Zhang Feng was checking the materials brought by the three people at this time. He spread all the materials on the table, looked at them carefully, and muttered: "this is beef tendon, beef glue, horse glue, fish glue, rhinoceros glue..."

He nodded with satisfaction, but when he saw the horn, he frowned a little: "it's a pity that the horn is not white, but the cyan one is OK. It shouldn't be much different."

Cheng Yaojin on one side was a little anxious: "Fengzi, what's the difference between white and cyan?"

He doesn't want to make useless bows and arrows with the materials he has worked hard to get.

Zhang Feng took a look at the ox horn, then put it on the table and said with a smile: "it doesn't have much impact, that is, the white horn is harder, but the green horn is not bad. In comparison, it doesn't have much problem."

Cheng Yaojin was relieved. As long as the divine bow was not weakened, he hurriedly said, "can it be made now?"

Zhang Feng nodded and looked at alchinnon: "find five big pots, and then pour all these beef glue, horse glue, fish glue, rhinoceros glue and deer glue into the big pot separately. Add water and cook with a small amount of lime alkali until the water is dry."

Boiled dry?

Will you cook things without it?

Cheng Yaojin looked at Zhang Feng with some worry: "Fengzi, it's not easy to find this thing. You can't spoil it."

He didn't understand the process of making bows and arrows, but he always felt that it was a waste of materials.

Zhang Feng smiled and gave Cheng Yaojin a reassuring look: "don't worry, there's no problem."

Then he wanted to see alchinnon and said, "do it the way I just said."

Alchinnon nodded. He had no doubt. Anyway, what the dean said was right. Even if he ate beef glue, he thought it was right. So he handed it to his men and ordered a few words. Then he looked at Zhang Feng: "Dean, it has been ordered."

"How about the Tuomu I asked you to send?"

Zhang Feng thought of Tuomu and asked.

Alchinnon pointed to the outside of the cave and said, "Dean, the wood has been placed outside the cave and is waiting for the dean's order."

Zhang Feng glanced at the crowd and walked to the door: "go, let's go out and have a look."

Everyone followed closely. They didn't know the production process of bows and arrows. However, if you watch it today, you might learn something and use it in the future. In particular, Cheng Yaojin was holding the psychology of stealing teachers at the beginning. If he learned the production process at that time, he might be able to configure one for his subordinates.

When they came to the outside of the cave, they saw that hundreds of logs were placed here, all of which were Tuomu.

Zhang Feng glanced, showing a trace of satisfaction, and then looked at alchinnon: "go find some people, take a saw and divide the wood into three kinds. The first kind is 180 cm long and 8 cm wide, the second kind is 150 cm long and 5 cm wide, and the third kind is 130 cm long and 3 cm wide..."

Zhang Feng kept telling al Jinnong, but he didn't care. A sly look flashed in Cheng Yaojin's eyes.

Although he doesn't know the production process of bows and arrows, he knows that this wood is the main material of bows and arrows. These are common sense.

Now, Feng Zi said that these are the production process, or the most important production process. If he learns all these, he may be able to make bows and arrows in the future.

Originally, he came with the psychology of stealing teachers. Now Fengzi has no taboo, so he can speak better.

Thinking, Cheng Yaojin salivated and said to Zhang Feng, "Fengzi, why don't I go up to help?"

Zhang Feng looked at Cheng Yaojin in disbelief.

He knows that this guy is usually sneaky and lazy. Why did he take the initiative to help today?

Is it hard to find a conscience?

Or do you have another idea?

Chumo also looks at Cheng Yaojin with an unbelievable face.

If others don't understand Yaojin, can he not understand it?

I'm usually too lazy to move at home. Why do I want to help today?

He looked at Yaojin puzzled and was about to ask, but at this time, Zhang Feng spoke. He looked at Yaojin curiously and asked, "Yaojin, what's the matter with you today? Have you changed your sex?"

Cheng Yaojin smiled, touched the back of his head, and deliberately put on a very simple look, so that Zhang Feng couldn't see it. So: "that's not true, but I often don't move at home, and my muscles and bones are a little loose. It depends on your current exercise and some itching."

"Oh..."

Zhang Feng looked at Cheng Yaojin suspiciously. He still didn't believe it. However, since others have said so, it's not good to refuse. In addition, more people will have more strength and can do it earlier, so he nodded: "that's OK. Go and help them."

Cheng Yaojin nodded, but instead of looking for the workers immediately, he turned and looked at Cheng Chumo with a horizontal eyebrow: "boy, go, go sawing wood with me."
