In Yanhe Castle, the sound of pounding used to cover up had subsided. As for what Yanjiao was hit, no one knew, and Yanjiao didn't want to take it out.

Everything gradually calmed down and returned to its original state. However, occasionally people would mention the flying stones outside the sky. Some people speculated that Yanjiao had created a magic weapon, but they were just careful to hide it and were worried about being stolen. Some people thought that Yanjiao must have hit nothing, and might even kill the stone, but because of their face, they were not embarrassed to say it.

No matter how everyone speculated, Yanjiao remained silent, and even some Yanjiao warriors were curious, but seeing that the leaders did not have any intention of explaining it, if someone came over to ask, they would just keep a subtle expression at you, without saying a word, and just keep staring at you until the person who asked could not withstand the pressure and dared not ask questions again.

At this time, Zheng Luo, who was guarding the trading area in Yanhe Fort, and Duokang, who had just sent a group of ferocious beasts, was watching around the newly created knife in a room in Yanhe Fort. Zheng Luo also used a small copper pot in the room to test the knife.

Looking at the small copper pot divided into two, Zheng Luo was amazed. They now knew that in addition to bronze, there were other gold utensils suitable for making weapons.

"What kind of gold artifact is this? Shao Xuan said that the type used to be called copper, but what about this now?" Duokang asked.

Zheng Luo shook his head, "I don't know, but, speaking, the people who saw Shao Xuan in the past two days have gone to the secret room again?"

"He seemed to be thinking about something." Dokang was also puzzled.

Yanhe Fort underground secret room.

Shao Xuan stared at the results calculated in the past few days and circled one of the symbols with a pen, which was marked on the ring map of the Yi family before.

After breathing a sigh of relief, Shao Xuan rolled up the animal skin on the table, tied up all the other cloths used as drafts, and burned them when the time comes, he just needs to keep the final result.

Although the conclusion has been drawn, this conclusion is based on several hypotheses. If those hypotheses are true, then the result is true. The main component of the crystal core knocked out of the crystal stone should be iron.

Although Shao Xuan had long believed that the metal alloy belonged to iron, he could not draw a conclusion because he had no theoretical support. Now, Shao Xuan was convinced a little bit.

“Iron tools…”

Shao Xuan sat at the stone table, beating his fingers at the table, thinking.

The existing iron smelting technology is limited, otherwise copper ware would not be popular. Even the Gongjia family, which is famous for casting, is basically mainly copper ware. It can be seen that the smelting of iron ware is not that simple. Shao Xuan has no choice. He is not a professional talent. Moreover, due to the nuclear species in this world, there are many special things. It must be implemented according to the existing situation.

However, Yanjiao people really don’t have much talent in this regard. They were too late to get in touch with them, and some of their thinking has been fixed and their foundation is poor. It is too difficult to make achievements in this regard. New talents are being cultivated, but this takes time.

Shao Xuan was thinking. Duo Kang came over and called him.

"What's the matter?" Shao Xuan asked, moving the stone gate away.

"Someone is looking for you." Duokang's face was serious.

"who?"

"The Changle people."

The person in Changle?

Why is it coming again?

Haven’t Wuhe released them as agreed? And Wuhe and others are much more honest now, and the Yanjiao people did not arrest them.

No matter what, there is something abnormal about this. The other party called Shao Xuan, which made it even more confusing.

When Shao Xuan entered the room, he saw the person sitting there with a "I'm not happy" smell. The other party didn't look strong, even a little thin, with sharp eyes like a knife. When Shao Xuan came in, the eyes he looked at were like a knife scraping back and forth.

There is no murderous aura, but this kind of person who almost wrote "impatient" on his face shows that the person is in a very bad mood at this time, otherwise he would not have acted like this.

Shao Xuan was stunned at the door and came in, ignoring the other party's eyes like shaking the knife, dragged a chair and sat down, "I didn't expect that Changle's leader would come here again."

This person is Su Li, the leader of Changle. His name was Wuhe later told Shao Xuan that the last time because of Wuhe, Su Li came here and responded to the conditions for delivering the letter proposed by Yanjiao. Unexpectedly, he came again this time. If he wanted to grab the things, he would definitely not appear here so openly, and even called Shao Xuan.

Hearing Shao Xuan’s question, Su Li sprayed an impatient "hum" from his nose, "Do you think I want to come here?!"

Because I had seen it before, Su Li didn't have to determine his identity. He took out his clothes, took out a cylindrical bronze ware, and then threw it towards Shao Xuan, "For you!"

Duokang and Zhengluo wanted Shao Xuan to be careful. Changle's people would not believe it, so beware of fraud.

Seeing the reactions of the two, Su Li sneered, but said nothing.

Shao Xuan took the cylinder and looked at it. He saw some cirrus-shaped patterns at the cylinder interface, and his eyes flashed with surprise.

"I think you should recognize whose thing this is." Su Li stood up, "I'll bring the thing and leave!"

