Three days later, after finishing the morning's practice, with the maid Barbara, Gray went to the library on the second floor of the castle.

Not surprisingly, Caroline was already in the library.

Today, she is wearing a light blue short-sleeved long skirt, revealing a pair of slender and white hands, her long brown hair is tied into a ponytail by delicate hair accessories, and with an elegant sitting posture, the temperament of the aristocratic lady is undoubtedly revealed.

She held a book in her hand, a teacup beside her, and behind her was a maid dressed in black and white, waiting quietly.

Seeing Gray coming, she raised her beautiful blue eyes, smiled slightly, and pushed the purple leather book "Bloodline Catalog" in front of Gray, and said.

"I've finished reading this book, thank you!"

"No, you don't."

Gray took it and asked.

"What do you think of this book?"

"Very interesting insight, although the evidence of the argument is different from the bloodline evolution of "Origin of Species", it also proves that there is a bloodline connection between low-level blood beasts and high-level blood beasts."

Caroline replied after a moment's thought.

"And this book is more detailed than "The Origin of Species", which is very valuable for those who want to understand blood beasts."

"I can get such a high evaluation from Sister Caroline, then I look forward to it even more."

Gray smiled slightly, sat down in the chair opposite Caroline, asked the maid Barbara to make milk tea, served pastries, and began to flip through the front pages of the book.

Last time, because of the rush of time, he only had time to flip through the title page, and he didn't even read a page of the main business.

"Bloodline deterioration, a phenomenon or rule that exists universally among blood beasts, in my opinion, it is precisely because of its existence that the blood warrior has the possibility of upward promotion, he is simply the gift of the 'mother of all things' to the weak human body."

"As we all know, bloodlines are corrosive and mutually reinforcing, and the higher the level of bloodline, the stronger the degree of erosiveness and mutual exclusion."

"A person who implants the bloodline of a blood beast for the first time, if he implants the bloodline of a high-level blood beast, the most likely result is that because of the strong corrosive nature of the bloodline of the high-level blood beast, he dies or becomes a half-human and half-beast without reason."

"Therefore, the bloodlines that can be implanted by people who are implanted with blood beast bloodlines for the first time are often the lowest-level fierce blood beast bloodlines."

"This has caused another problem, after implanting the bloodline, the person already has the blood beast bloodline in the body, and when he wants to implant a higher-level blood beast bloodline again, it stands to reason that the bloodline will be rejected, after all, it is the bloodline of different blood beast species."

"But if you can't continue to implant a higher-level bloodline, your strength will obviously not be improved, and you will be at a low-level stage for the rest of your life."

"And the deterioration of the bloodline perfectly solves this point, as if it exists to solve this point, although it is the bloodline of different blood beast species, but after all, the former is formed after the deterioration of the latter, so the latter has perfect tolerance for the former, and there will be no bloodline mutual exclusion."

"There will be no mutual exclusion of bloodlines, and if a higher-level bloodline is implanted, it will naturally be able to ascend again......"

The continuous pages are full of analysis and insights on the deterioration of the bloodline, and the insights are very unique, which makes Gray refreshed and has a clearer understanding of the blood warrior cultivation system in this world.

Subsequently, the detailed narration of the sequence from low-level blood beasts to high-level blood beasts began one after another.

The first sequence to be told is the tailed fox sequence.

The lowest level is the tailed fox, which is a fierce blood beast with average strength and defense, and its speed can only be ranked in the middle of the stream.

In terms of physical characteristics, the strength of the tailed fox is really average, and basically most fierce blood beasts can completely abuse it, but in fact this is not the case.

Its Blood Beast ability is called "Hallucination", a strange ability that can cause the object it sees to fall into a hallucination, and yes, its Blood Beast ability does not affect the body, but the spirit.

This kind of attack from the spiritual level can be said to be unguardable, even if you have defense, it is difficult to dodge, and in battle, it is like standing in place to attack others, which can be said to be extremely deadly.

With this ability, the tailed fox can be called a hegemon among the fierce blood beasts, even the iron-armored rhinoceros dares to provoke, after all, the iron-armored rhinoceros is strong in physical defense, not mental, as long as it is hit by its "hallucination" ability, it will also fall into sluggishness.

Of course, with the strong defense of the iron-armored rhino, even if it falls into sluggishness and distraction, the tailed fox has nothing to do with it.

