Cheng Yaojin was angry when he heard this. He didn't mean well with the old thief. He wanted to get good things to his son. Although he also admitted that his iron ox was not competitive, he always felt a little uncomfortable when let others say it. Not to mention being an official once, especially this man had to rob the benefits of his son? He was furious for a moment, and his eyes stared: "what did you say? Why can't my iron cow? Make it clear."

As he said this, he clenched his fist and made a plan to beat his eldest son Wuji. Seeing that Li Shimin was broken, he quickly came forward to hold Cheng Yaojin and shouted, "Lao Cheng, what do you want to do? Don't you stop?"

Cheng Yaojin seemed to be Li Shimin, and his anger immediately disappeared. He stared angrily at Chang sun Wuji, and then pushed aside.

After calming the war, Li Shimin looked at Zhang Feng and asked solemnly: "Fengzi, then you continue to say what you just said. It's not important to hand it over. How to develop it is the most important. Tell me the way."

Zhang Feng nodded and said solemnly, "in fact, this film is not difficult. It is a plastic product, and plastic can be made of resin. There are forging workshops. First dissolve the resin with fire, then dry it, and lay it into thin and thick things similar to paper."

Hearing this, Chumo probably understood, because he saw the resin dissolution process with his own eyes. He said excitedly, "Fengzi, I know. Is it similar to the composite bow made at that time?"

"It means almost."

Zhang Feng smiled bitterly and said, "but you have to lay the resin very thin."

Chumo gave a sound, then bowed his head and stopped talking.

"Feng Zi, our iron ox has a good understanding."

Cheng Yaojin hugged Zhang Feng and slapped Zhang Feng on the shoulder.

Zhang Feng had to smile bitterly and responded most. In his heart, he secretly said that his mother can understand it. Is he a good iron bull? I don't know where the face comes from?

"Feng Zi, since the iron bull knows, will the task be handed over to the iron bull?"

Li Shimin glances at Chumo, then looks at Zhang Feng and says.

"Good."

Zhang Feng nodded. Now Chumo is the only suitable task.

But the eldest sun Wuji was a little unwilling. He stepped forward and stared: "no, what about our insects?"

Zhang Feng shook his head. There was really no way to take this guy. He had to come out and intervene in anything. He had to say, "I have arranged other tasks for insects and big cakes. If you don't believe it, ask them both."

Changsun Wuji looked at changsun Chong suspiciously. Changsun Chong said timidly, "Fengzi said let's make a steam engine."

After hearing this, sun Wuji's competitive heart barely calmed down.

"Well, now that it's all arranged, it's all right?"

Zhang Feng glanced at the crowd and saw no response. Then he said, "if it's all right, go back to the house?"

Li Shimin nodded, turned and walked to Zhang's house, followed by the crowd.

When they returned to Zhang's house, they drank another meal of wine. Li Shimin and others left.

Zhang Feng was a little sleepy and wanted to sleep, but he knew he couldn't sleep now and had to see Zhang Yuyao's parents, so he shouted at the door: "Lao Du, go and prepare some gifts. I'm going to Zhang's house."

As soon as the voice fell, Du Wisteria ran in. He looked at Zhang Feng suspiciously: "Sir, you're going to Zhang's house? Do you want to call Miss Yuyao?"

Zhang Feng was stunned.

I didn't think of this when I talked with Li Shimin and others just now. Now Lao Du reminds me. If there's anything wrong with Zhang's house, it's still up to Yu Yao.

Thinking, he nodded and said, "then call Yuyao."

Du Wisteria nodded and left, and came back in less than a moment, but he said with an embarrassed face: "Sir, some servants said that Miss Yuyao went out just now. I don't know where she went."

"Out?"

Zhang Fu looked puzzled. Where can Yuyao go? Is it difficult to go shopping? Or did you go home? After thinking about it, there was no answer. He waved and said, "forget it, since she's out, I'll go alone."

With that, he turned and walked outside the house, while Du Wisteria went to prepare gifts.

Zhang Feng waited at the door for a moment before Du Wisteria brought the gift. Zhang Feng got into the carriage and drove directly to Zhang's house.

Within a moment, the carriage stopped at the door of Zhang's house.

Zhang Feng got out of the car, adjusted his clothes, and led the servant carrying the gifts to Zhang's house.

"Good uncle."

All the servants of the Zhang family bowed down.

"Good, good..."

Zhang Feng replied awkwardly. In fact, he didn't like the title very much, but since he was engaged to Zhang Yuyao, the people of Zhang's family called uncle when they saw him. At first, they were really shocked. Later, they gradually got used to it, but they didn't come for a long time. They didn't feel accustomed to it.

"Uncle, are you here to visit my master?"
