One Thousand Nine Hundred and Fifty Whirlpool

The Lone Wolf, which had been silent for many days, suddenly began to adjust its position, and soon moved to the left front of Europa Zero. The edge of the continent was directly below the battleship.

Ye Han mobilized all the remote sensing equipment on the ship and conducted an all-round scan of the target location. He found that the depth of the underwater canyon was much deeper than expected, with a vertical depth of no less than ten kilometers. It was not so much an underwater canyon as it was Rather, it is a trench.

He immediately gave an order to the damage control department, and the 3D printer on the ship immediately began printing pressure hulls for the torpedoes.

A few hours later, the pressure shell was printed and it took a while to install it on the missile. The specially-made missile ejected from the warship and flew quickly towards Europa.

As before, the aliens still did not appear this time. The missile easily fell into the atmosphere and accurately fell into the sea water, successfully releasing the torpedo in the warhead.

The underwater canyon was too narrow. Ye Han had no confidence in the guidance system on the torpedo, so he simply took over the torpedo and manually controlled the torpedo to sink to the bottom of the water.

At the beginning, the picture returned by the torpedo was a sea of ​​blue water, and a few strange-looking alien fish could be seen in the water from time to time. However, after a while, the torpedo penetrated into the canyon, and the surrounding brightness dropped rapidly. After a while, the screen went dark and nothing could be seen on the screen.

But until this time, the torpedo still failed to reach the bottom of the water. Ye Han could only determine the location of the torpedo through the detection equipment on the battleship, and found that there was still a full two-thirds of the distance to the bottom of the water!

After another ten minutes, the torpedo finally hit the bottom. Ye Han took a deep breath and immediately issued the detonation command.

A bright light suddenly exploded under the water more than 10,000 meters deep, and was quickly submerged by the surrounding seawater. The narrow canyon was forcibly opened by the explosion, and violent undercurrents swept in all directions.

The nuclear explosion caused all signals to be interrupted, and the remote sensing equipment on the ship could not detect any data. At this moment, Ye Han could only wait patiently.

A small vortex soon appeared above the target point. At first, this phenomenon did not attract anyone's attention. Everyone just thought it was one of the side effects of the nuclear explosion.

But that inconspicuous whirlpool soon changed. The diameter became larger and larger, the center became deeper and deeper, and the edge even touched the coast. The strong current continued to wash away the rocks on the shore, and the water flow picked up the rocks on the shore. Drag them into the water.

Ye Han suddenly frowned: "Something's wrong!"

He Lu was startled: "Captain,

What's wrong? "

Ye Han pointed to the vortex on the screen: "If this thing was caused by a nuclear bomb, it should have disappeared long ago. But after such a long time, the vortex has not disappeared, but has slowly expanded. Do you think this is normal?"

He Lu immediately realized that something was wrong: "This is abnormal... You mean, there is space under the water?" Although he had not studied advanced knowledge such as fluid mechanics, he still knew the cause of the vortex.

Ye Han nodded: "If I guessed correctly, this vortex appeared because the nuclear explosion penetrated the underground space and caused a large amount of sea water to escape!"

He originally couldn't think of a way, so he decided to give it a try, but he didn't expect that he got unexpected results.

He Lu's eyes shone: "Captain, this thing is hollow. If all the water goes in..."

Ye Han immediately understood: "Print a few more sets of pressure-resistant shells immediately, the sooner the better!"

Regardless of whether the nuclear bomb just blasted through the underground space, this vortex is likely to be a breakthrough to break the deadlock. As long as there is a glimmer of hope, Ye Han is willing to give it a try.

The waiting time was always so long. While paying attention to the printing progress of the pressure shell, Ye Han stared at the whirlpool on the sea, for fear that the whirlpool would disappear in the next second.

It wasn't until the new pressure-resistant shell was printed that Ye Han breathed a sigh of relief and launched the second missile as quickly as possible... After the second torpedo hit the water, it was immediately swept away by the whirlpool and disappeared in the blink of an eye.

The scheduled detonation time of the nuclear bomb was thirty minutes, but after half an hour, there was no movement under the water. Ye Han was both looking forward to it and worried. He didn't know whether he should continue to drop the remaining nuclear bombs.

A few minutes later, a change finally occurred. The stabilized vortex suddenly slowed down, but after a while, the vortex expanded again. Not only did the diameter expand, but the flow rate of the seawater also accelerated a lot.

Witnessing this scene, Ye Han was very hesitant and didn't know whether to continue launching nuclear bombs, but he quickly made up his mind to launch another missile.

He was already certain that the underwater nuclear explosion must have penetrated the underground space. With so much seawater pouring into the cave, aliens must be busy sealing the cave.

Continuing to release nuclear bombs may either widen the crack or block it. However, if we do not release nuclear bombs, it will be a matter of time before aliens block the passage.

Given the lesser of two evils, Ye Han still felt that continuing to blast would be more beneficial to humanity.

In the following period, a nuclear bomb was dropped every half hour, and the vortex also fluctuated several times, but the general trend continued to expand. Only one side of the vortex was blocked by the coast, so the diameter did not continue to expand.

However, the speed of the seawater speeds up again and again, and the seemingly solid coast is crumbling under the impact of the current. The sand and rocks are continuously drawn into the seawater, sinking into the whirlpool and disappearing.

After the last nuclear bomb was thrown into the whirlpool, Ye Han stared at the rotating sea water for a long time, always hesitating whether he should continue.

Judging from the current situation, the nuclear bombs dropped into the sea have indeed achieved unprecedented results, and it is said that we should continue our efforts. However, all nuclear bombs occur underwater, and the actual effect cannot be seen at all. What if the success falls short?

After thinking about it, Ye Han finally decided to observe it for a few days before talking, but only a few hours later, He Lu found Ye Han in a hurry: "Captain, there's something going on!"

Ye Han's heart skipped a beat: "What happened?"

He Lu grinned: "I just compared the satellite data and found that the position of the planetary engine has risen a little..."

"What? How is this possible?" Ye Han didn't believe it at all and stared at He Lu with wide eyes.

There has been no change for such a long time. Why is it rising at this time? Is it possible that the lifting and lowering of the planetary engine is related to seawater? Is it possible that seawater is pouring into the underground space and pushing the planetary engine out?

He Ludao: "We also thought it was unlikely. Then a few of us analyzed it and thought it might be that too much sea water was lost and the sea level dropped a bit..."

Ye Han couldn't believe his ears: "Is there something wrong with you guys? With such a big planet and such a big sea surface, how much sea water will the sea level drop by one centimeter? Can it be measured in just a few hours? Do you believe it? "
