The wolf cub's mind reached into the virtual bridge and called up all the numbers related to the cave.

The cave was formed at an unknown time, but it was extremely long and the space inside was huge, and in addition to the entrance that the wolf cub had found himself, there was a large half-buried hole on the other side of the mountain.

The wolf cub carefully marked the symmetrical part of the cave, and soon, something that ran through most of the cave took shape under his description, although the part marked by the wolf cub was not complete, but only the existing part, everyone still saw some clues.

"It's like ...... A spaceship? Ye Fei exclaimed in disbelief, his eyes full of surprise.

The shape on the screen is the outline of a spaceship.

"As you can see." The wolf cub said with a sigh.

Even he didn't expect that comparing the lines in the cave according to the lines on the mural would be like this.

"This is the secret that the mountain people hide in the mountains?" Ye Fei took two breaths of cold air, and suddenly his eyes widened, "No, wolf cub, how did you see it?" Didn't you already know that? ”

"Haha......" the wolf cub said with a smile.

"Be strict, don't smile with me." Ye Fei was angry: "I don't want to think about it, right?" Dare to sell it to me! ”

At this time, he also found that the situation of this cave was not quite right, the drone did not have the ability to distinguish small animals, and when it scanned these small things, it would treat them as part of the cave itself, and realistically restore them to the digital model.

It is said that such a cave should be very humid and inhabited by many cave creatures. But there was nothing on the digital model, and the cave was as clean as the surface of the earth that was exposed to the sun every day.

This situation is by no means normal.

The wolf cub quickly put away his smile: "What, chief, I really don't know anything, but I suddenly feel that those stones are familiar." ”

The black bear suddenly said: "It looks quite similar, but is it not a real spaceship, is it not necessary to go down again?" ”

"No, you don't." Ye Fei waved his hand and said, "Xiao Xia, has this place been swept over?" ”

Xia Zhuoyan hurriedly replied: "I have swept it, but the cliff is too high." Radar waves can't penetrate it. ”

Electromagnetic waves can't travel far through the earth. The best way to find a target deep underground is to detonate a nuclear bomb and artificially create a low-intensity earthquake.

"Looks like we're going to have to go down." Ye Fei said funny, "Old bear." You control the assault ship. The wolf cub went down with me. Start preparing now. ”

If it was replaced by other warships, perhaps the officers on the bridge would be in an uproar and persuade the captain not to leave. But this will never happen on Ye Fei's battleship, everyone is used to his problem of not playing cards according to the rules.

"Why did you let me stay?" The black bear muttered discontentedly.

The new assault ship can be remotely controlled in the Xinyuan or inside the assault ship, but in either case, it must be retained. But he really wanted to go into the cave to take a look, if it was really the battleship of the ancestors of the mountain clan, he hadn't entered the battleship of an extraterrestrial civilization yet-the outer bone people didn't count!

"Why else is it that you're too big!" Scissors grinned and teased.

"Scissors is right, this hole is not for you." Ye Fei said.

The inside of the cave is spacious, but the entrance is very narrow, the black bear's figure is originally arrogant, and after putting on the combat armor, it is even more five big and three thick, and the work of digging holes is really not suitable for him.

The black bear didn't know that there was a bigger entrance on the other side of the cave, so he could only reluctantly accept the sad reality, leave the bridge with Ye Fei's wolf cub, and parachute in combat armor.

A few minutes later, Assault Ship No. 1 separated from the Xinyuan again, plunged headlong into the atmosphere of Rennu, and fell with a full of light and flames towards the mysterious tribe hidden deep in the mountains.

The mountain tribesmen who had just returned to the tribe saw the assault ship that had gone and returned, and when they landed, they turned into birds and beasts.

The black bear smacked his lips: "It's quite fast." ”

"Can you not be happy?" Ye Fei joked, "Life and death, this is forcing all the potential out." ”

"Funny, what do I want their lives for?" The black bear pouted disdainfully.

Bullying the Shang clan is very fulfilling, and the feeling of cleaning up the mountain clan is not much different from abusing small animals, and it is completely meaningless.

The assault ship was suspended above the cliff, Ye Fei and the wolf cub only carried rifles, flew down from the assault ship lightly, and landed lightly like feathers, first releasing a drone, and then the two of them carried rifles and followed the drone into the cave one after the other.

It is impossible for the mountain people to cause damage to the battle armor, but the light in the stone house is terrifying, and no one dares to say that there is no danger in the cave, and there is nothing wrong with being careful.

The terrain in the cave is tortuous and rugged, and the two of them are slowly moving forward under the guidance of the drone, and the murals are displayed in front of the two of them, but the two of them are not studying archaeology, so they can't see any value of these murals at all, so they directly ignore the past and move towards the depths of the cave.

Many parts of the cave were so cramped that the two of them had to squeeze sideways, or even crawl on the ground, but fortunately the auxiliary power system was strong enough to not get stuck in the cave wall.

After walking more than 300 meters cautiously, his eyes finally opened up.

Ye Fei glanced at the number recorded along the way: "The straight-line distance between here and the entrance of the cave is about two hundred meters, right?" ”

"Almost." The wolf cub said, "It's a real trouble to have the communication cut off. ”

More than thirty meters after entering the cave, the communication between the two and the assault ship was interrupted.

"That place is just ahead, isn't it?" Ye Fei saw the mural on the wall of the cave that represented the spaceship, and immediately gave a command to the drone in front, and the drone immediately turned on the lights, and the snowy light illuminated the front brightly.

Directly in front of the two of them is the first place where the wolf cub found that something is wrong, and at a glance, the first thing they see is a flat round bulge like a grave bag, and there are two symmetrical stalagmites pointing obliquely on the left and right.

Up close, the bulges and stalagmites are covered with patches of mottled crusts, but from a distance, they are very precisely shaped circles.

The wolf cub couldn't help but praise, "I'm more convinced that this thing is a spaceship now." So saying, he stepped on the uneven ground, knocked on the stalagmite, and was surprised to find that it was a real stone, and then leaned on the bulging edge of the stone wrap and struck it twice with all his strength, and finally smashed down a stone the size of a palm.

"Isn't it? Is it really my delusion? The wolf cub couldn't hide his disappointment and couldn't help but look deeper into the hole.

Ye Fei suddenly made the wolf cub laugh: "You just knock twice like this, what can you see?" As he spoke, he walked over to the drum and pressed one hand on the stone skin to activate the sound wave detection system, and an invisible ultrasound wave quickly spread out in the bulge.
