Xuanyang City.

A small town that can accommodate more than 20,000 people, and five or six thousand people live.

There are slums, there are courtyard areas where the rich live, and there are small courtyards where the middle class live.

However, it is more likely to be a kind of shop that combines accommodation with a mixture.

Middle-class people who have shops or group stores to do business have their daily lives of opening shops in the morning and closing work in the evening.

The people in the slums go to these shops to work, or set up stalls on the streets, and sell rock sugar gourds or something.

The rich people inspect their business every day, tease the birds in their spare time, go to the teahouse to listen to books, go to the kiln, go to the Goolan to listen to music, and so on.

Of course, there are also some sons and brothers who meet to go hunting on horseback.

In addition to all kinds of gambling stalls, kilns, hook fences, etc., the rest of the gang business is to trade with caravans from other places, or give local information to other countries.

Because Chechi is the key point of the Silk Road in the Central Plains, there are many caravans coming to the surrounding towns of Chechi.

It's not just caravans from the Central Plains.

There are also caravans of the Treasure Elephant Country, the Black Chicken Country, the Daughter Country, and the Chechi Country itself.

It can be said that before Zhao Lei and the other monsters entered here, Xuanyang City would be very prosperous and lively every day.

It's a bit like a small town dedicated to tourists and tourists.

Zhao Lei and other monsters, after entering the mastery here, at the beginning, the entire Xuanyang City became very deserted, and the quality of life of the people also decreased a lot.

Mainly many commodities, seasonings and other daily necessities, Xuanyang City is purchased from other caravans.

After these caravans did not dare to come to Xuanyang City, the daily necessities were used less and less, and the quality of life inevitably began to decline.

After being in charge for a while, Li Jincheng sent caravans to other towns to buy them, so that the quality of life was maintained at the same level as before.

Then when Zhao Lei was out of the customs, Zhao Lei sent the little demon to 'invite' the passing caravan to Xuanyang City.

These caravans saw that the monsters not only did not harm them, but also took the initiative to help load and unload the goods, so they slowly let down their guard.

After that, monsters have become the unique style of Xuanyang City.

There are more and more caravans that dare to come to Xuanyang City, as well as tourists who come to sightsee.

Xuanyang City has only then restored its former prosperity and liveliness.

No, it should be said that it is more prosperous than in the past.

Because monsters have become the signboard of Xuanyang City.

If it weren't for the lack of cameras in this era, maybe everyone would still be rushing to take pictures with these monsters.

Therefore, the lives of the people living in Xuanyang City today are basically not much different from before. The only difference is ......

They are now more like a big family.

Zhao Lei stipulated that the entire Xuanyang City should read and write together, and in modern times, it is to gather the adults of the entire building together and go to the big group building together, which will undoubtedly promote everyone's feelings and interaction.

Even if there are occasional quarrels, due to the existence of Zhao Lei, the tiger king, at most they will make a small fuss, which is harmless.

There is a more important point because of Zhao Lei's casualness.

Zhao Lei pays attention to the application of learning, pragmatism and practicality.

Xuanyang City did not have a large enough place to accommodate students, so Zhao Lei ordered everyone to start classes in Yamen. If the ordinary magistrate did this, he would definitely be sprayed to death by those older generation of readers.

But who is Zhao Lei?

He doesn't keep tradition, who dares to scold him?

So, Zhao Lei liked it, so he took classes in the yamen.

I was happy and happy, so I went to a vacant courtyard house to do extracurricular activities, and this opportunity to provide a place to hold classes was still grabbed by these outsiders.

Because Zhao Lei will help them advertise their business by the way, and when travelers and caravans come to Xuanyang City, he will instruct the little demons to give priority to introducing these rich businesses that have contributed to Xuanyang City.

In general, it is a happy and thriving scene.

This day is another day of extracurricular activities.

However, this time, Zhao Lei did not choose to take everyone to the yamen or the courtyard in the city, but to bring everyone to the vicinity outside the city gate.

Many people will take a few more glances when they pass by.

Of course, Zhao Lei didn't do this to attract attention.

Rather, he commanded some time ago to collect zinc, tin, lead, copper, silver, and gold...... After waiting for these metal materials that can make electricity, there is finally a new progress!

Although the metal material for making electricity has not yet been collected, in the process of collecting, he has made an interesting thing, which is black powder!

In order to develop the spirit of the common people to explore new things, Zhao Lei specially asked everyone to come to the open space outside the city gate today to do an experiment.

Soon, when the personnel were almost there, a rich kid couldn't help but ask: "Hey, hey, Tiger King, what's the interesting stuff to play today?" ”

I have to say that since Zhao Lei started teaching.

