Behind the stalactite pile, there is a crack that Liu Ying was dragged away by a giant octopus. The three fish-men had already chased after them.

The crack is neither wide nor narrow. Liu Ying or the figure of the fish man, shuttling through it will not feel cramped. Luo Youcheng is fat, and there is a respirator on his back, and it is very embarrassing to walk through the gaps, either the stomach is blocked, or the respirator is stuck.

Because it is far away, the intercom system cannot hear the sound. Luo Youcheng regretted that his intestines were all green, and the delay was enough for the giant octopus to kill its prey. And the crack is so long, if it encounters another fork in the road, who knows where the octopus will drag Liu Mei to? If Liu Mei has a mistake, he will regret it for the rest of his life.

Fortunately, there is no fork in the cracks. Luo Youcheng passed through this crack of about 200 meters, and it took five minutes. Two meters away from the exit, the intercom system in the breathing mask was reconnected, and he finally heard Liu Ying's cry for help, and the big stone in his heart fell halfway.

At the other end of the crack, there is a small blue hole, and the scale should be a five-kenken blue hole. This hole is the smallest and only more than 30 meters deep.

Squidward is still holding Liu Ying hostage, and the three fishmen surround it. They were in a very strange state at this time, their whole body was red, a bit like angry memes. Their bellies shook rhythmically and rapidly, but they didn't make a sound. The octopus seems to be scared, but it is still reluctant to give up its prey. The wrist was no longer wrapped around Liu Ying, and only sucked her with a suction cup, not letting her leave.

Luo Youcheng sensed Squidward's panic, and the fish-man's violent intimidation of him was very effective. Luo Youcheng was about to sacrifice his mind power when Dajana suddenly disappeared from the spot, and her body became as transparent as water.

When the fish-man woman reappeared, she was already beside the giant octopus. Her hand was like a fork and pierced into the compound eye of the octopus. The thorn was a little deeper, and when her hand was pulled out, it brought out a cloud of ink, like a splash of ink on a drawing paper, but it was quickly diluted and dispelled.

Liu Ying, who was rescued, calmed down, and to Luo Youcheng's surprise, she didn't cry. However, Luo Youcheng anxiously asked long and short questions, asking east and west, for fear that his daughter-in-law would be scared stupid.

Liu Ying said: "Brother Cheng, I'm fine." ”

Liu Ying was not injured, and the well-protected diving suit protected her well, only a dimple appeared on the top of the mask, which was left by Squidward's palate when he tried to stuff Liu Ying into his mouth.

Luo Youcheng was frightened, if it weren't for the interference of the three fishmen, maybe it wouldn't be as simple as leaving a mark, he didn't know if the deep diving anti-stress suit could help Liu Ying carry it for five minutes. He stumbled and comforted Liu Ying in the intercom system, saying sorry for his reckless decision.

Liu Ying said it was her fault. Luo Youcheng thought she was talking the opposite, and became more and more uneasy.

Liu Ying said to him: "I'm too useless, Brother Cheng, teach me to hunt, I should have this ability." ”

She also said that the feeling of being treated as prey is actually not so bad. At least she tried to resist, and she forked the octopus a few times with a stalactite, and it was all stuck to her wrist, in the wrong place. If she the eyes of an octopus like Dajana, she should be able to overcome it.

Luo Youcheng has been feeling Liu Ying's emotions, and only after making sure that she really doesn't mean to blame, he relented.

Liu Ying really realized her shortcomings. She has speed, strength and excellent coordination. In fact, in the month she followed the knife shop to learn swords, she was often praised by the second sister and the knife shop, saying that she was very talented. Her only weakness is timidity, and as long as she can overcome her fears, self-preservation is not a problem.

Luo Youcheng asked Liu Ying if she needed to interrupt the expedition and go back to rest. Liu Ying didn't agree, she knew that as long as she retreated, she would continue to be a left-behind daughter-in-law in the future, staying up at home and looking forward to the return of her brother. After she handed over the leadership of farming to Song Shizhen, this woman's obsession with accompanying Brother Cheng to take risks was extremely strong.

Luo Youcheng sincerely thanked the three fishmen, promised not to make hasty decisions, and implored the three fishmen to help take care of Liu Ying.

When the five of them return to the Great Kenken Blue Cave, the three fishmen become very cautious, Dagana stays by Liu Ying's side, and Gagawa and Ren Ina inspect every corner of the cave to chase away the sea creatures hiding inside.

The Great Kenken Cave is 80 meters deep, and the light here is already very dim, like dusk when the sky is about to get dark. If you don't turn on the lights, you can barely see. Such light has no effect on the fish-people at all.

A ship lies horizontally at the bottom of the cave. Luo Youcheng opened the monocle, and the data of the ship was quickly fed back. The ship is 82 meters long, with a displacement of 312 tons, and the hull material is suspected to be a light alloy material treated by a special process, which is extremely corrosion-resistant.

The database built into the monocle is not large, and the monocle uses the word "suspicious" to interpret the mission of this ship - submarine hunting, a small surface combat ship with anti-submarine weapons as its main equipment. It has only one target, a submarine hiding in the deep sea. The ship suffered heavy damage to the bottom and stern and appeared to have been hit and sunk by a submarine hiding inside the Blue Hole.

