In order to make Huo Ying recover quickly, Yu Bojun had to use some slightly rough methods.

In fact, the best way to restore Huo Ying is to detoxify her, and then slowly recover, as long as there is no continuous yang damage caused by the immortal powder, under the rich yin energy of hell, Huo Ying can quickly recover to her previous state.

However, Yu Bojun was not interested in helping Huo Ying recover from drugs, and he didn't have time to wait for Huo Ying to slowly recover, so he used a spell to raise ghosts and cultivate yin to help Huo Ying recover his vitality.

This kind of ghost cultivation method is a kind of evil art in the world, mainly because the yang energy in the world is sufficient and the yin energy is scarce, and it is necessary to use improper means to collect yin energy, and in most cases, a large number of killing pokes are often the best means to gather yin energy.

But now in hell, there is no need for money when there is enough yin qi, and the method of using this method is simple. It's just that the method of receiving the spell, whether it is an evil ghost or a hell native, is extremely painful in the process of receiving a large amount of abnormal infusion of yin qi.

In just ten minutes, Huo Ying was so painful that she didn't want to live at all, but at this time, even death was an extravagant hope, no matter how she screamed and struggled, the few humans who performed the spell looked at her expressionlessly, as if they were looking at a lamb to the slaughter.

After the spell was over, Huo Ying collapsed on the ground, and he didn't even have the strength to move his fingers, so he could only look at the few humans who had abused him with resentment.

Two women stepped forward and dragged Huo Ying to freshen up and change her clothes.

Huo Ying was tossed by them, only to think that he was dead.

But when the aftertaste of pain wore off, she felt refreshed, full of vitality, and the feeling of comfort was almost like she had been reborn. She looked in the mirror in amazement, and found that not only did the emaciation caused by drug abuse disappear without a trace, but the density of the flame hair had increased a lot, and there was a tendency to quietly spread to the body.

For the flame spirits, the concentration of flames on the surface of the body represents their strength, such as Huo Ying, who only has hair and eyebrows in the shape of flames, is actually a very weak endorsement in the clan, and is far from growing. For example, Huo Ying's father, the former Dead Ghost Emperor of the Fire Tree Dynasty, his entire body was a burning flame, and at a glance, it was a large ball of fire, and he had to distinguish it carefully to vaguely see the human form wrapped inside.

At a normal rate of development, it would take at least ten to twenty years for Huo Ying to reach the current density of flame hair after surgery, but now it only takes ten minutes to achieve it!

It's a miracle!

After carefully observing and confirming that she was not mistaken, she was ecstatic and immediately started her own little calculation.

In her mind, once the human colonists discovered that this method could make her grow and become powerful quickly, she would definitely not use it again, what she needed to do was to experience it as many times as possible before the other party found out, and find out how to use it. Although it is painful, in order to become strong, in order to get revenge, in order to get rid of the control of human colonists, it is worth it.

It is said that the most powerful ancestor in the history of the family can burn the heavens and destroy the earth with a single thought, and if she continues to grow so rapidly, she will be able to reach such a point one day, when any coup tat traitor and human colonist will be wiped out with a simple wave of her hand.

So Huo Ying was extremely uncooperative with Yu Bojun, specifically that she immediately went to the room to suck a large amount of fairy powder.

Yu Bojun didn't notice Huoying's little trick at first, and he was so annoyed that he could only confiscate all the immortal powder around Huoying, and infuse Yin Qi again.

But for the next two days, Huo Ying would look wilted even if she didn't smoke fairy powder, even though various examinations showed that she was too healthy to be healthy anymore.

Yu Bojun was suspicious in his heart, and retrieved the surveillance video from the previous period for observation, and finally noticed the change in Huo Ying. To verify his suspicions, he infused Huo Ying with Yin Qi for a slightly longer period of time.

This real yàn leads to two results, one is that Huo Ying's long flame hair is not only so thick that it turns into a ball of flames, but also grows to the waist. Another consequence was that the prolonged infusion pain almost caused Huo Ying to have a nervous breakdown.

Yu Bojun felt quite amused about Huo Ying's careful thoughts, so after Huo Ying recovered her spirits, he talked to her for a time. Yu Bojun told her straight to the point that the method of infusing her yin qi was originally a kind of ghost cultivation and yin cultivation spell, which could make her grow and become stronger quickly, and he knew in advance, and he didn't plan to hide it from her. As a big customer of the company, it is also the company's pleasure to see that she has become strong, and if she is willing to cooperate with the company's work, then the company will design a training program for her, which is far better than her own secretive exploration. And even if she secretly explored it herself, it was impossible for her to learn this kind of spell secretly, how could a spell in the world be so easy to steal.

Although he said it well, Yu Bojun really didn't expect that the effect of this spell in hell would be so obvious, so after talking to Huo Ying, Yu Bojun turned his head and submitted a plan to the company about using the ghost cultivation technique to experiment with creating powerful yin ghosts and natives.

The technique of cultivating ghosts and cultivating yin is not a profound spell, but when it is in the world, it is in the name of an evil law, but any mage who cares about the identity of face will not use it, and for a place like the world where yin qi is scarce, using this spell to raise ghosts is actually quite worth the loss. This created a blind spot in their thinking, and the mages who entered the Hell did not think of using the Ghost Cultivation Technique here for a while.

After Yu Bojun's plan was submitted, it received considerable attention, and Yong Bowen convened a board of directors to discuss the feasibility of this plan. At this meeting, Xiao Zengxiang unexpectedly became the protagonist. The Changbai faction has cultivated and trained professional spirit animals, and has formed a large-scale industry, which is similar to the difference between raising ghosts and raising beasts, but it can be used for reference. According to the plan provided by Yu Bojun, Xiao Zengxiang initially proposed an intention method, and after obtaining the authorization of the board of directors, the backbone of his own sect and the company formulated a package of training programs. After the board of directors discussed the plan, the site was selected to build a training base, and among the previous Hell natives captives and immigrants, those with strong physiques and simple minds were selected to be sent to the training base for unified training.

At the time of selection, the natives who are at the bottom of the layer and have a family and a business are concerned about the change of dynasty of the Huoshu Dynasty, and the natives who do not care about the change of dynasty are the preferred objects, and before cultivating the real yàn, explain to them the purpose of the real yàn and the inevitable pain, but if they are willing to accept the real yàn, they will become the company's key cultivation objects, not only the real yàn objects themselves do not need to engage in heavy labor, but their families will also be treated preferentially. The preferential treatment plan is listed in the form of a clause, and if you agree to it, you will sign the plan with the company. If you don't agree, it's no problem, you can go back to work and continue to work, and the company won't give you small shoes. And the company also gave a quite preferential experience activity, before signing the contract, you can experience the pain of this kind of trial, if you can accept and endure it, you can sign, if you can endure this pain, then there is no need to sign. Of course, this kind of experience is not free, and in view of the fact that the yin energy infusion of the experience will bring great benefits to the experience, if they cannot sign a contract, then the considerable cost of this experience will be credited to their account, and they will be repaid by the electronic share of their labor income in the future.

In this way, the first batch of more than 3,000 Hell natives were selected to participate in the unified cultivation of Shiyàn. The first phase of the real yàn lasted for thirty days, and about a thousand natives collapsed and died because they couldn't bear the pain, in fact, more than two thousand successfully survived, and all of them got different Cheng dù to become stronger, and about 300 of them strengthened Cheng dù the highest, and actually turned into a demon king!
