The gunpowder was made by Kaichi while he was helping out in the pharmacy.

He found nitrate and sulfur in the drugstore, and the charcoal was simpler, and the materials were complete, and of course he had to make gunpowder.

In his previous life, he had made gunpowder, and when he was in middle school, it should be a history textbook or a chemistry textbook, and there was an introduction to gunpowder and a recipe. Then one time when he was doing a chemical experiment, he found potassium nitrate, and then he found sulfur, so he took the time to prepare some gunpowder.

At that time, their chemistry laboratory was not strictly controlled, especially when he had good grades, participated in chemistry competitions, and had a key to enter the chemistry laboratory, mainly to facilitate them to conduct chemical experiments. Unexpectedly, he had a big brain, and he prepared gunpowder by himself.

It's just that I don't know if his own ratio is not accurate, or the black powder is not very powerful, the black powder he prepared not only burns relatively slowly, leaving a lot of black solid residue, but also the smoke is very large, but the taste is similar to that of firecrackers.

How can his classmates not show off, after he made the gunpowder himself, everyone else gradually knew. In the end, something happened, and the first time was when someone was pestle gunpowder in a beaker in the laboratory, the gunpowder burned, and the whole laboratory was covered with thick smoke, and the person who made the gunpowder seemed to have added white phosphorus to it. The people at that time were frightened and hurriedly opened the windows and doors to disperse the smoke.

Kaichi was also frightened because he was the initiator, although he never made gunpowder again after the first time.

It's just that people at that time did not learn their lesson, and there were people who made gunpowder. In the end, something big happened.

A man brought gunpowder to the dormitory, fearing that he would be seen, covered it with his hands and placed it between his legs, and the gunpowder spontaneously ignited again. This time I wasn't as lucky as last time, the last time it was just a big smoke, this time, the classmate's face was burned, his hands were also burned, and he was almost disfigured, but fortunately, he came back.

Since then, no one has made gunpowder.

Fortunately, the school didn't pursue it, otherwise, Jia Yi couldn't say what he was doing, he might not be admitted to college, he couldn't be a programmer, he wouldn't die suddenly, and he wouldn't be able to cross over.

The power of the gunpowder he made now is also average, although he memorized the chemical expression of gunpowder, one nitrate, two sulfur and three charcoal (this is not the proportion of ingredients, it is a chemical expression), but because of purity and other reasons, it did not achieve the most ideal effect.

The sound and smoke effect is okay, if you want to really kill, you can probably only rely on scaring to death.

Jiayi said to Yimu that it was his original teacher Yao Lao who taught him how to make gunpowder, and yes, Yao Lao again.

While a few people were talking, the guards of the Lord's Mansion arrived, attracted by the loud sound of Kaichi's "Vine Ball Player Grenade".

Flower sent them away, saying that it was his teacher's sound of experimenting with magic, and threw the pot to his teacher.

"Teacher Imu, I didn't expect you to be a mage. Is there a difference between a mage and a wizard?" asked Kaichi.

"Actually, for you, there is not much difference, you both use spells. Imu replied, "But we generally call those who release spells through study, understanding the rules of the world, and understanding the principles of spells as mages."

"And those who generally obtain spells by offering to other powerful sources of magic are generally called witchcraft. For example, the totems of the northern barbarians and the offerings of the ancient souls, as well as some offerings to the devil. There are even offerings that give back magical feedback.

"Of course, the worship of the gods does not count, we generally call this a priest.

"There is also a kind of blood that flows through the body of powerful magical creatures, and after awakening, it can automatically cast spells, which we generally call warlocks. It's good that you know this, but it doesn't really mean much. ”

Master Imu explained to Kaichi that the three types of spellcasters have different sources of magic, but ordinary people don't know about them, and most of them use wizards to refer to spellcasters.

Kaichi wasn't actually interested in classifying, just looking for an excuse to speak, and he continued, "Teacher Imu, I, can I learn magic from you?"

He looked at Im nervously, his eyes full of longing. This is an opportunity, Master Im seems to be quite talkative, and it is up to him to realize his long-standing extraordinary dream.

"You want to learn magic?

"Because magic is magical, it can do things that many people can't, and she allows me to control my own destiny. Jia Yi said, in fact, the last sentence is the point.

"Who can truly control their own destiny? You are truly fearless and ignorant. ”

When Jia Yi heard this, he asked, "Then, teacher, will you accept me?"

Imu pondered for a moment and said, "No, I don't want to teach one more student, two is enough trouble. ”

When Jia Yi heard this, he was a little panicked: "Teacher, I'm very smart, I've already learned a lot of words, so it won't take too much of your energy." And I will cook a lot of delicious food, much better than the cook in the lord's mansion, and I will bring you food every day. ”

Dai'er also persuaded and said, "Yes, teacher, Jiayi is very smart, and he can learn many things as soon as he learns." And the kitchen is really not as good as his craftsmanship. ”

Flower also said: "Teacher, teach one and three. And we can also learn from each other. ”

But Master Imu just shook his head and didn't agree.

The next time, Imu began to start the official class, but he didn't rush Jia away.

Realizing that this was an opportunity, Kaichi quickly found a stool to sit next to him and began to listen.

In the following days, Jia Yi brought breakfast to the lord's mansion every morning, and when the class began after eating, Jia Yi took out a small notebook and began to audit, and also took notes. Mage Im didn't shy away from him, but he didn't talk about magic directly at the beginning, but talked about some basic knowledge and mathematics.

In fact, Jia Yidu, especially mathematics, he has now completed the knowledge of junior high school, and he is no longer comparable to ordinary people in mathematics.

Kaichi got up early every day and made breakfast and took it to the lord's mansion, and his mother was very strange and asked why. He told her that he was going to learn from Dale's teacher. Then Erica didn't care, in her mind, the tutor of the lord's mansion was better than the "training class" outside, and she wouldn't suffer any loss.

In this way, 8 or 9 days passed in a flash.

After class that day, Imu left Kaichi behind and asked, "Do you really want to learn magic?"

"Yes, teacher. I've been interested in magic since I was a kid and I really wanted to learn it. Kaichi replied.

After listening to Jiayi's words, Master Yimu began to take the test against Jiayi, and almost all of the questions he asked were taught these days. Jia Yi's answer made him very satisfied, Jia Yi did not memorize this knowledge by rote, and understood it very well, and he could also answer some of the knowledge he had not taught well.

"Jiayi, you are indeed very talented. Even if you don't have enough magical talent, your talent for learning can make you successful. But you know, I taught Dale and Flower that the lord had to pay an additional 100 gold coins a year, 100 each. If you can afford to pay the tuition, I'll take you. ”

"You go back and think about it, if you can't, don't come in the future. ”

100 gold coins is not a small amount, and the economic level of the Ejia family can't come up with it, and I don't know if it's okay to pay for meat.
