The teenager's name is Zhang Shouliang.

Although his father was just an ordinary jinshi, his mother was the younger sister of Li Jingzhong, the king of Zhaojun in Chizhou. He grew up in the palace since he was a child, lived a life of fine clothes and food, plus he was smart and studious, and he was very loved by Li Jingzhong.

Originally, the trajectory of his life was to be admitted to the Jinshi and become an official of the Tang court, but unfortunately in this troubled era, his fate was the easiest to change.

Because Chizhou was defeated by Ning Guojun, Li Jingzhong only sent his son away, and he defended the city to the death, he committed suicide when the city was broken, and Zhang Shouliang's family was imprisoned by Ning Guojun, and his mother and father died of illness one after another.

He thought that he would also die in prison, but later Ning Guojun fought with the Tang army and suffered heavy losses, so Lu Weiyi asked his subordinates to pull the strong prisoners in the prison into strong men, and the thin ones were thrown directly on the street and left to fend for themselves. Because there is no surplus food left in the prison to feed these prisoners.

Zhang Shouliang, who had just been released from prison, was extremely weak, but fortunately he was rescued by a woman surnamed Xue who sold breakfast, and since then he has been doing chores for Aunt Xue every day and helping to take care of her daughter Xiaoyue, and his life can go on.

However, the good times did not last long, the husband of the woman surnamed Xue was a soldier of the Ning Guojun, and one day, the news of her husband's death suddenly came out of the army, and without her husband's support, the bully began to bully her.

Zhang Shouliang resisted a few times, but his weak body was no enemy of bullies, and he was beaten very badly every time, and the small early shop finally couldn't hold on.

Aunt Xue couldn't pay the rent, so she finally went to the streets with her daughter and Zhang Shouliang. Since then, the three of them have lived by begging and living in a ruined temple far from the city.

Not long after, Aunt Xue became ill and fell ill, and the daily food source for the three of them fell on Zhang Shouliang alone.

Although he grew up in the palace, he is an extremely strong person in his bones, and he knows how to repay his kindness, thinking that even if he wants to die, he must repay Aunt Xue for saving his life before he dies.

So in addition to begging for food every day, he would also go to Langzhong in the city, hoping that they could save Aunt Xue's life.

But how can Lang Zhongke run so far for free to treat people, he is blasted out every time, but he never gives up, the emperor lives up to the painstaking people, finally there is a kind Lang Zhong asked about Aunt Xue's illness, and prescribed a prescription for him, Zhang Shouliang went to the pharmacy to catch the medicine according to the prescription, and turned around and ran after getting the medicine.

Where would the pharmacy Xiaoer let him go, chased a few streets, and finally caught up with him, but found that the medicine on his body was gone.

After beating Zhang Shouliang hard, the second child of the pharmacy left. When Jin Yuanwu met Zhang Shouliang, he saw him who was beaten to the ground.

In the ruined temple.

Zhang Shouliang gave Xue Xiaoyue the remaining half of the steamed bun he had just eaten, and then went to the small river near the broken temple to fetch water, light a fire and decoct the medicine, and was busy until midnight before feeding Aunt Xue to drink the medicine.

After that, he tore up a steamed bun, soaked it in water, fed it to Aunt Xue, and then fell asleep.

Early the next morning, seeing that Aunt Xue's face was much better, he finally relieved himself, took another steamed bun and tossed it, boiled it in water, and the three of them shared it.

Then, he went to the city to inquire about the situation of the army yesterday, and he received the great favor of Jin Yuanwu, so he naturally wanted to inquire clearly, so that he could repay in the future.

When he learned that they were troops from Hui'an Mansion, Zhang Shou made a decision to take Aunt Xue and Xiaoyue to Hui'an Mansion!

He had planned to leave Chizhou for a long time, but because of Aunt Xue's illness, it had been delayed so far, and the officer's friendly behavior gave him a glimmer of hope, and he decided to go to Hui'an Mansion to gamble on his luck.

It's all about survival.

The next day, when Aunt Xue was finally able to stand up, Zhang Shouliang spoke: "Aunt Xue, let's go to Hui'an Mansion!" ”

"Huh? What the? Aunt Xue still looked a little confused and reacted very slowly.

"I said let's go to Hui'an Mansion." Zhang Shouliang said patiently.

"You just decide." Aunt Xue said in a low voice.

"Xiaoyue, would you like to go?" Zhang Shouliang asked again.

"Is there anything to eat in Hui'an Mansion?"

"Yes, you can let Satsuki eat with her belly open."

"Then I'm going, brother, take Xiaoyue quickly!" Xue Xiaoyue had a smile on her face.

"Don't worry, I'll take you there." Zhang Shouliang said firmly. After that, the three of them simply packed up their salutes and began to set off to the east!

Along the way, the trio ran out of food quickly, and several times they were driven out of the village while begging, and they had to find some edible plants and fruits on the way to satisfy their hunger.

After walking for a while, Xue Xiaoyue fell ill, and Zhang Shouliang had to carry her forward, and when the three of them finally entered the territory of Hui'an Mansion, the worst thing happened, and Zhang Shouliang finally fell ill.

