Fall in love with the technology tree [Three Kingdoms]

It was summer and June, and the sun was in the sky.The sky has almost faded blue under the sunlight, but under the scorching sun that cannot be seen directly, there are golden fields.

"How's the harvest this year?" Ah Sheng stood on a hill in Weihai Port, Qingzhou, relying on the shade of a tree to avoid the heat.

The person who came to report was Tai Shilang, the county magistrate of Changyang, who had a smile on his face before he could speak. "This year, the weather is good. As long as the summer grain is harvested before it rains, Weihai can also have three years of grain storage."

Asheng put a straw hat on his head to shade the sun, and while walking, he listened to Tai Shilang's report on various data in Weihai, and at the same time compared the values ​​in his mind with those from the Ministry of Graphics and the Ministry of Spy.She will only accept the statements of the three places if they match.

"Although there are few fields in Weihai, the water conservancy is perfect, the farm tools are sharp, coupled with intensive cultivation, the harvest is [-]% higher than that of other places; this year, a few acres of fields are trial-sowed with southern rice seeds and corn, and the growth is gratifying. The old minister thought that he might have corn. It’s just that the specific harvest will not be calculated until the end of the harvest.”

Tai Shilang called himself an "veteran"?

Ah Sheng glanced at him subconsciously, seeing his natural expression, he couldn't help chuckling: "When you sent the grain seeds to the plains, did you meet brother?"

Tai Shilang broke out in a cold sweat when he heard the words, and hurriedly stepped back half a step to show respect: "...Meng Degong is a hero, but he is not as compassionate to the common people as the lord."

A Sheng was silent for a moment, then patted the county magistrate Taishi on the shoulder: "It is inappropriate for me to ask, you continue to speak. I see that the population of mountain people has increased by [-]. What's going on?"

"Ah," Tai Shilang wiped the sweat off his forehead, "last year, the remnants of the Yellow Turbans fled into the mountains and killed many people. The savages in the deep mountains were helpless, so they went down to join them."

Ah Sheng's footsteps stopped: "How come I haven't heard of the Yellow Turban that escaped from Mount Lai?"

"Master, if our casualties are less than [-], it's for the local people to decide on their own. There is no need to report it." Qin Liu who followed behind reminded.

"Oh, yes. And those yellow scarves?"

"Driven out!" Tai Shilang proudly puffed out his chest, "No outsiders were allowed to enter the fruit forest belt. The three mountain villages of Orange Water, Pingfen, and Xiangye have made great contributions, and the pensions and rewards have also been implemented. It's just that they want to be here I can't decide to pave concrete roads in the village..."

Ah Sheng nodded: "You write an application, and I will approve it for you."

Tai Shilang was overjoyed and bowed to salute: "I thank the lord for your kindness on behalf of the mountain people."

"Paving roads and building bridges, canals and dams is what the ruler should do, and it is not a grace."

Tai Shilang was even happier.When Ah Sheng went to inspect and visit the harvested fields, he ran back and forth serving tea and water without stopping for a moment.

Although Weihai is small, there are many small things like the mountain people wanting to pave the road, or the management is greedy for eggs.A Sheng has been busy until the end of the summer seeding, and then he has finished the work of checking for omissions and filling in vacancies.

She lives in Fort Weihaiwu. The mountains are shaded by green trees, and there are ice blocks from the springs, which are far cooler than the mountains below.As soon as Tai Shilang got the news, he ran up the mountain just to enjoy the coolness of the day.

"My lord... my lord, it's not good, Luoyang has another solar eclipse."

"My lord, my son has just been promoted to Xiaolian, how can he be the important task of the prefect. Think twice, my lord."

"My lord, Duke Meng De led his army to attack Dong and borrowed food from us. Should we borrow it or not?"

"My lord...the turmoil broke out in Beihai, what should we do?"

Ah Sheng, who had been as immobile as a mountain, only reacted when he heard the last sentence: "Beihai Kingdom? I remember that the Prime Minister of Beihai Kingdom is..."

"Gongsun Du." It was Qin Liu who was also working at her place.

Ah Sheng became interested, so he got up and stretched his muscles. "Tell me." It was too hot, she only wore a single shirt, the sleeves were rolled up to her shoulders, and the cotton socks thumped on the mat.

"Gongsun Du wanted to send troops to challenge Dong, but the big clan in Beihai insisted on refusing to send them neither men nor food," Qin Liu said.

"These people only care about self-protection, and if they want them to send troops, unless they are given benefits, but Gongsun Du is not a person who is willing to compromise, otherwise he would not have lost his official position as governor of Jizhou. Then?"

Qin Liu curled up his lips: "The Marquis of Beihai secretly welcomed Kong Rong, and wanted to make Kong Rong the Prime Minister of Beihai. We know who Gongsun Du is. He directly surrounded the wedding banquet of the Liu family. There were more than 280 scholars present, all He was killed. Afterwards, each family took revenge and fought Gongsun Du in the city, and the fire lasted for three days."

Human tragedy.

A Sheng raised his eyebrows: "Since it was a secret meeting, how could Gongsundu know about Kong Rong? And who disclosed the news of the Liu family banquet to Gongsundu?"

Qin Liuyi spread his hands: "Gongsun Du and Da Lang are good family friends. Since I have received the news, I will naturally help him."

"You are really rascal." Ah Sheng sighed, and buried himself in the spy department's report, "I'm busy these days, and you didn't remind me. It's such a big thing."

