"Sir!" The student who bumped into Ye Hui was scared, for fear that his study career would be over, so he quickly knelt down and helped Ye Hui up.

"Sir, I didn't mean to!" The students who passed the ball were also afraid, for fear that Mr. would blame.

"You didn't mean it, you did it on purpose!" Ye Hui shouted.

All the students knelt down, not daring to make any more noises.

Seeing that the joke was getting bigger, Ye Hui patted the dust on his body, shook his head, and said, "Mr. won't eat you again, really." ”

The crowd still did not dare to speak, and they were afraid to die.

"That's it, it was the gentleman himself who asked to join you, I didn't notice it, there were occasional bumps and bumps in the play, isn't it normal?" Ye Hui showed a motherly appearance.

The students finally relaxed a little.

Ye Hui was actually quite depressed, and felt that his usual attitude was not strict, how could these students be afraid that they would die of fear. Sure enough, is the status of the ruler too high, even in this square inch school, his status as the "principal" is supreme, this concept is deeply ingrained in the hearts of people in this era.

Thinking of this, Ye Hui felt that he was continuing to play with them, and they would not let go, so he thought about it or gave up, and stopped disturbing everyone's Yaxing.

"Go on, remember to prevent colds after exercising, and don't forget to read Wen Shu when you go back." After Ye Hui finished speaking, he took his robe and left.

Hearing a long sigh behind him, Ye Huixin said that he was really afraid of me.

Depressed and returned to the bedroom, Diao Chan was holding Wen Ji's hand and chatting, and bursts of laughter came from time to time.

Ye Hui, who was a little bored, suddenly became interested again, leaned over with a smile, and said, "What are the two young ladies talking and laughing about?" ”

"It's not a big deal, it's just that I heard Wen Ji say that there are finally some girls in the academy now." Diao Chan said.

"Yes, it is also my original intention to set up the 'examination' system to let women study more, I hope everyone can participate in the study fairly, and it can't be said that 'women are virtuous if they are not talented'." Ye Hui talked eloquently, not missing any opportunity to pretend to be thirteen.

"So, sir, do you know what Chan'er and Wen Ji know?" Diao Chan asked with a smile.

"Got it?" Ye Hui asked suspiciously.

"There are many little women who secretly send Qiu Boli to Wen Ji, but there are also a few who have bad eyes, and secretly discuss that they like Mr." Diao Chan laughed out loud.

Wen Ji on the side gently pulled Diao Chan, a little embarrassed.

"It's understandable that I fell in love with Mr. Wen at first sight, why does Mr. Wen Ji also have female admirers?" Ye Hui's expression was natural, and his face was thick-skinned.

Diao Chan and Wen Ji rolled their eyes at the first half of Ye Hui's sentence together, and Wen Ji was silent about the second half of the sentence.

"Probably because Mr. Wen Ji has a beautiful face and is full of wealth, so those female classmates who led him took Wen Ji as a role model, and over time they fell in love." Diao Chan analyzed with a smile.

"Then it seems that if the gentleman doesn't work hard, he will be surpassed by those girls." Ye Hui joked with a smile.

caused Wen Ji to rush out of the door, unable to withstand Ye Hui's attack.

The next day Ye Hui was free.

There was time to study how to make gunpowder.

Gunpowder was originally discovered and invented by Chinese alchemists around the ninth century, and then guns and other weapons came into being, and warfare gradually entered the age of hot weapons from the age of cold weapons.

Since then, gunpowder, movable type printing, papermaking, and the compass have been called the four great inventions of ancient China.

This Ye Hui is shrewd, there are a total of four great contributions to the invention in ancient times, and he alone accounts for two, so that when he came to the later generations, people's admiration for this son is unmatched.

Although Ye Hui felt that it was a shame to be like this, but he said in his heart that it was not my own choice, I just asked for it, and the person who provided it was obviously Xiaoxiao.

That is, Xiaoxiao is not here now, otherwise he must scold Ye Hui: "Although I am not a human, you are a real dog!" ”

After affirming himself, and waiting for the little guilt that remained to be extinguished like a charcoal fire that was about to burn out, Ye Hui finally planned to start making this gunpowder.

Gunpowder is mainly a black powder mechanically mixed with potassium nitrate, charcoal and sulfur, which can be burned by high heat such as sparks and flames.

The advent of gunpowder has promoted the progress of world civilization, and its influence will even exceed that of the other three inventions, because this thing can really hurt people.

So without much to say, Ye Hui went out early and returned late for a few days.

In ancient times, gunpowder was made from sulfur and realgar to synthesize saltpeter, and then fired with honey. But after the honey is burned, it is carbon, so just go and get some coal.

These three things are not difficult to get by reasonably. In fact, most of the ancient inventions are not difficult to make, because the ancients did not have textbooks, let alone advanced technology, so it is the same as playing a survival game without explanation, which requires many, many generations of continuous trial and effort, so that there are various inventions that we are used to today.

After several baptisms of Ye Hui's invention, this person's popularity in Yuzhou at the moment can be said to be as good as an explosion, and the people just kneel and call him God.

With such popularity, naturally everyone wanted to get acquainted with him, from the squire to the commoners; From 80 to 10 years old, all without exception.

This connection is not coming.

Ye Hui didn't know many people himself, so he asked the shopkeeper of the pottery factory, who had also made a lot of efforts to make wine before, to introduce him. He thought to himself again, and said, "This gunpowder is made of a combination of various ores, and the clay of the king's shopkeeper is also related to the stone, so he must know some people who can open mines." ”

The two haven't seen each other for a while, but they are much closer than before when they get together again, and they directly take the big hand together to the living room of the king's shopkeeper and sit down, and the doorman has a cold but does not dare to squeak.

Ye Hui will be so close to this uncle, naturally because he has a request for the king's shopkeeper; And the shopkeeper Wang is because of the income from the sale of wine-making utensils, good guy, the money earned from selling in such a short time is almost worth the income of half a year, so don't hurry up and hug Ye Hui's thighs.

"What is the reason for this visit, sir?" Shopkeeper Wang motioned for his subordinates to prepare wine and food, and then said to Ye Hui.

"Oh? Shopkeeper Wang, can't I come to see you? Ye Hui said with a smile.

"Then where can I, sir, a busy man who cares about the world, have time to come and see me as a small businessman?" The shopkeeper waved his hand.

"Hahaha, this makes the king's shopkeeper say it well. However, the water mirror did have something important to ask for. Ye Hui began to get down to business.

The shopkeeper Wang's eyes flashed: "Sir, please speak, Wang will do his best." ”
