Wu Lai didn't care about them, and went directly to the depths of the polar region. He has already done what he should have done for the sake of the bones and the earth, and it is up to them to develop in the future. To be honest, Wu Lai's enslavement of the Bone Shock and Bone Movement and letting them form a skeleton army is just a play, and the most important thing is actually to improve his own strength. He himself knows this very well.

The deeper you go, the greater the gravity, but it's nothing to Wu Lai. Soon, he came across a crystal skeleton. The Crystal Skeleton is much more powerful than the Purple Gold Skeleton, and it can be said that it is the most powerful existence among the Purple Gold Skeletons, and it has begun to transform into a Crystal Skeleton, but in the face of the real Crystal Skeleton, it is at most a battle power, but it cannot really compete. After all, the strength of the crystal skeleton is comparable to that of the Immortal Emperor, and the worst crystal immortal emperor is the strength of the early stage of the Immortal Emperor, not comparable to the purple gold skeleton, and these skeletons are not invincible at the same level like Wu Lai, and they can leapfrog the challenge like Wu Lai.

This crystal skeleton suddenly came out of the ground, and the movement was not big, and after seeing Wu Lai, he waved the bone knife in his hand and slashed at Wu Lai. That knife, unpretentious and unpretentious, without any fancy points, just slashed straight over, but it was enough to cut through the void and cut off eternity. Although the strength of this crystal skeleton is only the bottom of the crystal skeleton, its strength cannot be underestimated, and the ordinary Immortal Emperor is not his opponent at all in the early stage.

It's a pity that it encountered Wu Lai, and it was doomed to tragedy.

"Haha, it's good to come, my son is looking for you. Wu Lai was not afraid of the knife that cut off the void, and directly punched over, and the powerful fist burst out, breaking the knife, and at the same time, Yu Wei blasted the crystal skeleton far away, and the body was torn apart and scattered all over the ground, especially the skull, which flew far away, fell to the ground, and rolled far away before stopping.

The soul fire in the skull of that crystal skeleton was much brighter than the soul fire of the skeleton that Wu Lai had seen before, flickering, and his spirit fluctuated violently. The skull suddenly rolled on its own, as if summoning, and soon the skull was connected to the cervical vertebrae, then to the right arm and right hand, and then the right hand assembled the torn body, and finally stood up, holding a bone knife, and struck Wu Lai again. In this polar environment, the skeleton of the crystal skeleton is extremely hard and difficult to break, except that the joint joints are broken. After the bones of the whole body are reassembled, it seems that there is no immobility, and there is no immobility, and it can almost be called immortal. Moreover, skeletons are almost immune to all kinds of spells, and are almost invincible at the same level.

Wu Laishi exhibited the Eight Desolations Liuhe Fist, which opened and closed, shook the sky and shook the earth, and the fist was full of heaven. However, under the influence of strong gravity, the power was reduced by three points.

Previously, Wu Lai didn't notice this, because he didn't go so deep, and he didn't use the Eight Desolation Liuhe Fist, but now he found that the power of the fist method had been weakened by three points. Not only that, but even the Divine Passage Law was suppressed.

The Eight Desolation Liuhe Fist could only suppress the Crystal Skeleton's attack.

However, Wu Lai became more and more smooth, his fist intent was extremely domineering, and the crystal skeleton was still wise, and when he saw it, he was defeated, he fled, and wanted to burrow into the ground, but he was blown up by Wu Lai's punch, including the bone knife in his hand. Today's Wu Lai, the early stage of the Immortal Emperor is no longer his opponent, and even in the middle of the Immortal Emperor, he may not be able to defeat him. Therefore, it was not difficult for him to kill this crystal skeleton.

The soul fire of the crystal skeleton flew towards Wu Lai. The soul fire of the crystal skeleton is a great supplement to Wu Lai's primordial spirit, and his primordial spirit is not a little bit stronger, although the realm is still the early stage of the Immortal Monarch, but it is already comparable to the middle stage of the Immortal Emperor.

Now, he is no longer lost.

Continuing to march into the depths, the strength of the crystal skeleton was stronger, and it was killed by Wu Lai several times along the way, and it gained a lot.

Wu Lai found that although the power of the Divine Passage Method, the Fist Technique, etc., was weakened, the effect of cultivating in this environment was much better than cultivating in other environments. He also found that every time he went deep into 10,000 miles, the gravity doubled, and the place where the Nameless Immortal Emperor crossed the tribulation was the range of gravity that the average Immortal Emperor could withstand in the early stage, and now Wu Lai had gone deep into a million miles, and the gravity was a hundred times that of before. A hundred times the gravity, the average Immortal Emperor couldn't bear it at all in the early stage.

While Wu Lai went deeper, he sank down to cultivate and sharpen his body. Along the way, every time gravity doubled, Wu Lai practiced all of what he had learned, including the Wuji Nine Styles, the Wuji Three Slashes, the Eight Desolation Liuhe Fists, the Wuji Divine Fists, the Six Paths of Reincarnation Fists, the Creation Divine Palms, the Immortal Divine Method, the Dominating Sacred Laws, the Heavenly Emperor Fist, the Supreme Divine Fist, the Immortal King Fist, the Ling Tian Divine Fist, the Ling Tian Hammer, the Wordless Law Seal, the Ling Tian Nine Swords, the Nine Martial Arts Styles and other unique learnings. If you don't practice it often, you will become rusty. Now that he had practiced it a hundred times, his understanding of these peerless techniques had become even more profound, which made his Ling Tian Divine Fist even more powerful. In fact, he had been brewing the fourth punch of Ling Tianshen Fist, but he had no inspiration or clue. It takes chance.

In addition, Wu Lai has a lot of questions in his heart. Why are there creatures like skeletons in the polar regions? How can skeletons still be alive? Are they a race? What kind of life forms are they? How is their soul fire formed? Why can they strengthen the primordial spirit of immortals? Can skeletons still recover their physical bodies? Wu Lai had also asked the Nameless Immortal Emperor before, and he had asked Sharp, but he couldn't say why.

Wu Lai continued to go deeper, in fact, he also wanted to find the answer. He was really, really curious.

Going deeper, Wu Lai encountered an even more powerful crystal skeleton, whose strength was comparable to that of the middle stage of the Immortal Emperor. And the gravity here is more than 1,000 times that of before.

At that time, Wu Lai was practicing the Nine Styles of Martial Arts. Unexpectedly, this skeleton drilled out directly from the ground behind Wu Lai and quietly killed Wu Lai. This is a sneak attack.

However, Wu Lai watched the six directions with his eyes and listened to all directions, and his divine thoughts never relaxed his vigilance.

"It's a good time!" Wu Lai dodged the attack of this skeleton and used Ling Tian's martial arts to fight it. The skeleton's bone rod danced, opening and closing, collapsing the void, and Wu Lai's martial arts nine forms were even more powerful, and they were no longer suppressed by the gravity environment, which was extremely domineering.

This skeleton was broken up by Wu Lai several times, and they were all reassembled, as if they couldn't beat Xiao Qiang. Although the skeleton was weaker than Wu Lai, it was extremely difficult for Wu Lai to kill it, as its bones were so strong, and it also had a bone shield that neutralized most of Wu Lai's damage to it.

After being broken up for the last time, it was assembled, and the skeleton's soul fire fluctuated violently. Soon after, another crystal skeleton emerged from the ground, and its strength was similar to that of the skeleton just now.
