Before entering the cave, Li Changxin handed Li Chen a token, "This is the key to the ancient secret realm after opening the cave, which can protect you in the secret realm for half an hour, but remember to come out within half an hour, because the time cannot be completely determined, and accidents will inevitably occur." ”

For these words, Li Chen has his own guess, perhaps because the first gate has not fully mastered the secret realm behind the cave for so many years, there is so much uncertainty. At the same time, Li Changxin was confident that he would not be able to see all this place in half an hour, so he would give this time limit.

In half an hour, his doppelganger is actually enough to travel thousands of miles, so to be conservative, this secret realm in the cave is at least tens of thousands of miles.

After Li Chen really went in, he found that he was too small.

This is not only tens of thousands of miles, when Li Chen released his perception to the point that it became blurred, he still couldn't know the end of this place, the perception of his doppelganger was actually not much worse than the body, because the perception itself and the realm were different, and the incarnation outside the body that Hongxue gave him was really mysterious.

It can be said that his perception is not much worse than that of Li Changxin of the sect.

Soon, he came to the conclusion that this place was much larger than the territory of the First Gate.

However, the priority is not to explore the specific size of this realm, but to see if we can solve some of the mysteries of the life experience, or if we can obtain other complete ancient secret arts.

In half an hour, Li Chen first took out half a pillar of incense to walk through this territory, and when he encountered the bones, he took a closer look, and when he encountered the sinkhole left by the battle, he carefully felt whether he could get anything from it.

He looked at the mirrors frozen by blood at his feet, and when he walked over to take a closer look, he realized that it was originally a river, but because a drop of blood had mutated, it had become a tile-like condensation, crystal clear, and extremely hard.

He didn't know what kind of character's blood could reach such a point, at least his current body was far from it. When I first stepped into cultivation, I only felt that I was the strongest in the world but forgot about my worries, and now a drop of my own blood was enough to sink ten zhang square, but I felt that I was small.

He tried to do no damage to the river after trying his clone's supernatural powers, and immediately used his body to move forward.

Not long after, he saw another deep forest, and he felt a cold cold that penetrated deep into the bone marrow, and this coldness was weakened by the rune seal, but he still couldn't resist it, making his bones appear overwhelmed and crisp cracking in the extreme cold.

He hurriedly retreated, and it wasn't until hundreds of zhang later, after his body recovered, that he felt it carefully, and found that his body had just become more fragile in an instant, and he didn't know what kind of cold aura it was, it was so terrifying.

It's just that Li Chen looked at the depths of the bamboo forest, and there was a faint boiling and induction in his blood, which was an abnormality after he saw the remains of the golden crow last time.

Perhaps, entering it will lead to some kind of primeval mystery.

Li Chen was a little unwilling, "If I replace or even fuse the main body and the clone at this time, can I enter it?" ”

"Forget it, although the incarnation outside the body is mysterious, it can't be said to be omnipotent, in case you can't complete the shuttle between these two worlds, it will inevitably startle the snake."

Li Chen dispelled the idea of letting the body come here, and continued to shuttle through the secret realm with the body of the clone, in this space full of corpses and bones.

It wasn't until half an hour away that there were only ten breaths left of the book that he saw a stone tablet with a text on it.
