In many legends of the human world, the blood of demons is the most filthy blood in the world!

Perhaps it's because the demon's blood contains powerful dark power and magic, and because of the strong aggressive nature of the demon's genes, it often causes unknown mutations to the creatures that come into contact with the demon's blood.

As far as Roy knows so far, there are people like him, blood can transform into lichs, and there are also people like Dracula who can transform into vampires, and similarly, there are creatures that can transform into monsters, and even like the world of Yashan, by combining humans and demon blood, they gradually become muscular and ugly, and because of the influence of demon blood in their bodies, these mutant races tend to be irritable and bloodthirsty. Then he became what people call 'orcs'......

And in either case, it shows the terrible ...... of demonic blood

In fact, since discovering that his demonic blood had turned Kassandra into a lich, Roy has not stopped researching his own blood.

While Roy hadn't encountered any of his Frost Demon species to date, he didn't know if their blood would be able to turn a creature into an undead creature like a lich like his own, but at least Roy himself was.

Cassandra is an example, her soul was first taken by Roy after she fell into the abyssal world out of a strong hatred, and then Roy fed Kassandra's corpse with demonic blood to transform her into a lich.

But then, judging from Roy's experiments during the three years he spent in the Darkblood World, the transformation of his demonic blood into the Lich was not 100%!

He discovered that if he wanted to directly transform the corpse into a lich through his demonic blood, he must first meet a condition, that is, the corpse originally had magical power during its lifetime, or at least had the potential for magical power, that is, the transformed person must at least have the potential to become a mage, so that Roy's demonic blood can transform it into a lich.

In addition, the body with no potential will be corrupted by the dark power contained in the blood after coming into contact with Roy's demonic blood, and eventually turn into a pile of bones.

Why this is so, Roy guesses that this may be due to his demonic blood choosing his physique, because lichs are born with some knowledge of driving away other low-level undead, which requires them to have some magic in their bodies.

Moreover, the second condition for this transformation of a lich through demonic blood is that the object must be a corpse, not a living person! Because death is the first step to becoming an undead creature......

So, this has led to a phenomenon, that is, if Roy uses those corpses whose souls have dissipated and transforms them into lichs, then this lich has no life box, not only is it not conscious, but once it is defeated and destroyed, it can no longer stand up again, and it will become a one-time consumable.

Like the corpses in Arantir's troops......

However, when Roy tried to use magic to simulate the power of death, he found that it was not so easy to do, because the power of death required by necromancy was very difficult to simulate......

And if you kill a person directly, get their soul in their hands first, and then transform it into a lich, maybe because the soul has not completely dissipated, so that the resurrected lich will retain a considerable degree of consciousness, they will be like Kassandra, and they can even remember the events of their life, but for Roy, who holds their soul, they will not obey, but choose to resist!

Why is this happening, Roy tried it a few times, and found that it was due to the uneasiness in the lich's bones, because the soul was in the hands of others, and they would subconsciously want to take the soul back and save it for themselves.

Obviously, Roy was a demon, not a necromancer, and he couldn't mark these sane lichs as necromancers, so he couldn't control them.

But Kassandra, her soul was voluntarily sacrificed to Roy, which is equivalent to a contract mark, so for Roy, she is obedient.

Lichs without intelligence are easy to control, but they are weak and unable to grow; And the intelligent lich has room to grow, but it doesn't listen to Roy's control, which makes Roy a little annoyed all the time.

He also found some records of the mages of the Yashan world in history, who voluntarily transformed into lichs through rituals through rituals through the books he took from the city of Ulan Bryth, and in these records, Roy found that all the lich transformation rituals actually mentioned a secret potion, the composition of which is unknown, but it is said to be highly poisonous, and they were able to transform themselves into lichs by taking this secret potion, and then through specific rituals, they were able to transform themselves into lichs.

Therefore, Roy guessed that this so-called secret medicine probably contained the blood components of the frost demon in it, and through this secret medicine and ritual, the mages were able to control their own souls, so naturally they would not rebel against themselves......