Their Changle people should have been free and easy and had fun everywhere, but when did these people start to treat their Changle as sending letters across the sea?

Yes, it’s these Yanjiao people who started their heads!

This wind cannot last!

But he could not refute the reasons given by the person who delivered the letter every time. He was so frustrated. The last time it was because Wuhe was the little bastard who was dragging his feet, but this time it was because he owed Gong Jiaheng a favor. Gong Jiaheng had created a handy tool for him, but Gong Jiaheng didn't ask for any money at that time, but he just said that he would ask Su Li to do him a favor when needed. Unexpectedly, it was actually a delivery!

As the leader of Changle, although he did a lot of things that were angry and resentful, he still had credibility and had to do it if he agreed. So he came with something that Gong Jiaheng gave him.

It was because of his anger that Su Li did not have a good face when he came here this time, and he hurriedly left, fearing that Yanjiao Ren would also propose a delivery condition that he could not refuse.

Before Shao Xuan could speak, he saw Changle's leader swaying and slipping out of the window like the wind. When Duo Kang looked out, he saw only a long-winged bird in the air that was quickly away.

"What exactly is this? Who asked him to send it?" Zheng Luo walked over to look at the cylinder in Shao Xuan's hand.

"Gong Jiaheng." Shao Xuan looked at the cirrus cloud patterns on the cylinder for Zhengluo.

The cirrus-shaped patterns were not drawn at will. This is equivalent to a secret code of the Gongjia family. The hidden information is hidden and difficult to fake. The leader of Changle did not have to work hard to make fake patterns and sent them all over the place. Moreover, the creation of this cylinder was very exquisite and should have been made by the Gongjia family.

Twist the cylinder and put a scroll inside. The fabric is more exquisite and has the style of a royal city.

After opening the scroll and looking at the content written in it, Shao Xuan knew what Gong Jiaheng meant.

Here, Gong Jiaheng briefly explained the situation on the royal city. The general idea is that because of the delicate situation on the desert, Wang Ziji took the throne with great force and eliminated the opposition forces. Gong Jiaheng didn't say much about the specific situation on the royal city. His focus was that among those who were to be cleared, there were those he wanted to help.

Because Gong Jiaheng made great contributions to casting swords for Ji, Ji Fang promised him to exile those who were not involved in it. Now the situation is chaotic. Gong Jiaheng is worried that the exiled will be threatened by others. Don’t let those people come to the mainland here, at least they can do better with their casting skills and have a new beginning.

To put it bluntly, Gong Jiaheng's meaning is: these people are all technical, not political, they are not so conscientious, they are all rare talents, but they are just excluded because of the new situation in the royal city, and may even lose their lives. Do you accept these people?

Nonsense, collect! Of course!

Shao Xuan happened to be short of ironwork. The people who Gong Jiaheng could come forward to maintain the situation must be good. After all, Gong Jiaheng was not very friendly to the people from Gong Jia's family, but he cherished his talents, and those who could be valued by Gong Jiaheng would not have many bad thoughts.

Gong Jiaheng said that the route those people took was on the desert, avoiding the war center, but I don’t know if they would pass through the desert smoothly. If Shao Xuan had the intention to receive people, he hoped to go to the desert to pick him up.

Inside the cylinder, there is also a small copper ellipse ball, half the size of the fist.

When I opened the ball, there was a curled flying insect that looked like a bee, but it was somewhat different from a bee. The membrane wings were longer than the body, but they were also soft and flexible, wrapping the body when the body was curled up.

According to Gong Jiaheng, these flying insects have extremely sharp sense of smell and are similar to nasal sensations. They are trained to track them. When the surrounding environment is not enough to survive, they become a state of false death. They will not escape from the state of false death until the surrounding living conditions are restored. However, there is also a time limit for false death, at most one year, and some will be very short, which varies depending on individuals.

Not long after Shao Xuan opened the ball, the flying insects in the fake death state began to move their feet. Shao Xuan quickly closed the ball again. He has not started tracking yet, so he can't let the flying insect come out. Moreover, it's far from the desert, so it's useless to release it. What should I do if I can't run away? Shao Xuan didn't know what it ate, and Gong Jiaheng didn't say it, probably forgot.

Wait until the desert before letting it go.

"Shao Xuan, what are you planning?" Zheng Luo also read the content above. To be honest, he was also moved. He was from the Gongjia family. If it weren't for such a situation, they wouldn't have had this opportunity. But the desert is said to be quite dangerous. Is this worth the trip?

Shao Xuan put the scroll into the cylinder, and the small ball was also placed in, covering the cylinder.

"Go, of course, we are also short of casting people in Yanjiao, especially the birth of new goldware. It is difficult to develop more with us. Professional matters should be left to professional people, which is more efficient. Besides, I have planned to go to the desert recently."

His decision was not just because of Gong Jiaheng's letter, nor was it just the weird people rumored in the desert, but because he felt that there was something going on with the sapphire. (To be continued.)
