With a few plops, Li Yi and the others fell into a cave.

This cave is located in the middle of Changsheng Island, where Li Yi used to come before, and deliberately left a Xuanjin mirror in the cave.

When he left the Mirror Demon Realm and entered the cave, the Xuanjin Mirror immediately shattered.

The Mirror Demon Realm has completely collapsed, and all the entrances no longer exist, all of them have been destroyed.

The size of the Sword of Exterminating Immortals has shrunk a lot, and it has become like an ordinary long sword, and when the sword roars, it is about to fly out of the cave.

Li Yi hurriedly threw out the Sun and Moon Twin Swords, and imprisoned the Immortal Exterminating Sword again.

"Senior sister, it doesn't matter to you, right?" Li Yiqiang endured the severe pain all over his body, put Biying on a rock, and asked softly.

Bi Ying's face turned pale and shook her head slightly.

Li Yi looked at the others again, his face was also extremely pale, and it was obvious that the injury was not light. Although they escaped the danger for the time being, there was no joy on their faces, but they were full of sadness and anger.

Especially Lin Wei, she couldn't help but feel sad when she remembered that the Rock Demon had sacrificed her life to save her and was shattered by the Ninth Realm King, and her eyes were filled with tears, and she was silent.

Li Yi also remembered the tragic situation of Shi Niang being killed by the Ninth Realm King, his heart was full of anger, and he gritted his teeth and said, "One day, I will kill the Ninth Realm King!"

"Not bad. Tang Jing said, "The Mirror Demon Realm that we have worked so hard to manage has been destroyed by the King of the Ninth Realm, and the spirit crystals and spirit trees that we have finally found have also fallen into his pocket, and this revenge cannot be avenged!"

But at the moment, the most difficult thing is how to survive than revenge.

Without the protection of the Mirror Demon Realm, everyone can be said to be directly exposed to the Demon Clan, once they are discovered by the subordinates of the Ninth Realm King, it will not be so easy to escape.

Li Yi didn't have much of a problem escaping alone, but the strength of Biying and the others was not strong enough.

Li Yi forcibly lifted his true qi, made a hole in the ground, broke through the rock formation, and hit tens of thousands of zhang deep underground, opening up a small cave below.

"During this time, it is very dangerous outside, so let's recuperate here, and when the injury is healed, the outside limelight will pass, and then make plans. Li Yi said.

The crowd was silent, but no one objected.

Li Yi planted the supernatural power tree in a corner, sat cross-legged on his knees, and began to heal his injuries.

Li Yi didn't have time to take away the hundreds of spirit trees in the Mirror Demon Realm, as well as the hundreds of millions of spirit crystals, because the situation was too critical at the time, but this supernatural power tree could not fall under any circumstances, but fortunately, there was no danger in the end, and the supernatural power tree was finally saved.

For Li Yi, the Divine Power Tree is a powerful weapon to quickly improve his strength, allowing him to complete his cultivation of Divine Power as soon as possible, so as to transform it into a law.

Without the help of the Divine Power Tree, then if Li Yi wanted to control a law, he would need to pay a great price and spend a long time.

After all, Li Yi's body is strong, although he is not lightly injured, but after only two days, the injury has recovered to seventy-seven eighty-eight, on the other hand, Biying and the others still have not improved much.

"It's not a way to go on like this. Li Yi was very worried.

Now that the Mirror Demon Realm no longer exists, it is difficult for Li Yi to protect Biying and the others from the demon clan, after all, he is alone, and it is difficult to defeat four hands with two fists, especially in the melee, it is difficult to do everything.

If you want to protect Biying and the others, the only way is to help them improve their strength as soon as possible and refine the realm as soon as possible, when the time comes, they will not only have the power to protect themselves, but also become Li Yi's most powerful helper.

"I'm going to pass on a practice to you. Li Yi opened his mouth and said, "This exercise is the fundamental reason why I can live to this day, without this exercise, I'm afraid I would have died a long time ago." ”

Everyone looked up in amazement and looked at Li Yi together.

They had to be taught by Li Yi before, but they had not yet practiced it, and they didn't understand why Li Yi suddenly wanted to pass on another exercise, only Bi Ying realized what she wanted to say.

Li Yi said: "This technique is different from the Thunder Emperor Technique, it cannot be directly refined into the realm, but it is countless times stronger than the Thunder Emperor Technique. Its name is called Demon Refining Technique!"

"Demon refining technique?" Tang Jing and the others' faces changed slightly.

Li Yi said: "The demon refining technique is an ancient miracle skill that I accidentally obtained when I was in the seventh human realm, which can refine all the demons in the world and win their magical powers, and the reason why I was able to awaken the magical powers of the demon clan is this reason." In addition to gaining the demonic powers, this exercise can also strengthen your body by refining the essence blood of the demon clan, so that you can recover from your injuries faster. ”

When everyone heard this, they were moved.

Everyone can hear it, this demon refining technique is Li Yi's biggest secret. Cultivators, each of them has their own secrets, even between brothers, it is difficult to be completely calm. Not to mention that Li Yi has secrets, Tang Jing and others also have their own secrets in their hearts, and they will not easily confide in others.

Seeing that Li Yi actually confided his biggest secret, everyone was naturally moved, and they couldn't help but be a little moved in their hearts.

