I practice martial arts by adding skill points in modern city-Chapter 564: 【187】Final reward, genetic limit increase_3

"I know my limits." Wang Longhu jumped into the sea without looking back.

His feet stood steadily on the surface of the water. As his inner strength burst from the acupoints on the soles of his feet, the seawater was instantly churned up, creating a small whirlpool.

The mutated giant tooth sharks couldn’t even get close to Wang Longhu’s body before being torn to pieces by the vortex infused with inner strength.

Seeing that there were no obstructions, Wang Longhu dissipated his inner strength and dived into the whirlpool, disappearing without a trace.

Looking at the blood-red surface of the sea, Jostar felt a bit tempted.

As the saying goes, the difficulty of any task lies in the absence of the first person to venture out.

Once that person appears, they act like a guidepost, attracting a large number of followers.

Jostar was in such a mindset at this moment. Before Wang Longhu appeared, he was apprehensive and didn’t dare to take the risk of diving.

Even if this expedition to the Kukulkan relic yielded nothing, his first priority was preserving his own safety.

But now that Wang Longhu had moved first, Jostar felt an irresistible urge rising within him.

His courage had increased considerably.

"Mr. Wang, wait for me, I’ll join you!"

Jostar shouted, hastily jumping into the sea to follow him.

The sea beneath the surface was extraordinarily dark.

With the naked eye, one couldn’t see beyond ten meters.

This distance of ten meters was merely a momentary affair for a top-tier Hunter.

So exploring beneath the sea was truly a dangerous endeavor.

But for Wang Longhu, it was different. His spirit could perceive the nearby terrain and any movement.

The seawater acted as a medium, much like an electrocardiogram. 𝒇𝒓𝙚𝒆𝔀𝓮𝓫𝒏𝓸𝙫𝓮𝓵.𝓬𝙤𝙢

Without any movement, the flow of seawater remained smooth and regular.

But once something started moving, it would instantly cause fluctuations, thereby alerting a sensitive being.

Ready to take preemptive measures.

Relying on his spirit acting like radar, Wang Longhu scanned the surrounding area as he continued to dive deeper and soon reached a depth of 500 meters.

At this depth, he discovered that the small island they were on was actually the peak of an underwater mountain.

And the height of this mountain was well over 500 meters, sinking further below.

"No signs of life, and no door. What’s the key to leaving this room?"

Wang Longhu looked slightly puzzled.

Before entering the Kukulkan relic, Ponken Wilson had already shared some of the keys with him.

The key to leaving a room was to either solve a puzzle, defeat a guardian, or find a physical door.

The second and third methods were the most common; the first method had been encountered by the Wilson family only three times over the years.

But Wang Longhu faced an endless expanse of ocean, with no end in sight.

Whether it was the first or third method, it presented a very troublesome situation for him.

It implied wasting a significant amount of time, a losing trade.

"I landed on this island, and Jostar also landed on this island. This can’t be a coincidence. The door must have some kind of connection with this island. How about I head straight to the base of this mountain to see what’s going on?"

Wang Longhu thought to himself and quickly made up his mind, swiftly diving downward.

meters, 2000 meters, 3000 meters...

At around 3200 meters, Wang Longhu finally landed on the seabed, where it was so dark he couldn’t even see his fingers.

Looking upward, it was complete darkness, with extreme silence all around.

Wang Longhu suddenly turned to one direction and punched out, and the next second, a giant shark’s head collided with his fist, exploding instantly.

Another giant tooth shark.

"These giant tooth sharks seem to be guarding something," Wang Longhu mused to himself.

In no time, Jostar finally descended in front of Wang Longhu.

Sure enough, he was a metal Super Martial Artist, mutated with cell energy.

With a series of operations, all the minerals in the seabed rose under his control, then transformed into a metal wall that enclosed the entire base of the mountain.

The water inside was expelled by air pressure, quickly forming a sealed off space.

"My goodness, I’ve never been in such a strange room in my life. How does the Kukulkan relic hold such a large space internally?

Aliens, there must be extraterrestrials in this universe." said Jostar with a sigh of relief, taking out a glow stick from his pocket and lighting it.

This glow stick must have been a product of the latest technology.

The brightness was so intense Wang Longhu couldn’t bear to look directly at it; it was like a man-made little sun.

But thanks to this glow stick, both of them clearly saw the situation there.

Without the seawater, the seabed was full of damp silt and rocks, with many small fish, shrimp, shellfish, and algae.

Seeing these living beings, Wang Longhu was incredibly shocked.

This suggested that this was not just a room.

But rather a small world with its natural circulation, self-sufficient in its production and disposal!

Otherwise, it would be impossible for such small life forms to exist in a confined space.

"The alien civilization that built the Kukulkan relic must have reached an incredibly advanced level," Wang Longhu murmured.

What did this compare to?

The current human civilization on this planet couldn’t even build a city underwater; issues with oxygen, water pressure, transportation, and safety were all unsolvable.