These rich children, who have nothing to do on weekdays, are even more enthusiastic.

Because of the interesting knowledge that Zhao Lei taught them, as well as extracurricular activities, it is much more interesting than teasing birds, fighting crickets or something.

Zhao Lei said incomprehensibly: "Don't worry, you'll know later." ”

It didn't take long for someone to move a table next to Zhao Lei.

And they set up brimstone, and charcoal, and saltpeter on the table.

Zhao Lei came to the back of the table and said to everyone: "What I want to teach you today is chemistry!" ”

"Chemistry?"

Everyone is confused, you look at me, I look at Ling, I don't know what their Tiger King is talking about.

Even those caravans passing by who wanted to gossip couldn't help but stop and want to see what chemistry was.

Zhao Lei said with a smile: "Chemistry is that when you fuse different substances and different doses together, they are likely to have different effects. For example, these three items on the table. ”

"Brimstone, you know, right?"

Everyone nodded.

"Charcoal, you know, right?"

Everyone nodded again.

"It's called saltpeter, and maybe not many people know about it, but that's okay. It's not the focus today. Today, I want to show you what changes will occur when these three substances are fused together. ”

Immediately afterwards, Zhao Lei began to make black powder in front of everyone.

Everyone is still confused.

What did the Tiger King do with all this black stuff?

It didn't take long for the black powder to be ready.

And put a certain amount on the ground.

For this novelty, the rich children are extremely studious and active: "Tiger King, what is the use of this thing? ”

At the same time, I thought to myself, could the so-called chemistry be the way to mash and stir several different things together to turn them into something black?

Zhao Lei smiled slightly.

Then he picked up a piece of paper, used the electricity in the Five Thunder Rectification Method, released a little electric current, ignited the paper, and then threw it at the pile of black powder on the ground.

The moment the flame touched the black powder, the black powder suddenly hissed and burst into flames.

Immediately startled everyone present.

The Tiger King will play with fire, they can understand.

But how could such a small flame suddenly erupt so strongly after touching that black thing?

The rich kid was dumbfounded and stammered, "Tiger King, this ...... Is this a spell? ”

While beckoning to the rich kid, Zhao Lei smiled and said, "This is not a spell, you can also come and try it." ”

The rich kid subconsciously walked over.

Then Zhao Lei made a bunch of black powder and put it on the ground.

And after lighting a piece of paper, he handed it to the rich child.

The rich kid took the lit paper.

Step by step, cautiously walk towards the black powder.

The flames were about to burn his hands because he was walking so slowly, he quickly threw the paper away, and the whole person bounced backwards.

Hisss Hiss!!

The same scene happened again.

This shocked everyone present, including the caravan that stopped to eat melons!

This time, they actually saw it!

The flames were thrown down by the rich kid himself!

Could it be that this so-called chemistry is a science that allows mortals to cast spells even if they can?!

Zhao Lei ignored everyone's shock and continued to explain: "Everyone also saw it, right? What I handed him was nothing more than an ordinary flame. In other words, no matter who you are, as long as you master this science, you can achieve such an effect. ”

Uproar——!

In an instant, the audience was in an uproar!

Spells!

Mortals can cast spells, too!

Immediately afterwards, one after another people in the crowd raised their hands and excitedly said, "Tiger King, can I try it too?" ”

"Tiger King, can we try it too?"

Zhao Lei reassured everyone: "Okay, okay, but there are not enough materials prepared today, and everyone can only test in groups." ”

Next, it was a group of middle-aged and elderly people who conducted an experimental conference on black powder together.

There are successes and failures.

Everyone was very excited.

It didn't take long for the rich kid, who finally recovered from his excitement, to suddenly ask: "Tiger King, this thing is very fun to play, but what does it do?" ”

Zhao Lei watched left and right.

At this time, Yang Yang and a few bear children from Lijia Village walked out of the city with rock sugar gourds.

Zhao Lei grinned and beckoned to Yang Yang: "Yang Yang, come here~"

Several bear children jumped in front of Zhao Lei and licked the rock sugar gourd: "King~"

"The king is playing a game with you. Do you see a lump of cow dung over there? ”

The bears nodded.

"You bury this thing in cow dung. Then light it with fire, count it to three times, turn around and run, don't you understand? ”

"Oh!"

Then I saw Yang Yang take the small gunpowder bag made by Zhao Lei and run towards the lump of cow dung with a jump. Gunpowder is buried in cow dung.

The bear kid took a small fire stick and lit it.

"One, two, three, run~~"

Bang!

Flying with.

Da da, smashed all over the bear children.

Then I only heard the king's hearty laughter from behind: "Hahahahahaha!" ”

Yangyang: ......

Bear Kid: ......
