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

Shen Yuan didn't continue the topic about bloodline, but asked in a different topic.

"You demon clan, when can you be introverted?"

Demon breath introverted, as the name suggests, is to be able to restrain one's own demonic energy without relying on magic weapons at all.

"Master, different demon bloodlines have different cycles of introverted demon breath. The powerful demon bloodline can be introverted in advance. And the bloodline of the Night Bat clan like me, I'm afraid that only by obtaining the Supreme Realm can I achieve demonic breath and restraint. ”

"Well, let me give the master a more vivid example, if it is the Nine-Tailed Spirit Fox Clan, they may be able to achieve demonic restraint in half a step, while other races may only be able to do it in the Supreme Realm."

"Therefore, the bloodline is different, and the cycle of introverted demon breath is also different."

Hearing this, Shen Yuan bowed slightly.

"I see."

Just as Shen Yuan was digesting this information, he suddenly felt a tingling pain in his heart, and then a monstrous killing intent gushed out, and subconsciously, as if a voice appeared, asking him to slaughter all the lives in the world!

"Ugh!"

Shen Yuan snorted, covered his chest tightly, and immediately the green tendons on his forehead exploded, and his eyes were bloodshot.

Seeing this scene, Youruo was naturally frightened and panicked, after all, her heart was all on Shen Yuan.

"The hosts! 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 overestimate my own strength and refine the demon bone of the Red Blood Ji to the extreme, but I, sometimes I can't suppress the demonic nature of the supreme demon bone......"

Shen Yuan said, condensed spiritual power with one palm, and then suddenly slapped it at himself!

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

Youruo was distressed.

"Master, when your demonic nature erupted, was it forcibly suppressed with pain? Suppressed in this self-mutilating and masochistic way? ”

Shen Yuan was unmoved, and didn't feel that there was anything wrong with doing so.

"It's the easiest and fastest way to do it."

The best way to suppress the demon bones is naturally to neutralize the demon nature with the immortal bones and neutralize the demon nature with the immortal nature, so that not only can the demonic nature be suppressed, but also the immortal and the demon can be combined.

But it's a pity that for the current Shen Yuan, the immortal bones are still far away.

He can only rely on this self-inflicted way to dissolve the demonic nature of the outbreak.

After doing all this, Shen Yuan's complexion really eased a little.

Youruo hurriedly stepped forward, stretched out his thumb, and wiped away the remaining blood stains from the corners of his mouth for him.

Taking advantage of Shen Yuan's lack of attention, she sent her bloodstained thumb into her mouth.

"Is my blood really that good?"

Hearing Shen Yuan's words, Youruo was startled, thinking that the master hadn't noticed, and it seemed that he was thinking too much.

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

However, Shen Yuan didn't mind this.

Youruo became more and more fond of drinking blood, which was the result he wanted to see.

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

Shen Yuan has flipped through ancient books, no matter what race the demon race is, it has a probability of evolution.

It's just that different demon races have different probabilities of evolution.

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

The best example is the Nine-Tailed Spirit Fox Clan.

The person who was just born in the Nine-Tailed Spirit Fox Clan is not a nine-tailed, but a one-tailed, a genius with relatively high talent, and he will be a three-tailed one at birth.

But they have a high probability of evolution, and they will evolve from one tail to three tails and five tails during their childhood and juvenile years...... Until the last Nine-Tails.

The same is true of Youruo.

She is also able to evolve, from the Night Bat to the Blood-Eating Bat, the Scourge Bat, etc.

It's just that the probability is very low, very low! Completely compared to the Nine-Tailed Spirit Fox Clan.

So the current situation is that after the nine-tailed spirit fox clan becomes an adult, it is basically a nine-tailed, and after the night bat clan becomes an adult, it is still a night bat.

In fact, Shen Yuan knew about this when he was a child when he was looking through ancient books, and at that time he also did an experiment to drink blood to Youruo to see if she could evolve into a blood bat.

Of course, you can't use blood that is too poor quality, so Shen Yuan uses his own blood.

Shen Yuan cut his wrist and made Youruo drink his blood, but the test results were unsatisfactory.

Even after drinking a lot of blood from Shen Yuan, Youruo is still a night bat, and there is no change in the slightest.

At that time, Youruo complained very much about herself, feeling that she couldn't do anything well, even if she drank her master's blood, she couldn't complete the evolution of the Night Bat Clan.

But Shen Yuan accepted this result calmly.

Because he is not a son of luck, and there is no luck to add to it.

Before conducting the test, Shen Yuan had expected that the probability of success would not exceed half percent.

It's just that, even in the slightest probability, he has to try.

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

After all, in the original book, the demon bone of the Red Blood Ji and the immortal bone of Yu Yuehua were both made possible because of Qin Yang's relationship.

But so what?

Even if there is no luck, Shen Yuan will do whatever it takes to plunder luck!

Now, seeing that Youruo likes to drink blood more and more, it is a good sign for Shen Yuan.

The sign before successfully evolving into the Blood Bat clan is that there is an increasing desire for blood.

Especially for the blood of the strong!

After the night bat evolves into a blood bat, it will become instinctive to eat blood.

At this moment, Shen Yuan stretched out his hand and gently stroked the cheek of Youruo, who had his head down.

"I wish I could see you turn into a blood bat one day."

"Huh?"

Youruo raised his eyes, just now he stole the master's blood, and the master was not angry?

"Does my blood taste good?"

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

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

That time, Shen Yuan gave Youruo a lot of blood, and then asked Youruo if it was good to drink, and asked her to answer truthfully.

Youruo didn't dare to deceive Shen Yuan in the slightest, so he shook his head.

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

When he knew this, Shen Yuan knew that there was a high probability that the experiment would fail.

After all, the instinct of the blood bat is to have a strange desire and longing for blood.

For blood bats, blood must be delicious, and the blood of the strong will become more and more delicious, as mellow as aging!

But if you don't think it's delicious, it means that she hasn't awakened the blood bat instinct, and the instinct hasn't awakened, so how can she talk about evolution?

And today, when Shen Yuan asked again, Youruo actually nodded.

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

Youruo quickly responded.

"You Ruo didn't dare to deceive the master, this time...... Well, I do think it's delicious......"
