so I just memorized it. I just never had a chance to try it. This time I saw rock salt and just remembered it. There are instructions on how to refine salt in the book."

Xiao Jingyu's face remained unchanged, "I see. I don't know if that strange book is still there, can I take a look at it?"

Tao Anran was full of apology: "My lord, I'm really sorry. That book accidentally fell into the charcoal basin and burned it when I was warming up in the winter."

Xiao Jingyu raised his eyebrows, "Oh! It turned out to be a pity that it was burned. I wonder if there are other things written in that strange book?"

Tao Anran frowned and seemed to be thinking seriously, "I won't remember this for a while. Unless I come across something I just remember. By the way, the book also said that we live on a sphere, that is to say, we live on a sphere." The place is round."

Xiao Jingyu frowned: "It's absurd, the sky and the earth have been round since ancient times. How could we live on a sphere, wouldn't we just fall down?"

Tao Anran wanted to say, you see apples falling from the tree, why don't they fly into the sky.

Forget it, don't embarrass an ancient man.

Seeing that Xiao Jingyu was still staring at him, Tao Anran turned his eyes and said, "Have you ever seen a sailing ship? When a ship travels far, the first thing to disappear is the hull, and the last is the mast on the ship. When the ship returns, it is exactly On the contrary. My lord, have you thought about why this is?"
