Xijiang looked at the dark tomb around him, and an extreme fear invaded him, and he said in his heart, would he really be trapped here and die?

The more he thought about Xijiang, the more scared he became, and he was really afraid, not nervous or anxious, he immediately had a thought at that time, that is, he couldn't die here, if he wanted to die, he should die somewhere else, and at that moment he almost wanted to jump headlong into that inlet and drown himself.

However, Xijiang is an old Jianghu in the end, and his fear was quickly suppressed, he slapped himself in the face, scolded for nothing, and calmed down and began to think about what to do.

Qiu Yan spat out a few swear words, and at the same time looked around for something that could help. Because there was no oxygen at all, he could only pin his hopes on finding oxygen cylinders, so all his thoughts were quickly attracted by the amount of oxygen that was there. He first began to consider whether there was a slight possibility that this little oxygen would be able to survive outside.

In fact, it is impossible to have results, because there is too little oxygen, although when I came in just now, I have been very cautious, and the speed is not fast, if I go out a little faster, it can shorten the time for a long time, but when I came in, I used four parts of oxygen, and now I have to use one part when I go out, that is, the speed of going out must be four times that of coming in.

When you come in, it's about 30 minutes, but when you get out, it takes 5 minutes? According to the calculation of five minutes, where can you reach in those five minutes, it will take about two minutes to get out from here, and you can only reach the exit of the huge abyss in five minutes, which is already the fastest speed.

Once you enter the exit of the abyss, then it will only take about ten minutes, and you will definitely be able to get out, that is, half an hour away, if you are lucky, the two of you can walk in ten minutes, and Qiu Yan looked at the time, the tide is about to ebb, and when the time comes, the entrance of the cave will be exposed to the sea, and a little air will enter the top of the cave, so that you may not have to go to the entrance of the cave to breathe air.

Then you can hold your breath for two minutes, as long as you can get another ten minutes of oxygen.

However, where to find oxygen for these ten minutes? Also, after all, Xijiang is old, and his physical strength must not be comparable to his own, whether he can make it to the entrance of the cave is still one thing, but there is no way here, Qiu Yan scratched his ears and cheeks, and reflexively looked everywhere, hoping to see something that inspired him.

However, what inspiration will there be in the ancient tomb, is it too funny to use the spirit vessel as an oxygen cylinder, this is still the same as thinking in vain, Qiu Yan slapped the water surface of the entrance in annoyance. Suddenly, he saw his own reflection in the dark sea below, he deflected the glow stick, the reflection became clear, he suddenly pursed the corners of his mouth, and there was a bold idea in his head, as if he had found something that would provide him with oxygen for ten minutes.

Qiu Yan was really whimsical, what he saw from the shadow of the water was the diving suit on his body.

So how can the diving suit be used as an oxygen tank? Qiu Yan thought very cleverly, he tied up the sleeves and trouser tubes of the diving suit, and then punched it hard to fill the air inside, and then tied the neckline as well, and the diving suit became an air bag. When he jumped into the water, he unfastened one of his sleeves and used it as an oxygen tube.

Under Xijiang's stunned gaze, Qiu Yan turned over and plunged underwater, and as soon as he went down, he found that it really worked, and he inhaled it for about three or four minutes before he felt that the air was turbid.

He was ecstatic, and immediately poured out of the water and shouted towards Xijiang. "Take off, take off your clothes. ”

Xijiang's character is not the kind of person who is indecisive, and he will not choose a conservative way, so he saw Qiu Yan's self-made 'oxygen tank' at that time with almost no hesitation, and patted his thigh and said excitedly. "Liang boy, you really have you!"

Xijiang quickly took off his clothes, made another airbag, and finally returned to the sea with Qiu Yan with a nervous mood. As Qiu Yan expected, five minutes later, the two of them had already entered the abyss. There was even a little bit of oxygen cylinder.

Qiu Yan's heart had settled down at this time, and he made a few gestures with Xijiang in the water, and he dragged the two huge air bags behind him with great difficulty, and he involuntarily floated up, which also saved him a lot of strength. With his memory, Qiu Yan swam towards the exit of this abyss. However, what he didn't expect was that when they swam to the entrance position he thought they wanted, Qiu Yan was stunned.

There was nothing there, just a patch of jagged coral reef rocks. Further to the side, I shone a lot along the way, but I didn't see the exit.

Qiu Yan panicked all of a sudden, things didn't go as smoothly as he thought, it seemed that he had misremembered the location of the entrance! As soon as he was nervous, he went to look at the oxygen meter, only to see that the index of the oxygen meter was already below zero. But he knew that he must not be nervous at this time, so he untied the oxygen cylinder on his body, kicked it away, and then made a gesture to Xijiang, picked up the diving airbag behind him, and continued to look for the entrance.

In fact, at this time, things were already very bad, when Qiu Yan used a searchlight with little power to shine around, he found that all around was a deep darkness, and he couldn't even figure out the direction when he came.

I couldn't help but blame myself for thinking too naïvely, and a heartbeat that was more violent than the fear of being trapped in the ancient tomb began to appear. That's when he realized that he might really be dead this time.

The corners of Qiu Yan's mouth outlined a trace of arc, I don't know whether to smile or laugh at myself. I don't know why, when people are faced with an unknown desperate situation, they will think wildly, some strange thoughts are ready to move, when the grief and helplessness reach the extreme, there is a cruel self-deprecation that doesn't care about anything. The cold and colorless dark sea, the collision between the air pressure around his body and the skin of the waterline seemed to make his heart sink gradually.
