The method of blood refining can be said to be an advanced method for refining the undead. Using the essence and blood as a guide and the catalysis of secret methods, it can completely refine any unconscious undead in an extremely fast time, making it

Being connected to the master's mind makes it easier to control.

This blood refining method is extremely simple, but there are hundreds of changes in the evolution of the method. As the method is played, Meng Fei's expression gradually becomes serious. The king-level bone pill he just refined, but

Only used it for half an hour.

But in order to completely refine this skeleton, Meng Fei has been using it for more than an hour, but there is still no reaction from this skeleton. If this continues, it won't be long before all the energy and consciousness in his body will be exhausted.

"Continue with the blood refining. Since I asked you to refine it, I'm sure of it. Just don't worry." Perhaps feeling the emotion in Meng Fei's heart, the little dragon mouse said lightly.

When Meng Fei heard this, he became determined and his hand speed became a little faster. Although the blood refining technique was extremely complex, he never made any mistakes.

Sure enough, two hours later, the calm skeleton suddenly underwent an astonishing change. Under the rich spiritual energy, traces of dark and sinister aura were faintly derived. The entire skeleton was made of warm soft jade.

, instantly turned into pitch black.

The spiritual energy dissipated, and what came out was actually billowing bad energy, and it was extremely shocking.

Three hours later, Meng Fei's eyes suddenly turned black. The energy in his Ming Mansion had been exhausted. Only a small amount of energy was still flowing slowly in his meridians.

Then, at this moment, the evil aura was even stronger on the skeleton. As it rolled, there was a faint roar, as if it was unwilling to be refined, and there were faint signs of devouring its master.

Just when the skeleton was about to devour its master, the energy in Meng Fei's body had been exhausted, and his face instantly became bloodless, losing its energy supply. The skeleton's shape also changed drastically.

All the bones were gradually stretched, slowly becoming longer and thinner. At the same time, an extremely violent evil erupted from it crazily, threatening to rush towards Meng Fei.

Meng Fei's vision turned black, and he felt weak in his body. However, the refining of this skeleton was not completed yet.

"There is only one last step left to complete the blood refining." Meng Fei's eyes were full of madness, and his fist was like a drum, hitting his chest hard, and a stream of blood essence was forced out of his body.

"The last step, melt the soul, refine it for me!" Meng Fei breathed heavily, his face full of pain, but his hands still kept on finishing the last spell, and the blood he spurted out was in the spell.

Under the pull of the figure, it finally landed on the Google and was absorbed instantly.

Buzz!

When the last magic formula fell, the skeleton suddenly trembled, and the evil rolling on it dissipated instantly, and was finally completely purified. The entire skeleton glowed faintly, like a piece of ink jade with restrained brilliance.

"Little Dragon Rat, this skeleton has been blood-refined. The next thing is left to you. You can fuse the bone elixir with it." Meng Fei's breath was confused, and his face was a bit gray, but he still managed to do it.

Open your mouth.

As soon as these words came out, the excited voice of the little dragon mouse sounded: "You can rest in peace and cultivate yourself. You don't have to worry about the next thing."

Hearing this, Meng Fei's pale face showed a slight smile, and he said weakly: "That's good. I've exhausted myself quite thoroughly this time and need to recuperate for a while. During this period, don't wake me up unless necessary."

After saying this, Meng Fei took out a few pills for strengthening the body and swallowed them all.

After the elixir entered the entrance, it turned into pure spiritual power and entered the meridians. Meng Fei's aura became much more stable, but his face was still extremely ugly. After all, a large amount of blood and essence was lost in the body, which could not be replenished in a moment.

The slightly illusory figure of the little dragon mouse appeared next to Meng Fei, and put the dark skeleton into the iron sky. Looking at the young man sitting cross-legged, his eyes showed a bit of relief. After a long time, he said to himself

Yu chuckled and said: "It's a good decision to choose him as my master... Maybe, I can really borrow his power..."
