Qin Chuan also saw this earlier, but he didn't say anything to remind him, the old guy had deliberately made things difficult before, and this time he wanted to see his jokes, he deserved to have this catastrophe, and he had to say that someone was getting more and more eager to repay him.

After a long time, Wang Yiyuan's eyes completely returned to clarity, he didn't say anything, just glanced at him, and then left without looking back.

"Brother Qin, you have offended Old Man Wang this time!"

"How did I offend him?"

Dugu Xinyue opened her mouth and found that it was really not good to force the responsibility on Qin Chuan, which was the same as complaining about the thatched house when she couldn't pull the, and complaining about the chef when she choked on eating.

Two days later, a powerful news spread throughout Longjiang City, Luo Hong and Liu Xianlong, who were clamoring everywhere, were slapped twice by Wang Yiyuan, and the reason given was that they were not self-sufficient, and they were not qualified to argue with others at all, and beating them was to wake them up, so don't be embarrassed!

The apprentice was beaten, and the master naturally wanted to ask for an explanation, so Yu Youde went to Wang Yiyuan to theorize, but after half a day, he came out with a gloomy face, and returned to his residence and immediately announced the retreat.

What happened to make the apprentice be slapped in the face, and the master still had to swallow his anger? Everyone wanted to find out, Jia Chaozong went to Yu Youde to eat a closed door, and then went to Wang Yiyuan, and was severely reprimanded.

Some people can't help but think of another party, the somewhat mysterious refiner, but there are not many people who know this person, and the Crescent Moon Princess who knows the inside story always looks secretive, these people are tormented by curiosity, but they are helpless.

Qin Chuan thought that he could finally be quiet, but who knew that a few days later, Wang Yiyuan came to the door again, "Little Qin Daoyou, I hope you can tell me the secret method of synthesizing dark iron, I can pay any price!"

Seeing that the old guy's face is haggard, it seems that he has not been doing well for a while, and since this so-called secret method of synthesizing dark iron has come out, it is difficult to keep it, and maybe it will cause trouble because of it, so it is better to send it out as soon as possible to exchange for something affordable, and at the same time save this old guy from hating himself.

"Then tell me what price you can pay!"

"I can give you my cultivation experience of studying refining weapons for eight hundred years, and at the same time owe you another favor!"

"Hehe, Senior Wang is too polite, then I will be disrespectful!"

"You really agreed?" Wang Yiyuan couldn't believe his ears a little, in his mind, like this kind of secret method, the other party would definitely bite to the death, and he couldn't say that he had to give up his old face to coerce and lure, and then bleed heavily to achieve his goal.

"Why don't you agree, it's useless to keep it in my hands, it's better to give it to the seniors, maybe one day you can really apply this method!"

Seeing that Qin Chuan directly took out the jade slip and threw it over, Wang Yiyuan had nothing to say, people had long expected this day, and he was really a villain, but he still couldn't wait to take the jade slip.

The synthesis of dark iron is really simple, the key is to refine silica and coke, and then determine the proportion of materials, Wang Yiyuan just glanced at it and already knew it in his heart, but for fear of being deceived, he decided to experiment it himself.

After a few hours, he successfully synthesized a piece of dark iron, looked up to the sky and laughed proudly, and the gloom of several days was finally swept away, until he had a feeling like a man on his back, and then he found that Qin Chuan was staring at him resentfully.

"Ahem... The old man has lost his temper, this is my life's work in studying refining, I hope you can inherit my alchemy skills, and you will be blue!" "Thank you seniors!" Qin Chuan solemnly performed the half-master salute, and then took over more than a dozen thick jade slips.

Wang Yiyuan saw that Qin Chuan's gaze softened a lot, and gladly accepted his gift, but the next sentence made Qin Chuan almost go berserk, "Since you and I have set the status of master and apprentice, then the second question you raised, the method of separating gold, silver, copper and iron, should we explain it to the teacher?"

Damn, this old fellow, you have to inch in!

......

After a long time of talking, he finally sent Wang Yiyuan away, and then picked up Wang Yiyuan's refining experience and studied it.

It took a few days to read more than a dozen jade slips, and secretly said in his heart that this exchange is really not a loss, although the refining treasure book is brilliant and profound, but it is mostly purely theoretical, and Wang Yiyuan's refining experience is a detailed record of the refining process again and again, there are successes, there are failures, and afterwards it was analyzed and summarized, such things are precious for a novice refiner, relatively speaking, Lei Wannian and Fei Changgong's refining experience is too rough.

With theory and practice, Qin Chuan's refining level is improving rapidly, and in the sixth month after he came to Zhongzhou, he finally succeeded in refining a high-grade flying sword, which means that one foot has stepped into the threshold of the refining master.

When he wanted to make persistent efforts, he suddenly received his first task since he was a guest in the palace, accompanying Dugu Xinyue to the new territory as a supervisor, to put it bluntly, to be a bodyguard.

In his position, he doesn't want people to say that he eats white rice, so he naturally won't shirk.

Speaking of which, this task is actually related to him, because that territory is because of the "Tianping Incident", a territory rewarded by the Zhongzhou Immortal Cultivation Alliance, the lord of the country ordered someone to build a new city, and a member of the royal family is needed to supervise it, and the Crescent Moon Princess, who has always been shrewd and decisive, received this errand.

In addition to him and Dugu Xinyue's four personal female guards, there were also first-class guest secretary Shen Danian, and four second-class guest secretaries of the Jindan period.

Qin Chuan came to the palace for more than half a year, and he behaved very unsocially, so he didn't pay attention to him after getting on the war boat, and he didn't bother to take the initiative to talk, so he took out a newly bought map of Zhongzhou to find out where the new territory was, and found that it was not bordering Montenegro, which puzzled him.

"What, what's wrong with Brother Qin?" I don't know when, Dugu Xinyue came over.

"Why doesn't this new territory border the Empire?"

"Hehe, does Brother Qin know that the Black Mountain Country is surrounded by other territories?"

Qin Chuan nodded.

"That's it, how could the Immortal Cultivation Alliance assign other territories to us? This newly demarcated territory belongs to the Borderland!"

"So that's the case, then these places are far away from the territory, if they are guaranteed not to be invaded?"

"All the territories allocated by the Immortal Cultivation Alliance will not be encroached upon in name, unless the lord's family has completely decayed, and all that to guard against is to be plundered, so such a city must build a teleportation array to ensure timely support in case of attack!"

Qin Chuan completely understood that these territories were equivalent to fiefdoms, and legally belonged to the lord forever, as for whether they could guarantee the actual jurisdiction of the land, it depended on their own ability.

The warship has to pass through two countries, and there is no such thing as "airspace" in this world, as long as you are not intercepted, you can fly as you want.

After five days of flying, they finally reached the territory without any trouble along the way, but when the warship arrived at the site of the fortification, they found that a terrible battle was underway......
