Lin Wu dived down with the tablet control device and enlarged the image he saw coming back.

When we went down to fifty meters, there was nothing unusual; at one hundred and fifty meters, there were a lot of fish, animals and debris; after three hundred meters, visibility began to decrease, and at about five hundred meters, no light could be seen.

When we finally reached a depth of about 4,000 meters, the images we received were completely dark, and the sensor scans were also very blurry. We didn't find anything, but there was no point in diving any further.

Several people frowned when they saw this.

"No, we can't dive that deep." Ren Ke said.

They have not received professional training, and it is very difficult for them to dive thousands of meters.

But it seems that they have to look deeper.

According to the data, the known depth of this sea area is nearly 8,000 meters. If the place they are looking for is on the seabed, how can they get there? "Why don't I contact someone now to send a few military submarines over. This thing can dive very deep." Miyano said.

Ren Ke complained: "Why don't you bring some torpedoes? It dives deeper. If we sit on it, it will disappear in a flash."

Miyano spread his hands: "If you want, I can satisfy you. It just so happens that my subordinates have developed a few new ones, but they haven't been put into experiment yet."

At this time, Bo Qi came back, and Guan Chen and Lu Guichi came over together. However, the two of them stayed far away, mainly because Lu Guichi resisted with a dark face.

Gu Shiqing immediately called him: "Cousin, you came just in time. How did you get out of the underground city before? Was it also in the sea?"

Lu Guichi looked around the sea and said, "I don't know. I was seriously injured at the time, and my injuries became even worse after I passed through the underground city gate. I passed out. When I woke up, my uncle took me to other places. But I am sure that the gate is not in the deep sea. There must be a secret in the sea that allows me to pass through."

"Then let's try diving first. Dive as deep as you can. If it doesn't work, think of another way." Gu Siyin said.

The four of them prepared to put on diving equipment.

Miyano went to the side and called for people to bring other usable equipment over.

While Bo Qi was debugging the communication, Gu Siyin and Gu Shiqing stepped forward to check Lin Wu's diving suit anxiously.

Lu Guichi thought for a moment and said, "Wuwu, you can try your tattoo. It is related to the gate of the dungeon, maybe it can guide you to find it."

Lin Wu nodded.

Get ready, the four of them jump into the sea and dive together.

However, when they were just about to descend to 400 meters, they were unlucky enough to encounter three sharks. Fortunately, they brought weapons down with them, and Chongjun quickly brought people down to help them, but after they escaped, their diving suits and oxygen tanks were also damaged, so they had to return to the boat.

The dead shark attracted many giant creatures to come and eat it, so they had no choice but to drive the boat farther away, come back after a while, and try to dive again.

This time they dived to 1,000 meters, but because they could not adapt to the severe deep-sea pressure and had an immune response, they had to go up again. Still nothing was found.

After resting, we dived again and only dived 300 meters further.

Maybe it was because they had become aliens, Ren Ke, Guan Chen and Mo Lang had strong rejection reactions, but Lin Wu was fine.

She asked the three to continue resting, and she changed into diving equipment after she recovered.

Gu Siyin and a few others were worried and wanted to go together, but were stopped by Lu Guichi.

"I'll go, you all wait on the boat." Lu Guichi sighed, "I've recovered a lot now. As long as nothing unexpected happens, I'll be fine in the sea."

Lin Wu looked at the others and knew they wouldn't go any deeper. She could only nod.

Gu Shiqing had no way of objecting, so he got Lu Guichi a new diving suit and stuffed several communicators into his arms.

"If anything happens, remember to press the button to notify us." Gu Siyin stuffed him with a few more alarms.

Lu Guichi didn't know whether to laugh or cry. "I can just take one. I don't need a diving suit. I can breathe in the sea."

He took off his clothes, leaving only his trousers on, and climbed down using the railing.

Gu Shiqing asked someone to get a set of dry clothes.

Ren Ke said weakly: "He just went down like that? No, this makes our careful preparations look useless!"

Guan Chen supported himself on the boat board and sat up: "It's no use preparing any more."

Several people waited anxiously on the boat. After twenty minutes, Lu Guichi didn't come back. Ren Ke and the other two finally recovered.

Gu Siyin was a little worried: "I just pressed the communicator but there was no response. Did something happen to him?"

"...That makes sense." Gu Siyin nodded slowly.

“…”

Lin Wu and Gu Shiqing both had the same indescribable expression on their faces.

After another fifteen minutes, the few people could not wait any longer and were about to go into the sea to look for someone when a person suddenly emerged from the sea. It was Lu Guichi!

Guan Chen immediately let down the rope and went to the stairs to pull him up.

Gu Shiqing also quickly put a thick towel on Lu Guichi.

Seeing that he was shivering from the cold, his face was pale, his teeth were chattering and he couldn't speak, several people hurriedly took Lu Guichi to the cabin room, but they didn't go in. Guan Chen brought dry clothes in to help Lu Guichi.

A few minutes later, Guan Chen opened the door and they went in.

Inside, Lu Guichi was holding a cup of hot water, still looking as if he was almost frozen silly.

Lin Wu made an internal call and asked someone to prepare ginger soup.

Lu Guichi was able to speak again very quickly.

"I dived about 3,000 meters."

"……What?!"

Everyone was shocked.

Ren Ke hissed and inhaled: "You just dived that deep without taking anything with you??"

Lu Guichi hummed and said, "I didn't find anything during my dive. I have a feeling that the entrance is either not in this area or it is deeper."

It is impossible that it is not there. The exact location shown on the map has been converted and measured, and it is right here.

That's at the deepest point.

Bo Qi immediately looked at the satellite remote sensing image map, "Not very good, there is no ridge or anything like that below, only a very deep trench. If we go further down..."

He didn't finish, but everyone understood.

"Okay, I'll make a call right now and ask them to send the submarine over as soon as possible." Miyano got up and went out.

Lin Wu's face also looked a little solemn. She stood up and said, "I'll think of another way." She also went out.

The others were more or less not in the mood, so they told Lu Guichi to have a good rest and left.

Only Guan Chen was left with him.

Lu Guichi felt much better after drinking the ginger soup, but it was hard for him to ignore Guan Chen who was staring at him.

Thinking of what happened in the past two days, Lu Guichi felt uneasy and turned his head away: "Get out too! If you... I will really hit you, don't think I won't beat you up!"

Guan Chen asked, "Why are you afraid of the cold?"

Lu Guichi paused.

"When I went back to Lingnan, you also dived in the sea. You were fine at that time. You were also said to be fine even at a depth of several thousand meters, and you are not afraid of the cold. What's wrong now?" Guan Chen frowned and looked at him, his eyes slightly tightened, "Are you really in trouble?!"

Lu Guichi was silent for a few seconds and said, "No. It's winter now. You felt the temperature on the bottom of the sea just now. I dived so deep and haven't fully recovered yet, so it's normal to feel cold."

He looked up at the man, "I'm still a human being. Don't you think I'm a normal person who gets cold?"

Guan Chen was immediately panicked and at a loss: "That's not what I meant!"

On the other side, Lin Wu went up to the deck, staring at the sea in a daze, thinking about what to do next.

Suddenly, Lin Wu inadvertently glanced and noticed that the sea surface not far away seemed to be a little strange, as if there was a whirlpool slowly gathering.
