Three Kingdoms, I open a tavern in Xudu

It turns out that Cao Cao also had this idea, and Chen Yang just brought it up, and the hero sees the same thing.

"After we got the horseshoes and stirrups, the strength of the cavalry has been enhanced, and they performed very well in the conquest of Yuan Shu."

Cao Cao expressed his thoughts and said: "Therefore, if the conquest of Yuan Shao is successful this time, I will unify the north and truly form a team of extremely powerful cavalry, and this cavalry can only be our Cao family. The general will personally command and only obey my orders!"

In this way, it was correct. The historical commanders of tiger and leopard cavalry were Cao Zhen, Cao Xiu, and Cao Chun, which conformed to the history Chen Yang knew.

Hearing him say this is also to prepare for Cao Ang later.

Chen Yang said: "The prime minister is also far-sighted."

Cao Cao laughed and said, "I'm not as good as Zi'an when it comes to foresight. You've already thought about the cavalry."

The two chatted and laughed, and soon arrived at the place where the three-bow bed crossbow and thunderbolt chariot were manufactured in the barracks.

"Prime Minister, my lord!"

When Ma Jun and the others saw this, they immediately stopped what they were doing, turned around and said respectfully.

Chen Yang nodded and said, "Others continue, Ma Jun, come with me!"

When he came to Cao Jun camp this time, apart from mentioning to Cao Cao that he wanted to establish a tiger and leopard cavalry, his other purpose was to find Ma Jun.

Under the leadership of Chen Yang, they went to an empty place in the barracks together.

Cao Cao asked curiously, "Zian, do you have anything good to show us?"

Chen Yang didn't speak first, he raised his hand.

Seeing this, Wang Yue took three big bags from his body and put them in front of Chen Yang.

After Chen Yang opened it, Ma Jun looked at it for a while and said, "Is it charcoal, sulfur and saltpeter inside?"

Sure enough, he was a great inventor of the Three Kingdoms, so he could recognize these things so quickly. Chen Yang nodded and said: "That's right, although these things are common, they are also very useful!"

Cao Cao couldn't see the use, so he asked curiously, "What's the use of these things?"

Chen Yang divided these three things in proportion, and then said: "You will know what it is useful for later, but I don't guarantee that it will be successful."

As he said that, he asked the soldiers to find some tools, first mix and grind charcoal and other things according to the proportion, and finally put them in the wooden tank for stirring, and fully mixed the three kinds of powders together to form a pile of dark powder.

After finishing this step, Chen Yang poured it on the ground, and said again: "Prime Minister, ask someone to fetch a torch, then let's stay away and light these powders on fire."

Ma Jun knew that Chen Yang's ideas could be unconstrained, so he studied the powder in front of him curiously.

Cao Cao didn't understand what this meant, but he did as he did, and asked a soldier to bring a fire bag to ignite the black powder.

But no matter how the soldier ignited the powder, the powder remained unchanged, which made Cao Cao feel even more confused.

"Zian, did the thing you want fail?" Cao Cao said.

"It did fail, but it doesn't matter, we have more raw materials, I will try again!"

Chen Yang continued to toss those things, and made a new portion according to the new ratio.

This time, he did it more meticulously, but he still failed in the end.

In desperation, Chen Yang began to match the third one. After learning from the previous two failures, it took almost half an hour to complete the third one.

"You try again!"

Chen Yang poured the powder on the ground, glanced at the soldier who lit the fire just now, and continued: "Pay attention to safety, it will be ignited later, you have to run faster."

The soldier was baffled when he heard this, thinking that these powders could really be ignited?

However, he didn't take Chen Yang's reminder seriously, picked up the torch and lit the powder, at this moment...

boom!

A dazzling flame suddenly appeared in front of their eyes, and then bursts of unpleasant pungent smell filled the air.

"Prime Minister be careful!"

Dian Wei and Xu Chu thought that there was some danger, so they stood in front of Cao Cao immediately.

Chen Yang was also startled by the fire, and soon he recovered, and murmured: "It really succeeded!"

At this time, the soldier who was going to light the fire sat down on the ground. He didn't pay attention to Chen Yang's reminder, so his hair, eyebrows, etc. were almost burned. Fortunately, the power of the powder was not strong, and others were fine, but they were scared all over. trembling.

"Old Xu, take him down to rest for a while!" Chen Yang pointed to the soldier.

Xu Chu dragged him down.

"Zian, what happened just now?" Cao Cao finally came back to his senses, he asked in shock.

"The powder just now is called gunpowder!"

A long time ago, Chen Yang thought about making thermal weapons. He couldn't make modern firearms, but it's not a problem to make a few explosive things with gunpowder.

As for how to do it, Chen Yang still remembered the recipe.

Therefore, Chen Yang said again: "But the effect of gunpowder is not only that, I will make another one for you to see."

After finishing speaking, Chen Yang started immediately and made another copy. This was already his fourth proportional ratio, and he was even more proficient in doing it.

In addition, he wrapped the finished gunpowder with paper, pressed it tightly, and used cotton threads as leads.

"Don't be too surprised later!"

Chen Yang smiled confidently, and he picked up the torch to light the fuse.

"Shopkeeper Chen, let me come!"

Dian Wei was worried that Chen Yang would be in danger, so he quickly grabbed the discount.

That being the case, Chen Yang was not polite, and took several steps back after handing it over to Dian Wei.

Dian Wei lit it, and he quickly backed away.

boom!

At this time, a deafening sound resounded in the open space, scaring Cao Cao and the others into a stupor, and they could not recover for a long time.

"Shopkeeper Chen, what are you? It's even louder than thunder!" Dian Wei said in shock first.

"Is the thing made of gunpowder capable of killing?" Cao Cao immediately thought about military affairs, and he asked expectantly.

"If it can be used properly, it will be easy to open mountains and crack rocks!"

Chen Yang nodded, then his eyes fell on Ma Jun, and he said: "Did you see it clearly just now? How to figure out this gunpowder will depend on your efforts in the future, but you must remember that this thing is extremely dangerous. There is a little spark!"

Hearing Chen Yang's words, Ma Jun fell into deep thought. After a long time, he said: "This subordinate understands!"

"It can open mountains and crack rocks!"

Cao Cao said excitedly: "Is this thing really so powerful?"

Chen Yang nodded, but he said again: "I still want to remind you to pay attention to safety when making it. This thing is like a double-edged sword. It can hurt others as well as yourself!"

Next, Chen Yang taught Ma Jun how to make and use the method.

Then, he left the barracks with Cao Cao and went back to Xudu.

As soon as he got near the city gate of Xudu, Cao Cao, who was riding on his horse, suddenly groaned in pain. His body shook, and he was about to fall off.

"Prime Minister!"

Chen Yang was about to catch him, but Xu Chu moved faster and had already caught Cao Cao and put him on the ground.

Several other guards immediately surrounded them.

"It's not a problem, my head is blowing up again!"

Cao Cao frowned, and he took out a jade bottle from his body, which contained several pills.
