The energy contained in the eight-star soul spirit stone was very huge, and Yi Chen was not going to use it originally, but according to the current situation, if he didn't use it, it would be difficult for his cultivation to enter the middle level in a short period of time.

Reluctant to let the child trap not find a wolf, Yi Chen did not hesitate at all, quickly put the eight-star soul spirit stone in front of him, pinched the magic with both hands, and mobilized his soul power to punch into the eight-star soul spirit stone.

"Huh"

With the support of some special energy, the eight-star soul spirit stone rose into the air, and the soul power of the extreme purity poured into the stone, and the powerful fluctuations made the surrounding space vibrate.

The strong suction power penetrated out of Yi Chen's pores, and the powerful soul power was continuously absorbed by Yi Chen, because the number was too large, Yi Chen felt that the pores were painful, and even the meridians were swollen and painful.

Using a high-star soul spirit stone to directly rush to the stairs is very dangerous, Yi Chen's move can be said to be very crazy, but he didn't hesitate at all, and directly introduced that soul power into the beast soul.

With the huge energy infusion, the little space left in Yi Chen's beast soul was instantly occupied by a huge soul power, and a strong feeling of swelling spread throughout his body.

Don't dare to be a little sluggish, Yi Chen controlled the beast soul, constantly compressing the soul power contained in the beast soul, and at the same time, the flames in the stone spirit seemed to sense a huge amount of energy, and also began to absorb the soul power.

Ever since it subdued the flames, it had been staying in the beast soul, and whenever Yi Chen cultivated, it would absorb a small part of its soul power.

At this time, in the face of the huge soul power, the absorption of the flames could be said to be very small on the whole, and it had no effect on Yi Chen.

However, at this time, Yi Chen hoped that the flames could absorb more, so that he would not have to suffer so much. The sharp pain that came from the beast soul made him sweat all over his body.

But compared to these, Yi Chen was more worried about something. Because the speed of refining was not fast, but the speed of soul power pouring in was extremely fast, Yi Chen's beast soul gradually swelled.

This situation, when Yi Chen forcibly broke through in the past, he had encountered it several times, and he was very familiar with this situation, if he didn't stop in time, the beast soul had a great chance of being blown up.

Although he knew that there would be such a danger, Yi Chen did not stop, and he was still absorbing soul power, which was extremely crazy.

Of course, Yi Chen didn't stop, and there were reasons for him. There have been such situations in the past, but every time Tianshu will come out to solve the siege, and then he will be able to advance smoothly.

Therefore, Yi Chen wants to try it now, to see if such a crazy absorption, if Tianshu senses danger, will he come out to help him out of the siege.

With such an idea, Yi Chen was frantically absorbing soul power, and his beast soul swelled up like a leather ball, and it became bigger and bigger, and his abdomen gradually bulged.

The intense swelling pain almost made Yi Chen faint in pain, he forcibly endured the pain, mobilized a trace of soul power, and observed the book of heaven in the storage ring, but found that the book of heaven was lying in the storage ring without any movement.

"Hurry up!" Yi Chen's voice sounded in his heart, and he stared at the Book of Heaven, expecting it to change.

But waiting didn't pay off, when half of the energy of the eight-star soul spirit stone was absorbed, Yi Chen's beast soul had already swelled like a leather ball.

Fortunately, Yi Chen's beast soul is more special than other demonic beast souls, otherwise he would have been exploded by that huge soul power.

"Hum. Finally, when Yi Chen was about to take it back, the beast soul trembled slightly, and then the heavenly book that stayed quietly in the storage ring seemed to sense the danger and flew out of the ring in an instant.

A dazzling light seeped out from the Book of Heaven, and it floated above Yi Chen's head, enveloping Yi Chen in it.

At this moment, Yi Chen's spirit was shocked, and then the beast soul was like a heart, constantly beating and contracting, and the soul power contained in it was strongly oppressed and began to surge violently.

Under the squeeze of the beast soul, the huge soul power was constantly compressed, and all the impurities in it were eliminated, and the soul power, which was already very pure, became more and more pure.

In the process of refining, the soul power contained in the eight-star soul spirit stone did not stop outing, and was continuously injected into Yi Chen's body.

"Click" I don't know how long it took to absorb it, and suddenly, a piercing sound came out of Yi Chen's beast soul, as if it had broken the shackles of some kind of restraint, and the space of the beast soul had grown sharply.

"Succeeded!" Sensing the change in the beast soul, ecstasy appeared on Yi Chen's face, there was no doubt that he had already entered the middle level of the Yellow Soul Realm!

"Huh" An even more terrifying soul power came out of the beast soul, and the soul power contained in the eight-star soul spirit stone was inhaled into Yi Chen's body more quickly.

The amount of soul power was too large, and the space that Yi Chen had just vacated was filled again, and the beast soul beat like a heart again, compressing the huge and complex soul power.

