Of course, Tang Shengxian was not dead, the moment he heard the explosion, he directly retracted the jetpack, and a fully enclosed diving suit was put on his body with the automatic change function of the space. Seven or eight layers of steel plates are directly spliced into a hollow hexahedron, which firmly protects Tang Shengxian inside.

The sky-high flames jumped up more than 700 meters from the bottom, enveloping Tang Shengxian, and he came and retreated quickly, but then there was the sound of the reinforced concrete around the elevator shaft cracking, and the icy sea water rushed in frantically along these cracks. It took less than a minute to fill the thousand-metered passage.

Tang Shengxian also saw the process of the sea water submerging his whole body from the observation hole on his helmet, and the water pressure at a depth of a hundred meters was no problem for him, but at this moment it had fallen into absolute silence, only the occasional sound of concrete blocks falling.

There was no light source, it was pitch black, and at this moment Tang Shengxian was like being in a legendary ocean tomb, and the sunlight could not penetrate the sea water more than a hundred meters deep.

It's a pity that Tang Shengxian didn't have time to sigh about this, he was now stuck in this elevator shaft, the passages above and below were all blocked by concrete blocks mixed with steel bars with two finger thickness, and the protective structure of the regular hexahedral steel plate made by Tang Shengxian was under pressure from up and down, left and right, from all directions, if it weren't for its protection, Tang Shengxian would have been crushed into a meatloaf long ago.

Tang Shengxian doesn't have to worry about oxygen, although the difficulty of eating and drinking Lazar is a bit big, but it can also be done in a deep diving suit, and there is no danger to his life for the time being, but he can't go on like this forever, at this moment Tang Shengxian is studying the map that the system gave him.

I have to say that the system must be a high-quality product. This picture should not have been like this, but under the modification of the system, Tang Shengxian saw the hope of life, and the elevator shaft was built under Hongming Island. Due to the implementation of the dredging project, Hongming Island has been turned into a deep port on all sides, which is different from the continental shelf that extends directly up.

At this moment, it takes a distance of 100 meters to reach the exit, but to the east, you only need to open a distance of 54 meters to enter the sea, and from here it continues to the surface.

The east, west, north, south and north sides are the thinnest in the east, and it was decided so happily that there were still some guys in his hands. A Viodin VOD-G66 underwater cutting gun appeared in Tang Shengxian's hands, but he didn't expect the decision to buy a batch of underwater special equipment so wisely.

Feeling the pressure on the steel plate up and down, Tang Shengxian began to remove the steel plate inside layer by layer, the space he could move in it became larger, and when he drew the penultimate layer of steel plate, he heard the "click" sound of the steel plate, and quickly added the third layer of steel plate back, the third layer of steel plate should be the most suitable thickness, and opened the hollow opening and closing window on the east steel plate, which was designed by Tang Shengxian himself.

Observing the outside from the opening and closing windows. After the movable gravel was retracted into the space, the three steel plates were directly blocked on it, which was to prevent the gravel from continuing to fall.

The cutting head stretched out from the middle opening and closing window, pressed the switch, and made the cutting piece rotate rapidly, aiming at the original ecological rock wall that was completely exposed.

There is no smoke and dust in underwater cutting, only muddy water, and the searchlight on the helmet cannot penetrate the muddy water. It was a lonely and long process, and the space here was too small, which made Tang Shengxian's cutting efficiency very low.

First, use a cutting torch to cut the rocks into small squares one by one. Then use a hammer and chisel to knock it down from the gap cut out, the resistance of the water is very large, and the problem of narrow space Tang Shengxian can't make it out.

It's all going on. In this kind of place, which may collapse at any time, Tang Shengxian will not use explosives to death, although he has also learned underwater blasting skills, and if he wants to use them, he must be stabilized inside.

Retracting the tenth batch of cut gravel into the space, Tang Shengxian had already advanced fifty centimeters, and an hour had passed. The inside of the diving suit is very stuffy, even if you sweat it, the sage will get all the sweat away.

But Tang Shengxian's heart was not too irritable. To be honest, he still enjoys the process a little, in addition to the danger to his life, which is the same as when he was a child, making models alone and playing puzzles of two or three meters by himself. It is a long and serious process, which can wash away impetuousness, calm the mind, and hone patience.

I have to say that Tang Shengxian has the potential to become an otaku since he was a child, he doesn't like to play with other children outside, he neither does he be a child's head nor a follower, he is a maverick and plays his own game.

