As soon as Song Xingtian's chatterbox was opened, he talked very excitedly and talked endlessly: "All kinds of plants, trees, beasts, and utensils are nourished by the aura of heaven and earth, and among them, those who are special in their understanding stand out and transform into demons.

The lifespan of human beings is only 100 years, and the lifespan of wood, beasts, and utensils is uneven. In comparison, the life span of the demon is extremely long, and the so-called thousand-year-old spirit crane and 10,000-year-old spirit turtle even have the remnants of a 100,000-year-old beast.

A hundred years of time, as far as the demon is concerned, it is really not worth mentioning. In a sense, demons can almost be called immortal, but they can't live as long as the sky.

The funny thing is that the human race is seeking up and down for immortality, but the demons who are already immortal give up their longevity and ignore it, only to cultivate desperately, and do everything possible to turn into human form, and gradually there are demon clans one by one. Today's demon world is occupied by the major demon clans. ”

Li Yu was surprised: "Why do demons have to turn into human form? Why does the divine doctor say that they have given up immortality? Is there a difference between a demon clan and a demon?"

"Everything in heaven and earth has its own spirit, for example, a cat barks when it is hungry, and a dog can distinguish between its owner and its guests. The spirituality of the demon is even more outstanding, far superior to ordinary beasts, and it has accumulated demonic power because of its long-term survival, and its power is terrifying.

For this reason, cultivators often surrender to demon beasts for their own use, all the demon beasts in the Royal Beast Gate, the blue water Xuanhe in the Yuquan Sect, and the god-eyed spirit monkey in the 'Exploration Hand' Sikong Xuan Bag are all clear evidence of the human race's enslavement of demons.

Although the demon has wisdom, although he knows what is good or bad, but it is out of intuition by nature, even if the demon is strong, on conspiracy and trickery, on false benevolence and false righteousness, on the combination of vertical and horizontal, how can it be the opponent of the human race?

In the era of ignorance, a large number of demon beasts were driven by human races, and their status was no different from that of poultry and cats and dogs, or even slightly inferior. During this long period of darkness, the demon experienced all kinds of pain. For them, they would rather live freely than this enslaved 'eternal life'.

It is precisely with the companionship of the human race day and night that many intelligent demons have secretly learned the language and writing of the human race, learned the way of thinking of the human race, learned the cultivation methods of the human race, and created a unique body suitable for demon cultivation. Gradually, one by one, the demons metamorphosed and became humans.

The reason why the demon beast turned into a human form was because he subconsciously felt that man was the most powerful existence, and secondly, because a large number of cultivation techniques in the early stage were only suitable for the human body and not for the demon body, so it was a last resort. There are many things to demonize people, and it has gradually become a custom, which is a matter of course.

These demons who can transform into shapes multiply in groups, and their power gradually expands, becoming entrenched demon clans one by one, gradually seizing a large part of the territory of the human race, and finally opening up the territory of the demon world.

Of course, what interests the old man the most is that once demons incarnate into humans, their lifespan is no different from that of humans, even if they are demon kings and demon emperors, they can't live for a hundred years!

The same demon, just in the transformation of the demon body and human form, the lifespan is drastically reduced, is it really the restriction of the Heavenly Dao on the human race? Perhaps, it is because the human race is too smart and excellent, so the Heavenly Dao, or those high-ranking Da Luo Jin Immortals, have to be checked and balanced.

And the demon clan that turned into a human, although its descendants all lost the advantage of longevity, they also gained all kinds of benefits. For example, the offspring born to the demon clan can transform the demon body and human form at will, and they can read and write like the human race, and communicate with each other.

In other words, the descendants of the demon clan don't need to be as one out of a thousand as their ancestors to easily gain wisdom. It is precisely because of this that the demon race has been able to rise and be able to compete with the human race for thousands of years and stand tall. ”

When Li Yu heard this, he secretly said: "I only said, 'If you are not of my race, your heart will be different', but it turns out that you still have such an inside story. According to this, the demon beast can only be regarded as a non-human genus, and the demon clan can already be counted as the same kind of human race.