……

When Zhang Shouliang opened his eyes again, he found that he was lying on a bed, and there was a bowl of porridge on the table next to the bed. Zhang Shouliang held back his appetite and shouted loudly: "Aunt Xue? Moon? Where are you? ”

Soon, there was a sound of footsteps outside the house, Xue Xiaoyue ran into the room quickly, and smiled at him: "Brother, you finally woke up!" ”

Aunt Xue also walked in slowly, her expression was surprisingly good, with a smile on her face, and there was a generous man next to him.

"Aunt Xue, where are we?" Zhang Shouliang asked eagerly.

"This is Xiaohe Village, it was Brother Wang who saved us, and he also asked Langzhong in the city to treat you." Aunt Xue looked at the kind man with indescribable gratitude.

Zhang Shouliang was stunned for a moment, then lowered his head, his nose was sour, and there were faint tears flowing out of his eyes, and the negative emotions accumulated during this period of time were instantly washed away by this kindness.

He blinked vigorously, squeezed away the tears, and asked, "How long have I been unconscious?" ”

"My brother has been lying here for five days." Xue Xiaoyue clapped her hands and said.

"Really?" Zhang Shouliang struggled to get up and bowed his hand to the honest man: "Thank you, Uncle Wang, your kindness will never be forgotten in the future." ”

The thick man hurriedly helped him up and said, "Don't be like this, I didn't actually do anything, your body is not well, take a good rest." ”

Zhang Shouliang saw that Brother Wang was a little at a loss, so he put away his etiquette, lay down on the bed, and said with a smile: "Uncle Wang, I listen to you." ”

"Okay, okay." Brother Wang looked very happy and said with a smile: "I'll kill a chicken to make up for you." ”

Zhang Shouliang was taken aback and hurriedly said, "No, no, I'm almost fine." ”

Brother Wang was willing to listen, and hurriedly left the room.

Zhang Shouliang looked at Brother Wang's back, his face became softer and softer, and he said softly: "Aunt Xue, we are here, will we cause trouble to Uncle Wang." ”

They have three mouths, and he is afraid that the three of them will affect the livelihood of Brother Wang's family.

Aunt Xue smiled and said, "Don't worry, your decision to bring us to Hui'an Mansion was right, the villagers of Xiaohe Village are living a good life." But then again, we must not forget Brother Wang's kindness, and we must repay it in the future. ”

Zhang Shouliang nodded vigorously and said, "I will." ”

Aunt Xue was silent for a moment, and then said: "Shouliang, I want to live here, Brother Wang said that as long as we go to the city to register the identity of the homeless people, and then let the village chief help intercede, we can settle in Xiaohe Village, do you say?" ”

Seeing the expectant look in Aunt Xue's eyes, Zhang Shouliang knew that she didn't want to run around anymore, so why shouldn't he himself?

"Okay, I'll listen to Auntie!"

Xue Xiaoyue on the side cheered: "It's great, you can live in Xiaohe Village!" You can eat with your belly open! ”

Seeing Xue Xiaoyue's smile, Zhang Shouliang also showed a smile on his face, and a few days later, with the help of Brother Wang and the village chief, Zhang Shouliang and the three of them became villagers of Xiaohe Village.

Hui'an City, Engineer Academy.

On an open field, Lu Yuan was watching the invention of the first firearm of the Engineer Academy, the Fire Cloud Pigeon.

After more than a year of improvement, Lu Yun'er finally designed this firearm, the pigeon is equipped with explosives, and a rocket is tied under the stomach to be used as a booster, in Lu Yuan's opinion, this is simply an ultra-small missile.

However, the accuracy and power are much worse, and the flight distance is also pitiful, and it only flew about a hundred meters before it fell, and it is basically useless at present.

"Lord Lu, I'm sorry, I've been researching for so long, spending so much money, but the power is so small." Lu Yun'er was a little ashamed.

"It's okay, make progress slowly, after all, you used to study the mechanism repeater, so it's naturally slower to get started." Lu Yuan patted her on the shoulder and encouraged.

In his memory, the Divine Fire Crow similar to the Huoyun Pigeon in history was invented during the Ming Dynasty, although the size of the Shenhuo Flying Crow is much larger than the Huoyun Pigeon, and the flight distance is more than 300 meters, but Lu Yun'er only spent more than a year to study something similar, and it can be seen that she has great potential.

Coupled with the fact that she is very young, Lu Yuan has great expectations for her.

Moreover, Lu Yuan knew that the real reason why the fire cloud pigeon was not powerful was in the gunpowder.

Historically, the earliest gunpowder was refined by alchemists, but the real mature method of refining gunpowder was the sulfur fire method invented by Sun Simiao in the early Tang Dynasty.

Therefore, in order to develop firearms, it is necessary to first improve gunpowder.

He decided to recruit a group of craftsmen in the future to specialize in the method of improving gunpowder, and as far as he knew, the proportion of nitrate in modern gunpowder in later generations was three-quarters, so let them study it in this direction!

However, gunpowder alone is not enough, and guns that can really play a decisive role require extremely high iron-making technology. In ancient times, there were two methods of forging and casting, but no matter which method is used, it is not possible to make a barrel and a barrel at present.

This requires recruiting some very good blacksmiths and investing money to let them experiment and improve slowly. All in all, if you want to climb the tech tree, you need to burn money.
