Yes, Cook found that something was wrong, and countless records were checked by Cook one by one, and while Cook was checking, he pondered in his heart, the highly toxic species that died by injecting the blood of the demon for the first time, the species that survived. Second. The third time, the fourth time.

"Damn, it's screwed, it shouldn't have been added to the eaux-de-vie. After Cook studied it, he suddenly discovered that the blood of this demon race is actually indirectly absorbing life force to strengthen himself, and what is the power contained in the blood, that is, the power of life is not.

The demon blood itself has assimilation, and these highly poisonous creatures absorb life force, so the speed of the two is completely different, after all, the water of life has not been converted into the vitality of these test products, and then most of them are assimilated by the demon blood, and once the demon blood is assimilated and swallows up a large amount of life force, then the assimilation power of the demon blood will expand rapidly, and the test products will not be able to resist.

Cook's idea is good, but Cook didn't take into account the absorption speed of the water of life by the demon blood and this test sample, although the demon blood in the body of the test sample that survived after the third injection is very small, but it can't stand the speed of this thing absorbing and devouring life force.

With this discovery, Cook's eyes lit up, because Cook's wood system has a great relationship with the natural system, and Cook's life and death field is the top field, Cook first took out a crystal bottle containing a drop of demon blood, and the death field of the life and death field was activated at once, Cook was completely prepared, and then opened the crystal bottle, when the demon blood in the crystal bottle was shrouded in the death field, the demon blood actually decayed in an instant, becoming a puddle of black water.

"Haha, haha, I understand, this demon blood assimilates the blood of other creatures, in fact, what is assimilated is the vitality of the body. "Assimilating blood and assimilating life force are two different concepts, because blood contains more than just life force.

Devouring life force, this is something that all living creatures can do, plants, and animals, the difference is just the speed of devouring, obviously the blood of this demon has an extremely strong devouring speed.

After thinking about this, Cook felt that his realm of life and death seemed to be comprehended more deeply, and a strange feeling flowed through Cook's heart, Cook closed his eyes and slowly realized it.

Half an hour, an hour, two hours, a full week, Cook has been keeping his eyes closed, and a week later, there was suddenly a trace of green in the original gray death field around Cook's body, and then this trace of green began to grow, this trace of green turned into a small green snake, constantly wandering in the gray field, this green snake kept opening its mouth to suck Cook's death field.

The small snake continued to grow at a speed visible to the naked eye, and finally like a huge swimming dragon, the green snake was actually extremely comfortable in the field of death, Cook slowly opened his eyes, and the green snake shot into Cook's eyes at once after Cook opened his eyes.

Cook's eyes immediately burst into green light, the green light of the two eyes skyrocketed, and two silver crosses shone in the green light, and this silver cross shot a distance of several meters, and the gray death field around Cook suddenly retracted into this silver cross, and the silver cross turned gray, and finally turned into a pitch black color.

After just a few minutes, Cook's eyes did not appear in the slightest, but Cook's eyes were green, and his pupils were black, and he looked no different from before.

"A thought of life and death. Cook whispered four words.

This is the second stage of the realm of life and death, and it is also the second form of the realm, and the first form of the realm is the direct release of the extensive type, surrounding one's body, which is also the origin of the word realm.

The promotion form of the realm is precision control, but this precision control requires a medium, such as hands, feet, and even the heart, as well as the mouth, that is, precision strikes, which can be targeted to strike, unlike at the beginning, no matter where the enemy attacked from, 360 ° around the bodyare all wrapped in the domain, it can be said that the initial domain can be regarded as a defensive stance, and the time is short, Cook is now the second form after the field promotion, it can be said to be an attack form, and it lasts for an extremely long time.

"Raw!" Cook spat out a word softly, and a green light shot out of his eyes, and this green light was directly enveloped in the blood of the demons who were rotted by the power of death in the death realm.

"Huh. But after half a ring, the rotten blood did not recover, but even more rotten, Cook checked and found that there were microorganisms in the rotten demon blood, and the green light emitted by Cook's eyes had a strong vitality, which was absorbed by these microorganisms, so the rotten blood was faster.

