In January of the third year of Zhenguan,

A school house in Chang'an City, Li Zheng is facing the number of masters, this is a school run by the eldest grandson's family in Chang'an, the children who go in and out here are not rich but also have a solid family, but Li Zheng is a poor peasant child.

If it weren't for the fact that the master was a distant relative of his family, he wouldn't have been able to enter this study house at all.

Li Zheng is out of step with many people here, and students of the same age here don't talk to Li Zheng.

For them, Li Zheng is an outlier.

And Li Zheng often says things that others don't understand and does some inexplicable things.

Who will be idle and have nothing to burn stones? This kind of thing can only be done by Li Zheng, but the stone can not be eaten when cooked.

Even drinking water, Li Zheng never drank it directly, but was willing to drink it after boiling it.

Many children were reluctant to talk to Mr. Lee.

"I've taught you for so long that you can't even write a word, don't come here in the future." The master said to Li Zheng.

A group of students in the study room were talking and saw Li Zheng leaving with his book bag.

I walked out of the study room to breathe in the fresh air, and my mood improved a lot.

It is said that as a time-traveler, I can't even write an ancient word in this era, and I may be the saddest time-traveler in history.

Leaving the study house and kicking off the stones at your feetSince you can't read the book, today is also the last day for me to go to work at the Hongwen Museum.

Reading is something that ordinary people can't even think of.

Li Zheng is the most inconspicuous scholar here.

As always, Li is sorting through the books.

Although the Tang Dynasty already had paper, most of them still used bamboo slips.

Picking up a roll of bamboo slips, Li Zheng saw a question: "Today, someone buys things together, each person pays eight yuan, and the surplus is three yuan; Each person paid seven dollars, less than four dollars, and asked the number of people and prices.

The Tang Dynasty already had this kind of math problem? The solution to this problem requires assumptions about units, which you can calculate as long as you know how to set unknowns.

If you don't know how to set the unknowns, it will be very complicated to calculate, as long as you set the unknowns, it will be much easier to calculate.

In any case, on the last day of work here, Li Zheng didn't have to worry so much.

After typing out a draft with a brush, write the answer on a bamboo slip, seven people, fifty-three dollars.

Pick up another copy that says about the war.

Jieli Khan led a 100,000-strong army to garrison north of Yinshan, and General Li Jing's 100,000-strong army garrisoned south of Yinshan.

It's so difficult to attack head-on, why don't you change your thinking, Li Zheng wrote a more famous plan similar to Tui'en Ling, but fortunately, he often looked at the hundred pulpits before he crossed.

Seeing that someone was coming back, Li Zheng hurriedly sorted out the books here.

The director of Hongwen Pavilion saw that Li Zheng had sorted out the books here, took out a few pennies and said: "You were driven out by the master of the eldest grandson's family, and you don't have to come here today to sort out the books. ”

"Thank you, Principal." Li Zheng took the money and turned around and left, without looking at it too much.

Walking on the huge Chang'an City, Li Zheng is breathing fresh air and is finally free.

I bought a few naan cakes in Chang'an City to satisfy my hunger, and there was a small village by the Jingyang River outside Chang'an City.

This is his home in this era, when his father followed Li Yuan to fight, he made a meritorious contribution after helping Li Yuan block an arrow, although he was not knighted afterwards, but he was given a few acres of land for military merit.

He is a small landlord in the village, and although he is living in poverty, he can't go hungry.

"I'm back." Li Zheng arrived home and threw his baggage aside.

"Why are you back? You don't read anymore?! Li Zheng's father Li Daxiong said in surprise.

Li Zheng took off his bound cloth shoes, put on loose and comfortable straw sandals, and said, "I'm too stupid to learn to be kicked out by my master." ”

Hearing this, Li Daxiong, who was full of scum, slapped the case, "Is there someone in the study house who bullied you?" ”

"Nope." Li Zheng took out a persimmon from the bamboo basket and ate it.

"Is that the money we give is less?"

"Not either."

"Then why are you back?"

"I said that I was too stupid, and I wouldn't starve to death if I farmed with my father in the future, right?"

Li Daxiong was silent for a while and said: "Today, my father is going to follow the village to the mountains to hunt, and we will eat meat at night. ”

As he said this, Li Zheng could still see the loss in his eyes.

After saying that, Li Daxiong lifted a stick and went out, he didn't say anything, nor did he blame himself, saying that father and son depend on each other, and now looking at the back of him leaving, it seems that there is still a little tragic.

Li Zheng sank down again and thought that he had failed to burn glass several times, and when he took out the experimental records he had done in his baggage, the first thing to solve was the problem of life.

Before the crossing, it was three meals a day, and it was really unbearable to suddenly become two meals a day, and it was still in the stage of growing the body.

The villagers shook their heads and sighed when they saw Li Zheng burning stones in his yard.

"Is this Li Daxiong's baby stupid, what are you doing burning stones?"

"It's not a problem, I heard that this kid was kicked out by the scholar because he was too stupid."

"A clean child, how can he be stupid."

"Do you think that our village can produce a scholar to be an official?"

"It's pitiful."

The village was shouting and shouting, and the men of the village gathered at the head of the village to go into the mountains to hunt.

Li Zheng pulled out a few crystal glass balls from the fire.

{The firing of the glass is complete, and the pharmacy is opened for a stage.} ｝

After receiving the system prompt, Li Zheng looked at the whole system as a system similar to the construction of a city-state, and looked at the current information: the territory is 300 acres, the cultivated area is 60 acres, and the population is 120.

Looking at the new task, reclaim 100 acres of wasteland and start the first stage of crops.

I sold the glass first, and the three glass beads were only the size of mung beans, even if they were only so big, they could be sold at a very high price in Chang'an.

Early the next morning, Li Zheng found a relatively reliable place in the local area, taught the rules for others, and asked him to sell the three glass beads for two silver cakes.
