Si Chen had been immersed in the ancient books, and he didn't notice that the moment he opened his eyes, the ethereal figure behind him disappeared in an instant, leaving behind a bird hovering in the air covered in red feathers.

It's just that at this moment, Ah Yu's previous state is completely opposite, and now Ah Yu seems to have become a lot more tired in an instant, and his body is not as solid as before.

After Si Chen fixed his eyes, he turned his head to look in Ah Yu's direction.

Si Chen had been immersed in his sea of consciousness before.

Regardless of whether a person can cultivate or not, as long as the living beings on this continent have a sea of consciousness that only belongs to him in the inner dantian.

It's just that some people who can't embark on the path of cultivation for the rest of their lives, even if they know that they have the existence of the Sea of Consciousness, they can't concentrate their attention like this.

This is because cultivators cultivate not only the body, but also the soul.

Only a person's soul is strong enough to be able to feel the existence of the sea of consciousness, but their soul can only go deep into their own sea of consciousness and can probe in their own body, and they can't rely on the power of innate cultivation to get their soul out of their body, unless the cultivator relies on some special methods that have been circulated in the world, or an ancient beast clan that exists at a perverted level like Ah Yu.

This place seems virtual, it seems invisible.

The Sea of Consciousness is also the foundation of a cultivator.

In many cases, the level of an individual's cultivation does not only depend on the level of his retail sales, but there are too many factors that determine the level of a person's cultivation.

And the sea of consciousness is one of the most important factors.

In that vast and boundless space, Si Chen always followed a mysterious voice, followed the guidance of the voice that kept emerging in his mind, and went deep into the ancient books step by step.

It's just that in this process, I don't know what kind of mistake has occurred, which will cause the dilemma of qi and blood flowing backwards and making it difficult to breathe.

But fortunately, Ah Yu discovered his anomaly in time.

Before, Si Chen always followed the voice in his head, constantly forming complex handprints in his hands, and at first he was a little wary of this voice, but later he found out that this voice was teaching him the way to cultivate the Xuan Soul Illusion.

Later, Si Chen also relaxed his vigilance against this voice, but he didn't expect that if he was not careful, he would strayed into the trap of an ancient book, perhaps the trap of the person who created this ancient book.

Originally, very few people were able to truly comprehend the content of the exercises written in such a continuous way, and individuals even left a small conspiracy in their own exercises.

If it weren't for Ah Yu today, I'm afraid I would have fallen into the trap of this ancient.

As soon as he thought of this, Si Chen couldn't help but say, 'Damn, I actually let a person who has passed away and doesn't know how many years have been tricked.' '

But then think about it, presumably this person took great pains to create this ancient book in the first place, hoping that the person who inherited it would be a dedicated person who was always vigilant.

However, after Si Chen calmed down, he frowned after seeing Ah Yu's appearance.

The bird looked very tired, and the whole figure became very ethereal, as if it would disappear into the world in the next moment.

Si Chen remembered that before he stepped into the sea of consciousness, Ah Yu's form was much more condensed than now.

Si Chen is naturally not stupid, he had already fallen into the trap left by this ancient book when he was in the sea of consciousness before, and there was no way back at all.

At that time, the feeling was suffocation, the profound qi and blood retrograde, and the feeling of death was gradually approaching, so that Si Chen had no way to think at all, and there was no way to study the sudden appearance of this situation in his body, because he did not give Si Chen any chance to think about it at all.

However, when Si Chen thought that he was finished, he would be buried here when he practiced the first exercise.

Unexpectedly, in the last few seconds of life and death, a strong breath forcibly opened his sea of consciousness and dragged himself out of the predicament.

And that strong aura, which Si Chen didn't notice, was Ah Yu.

You must know that all living beings in the world are born from souls, and if there is no soul, then this living beings are no different from death.

So the soul is the most fragile and strongest thing in a person. As a practitioner continues to improve his cultivation, his soul's willpower will also increase.

The growth rate of consciousness is very slow, some people are born with strong soul power, but some people are born with very weak soul power.

Some of the people in this world who are considered to be masters cannot place their souls in the sea of consciousness of others, because this thing is an extremely dangerous thing, and if you are not careful, your soul will be lost in the sea of consciousness of others, and you will become a walking corpse.

When Si Chen saw Ah Yu, whose face looked very tired at the moment, he was a little speechless for a while.

