Click, Hong Yu inserted the sword back again, and was very satisfied.

As for the treasure knife, it must not be bad, Hong Yu put away the two Xuanbing again, and there was nothing else in the cabinet.

He opened the drawer in the center of the stone room, which should have been filled with some account books, but the moment the drawer was opened, all of them turned into ashes. Waiting for the dust to clear, there was an emerald ring in the drawer, emitting faint spatial fluctuations, which felt very similar to Hong Yu's spatial Tiejue.

He took it out and put it on his hand.

"Alright, let's go. ”

Hong Yu took the two elders back to the passage, and with a flick of the jade ring in his hand, the nine assembly lines in the cave turned into a piece of light sand, and slowly collected it.

Hong Shen and Hong Yin followed the young master, and now they are no longer surprised by this strange thing.

After taking away the nine assembly lines, he and the two elders thoroughly checked the place again, and there was indeed nothing left, and then returned from the cliff.

Hong Yu originally hoped to get Feng Jiuxiao's inheritance, and go back and hand it over to Sun Banshan, but if he didn't find it, forget it.

The three of them entered Feng Jiuxiao's treasure house, and it took two hours, and when they came out, it was already late, and everyone camped in the valley to prepare to leave tomorrow.

As for what the young master got, no one would be stupid enough to ask.

After finishing the cultivation in the evening, the voice of the Qixi Sword Spirit sounded: "I roughly estimated, these nine assembly lines, can barely put together one." ”

Hong Yu was overjoyed: "Which one is it?

"The lowest-level one, but it's a bit inaccurate to say that, it's mainly the lowest-level one, but it can also produce seventh-grade and eighth-grade Xuanbing. In that case, the production capacity will be greatly reduced. ”

Hong Yu asked again: "What is the production capacity?"

"If you produce the Nine Rank Xuanbing, if the materials are sufficient, you can produce thirty pieces per month. There are only ten pieces for the eighth grade, and only three pieces for the seventh grade. If you want to play with the high level, you need to find some precious materials, and then transform this assembly line. ”

Hong Yu said: "What materials do you need? Give me a list." ”

"You first find the brain crystal of a super first-grade desolate beast. ”

He didn't know where to find the super first-grade desolate beast, and even if he found it, he probably wouldn't be able to hunt it.

The deterrent power of the primeval demon totem no longer seems to have an absolute advantage in the face of a first-grade desolate beast, and in the face of a super-first-grade desolate beast, Hong Yu has no confidence.

Let's put aside this matter first, Hong Yu with the help of the Qixi Sword Spirit, can be regarded as having completely figured out this Xuanbing workshop.

At that time of Feng Jiuxiao, the development of Xuanbing Jishu far exceeded that of now. And Feng Jiuxiao is the culmination of a certain stage in this great era. His greatest contribution to Xuanbing Jishu is "quantification".

This philosophy is vividly reflected in his workshop.

The reason why Xuan Bing is precious and cannot be copied is because most of the Xuan Bing are made with high-grade Desolate Beast Brain Crystals as the core material. Even if it is a wild beast of the same race, there can be no two identical ones, just like the truth that there are no two identical leaves on Shijie.

Different wild beasts naturally have different brain crystals. Brain Crystal can bring special skills to Xuan Bing, and the Brain Crystal of the Desolate Beast is different, and of course the Xuan Bing is also different.

However, in the first half of Feng Jiuxiao's life, after independently producing countless Xuan soldiers, he began to devote himself to "measuring" the impact of various raw materials in these Xuan soldiers on the power of Xuan Bing.

And on the basis of a large amount of production experience in the first half of his life, he found out some types of Xuanbing and the optimal power scheme.

For example, he found the most powerful of the same kind of desolate beast's brain crystal as the core, analyzed the various components in that brain crystal, and then recorded this data.

His workshop tries to imitate this composition as much as possible.

Hong Yu wondered before, how could different wild beast brain crystals be mass-produced?

Feng Jiuxiao's solution was to hunt all kinds of beast souls, extract different kinds of souls from them, deploy a stable artificial "beast soul", and then inject them into the mineral crystals that also stored energy, creating a very stable and uniform "brain crystal".

When the "composition" of the brain crystal is stable, it can be supplied as a fixed raw material, and other raw materials can be set in stone, so the biggest problem of mass production will be solved.

As for the skills of refining Xuan Bing, Feng Jiuxiao solved it all through that assembly line.

After understanding all this, Hong Yu still sighed: That era was too great

After figuring out the basic principle, it is still far from the actual implementation, and it is impossible for Hong Yu to copy an assembly line now. This was not only because he could not find the various precious materials for the assembly line, but also because he was not an appraiser himself and could not complete this kind of fabrication.

After explaining these things to Hong Yu, the Qixi Sword Spirit sent out an invitation very enthusiastically: "There is still a little time tonight, how about going to fight in the Ancient Realm of Annihilation?"

