Li Yi took out the Xuanjin Mirror, opened the Mirror Demon Realm, and moved the more than 1,000 spirit crystals into it, and a large amount of spiritual energy was emitted, which immediately gave the Mirror Demon Realm a feeling of refreshment.

After a few hours, the aura in the Mirror Demon Realm was more than ten times thicker, although it was not enough to compare with the Demon Valley, but at least in a short period of time, those few Nine Treasures Trees would not wither and die.

Li Yi breathed a sigh of relief and continued to cut the spirit crystal, but he still felt that the speed was too slow, so he thought about it, so with the light of the spirit crystal, he urged the shadow demon supernatural power again, and the shadow under his feet suddenly dissolved, turning into five hundred palm-sized shadows, also having a head and torso, hands and feet.

"Move!" Li Yi thought to himself.

The five hundred shadows scattered in a swarm, knocking on the spirit crystal veins, breaking off one spirit crystal after another.

The speed suddenly increased dramatically.

Li Yi was still not satisfied, and urged the ant demon supernatural power that had just awakened, a large cloud of red mist gushed out from the palm of his hand, and thousands of fiery red flying ants flew in all directions, and the sharp fangs cut the spirit crystals like a bamboo, effortlessly, in less than half a day, Li Yi had 30,000 more spirit crystals in front of him.

Li Yi was secretly delighted.

As more and more spirit crystals moved into the Mirror Demon Realm, the aura of the Mirror Demon Realm became more and more intense, and when the number of spirit crystals reached 500,000, the aura in the Mirror Demon Realm had begun to approach the Demon Valley, almost the same.

Although there is a huge spiritual crystal vein under the Demon Valley, the aura of this spiritual crystal vein is not exclusive to the Demon Valley, it will almost be emitted to the entire Watch Island, and even a small part of the spiritual energy will overflow to the sea, while Li Yi's Mirror Demon Realm is a very small world, with an area of only tens of miles, and the aura will not overflow, so the natural concentration is high.

While the clones, shadows, fiery red flying ants, and Xiao Qi were cutting and carrying spirit crystals, Li Yi himself was not idle, but began to meditate and cultivate.

When Li Yi killed the ant demon before, he opened his demon pupil, which caused a lot of consumption of his divine soul, so he slowly cultivated it, so that his divine soul could recover as soon as possible.

He recalled what the ant demon had said before he died, and that expression, and the doubts in his heart surged again: "Why did the ant demon look so frightened when he saw the demon pupil?

But that seems unlikely.

Li Yi's demon pupil was discovered in the Seventh Human Realm, and when he first discovered it, there was even only a fragment of an eggshell, but he finally managed to gather a complete Heavenly Demon Egg, and it was only after many years of cultivation that it broke out of the shell, and it was impossible for the ant demon to see the demon pupil.

If it is said that the demon pupil once existed in the demon world, but later it was responsible for guarding the seventh human realm and became an egg, it also does not make sense, because that means that the ant demon had seen the demon pupil at least before the opening of the seventh human realm, and the seventh human realm has a history of hundreds of thousands of years, and the ant demon obviously does not have such a long lifespan.

"Could it be that in the demon world, there is still a demon pupil?" a ridiculous thought popped up in Li Yi's heart.

The reason why it is ridiculous is because the demon pupils belong to the heavenly demons, and the heavenly demons are all unique, the previous generation of heavenly demons will not die, and the next generation of heavenly demons will never be born, which means that it is impossible for two demon pupils to exist at the same time in the world.

"Unless ......" Li Yi suddenly had a flash of inspiration and thought of a certain possibility, but then shook his head and said with a wry smile: "No, no, that's too ridiculous!"

What he thought was that the two demon pupils looked exactly the same on the surface, but in fact there was an essential difference, that is, one was the left eye and the other was the right eye, so that they could coexist.

However, since there is a distinction between the left eye and the right eye, it means that these two eyes may have a more powerful body, a complete physical body. The demon pupil is only a small part of that body.

This is obviously a bit too absurd, and it is difficult for Li Yi to imagine that there will be such a powerful existence in the world.

He shook his head, put this ridiculous thought aside, and instead took out some Nine Treasures Leaf and began refining.

Before, he refined forty pieces of Nine Zhen Leaves at one time, and almost didn't kill himself, but after the scar was healed, he forgot the pain again, and still swallowed the forty pieces of Nine Zhen Leaves in one gulp, and the familiar sharp pain spread all over his body again, and Li Yi complained in his heart.

But no matter how painful it is, it must be endured when cultivating, especially when cultivating like Li Yi, who requires improving his strength in the shortest possible time, and he has opened up one hundred and eight dantians in his body, the foundation is too strong, and the price he needs to pay is naturally not comparable to ordinary people.

Forty Nine Treasures Leaf was finally refined and cleaned, and Li Yi's realm had a breakthrough, and from the late stage of the fourfold period, he stepped into the realm of perfection, and there was only one step away from the fifth level of the cave sky.

Impacting the big realm is different from the small realm, you need to increase the power of medicine and bombard it with fierce medicine in order to blast open the door of the realm as soon as possible, otherwise according to the cultivation method like a drop of water and a stone, I don't know how much time it will take.

Li Yi took out a hundred Nine Treasures Leaves, gritted his teeth, and swallowed them in one gulp.

