In the Black Stone Plain, Liu Li gave such a name to the world he is currently in. The name can be said to be extremely apt - there is nothing to be seen here except the black rocks everywhere, there are no mountains and rivers, no vegetation and jungles, no insects, fish, birds and beasts, and there is no trace of civilization. Liu Li, who was holding a giant shield, was still very vigilant about the environment here at first, for fear that he would encounter a surprise attack like the upper layer. It's just that now, he has been exploring here for three days with a cautious attitude, not to mention that the "cornerstone" incarnation has not been seen, and even the surrounding environment has not changed much.

In the past three days, Liu Li has not wandered aimlessly, at least he has done some simple investigations on the characteristics of this "cornerstone" world, and what he cares about the most is that this layer of world is extremely solid.

This degree of solidity is not a joke - Liu Li just looks at the strength, compared with the owner of the Golden Giant bloodline before the minor, and now that he has experienced a life rank promotion and five years of cultivation, even if Lin has adapted to the changes in strength after adulthood, he is only slightly better than him in the pure strength competition. And the giant shield "cornerstone" in his hand, among his own four elemental crystallization weapons, is also ranked first in terms of solidity. He had tried to burst with all his might, slashing the ground with the sharp edge of the giant shield, but the end result was only a scratch no more than a centimeter deep.

"What is this test?" At this time, Liu Li only had this one question in his mind, as a spellcaster, he was not short of patience, but he also knew that it was not a way to go on like this.

"What should be built on top of the 'cornerstone'? What should be the foundation? What makes the world that this 'cornerstone' of the heart and martial arts is so strong?" Whether it is the initial "return" or the "hostility" he has just experienced, the test is not to ask him how strong his combat effectiveness is, but to test his understanding of Xinwu.

In the face of the embodiment of "hostility", his practice of handing everything over to instinct is opportunistic, but it is also crooked, but in the face of the "cornerstone" at this time, he knows that these questions can only be answered by himself.

The giant shield "cornerstone" was placed in front of his lap, Liu Li closed his eyes tightly, and sat quietly on the hard earth of the Black Stone Plain, he had forgotten the passage of time, but he did not stop thinking for a moment. Gradually, Liu Li's figure was covered by the black stones, as if to completely merge with the surrounding black stones and turn into a part of the plain.

"On top of the 'cornerstone'...... Carry all things!" Suddenly, Liu Li opened his eyes and said the answer to the first question in a hoarse voice. As the words came out, the entire world of the Black Rock Plains shook, and the breeze blowing from nowhere brought a touch of life to this silent world. Immediately afterwards, there is a scene of the revival of all things, the warm sun rises into the sky, the blue sky is like washing, and everything grows on the black earth, and it is thriving.

"I ...... It's the cornerstone!" moved his stiff body, Liu Li stood up and gave the answer to the second question, his voice was no longer hoarse, and his eyes were blazing. Thin clouds appeared in the sky, and a light rain sprinkled on the earth, nourishing all things while turning into rivers and lakes, bringing more life to the world. In an instant, the clouds and rain dispersed, and a rainbow pierced the sky.

"My will...... This is the reason why this solid world was born!" One step, although Liu Li still stands on the earth, it seems that the whole person is on top of the world, his voice is clear and loud, swearing the sovereignty of this world. Picking up the "cornerstone" of the giant shield and carrying it behind him, Liu Li breathed a sigh of relief, and the whole person dissipated between heaven and earth, turning into a little green streamer and melting into the earth under his feet.

......

"After the 'cornerstone', it should be 'condensation'...... What kind of world will it be this time?" Before the thought was finished in his mind, Liu Li found that he was already in a clear body of water, and the giant shield "cornerstone" that he was originally holding in his hand was naturally replaced by a long-handled battle axe representing "condensation".

Liu Li could feel the pressure and resistance in the water, but surprisingly, her breathing was not affected in any way. He didn't know how wide this water area was, but waiting for more than ten minutes before sinking to the bottom was enough to prove its depth, and you must know that the weight of the tomahawk "condensation" in his hand was nearly a ton, and the sinking speed was not slow.

The water is not calm, and it is not easy for Liu Li to stay in shape in this body of water full of undercurrents and whirlpools. Just as he had just adapted to the environment he was in, a pale blue shadow came behind him at some point, and the battle axe in his hand, which was the same as "Shen Ning", was slashing straight down his back.

Liu Li's reaction was not unpleasant, but the resistance in the water affected his movements, although he successfully blocked the slash with the handle of the axe, but his body was in a mess and could no longer care about the ubiquitous undercurrent around him, and he was caught in it, and he was dizzy for a while. At the same time, he keenly noticed that the opponent's battle axe slash left a rapidly spreading ice flower on the handle of the "condensed" axe, and his heart couldn't help but sink again.

This layer of the underwater world is the same as the three-layer Xinwu world experienced before, and there are no elements. It is precisely because of this that the blue shadow is just a blow that urges Xinwu, and it actually plays an effect that only magic can do, which makes Liu Li's heart even more shocked.

"How did you do it, and is the 'condensation' of 'condensation' really just condensation?" Liu Li, who was in thought, did not let down his vigilance, and the mysterious blue shadow did not seem to intend to hide his figure again after a sneak attack, and forced forward again with a battle axe in his hand. Liu Li, who had restabilized his body, saw the other party's reaction, and no longer did that meaningless thinking, "Since you can't figure it out, let's get a result!"

Weapons clashed again and again, and there was a sound that was not dense, but extremely dull. Liu Li could feel the cold that penetrated deep into his bone marrow, but his strong physique was enough to ensure that the movements of his hands would not be affected by half a point.

As the battle continued, Liu Li's heart became calmer, as if watching his battle with the blue shadow from the perspective of a detached outsider. As the sense of detachment deepened, I don't know when his attack also brought the same chill as the other party. Finally, after a heavy split, the dark blue shadow was sealed into the solid ice with a blow, and then shattered into powder, and Liu Li was just right to stand at the bottom of the deep water.

"It's finally going to be the end, but I don't know what the core of this heart martial arts is......" Liu Li, who muttered to himself, only felt a flower in front of him, and when he came back to his senses, he was already floating in the empty void.
