The underwater ruins are mottled with strange rocks, and few schools of fish or creatures roam around them.

As soon as a creature approaches, there is an illusion that it can hallucinate a creature, and it is precisely because of a biological wave that is emitted from time to time in the ruins that stimulates and affects the nervous system of the creature.

It is precisely for this reason that although the people of the United States discovered the existence of this ruin, they did not find the slightest discovery when they sneaked here many times under the interference of that unbreakable biological reflex.

Even, they didn't even get close to the core area of this ruin, so naturally they didn't know what was hidden in this ruin.

As for Yu Xiaohu, in the control room on the Ichthyosaurus, his eyes have been following the exploration process of those robot teams, and when he went deep into this ruins, some of the things and scenes he saw made him more convinced that what was hidden in this ruins should have a great relationship with the base island.

He had a gut feeling that what was hidden in this ruin was the lost part of the base island.

As a result, the robot team gradually penetrated into the core of that area.

Although it will be interfered with by the biological communication mechanism, after Yu Xiaohu asked the signal of this mechanism collected by the robot team to feed back to the base island, the base island deciphered this biological communication mechanism in the shortest possible time.

The information contained in this extremely weak biological signaling mechanism deciphered can be summed up in only one meaning, that is, it indicates the urgent need for energy to remain dormant after the module's contact with the main module is interrupted.

After Yu Xiaohu got the prompt from the base island, he knew that what was hidden in this ruin was a strategic reserve module lost by the base island.

Because the energy here is exhausted, after entering dormancy, all signal sensing connections between him and the outside world and the base island are completely broken, and he can only rely on the mechanism of the increasingly weak biological instinct to send a very weak communication mechanism to get in touch with the main body of the base island in this way.

After the base island deciphered the very faint signal of the biological communication mechanism sent here. The exploratory robot team quickly incorporated this biological communication mechanism into the intelligent core library.

As they explore, they will emit biological signals that match the weak mechanism, so the interference in the ruins will quickly disappear, and the weak communication mechanism will form a kind of guide, gradually guiding the robot team to the core of the ruins.

Soon, Yu Xiaohu saw through the screen that the machine team had gone deep into the core. While there you will encounter some large and small, aggressive sea creatures and some plant creatures.

It's just that those creatures have only undergone some slight changes at most, and have not formed mutations, and they are not as powerful as the mutated horseshoe crabs or electric eels that are a little perverted.

Therefore, although these creatures will form an obstacle, for the exploration robot team, the robots only use a biological weapon to shoot once, and those creatures are all destroyed, without the slightest difficulty.

Some of the creatures were cleared, and their corpses were collected as resources by the Collector Robot, and the Engineer Robot emptied a nearby area. A huge crater appeared there.

The pit is covered with all kinds of silted debris and some parasites, and even some have failed, which at first glance are the kind of deep-sea probes developed by humans.

There are many types of detectors, but all of them have lost their effectiveness, and after the robots have completely destroyed the relatively rudimentary detectors for safety, the engineering robots have begun to dig and clean up the huge crater.

About twenty minutes passed. The crater was cleared, and two reconnaissance droids entered the inclined crater. And they found that there were many holes in the pit.

After inspection, those were all craters formed by the firing of weapons, of various calibers and sizes, and further down, there were the bones of some sea creatures.

"Hey, how can there be bones of land creatures?"

As the robot team passes through the area of bones where sea creatures have accumulated and halfway forward. There were skeletons too, but they weren't sea creatures anymore, and the robots used the skeletons to detect that they were land creatures, some resembling the bones of orangutans or apes.

The bones of these land creatures are only a few few, not many. But Yu Xiaohu became interested in these creatures that appeared in the underwater ruins.

As the robot continued to go deeper into the hole, Yu Xiaohu asked a robot to collect a piece of that skeleton for more detailed examination, and soon the detection data was sent back to the Ichthyosaurus.

It's just that Yu Xiaohu was very surprised when he saw these data.

Because from the data analysis characteristics, it is a creature belonging to an American orangutan, but through the detection of the bones, this creature is very large, the bone is extremely fine, and there has been a certain degree of genetic mutation.

In particular, this creature also has an internal respiratory system that allows it to live both on land and in the ocean.

But why did this creature appear in this underwater ruin?

With this question, Yu Xiaohu didn't check the information again, and turned his attention to the robot exploration team.

I saw that the reconnaissance robot had already collected the data explored by the inclined giant pit, and there were few bones of creatures in the innermost part, but at the end of the pit there was a 'thing' wrapped in a ball of marine parasites, with a strange body shape and appearance characteristics, and slowly wriggling.

In particular, the 'thing' obviously extended from the inside like a tube, and after only a preliminary scan of the reconnaissance robot, Yu Xiaohu was surprised, it turned out to be a cannon barrel made of biosynthetic materials.

Surprised, followed by a deep curiosity, Yu Xiaohu ordered the robot to start approaching the thing, and then further detect it.

After testing, the outline and appearance of the thing were also displayed in a digital way, and the overall appearance looked like a combat vehicle, but it was significantly smaller than the average combat vehicle on Earth, but it weighed seven tons.

But in fact, the image of this thing is likened to a frog with a retractable tube in its mouth, with limbs but significantly longer hind limbs, as if it could walk upright.

After the robot detected that this kind of thing was not threatening, Yu Xiaohu asked the robot to clean up the parasites that were parasitic on his outer surface, and soon revealed his true colors.

On the surface, it did look like a small chariot, but it didn't have wheels or tracks, just four retractable mechanical arms, and he stood like a mech, supporting the crater just enough to block the passage.

According to the robot's information retrieval, Yu Xiaohu could determine that this was indeed a mecha, but after the parasites on his body were cleaned up, he saw a large hole in his chest.

After the robot stretched the explorer into the large hole to scan, Yu Xiaohu found that the mecha seemed to be left with only an empty shell, and all the devices inside had disappeared, and there were traces of violent dismantling. (To be continued......)
