Lu Yi came to a stone tablet on the edge of the square, only to see that a passage was engraved on it in two languages, human and demon, the content of this passage is an overview of the one hundred and twenty-four secret realms of this Tianguan, and emphasized that these four stone platforms are called the four heavens, and if you want to climb to the top and complete the challenge, you must go through the seventy-two steps of the ladder of each stone platform. There are all kinds of unpredictable situations on the ladder, which can be described as difficult and dangerous, and once you step on the ladder, there is no turning back, if you think that your strength is not enough, you can choose to go to the center of the square and leave the secret realm from the teleportation array there.

These situations are also the same as what Lu Yi knew before, the monks who entered the secret realm of the alliance are all elites of the Imperial Spirit Period who have been selected by the top, especially when they learned that the reward of the last level can actually complete the spirit building, it makes those Imperial Spirit Monks even more crazy, many people have been able to pass the challenge of twenty levels to get here, but there is no one who really has the courage and strength to complete the challenge of the four levels so far, and at most one person has only passed the two heavens.

Lu Yi waited here for a long time, wanting to see if there were other people who had completed the previous challenge and made it here, but he didn't know if he was too fast or too slow to break through the level, and he didn't wait for the latecomer for a long time. Lu Yi didn't want to and didn't dare to waste any more time, he got up and walked towards the first day marked on the stone tablet, according to the stone tablet, the four heavens had to be challenged in turn.

Lu Yi came to the first world, looked up at the towering stone platform, and people looked so small under it. At the bottom, there is the first floor of the ladder of a heavy sky, which is one zhang high and nearly ten zhang wide, as long as you fly to it, then the challenge will begin.

According to the people who have successfully broken through the level before, the ladder of the four heavens can be described as unpredictable and dangerous, and after going up to the ladder, you can only move forward step by step, the first step may still be calm, and the next step may be to face infinite killing. And these dangers are varied, covering any means currently visible on the continent.

Lu Yi circled around a heavy sky, looking for which direction to start with his intuition, and after a circle, he didn't have the slightest inspiration, and after stopping for a while, he turned around again, and there was still no flash of inspiration.

Lu Yi stood there in a daze, suddenly, his mind moved, looking in the direction of the second heaven, Lu Yi was thinking, if this secret realm has that mysterious existence presiding, can he come without following the rules? He jumped forward, quickly leaned towards the second heaven, and then circled around the second heaven a few times and then came to the position of the third heaven.

After Lu Yi circled around the Triple Heaven a few times, he walked straight to the Quadret Heaven, he looked up, and didn't make any more movements for a long time, as if he wanted to see through the Quadruple Heaven.

I don't know why, Lu Yi always felt that there seemed to be a pair of eyes staring at him on the top of the four heavens high above, as if the unknown existence was hiding here.

After staring for a long time, Lu Yi suddenly made an unexpected move, Lu Yi actually jumped onto the ladder of the four heavens! There was no accident, the first layer of the ladder of the four heavens was very quiet and safe!

Lu Yi paused for a moment, raised his feet and took a step, safe and sound; another step, still safe and sound; step by step, Lu Yi walked to the edge of the second floor of the ladder, jumped up!

2nd floor, 3rd floor, 4th floor...

Seventy floors, seventy-one floors, seventy-two floors!

Lu Yi came to the top of the Four Heavens like a leisurely stroll, and a large hall appeared in front of him, and the entire hall was splendid.

The door of the hall was closed, Lu Yi came to the door of the main hall, raised his hand to push the door of the hall, but found that the door of the hall was as heavy as a boulder, and 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 without success, and shouted into the hall.

No sound, no response.

"Okay, if you don't come out, then I won't leave. Lu Yi sat down cross-legged.

The confrontation continued, and I don't know how long it took, and the temple door creaked open, but nothing appeared.

The existence inside can't come out, and Lu Yi doesn't dare to go in, who knows if it has malicious intentions, and whether it will set up some ambush inside? After confronting each other for a long time, a jerky voice finally came from inside, "You, come in!"

Lu Yi can conclude that this is the voice of the human race, but this person seems to be a little uneasy to speak, saying that it is a stammer, but not a stammer, anyway, it sounds very unpleasant.

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

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

"You, come in! I, no, I'm going to hurt you!" the voice sounded again, and the tone was very sincere.

Lu Yi got up, was on guard, and slowly walked towards the hall step by step.