Luo Youcheng didn't care about the reason for the sinking of the hunting submarine, after all, this was an ancient ship, and he came with the mentality of hunting and adventure.

Before Luo Youcheng and Liu Ying entered, the three fishmen had already checked the inside of the boat to make sure that there were no dangerous creatures.

Luo Youcheng became more and more curious about the fish-people, and at eight times the atmospheric pressure, they did not feel any discomfort; The lack of light in the boat did not hinder their movements. Dajana's explanation was that they had a sonar system that would help them avoid obstacles, and that they were used to living on a wreck. But Dajana also said that they rarely go out at night, because there are too many unknown dangers lurking in the sea late at night.

Luo Youcheng and Liu Ying are more accustomed to observing things with their eyes, so they turn on the lights and explore room by room. The bones in the ship had long since been cleaned up, and there was nothing in it that was an eyesore. The fishmen say that this is what they did when they found the wreck. Perhaps before they found out, there were ancient divers who cleaned the ship. Therefore, there will also be nothing of value in the hull of the ship.

The combat units on the boat, such as anti-submarine [torpodo] tubes and depth charge launchers, are damaged, and even if they are still usable, it is meaningless. Luo Youcheng has no idea of naval warfare now or in the future. If he were an archaeologist, the ship might still have some value, but he clearly wasn't.

Why is it considered to be an ancient ship? Luo Youcheng picked up a military card.

The military tag was left at the foot of the bed, and Luo Youcheng inadvertently discovered it when scanning under the bed with ultra-low frequency consciousness waves. Instead of using more skilled telekinesis, he used ultra-low frequency waves with longer wavelengths, because the latter are much less attenuated in the water and can be detected at a much greater distance.

The badge is rectangular, rounded at both ends, with etched text on both sides, with personal information on the A side and information about the service on the B side. The owner of this medallion is Evan Miller, born in 2168 and belonging to the Royal Australian Navy. From this, it can be concluded that this is a ship that entered service with the Navy at the end of the 22nd century.

The military card gave Liu Ying the inspiration for entertainment, and the woman began to drill the legs of tables and beds, open cabinets and drawers, room after room, trying to find more interesting things. Luo Youcheng and the fish people were reduced to playing together.

Two hours later, Liu Ying counted the trophies and laid them out in bits and pieces, including cockades, crystal photographs, all-steel lighters that had been corroded to the point where they could not be seen in their original form, buttons that had fallen from their uniforms, and old pens......

The three fish-people have to admit that the people on land are very good at playing, and the game of treasure hunt is much more interesting than their game of hide and seek.

Liu Ying has had enough, and suggests hiding these "treasures" again, so that the next time the Kendawa people come, they can also play the same game. Her suggestion was echoed by the Fish-Man.

Luo Youcheng instructed the fishmen to protect Liu Ying, who was "hiding treasures" everywhere, and he went out of the wreck alone. The cave was still very large, and he wanted to look around to see if anything else had been found.

His ultra-low-frequency consciousness wave slowly swept through the water, and he was disappointed. The bottom of the cave is very clean, and there are very few aquatic plants and aquatic animals. Halfway through the exploration, he decided to give up.

He turned around and swam towards the wreck, and suddenly saw a point of light more than twenty meters away from the stern. He dived quietly, and when he was less than ten meters away from the point of light, he could see that it was a glowing fish. The glowing fish turned and fled, burrowing into a crack at the bottom of the hole.

Luo Youcheng subconsciously used the consciousness wave to scan the surroundings, and then he was stunned. His wave of consciousness disappeared into a small stone mountain, as if sucked by something. Luo Youcheng tried to increase the output of the consciousness wave, but when the consciousness wave reached the stone mountain, it was like a mud cow entering the sea and disappearing without a trace.

Luo Youcheng removed the rubble from above, revealing a broken hull. This part of the hull was detached from the tail end of the ship and was shaped like a giant flush toilet with the water tank removed, and it turned on its side to the ground. Most of the "toilet seats" are the same color as the hull, which is light blue, and in the center of the "toilet seat" there is a tabletop-sized black spot, which is very pure.

The demon is the big black spot, which can not only absorb consciousness waves, but also will not reflect a trace of light when the light shines on it. If you look closer, you can only see the bottomless black, and you can only see its shape by comparing it with the surrounding hull. It is like a black hole, greedily absorbing visible or invisible electromagnetic waves.

It differs from a black hole in that it has a physical body. You can touch it, feel its rough texture, and don't worry about your hands being sucked into it.

Luo Youcheng subconsciously thought that this was a treasure, and he kept inputting consciousness waves into the black spot, trying its absorption limit. But that thing is a bottomless pit that never seems satisfied. Twenty minutes later, Luo Youcheng, who was mentally exhausted, swam to the water and made a call to Shi Xiangyun.

Shi Xiangyun also felt that this thing was not simple, so let him try more. A few more tries might be able to find the tipping point and see what it really does.
