Lu Yi came to a stone tablet on the edge of the square, and saw a passage written in two words: human and demon. The content of this passage is an overview of the 124 secret realms of the Heavenly Pass, and emphasized that these four stone platforms are called the fourth level of heaven. If you want to reach the top to complete the challenge, you must pass through the 72-stage ladder of each stone platform. There are various unpredictable situations on the ladder, which can be said to be full of difficulties and dangers. Once you step on the ladder, you will not turn back. If you think you are not strong enough, don’t challenge it rashly. You can choose to go to the teleportation array in the center of the square to leave the secret realm.

These situations are the same as Lu Yi knew before. The cultivators who entered the secret realm of the alliance were all the best spirit-controlling elites. Especially when they learned that the reward of the last level could actually complete the spirit-building, it made the spirit-controlling cultivators even more crazy. Many people were able to get here through the twenty-level challenges, but there was no one who really had the courage and strength to complete the four levels of challenge so far, and at most one person had passed two levels of heaven.

Lu Yi waited here for a long time, trying to see if there were other people who completed the previous challenge and walked here. But he didn't know if he was too fast or too slow. He waited for a long time without waiting for the latecomer. Lu Yi didn't want to do so and dared not waste time anymore. He got up and walked towards the first heaven marked by the stone tablet. According to the records of the stone tablet, the fourth heaven should be challenged in turn.

Lu Yi came to the first level of the world and looked up at the towering stone platform. The person seemed so small under it. At the bottom, it was the first floor of the ladder of the sky, which was ten feet high and nearly ten feet wide. As long as you fly up to it, the challenge will begin.

According to those who have successfully passed the level before, the ladder of the fourth level is unpredictable and dangerous. After climbing to the ladder, they can only move forward step by step. The previous step may still be calm, and the next step may be to face infinite murderous intent. Moreover, these dangers are diverse, covering any means currently visible to the mainland.

Lu Yi circled around Yi Chongtian, looking for the direction to start with intuition. After a while, he had no inspiration. After a while, he turned around again, but still no flash of inspiration appeared.

Lu Yi stood there in a daze. Suddenly, his mind moved and he looked in the direction of the second heaven. Lu Yi was wondering, if there was a mysterious existence in this secret realm, could he not follow the rules? He jumped and leaned quickly towards the second heaven, then turned around the second heaven for a few times before reaching the third heaven.

Lu Yi also circled around the third heaven for a few times and walked straight to the fourth heaven. He looked up and did not do any more movements for a long time, as if he wanted to see through the fourth heaven.

For some reason, Lu Yi always felt that there seemed to be a pair of eyes staring at him on the top of the four-level sky that was high, as if the unknown existence was hiding here.

After staring for a long time, Lu Yi suddenly made an unexpected move. Lu Yi jumped onto the ladder of the fourth heaven! No accident happened, the first ladder of the fourth heaven was actually very quiet and safe!

Lu Yi stayed for a moment, took a step forward, and was safe; another step, and was still safe; step by step, Lu Yi walked to the edge of the second floor of the ladder, jumped up, and went up!

Second floor, third floor, fourth floor

Seventy-fourth, seventy-one, seventy-two!

Lu Yi came to the top of the fourth heaven like a leisurely stroll in the courtyard. A hall appeared in front of him, and the entire hall was magnificent.

The hall gate was closed. Lu Yi came to the entrance of the hall and raised his hand to push the hall gate, but found that the hall gate was as heavy as a huge rock. Lu Yi used all his strength but still couldn't push it open.

"Come out! I know you're inside!" Lu Yi tried to enter the door but failed and shouted at the hall.

No sound, no response.

"Okay, you won't come out, right? Then I won't leave." Lu Yi sat down cross-legged.

The confrontation continued. I don’t know how long it took, but a thin crack was opened with a "creak" sound, but nothing appeared.

The existence inside could not come out, and Lu Yi didn't dare to go in. Who knows if it was malicious and would set up some ambush inside? After confronting each other for a long time, a nasty voice finally came from inside, "Come in!"

Lu Yi could conclude that this was the voice of a human race, but this person seemed to be a little unscrupulous. He said he was stuttering, not stuttering. Anyway, it sounded very hard to pinch.

"Who are you and why are you here?" Lu Yi still didn't dare to take a step easily, and he continued to ask.

"I, I, I, have been talking for thousands of years, no, no, I have spoken." The voice came again, and Lu Yi finally figured out why it was so awkward to listen to this person's speech.

"Come in! I, no, will harm you!" The voice sounded again, his tone was very sincere.
