After a general look at the surrounding situation, the group leader had a preliminary understanding of the environment under the ice, and he did not rush to expand the reconnaissance range, but found a place near the ice cave, nailed the fixing rope to the ice overhead, and closed the individual aircraft to hang himself under the ice.

The flight time of individual aircraft is limited by fuel, so it is necessary to save as much as possible.

As soon as the leader of the group fixed himself, the warriors who followed him fell out of the hole, and after a curious sweep, he also followed the example of the group leader and hung under the ice.

In this way, the soldiers came down one by one and hung under the ice one by one, even Ye Han and Luo Qi were no exception.

A few minutes later, everyone arrived, and a group of people hung together like jugglers, out of place with their surroundings.

Luo Qi poked the dry vines curiously: "This thing should have nothing to do with aliens." ”

"Why do you say that?" A group leader asked curiously.

Luo Qi said: "Do you still need to ask, it's too fragile, you look at the alien things, which one is afraid of vacuum?" ”

"Not necessarily, right?" One group leader said, "Aren't insect trees afraid of vacuum?" ”

Luo Qiden was annoyed: "That's on Earth, this is Europa, the environment is different!" ”

"Alright, don't talk nonsense." Ye Han adjusted the pillar of light of the tactical lamp to make the light more concentrated, and the beam of light shot into the deep darkness, and there was no edge in sight.

Luo Qi asked softly, "Boss, what should we do?" ”

Ye Han asked: "Group leader, you came down the earliest, did you find danger?" ”

One group leader said, "I didn't find anything except the vines on the top of my head." ”

Ye Han said: "According to this, this place is still safe for the time being, in this way, everyone will work in pairs, spread out with the ice cave as the center, expand the scope of reconnaissance, report immediately if there is a discovery, forget it if you don't find it, everyone will return here to gather in ten minutes, do you understand?" ”

"Understood!" The fighters spoke in unison.

"Let's go!"

The soldiers immediately divided into groups freely, and after determining their respective search directions, they first started the individual aircraft, then retracted the fixed cable, and then flew into the abyss-like darkness, and in a blink of an eye, the figures of the soldiers were engulfed by the darkness, only Ye Han and Luo Qi stayed in place.

Luo Qi's anxious gaze swept around, but in addition to the light of the stars, there was only dead silence and darkness in this place, and it was the kind of silence and darkness that made people murmur in the bottom of their hearts, even if they had experienced countless bloody storms, they would inevitably feel a little anxious and uneasy in their hearts.

After a while, Luo Qi really couldn't stand the atmosphere of this ghost place, so he took the initiative to break the silence: "Boss, can you find enemies in this place?" Isn't it looking in the water? ”

"We'll talk about that later." Ye Han was not in a hurry at all, "Let's find out the nearby environment first." ”

"Then what do we think of the water? Just jump off? Luo Qi asked again.

Power armor is not afraid of water, but the water depth in this hellish place should be thicker than ice, power armor is at most active in shallow depths, and the deep layers can't go at all, if aliens hide under the water, no one can find out if they are exhausted.

Ye Han didn't know this, but the order was the order, and he had to figure out the situation of the space under the ice and say, "Let's take one step at a time......

As soon as he was halfway through his words, a voice suddenly came over the radio: "Captain, four groups of reports, we have come to the end, and there is no way out of the ice wall in front of us." ”

Along with the communication, there is also a short video.

When opened, the screen shows an almost vertical ice wall, which is overgrown with overhanging vines, and the closer you get to the water, the thicker the vines become, and the vines on the surface of the water are several times thicker than a person.

Ye Han always felt that this scene was familiar, but he couldn't remember where he had seen this scene: "So fast? What is the straight-line distance? ”

"Less than three kilometers."

"What about the left and right? It's all this kind of ice wall? ”

"I don't know, everywhere you can see are ice walls!"

"Okay, I got it." Ye Han said, "You two choose a direction, left and right, walk along the ice wall, and report any findings immediately!" ”

"Yes!"

"Six groups of reports, I've also run into an ice wall here!"

"It's the same as the four groups...... In this way, the four groups, the six groups, you all go to the right, and the other groups, after encountering the ice wall, all go to the right, and see if you can meet something different. ”

The soldiers continued to explore the situation of the space under the ice, and Ye Han slowly drew a rough image of the space under the ice according to the data transmitted back by the soldiers, and after a while, he got a broken map.

Although it is still half missing, it can be roughly estimated that there is an irregular space about three kilometers in diameter under the ice.

Ye Han faintly felt that something was wrong, if it was a normal space under the ice, the edge of the space should be gradually submerged into the water, not a straight ice wall like now.

News came back from all directions one after another, and the map of the space under the ice became more and more perfect, and then Ye Han found that the corner of the map gradually extended outward, and there was actually an extra gap in the outer edge of the space that should have been closed!

Ye Han immediately contacted the second group in this direction and asked what the second group had found, and the second group replied that everything was normal.

The second group continued to move forward, and after crossing the narrow gap, the space outside the gap became more and more open, and seemed to be larger than the space inside the gap.

Ye Han immediately ordered the groups to move closer to the gap, and even he himself rushed over with Luo Qi, and the plan to gather in the tenth became a dead letter.

Soon after, Ye Han rushed to the gap and carefully checked the situation here, and found that there was no difference except that the distance between the ice top and the water surface was a little closer.

Ye Han suddenly thought of something, summed up the distance between the ice cave and the gap, as well as the distance between the ice top and the water surface, and calculated carefully, and found that judging from the changes between the water surface and the ice top, the diameter of this sub-ice space should not be less than seventy kilometers, that is to say, the ice walls found in each group are not the edge of the sub-ice space at all.

Ye Han had the intention to take a good look at the entire under-ice space, but the individual aircraft really didn't have such a long endurance, and if he didn't withdraw the people, it would be difficult to say whether the fuel would be enough to fly back.

Ye Han immediately made a decision and ordered each group to return.

As for the reconnaissance of the under-ice space, it is better to leave it to the Jizhou to find a way, he can take people into the under-ice space, and he has done his best.

However, at this time, Ye Han suddenly saw a faint light emitting from the nearby ice wall, and if he looked closely, it turned out that a beam of light was chiseling through the ice wall.

Ye Han was happy now, and said in his heart that this battleship would really choose a place, after this laser penetrated the ice, the exit was just above the water, and the height was no more than ten meters.

Not right, ten meters?
