Evolution from the crocodile

Lu Chen quickly swam out along the gap and soon came to the crack in the center of the ring-shaped pit.

He did not enter it immediately, but used the touch cells on the surface of the scales to carefully sense the changes in the water flow. Since his evolution to level 4, Lu Chen's body has also undergone earth-shaking changes. The detection sensitivity and range of touch cells have been increased several times.

It is no exaggeration to say that he can clearly perceive the message sent by a small fish more than ten centimeters long within a hundred meters.

Soon, Lu Chen received subtle abnormal fluctuations from the depths of the crack.

After confirming the specific location, he flicked his tail and swam into it.

As expected, the electric eels also found prey entering the cliff crevices. They emerged from the holes one by one and quickly swam towards Lu Chen's location.

court death!

Before the other party started to discharge, Lu Chen took the lead.

His mouth opened wide, and another ball of blood-colored compressed energy bombs spit out.

With Lu Chen's current strength and sufficient physical strength, it would not be a problem to fire three or five compressed energy bombs in succession. In addition, the amount of energy injected into it can be controlled according to the actual situation.

It was no different from the previous giant algae tentacles. Many electric eels were blown to pieces before they had time to react. Some of those further away were still in a state of dizziness, although their bodies were well preserved.

Take advantage of his illness and kill him!

Lu Chen quickly swam close, waving his sharp claws one after another, killing the surviving electric eels one by one.

Being so close, he finally saw clearly what these guys looked like.

They are nearly two meters long, and their gray-black round bodies are in the shape of a stick. The head is covered with pits and pits, the mouth is full of sharp teeth, and there are several tentacles at the corners of the mouth. The pelvic fins extend from the gills to the tail.

Suddenly it looks like the snakehead in Tamsui, ferocious and fierce.

After the hunt, Lu Chen opened his mouth and swallowed a piece of flesh and blood.

I have been eating ordinary animals these days, and I have long since become tired of it.

The prehistoric mutated electric eel can provide 2,600 energy points...

It is true that the electric eel has mutated, but what does prehistoric mean when it is added to the system identification? Lu Chen immediately thought of the prehistoric salamander in the underground cave.

According to the previous definition of prehistoric creatures, these two species should refer to creatures that lived before the emergence of human civilization.

However, Lu Chen felt that it was not that simple. According to this concept, sharks should also be regarded as prehistoric creatures.

After all, sharks appeared hundreds of millions of years ago.

However, the tiger shark I hunted before did not receive a similar text prompt.

Lu Chen couldn't find the answer, so he simply suppressed the question in his heart for the time being and continued to sneak down along the cracks in the deep sea.

Without the attack of the mutated electric eel, everything went smoothly and he dived straight to the bottom of the crack.

Lu Chen originally thought that the cold seabed was completely dark, but the result was unexpected again. After the crack zigzagged downwards for hundreds of meters, it suddenly became wider, and there was a faint light coming from below.

Lu Chen entered it and discovered that there were many strange algae emitting blue fluorescence growing on the surrounding reefs. The light I saw before was exactly what they emitted.

What the hell is this place?

Seeing the huge stone gate standing abruptly in front of him, Lu Chen once suspected that he was suffering from diving disease and had hallucinations before his eyes.

In the cracks on the seabed hundreds of meters deep, there is a gate more than ten meters high and seven or eight meters wide, made of large boulders.

With the help of surrounding fluorescence, Lu Chen could see very clearly. Although the surface of the boulder is covered with a thick layer of sand and its original appearance is no longer visible, judging from its shape, it is definitely a man-made object.

Lu Chen stretched out his sharp claws and scratched randomly on the surface of the boulder. Sure enough, there were traces of carvings on it. I don’t know what kind of stone this door is made of, it’s hard.

After removing the sediment above, no traces of seawater corrosion were found.

There are some complex patterns and words carved on the surface of the boulder. Lu Chen looked closely for a moment to confirm that he didn't understand.

However, he had a vague guess in his heart that this underwater stone gate was definitely not made by Blue Star humans.

The reason is very simple. Ancient people did not have this ability, but modern people have the technology, but no one has the time to dive into a trench hundreds of meters deep to build a weird gate.

Or a mermaid?

Lu Chen thought of the mermaid skeleton found in the giant algae jungle.

Previously, he thought these guys would live in the cracked seabed, but now he used fluorescent algae to explore the surroundings and found no living creatures, not to mention no spiritual stones as he expected.

How can it be?

Lu Chen was a little unwilling to give up. He searched back and forth on the bottom of the sea to confirm that there was not a single spiritual stone.

Or was there originally a spiritual stone here that was swallowed by those electric eels?

Lu Chen's heart moved slightly and he immediately used his claws to dig.

Soon, he sensed a familiar aura emanating from the ground.

One, two, three... Looking at the spiritual stones revealed in the sand, Lu Chen was naturally very excited. My guess was absolutely correct. Wherever there were changes in creatures, nine out of ten cases were related to spiritual veins.

These spiritual stones are dark red in color, very similar to those in the mermaid necklace.

First-grade spiritual stone, can provide 386 energy points

First-grade spiritual stone can provide...

After swallowing a few spirit stones, Lu Chen discovered that although they were also first-grade spirit stones, their quality was slightly inferior to those produced in Shentan, and their energy points were lower.

In the next few days, Lu Chen transformed into a miner, diving into the water to dig for spiritual stones from time to time.

As for the stone arch, he studied it for a long time and had no choice but to give up. It really didn't make sense.

What made Lu Chen even more miraculous was the giant algae jungle. Every time he dived, the other party would give way to the passage.

It seems that these guys have really high IQs. After being bombarded and educated by compressed energy bombs, they actually completely remembered their own breath.

After staying here for almost a week, the shallow underground spiritual stones have been swept away. As for the spirit stone veins that must exist in the deeper layers, Lu Chen could not continue mining.

He had envisioned using compressed energy bombs to blast open the reef and then dig deeper.

After thinking for a while, I gave up on this tempting idea.

The main problem is that the seabed terrain is complex and I don’t have any professional mining knowledge. If the mine collapses after entering it, it may be buried deep under the sea.

It's not worth it for a few spiritual stones.

After being out for such a long time, it's almost time to go back to Shentan Valley.

During this period of mining at the bottom of the sea, he had an inexplicable feeling in his heart that something big was about to happen.

Half a day later, Lu Chen re-entered the primitive jungle of Madura. Afraid of human surveillance near the river mouth, he deliberately detoured hundreds of miles away and quietly entered the water from another river.

After spending two days sleeping day and night, Lu Chen returned to the underground cave.

I felt relieved when I saw that all four little guys were fine.

It seems that those humans focused their attention on themselves and did not come to search near the valley. Or maybe I have looked for them, but I just didn’t find that there are three unique crocodiles living in the underground caves.