Roy's demon's blood has such drawbacks, which means that he really can't pull out a large army of undead by relying on his own demons, those low-level lichs who don't have intelligence can't control too many undead creatures, only Kassandra, she can improve her strength by sucking the life force of living creatures, and Roy If he wants a large undead army, he must rely on Kassandra.

The strength of Fortress Dendra is beyond Roy's imagination, but Kassandra's strength improvement is not something that can be achieved overnight, and Roy must find another way.

The previous dark snow disaster that covered the entire forest gave Roy inspiration.

In that dark and snowy disaster, none of the fallen creatures became undead, because the cause of their death was the desolation virus and magic virus contained in Roy's magic.

So where did these two viruses come from? The perfect T-virus in Roy's body, of course! The principle is that the magic used by Roy is a mutation that is reproduced after combining with the perfect T virus in his body and activating it, that is to say, the desolation virus and the magic virus will only appear with magic when Roy uses magic power, and when magic power is not used, this virus only exists in Roy's body in the form of a perfect T virus.

Inspired by the Desolation Virus and the Magic Virus, Roy suddenly discovered that he never let a living creature drink his demonic blood!

It stands to reason that his demonic blood not only contains the special dark power of the Frost Demon, but also the pathogen of the Perfect T-virus.

But Roy then realizes that the Perfect T virus doesn't seem to be effective against dead bodies, and it doesn't seem to be contagious, which he set up so that he would use it to strengthen his body without side effects......

So Roy thought about what it would be like if he slightly modified the attributes of the perfect T-virus in his demon's blood, so that it could regain that powerful contagious effect, and then put it into the water source of Dandra Fortress?

Don't say anything cruel or anything like that, in fact, Roy's identity as a demon has long been destined for him to be an enemy everywhere in any world, and everyone who sees him can't wait to chop him into meat sauce, in this case, if Roy still has any human thoughts about the Virgin, then he would have been finished I don't know how many times.

Since they are enemies, it is natural to kill them by any means......

Roy's current body has a super recovery ability, and the wound cut by Frost Sorrow healed in just a few seconds, which made Roy want to fill a bottle with his demonic blood, and he had to reopen the wound repeatedly, which was very delayed for a while.

The fluorescence of purple and light green, in the transparent glass bottle, presents a strange beauty, after collecting such a bottle of blood, Roy first put it into the system space once, and then took it out again.

In this way, this vial of demonic blood becomes an ingredient in the system.

Only then did Roy start redefining the properties for it......

Blood of Osiris:

Escaped from the demonic blood of the demon Osiris itself

It never solidifies and can be diluted with any liquid

Once the dilution effect is generated, the Perfect T virus in the blood will redegenerate and revert, restoring its strong infectivity and mutation

This is Roy's new definition of this vial of demonic blood, as for what kind of effect will be produced after the degradation and inversion, it is not something that Roy can control......

After paying a very low price of about two souls and redefining it, Roy clearly saw that the demonic blood in the bottle had gradually changed from the original color of purple and pale green to a faint blue color!

Sure enough, the system dad is as powerful as ever......

Roy summoned a demonic eye again, tied the vial of demonic blood to the winged demon's eye, and then manipulated it to become invisible.

Then I saw the bottle of demonic blood, which gradually disappeared along with the demon's eye.

Seeing this, Roy nodded in satisfaction, and as soon as he put his hand down, the Demon Eye flew into the air and flew towards the Dandra Fortress again.

Juliel watched in confusion as Roy had done all this, and asked him curiously, "What the hell are you going to do, dear?" ”

Roy laughed, stood up and wrapped his arms around Juliel's flexible waist, stretched out his fingers to pinch her chin, and said mysteriously, "Remember the human nuclear weapons we used in the previous world?" ”

"Remember, what's wrong?" Juliel looked at Roy with watery eyes.

"This time, I'm going to show you what a biological weapon ...... is"
