Chapter 1977

Cheng Yaojin was stunned.

There seems to be nothing wrong with that.

The bow and arrow have just been finished. If you pull it like this, you might be wasted?

Is Feng Zi praising his strength or damaging his bow and arrow?

After thinking for a while, he still didn't come out first. However, he still agreed with Fengzi's words and said, "you're right. I'm so strong that it must be bad when I pull..."

At this point, he turned his eyes to Chumo and said, "I have so much strength that you can't even pull away a bow and arrow. What's the use of you?"

While he was talking, he slapped Chumo. Chumo was scared and screamed, but he didn't dare to dodge, so he had to look at Zhang Feng for help.

When a hot look swept over, Zhang Feng naturally understood that he didn't want to save this guy, but when he thought about making a bow and arrow, he had to persuade: "Lao Chen, come on, it's not iron bull's fault that the bow and arrow can't be pulled open. There are important things that haven't been installed."

Hearing this, Cheng Yaojin seemed to be interested. He also stopped his action and asked with a smile, "what else do you want to install?"

When Zhang Feng saw Cheng Yaojin stop, he didn't pay any attention. Instead, he looked at al Jinnong and said seriously, "take out two slender steel pipes. The specific length should be installed between the bow handle and the bow string."

Alchinnon frowned slightly and had some doubts in his heart, but he didn't intend to open his mouth. Instead, he glanced at the bow and arrow, estimated it, turned and left.

If Cheng Yaojin was unwilling, he asked, "Fengzi, what are you going to do?"

"Wait a minute, you'll know."

Zhang Feng didn't intend to explain more. He waved and was impatient. He seemed to think of something again and continued: "you can't continue to fight the iron bull..."

As soon as he said this, Chumo looked at Zhang Feng as if he were a reborn parent. If he were a woman, he could hardly wait to make a promise. On the other hand, what kind of shit brother was Chang sun Chong and others?

When Dad beat himself, he didn't even dare to fart. It's still reliable.

Thinking, his eyes looking at Fengzi became more hot and grateful.

However, Zhang Feng's next sentence surprised him.

"If you want to fight the iron bull, go home and fight slowly. Don't make the forging workshop's blood thorn Hula..."

This

Chumo cries.

He thought Fengzi had found his conscience.

I'm going to plead for myself.

As a result

As a result, this guy is afraid of Yaojin beating himself on the mountain.

He wanted to cry, but he couldn't cry.

I couldn't help but look at the dead father.

Cheng Yaojin would give Zhang Feng a look that everyone knew. He said with a smile, "I understand. If you don't fight, leave some face for the boy first."

As soon as the voice fell, alchinnon also came back. He held several steel pipes in his hands, with different thickness and length.

"Dean, I've brought it back. What do you think of using it?"

Zhang Feng took one of the steel pipes, carefully checked it, looked at the people and said, "Lao Cheng, these two steel pipes are tied to the two pairs of bowstrings, and the other end is facing the bow handle."

Cheng Yaojin is a little silly.

Why is a steel pipe tied to the bow string?

Although these two pairs of bowstrings are not as powerful as the main bowstring, how can we tie a steel pipe?

This has never been done before.

He asked, "Feng Zi, what's your operation? Why should you tie a steel pipe?"

"Increase pressure."

Zhang Feng solemnly replied and looked at the bow and arrow: "don't look at the three bowstrings. In fact, they all work together, so the pressure will gather together. The role of this steel pipe is to disperse the pressure, and then the three bowstrings work together. When the pressure increases, the power will increase at the same time..."

Some of the people heard that their heads were big.

Especially Cheng Yaojin, he doesn't know anything about pressure.

I just want Feng Zi to explain the use of this steel pipe, OK or not.

As a result, the guy talked a lot and didn't seem to want to stop, which made his skull big.

He quickly waved: "stop, stop, Feng Zi, we can't understand what you said."

"I didn't expect you to understand."

Zhang Fengbai glanced at Cheng Yaojin. He didn't intend to say anything, but the guy asked. Well, let's talk about it. Moreover, he didn't listen to Lao Jin, because he knew that this guy must not understand, so all these things were told to alcinnon. This guy also looked righteous. He said: "These things are too profound. You can't understand them. Now start working."

With that, he glanced at the crowd. Finally, he looked at Cheng Yaojin and said, "Lao Cheng, these two steel pipes are tied to the two pairs of bowstrings, and the other end is facing the bow handle."

Cheng Yaojin gave a cry. He didn't know whether he had just been taught a lesson or what. This time, he didn't ask questions and started to work.

Soon, the steel pipe was fixed. He looked at Zhang Feng: "Fengzi, what should I do now?"
