One Thousand Four Hundred and Thirty-Four Pressure Cooker

Ye Han was speechless. This place was a poor choice. If anyone came out of this hole, wouldn't they fall into the water?

Power armor can be amphibious, but individual aircraft cannot. Although this thing is not afraid of water, the temperature is not low when it is working. If it is thrown into the water and soaked, the alternation of hot and cold may directly destroy it.

He immediately shouted on the radio: "Bridge Bridge, this is Ye Han, please reply!"

The radio was silent, without any response.

Luo Qi looked puzzled: "Boss, what's wrong?"

"Nothing!" Ye Han turned around and flew back, "Is there a repeater in the ice cave?"

"Yes!" Luo Qi's heart jumped, "Is the ice layer blocking the signal?"

Ye Han was not in the mood to study why. Hearing this, he quickly bypassed an ice wall and called the bridge again.

"Captain...hiss...Is...hiss...He Lu!" This time there was finally a response, but the noise was a bit loud.

Ye Han continued to fly towards the ice cave: "He Lu, 1.7 kilometers southwest, who dug the hole?"

"It was Yonghe!" Probably because the distance was closer, the communication was much clearer.

"Remind Yonghe, their hole entrance is too low, only ten meters from the water surface, slow down when coming down." Ye Han said.

"Understood!"

"Also, report to the flagship, the situation under the ice is very complicated, and the communication distance is extremely short. For safety reasons, it is recommended that the reconnaissance troops move nearby, and it is best not to leave the communication range, or install repeaters in time."

"Yes!"

After solving the problem of the ice cave, Ye Han shouted on the radio: "Attention, all groups, attention, everyone withdraw immediately, received a reply!"

But the distance of a few kilometers has cut off contact with the warship. If the soldiers fly too far, the possibility of losing contact will be 100%.

"Group 1 received!"

"Group 4 received!"

"Group 6 received..."

After a series of replies,

There was no sound in the radio, and Groups 3, 5, and 9 did not respond.

Ye Han immediately shouted: "Attention, all groups, contact Group 3, Group 5 and Group 9 immediately, and call me back when you get in touch!"

The radio immediately became chaotic, with calls from Group 3, Group 5 and Group 9 mixed together.

A few seconds later, a surprised voice came from the chaotic calls: "Group 5, Group 5, we've got in touch!"

"Group 9, Group 9 has also been contacted!"

"Where's Group 3? Is there any news from Group 3?" Ye Han asked anxiously.

"Yes, Group 3 has news and is on its way back!"

Ye Han let out a long sigh: "You're running pretty fast, hurry back, I'll wait for you at the ice cave!"

"Yes!"

After calling Luo Qi, Ye Han took Luo Qi all the way back to the ice cave. He wanted to find a place to hang himself, but he really didn't like the way of resting while hanging, so he simply flew into the ice cave and used a laser gun to cut a side hole three or five meters above the cave entrance that was big enough for him to live in, and then stayed in the cave and waited for the others to return.

The cut ice blocks were thrown casually, and they slowly fell for hundreds of meters, and finally fell on the sea surface, splashing large pieces of water.

The ice blocks were not big, but the gravity of Europa was low, so the splashes looked particularly large, and the muffled sound of ice blocks hitting the water could be heard faintly.

Luo Qi poked his head at the water surface and said, "Can you still hear the sound of water? This place is not so empty!"

Ye Han sat on the simple ice chair that he had cut casually, leaning against the ice wall and letting out a sigh, "Of course, otherwise the water below would have boiled long ago, how could it be so calm?"

"I should have brought a barometer earlier..."

The two chatted with each other, and no one noticed that a pair of eyes were floating up from the rippling water waves, staring at the conspicuous hole on the bottom of the ice without blinking - other places were "starlight" shining, but only the area near the ice hole was pitch black, and it was hard not to be conspicuous.

At this time, a reconnaissance team flew back from a distance. Two people flew into the ice cave one after another. The blue tail flame left several clear traces on the eyes between the waves.

The team members returned one after another, and the eyes sank cautiously into the water and never floated up again.

The last to return was the third group. As soon as they entered the ice cave, they heard Ye Han's dissatisfied question: "Where did you two go?"

The two soldiers couldn't wait to show their treasures: "Captain, look what we took!" While talking, they sent a video to Ye Han.

Ye Han opened the video, and at the beginning, it was an image of the laser about to drill through the ice layer. The dark ice layer was illuminated by the laser and dimly lit, and the vines attached to the bottom of the ice were eclipsed.

The camera zoomed out, and the laser suddenly penetrated the ice layer. A layer of mist rose instantly on the water surface under the ice. The mist rose from the bottom to the top. The closer to the ice cave, the more obvious it was. When it poured into the ice cave, the mist had become extremely thick, and it was like a tornado spinning into the ice cave.

At the same time, the vines near the ice cave withered at a speed visible to the naked eye, and the dots of light gradually extinguished with the ice cave as the center.

Luo Qi muttered in disappointment: "I thought the entire sea surface could boil!"

Ye Han's mouth twitched, thinking that I thought so too, and it was only after watching this video that I realized that I was wrong before.

He felt that the current situation was like a pressure cooker that had just been removed from the fire. The ice cap was the lid of the pot, and the ocean under the ice was the water in the pot that had just calmed down. Although the water temperature had exceeded the boiling temperature outside, the pressure in the pot increased the boiling point of the water due to the ice cap, so the water surface remained calm.

Ice holes penetrate the ice cap, just like opening a pressure reducing valve on a pot lid, and the air under the ice immediately rushes out under the pressure.

Since the area of ​​the ice cave is very small, if the water surface does not pass through the hole, only a small amount of water surface contacts the vacuum, and the water surface will inevitably boil violently.

But the actual situation is that the space under the ice is huge. It doesn’t matter even if all the air rushes out. As long as the surface of the water surface evaporates a little, the lost pressure can be replenished. Unless the ice cover is completely uncovered, there is a possibility of widespread boiling of the water surface. Extremely small.

Ye Han figured out the joints, but didn't think it was of any use. The environment on Europa was too special. Apart from here, he couldn't think of any other place where he could encounter a similar environment, let alone a place like this. The environment and aliens are at odds.

When everyone arrived, Luo Qi couldn't help but ask: "Boss, has our mission been completed?"

Ye Han thought for a moment and said, "It should be done."

"Then when are we going back? I don't want to stay in this damn place for a minute anymore." Luo Qi said while looking into the cave.

Ye Han said: "I don't want to stay too long, but do you think the flagship might let us evacuate first?"

Luo Qi grinned: "Probably not..."
