Zhang Feng has nothing to hide.

After all, there is no secret about these things. As long as you master a certain proportion, almost everyone will make them, provided that you can get the saltpeter from the Ministry of work.

The most important thing is that after they have a look at these things today, they will give them the manufacturing and so on in the future. He doesn't have the spare time to focus on them.

The most important thing is.

Now Yu Shinan and other great scholars are staring at themselves. If they go on like this, in case these great masters give up the challenge, then... Zhang Feng will have to cry.

The cave is no longer a little big place on the edge of the cliff.

At this time, the cave, from the mountain path on the cliff that could only accommodate a carriage, directly developed into a large and flat field. There were several large earth stoves that didn't know what to do in the field, and a large fire stove burning without balls piled up with pieces of stones, making the whole field hot.

Among them, there is a cave, which is also decorated with a sense of luxury at this time,.

A big iron gate with seven characters written to the forging workshop of Bailu Academy.

It makes people look a little extraordinary.

At this time, at the entrance of the cave, the more than 30 craftsmen originally brought from the western regions stood on both sides with neat bows. After seeing Zhang Feng, everyone hurried to worship.

"Dean!"

Zhang Feng looked at the shock on Yuchi Gong's face. He couldn't help but feel a little tipsy, and the strength of the wine was a little weak.

He waved his hand and said, "Hello, everyone! Go busy. Come today, just look around, look around!"

"Come on, let's go in and have a look?"

While Zhang Feng was talking, he asked Li Yuan to be parallel with himself.

As soon as they saw it, they dared not do it again. They hurried into the cave with them.

Li Yuan has been longing for this cave for a long time.

But without Zhang Feng's permission, even Yu Shinan and others can't come in, which shows Zhang Feng's interest in this place.

Not to mention this cave.

As soon as they entered the cave, they saw the situation in the cave.

The wall of the whole cave is polished very smoothly, just like a living house.

Near the entrance of the cave, there are two big windows.

But at this time, it was sealed by iron bars and transparent glass, and the whole cave looked as bright as outdoors.

In the middle of the cave, there is still a large and long table. On both sides are countless forging tables and stoves. Next to the stoves are large and small hammers.

But at this time, these stoves seem to have made no fire for a long time.

There is no dry temperature in the air,.

On this platform, the people who went out to meet the crowd turned back and continued to sit in front of the platform, stirring up something.

There are big bamboo bobbins, a pile of wax, and small scales. Not to mention, there are oil paper sheets in front of these things on the left. In front of the oil paper, there are three large frames.

It emits bursts of unpleasant smell.

These people, from these boxes, carefully pick up some powder, put it in the scale, weigh it, and then mix it, etc.

Li Yuan really saw such magical things for the first time.

How could Yuchi Gong and others not be the same.

At this time, one eye stared big, like a gong.

The most important thing is that each of these people wears a white glove on their hands and a mask on their mouth.

This made several people more curious.

Looked around.

Zhang Feng didn't see any problems.

There is almost nothing wrong with the gunpowder ratio.

At this time, he couldn't help asking, "alchinnon, what happened when you said that the chamber was blasted?"

Smelling the speech, several people couldn't help looking over.

Alchinnon did not speak, but led Zhang Feng to a small stone chamber in the innermost part of the cave.

When you open the door, you can smell the strong smell of gunpowder smoke and several bamboo tubes on a shelf: "Madam President, according to your instructions, we sealed these gunpowder in small bamboo tubes in a certain proportion, but I don't know how to do it today. I took this thing to store it. I saw him smoking. It exploded before I went out far."

Hearing the speech, Li Yuan and others couldn't help staring bigger

Curiously interrupted the two and asked, "Feng Zi, can we talk about it first? Is this a gadget?"

"Yes, you always play charades. Is that good?"

Zhang Feng saw that several people were dissatisfied, so he waved and asked al Jinnong to take out some bamboo tubes from the warehouse and said, "this thing is gunpowder, the thing I said last time."

Gunpowder!

This thing seems to be really scary.

Zhang Feng said this thing the last time he fried fish.

But I haven't seen this thing since I said it. Today, are these people producing that kind of thing?

Several people looked at each other, looked at Zhang Fenghua entertaining al Jinnong and hurried to keep up.
