Xia Qing and Lian'er were clinging to the cave wall, and the fat man covered them behind him, watching Gao Chao and Hua Ye slowly swim towards the darkness ahead.

Gao Chao is in front, Hua Ye is behind, and both of them are holding long knives and daggers in their hands, but this kind of cold weapon is almost not worth mentioning in such a deep sea.

didn't swim far, under the illumination of the diving lamp, Gao Chao found that there was a situation on the cave wall in front of him, and Hua Ye also saw the clue, and the two of them looked at each other, and then they understood.

It turned out that in the circular cave in front of them, there was a large hole above and below the cave wall, and they slowly moved forward, shining up and down with a diving lamp, but found that both above and below, there were black holes in the two large holes, and there was no end in sight.

Presumably, the upper and lower ends should be a passage connecting the top and bottom of the giant tower, and I don't want to be pierced by Hou Yi's arrow back then, which left such two big openings, one leading to the top of the tower and the other leading to the bottom of the tower.

From this point of view, the black shadow that flashed by just now is likely to have directly entered the opening above from the passage below, so it will disappear after a while.

Thinking of this, Gao Chao and Hua Ye both used diving lamps to take a good look at the passage to the top of the tower. After looking at it for a long time, but there was still nothing, the two of them glanced at each other, and then made some communication, thinking that the black shadow just now was probably just a sea creature living here, and there was no need to think about it anymore.

So they used the diving lamp to send a signal back to the fat man, and the fat man saw that there was no danger, so he took Xia Qing and Lian'er to swim forward together.

The five people floated between the upper and lower passages, the top and the bottom led to two directions, Gao Chao gestured at Lian'er, meaning to ask her, whether she wants to go up or down now, you have to choose one of these two directions.

Since they hit the water, each of them has a diving goggle on their face and a respirator in their mouth, making it difficult to see everyone's facial expressions.

Lian'er swam between the upper and lower passages, and Gao Chao gestured at him, but she was not looking at Gao Chao at all.

Only then did everyone notice that Lian'er was looking up at the entrance to the dark passage leading to the top of the tower.

Gao Chao and Hua Ye glanced at each other, both a little at a loss, and Hua Ye pointed upwards again, meaning to make sure that Lian'er let them go up.

But who knew that at this millisecond interval, I only felt that there was a sudden turbulence around me, and everyone was swept up in it, and it was involuntary to turn their heads in the water, and it was difficult to control their bodies anymore.

Everyone panicked, but before they could react, they saw a black shadow around them from top to bottom, quickly passing by everyone, and in a trance, they disappeared again.

Frightened, everyone scattered in all directions, Gao Chao tried his best to swim out of the position between the upper and lower passages, he was too nervous, he couldn't help but breathe hard, and the bubbles he spit out were several times more than normal, and for a time he blocked his vision, and there was chaos around him.

The same was true for everyone else, and it took a long time for everyone to calm down again.

Gao Chao used the diving lamp to look for the people around him, and everyone regrouped, but no one dared to linger for a moment between the upper and lower passages, and they all quickly swam to the side, wanting to study what had just happened.

But as soon as everyone got together, Gao Chao looked around, and his brain buzzed, and he became nervous again.

He danced twice at the crowd, and the others immediately became uneasy, and when they looked around, they were all dumbfounded.

It turned out that they were now reunited, and when everyone looked at the number of people, there was one less, and when they compared with each other, the person who was actually less was the key person in this operation - Lian'er.

There were originally five people, but suddenly there were only four left, but the four of them were not idle, and immediately began to search around.

Although the surrounding environment is dark, there is only such a big place, even if Lian'er wants to hide deliberately, I am afraid it will be difficult to do so.

Gao Chao gritted his teeth and tried his best to calm down, he suddenly remembered that the black shadow passed by them just now, could it be that the black shadow attacked Lian'er?

Don't dare to think about it anymore, don't dare to think about it more, time is life now, if you want to continue this operation, you must save Lian'er.

Thinking of this, Gao Chao immediately desperately swam to the entrance of the passage below, and when he came closer, he found that there was another person next to him, and he took a closer look, it turned out to be Hua Ye.

It seems that Hua Ye also reacted, and Lian'er Bacheng was swept away by the black shadow.

All four of them came to the entrance of the passage, turned on the diving lamp to the brightest, and looked down closely.

However, I found that this passage was roughly hexagonal, at least more than three meters wide and narrow, and it was no problem for people to enter, but it was really too dark, even if it was illuminated by four diving lights, it was still impossible to see ten meters away.

Gao Chao couldn't help but glance at Hua Ye, Hua Ye seemed to understand what he meant, and nodded, in this situation, even if the situation below the passage is too difficult, there is no other way to choose, for the sake of Lian'er's life, only to dive down first.

So Gao Chao gestured to the fat man, and then pointed to Xia Qing beside him, meaning that he should protect Xia Qing and follow behind, but not too closely.

The fat man nodded, and Gao Chaocai made another gesture to Hua Ye, meaning to let him be in front with him, but separate the two sides, and the two people took care of each other and covered each other.

Hua Ye made an "OK" gesture with his hand, and slowly began to dive down the passage.

The passage was about three meters wide, Gao Chao and Hua Ye swam on both sides of the passage, Xia Qing and the fat man followed, and the speed of the four people diving down slowly began to increase.

Gao Chao and Hua Ye are very anxious, Lian'er was taken away by the black shadow like this, who can tell her safety at this time. The situation at the bottom of the sea is no worse than on land, and people are still slow to move underwater, and any sea creature can turn them around.

Suddenly, a string of bubbles floated up from the depths of the passage, and Gao Chao and Hua Ye glanced at each other, this must be the carbon dioxide released from Lian'er's respirator.

Seeing this string of bubbles is like seeing hope, Lian'er must still be alive, she should be down there.

Gao Chao and Hua Ye began to dive down quickly, but found that the bubbles that had been continuous suddenly disappeared.

All four of them began to get nervous, if the bubbles continued, it meant that Lian'er should still be breathing below, but if the bubbles disappeared, it was likely that Lian'er had disengaged from the respirator, or that she was no longer breathing. (To be continued.) )
