"Master Hou! Master Hou! It's me! ”

Far away, a man who pulled up his trouser leg began to call.

Needless to say, Wang Laogen.

This guy didn't know where he got the interest today, but he actually volunteered to come and help, and he dug this long simple canal.

"Wang Laogen, if you don't go to the farmland, what are you doing here?"

Qi Ping frowned.

The farmer has the wisdom of the peasant, Wang Laogen's face is not red or panting, patting his chest and saying: "Master Hou, Mr. Qi Ping, I can work, naturally I can rest for a while!" ”

Li Hui smiled, "Wang Laogen, remember to tell other farmers that every household will water at a fixed time and at a fixed time, and they will not wait for the expiration date, and they will come in turns, and they can't fight." ”

"Yes! Master Hou! I promise here that if someone robs and fights, I will get out of Lantian in the future, and I will never have the face to see you again. ”

Qi Ping laughed out loud, "Wang Laogen, you don't have to roll out of the blue field, the distribution of farming and watering is uneven, if the Hou Ye doesn't look for you, I will also look for you, even if I don't look for you, those farmers will definitely make a mess of this canal." ”

For farmers, Qi Ping understands very well that a bowl of water is not good for leveling, so you have to say it in advance, otherwise, if you are not satisfied, no one can use this canal and this waterwheel.

People who have not been to the grassroots may not know the doorway, but as long as someone has worked at the grassroots level, they will understand that even the rain and dew are the best way to distribute benefits.

This benefit doesn't have to be much, but everyone must have it!

Qi Ping thought for a while, "Wang Laogen, you remember, you and Liu Da are now responsible for conveying the news of the farmers, so do what you do, do it well, and you will be rewarded." ”

As soon as he heard that there was such a good thing as a reward, Wang Laogen immediately walked with the wind, "Master Hou, Mr. Qi Ping, I'll go over and talk to them well." ”

Back in Shushan, Li Hui immediately asked Li Tai to start drawing according to the principle of a simple waterwheel, physical things are no longer a problem for Li Tai, Li Hui was not a smart student before he crossed over, but he had seen a non-mathematical theological tyrant, that kind of monster-level person is no longer imaginable by ordinary people.

Sleeping in class, playing basketball after class, people are resting when you are working hard, and people are still resting when you are resting.

As a result, at the end of the period, the scores of these perverts are higher than the other.

There are also a few single perfect score players at every turn.

You can pass the exam because you can only pass.

People's scores can be infinite, without any upper limit, just because there are only 100 or 150 points on the paper, which limits people's performance.

Li Chengqian, Li Tai, Li Ke, obviously such people.

Li Hui looked at Li Tai's homework book dumbfounded, and the dense calculation formulas on it were already comparable to the junior high school students in later generations.

The design of the waterwheel is actually not particularly complicated, and after Li Tai saw it, he quickly began to move.

When Li Hui was just about to leave, Li Ke ran over, "Teacher, I found a good thing." ”

I don't know where I got the paint, but under Li Ke's high temperature heating, a trace of black liquid appeared.

Li Ke slowly took out the small bottle, poured a few drops on the ground, and threw a fire fold over.

In an instant, the oil on the ground began to burn violently, and the flames rose more than thirty centimeters high.

Li Hui's face darkened, this kid won't be studying weapons all day long, right?

"Teacher, this is what I extracted from the leftover paint at home."

Li Hui shook his head, "Li Ke, do you think this thing is fierce?" ”

"Teacher, it's absolutely fierce, you can catch it on water, but the burning time is too short."

Li Hui smiled, "The teacher told you a real artifact today, but you have to promise that you can't leak it before you are twenty years old." ”

Fierce fire oil, the product of a mixture of real alcohol and kerosene, cannot be extinguished by water, nor can it be separated from sand, and the smell is extremely pungent, and once ignited, one can only hope that this thing will burn out early and extinguish itself.

To make matters worse, the smell of the burning was very poisonous......

This thing, Li Hui thought about it, even if he didn't say it, Li Ke would be able to think of it in the future, Li Er's children are not stupid, they have been bold since they were young, now give them a set, let them abide by the rules, and in the future, they have been educated, if Li Ke really uses chemical means to make things happen, he is not responsible as a teacher.

After all, there is nothing wrong with knives, there is nothing wrong with chemistry, and there is nothing wrong with knowledge.

It's only people who are wrong.

Li Hui slowly wrote down some small words on the paper, as well as a few formulas, and the method of refining.

The more Li Ke looked, the brighter his eyes became.

"Teacher, is this thing easy to use?"

"Remove that word, if this thing is used on the battlefield in the future, it is estimated that there will not be many living people in a war."

As soon as Li Hui finished speaking, he regretted it a little.

Especially when he saw Li Ke's fanatical eyes, Li Hui felt that he had taught a little early.

Li Ke said to himself, "No one should dare to bully the imperial brother now, right?" ”

The three brothers were indeed wearing the same pair of pants.

Far away, Yang Er shouted, "Master Hou, there are bugs!" It's locusts! ”

Li Hui jumped up violently, and the whole person became nervous.

So soon, the locusts came?

It's only been a few days since the beginning of spring!

Leaving Xiao Li Ke, Li Hui came directly to the farmland.

Yang was holding a worm in the second hand, the wings were not completely hard, and the color was also green, so there was no doubt that it was a locust.

But at this time, the locusts have not yet been fully formed, they are just larvae, and they can't fly far, they can't fly.

But the ability of this larvae to nibble is extremely amazing.

"Yang Er, you and Tian Er are responsible for cleaning up the locusts these days, releasing all the remaining chickens, ducks and geese in the farmhouse, and letting them eat happily!"

"Yes, Master Hou!"

Li Hui held the locust in his hand, and his mouth was shutting out, this half-green thing was struggling in Li Hui's hand, and the serrated hind legs were not hard enough, just soft barbs.

Where did Li Hui see the locust plague in later generations, under the early warning mechanism of later generations, locusts have not yet entered the field of vision, and may have been eliminated in the bud by various biological methods and chemical methods.

"Looks like the locusts are coming!"

Li Hui walked slowly all the way, with his hands behind his back, and as soon as he arrived at the door of the house, he found that there were three more people at the door.

It should be said that there are four people, three adults and one child.

The child looked sleepy and could fall asleep standing up.

And the three adults, Li Hui is no stranger, Yuan Tiangang, Xuanzang, and the other one looks extremely energetic, with a pair of eyes revealing wisdom.

Today, Li Hui was wearing ordinary clothes when he went out, and he looked no different from the servants at home.

"Old Yuan, what's wrong?"
