He immediately packed his things, installed a seawater separator in the dinghy, and connected the hydrogen output pipe into the engine room of the dinghy. Pen ~ fun ~ Ge www.biquge.info hydrogen, as a combustible gas, is one of several spare fuels that can be replaced as fuel for dinghies.

After Chen Tianci made sufficient preparations, he immediately drove the dinghy and continued to drive towards the Manila Trench. Following the map, he followed the map and headed south along the Luzon Trough, where he soon reached a deeper trench.

This is where the Manila Trench and the Luzon Trough meet. Chen Tianci carefully checked the surrounding situation through the monitor while checking the map, and began to look for areas that could be built as temporary habitats.

In the deep water, Chen Tianci released the surveillance robot from the dinghy, slowly walked on the volcanic rock, and transmitted the surrounding situation back to the dinghy through the measuring instrument.

Chen Tianci sat in the driver's seat, analyzing the information returned by the surveillance robot one by one. But he had no experience after all, so after analyzing it for a while, he felt a big head for a while.

At this time, he couldn't help but think of Shen Ziyi again. He couldn't help but think: "If Ziyi is here, with her brain, she will definitely be able to immediately analyze where to camp." Alas! ”

Chen Tianci let out a long sigh, waved his hand to dispel these mixed thoughts, and concentrated on inspecting the surrounding terrain. Time passed little by little, but Chen Tianci did not find the ideal camping spot.

He shook his head slightly, and was about to leave, when the dinghy was suddenly enveloped by a powerful force and rushed towards the nearby Manila Trench.

"Oops! This is an undercurrent. Chen Tianci was startled, and hurriedly steered the dinghy to rise. But he suddenly found that the dinghy could not rush out of this force. Chen Tianci was so shocked that he could only watch as the boat he was riding in was swept into the Manila Trench by the undercurrent under the sea.

He clung to the gauntlets in the dinghy and curled up together, protecting his head and neck. The emergency measures on the dinghy have been activated by him, and at this time, a faint film has been attached to the dinghy, resisting the suction force of the outside world.

The dinghy was in the undercurrent, as if it was caught in a whirlpool, spinning wildly. Chen Tianci only felt that the world was spinning, and the bones in his body were almost falling apart.

After a long time, Chen Tianci felt that the dinghy seemed to have hit something, and it actually broke away from the undercurrent and slowly stopped. He hurriedly clicked on the screen, released the probing robot, and looked around.

At this glance, he was stunned. On the display screen in front of his eyes, a strange building appeared. The building resembles the pyramids of Egypt and has a triangular spire.

It is about 300 meters high, and at its widest point it reaches more than 500 meters. Directly in front of it, a statue stands. Chen Tianci controlled the surveillance robot, approached the statue and looked at it carefully for a long time, only to realize that the statue was carved with the image of a mermaid.

"God, how can there be such a thing here?" Chen Tianci couldn't help but have such a thought in his mind. But before he could think about it, he saw something even more shocking to him.

The footage transmitted by the surveillance robot farther away clearly shows that behind this pyramid, there are many smaller pyramids, as well as some scattered buildings.

"It's... This... It's an entire undersea complex! Chen Tianci exclaimed. He stared at the buildings on the screen, and said to himself in some anger, "Damn, I can't be in a city-state." It's going to be terrible. ”

Chen Tianci didn't say a word at the moment, and controlled the dinghy and climbed rapidly, wanting to escape from this place immediately. He didn't want to face a patrol that suddenly appeared. You know, this area is all the rebels' sphere of influence, even if it's just a small city-state, it's not something he can fight against now.

But at the moment when Chen Tianci was driving the dinghy and wanted to escape, a huge question suddenly flashed in his mind. "No, the cities under the sea are all aqueous and non-existent, how can this place not be? Could it be..."A bold and imaginative idea suddenly popped out of Chen Tianci's mind.

"Could it be that this is the city inhabited by the legendary undersea people?" The more Chen Tianci thought about it, the more he felt that this situation was extremely likely. He immediately stopped the dinghy and slowly descended back.

As long as he was not facing the rebels, Chen Tianci would not feel afraid. After all, he didn't have any trouble with the undersea people. Although he had never seen an undersea man, he had never heard a report of an undersea man attacking a human since he entered the deep sea to survive.

Because the undersea man is still an unknown mystery to modern humans. People have never really seen this mysterious race until now.

Although humans and undersea people are also called humans, people who hide in the deep sea from the land to survive still think that they are orthodox humans, and other creatures called by humans can only be called humanoids.

Chen Tianci cautiously lowered the dinghy and docked on the rocky ground. He waited for a while, but there was no sign of any humanoid. The surrounding sea water is only the noise of the creatures under the sea.

Chen Tianci waited for a while, and when he saw that nothing happened, he quickly changed into a diving suit and entered the sea water through the water trap. He slowly swam up to the mermaid statue and looked at it carefully for a while.

The statue is full of algae endemic to the bottom of the sea, and occasionally a deep-sea fish or two swim past the mermaid statue and pick up a small amount of parasitic algae from the mermaid statue.

Chen Tianci observed for a while, saw that there was nothing abnormal, and was about to walk towards the pyramid in the distance. Suddenly, out of the corner of his eye, he caught a glimpse of a line of handwriting on the base of the mermaid figure.

Chen Tianci hurriedly walked over and leaned over to take a closer look. But in the dark environment, it was difficult for him to read what was written in the dim light.

Curious, Chen Tianci quickly swam back to the dinghy and fetched the lighting equipment. There are many lighting equipment under the deep sea, and Chen Tianci's dinghy carries only one portable searchlight. The searchlights are waterproof and are made specifically for deep-sea exploration.

Chen Tianci carried a searchlight and quickly swam back to the mermaid statue. He turned on the probe light and shone it in his memory. The searchlight was well lit up and immediately illuminated the area.

But before Chen Tianci could see that line of handwriting, suddenly, a behemoth came out of the rock behind the mermaid statue and pounced towards Chen Tianci.
