In the exchange of the main god space, the exchange of any bloodline and secret method, if you want to strengthen a level, you must have a low-level exchange as a foreshadowing to upgrade layer by layer, that is to say, if you want to strengthen the D-level ability, you must first strengthen a corresponding E-level ability.

Although Ma Gaoyi said that he had to think carefully before decomposing the advanced side plots, in fact, if Xi Cheng wanted to strengthen any bloodline or ability, he had to split the D-level side plot and start strengthening it with the ability of the E-level side plot.

Xi Cheng is not a pure vampire, his vampire physique is the product of genetic fusion of scientific and technological power, not through the existence of another vampire after the first embrace, so his vampire physique is imperfect and cannot be evolved! In this main god space, Xi Cheng may be able to find a way to make up for his own shortcomings and evolve himself into a real vampire, but Xi Cheng doesn't want to do this.

It's good now, immortal and immortal, but you don't have to be afraid of sunlight and divine energy, this can be said to be the dream physique of all vampires in the whole world, even if it is worth paying some price, not to mention that there are too many bloodlines and abilities in this main god space that can be strengthened, and it is a bit narrow to limit your vision to one vampire bloodline. The most important thing is that this vampire constitution brings Xi Cheng a kind of memory that he doesn't want to recall, even if Xi Cheng is strong by relying on it, but he instinctively rejects it in his heart, just like the attitude of human beings towards nuclear weapons.

Xi Cheng's eyes hurriedly swept from the exchange list at the main god, all kinds of magical and powerful bloodlines and abilities deeply attracted Xi Cheng, but they could not be strengthened because of the lack of side plots and reward points, and some bloodlines and abilities that could be gradually strengthened from the E-level side plots did not necessarily echo Xi Cheng's thoughts and habits, or simply conflict with his current vampire physique, such as the light bloodline and the Saint Seiya bloodline, If this kind of righteous bloodline is exchanged for Xi Cheng, it will instantly have an incompatible conflict with his own vampire bloodline, and maybe Xi Cheng will explode directly.

After casting the net over and over again, Xi Cheng's eyes were finally attracted by a bloodline ability—the Corpse Bone Vein!

Bone Vein - The owner can freely change the number and shape of his bones by controlling the number of bone cells and bone composition!

The corpse bone vein is divided into three levels of strengthening, starting from the E-level side plot, it can be strengthened all the way to the level of the C-level side plot, in terms of sustainable development, the corpse bone vein can only be regarded as a medium good choice, far from being the best, but Xi Cheng is very fond of the ability and characteristics of the bones in the corpse bone vein, he was originally a vampire physique suitable for hand-to-hand combat, and this research topic was also studied in order to create the most powerful soldiers in the world.

Now, if it can be combined with the characteristics of strengthening and controlling the bones of the corpse bone vein, whether it is defense or combat, a lot of variability has been added, although it is only a brief introduction, but Xi Cheng sees an opportunity to greatly improve his strength.

Xi Cheng thought secretly in his heart: "My strength is not necessarily weaker than Ma Gaoyi and Li Manyun now, it is my vampire physique that depends on it, instead of pushing my strength all over again, it is better to treat the vampire physique as a tree trunk, and then use its ability as a branch and leaf to cooperate, maybe I can enhance my strength more quickly!" ”

One thought is certain, the corpse bone vein has become one of Xi Cheng's inevitable choices, and to strengthen the corpse bone vein, you need to use an E-level side plot and 1000 reward points, after deducting these, Xi Cheng still has 2 E-level side plots and 9000 reward points left!

Xi Cheng's brows furrowed slightly, he didn't understand the importance of reward points before, and he was excited to kill Ji Chang with his own hands, knowing that he should use other methods to bypass the restrictions of the main god space and kill him, so that it would not be wasted, at this time, although Xi Cheng didn't regret it, but he also had some regrets.

After browsing again, Xi Cheng's gaze was once again locked on the strengthening ability in a "secret method" item, which was a technique used for cultivation.

"Three Yin Demon Scroll" - to absorb the qi of the three yin, practice the demon element in the body, achieve the three yin demon gods, immortal and indestructible, life and life are cut off from the three realms, do not enter the reincarnation, is the supreme secret method of cultivating demon skills!

Xi Cheng was just a little curious and surprised when he first saw this introduction as an exercise that could be strengthened from the E rank to the S rank, and wanted to see how perverted this exercise that could be strengthened all the way to the S rank strength, although he was also shocked by this introduction when he first checked it, but he was a little unclear, until he checked it in detail from the main god, and suddenly gasped.

The so-called three yin qi is the corpse qi of a person after death, the power of the stars of the Taiyin star, and the evil qi of the earth's center!

Absorbing these three kinds of yin and evil qi into the body, and then cultivating them with secret methods, you can cultivate an extremely strong demonic qi, and this extremely pure demonic qi is also called the demon yuan!

And the Three Yin Demon God, the main god space did not make a detailed explanation, but only explained that it is a terrifying realm that can only be achieved by strengthening the "Three Yin Demon Scroll" to the level of A-level, once the Three Yin Demon God is practiced, you can temper the immortal and immortal supreme demon body!

The so-called three paths are humanity, Shinto, and immortal...... It means that once anyone cultivates the "Three Yin Imperial Demon Scroll", it doesn't matter when the realm is low, but once the realm is high, it is equivalent to being cut off from these three realms, falling into the demon path for eternity and eternity, not entering reincarnation, and being willing to be abandoned by the heavenly way!