"Since we have taken root in Xuantu County, Gongsundu will definitely not let him go back to Liaodong. If he knows that his hometown has become our Fushun City, then we still have to kill him. Sooner or later he will die, it is better to die Some value."

Ah Sheng found the report on the Beihai Incident, which was more detailed. Gongsun Du died in the war, and the Beihai clan also suffered heavy losses, especially the Liu family, which was almost wiped out.But Kong Rong was clever and ran away in time, saving his life.

"What value are you talking about?"

"In the past, the Toshi people in Beihai were like thorns everywhere; now they are like thorn bushes that have just been caught in a fire, and they can be moved in after simple cleaning."

"Beihai..." Ah Sheng pondered.

"Beihai is the hometown of the great Confucian Zheng Xuan. He has studied for the master in Jiaozhou for many years. Doesn't he miss home at all?"

Ah Sheng took a sip of tea, tapped on the table with his fingers. "Beihai, don't go for now." She finally said.

Now it was Qin Liu's turn to be surprised: "Why?"

"We have expanded our land tenfold in Jiaozhou. Youzhou, Goguryeo, Xuantu, and Liaodong all need to strengthen the city defense. It is too greedy to reach out to Qingzhou now. And my brother is also in Qingzhou. Beihai is better for him than for me. efficiency."

Qin Liu narrowed his eyes, and he didn't know what was calculating in his dark pupils.

"You do the math, the spy department has enough manpower to guard against Xianbei and Wuhuan in the north, and to supply the whole Jiaozhou in the south. Is it enough?"

"My lord thinks about things farther than I do." Qin Liu was convinced.

Ah Sheng closed his eyes: "I have always been long-term."

Thinking about the long-term issue, Ah Sheng did not go to the front line to discuss Dong immediately. She was waiting for a batch of special goods from the south.

In July, the weather is still hot.In such a hot weather, a cold ox cart looked particularly abnormal.And the person pulling the bullock cart wore a black hat and a black veil on his head, which was even more abnormal.Fortunately, he played the banner of the Cao family and came from the port, otherwise he would have been arrested by the villagers before he had walked half a mile.

One person and one car went straight up the dwarf hill where Caojiawu Fort is located, but they didn't go to the mansion, but turned on the main road and went up an unpaved mountain road.The mountain road twists and turns until it reaches the back mountain that is inaccessible.

At the end of the road, there is a narrow stone wall, behind which is a stone house.

The man in black showed the seal, and the guard at the gate raised his hand to salute: "Master Gong, the master has been waiting for you for a long time."

The three layers of white cloth on the bullock cart were untied, and the bottom turned out to be ice cubes, piled up like a hill. Under the scorching sun, the iceberg melted, and water dripped from the cracks in the cart.

The man in black known as Master Gong climbed onto the iceberg, and Bala took a long time to find a sealed iron box from inside.He carefully held the iron box in his hands and entered the room.

Ah Sheng was alone in the room, sitting on a black-painted seat.

"Master." The man in black knelt down and kowtowed deeply, "I'm guilty. Of the 25 students in the Sanya Gewu Institute... Eleven died and eight were injured." He took off his black hat, revealing a severely burned face. The nose and nose were all gone, just scabbed wounds and new growth, twisted together ugly.Tears flowed from the slit of the left eye, which could not be opened, because the path on the face was too tortuous to fall.

Ah Sheng's eyes were red, but her face was hidden in the shadows so that people couldn't see clearly: "You are guilty. I said that soaking cotton in mixed acid is one of the absolutely prohibited items."

The man in black fell on the ground: "The master has the talent and learning from heaven, and knows what is forbidden by heaven and earth. It is me and other mortals who have no fear."

Ah Sheng got down from his seat, bent over to pick up the iron box, and after a few fiddles with it, he unlocked the Luban lock.Iron box with iron box, copper box, kraft paper, sealed layer by layer, and dried with activated carbon.

In the innermost part is a large ball of compacted cotton soaked in alcohol. The snow-white color is just like ordinary cotton.

"It's really well done." Ah Sheng sighed, "If I hadn't seen it with my own eyes, I would have never imagined that such pure nitrocellulose could be made in this era. It has been floating in the sea for a month and there is still no sign of decomposition."

She started to seal the nitrocellulose again layer by layer, and finally restored it into an iron box.

"How many are left?"

"According to the master's book, all dangerous goods totaling more than 150 catties have been destroyed, and the remaining three catties of gun cotton are stable top-grade. I really can't bear it..."

With more than 150 catties of nitrocellulose, the explosive power is equivalent to [-] catties of gunpowder.Ah Sheng rubbed his forehead. "You can't bear it, so what?"

"They will help the master!" The man in black called Master Gong suddenly became excited, "Master, you know the gun cotton, and you know that they are very useful on the battlefield!"

"I know, but—" Ah Sheng snapped, "Once this kind of thing is used to kill people, the casualties will be uncountable."

"Master, master. Sin slave..." He lay on the ground with tears streaming down his face.

"How old are you this year?" Asheng asked suddenly.

"Sin slaves are..."

"You are a second-phase student, from Qingzhou Pingyuan County, 30 years old this year."

The man in black froze. "Master..." His hair was thinning from the burn, but the only bits that were left were all white. 30 years old, looks older than 50 years old.

"Only this time. Take your scary children and let's go to Luoyang."

The author has something to say: nitrocellulose, the product of the reaction between absorbent cotton and nitric acid (sulfuric acid as a dehydrating agent), is flammable and explosive.
