In order to speed up the progress, Ye Han not only sent all the marines on the ship, but also mobilized a part of the crew, and more than 100 people in front and behind were all sent into the ice cave.

There was not much space in the ice cave, but there were not so many places to stay, so the warriors could only fix a foothold and get in a few people until everyone entered.

When everyone entered the ice cave, it was already overcrowded between 7.4 kilometers and 7.5 kilometers, the soldiers were attached to the cave wall, the laser beam flew back and forth, and the pieces of broken ice were cut off the cave wall by the laser, and the soldiers threw them down the ice cave, and the poor drone didn't know which piece it was hit, and it had long been turned into useless scrap metal.

But it doesn't matter, it's just a drone, and it's nothing compared to the mission.

More than 100 people worked for two hours to repair the passage more than 100 meters long, and the broken ice thrown into the ice cave alone filled the bottom of the cave with more than 400 meters.

But this is not the end, after repairing the ten by one hundred meters ice cave, the soldiers still could not stop, the upper ninety meters were left alone, digging deep to the side in the bottom ten meters, spending several hours, digging out a huge space under the ice, and finally pulling out ten cylindrical icicles with a diameter of ten meters and a height of ten meters here.

By this time, the crushed ice thrown into the depths of the ice cave had been clogged for two kilometers.

At this point, the project seemed to be over, but in fact it was only half completed, and after ordering all the soldiers to enter the side cave and no one to approach the main cave, the Thunder Mountain fired at the first hole again, and the laser penetrated straight into the first hole, melting the broken ice accumulated at the bottom of the hole.

The warriors in the side cave first saw a beam of light penetrate the main cave with unerring accuracy, and then a strong steam rushed out of the bottom of the cave, and the air flow was blocked by the change of direction, and finally formed a whirlwind in this section of ten by one hundred meters, and the whistling wind was like a rush, and the scene was a shock.

However, the laser only lasted for a short time, and then stopped after removing the ice from the bottom of the cave.

But when the soldiers left the side hole, they found that the 10 by 100 meters section had been deformed by steam, and many places that should have been right angles had been rounded.

I didn't say it, fix it, so the fighters spent another half an hour repairing it again, and it was not finished until all the positions were up to standard.

Finally everything was ready, Ye Han and all the people who were concerned about the progress of the project were relieved, and most of the more than a hundred people evacuated the ice cave, leaving only a combat group on standby.

Before the evacuation, the communication group also deliberately installed several repeaters in order to continue to maintain contact with the warship after blocking the ice cave.

Cave No. 1 of the Leishan is the first ice cave to complete the preparation of the project, and the ice caves of other ships are still under construction and are expected to be completed in three to five hours.

At this time, the belated international fleet finally arrived at Europa, and after Halsey and Jizhou contacted him, he found out what the Chinese side was busy with.

Halsey insisted that the aliens must be hiding under the ice, not under some hellish water, and that there was no need for the Chinese to penetrate the ice, let alone scout the ocean under the ice.

Huo Qiang bluntly said that I wanted to do this, but I really couldn't find the enemy in the ice, so I had to make this decision!

As the saying goes, different ways do not conspire with each other, but the two fleets have different viewpoints, but they must cooperate sincerely, and in the end, no one can convince anyone, so they simply do their own thing, the Chinese side continues to dig the ice, and the international fleet continues to share China's unfinished business, and continues to look for a needle in a haystack in the ice to find the shadow of aliens.

After the unpleasant communication ended, Huo Qiang issued an action order to the Thunder Mountain, and for the sake of safety, Huo Qiang asked Ye Han to make comprehensive preparations, preferably commanded by Ye Han himself.

Ye Han was helpless, Huo Qiang's tone was discussed, but could he take this as a discussion?

He could only take all the equipment and return to the ice cave with the Marines who had just withdrawn from the ice cave, and after entering the side cave at 7.5 kilometers, he gave the order to start the operation.

The laser fell into Ice Cave No. 1 for the third time, and the ice at the bottom of the cave quickly melted, and the steam rushed into the sky again.

Ye Han didn't know how long it would take for Cave No. 1 to be opened, but judging from the situation of Cave No. 2, the remaining ice layer was not much thicker.

Only two minutes later, the sound of the wind outside the cave suddenly became several times faster, and the originally scattered ice feathers could only be regarded as light snow, but in the blink of an eye, it turned into goose feather heavy snow.

Luo Qi immediately reminded: "Boss, it's through!" ”

Ye Han said: "Got it, a group, on!" ”

The group that had been on standby at the entrance of the cave for a long time immediately pushed the icicles, but the air flow outside was too strong, and the steam continued to drum into the side holes, coupled with the weight of the icicles themselves, the warriors were unable to push at all.

"Two more sets!" Ye Han ordered loudly, and two more battle groups rushed forward, and more than 20 people worked together to finally push the icicle and move it towards the ice cave little by little.

However, after the icicles were pushed to the main hole, they were resisted by the pressure from the outside, and they could no longer push the main hole after only half of it was plugged in half, no matter how many people were on it.

Luo Qi suddenly said: "Boss, the pressure on the outside is high, and the pressure on the inside is small, this is not a matter, should we also open up the inside with the bottom, so that the balance between the inside and outside is easy to push." ”

Ye Han nodded immediately: "Just do it." ”

Luo Qi immediately called a combat group, and after two orders, the entire group took out their laser guns, found a corner that was out of the way, and fired diagonally downward.

The laser melted the ice, and soon made a small hole that led to the main hole, and a blast of wind erupted from the hole.

The warriors continued to expand the hole, and in a short time, the small hole the thickness of their fingers became the size of a bucket, and the internal and external air pressure quickly neutralized, and finally they were able to push the icicles again.

After a few minutes, the icicles finally blocked the main hole, because the size of the hole was strictly controlled when digging, although the gap between the icicles and the main hole was not tight, but there was not much gap, and the heavy icicles slammed upwards under the strong air current, slamming above, blocking the main hole like a piston.

The violent air flow immediately weakened by half, and the ice feathers that had risen rapidly slowly fell like snowflakes.

"That's it!" Ye Han showed a smile: "Quick, fix the icicle and release the drone!" ”

The fighters sprang into action, and several combat groups dedicated to the icicles pushed the second icicle out.

The second icicle was in place, blocking the air flow from below, and the icicle that was originally on top of it actually trembled and descended, and the already gentle air flow rose again, and actually pushed the second icicle up, and the two icicles collided together in the air, and then pressed together, and finally slowly rose to the top.
