A few minutes later, several people had already seen the deep ditch that had suddenly appeared.

It's like a tear zone that suddenly appears in an earthquake, and you can smell fresh earth. Plants, dirt, and even rocks on the surface were torn apart, blocking their planned path.

The ravine could not be seen to the left and right, and the data transmitted by the aerial detector showed that it was not a long straight ravine, but a large fissure, so large that it surrounded the entire mountain in front of it.

It's as if the entire towering mountain suddenly grows a moat. The area inside the "moat" is so large that the "moat" looks like a large straight river, so the naked eye cannot see the bends on either side for the time being.

From the location where Li Sa and the others were, across the ravine, you can see a black hole on the mountainside, the plants on both sides of the black hole are still burning, and the fire is spreading outward. It was as if something burning had crashed into the mountain, straight into the depths of the rock.

The ship that fell did not plunge headlong into the ground, but crashed diagonally into the mountain. It was like a missile with huge thrust going in, and perhaps there was a more violent explosion in the belly of the mountain, but there was no sign of the ship from the hole.

Yao Fei'er's high-altitude detection device could only capture the hot and huge energy, and determined that the spacecraft was in the belly of the mountain, not passing through the mountain, as for whether the spacecraft was still intact or badly damaged, it was impossible to depict it more accurately because the mountain rock barrier heat was unstable.

Yao Fei'er took out some accessories from the space, quickly assembled two small unmanned detection equipment, and released one out, without using people, and went straight to the big hole on the mountainside to drill in. She handed the other one to Li Tianya and said, "You control this one to look down the ravine, I always feel that there is something strange under the ravine." ”

In the barrage in the 369 live broadcast room, the audience couldn't help but speculate when they saw this rare hole and the ravine that seemed to tear automatically:

[Could it be that the ship hit something that caused an earthquake on the planet's surface?] ]

[Earthquakes only crack a few large cracks irregularly, who have you ever seen that can directly crack a large circle and enclose such a tall mountain?] ]

[Perhaps this mountain is not a natural peak, and there are other man-made objects beneath the surface.] The spaceship crashed into it and triggered some traps, so that the surface cracked, and the follow-up may not be peaceful. ]

[The primeval jungle on the surface looks like it's been around for thousands of years, right?] At that time, humanity had already built civilization here? ]

[Probably not human civilization, nor the advance party of immigrants to civilization in space.] Maybe it's a local civilization on this planet that has left behind a creation. Those civilizations have long since disappeared, and natural vegetation and creatures have reoccupied the surface of the earth to become the original planetary form it is today. ]

[I've read some historical documents that in the early years of the interstellar immigration program there were two processes, the exploratory period and the formal immigration period of the establishment.] The exploration period is like a plant planting seeds, projecting thousands of small exploration ships from the home planet to the periphery. Those are one-way, carrying a certain number of human fertilized eggs, and there is no return, and the right planet will be found before landing. ]

[I know this, but at that time, the definition of the planet to be moved to was very vague and very different, and although some spaceships successfully landed manned, the people inside could not leave the spacecraft for life, because the external environment was too harsh.] ]

[Yes, but with the sacrifice of these predecessors, very important data has been passed back, so that the latecomers can be prepared to go and establish a base with more targeted resources and population.] ]

[All of these things have happened in the last millennium, though.] The dense primeval jungle of the host's planet doesn't look like it can be formed in a thousand years, right? ]

[However, have you ever thought that if this planet contains a substance that can speed up the metabolism, not only affecting humans or insects, but also plants?] Most of the plants on this planet are common to us, but they are a little different in size. ]

Li Sa couldn't help but feel moved when he saw this kind of comment. If the vegetation they could see was also brought by the early exploration ships of the interstellar civilization, and the growth was accelerated by some kind of energy released by the planet after sowing, it could indeed cover the entire planet's surface in just a few hundred years.

Where they are, there will be all kinds of strange influences, and there is a basis for this. The high mountain in front of them may not really be a high mountain, a large mound formed in less than a hundred years?

In addition, the reason why insects and beasts invaded this planet may also be caused by human exploration teams. Those insects and beasts also have civilizations and can "immigrate" across the stars, and they may have come here because they thought the ecological environment here was good.

Of course, these thoughts do not solve the problem at hand, they need to cross the ravine first. If you go to the sides of this ravine, there is definitely no way to get in, and high-altitude detection has confirmed this.

Now, in order to be safe when crossing the ravine, they first need to make sure that there is anything strange at the bottom of the ravine.

With their current ability to move, it is not possible to jump more than ten meters directly with their legs for the time being, and to jump over on a mountain motorcycle, then they must use some acceleration slopes or physical principles, and also consider the success rate of accelerating the leap when carrying two weights. However, with Dr. Yao here, it is enough to get these accurate parameters directly by mental arithmetic.

Li Tianya manipulated a small drone to explore the bottom of the ravine, descending a kilometer or two, and still found nothing.

Yao asked Lu Jingjing to collate the data from her upper-air observations, including meteorological data, to more accurately support her calculations. She focused on the information from the probe that flew into the cave to see if they would be allowed to enter without professional protective gear. After the impact, there may be some environment in the cave that is not conducive to human survival.

In addition to paying attention to possible threats around him, Li Sa also approached the ravine and looked down.

The ravines are bottomless, pitch black, and the width of the two sides is not very uniform, about ten meters on average, like a torn wound, not smooth, inside and out, and some plants are pulled and broken, and they are placed on top of the ravine, and it seems that the dexterous player can use these things to land and jump to the other side of the ravine.

She wondered if she should try it first and jumped to the other side. If she can do it, then Li Tianya and Dr. Yao, who are better than her in physical strength, strength and agility, must be fine. The three of them walked over with the budding new Lu Jingjing, it shouldn't be difficult.

Suddenly, several of them heard a strange sound coming from the bottom of the ditch, as if the metal was rubbing a little harsh, or maybe some kind of hard scales were "creaking" against each other, in short, it must be different from the silence just now.

Something strange happened at the bottom of the ditch, and the ravine was slowly stretched wider at a speed visible to the naked eye.

"Is this ravine growing?" Li Sa muttered.

Li Tianya said in frustration: "The unmanned aerial vehicle that detected the bottom of the ditch lost contact about 4,000 meters below, and the last picture taken was that there were many metallic reflective bands on both sides of the crack." ”
