After leaving Guanyin Nu, Zhu Jun was still unsatisfied.

He went back to the study and wrote a letter, which was roughly talking to Wang Baobao and the others.

The best way to disintegrate the remnants of the Mongol Yuan was to log in to Yingchang and catch them off guard.

The Beiyuan relied on Gaoli's small sampan and could not stop Daye from going to the footsteps.

However, there are 100,000 elite soldiers in Yingchang, which is not so easy to break into.

Firearms have not been developed yet.

He knew very well that the most primitive black gunpowder formula was very good.

One nitrate, two sulfonates, three charcoal.

However, the power of a small amount of black gunpowder is just a big firecracker. It’s okay to scare people, but it’s really not easy to blow people to death.

Zhu Jun remembered those novels, using fist-sized pots to fill black gunpowder and killing all directions, which was simply delusion.

That kind of person can blow up and hurt people, but cannot kill people.

The ceramic splash is simply worn without any clairvoyance.

It’s okay to scare people, but it’s really not lethal.

Is grenades killed by explosions?

It is not, but rather it relies on splashing shrapnel to kill enemies within a certain range.

With today's medical technology, iron tablets enter the body and are disabled even if they don't die. Are you afraid of tetanus?

Are you afraid of suppuration infection?

But if you want to take the lethality of the grenade, the filled black gunpowder must reach a certain proportion. Otherwise, it will not explode at all, and even if it explodes, it will not collapse.

He suppressed his thoughts, and the production of black gunpowder is still very low now.

He needs more black gunpowder and needs to make more iron cans suitable for use.

It also takes countless explosion tests to make the stability of the weapon controllable.

In those novels, the plot of making black gunpowder and killing the world is simply stupid.

Even if it is a big sword that kills the enemy, it must be able to have strong lethality after it is opened.

The gunpowder workshop is in the mountains in the south, and the most core craftsmen are responsible for it.

A team of thousands of people is stationed there.

Li Jiba knew that he had transferred a core past, but he didn't know what was being studied inside.

Now he doesn't care about anything except leading troops.

It seems quite ruthless, but Zhu Jun is protecting him, leading troops and in charge of intelligence organizations. No matter how strong Zhu Jun is, he will not trust him easily.

Thinking of this, Zhu Jun had a solution. He wanted to give his three brother-in-law he had never met, a big gift!

......

In the blink of an eye, it was the end of October, and a steady stream of caravans entered Yingchang.

Most of the Mongolian Yuandu are very close to Yingchang, and they cannot even cut transactions between the two places.

So the border guards are also turning a blind eye to this. As long as they do not sell salt and iron, they will receive the benefits.

And it can also better inquire about the other party's information.

On this day, Wang Baobao was reading a book at home. It has been half a year since the new emperor ascended the throne.

In another two months, this year will pass.

Since he handed over the tiger talisman, he has been idle all day at home and has nothing to do.

Tuoyin Timur and Vajranu were also implicated and now they have nothing to do at home.

"Brother, Guanyinnu is coming again!" Tuoyintemur walked in with a thick letter, his face full of joy, and Naodu was still following him.

"Hurry, open the letter and see what my sister wrote!" Nailu said anxiously.

Although Wang Baobao intended to disconnect from Guanyinnu, he was also happy to see his sister's letter.

When he opened the envelope, he found that there were two letters in it, one written by Guanyinnu, and the other one was his cheap brother-in-law.

"Hey, Zhu Jun...isn't that my sister's new husband?" Nailu was stunned, "Why did he write a letter?"

"Do you think Guanyinnu has written a letter, but he doesn't know?" Wang Baobao snorted, read Guanyinnu's letter first, and was also very happy to learn that Guanyinnu was pregnant, "Okay, okay!"

Tuoyin Timur and Nailou were also very happy, "It's great. It seems that the Qin King was a soft boy before, no.

Still a new brother-in-law is amazing!”

Wang Baobao glared at Nailu and immediately looked at Zhu Jun's letter.

Zhu Jun's letter is quite long and polite. Although Wang Baobao went to see it with tinted glasses, he felt very comfortable.

"Brother, what is written in the new brother-in-law's letter?" Nai Du scratched his ears and his head anxiously.

"You can see it yourself!" Wang Baobao handed over the letter.

Nailu took the letter and read it with Tuoyin Timur.

"Ah, my new brother-in-law has prepared a meeting gift for the three of us brothers?" Nailu was stunned, "Where is the meeting gift?"

Tuoyin Timur said, "In the backyard, the sender pulled two carriages over. I hadn't had time to see what was inside!"

"It's more important to be a treasure!" Nailu said: "Let's go and see what the new brother-in-law has prepared. This guy is more sensible than the King of Qin!"

"Retreat!" Nailu was about to leave, and heard Wang Baobao say in a deep voice: "Are you not afraid that this is their plan? If the court knows that I have received the gift from King Wu from Daye, they may still arrange us!

Now is the critical moment, and any turbulence can kill us.

As long as you survive this year, will it naturally come to good luck!"

"Brother, that's our brother-in-law!"

"Our enemy won't think so!" Wang Baobao snorted coldly.

Tuoyin Timur felt that Wang Baobao was a little angry, "No one knew about this!"

"What if?" Wang Baobao said: "You have never seen any good things. Do you want to fold our family in because of these two cars?

You don't know that they have been looking for our handles.

They kept saying things about Guanyin slaves before. Don’t you remember them?"

As he said that, he took the letter from Tointemure and burned it directly. When the letter was turned into ashes, he said again: "Burn all the things in that car!"

Nailu wanted to refute, but she didn't dare, "Then let's see what it is before burning, right?"

"Yes, brother, look at the boss? It's my brother-in-law's new intention!" Tuoyintemur said: "My sister is pregnant now, it's a happy event. It's been a long time since we have not had a happy event!"

Wang Baobao knew that they were feeling uncomfortable staying at home these days. He hesitated for a moment and nodded, "Let's go, I'll go with you!"

The reason why he accompanied him was mainly because he was afraid that these two guys would not be willing to burn it and collect the things.

Once the news leaks out, these things can be sent to the West.

When I arrived at the backyard, there were indeed two carriages.

The donkey opened the curtain impatiently. There were several large boxes in the carriage. He and Tuoyintemur carried the boxes down in a few seconds.

"It's quite heavy, the things inside should be quite expensive!" Nai Du rubbed his hands and immediately opened the first box!
Chapter completed!
