Actually, it wasn't that the invisibility technique had lost its effect, but that the black-clothed person was too shrewd. With just the sound of a branch breaking, he could have made a move.

It was a good thing that Dong Wen Feng had always been cautious and prepared for his opponent. When the black clothed man attacked, he had already made preparations for defense.

Although he was in a rush, Dong Wen Feng's Innate True Origin was able to block thirty to forty percent of the attacks. The other attacks were strong, but they were not fatal.

Dong Wen Feng did not even think of fighting with his opponent, and immediately revealed his body, his body technique and Flash Technique, preparing to escape.

However, the black clothed man seemed to be able to see through Dong Wen Feng's body, and directly rushed towards his own body, causing Dong Wen Feng to immediately recall his body to block the attack.

This person with 80% of Dong Wen Feng's strength, in the hands of the black clothed man, did not even take three moves, and directly transformed back into spirit qi which floated in the air.

"Damn, why did he provoke such an old monster?"

Dong Wen Feng cursed as he ran. Sensing the overflowing killing intent behind him, Dong Wen Feng was even faster.

The black clothed man's speed was not slow, it was even faster than Dong Wen Feng. The other party seemed to be teasing him, and did not increase his speed to the maximum, but had always been taking revenge on him at a distance of ten meters, allowing Dong Wen Feng to maintain this feeling of urgency.

Dong Wen Feng thought that the other party did not plan to kill him directly, so he did not waste any more True Essence.

The black clothed man did not notice that Dong Wen Feng was abnormal, and thought that Dong Wen Feng had no choice but to slow down because he did not have enough True Essence.

Dong Wen Feng's brain started to churn, trying to think of a way to get rid of the black-clothed man's tracking.

The cultivation level of the black clothed man was unknown, it was at least one whole realm higher than Dong Wen Feng, which meant that he was at least an early stage Innate.

Cultivators at this level were not things that Dong Wen Feng could understand, and he was also unsure of what methods cultivators at this level had.

But when he thought about the Sky Dragon Secret Realm, he knew that there were definitely beasts of the Innate Realm here. Dong Wen Feng could only hope to use the beasts here to get rid of the man in black.

To the demon beasts, the black clothed man was like a threatening flood of ferocious beasts. When those Heaven level demon beasts sensed the aura of the black clothed man, they had already run far away.

"Senior, who are you? Why are you targeting me?" Dong Wen Feng asked tentatively, knowing the situation the other party was in so he could come up with a strategy.

"Don't try to trick me, don't run away. You won't be able to escape from me today." The voice of the black clothed man was as bone-piercing as ice. His killing intent was like a fishnet that wrapped Dong Wen Feng up.

Hearing her say that, Dong Wen Feng felt extremely depressed in his heart. No one could understand why he had offended her.

He hated the dragon group to the core. They actually let in such an old monster. Who could contend against them?

Sky Dragon Secret Realm was a secret realm that the dragon group had specially opened to train the younger generation of disciples. Cultivators who had reached the innate realm and above should not be able to enter.

While the two of them were in pursuit and escaping, they quickly reached the center of the Sky Dragon Secret Realm. Dong Wen Feng's true essence was almost exhausted.

Suddenly, he saw a pond not far away. Dong Wen Feng had an idea and jumped into the pond.

The black clothed man followed closely behind and entered the pond at the same time. The pond seemed to have a mysterious power that sealed off one's spirit sense, and the visibility of the pond was very low. Dong Wen Feng disappeared from the sight of the black clothed man.

The black clothed man was so angry that he struck the water, causing ripples on the surface, while Dong Wen Feng was like a nimble fish swimming in the water.

Gradually, Dong Wen Feng started to feel the cold. It had to be said that Dong Wen Feng had specially trained his flesh before, even if he was in the extreme regions of the world, he would not feel the cold. He did not expect that the lake water would freeze his water, and even the blood flow in his body began to slow down.

The black clothed man did not plan to give up, and continued searching for Dong Wen Feng under the water.

"Eh? What's that?"

Dong Wen Feng suddenly saw a stone door in front of him, he swam towards it.

Surrounding the stone door was a group of fish, their bodies emitting a faint blood-red color. These blood-red fish were filled with a dense killing intent. Even those people who had killed dozens of people did not have such a dense killing intent.

The cultivation levels of the blood coloured fish were not high, each one was merely in the Earth-Rank Late Stage or the Earth Level Peak realm, but there were a lot of them, causing Dong Wen Feng's scalp to go numb.

As the saying goes, even if there were many ants, they could still kill elephants. Moreover, the fish here were not those weak ants.

Just as Dong Wen Feng was about to turn around and leave, he felt another black shadow appear behind him. That black shadow was the person who was chasing after him.

Dong Wen Feng had no other choice but to bite the bullet and charge into the school of fish. After all, he could still live after rushing in.

The fishes did not seem to see Dong Wen Feng, the dense number of fishes quickly lined up into two, and directly went through the middle.

When the black clothed man saw that Dong Wen Feng had found the treasure, he immediately followed along, but the fish had sealed off the road once again.

As the man in black approached the fish, the shoal of fish attacked the man in black.

The black-clothed man circulated his true essence and started attacking the shoal of fishes. Despite the water pressure, every time he attacked, a large number of fishes would die.

Their companion's death did not scare the fish away, instead they fell into an endless encirclement.

Dong Wen Feng had already arrived in front of the stone door. He activated his True Essence and tried to lift the stone door, but he found that it was too heavy.

Seeing that the black clothed man was being stopped by the fish, Dong Wen Feng started to explore the surroundings of the stone door.

A stone door with a tonnage like this would usually have a switch, otherwise, no one would be able to open it.

Seeing that Dong Wen Feng was looking for the switch leisurely, the black clothed man was unbalanced and sent a palm strike towards Dong Wen Feng.

Because the black clothed man had attacked with hatred, his True Essence did not immediately dissipate in the lake, but instead shot towards Dong Wen Feng.

Facing the black clothed man's attack, Dong Wen Feng immediately dodged, in the midst of panic, his hand touched a strange rock on the wall that stuck out.

"Creak!"

He never thought that the stone door that was as heavy as a thousand ton would be accidentally opened by Dong Wen Feng just like that, the black clothed man also did not think that he would be able to quickly rush forward, and dare to enter ahead of Dong Wen Feng.

Those fishes fearlessly rushed towards the black clothed man. Their blood dyed the entire area red. The black clothed man was surrounded by tens of thousands of fishes and was unable to move.