Such Tang Shengxian has neither developed good leadership skills nor slippery life skills, but he has also developed his own advantages, and he can go further than others on the road of opening up the plane.

Without resting, continue cutting, because of the overload of the cutting operation, the cutting blade of the electric cutting gun has been changed three times. He still has a lot of chips, and as long as he still has the strength, he will keep cutting.

This 54-meter-long tunnel was divided into three stages by Tang Shengxian, the first stage is the expansion, cleaning and reinforcement work that is now underway, and Tang Shengxian can sacrifice a big killing weapon at a distance of one meter.

The east side of the previous hexahedron has been demolished by Tang Shengxian, and after reinforcing the connections on all sides, Tang Shengxian has extended his metal tunnel forward by about one meter and a half, which is almost the same, although Tang Shengxian has now used this model of underwater cutting gun very slippery, but it is very necessary to change to a faster tunneling method.

Put the previous laser cutting machine out entirely, the space that has just been expanded suddenly becomes extremely narrow, I have to say that the base attaches great importance to these machinery, or because of military supplies, this thing was found to be waterproof after Tang Shengxian read the operation manual, and Tang Shengxian didn't know how much it was to prevent it, and there were a lot of waterproof bags on the main body, so he left the laser launch gun outside.

There is no need to worry about the effect of water on the laser, in which the polarization regulator controlled by the smart chip will not let the laser refract in the water, just like the haze cannot affect the accuracy of space-based laser weapons.

The direct cutting depth of twenty centimeters is more efficient than the cutting spear slowly advancing centimeter by centimeter, I don't know how many times, and the tilt angle Tang Shengxian cut one cone-shaped stone after another, so that he can cut the stone without even using a hammer.

It took the same amount of time for the laser cutter to advance the metal tunnel by fifteen meters at once, ten times that of the one and a half meters just now, but Tang Shengxian would not be satisfied with this, and immediately entered the third stage - the rapid bombing and tunneling stage.

At this time, there are only 37.5 meters left, and the rock layer at this time is not as hard as it is inside, and the more the stone is squeezed inside, the greater its mass and density, and the outer layer of rock is a little loose in comparison.

At this time, the most correct choice is to blast, yes, Tang Shengxian wants to play blasting, in order to prevent the collapse of the back, Tang Shengxian has blocked all the tunnels seven meters behind with steel plates, and also cut a two-person sized cave above the blockage, which is opened up to avoid the impact of the blasting, and it also shows the feasibility of Tang Shengxian's plan.

This time, instead of the familiar T, N, T, and C, we bought a liquid and explosive that is suitable for underwater blasting, and has the characteristics of high detonation rate, high power, odorless, non-toxic, non-irritating, non-volatile, specific gravity, pumpable, and soluble in water (easy to dispose of if it does not explode or residual charge).

After inserting the tank containing liquid and explosives into a hole cut in the rock wall, and activating the timing device, Tang Sung-hyun quickly retreated and stacked a large number of thick metal plates in the tunnel, although the direction of the explosion was set on the side of the rock wall, it was better to be cautious.

After doing all this, Tang Shengxian hid in the previous "bomb shelter", he was waiting for the explosion to come.

"heng~meng~" The sound of suppressed deformation finally sounded, and the water around him seemed to be boiling, feeling the impact that was even stronger than just now, Tang Shengxian closed his eyes.

Removing all the steel plates blocking the road, Tang Shengxian came to the place where the explosion occurred, the originally smooth stone wall turned into fine broken stones, while recovering these broken stones, while reinforcing the surrounding structure, the more you go to the back, the bigger the stone is, this time it directly advanced twenty meters, Tang Shengxian's purpose is to shatter the whole stone into small pieces piled together.

The biggest role of explosives in this operation is not how big a hole is blown up or how thick a target is blown through, but how many cracks are created and how far they can be extended.

Ten minutes of preparation is worth five or six hours of hard work, and you still have to rely on wisdom!

The same blast was carried out again, this time directly blasting through the outermost rock wall, Tang Shengxian finally came outside, surrounded by the boundless sea water Tang Shengxian did not panic, all he had in his heart was the joy of rebirth,

An underwater thruster appeared directly in Tang Shengxian's hand, and after it was activated, the thruster pulled the exhausted Tang Shengxian upwards and headed to a place where the sun was shining. (To be continued.) )
