Villain: In the beginning, the heroine's spiritual pupil is cut out with a knife

Youruo nodded, she had always believed in Shen Yuan's words.

Shen Yuan did not continue the topic about bloodline, but changed the topic and asked.

"When will you demon clan be able to restrain your demonic aura?"

As the name suggests, the demon breath is restrained, which is the ability to restrain one's own demon energy without relying on magic weapons at all.

"Master, different bloodlines of the demon race have different cycles of restraining the demonic breath. A powerful demonic bloodline can restrain the demonic breath in advance. But for a bloodline of the Night Bat clan like me, I am afraid that I can only achieve this by reaching the supreme realm. The demon breath is restrained.”

"Well, let me give you a more vivid example, Master. If it is the nine-tailed spirit fox tribe, they may be able to restrain their demonic aura in half a step, while other races may not be able to do it until they reach the supreme realm."

"So, depending on the bloodline, the cycle of restraining the demonic breath is also different."

Hearing this, Shen Yuan nodded slightly.

"I see."

Just as Shen Yuan was digesting this information, he suddenly felt a stinging pain in his heart, and then a monstrous murderous intention spurted out. In his subconscious, there seemed to be a voice, asking him to kill all life in the world!

"Uh!"

Shen Yuan groaned and clutched his chest tightly. Immediately, the veins on his forehead burst out and his eyes were bloodshot.

Seeing this scene, You Ruo was naturally frightened and panicked. After all, her whole heart was focused on Shen Yuan.

"Master! What's wrong with you?! Master!"

Shen Yuan pushed her away roughly, his voice slightly hoarse.

"But I can't suppress the demonic nature. I seem to have overestimated my own strength. I have tempered the Demonic Bones of Scarlet Blood Princess to perfection, but sometimes I can't suppress the demonic nature of this Demonic Bones..."

As Shen Yuan spoke, he gathered spiritual power in one palm, and then suddenly took a photo of himself!

After spitting out a mouthful of thick blood, Shen Yuan's demonic nature dissipated slightly.

Youruo felt heartbroken.

"Master, when your demonic nature breaks out, do you always use pain to suppress it? Do you suppress it in this self-harming and self-abuse way?"

Shen Yuan was unmoved and didn't think there was anything wrong with doing this.

"This is the easiest and fastest way."

The best way to suppress demonic bones is naturally to use immortal bones to neutralize them, and to use immortality to neutralize demonic nature. This will not only suppress the demonic nature, but also allow immortals and demons to merge into one body.

But unfortunately, for Shen Yuan now, immortal bones are still far away.

He could only rely on this self-destructive method to resolve the demonic nature that broke out.

After doing all this, Shen Yuan's expression softened a little.

You Ruo quickly stepped forward, stretched out her thumb, and wiped away the remaining blood from the corner of his mouth.

When Shen Yuan wasn't paying attention, she put her bloody thumb into her mouth.

"Is my blood really that delicious?"

Hearing Shen Yuan's words, You Ruo was startled. She thought the master didn't notice, but it seemed that she was overthinking.

At this moment, she was like a child who had done something wrong, lowering her head in front of Shen Yuan and not daring to say a word.

However, Shen Yuan didn't mind this.

Youruo becomes more and more fond of drinking blood, which is the result he hopes to see.

This shows that Youruo is likely to evolve from a night bat to a blood bat!

Shen Yuan has read through ancient books and found that no matter what race the monsters are, they all have a probability of evolution.

However, different monster clans have different evolutionary probabilities.

The more powerful the demon bloodline, the higher the probability of evolution.

The best example is the nine-tailed fox clan.

Newly born people of the Nine-Tailed Spirit Fox Clan are not nine-tailed, but one-tailed. Geniuses with relatively high talents will be born with three-tailed tails.

But their evolution probability is very high, and they will evolve during their childhood and teenage years, evolving from one tail to three tails, five tails... and finally nine tails.

You Ruo, the same is true.

She can also evolve, from Night Bat to Blood-eating Bat, Scourge Bat, etc.

However, the probability is very low, very low! Completely compared with the nine-tailed fox clan.

So the current situation is that after the nine-tailed spirit fox clan reaches adulthood, they are basically nine-tailed, while after the night bat clan reaches adulthood, they are still night bats.

In fact, Shen Yuan knew about this when he was reading ancient books when he was a child. At that time, he also conducted an experiment and gave Youruo blood to see if she could evolve into a blood bat.

Of course, blood of poor quality cannot be used, so Shen Yuan used his own blood.

Shen Yuan cut his wrist and asked You Ruo to drink his blood, but the test results were not satisfactory.

Even after drinking a lot of Shen Yuan's blood, You Ruo is still the Night Bat, without any change.

At that time, Youruo blamed herself very much, feeling that she could not do anything well. Even if she drank the blood of her master, she could not complete the evolution of the Night Bat clan.

But Shen Yuan accepted this result calmly.

Because he is not a child of luck and has no luck.

Before conducting the experiment, Shen Yuan had predicted that the probability of success would not exceed [-]%.

However, even if it was a small probability, he had to try.

At that time, Shen Yuan was thinking that if Youruo belonged to Qin Yang's camp, maybe she would evolve successfully.

After all, in the original work, Scarlet Blood Princess's demon bones and Yu Yuehua's fairy bones were both accomplished because of Qin Yang's relationship.

But so what?

Even if there is no luck, Shen Yuan will use any means to plunder luck!

Now, seeing You Ruo becoming more and more fond of drinking blood is a good sign for Shen Yuan.

The sign before successfully evolving into the blood bat clan is an increasing desire for blood.

Especially for the blood of the strong!

After the night bat evolves into a blood bat, it becomes instinct to eat blood.

At this moment, Shen Yuan reached out his hand and gently stroked Youruo's cheek with his head lowered.

"I really hope that one day I can see you transform into a blood bat."

"Eh?"

Youruo raised her eyes. Wasn't the master angry about secretly drinking his master's blood just now?

"Is my blood good to drink?"

Youruo still didn't dare to answer, but nodded anyway.

Shen Yuan retracted his hand, lowered his eyes slightly, and his thoughts seemed to return to the scene of the first experiment.

That time, Shen Yuan drank a lot of blood for Youruo, then asked Youruo if it tasted good, and asked her to answer truthfully.

You Ruo didn't dare to deceive Shen Yuan in the slightest, so she shook her head.

In other words, at that time, Youruo felt that his blood was not delicious.

When he knew this, Shen Yuan knew that the experiment would most likely fail.

After all, the blood bat's instinct is to have a strange desire and yearning for blood.

For blood bats, blood is definitely delicious. The blood of the strong becomes more delicious, as mellow as aged wine!

But if Youruo doesn't think it tastes good, that means she hasn't awakened her blood bat instinct. She hasn't awakened her instinct, so how can she talk about evolution?

But today, when Shen Yuan asked again, You Ruo actually nodded.

"Don't lie to me, is it really delicious?"

Youruo responded quickly.

"You Ruo doesn't dare to deceive the master. This time...well, I do think it tastes good..."
