Chapter 1589

Outside the cave.

The people carefully saw the shape of the bamboo tube,.

The bamboo tube is very similar to the one used to hold beer. Even people seriously doubt that this thing is actually the bamboo tube

But the bamboo tube was covered with a thick layer of oil paper, and there was a green thread outside.

It's all dripping with wax.

Seeing this, people couldn't help wondering more.

"Feng Zi, is this the gunpowder?"

Li Yuan stepped forward, completely ignoring Wei Zheng and Fang Xuanling, and his face was pale with fear.

Zhang Feng nodded and said, "yes, this is gunpowder. Would you like to try his power, old man?"

"No!"

"Feng Zi, you can't let the old man come!"

"Old man, Fengzi's goods are a pit. You must not believe Fengzi's words!"

Zhang Feng couldn't help rolling his eyes.

He said loudly, "this thing is actually just a large firecracker. If you really add some other things, hey, do you think the just blasted chamber is his power?"

"Come on, Lao Yu, I see that your face leaks red light. It seems that great luck is coming. Why don't you come?"

Yuchi Gong is not so stupid.

At this time, Zhang Feng thought of him, there must be fraud.

At this time, pretending not to hear, he whispered around Wei Zheng's neck, leaving Zhang Feng with a back that I didn't have time.

Zhang Feng smacked his mouth and sighed in his heart.

Nima

Counsellor.

Let Li Yuan come, he really dare not.

It's mainly to arouse these two goods, but these two deliveries are just masters of thunder and no rain. They are thieves.

He had to kiss his mouth and ask alchinnon to bring a big steel pipe to experiment with this thing.

Several people looked at the thick steel pipe at the mouth of the bowl, and their eyes were colorful.

Zhang Feng didn't say a word either. They sealed this section with alchinnon. The East steel pipe with a mouth at one end was aimed at a big tree almost a hundred steps away.

After drawing for a while, Zhang Feng carefully took out the fire fold.

This time.

The people who were bored to doze off came to the spirit and hurried to look at Zhang Feng.

Zhang Feng looked at the crowd with pity.

Without saying a word, he lit the lead of the firecracker in the trembling alchinnon's hand, quickly threw it into the steel pipe, and then they squatted in place with their ears covered.

"This..."

"Boom --!"

Don't wait for Li Yuan to ask.

moment

A sound that could pierce everyone's eardrums made Li Yuan stagger and squat on the ground.

Yuchi Gong and others are not feeling well.

This suddenly came. At this time, the people only felt that it was dark in front of them, and several people were stunned,. Stupid.

Looking at a big tree that was blown into powder by lazy waist not far away, everyone was dumbfounded.

Just that moment.

Several people only felt a loud noise, plus a trembling vibration, and then there was a fire in the thick and thin thing at the mouth of the bowl!

Yes, it's fire and.

Then, the tree became what it is now in the eyes of everyone.

Then there was smoke all over the sky.

smoke of gunpowder.

Bring a few people back to life.

At this time, there was no sound of air-conditioning

Everyone looked at Zhang Feng with a confused face, and then looked at the big tree burning slowly in the smoke. His scalp couldn't help feeling numb.

Is this the power of gunpowder?

This

What the fuck would happen if it were on the battlefield?

"Feng... Feng... Feng Zi, is this the cannon you said? This is gunpowder?"

Zhang Feng felt comfortable at this time.

Put your hands in your waist and light a flue: "yes, this thing is the gunpowder I said, but today is also the first time we see the test product. As for the finished product, it's still early!"

"No, I mean, we've all seen this artillery battle, but why is it so powerful when you get it in a bamboo tube?"

"Isn't this somewhat unreasonable?"

Yuchi Gong calmed down at this time, approached the exploded steel pipe, which was still smoking black, looked at it and kicked it, and said, "Feng Zi, you say, why is this thing so powerful?"

Zhang Feng groaned twice, "don't you understand?"

"This thing, to put it bluntly, is a combination of air pressure and aerodynamics."

Several people heard the speech, and a black line hung on their forehead.

"My mother, can you talk well?"

Yuchi Gong looked black and stared.

Zhang Feng smiled and shook a finger for a long time before he said, "want to know? Go back and ask your son!"

“……”

"I fucking..."

Yuchi Gong finally couldn't help it.

When he went up, he pressed Zhang Feng on the ground.

But at this time, Yu Shinan is coming with Chumo and others in a hurry.

I just saw this scene.

He roared from a distance, "Yu, stop the fuck!"

“……”