Although Xi Cheng was a vampire, when he learned about the horror and perversion of the so-called "Three Yin Imperial Demon Scroll", he couldn't help but grin secretly, such a technique...... Such a pervert...... It's so cute!

The exercises are different from the bloodline, once the bloodline is strengthened, it is yours, but the exercises need to be cultivated step by step, so at the beginning, even if the E-level enhancement is exchanged, the power may not be able to be revealed.

However, Xi Cheng didn't take the warning of the main god space to heart at all, what is self-isolating from the three realms and not entering reincarnation...... Is there any difference between the current Xicheng?

In the past century of becoming a vampire, Xi Cheng has indeed been a little lonely and lonely, but all this has changed with the entry into the main god space, in this magical place, there are dangers everywhere, and danger can rejuvenate Xi Cheng's inner passion!

However, in order to ensure that this passion continues, Xi Cheng must first make himself stronger, and only by becoming stronger can he survive in a more dangerous environment, and then wait for the next passion to come, so in Xi Cheng's heart, a hundred words of warning are not as important as a passionate experience.

"The greater the danger, the more perverted the power of this exercise...... I love this exercise! At this time, Xi Cheng had a somewhat nervous smile on his face, as if he had found a toy that he was extremely interested in, and he had a feeling that he couldn't wait to try it.

"Lord God, disassemble the D-rank side plot into three E-rank side plots!" Xi Cheng felt that he couldn't wait, so he no longer suppressed himself, and started to act directly in the main god space.

The first thing to exchange is the corpse bone vein, pay for an E-level side plot, after 1000 bonus points, a pillar of light shrouds Xi Cheng and holds it up, and the slightest point of light enters Xi Cheng's body from the surrounding void, and a tingling and itchy feeling comes from every bone crack and every cell in Xi Cheng's body.

Under Ma Gaoyi's gaze, Xi Cheng slowly fell from mid-air, and the whole person did not look the slightest change from the outside, whether it was body shape, appearance or temperament, all of them were the same as before, but everyone knew very well that Xi Cheng must have exchanged for a certain ability, a certain ability that could not be seen from the outside!

"How? What level has your vampire bloodline been strengthened, viscount or baron? Ma Gaoyi came over and asked with an extremely interested expression on his face, Li Manyun and the two newcomers on the side were also curious, but they just stood in the distance and did not approach.

Xi Cheng squinted and glanced at Ma Gaoyi coldly, his right hand was raised instantly, his palm was aimed at Ma Gaoyi, and a white bone spur suddenly broke out of the palm of his hand, stabbing Ma Gaoyi's right eyeball!

The feeling of danger enveloped Ma Gaoyi, and at the moment when he was stabbed and became a one-eyed wolf, Ma Gaoyi jumped backwards 2 meters away from his feet, and glared at Xi Cheng with a hideous expression on his face, his mouth cracked, and the two rows of teeth had begun to mutate, becoming sharp wolf teeth, and the ten fingers of his bluff hands began to thin and lengthen, and his nails quickly jumped out, becoming as sharp as daggers.

Li Manyun and the three of them on the side were slightly surprised by the changes in front of them at this time, but when they saw that Xi Cheng and Ma Gaoyi did not continue to move, they were relieved.

Xi Cheng's face still had an evil smile, and the bone spurs that jumped out of the palm of his right hand slowly began to slowly retract into the palm in front of everyone, the bone spurs were smooth and firm, and after retracting the palm, the original round wound began to quickly close and heal, and in the blink of an eye, it became a small wound that was not visible to the naked eye, and this wound quickly disappeared completely with the help of Xi Cheng's vampire physique.

"Good ability, very sneak attack, people who are not careful can easily be hit hard by your move!" Ma Gaoyi's vision of his whole body had all disappeared at this time, and he looked at Xi Cheng with a thoughtful expression on his face and said.

Xi Cheng raised his right index finger and shook his index finger slightly when he heard Ma Gaoyi's evaluation, and retorted: "Sneak attack is indeed very strong, but this doesn't mean that you can only sneak attack!" As soon as the words fell, Xi Cheng's shoulders, under his ribs, on his back, and on his shoulders, at the same time, several slender bones pierced the flesh and blood, Bai Sensen's bones were not stained with flesh and blood at all, and the front section of the fracture was extremely sharp, and from Xi Cheng's upper body, these dozen feet long bone spurs suddenly pierced out, which looked extremely hideous at a glance, like a mutated biochemical monster as terrifying!

"This ability I redeemed is called the Corpse Bone Vein, which is a kind of ability that can control its own bone bud cells to control the number and shape of bones throughout the body!" Xi Chengyou withdrew all the dozen or so hideous bone spurs that emerged from his body, and the punctured wounds on his skin quickly closed and healed at a speed visible to the naked eye.

"Bone veins? I recognize this, it's the Blood Inheritance Limit in Naruto, my boyfriend likes to watch this, I said it looks so familiar just now! Yang Liu, who was on the side, heard Xi Cheng's words, and suddenly said in surprise.

This enhancement skill can only be used by a person with a vampire physique like Xi Cheng to exert its power perfectly, and even if other reincarnators exchange it, it is difficult to restore the broken muscles and skin after growing bones out of the body, but it is not a problem for Xi Cheng at all.