Time passed, and after half a quarter of an hour, the soul power in Yi Chen's beast soul had become extremely pure, and it was difficult to free up any space.

"After such tempering, as soon as you advance to the mid-level beast soul, you will reach the bottleneck stage of the Yellow Soul Realm in an instant!" Sensing the situation of the beast soul, Yi Chen muttered lightly.

Now, he only needs to encounter an opportunity to be able to enter the high level of the Yellow Soul Realm.

If it continues to absorb, there is no point in it, Yi Chen is ready to cut off the magic trick and stop absorbing it.

However, just when Yi Chen pinched off the spell, something very strange happened, although he cut off the spell and stopped releasing suction in his body, the soul spirit stone was still floating in the air, seeping out soul power.

"What's going on?" Yi Chen encountered this situation for the first time, and he felt very puzzled.

At this moment, the Heavenly Book floating above his head trembled slightly, and then released an extremely strong suction, continuously absorbing the soul power of the eight-star soul spirit stone.

"Tianshu actually absorbs soul power, how can this be?"

It had been a long time since he had obtained the Book of Heaven, but it had absorbed soul power, and it was the first time that Yi Chen had seen it, and his eyes widened in an instant, a little incredulous.

The golden light came out from the Book of Heaven, Yi Chen stood up with a puzzled face, stepped forward to observe the Book of Heaven, and at the same time stretched out his hand and grabbed it towards the Book of Heaven.

Just when Yi Chen grabbed the Book of Heaven with his hand, something incredible happened, only to see a dazzling golden light coming out, which made Yi Chen's eyes tingle and squint his eyes in an instant.

At this moment, Yi Chen felt a strong suction force coming from the place where his hand was grabbing, and he felt that his body was sucked away.

The dazzling light quickly dissipated, and when Yi Chen opened his eyes again, there were some familiar scenes in his eyes, which made him slightly stunned. It's dark, and it's covered in mysterious patterns.

Although he came to this place, Yi Chen did not feel the slightest nervousness, and it seemed very natural, because he had been here before.

When he first discovered the secret of the Book of Heaven, Yi Chen was sucked in here when he was taking a bath, and it was here that he saw the Book of Heaven rehearsing a complete pattern.

"It's strange how the Book of Heaven sucked me into this space again. There was confusion on Yi Chen's face, but his attention was quickly attracted by the space in front of him. There, there was a golden glow.

"What is that?" If Yi Chen remembered correctly, when he first came here, there was no such thing, and vigilance immediately appeared in his heart.

In order to find out, Yi Chen slowly stepped forward, approaching the golden light, and as he advanced, he could feel an inexplicable coercion.

"There is still a huge amount of soul power flowing around, could this be the soul power that Tianshu has absorbed into?" Sensing the surrounding situation, Yi Chen was very surprised, because the place where that soul power flowed was the place where the golden light was released.

"Could it be that thing, absorbing soul spirit stones?" His heart was full of curiosity, Yi Chen couldn't help but speed up his pace, and soon came to the golden light not far away.

At this time, he was finally able to see what was releasing the golden light, it was a round stone, which released an extremely strong suction force and absorbed all the soul power.

"Strange, how could there be such a thing in the Book of Heaven. ”

Yi Chen was very curious in his heart, observed carefully, and after making sure that there was no danger, he took a step to the side of the golden egg.

Tong Guò looked closely, Yi Chen found that this golden stone was covered with lines, and what was even more strange was that he felt that this stone, as if it was a part of himself, and after walking in, he could still sense its existence.

"What a strange feeling, is it also a part of the Book of Heaven?, or is it the core of the Book of Heaven?"

In an instant, Yi Chen's body trembled, his pupils dilated instantly, and at the same time, his hand quickly retracted as if he had been electrocuted, and quickly retreated several steps.

"There's a heartbeat in the stone, what the hell is that? Yi Chen's face was full of shock and horror.

At the moment when he put his hand on the stone just now, he could sense that there was a heartbeat in the stone, as if there was a creature inside, and this feeling made Yi Chen very shocked.

"Could it be that it's not a stone, but a magical beast egg that contains life?" Yi Chen instantly had such a conjecture.

"If it's really a monster egg, then how could it be in the Book of Heaven, and who sent it in. Countless thoughts appeared in Yi Chen's heart.

But he quickly vetoed it. Tianshu has been following him for more than ten years, if it is really a Demon Beast egg, I am afraid that it will start to hatch a long time ago, or it will be rotten, and it is impossible to keep it until now.

"If it's not a monster egg, then what would it be?" Yi Chen was even more puzzled, and he continued to observe the stone.

"There are a lot of complicated lines on it, is this a seal? Could it be that something is sealed in this stone?" Soon, a new idea came to Yi Chen's mind.

"It seems a bit unrealistic, if something is really sealed inside, how can it feel like flesh and blood with me. Yi Chen frowned.