Li Yi had never revealed the secret of demon refining to anyone before, even Biying was no exception, but the battle of Shura City, the collapse of the Mirror Demon Realm, and the death of Yang Xiaohua gave Li Yi a great shock, making him feel an unprecedented sense of crisis, even fear.

In the past, he had absolute confidence in himself, but now he suddenly felt that he was weak, he was afraid of seeing another person die, he wanted to protect Biying and the others, and the best way was to let them also learn the magic trick.

The mental method of refining the demon recipe is not very complicated, but it is very obscure. After Li Yi taught the heart method, he explained to everyone the experience of practicing this exercise.

Everyone listened attentively and began to cultivate.

After a few hours, Li Yi stretched out his palm, and a drop of blood condensed above his palm.

This drop of blood is the natal essence blood of the demon clan.

In the battle of Shura City, Li Yi devoured hundreds of monsters, and a large amount of demon essence blood was accumulated in his body, which had not yet been refined.

"You guys try it and see if you can refine this drop of demon blood. Li Yi said.

Lin Wei's comprehension and cultivation are the highest, and she was the first to try, but after refining for a long time, she still couldn't refine that drop of demon blood, and she couldn't even suck the demon blood into her body.

"How can this be?" Lin Wei was frustrated, "I have obviously comprehended the Demon Refining Technique, why can't I urge it?"

Li Yi let others try again.

Who knows, but no one has successfully refined demon blood, it stands to reason that their understanding is not bad, and with Li Yi on the side, they did understand the essence of the demon refining technique in their hearts, but for some reason, the demon refining method is like a stubborn donkey, and they refuse to move no matter how they hurry.

In desperation, everyone had to give up.

Bi Ying said: "It seems that this exercise is not something that everyone can urge. I guess it may be like the Heavenly Dao Divine Power of the Demon Race, they are all unique, and if the Heavenly Demon can reproduce indefinitely, it will completely upset the balance, and it will be difficult for other living beings to survive. Similarly, this demon refining technique, if everyone can urge it, then it will be difficult for the demon clan to survive. ”

Li Yi nodded and said, "Maybe." Since you can't urge you to refine the Demon Technique, then you can only continue to cultivate the Thunder Emperor Technique and refine the realm as soon as possible, so that you can have a little self-protection power!"

Everyone's hearts were awe-inspiring, and since then, they have redoubled their efforts to cultivate.

It's just that after leaving the Mirror Demon Realm with abundant spiritual energy, without the assistance of a large number of spirit trees, the speed of everyone's cultivation is still relatively slow.

Li Yi is also working hard to cultivate.

His main energy was used to refine the demon essence blood in his body, and a large amount of demon essence blood accumulated in his body, if he hadn't forcibly suppressed it with the law of devouring, I am afraid that he would have gone berserk and died.

It took a few days to finally refine all the natal essence blood of those demon path monsters, Li Yi's true qi improved a lot, his physical body became stronger, and even his realm expanded.

But it still failed to break through the sixfold realm.

There are too many laws in the field, and there are such drawbacks, and it becomes extremely difficult to break through.

Li Yi was not discouraged, and continued to refine the natal essence blood of the Western Heavenly Venerable.

The natal essence blood of the Western Heavenly Venerable is extremely strong, and it is not so easy to refine.

It took half a month of refining before it was completely refined.

Li Yi's strength has improved a lot again, and both his true qi and his physical body have undergone a huge transformation, but there is still a gap between him and the sixth realm.

It took Li Yi a little time, awakened the Western Divine Power, and when he urged the Divine Power, the speed of traveling to the West became many times faster, and it was extremely fast.

So far, among the Quartet Divine Powers, Li Yi has already controlled three of them, only the Eastern Divine Powers.

Li Yi continued to refine Dongfang Tianzun's natal essence blood.

More than half a month passed, Li Yi finally refined all the natal essence blood of Dongfang Tianzun, his body shook suddenly, and a majestic aura shook out, causing the cave to tremble endlessly, and a lot of rubble fell.

That majestic aura shook back all the Biying and others around Li Yi, and pushed them away from afar, all of them were shocked, not knowing what was going on.

After a long while, Li Yifang opened his eyes and exhaled slowly.

That majestic aura immediately retracted into Li Yi's body.

Realm Sixfold!

After refining Dongfang Tianzun's natal essence blood, Li Yi's realm finally broke through and stepped into the realm of the sixth level, and his realm expanded rapidly, reaching three thousand zhang in one fell swoop.

A breakthrough has increased by nearly 1,000 zhang, which is rare in the world.

The vast majority of the Demon Clan Heavenly Venerables, when they were in the realm of the sixfold realm, the realm was only more than a thousand zhang, and some did not even have a thousand zhang, but Li Yi reached three thousand zhang, which was far from being comparable to those Demon Clan Heavenly Venerables.

Li Yi was secretly relieved, Bi Ying and the others also felt refreshed when they saw his strength improve, and the morale that had been low due to the battle of Shura City had also improved.

At the same time, Biying and others also felt a kind of pressure.

There was already a big gap between them and Li Yi's strength, and now the gap has not only not narrowed, but has expanded, as if they are whipping them, and they have to work harder.
