The zombies made by the above three methods are extremely powerful in themselves, and most importantly, they are all autonomous, and some of them can even blend into the crowd without being detected after years of sacrifice.

And from the black book, Fang Jin also learned about the hierarchy between zombies.

The first is a kind of zombie that can only jump around in the movie or in the novel, and the body is very hard, but there is no autonomous consciousness, and it can only be sucked up blood by the instinctive tendency, which generally cannot be called stiff, because the transformation of the body is not completed, so it can only be a corpse, but it can move, so it is called a walking corpse.

The second type, the body is extremely hard, the strength is infinite, has been basically transformed, and grows heavy long hair on the surface, this kind of zombie is called hair stiff, and due to different characteristics and the color of the long hair, it is divided into white stiff, black stiff, red stiff and so on.

The third type, the body has lost its long hair, and its actions are no different from those of a living person, and it has an autonomous consciousness, and because of the combination of its own evil qi and resentment, it has given birth to some strange abilities, and the most important thing is that this zombie will become a human during the day, but at night it will revert to a thin man-eating demon.

This kind of zombie was generally called the god of the underworld in ancient times, and even many ordinary people who were fooled would worship it, but in fact, those Taoist priests or mages prefer to call them the underworld, if they see it, they will kill one when they see one, so that in modern times, this kind of zombie has long been extinct.

The method of refining the corpse recorded in the black book, after the refining is successful, what is refined is this kind of demon that is like a living person.

As for the zombie level further up, there is no record in the second page of the black book, and Fang Jin can't turn the third page for the time being, so he only knows this.

The rest is to use zombies to continue life, but this method had to be abandoned after Fang Jin's careful study and comparison, because although this method can link his life with zombies, he also has to bear the price of becoming a monster that is not a human or a ghost, and at the same time, he must be careful of the punishment from the Heavenly Dao.

It can be said that once you succeed, then you may have to hide in the shadows for the rest of your life.

Fang Jin is still very young for the time being, and he may not be able to find a way to extend his life in the future, so this method of using zombies to prolong his life will not be used when he is not in a desperate situation.

However, he will not use the method of continuing his life, but it does not mean that Fang Jin does not want to refine his own zombie, but the methods mentioned in the black book are too difficult in his opinion, and the three methods, with his current net worth and realm, it can be said that there is really little hope.

Frowning, Fang Jin's face was a little gloomy, so that the little ghost Xiaojia only dared to squat in the corner near the bathroom, for fear that Fang Jin would find an opportunity to punish him.

After thinking for about five minutes, Fang Jin seemed to have made up his mind, took out a purse-like thing from his arms, opened the purse, and saw that it contained a blood-red bead.

Taking the bead out of his purse, Fang Jin took a closer look, he didn't know what this thing was at first, and Wu Jiu didn't mention it in his memory, but he knew that it was originally put together with the black book.

However, just now when he received the information of the Black Book Inheritance, one of them introduced the specific use of this bead, this bead is called the essence of the blood, and there is only one use, that is, it can infinitely produce the yin blood used to refine zombies.

At first, after learning about the use of beads, Fang Jin was still extremely excited, because once he had infinite yin blood, then he could continuously refine zombies, and as long as there was an army of these zombies and nuclear weapons were abolished, then it could be said that there was nothing in this world that could threaten him.

However, when he saw the methods and side effects of producing yin blood in the back, he felt as if he had been drenched in cold water in winter, and he completely wilted.

If the spirit of the dark blood wants to transform into yin blood, it first needs to be integrated into Fang Jin's body, and it is not just stored in the body like a magic weapon, but it must be completely fused.

After the final complete fusion is successful, then Fang Jin's blood will become the so-called yin blood, so theoretically there will indeed be infinite yin blood.

If this were the case, Fang Jin would not be anything, at most it could be regarded as a use of increasing his own blood.

But it's not that simple, first of all, once the blood essence is fused, Fang Jin will gradually begin to transform into a nether creature in the future, this transformation is theoretically irreversible, and in the process of transformation, Fang Jin will gradually lose some abilities including body temperature, pain, taste, and visual color.

This transformation would continue until Fang Jin succeeded in turning into a nether creature, and if he lost anything in the transformation process, he would never be able to get it back.

On the other side, the little ghost Xiao Jia who was squatting on the ground stretched his neck, and looked at the bead in Fang Jin's hand with some greed, it didn't know what it was, but the instinct of the body was driving it to swallow the bead in one gulp, and the black liquid slowly dripped from its mouth, and disappeared when it touched the ground.

Xiao Jia felt that she couldn't help it anymore, but the next moment, it seemed to remember something, her blue purple body shivered fiercely, whined a few times, and then turned her head as quickly as before and pretended to turn a blind eye.

"Whew!"

With a sigh of relief, Fang Jin stuffed the beads into his purse again, and then hid them close to his body, he was not ready or determined to turn into a nether creature.

"There's still time!"

Fang Jin pretended to tell himself, as if he was adding weight to his decision.

Indeed, he still had time, at least nearly eighty years left for the monk's age, and if he was able to break through to the foundation building period during this period, then it would be even longer.

After sorting out all the things, and then carefully hiding the black book, Fang Jin was ready to cultivate, only when his own strength improved, he could go more smoothly in the future road, and naturally he would get more.

"Watch the door, don't allow anyone to disturb me while I'm cultivating!"

He gave an order to the little ghost Xiao Jia, and then Fang Jin entered the state of cultivation.

Xiao Jia tilted her head and looked at Fang Jin for a while, then her body turned into a black gas and floated to the door of the room and squatted down again, reaching out and digging it in her arms, only to see a piece of white toffee appear in the blue and purple palm, which it stole from Fang Jin.

Cautiously glanced back at Fang Jin, Xiao Jia's dark eyes flashed with a little red light.
