Ye Han was speechless for a while, there is no one to choose in this place, if anyone comes out of this hole, won't they be planted in the water?

Power armor can be amphibious, but individual aircraft can't, although this thing is not afraid of water, but the temperature is not low when working, throw it into the water to soak it, hot and cold alternately, and if you don't do it, it will be scrapped directly.

He immediately shouted on the radio: "Ship Bridge Ship Bridge, I am Ye Han, please answer if you receive it!" ”

There was silence on the radio, not a single echo.

Luo Qi's face was inexplicable: "Boss, what's wrong?" ”

"It's fine!" Ye Han turned his head and flew back, "Is there a repeater left in the ice cave?" ”

"Stay!" Luo Qi's heart jumped, "Is the ice blocking the signal?" ”

Ye Han was not in the mood to study why, and when he heard this, he quickly bypassed a wall of ice and called the bridge again.

"Ship ...... Long...... Wow...... I...... Wow...... Ho 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, one point and seven kilometers to the southwest, who made the hole?" ”

"It's the Yonghe!" Probably because the distance is closer, the communication is much clearer.

"Remind the Yonghe that their hole is too low, only ten meters above the water, slow down when you come down." Ye Han said.

"Understood!"

"Also, report to the flagship that the situation under the ice is very complicated, the communication distance is extremely short, and for the sake of safety, it is recommended that the reconnaissance unit move nearby, and it is better not to leave the communication range, or to place repeaters in time."

"Yes!"

Solving the problem of the ice cave, Ye Han shouted on the radio: "Attention to all groups, attention to all groups, everyone will withdraw immediately, and the reply received!" ”

However, a distance of a few kilometers was cut off from the battleship, and if the fighters flew too far, the probability of losing contact would be 100%.

"A group received!"

"Four groups received!"

"Six groups received ......"

After a series of replies, there was no sound on the radio, and groups three, five, and nine did not respond.

Ye Han immediately shouted: "Attention to each group, immediately contact the third, fifth and ninth groups, and give me a reply when you get in touch!" ”

There was immediately a mess on the radio, some calling three groups, some calling five groups and nine groups, and the calls from all directions were mixed together.

A few seconds later, a voice of surprise came from the chaotic call: "Five groups of five, five groups are connected!" ”

"Nine groups, nine groups are also connected!"

"What about the three groups? Is there any news for the three groups? Ye Han asked anxiously.

"Yes, the three groups have news and are heading back!"

Ye Han let out a sigh: "It's quite fast, hurry up and retreat, I'll wait for you in the ice cave!" ”

"Yes!"

Greeting 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 it and hung to rest, so he simply flew directly into the ice cave, used a laser gun to cut a side hole that was enough to accommodate himself at a height of three or five meters above the entrance of the cave, and nested in the hole and waited for others to return.

The cut ice is thrown casually, and it slowly falls for hundreds of meters, eventually falling to the surface of the sea, splashing a large area of water.

The ice is not large, but Europa's gravitational pull is low, so the splash looks very large, and you can faintly hear the muffled sound of ice falling into the water.

Luo Qi probed his head and looked at the water: "Can you still hear the sound of water?" It's not that empty! ”

Ye Han sat on the simple ice chair cut out casually, leaned his back against the ice wall and let out a sigh: "Definitely, otherwise the water below would have boiled a long time ago, how could it be so calm?" ”

"If only I knew I had a barometer......

The two of them chatted word by word, and no one noticed that a pair of eyes were floating on the surface from between the rippling waves, staring at the conspicuous hole in the bottom of the ice without blinking—the "starlight" was shining elsewhere, but it was pitch black near the ice cave, and it was difficult to think of not being conspicuous.

At this time, a reconnaissance group flew back in the distance, and the two of them flew into the ice cave one after the other, and the cyan tail flame left a few clear marks on the eyes between the water waves.

The team members returned one after another, and those eyes sank cautiously under the water, never to rise again.

The last to return was the three groups, and as soon as they got into the ice cave, they heard Ye Han ask dissatisfiedly: "Where did you two go?" ”

The two warriors couldn't wait to present the treasure: "Captain, look what we have photographed!" As he spoke, he sent a video to Ye Han.

Ye Han opened the video, and at the beginning, it was the image of the laser about to chisel through the ice, the dark ice was faintly illuminated by the laser, and the vines attached to the bottom of the ice were eclipsed.

The camera zooms out, the laser suddenly penetrates the ice, and a layer of fog rises on the water surface under the ice instantly, the fog is from the bottom to the top, the closer you get to the ice cave, the more obvious it is, and when it is poured into the ice cave, the fog has become extremely thick, like a tornado spinning into the ice cave.

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

Luo Qi muttered in disappointment: "I thought the entire sea could be boiled!" ”

The corners of Ye Han's mouth twitched, and he said in his heart I think so too, that is, when I saw this video, I knew that I had thought badly before.

He felt that the current situation was like a pressure cooker that had just been removed from the fire, the ice lid 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 of the outside world, but it was bound by the ice cover, and the pressure in the pot raised the boiling point of the water, so the water surface remained calm all the time.

The ice cave runs through the ice cap, just like the pressure reducing valve on the lid of a pot, and the air under the ice is immediately rushed out under the pressure.

Due to the small size of the ice cave, if the water surface does not pass through the hole, the water surface will only touch the vacuum by a small amount, and the water surface will inevitably boil violently.

But the reality is that the space under the ice is huge, even if all the air is washed out, it doesn't matter, as long as the surface of the water surface evaporates a little, the lost pressure can be replaced, unless the ice sheet is completely uncovered, the possibility of a large area of boiling on the water surface is extremely small.

Ye Han figured out the joints, but he didn't think it was useful, Europa's environment was too special, except for here, he couldn't think of any other place where he could encounter a similar environment, let alone fight aliens in this environment.

Everyone arrived, and Luo Qi couldn't help but ask, "Boss, our mission is complete, right?" ”

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

"And when are we going back? I don't want to stay in this place for a minute. Luo Qi said as he looked into the cave.

Ye Han said: "I don't want to stay longer, but do you think the flagship may let us withdraw first?" ”

Luo Qi grinned: "It shouldn't be......"