Previously, after refining forty Nine Treasures Leaves at one time, Li Yi had already died of pain and came back to life, but now one hundred Nine Treasures Leaves, the spiritual power was dissolved, and it was two and a half times as violent, and Li Yi was naturally even more painful.

At this moment, what King Kong is not bad for supernatural powers, and what is intended to keep Qingming, is no longer effective, Li Yi's consciousness began to blur, as if the divine soul had withdrawn from his body and flew away to the nine clouds, standing on the high clouds, watching another person cultivate.

His flesh swelled rapidly, swelling into a ball of flesh, with bruised tendons bulging, his face purple, his eyes wide open, and he looked extremely hideous.

His body had reached a limit, and he was almost collapsing, and the slightest crack began to appear on his skin, making a sound as if it was about to break, and if anyone next to him heard it, he would probably feel creepy.

But Li Yi's body, after all, is still extremely tough, and it is not so easy to completely collapse, it is just maintained in a state of limit, and with the passage of time, the spiritual power of Jiuzhen Ye merges into Li Yi's meridians little by little, and after Zhou Tian's operation, it turns into true qi and sinks into the dantian.

The pressure on his physical body was relieved little by little, but the pressure on his dantian was getting bigger and bigger.

The dantian had to forcibly expand outward, until it was blocked by the gate of the realm, and it could no longer expand, and it was necessary to blast open the gate of the realm and step into the fivefold of the cave heaven in order to expand further.

So Li Yi gathered his true qi and launched an attack towards the gate of the realm.

There was a rumbling sound inside him, like thunder.

After bombarding it thousands of times, it finally exploded, and Li Yi's one hundred and eight dantian suddenly transformed together, becoming more vast and solid, and the quality of true qi was also greatly improved.

Five-fold Cave Heaven!

Li Yi stepped into a new realm in one fell swoop, and his body had a feeling of becoming more pure and condensed, and at the same time, his strength was more restrained and majestic.

What's more, it has taken a big step forward from the Cave Heaven Ninefold.

The reason why you have to step into the Cave Heaven Nine Folds first, and then you can cultivate the advanced chapter of the Thunder Emperor Jue and refine the realm, is that in order to integrate one hundred and eight dantians, you must first let all the dantians transform and expand to a certain extent.

Each dantian is like a small world in Li Yi's body, if the distance between these small worlds is too far, it will be too difficult to break through the barriers, so it is necessary to continuously improve the realm and reach the nine layers of the cave sky, so that the small world of the dantian will expand to a limit, and the difficulty of dantian fusion will be greatly reduced at that time.

In the next few days, Li Yi basically stayed in the depths of the ground, on the one hand, carrying spirit crystals, on the other hand, refining the Nine Treasures Leaves, after stepping into the Cave Heaven Fivefold, he refined another hundred Nine Treasures Leaves, consolidating the realm, and then continued to refine, and the realm was also rising.

Especially when he cultivated in the spirit crystal vein, he could swallow a large amount of pure spiritual energy with every breath, and his cultivation was even more like divine help, and his cultivation was almost visible to the naked eye.

When the thousand Nine Treasures Leaf was about to be refined, Li Yi's realm was also a matter of course, and he stepped into the fivefold peak of the Cave Heaven.

At the same time, the spirit crystals transported to the Mirror Demon Realm reached two million, and these two million spirit crystals were less than one-fifth compared to the entire spirit crystal vein.

The aura in the Mirror Demon Realm has become extremely rich, it has far surpassed the Demon Valley, under the nourishment of a large amount of aura, the bare Jiuzhen tree began to grow new shoots, which made Li Yi excited, although the new sprouts are still very small, but at this rate, it won't be long before he can harvest a lot of Jiuzhen leaves.

As for the Nine Treasures Fruit, it is not so easy to grow, and Li Yi does not have the luxury of expecting it.

When he excavated the spirit crystal, he did not dig blindly, but divided it into many directions and locations, and dug it evenly, instead of digging only one place all the time, so that the trees on the ground would quickly wither, so that the demon clan could see the clues.

"It will take some time for the new Jiuzhen leaves to grow. Li Yi secretly planned in his heart, "If I want to continue cultivating, I can only refine those three Nine Treasures Fruit." ”

Thinking of refining the Nine Treasures Fruit, Li Yi couldn't help but feel a little excited and nervous, not knowing what would happen after swallowing this legendary spirit fruit into his stomach.

Or there is another way, just like Lin Wei refining the Nine Treasures Leaf, soak the Nine Treasures Fruit in water, let the water absorb the spiritual power of the Nine Treasures Fruit, and then Li Yi can refine the water that absorbs the spiritual power of the Nine Treasures Fruit, which will naturally greatly reduce the risk, but the disadvantage is that it takes a lot of time.

Li Yi was thinking about it, when suddenly there were three knocks on the ground.

This was a sign that he had discussed with Gu Qiyue, indicating that someone was coming.

So Li Yi left Xiao Qi alone underground and continued to dig the spirit crystal vein, while he put away the shadow demon magic power and ant demon magic power and returned to the surface.

During this time, Gu Qiyue got another Xuanjin bed out of nowhere and covered the entrance of the cave. Li Yi climbed out of the bed, just as Gu Qiyue led a monster in.

"Lord Antdemon, we've caught a woman!"
