Immortal cultivation starts with copying.

The moment the door closed, an invisible restriction appeared out of nowhere.

Although everything happened suddenly, neither Chen Yunhao nor Zhao Yuyang's expressions changed.

People like them have been practicing for thousands or even tens of thousands of years. They have long since cultivated to the point where they are not surprised by anything. They are very shrewd and will not panic because of such a small thing.

However, their vigilance was raised in an instant.

Before the two could make any move, the entire building seemed to spin, giving people a dizzy feeling.

Next, the two of them seemed to be teleported away, the scene in front of them suddenly changed, and they could no longer see each other.

The scene Chen Yunhao saw before his eyes was a mountain that towered into the clouds.

There is a flat area of ​​about a thousand feet on the top of the mountain. Complex array patterns are engraved on the ground, covering the entire ground. It is obvious that this is a large array formation.

In the center of the formation stood a thin middle-aged cultivator. He seemed to have no cultivation at all, just like an ordinary person, but he gave people a feeling of being an immortal.

Chen Yunhao was standing in the distance like a bystander at this moment, and could see the monk's every move and the expression on his face.

The monk had been looking up at the sky, but now he seemed to be able to see Chen Yunhao and looked in his direction.

But he just glanced at it and ignored it.

But Chen Yunhao felt as if the monk nodded slightly at him, as if it was an illusion.

Chen Yunhao was shocked. He didn't know whether he was in a fantasy or in reality.

But he clearly felt that what he saw was an illusion and not real at all.

But if it was an illusion, how could there be any intersection with the characters in the illusion?

Could it be that this illusion has something in common with the ancient mirror space?

Chen Yunhao looked up following the monk's gaze, and saw that the sky was already covered with dark clouds.

Those dark clouds were not ordinary dark clouds seen in the mortal world. They were as black as ink, as thick as mountains, and thousands of feet high. It seemed that the entire world was filled with these dark clouds.

“Surviving the Immortal Tribulation…!”

Chen Yunhao cried out softly. He had survived many heavenly tribulations and had seen others survive tribulations, but he had never seen such a massive and devastating heavenly tribulation like the one before him.

A heavenly tribulation of this magnitude can only occur when one is going through the tribulation of immortality. At this moment, Chen Yunhao did have a clue in his mind.

There is something to be gained in this secret place. The real gain is here.

What an opportunity it is to watch others transcend the immortal tribulation. Even the famous tribulation-transcending cultivators in the spiritual world may never see it in their entire life.

Chen Yunhao held his breath and stared intently.

At this moment, he felt that he was too close and wanted to step back a little, but his body seemed to be nailed down and he couldn't move.

The pressure on his body became stronger and stronger, as if the whole sky was about to collapse.

The thin middle-aged monk had his hands behind his back, his face still calm, not affected at all.

As a pure bystander, Chen Yunhao could indirectly sense the pressure brought to him by the immortal tribulation, and he felt it was difficult to breathe.

The strange phenomena in heaven and earth had been brewing for three days, and finally the first immortal thunder fell from the sky.

This is the real immortal thunder, which has crossed the barriers of time and space and comes from the immortal world.

The fairy thunder is purple, not very bright, and it is very thin, like a rope.

But this inconspicuous immortal thunder contains the power to destroy the world.

Even though Chen Yunhao has reached the Mahayana stage of cultivation now, he feels that he cannot even withstand this first immortal thunder and will definitely be reduced to ashes.

But the thin monk just waved his hand casually, as if to drive away an annoying fly, and the first fairy thunder disappeared out of thin air with a wave of his hand.

Chen Yunhao was watching from the side, but he saw it clearly. When the cultivator waved his hand, a black light appeared and directly destroyed the first immortal thunder.

Chen Yunhao felt that the black light was somewhat similar to his own magnetic divine light, and might be the same kind of magical power.

The thin monk used the same method to block three immortal thunders in a row.

Some say there are eighty-one thunders in the process of transcending the immortal tribulation, while others say there are eighty-two.

There are different opinions on the exact number, but most of the records in ancient books are eighty-one.

Taking advantage of this opportunity, Chen Yunhao can actually see how many there are.

When the fourth immortal thunder began, the cultivator used spiritual treasures, each of which was a top-grade spiritual treasure.

But even if it is a top-grade spiritual treasure, it is only disposable and can only withstand one immortal thunder.

No matter what kind of natural disaster it is, the power of the thunder will become stronger as time goes by.

The thin cultivator had consumed five or six top-grade spiritual treasures. It was not because he had no more in stock, but because even the best spiritual treasures could not withstand a blast of immortal thunder.

So, he took out another treasure, which was a broken sword with a broken tip.

However, the aura emanating from this broken sword was extremely terrifying. The moment it was taken out, it seemed as if the space was distorted.

“Semi-Immortal Weapon…!”

Chen Yunhao's eyes narrowed and he almost cried out in surprise again.

Although Chen Yunhao had never seen an immortal weapon, or even a semi-immortal weapon.

However, the aura emitted by the semi-immortal weapon in front of him was obviously almost the same as the immortal energy in his body.

There is no doubt about this. A cultivator who is undergoing tribulation and does not have immortal energy in his body cannot drive a real immortal weapon.

Only this kind of semi-immortal weapon can be used by monks who are undergoing tribulation.

Even though that cultivator had the top-level cultivation to transcend tribulation, it was not easy for him to drive a semi-immortal weapon. Every time he swung it, it would consume nearly 10% of his spiritual power.

The broken sword could only withstand five or six immortal thunders before it had to stop. If it continued to be consumed, the spiritual power in the body would be less than half.

But the fairy thunder in the sky has only traveled 30% of its way, and it is still a long way from the 9981 steps.

Chen Yunhao was not optimistic. He had already used up the semi-immortal weapon. What other means could he use to withstand most of the immortal thunder?

The thin monk did not put away the broken sword of the semi-immortal weapon in his hand, but threw it casually, and it sank directly into the distant cliff and disappeared without a trace.

When Chen Yunhao saw this scene, he was thoughtful, but he had no time to think too much because the new fairy thunder had already fallen.

The thin monk stomped his feet, and the formation under his feet began to glow. In the blink of an eye, a ninth-level spiritual formation appeared.

It is not uncommon to use formations to resist immortal thunder. Many formation practitioners use this method to resist, and it can be regarded as one of the ways to overcome tribulation.

However, the formation in front of him was quite large in scale, and at first Chen Yunhao felt that it should be a ninth-level spiritual formation.

However, the ninth-level spiritual formation is also unable to withstand the immortal thunder, which is the consensus of everyone in the immortal cultivation world.

The cultivator who is undergoing tribulation in front of him cannot possibly be unaware of this, so this formation must be very complex.

Sure enough, after the formation was activated, Chen Yunhao was shocked.

This is not an ordinary ninth-level spiritual formation. It should be an immortal formation passed down from the upper realm. Its power has long surpassed the ninth level.
