Yang Xuan approached the small lake. Around the lake, there was a stone tablet with two big characters engraved on it. However, the stone tablet had existed for a long time, and the handwriting on it became blurred and could not be seen clearly.

When he came around the lake, Yang Xuan found that on top of the lake, there was a light mask to separate it from the lake. In this lake, there are strong spiritual power fluctuations.

"This... Is the power of the beginning?" Feeling the familiar power from the lake, Yang Xuan was stunned. In his impression, Taichu's power only existed at the beginning of heaven and earth, or it was cultivated by monks with various means, but Yang Xuan saw Taichu naturally for the first time.

"It's amazing that there is so much spiritual power and there is no crystallization." Fengzu was also surprised and said that if there were as strong spiritual power as here in other places, it must have become spiritual stones, but here, these spiritual stones are still in a flowing state.

What surprised them most was that even with the experience of Feng Zu and Yang Xuan, they had never had such a strange scene. But both of them can vaguely guess what kind of scene it is.

Yang Xuan and Fengzu passed through the shield around the lake together. This shield is like a bubble. It can separate the sea water from the lake water, but it will not prevent others from entering.

The two entered the lake. Originally, Yang Xuan wanted to continue to separate the lake with Phoenix Sky fire, but was held down by Feng Zu. Yang Xuan found that these lakes would not suffocate. Immersed in them, Yang Xuan could still breathe freely.

After entering the lake, Yang Xuan found that the lake was nearly kilometers deep. When he looked down, he couldn't see to the end.

Just as they were ready to go deeper, a strong wind suddenly rushed towards them. Yang Xuan subconsciously raised his hand and stopped it. When he looked at it, it turned out to be a shark. The shark was translucent, and its color was light green, so it was very similar to the lake. The two were integrated, and Yang Xuan didn't find its whereabouts for the first time.

But then Yang Xuan shot to kill the shark. There was blood flowing out of the shark's body, but it was still translucent light green.

The blood gas of the shark was sucked into Yang Xuan's body, which increased his strength and made him further away from the water avoidance environment.

"This is a good thing. Although these sharks are not strong, their blood is very strong." Yang Xuan said that the strength of these green sharks was no more than the immortal realm, but the blood gas absorbed by the blood sacrifice was equal to a monk with similar strength to Yang Xuan.

Feng Zu raised his hand and pointed not far away. He said to Yang Xuan, "there's more there. It's all yours."

Yang Xuan looked up and saw sharks swimming towards him not far away. These sharks showed their teeth one by one. It seemed that they were angered after smelling the bloody smell of their companions, and the attack became fierce.

However, no matter how cruel they are, their strength is not high after all. In front of Yang Xuan, they are still killed without fighting back, and then become a part of Yang Xuan's strength.

After solving these rotten sharks, continue to dive.

The lake water was as clear as a clear spring. Yang Xuan drank it without any discomfort.

After diving a hundred meters further down, foreign matter drained away the lake and rushed to Yang Xuan. This time, it became a huge octopus. The big octopus waved his hand, and the suction cup kept opening and closing, making people feel a bout of nausea.

Seeing the big octopus, Yang Xuan thought of the Beihai giant demon in Tianbei for no reason. The opportunity was revealed. The octopus was cut into pieces by Yang Xuan again.

After that, several strange sea animals appeared along the way, but they all became the losers of Yang Xuan's men. Unknowingly, they had reached the bottom of the lake.

Fengzu looked around and wanted to find an opponent to fight. Just now he saw Yang Xuan's fierce fight with sea animals, which made his hands itch, but those sea animals could improve Yang Xuan's strength. He was not easy to start, so he had to be greedy on one side.

The bottom of the lake was flat. Although there were some small stones, they did not see the "holy stone" required by the mission. They groped separately towards the front and suddenly hit a barrier.

"This is... A boundary? But why is there a boundary here?" Yang Xuan's hand groped in front of him, and finally determined that an invisible wall stood in front of him. But Yang Xuan has never seen this kind of the arrangement of the boundary.

Just when Yang Xuan planned to ponder over the structure of the border and find a way to crack it, Feng Zu suddenly said to Yang Xuan, "no, let me break it."

Yang Xuan hesitated and nodded. Feng Zu waved to Yang Xuan to step back. When Yang Xuan stepped back to the wall behind him, Feng Zu hit the border with a heavy fist, which immediately brought a strong wave of air and sound. Even Yang Xuan felt dizzy and shaking.

With the a blow, shield trembled violently, but there was no sign of the breaking. But Feng Zu followed with a series of punches. Yang Xuan stared at Feng Zu carefully and found that every time he punched, part of the power attached to his fist would be carried to the next fist by him.

In other words, the power of his punch is that one punch is heavier than another.

After more than ten rounds, a crack appeared in the barrier in front of Fengzu. Seeing this, Fengzu immediately accelerated the speed of punching.

A moment later, the solid border was directly broken. Fengzu turned to look for the trace of Yang Xuan and found that Yang Xuan had been blown to the sky by the Yu Wei he had just punched.

When Yang Xuan fell, they walked towards the border. At the edge of the border, there is a large green circle, which is still flashing. Yang Xuan took a look at the array supporting the operation of the border, and concluded that the border is a powerful means that can repair itself.

However, Yang Xuan didn't know how fast the barrier was restored. He could only enter the barrier with Fengzu as soon as possible.

But as soon as Yang Xuan's feet stepped into the border, he felt a strong crisis, which made his hair rise suddenly, and the Phoenix Sky fire wrapped his whole body in an instant.

Yang Xuan's excited reaction startled Fengzu. The strong and powerful pressure and the vast mind emanated from him, enveloping the surrounding lake.

"What happened?" After some exploration, Fengzu didn't find anything, so he looked at Yang Xuan strangely. Yang Xuan also shook his head. Just now, the sense of crisis came suddenly and left in a hurry. If it wasn't for the goose bumps on his body, Yang Xuan even thought it was his own illusion.

"What mechanism may have been triggered by carelessness?" Yang Xuan thought and could only say so. He and Fengzu moved on and prepared to search the lake carefully.