No wonder Tang Rouyu didn't think about me being a demon body, and even Sister Yue'er didn't have any mustard. The snail girl, the white snake, the fox girl and many other demon clans they talked about were also able to walk in the fairy forest openly and honestly because of this, and they were not killed by the fairy forest. ”

Song Xingtian looked at Li Yu with deep meaning, and continued: "And another advantage is that the demon power of the demon clan can be inherited by blood. In other words, as long as it is a person of the demon clan, he has inherited part of the demon power of his parents from the first place. The stronger the parents' own demonic power, the higher the demonic power inherited by their children.

That's why the old man wants you to be bloody. Ordinary people of the demon clan have weak demon power and thin ancient demon blood, so they don't have much research value. And your blood is very different, which is an important part of the old man's research.

The Nine Turns is one of the three major royal families in the demon world, and the strength of the demon is needless to say. Your blood contains the vast demonic power of the Foxy, and it also retains the blood transformation of the ancient Foxy Demon after it was transformed into a human, which will help the old man find out the secret of the disappearance of the effect of immortality on the demon clan.

I forgot to mention that there is actually another reason. Your blood is not just blood, but contains both human and demon blood. In other words, you are born of the union of man and man.

The difference and integration between humans and demons are vividly demonstrated in your blood, and for the old man, your blood is a peerless medicinal material that can be encountered but not sought, and the natural charm is endless. ”

Li Yu was shocked, and the strange and familiar beautiful face suddenly appeared in his mind, and he couldn't help but think: "Is she really my mother? Song Xingtian is not like a person who talks nonsense, am I really the son of a man and a demon? So is my father a demon? Or is my mother a demon? Why do they abandon me? Could it be that as Tang Rouyu said, there is still a secret behind it?"

But saving Zhao Yue'er's life at this moment is important, but it is not the time to think deeply. Li Yu hurriedly stopped his reverie, tried his best to regain his composure, and said lightly: "Thank you for telling the divine doctor." Now, I can accept the blood collection ceremony with peace of mind. ”

"The old man hasn't said a long story for a long time. Perhaps, the old man was deeply infected by your courage, and felt that you could really escape death, and even thought that you could help me complete a more important experiment. Leave it alone, you come with me. ”

Li Yu followed Song Xingtian to the next room, but he felt a strange smell, but he saw that the medicine jar was heavy, and there were many medicinal materials and inner pills stacked on the shelf.

In the blink of an eye, Song Xingtian was already holding a sharp knife in his left hand and commanded: "Take off your clothes and lie on that couch." In order to preserve it freshly, the old man will cut through the blood veins all over your body, and the blood in each vein will flow into the closed medicine jar through a special small tube. If these ten medicine jars are not stored, the old man will never stop the knife in his hand. ”

Li Yu did as he said, although he could hear the sharpening of the knife in his ears, he was not afraid of it, and smiled: "The divine doctor can perform the knife." ”

"Don't be in a hurry. The old man has hemp boiling, and when the knife is used to extract blood, it can make you fall asleep without any pain. But if you lose too much blood, once you fall into a coma, your consciousness will collapse, and you can't sleep, and the gods will be difficult to save.

If you don't take Ma Boiling Powder, as long as you can stay conscious when you finish taking blood, the old man can save your life. It's just that this glimmer of life is just a fake life.

All ten pots were filled with blood, and it would take about four hours. No one in this world has survived the trauma of blood loss all over his body for a long time, at least, the old man has never heard of such a person with iron bones.

Whether to take it or not, you can choose by yourself. But according to the old man, it is better to sleep to death than to die in pain, so why bother yourself?"

"Sleeping to death is really dying, and dying of pain is just a description, so I naturally choose not to accept numbness. ”

Song Xingtian sighed: "You are so indifferent, but it makes the old man look forward to it a little more." It's a pity that the pain of Ling Chi and the pain of blood loss can't even be endured by an iron man. Can you really take it?"

"Try it and you'll see. Li Yu definitely didn't even let out a cry of pain. ”

"The old man wants to believe you, but he doesn't dare to believe you. Now that you have made up your mind, you have eaten this 'soft tendon pill'. First unload your whole strength, so as not to be in pain, stretching and kicking, but to disturb the old man's affairs. ”
