"Bang!"

After Lu You let go of his hand, the iron prying fell to the ground, making a loud sound, and it was clearly transmitted to the ears of the two through the seawater, the stone did not have the same strength as Lu You, and he tried to come by himself several times, but he was unsuccessful, and he was almost scratched by the gravel in the water, and finally Lu You dragged him over. Pen ~ fun ~ pavilion www.biquge.info

Entering the No. 7 cabin pool, relying on the light on the diving equipment, Lu You and the others could see that the bottom of the pool was covered with a layer of debris, except for stones, there were many other messy things, and they were constantly moving their positions under the action of the current.

The stone that can't even pass through the passage on its own is undoubtedly a burden in the current situation, but Lu You still took him to struggle towards the No. 1 main pool, and the super iron skid has been carried by the stone, which also saves Lu You's physical strength to a certain extent.

The length of the No. 7 tank was only ten meters, but it still took Lu You and the others more than two minutes to swim to the second inlet, and by the time they reached the No. 1 pool, nearly 10 minutes had passed.

Unlike the previous small pools, as soon as Lu You entered the No. 1 pool, he felt a more powerful water pressure, and when his head turned, the light on his head also illuminated the inside of this big iron box clearly.

It can only be described as a mess, and it can even be said to be a garbage pool, with stones and other debris taking up almost a quarter of the space!

Unlike the other pools, at the end of the pool, there was a large machine, presumably for drainage, and on the other side was a tattered iron wall, which was vaguely distinguishable from what was once supposed to be a round pipe, and some barbed wire and the like.

Behind the tattered iron wall was a thick steel gate, halfway closed, but stuck by a man-sized boulder.

Before coming in, Lu You heard Su Nan say that in fact, the ballast pool is not directly connected to the outside world. There is also a filter buffer tank in the middle, but when I left the factory before, when I opened the water inlet valve, the water flow sucked too many stones over, and the buffer pool was directly exploded.

Although he didn't hit the ballast pool in the first place, when he jumped out of the whirlpool just now, he still squeezed the pool, and even without the help of lights, Lu You could see that many cracks burst out on the outer wall of the iron box, and the light vaguely penetrated from the outside.

After pulling the stone in again. Seeing such a scene, the stone was also stunned for a while, and then hurriedly followed Lu You, who was already swimming towards the valve with an iron pry.

The water pressure in the pool is very strong, but it has not been able to affect Lu You, the water is full of rocks, no matter how careful Lu You is, there are also multiple wounds on his body, fortunately there are no sharks here, otherwise Lu You is really not an opponent.

The water pressure at the valve is the strongest. Five meters away, no matter how hard the stone struggled, it couldn't swim up, and even Lu You was a little difficult and slow to move. However, relying on the iron pry, Lu You still climbed over one stick at a time.

The thickness of the gate is more than a palm's width, and the sparse and simple lines outline the fine metal atmosphere of workmanship, although the gate is deformed in many places. But there is no doubt that it has not lost its function, it is only stuck by a stone, as long as the obstruction is removed. Then you can cut off the continuous flow of water.

While observing the gate and the boulder, Lu You was also gesturing to the stone, telling him to hide aside and pay attention to safety.

Time was still passing, and after inspecting it, Lu You grabbed the big iron pry in his hand and poked it towards the boulder!

"Boom!"

Shi never knew how strong Lu You's strength was, but this time he watched from the side, and after seeing the iron pry in Lu You's hand hit the boulder and splash out a spark, he was so shocked that he almost glared out of his eyes!

The sound of the impact of the golden stone was sonorous and powerful, but even if the anti-shock force made Lu You's hand a little numb, the boulder was still firmly stuck in the valve for a long time, and it did not move at all.

Pushed away a little and moved his numb arm, Lu You frowned and thought about it, the bigger reason why he couldn't make the boulder move a little bit just now was not because of the lack of strength, but because of the wrong position.

The shape of the boulder is irregular, but it is still elongated, just like this, it can jam the valve, if you move the direction, it can also pass through the valve, and what Lu You just aimed at was a fulcrum that could pry the boulder to turn, but even if Lu You shot extremely fast and strong, he was still washed away by the powerful water flow when the iron pry approached the boulder.

The first time it didn't work, of course Lu You wouldn't give up so easily, and when the numbness in his arm dissipated, Lu You no longer took the risk like just now this time, but resisted the momentum of the water and forcibly pried the iron against the boulder, intending to try to see if he could pry it up.

At the bottom of the boat, Lu You didn't know how fast the steamer was now, or if the steamer was running out of horsepower and was pulled backwards by the whirlpool, but at least it shouldn't have fallen back into the super big sea bowl.

In a chaotic force, under the strange force of Lu You, which was three times that of ordinary people, the boulder was really pried, but there were still two corners that were each against one side, and under the impetus of the current, it was easy to not loosen at all.

"Boom! Boom! Boom! ”

When Lu You was still working hard, a rhythmic knocking sound attracted Lu You's attention, turned around and looked, sure enough, it was a stone there with a stone beating on the iron wall, and after seeing Lu You looking over, he pointed to the oxygen tube in his mouth, which was already the oxygen tank behind him.

Lu You was stunned for a moment, and then reacted, could it be that there was not enough oxygen?

Before coming in, Sunan and they briefly told Lu You about some precautions, including paying attention to the amount of oxygen, and there was a watch-like thing in his hand, which was the indicator of the oxygen tank, and he only looked down, and Lu You was shocked into a cold sweat.

A whole tank of oxygen can be used for about an hour, if the breathing is stable and emotionally calm, the use time will be longer, and if the amount of exercise is too much, or the breathing is not steady, then the use time will be greatly reduced.

When Lu You and Shi came in, Sunan said like this: "If you can successfully close the valve, you can come out directly from the exit of the No. 1 cabin, we will guard the outside, you knock three times three long and two short as a signal, and we will open the manhole cover." However, if you can't close the valve, be sure to swim back when there is a quarter of the oxygen tank left! If not, there will probably not be enough oxygen to support you leaving!
