Jing Zhe waited on the street, and after a while, Han Han and Zhou Zhiwei came back with a bag of marijuana on their backs, just like refugees.

Saltpeter can understand more, after all, there must be no shortage of firecrackers there, and Jing Zhe gave Han Han a lot of silver, and bought it at a price higher than the market price, and others would definitely be willing to sell it.

But it was surprising that Zhou Zhi failed to bring back such a large bag of sulfur, could it be that the pharmacy was ransacked?

After asking, it was confirmed, Zhou Zhiwei didn't know how much to buy, so he simply bought them all, the little medicine boy didn't want to sell it, he was afraid that Zhou Zhiwei would do bad things with so much sulfur, but he heard that he was from Jinxi, and finally agreed.

"Okay, let's carry it home first!"

So, the two of them carried the sack bitterly and walked in the direction of the Jing family, Han Han is a practitioner, and it is not difficult for him to carry such a sack, but Zhou Zhiwei, a boy with fine skin and tender meat, was already tired enough when he came back from the pharmacy just now, and walked so long again, and when he came to the door of Jing's house, he sat directly on the ground.

This time, he didn't say a word, for fear that Jing Zhe would say that he "talked too much"...

"Brother Zhou, your physique is not good! How do you write calligraphy? ”

"Jing... Brother Jing, does writing calligraphy have anything to do with physique? ”

Zhou Zhiwei gasped and looked puzzled.

"Of course there is, it's easy to be jealous if the calligraphy is too good, beaten by someone, and the physique is not good, so you can't run!"

“……”

Jing family.

Zhu Xinning entered the palace and went to the court, and then went back to the Prime Minister's Mansion directly, while Liu Jinghong went to the camp of Jingzhou City to inspect the camp of the Jinghong Iron Cavalry, although when they were with him at night, Zhu Xinning and Liu Jinghong both showed the posture of a little daughter, but when they were outside, they were proper strong women.

This contrast is wonderful, and Jing Zhe also enjoys it very much.

asked Zhou Zhiwei and Hanhan to put down their things, and Jing Zhe issued an eviction order: "Brother Zhou, let's get here today, you go back first!" ”

“？？？”

Zhou Zhi, who is tired like a dog, can't help but put a few question marks.

What about those who say they are good at practicing calligraphy?

"Your physique is not good, go back and practice again, and teach you cursive after you practice!"

"Brother Jing, you don't need to practice your physique, after all, I don't love to be in the limelight as much as you, I'm just entertaining myself at home, no one will beat me, you better teach me quickly!"

But I was thinking in my heart, you love to pretend so much, haven't you been beaten?

"Well, that's right..."

I thought for a moment, "You come with me!" ”

As he spoke, he went out of his house again, came to the bank of the Yishui River, pointed to the vast and vast water surface and asked, "What is this?" ”

"This is Yi Shui!"

"Yes, then you just stare here, when you have an epiphany, come to me to teach you calligraphy!"

“……”

What kind of epiphany did this thing?

Seeing that he was puzzled, Jing Zhe smiled, looked at the lake and said: "There are three realms of calligraphy, one is that you are now, looking at water is water, the second is more advanced, it is called looking at water is not water, and the third is returning to the basics, called looking at water or water!" ”

Is it so complicated to write calligraphy?

Zhou Zhiwei looked at Jing Zhe and couldn't help but be in awe, no wonder he had seen some masters who had written calligraphy all his life not as good as Jing Zhe's writing, this was a poor realm!

It seems that this apprentice is really right, and when he succeeds in his studies, he will be able to show his might when he returns to Jinxi!

But he asked very curiously: "What kind of realm is Brother Jing?" Is it the highest level, looking at water or water? ”

Jing Zhe shook his head, "My realm is quite special..."

"That's whoever you want to get out of the water, whoever comes out of the water!"

“……”

……

After drying Zhou Zhiwei on the bank of the Yishui River, Jing Zhe went home.

First, let Han Han bring sulfur and saltpeter into the room, and then collected a lot of carbon from the firewood room, and carefully placed it on the table, the three giants of the gunpowder industry can be regarded as gathered!

When he was making ice in Bishan, he had the prototype of making black powder in his mind.

His original idea was to make some black powder for Lu Li, the huge power of black powder could completely allow her to keep it as a backup, and she didn't have to worry about the government encircling and suppressing Bishan again.

It's just that Su Mochen came forward later, Lin Wenyao's family ended up very miserably, and the newly appointed prefect also canceled the hunt for everyone in Bishan, so the plan to make black powder was put on hold.

Yesterday in the court, when he talked about the method of breaking the silver clothes, he thought about this plan again.

Undoubtedly, the fastest weapon to break the defense is black powder, because it is sensitive, flammable, very simple to operate, a little spark can be ignited, and at the same time the destructive power is extremely great.

When each unit volume of gunpowder is burned, the combustion temperature reaches more than 1,000 degrees Celsius, and the volume can expand nearly 10,000 times, causing a violent explosion that can destroy thousands of times the volume of buildings.

Therefore, Jing Zhe dared to bet with Qi Junguang that as long as there was enough black powder, the entire Southern Qi would be able to blow him up, not to mention just fifty silver wisp troops!

Moreover, if some sharp blades or other hard objects such as iron and stone are mixed into the gunpowder, when it explodes, the power exerted is like a shotgun, which can easily penetrate the human body and cause greater destruction.

As for how to make it, although he is not an engineering man, he still knows some about the original configuration ratio of black powder, which is nothing more than one sulfur, two nitrate and three carbon.

However, with the development of the times, this ratio has also been improved a lot, so he is ready to test it.

He first smashed saltpeter, sulfur and carbon into fine powder, and then according to a fixed ratio, asked Hanhan to find some bamboo tubes, make up numbers, load the raw materials, and add a long lead after the hammer was strong.

Because the raw materials are all ready-made, Jing Zhe has a production idea, and in less than half an hour, six black powder bamboo tubes with different proportions and different weights are ready.

At this time, Han Han knocked on the door.

"What's wrong?"

Jing Zhe opened the door and asked.

"Zhou Gongzi came back and said he was enlightened!"

“……”

Jing Zhe went out and saw Zhou Zhiwei standing outside the door with his legs crossed, high-spirited and proud.

When he saw Jing Zhe, he immediately smiled and said, "Brother Jing, no, I will have to call you Master in the future!" Just now, Master asked me to watch the gurgling water by the Yishui River, and I thought Master was making fun of me, but I didn't have a clue for a long time! ”

"But when I saw the confluence of the water and sky in the distance of the Yishui River, I suddenly realized! Look at the water again, and sure enough, it's still water! ”

“……”
