Zhou Hei felt that he had put in enough energy.

But I didn't expect that even if the iron sheets were so thin, it was still useless.

He's tried it once before.

As a result, the bow string directly hung the burr on the thin piece, and the bow string was pumped on his face.

Zhou Hei wanted to try again today, but the result was still unsatisfactory.

Now that Zhao Chen has come, Zhou Hei has not explained it.

Zhou Hei felt herself suffering from Zhao Chen's trust.

"Take a look at the iron sheet." Zhao Chen and Zhou He said.

Zhou Hei handed a good iron film before Zhao Chen.

Zhao Chen held the iron piece and looked at the situation carefully.

Sure enough, when I saw the iron sheet, there were burrs everywhere.

This is an extremely common situation.

The burrs are like barbs, hanging on the iron sheet, and encounter something with slightly lower hardness.

It must be easy to break.

Such as bow string.

"Dean, this matter is not blame Zhou Hei. It is useless to be a subordinates. I can't think of removing this burr." Zhou Bai spoke to maintain his brother.

"Dean, in fact, this matter can't blame others. We have limited technology now, and there is no way to remove such a burr."

"Yes, Dean, if it were someone else, he might not have been able to do this."

The rest of the craftsman also said that it was necessary to maintain Zhou Hei.

Zhao Chen waved his hand and interrupted everyone.

He did not come to the teacher today to ask the sin, but to see what it needs to be solved by himself.

"The burr problem is not difficult to solve, I have a solution here."

"Director, do you have a way to solve this burr?"

"What is the way?"

"Dean, you can't fool us."

As soon as Zhao Chen's words fell, a number of craftsmen opened one after another.

They were anxious about this and didn't expect anything to do it.

Zhao Chen actually has a solution now?

This really makes them feel difficult to believe.

"I'll draw the file drawings for you." Zhao Chen said, then came to the table beside him, picked up the paper and pen to draw on the paper.

After a while, a scalp drawing appeared in front of everyone.

"The file can remove small burrs."

"But there is still no way to completely change the situation of the bow string."

"I am here, it is the drawings of various types of steel balls. According to the steps above, do you make some steel balls."

"With these, even if the burrs are not completely cleaned, the bowstring can be avoided from being broken."

"By the way, this steel ball is very important, everyone is upset." Zhao Chen took out a drawing from his arms to explain Zhou Hei's hands.

Nympho

Back to the East Academy again, Zhao Chen saw Cheng Shimo.

He came over to tell Zhao Chen that everyone's training has made great progress in recent days.

So I want to ask Zhao Chen if I want to see it.

The ten days given by Zhao Chen, now only half of the past, Cheng Chu Mo was so confident.

Obviously, students' performance is better than Zhao Chen's imagination.

"No need, it's time that you agreed to."

"At that time, His Majesty and Bai Guan will come over. Don't get out of the chain." Zhao Chen patted Cheng Chu Mo's shoulder and said.

Cheng Chumo touched his head and nodded at Zhao Chen.

Zhao Chenzheng was about to explain something with Cheng Shimo again, and saw a eunuch running.

"His Royal Highness Han, Majesty has a purpose. Please ask His Royal Highness Han to enter the palace immediately. If you have any discussions," the eunuch came over and let Zhao Chen go to the palace.

Let myself go to the palace, and also say that there is something to discuss, which makes Zhao Chen feel strange.

Today, Datang is no longer a big deal, why is it a bit anxious today?

"I understand." Zhao Chen waved his hand and signaled that he understood.

After explaining a few words to Cheng Chumo, Zhao Chen left the academy.

The college has twenty miles away from Chang'an City.

When Zhao Chen came to the door of the palace, it was noon.

Zhao Chen has seen Wei Zheng who hasn't met here for a long time.

The old guy hasn't come to Zhao Chen once because of Li Tai's incident last time.

Now seeing Zhao Chen, the old guy glanced at the side, not looking at Zhao Chen.

Obviously this is the qi in the stomach that has not yet disappeared.

The emperor sat in the upper head and saw Wei Zheng's appearance, he just smiled.

"Zhao, is lunch available?" the emperor asked.

"No." Zhao Chen shook his head.

"No, then hungry first!" The emperor said with a smile.

This makes Zhao Chen slightly stunned.

He thought that the emperor asked himself to eat lunch, so he wanted to make himself eat here.

result……

"Seeing that His Majesty looks like this, is it very excited? Is His Majesty who will be a concubine again?" Zhao Chen rushed back.

At that time, Lao Li's face turned dark.

How old is he? Why do he still think about taking a concubine?

Besides, whether the emperor accepts a concubine is not something that a prince should say.

"Cough--" The emperor coughed awkwardly.

Looking at Fang Xuanling on the side.

Fang Xuanling knew what the emperor meant, and immediately went to Zhao Chen, and said in his hands: "His Royal Highness Han, Goguryeo's envoy came."

"Yuan Gai Suwen?" Zhao Chen frowned.

"It is King Goguryeo, Gao Burning."

"They want to talk to me with me." Fang Xuanling and Zhao Chen talked about the reason why Goguryeo's envoys came to Datang.

Zhao Chen had long thought that Yuan Gai Suwen would send someone to discuss peace.

But what Zhao Chen is a little bit unclear is why Lao Li head looks so happy?

"Why does His Majesty look particularly happy?" Zhao Chen and Lao Li head asked.

The emperor froze, converging the smile on his face.

"Datang and Goguryeo fought, and finally retired Yuan Gai Su Wenjun.

"Shouldn't this be happy?" The emperor said, looking at Zhao Chen.

"Fang Xiang feels it, should I be happy about this?" Zhao Chen looked at Fang Xuanling and asked.

Fang Xuanling secretly blew up.

This is clear that it is a difficult thing to be in trouble.

No matter how he answered, he would offend one between the emperor and Zhao Chen.

Zhao Chen asked this, apparently thought that this matter was not happy.

Following Zhao Chen's words, isn't that hitting the emperor's face?

If you follow the emperor, say that this matter is worthy of happiness, wouldn't Zhao Chen annoy him?

"Your Highness the King of Han, it is difficult for the ministers to know this for a while. They still have to listen to His Highness the King of Han's views before they can make an analysis." Fang Xuanling really had no choice.