"The promotion of this holy realm all depends on comprehension, and this time I actually directly advanced to the second form of the realm, it only took a week. Cook felt that the realm of life and death was now a powerful weapon.

Cook's eyes shot out a black cross light, this light directly hit a poisonous creature at the peak of the holy realm on the other side of the room, this creature was under the illumination of the black cross light, it actually aged at a speed visible to the naked eye, and in less than ten seconds, this poisonous creature died, looking at the shriveled body of this highly poisonous creature, as if it had experienced the baptism of time.

"No, the creature itself eats to replenish its vitality, and this guy was starved to death. But after Cook checked it, he came to another point.

And Cook is also keenly aware that his thoughts of life and death are not affected by the environment at all, which is also very awesome.

Although some of the departments in the special environment, the increase in attack power is very strong, almost reaching dozens of times their original combat power, but it is still the same sentence, there is no perfect strength in the world, this kind of system in another extreme environment, then the combat effectiveness is weakened by hundreds of times.

A line like Cook is good for combat readiness, as it is not affected by the environment.

"Did you touch the Origin Power?" Cook muttered to himself.

Origin power,It's a very special power.,Comprehending the essence of the whole world.,Legend has it that comprehending the essence of the world.,You can have the same lifespan as the whole world.,But this kind of origin power is just a conjecture in the magic academic world.,Maybe someone.,Maybe no one comprehends.,Anyway, it's an unknown.。

Along with the power of the Origin is the power of time, but the conjecture of the magical academic community is that if you want to use the power of time, then the caster with the power of time will also consume its own time power.

For example, if you want to change a person's time magic back to what they were twenty years ago, then you may lose twenty years of time yourself, which is related to a very esoteric theory of balance.

Just like the water of life, it does not appear out of thin air, it is produced by the tree of life, and the tree of life is transformed into water of life by absorbing other substances, and all the balance theories are because no matter where they are, the original balance of matter, like a place being attacked by magic, for a short time the density of a certain magical element in this place is extremely high, but slowly it restores its original appearance, forest fires can burn the entire forest, but these burned forests can no longer provide nutrients for plant seeds buried under the ground for many years, and after countless years, this is a forest again, this is the extremely profound balance theory of the wizarding world。

The theory of balance is used in many places, like strength. Take an ordinary trebuchet as an example, the huge power of the trebuchet smashed on the city wall, this power comes from the trebuchet itself, although the power of the trebuchet comes from the trebuchet itself, but how does the power of the trebuchet itself come from, it is artificial, the trebuchet just plays a conversion role, and the stone projectile smashes on the city wall, the city wall cracks, but the stone bullet itself is also broken, which is also a balance of power.

What is Cook's unaffected environment, that is, a balance point, which is the same in all environments, which is actually finding a balance point in itself, just like the fire system is very powerful in the volcanic environment, but relatively in the snow mountains, the combat effectiveness in the ocean is low, which is actually a balance.

Balance is one of the most esoteric issues in the wizarding world, but for countless years, despite the abundance of examples of balance, no one has really figured out what balance is.

But this is just Cook's feeling, and it still needs a lot of real yàn, and Cook is vaguely sure that he has found this balance.

Now that he has figured out the secret of the demon blood, Cook has to completely solve this problem, and Cook continues to implement the live vaccine on the one hand, but this vaccine also has a certain danger.

Cook wants to start from the blood devouring the life force, Cook does not dare to guarantee that after the success of this vaccine, the guy who is injected with the vaccine will be consumed alive, because even if he eats more things, he will absorb the life force, so what does it mean not to be consumed alive.

But this is just a theory, and the specific situation will not be known until the test is out.

Because theory and practice are often very different, as for such destruction and devouring life force, it is not very complicated, just like destroying the metabolism of cells, Cook has dozens of drugs in his brain that can do it.

And most of it is poison, and the reason why the blood of the demon race lasts for a long time in assimilating highly poisonous creatures is because the toxicity of this highly poisonous creature has such a destructive effect, and what Cook has to do now is to increase the virulence of these highly poisonous creatures themselves, and then enhance the ability of the body of highly toxic creatures to resist toxicity, so as to obtain things like live vaccines.

"Cook, found it, found it. Lina appeared directly behind Cook and said excitedly.
