Ling Feng and Black Panther hid together in the shadows.

His strategy was very simple: follow the murlocs to their gathering place.

He couldn't understand what the fishman was saying, and even if he used his mental power to control the other's brain, it was useless; he still couldn't get any useful information.

Ling Feng patted the black panther's neck and whispered:

"Black Panther, I'm going with this fishman to their lair. You stay here and wait for me!"

Upon hearing this, Black Panther was a little unwilling. He had finally managed to get out of the city, and now he had to wait here. He immediately said:

"Hey boss, I can do it too! Can you take me with you?"

Ling Feng glanced at the black panther and said calmly:

"You have more important things to do. After I leave, you must keep a close watch on this sea area. There might be another group of fishmen attacking from the sea, so you'd better watch out!"

Black Panther's eyes lit up, and his previously listless face regained its expression.

"Boss, I'm here, everything will be fine!"

Black Panther said with a confident expression.

Ling Feng gave him an approving look, then activated his invisibility ability, and his figure disappeared instantly!

Ling Feng arrived at the place where the fishmen were sealed off.

After recovering from his injuries, the merman showed a joyful expression on his face.

He stretched his limbs and carefully looked around, finding nothing unusual.

The fishman's eyes flickered, and then he quickly ran towards the distant sea.

Ling Feng quietly followed behind.

After reaching the surface of the sea, the fish-man ran rapidly across the ice, his speed comparable to that of a king-level superhuman!

This fishman is just an ordinary superhuman, but his speed is truly terrifying!

Moreover, this fishman's physical abilities are also very strong. If it were a human superhuman of the same level, a fishman could probably easily kill a human superhuman!

Ling Feng felt a little heavy-hearted thinking about this.

If these fishmen were to invade the ground on a large scale, it would be a disaster for humanity, and ordinary humans would be wiped out!

The most important thing right now is to find out where these fishmen are from, how many people are in their group, and how strong they are!

This information is crucial!

The fish-man had been walking for half a day, and they were now nearly 500 kilometers from the sea, which was equivalent to the deep sea.

Few people would come to this place, since it's just an endless sea with nothing of value or food, so it would never be discovered.

The fishman reached a reef where the ice wasn't very thick.

Compared to other ice sheets that are five or six meters thick, the ice sheet here is only about one meter thick, which clearly indicates that it had been broken before!

"Could these fishmen have come from this place? It's quite far from the land!"

Ling Feng looked at the reef and memorized its location!

On the other side,

The fish-man cautiously looked around for a while, and after finding that no one was following him, he punched through a meter-thick layer of ice and leaped into the sea!

Ling Feng put all his belongings into his spatial storage and then jumped in as well.

Now, after his body has undergone multiple modifications, even if he doesn't breathe for a day, it won't affect his movements at all.

Ling Feng followed behind the fish-man, swimming deeper and deeper into the ocean.

As we continued to descend, visibility decreased more and more until the entire sea became pitch black, so dark that we couldn't see our own hands in front of our faces.

Fortunately, Ling Feng's eyesight had long since undergone a transformation, giving him night vision. Even in the darkest of environments, there was no difference between his vision and that of daytime.

The merman kept descending, completely unaware that someone was following him.

Ling Feng felt that he had swum more than 2,000 meters downstream. The creatures around him gradually decreased, and there were almost no fish, only soft-bodied creatures!

The water pressure at this depth is extremely high; even a superhuman would be crushed into a pulp!

Just then, the merman suddenly stopped descending.

Suddenly, he opened his mouth and made a strange sound, like a child crying!

After a while, two fishmen swam quickly from a distance.

These two fishmen looked much stronger than the first one. After they arrived, they started chattering away at the first fishman, and no one knew what they were saying!

The two mermen then led the merman from before in another direction.

Ling Feng followed them to an underwater mountain range, where he saw buildings resembling houses, and quite large in area, somewhat like an ancient town.

"Are these buildings from ancient times?" Ling Feng looked at the city with a hint of shock in his eyes.

Ling Feng saw that all of these buildings were inhabited by fishmen, but at this moment all of them were asleep, standing on the seabed with their eyes closed.

Ling Feng looked around the seabed, becoming more and more alarmed with each sight!

After swimming around the underwater mountain range, he discovered that the number of fish-people there had exceeded 100,000.

Moreover, every fishman possesses supernatural abilities, which is not a good thing!

The ocean floor is so vast, who knows if there are other species there?

Ling Feng saw a very tall building in the center of this tribe.

There were many merfolk stationed outside the building, and each merfolk was holding something that looked like a fork.

These fishmen were all very strong and taller than the fishmen he had just seen.

Ling Feng guessed that the people living here were probably the leaders of these fish-men.

He swam quickly towards the buildings.

Although Ling Feng was invisible, his movements still created ripples in the seawater!

The harpoon-wielding fish-men immediately sensed the anomaly and began making strange noises. Although Ling Feng couldn't understand what they were saying, he could see fear in their eyes.

Moreover, their eyes were constantly fixed on the building.

"What's inside that's making these guys so scared?!"

Ling Feng pondered silently for a while.

Let's go in and take a look!

Ling Feng swaggered inside. The fishmen on guard clearly sensed the fluctuations of someone passing by, but they couldn't see where he was.

They were so anxious they were like ants on a hot pan, searching everywhere!

Ling Feng had already entered the large building, which, from the outside, resembled an ancient sacrificial site.

The building has four pillars on the outside, each carved with a different mythical animal...