Hong Yu did not doubt that he went in, and he didn't come out until dawn, the pain was unbearable, but it was worth the money. Every time he enters and exits the Ancient Realm of Annihilation, Hong Yu's comprehension of battle and tempering of will have made significant progress

On this day, the Desolate Beast Cavalry Regiment returned to Chijinchuan, but Hong Yu disappeared with Hong Yin and Hong Shen.

Huang Qianxiu, who had just joined the team, was a little strange and asked Su San: "Where did the young master go?"

Su San smiled and said nothing, the newcomer still didn't understand the rules.

The Desolate Beast Cavalry Regiment returned to Chijinchuan, and still stayed in that inn, and after waiting for three days, Hong Yu and the three of them would also come, and it didn't seem to be any different. But Hong Shen and Hong Yin's eyes would flash with a trace of irrepressible excitement from time to time, and it was obvious that this trip was quite fruitful.

After Hong Yu came back, he called Zhao Yue over: "I came to Guangyang County this time, mainly to choose my own territory. The territory of a township is not small, and Chijinchuan has changed enough. But I'd like to fight for it, and the nearby mountains and forests should be included in my territory. How about you stay and guard this territory for me?"

Zhao Yue was overjoyed, and bowed down: "Thank you, young master, don't worry, I will not let you down." ”

Hong Yu smiled and glanced at him meaningfully. Zhao Yue seemed to be conscious.

Subsequently, Hong Yu left Chijinchuan with the Desolate Beast Cavalry Regiment, and after they left, the heads of the Huang brothers were all hung at the entrance of Chijinchuan Town.

When the news of Chijinchuan came back to Guangyang City, Fan Wencheng suddenly became anxious and had a toothache. An Yiren didn't expect that not only did his Jihua not be realized, but let Hong Yu choose the territory in Chijinchuan.

Although that place is a poor and remote place, it is rich in elixir, and there is a lot of oil and water every year. Huang Tianke controls Chijinchuan, but during the New Year's holidays, there is a lot of filial piety for the heroes and strongmen in Guangyang County, and after a year, just the An family can harvest 100,000 taels of silver from Huang Tianke, but now this fixed income is gone

The two sat together, and An Yiren sighed: "That's it, since you can't leave, let's treat him well, and when he comes back, I will gather all the local heroes and hold a banquet for him......"

When Hong Yu came, no one from the local Haoqiang came forward - Lan Renlong, who "came forward", was destroyed by Young Master Yu - and now, An Yiren wants to convene everyone to feast Hong Yu, which is obviously a gesture of submission.

Although An Yiren was very unwilling, he could only accept the fact that Guangyang County's practice of "the dragon does not cross the river" was terminated in front of Young Master Hong Yu.

But before he finished speaking, a subordinate hurriedly ran in: "Master, Hong Yu didn't come to Guangyang City, and left directly." ”

"What"

The two of them were taken aback and felt that something was wrong.

Hong Yu always felt that Fan Wencheng was uneasy and kind to recommend Huang Qianlan to himself, but he never understood what Fan Wencheng's intentions were.

In the past few days, I have sometimes chatted with Huang Qianxiu on the road, and after listening to her talk about her previous experience, Hong Yu suddenly understood: Fan Wencheng wanted to use Huang Qianxiu's hand to force him away.

Huang Qianxiu is spicy, in order to protect her sister, she will do everything, if she also gives herself a drama of "being raped and asking for responsibility", she can really only leave Guangyang County in shame.

Thinking of this, Hong Yu was even more annoyed with Fan Wencheng, and no longer returned to Guangyang City and left directly.

Fan Wencheng and An Yiren hurriedly rode horses to catch up, but Hong Yu calculated this and led the Desolate Beast Cavalry Regiment over the mountains and mountains. Anyway, they had beast mounts, which were faster than riding horses on pipes. Fan Wencheng and An Yiren couldn't go any longer when they chased them to the border of Guangyang County, so they had to go back nervously.

After leaving Guangyang County, Hong Yu was not in a hurry, and advanced at a normal speed, and the team also returned to the official road. Hong Yu sat in the carriage during the day, and entered the Ancient Realm of Silence every day to fight and train, and made rapid progress, and when he arrived in Wudu, Hong Yu already felt that he was about to break through

He is already in the late stage of the five-grade Yuanding, and his hard work along the way will eventually pay off, and Hong Yu feels that he is a layer of window paper from the four-grade general method. It is very likely that the next time you cultivate, or the next time you enter the Ancient Realm of Silence and come out, you will break through.

So today, he entered the Ancient Realm of Silence with great interest and was abused, but after a fight, he only killed more than 500 puppet warriors, and there was no movement in that barren city.

Hong Yu wondered: "What's going on?"

Before he could finish speaking, he was ostracized from the Silent Ancient Realm by a force of liliang.

Qixi Sword Spirit said helplessly: "Young man, the Silent Ancient Realm needs energy to open, and now its energy is about to run out, and there is no way to support you to continue cultivating......"

Hong Yu was furious: "I knew that you didn't have a good heart when you introduced me to the Ancient Realm of Silence, so you were waiting for me here."