Further up are the two-tailed fox, the three-tailed fox, the four-tailed fox, and finally the five-tailed fox whose strength is comparable to that of a king-level warrior.

The ability is also a "hallucination" ability, but the effect of this "hallucination" is gradually enhanced by terror, especially the five-tailed fox, which is even more terrifying enough to be able to kill the target spirit directly through the hallucinogenic ability.

The physical body is intact, but the spirit is dead, and the most important thing is that this ability is difficult to guard against, and Gray shuddered at the thought of this.

The second one to be told is the bronze lizard sequence, and it is worth mentioning that the copper lizard is up, and the blood beast whose strength has reached the desolate level is the copper-backed dragon lizard that Gray has heard of.

The third one to be talked about is the Mighty Bear sequence, which is characterized by its great strength and the ability to manipulate gravity as a blood beast.

Their great strength gives them extremely destructive power, and the ability to manipulate gravity can help them slow down the enemy's movement speed, and this sequence of blood beasts is also extremely difficult to entangle among blood beasts of the same level.

The fourth one that was talked about was a snake, a blood beast of the fierce level, and the blood beast ability it possessed was one of the ten attributes of earth, fire, wind, thunder, ice, shadow, water, poison, wood, and gold, which means that at the lowest level of this sequence, there were a total of ten blood beast species.

The Shadow Serpent that Gray had encountered before was one of the ten blood beast species.

And after going up, the number of heads will increase in turn, and the abilities mastered will also increase one by one, and the strongest in the sequence is the five-headed snake, with five heads, five blood beast abilities, and its strength has reached the king level.

At the same time, the author, the man who called himself Porcis, made a bold guess.

There may be a hydra with a higher number of heads, or even a decada with ten heads.

If this kind of high-level blood beast really existed, he estimated that this kind of blood beast was likely to be a legendary saint-level or even god-level blood beast.

……

Flipping back one sequence after another, Gray watched with relish.

The blood beast is a magical species, and it is also a unique species, if there is any species that is most spoiled by the "mother of all things", it is definitely the blood beast.

With a thousand strange abilities, it can be called a special person among the species, and the gap with other species is like the gap between the abnormal person and ordinary people, no wonder this continent was a long time ago, and human beings could only be reduced to blood beasts of blood beasts.

Fortunately, with the advent of the blood method, human beings can get rid of the miserable situation of being reduced to blood food, and gradually be able to compete with blood beasts.

"Sure enough, there is ......"

Continuing to look down, when he saw the twenty-third sequence, Gray couldn't help but feel refreshed and more focused.

This is the Wind Wolf sequence, that's right, this is the one where the blood method that Gray is cultivating right now is.

Gray finally saw the name of the blood beast after the Wind Wolf, the Wind Wolf.

According to the book, this is a blood beast whose strength is comparable to that of a berserker, compared to the wind wolf, the ability of the blood beast to manipulate the wind has been enhanced, the power of the wind blade is stronger, and it can manipulate multiple wind blade attacks at the same time.

Thinking about it, the blood beast bloodline implanted in Viscount Fergus's body now should be the bloodline of this blood beast.

"After the storm wolf is the wind wolf, after the wind wolf is the storm wolf, and after the storm wolf is the storm wolf king."

Gray continued to look down, and when he saw that the strength of the Storm Wolf King at the end of the sequence was already comparable to that of a king, he breathed a sigh of relief.

For a long time, he had a worry, that is, the implantation of the blood beast bloodline in the follow-up after the strength reached the berserker blood warrior.

Viscount Fergus's expectation for him is to reach the strength of the Berserker and lead the Fergus family to become the Earl Family, but with the ability to "transform", his ambition in his heart is not limited to the Berserker.

He also wants to be stronger, and even wants to become the strongest in this continent, after all, he has the ability to "transform", and he has such a possibility.

However, after all, the Fergus family is only a viscount family, and it is likely that there is no follow-up blood method after the berserker, and they don't know what kind of blood beast essence needs to be used in the follow-up, what kind of drug formula needs to be matched with it, and what kind of blood method is used to support cultivation.

Now, he knows the name of the follow-up blood beast, and with the ability to swallow the blood of the blood beast, absorb the characteristics of the blood beast, and obtain the ability to transform, he has a certain certainty that he will continue to progress without implanting bloodlines and blood methods, and has the hope of reaching the king-level warrior.