In my heart, I said that I was not moved in the slightest, but it was false.

Even from the beginning, Si Chen knew what Ah Yu's purpose was for accepting him as an apprentice.

Si Chen has never been a fool, on the contrary, he is a meticulous person.

From the moment Ah Yu drank his first mouthful of blood, Si Chen was able to guess something, no matter what kind of effect his blood had, anyway, it was like a panacea for this bird.

But now seeing that Ah Yu's soul is now illusory as if it will disappear in the next second, Si Chen's expression moved, it originally accepted itself as an apprentice just to find a long-term blood bag, but if it died, it could completely drain its own blood, but it risked that its consciousness would always be sealed in its own consciousness forever, and it did not hesitate to save itself.

"You're in luck, boy. Originally, I thought it was a book of exercises without grade, but now it seems that it is far more than that" Ah Yu wants to make himself look less tired, the corners of his mouth are raised, and he is still a little weak when he speaks, and now that he is like this, he still has the energy to joke Si Chen.

Ah Yu, I think the apprentice I just accepted, just because I can only recover the aura of these Weibo now, and I have any look down on myself.

This book does not mark any grade of exercises, Ah Yu has never taken it to heart for so many years, and he has not even opened it.

Among all the gifts received, this parchment scroll was the most inconspicuous, and it was not directly thrown into the most inconspicuous corner by Ah Yu.

"Take care of yourself first!" When Si Chen saw that Ah Yu was very tired, but he still had to show a far-fetched smile in front of him, Si Chen's heart was surging, and he didn't know what he was thinking.

Immediately afterwards, as if he remembered something, Si Chen groped directly on his body, and finally found a dagger on the right cuff.

This dagger was when he was in the Yudian before, and he didn't find any tools that could be used to cut herbs, so Si Chen casually took a dagger that could be regarded as handy.

Si Chen took the dagger directly, and without hesitation, he slashed it on his left arm.

Immediately after that, a blood mark slowly turned crimson.

"You!" Ah Yu didn't expect Si Chen to be so cruel to himself, he didn't say a word, and directly slashed his arm fiercely, without blinking his eyes.

Ah Yu was stunned for a second before he realized that at this moment, Si Chen looked at the words contained in his expression.

He knew how important his blood was to him.

But even so, he chose to become his apprentice.

Now such a move directly made Ah Yu stunned in place.

In fact, it was just that he had just gone deep into Si Chen's sea of consciousness and spent a lot of energy, but in fact, it would be good to rest for a few days.

For many years, Ah Yu can only live here, in this sealed place.

But most of the time the soul will inhabit the bead at the bottom of the lake, this whole lake is the source of the seal, where the purest aura is gathered, and it is here that Ah Yu, who has only a few wisps of gossamer, can continue to return to his original form, but although it has been so long, it has only returned to such a small form now, and over time, he has slowly recovered his memory of the past.

"What are you doing in a daze, drinking?" Si Chen raised his injured arm at Ah Yu's thoughts.

Si Chen noticed that Ah Yu was now stunned in place.

I have to say that there seems to be a mysterious power in the blood of the brain, which makes Ah Yu addicted to it just by drinking it once.

But at this moment, since Si Chendu had already broken his arm and was waiting for him to go over and drink, Ah Yu had no choice but to go over and drink two sips.

In the process of slowly leaning towards Si Chen, Ah Yu really sighed, I don't know if I should accept this apprentice, although the blood of this little apprentice can help him improve his soul strength and shorten the cultivation time a lot, but this little apprentice is also very uneasy.

Ah Yu has been here for tens of thousands of years, and for tens of thousands of years, he has spent every day and night by himself, and suddenly a person always likes to quarrel with himself on the surface, but when he is in danger, he will help himself as soon as possible.

This kind of warmth that has never been felt in the need makes Ah Yu not know whether to be happy or unhappy.

However, after drinking Si Chen's blood this time, it still takes a certain amount of time to digest, after all, there are too many majestic powers in the god-level bloodline, plus Si Chen has been under the control of the seal, the power in this blood seems to be even stronger, and it seems that there is a move to break through the seal.

But I hope that it is not as Ah Yu imagined, if that moment really comes, then the only thing he can do is to keep challenging himself and avenge himself before that moment comes.

But to be honest, although Ah Yu had also drunk his own blood before, he had never observed her at close range like this, only to find that there was an inexplicable sadness in her expression.
