On the southern coastline of the Big Dipper, at the foot of an inconspicuous hill, a huge tent was erected, and ten people in expedition suits were in front of a holographic map.

These ten people are Lin Fei, the disemboweling girl, and the eight hired space mercenaries, a team of interstellar explorers who are very famous in the exploration world.

Although there are only eight people in this team, six men and two women, each of them is a master among the masters in the exploration and excavation of the ruins, as for the real ability, Lin Fei doesn't know, but I heard that the disemboweling girl spent a lot of money to hire them this time.

Lin Fei listened to these so-called professionals explain the preparations and precautions before entering the underground cave, and felt bored. However, the disembowelment girl listened very carefully, and took some notes from time to time.

Subsequently, Lin Fei wore the combat uniform prepared by the ripper, holding an energy gun, a metal dagger, a high-intensity light on his head, a rope and a high-energy food bag hanging from his waist, and a small metal box with an ellipsoid containing medical instruments on his back.

Lin Fei and the disemboweling girl, as well as eight mercenaries who were fully armed and also holding various weapons and expedition equipment, came to a cave at the foot of the mountain.

It is more vivid than a sinkhole, a large circular hole with a diameter of more than one meter, appearing on the ground below the mountain.

Listen to the introduction of the disemboweling girl, this big sinkhole, the reason for the appearance may be the recent submarine volcanic eruption, the underground activity is violent, according to the preliminary exploration of the small robot, this is a huge depth like a labyrinth of underground caves.

However, as the little robot went deeper, it was destroyed by an unknown object, indicating that there may be living creatures in this underground cave. And the disembowelment girl came for the ancient creatures that might exist.

Eight mercenaries, claiming to be professionals, began to set up lifting devices around the sinkhole. After the ropes were ready, the eight mercenaries sent two of them down into the cave and began to place the lighting equipment.

Next, Lin Fei and the disemboweling girl followed the remaining mercenaries to enter the underground cave through the lifting rope one after another.

With the rope tied around his waist, Lin Fei slowly moved down from the entrance of the big hole through the rope pulley.

After descending for about 200 meters, he landed on the ground.

At this time, the bottom of the cave has been lit up by the lighting facilities set up by the expedition team, and the scenery is very spectacular, milky white stones dripping down in the shape of a sharp cone, small ponds, and irregular caves on the surrounding stone walls, and unknown yellow plants in the cracks of the stones.

After the disembowelment girl went down into the cave, she did not look at the scenery, which did not attract her, but took a test tube to collect samples of water and plants in the pond, and preserved the collected plant samples.

Lin Fei walked around the cave and actually found a broken hat, one with a thick layer of gray from an unknown number of years ago.

"Aren't we the first to come down?" Lin Fei called the disemboweling girl and the eight members of the expedition team over, pointed to the broken hat and said.

Of course, everyone was silent, and no one answered Lin Fei.

"Right now we're just inside the outer cave, and then we're going to go deeper into the cave through the cracks in the rocks for five days." An old man who looked like the leader of the eight-man expedition said, pointing to a large rat-like cavern under the cave walls.

Subsequently, eight explorers and the disembowel woman successively drilled into this large cave. Lin Fei carried the instrument box with an ellipsoid on his back and also began to drill this hole. However, the cave was very narrow, and the stone walls around it squeezed Lin Fei's body.

"Ah" Lin Fei was stuck in the crack of the cave because the equipment was too huge, and he drilled this narrow hole together.

Lin Fei tried to move, but he couldn't move back and forth, in this narrow cave crack, the people in front couldn't come back to rescue Lin Fei at all, with Lin Fei's twisting, the dust in the cave was raised, Lin Fei felt that it was difficult to breathe, and he was likely to be stuck in it.

"Go back to three minutes ago." Lin Fei decisively cast the ability God of War for three minutes (pseudo).

The scene in front of him changed quickly, and Lin Fei returned to the time before entering the cave gap, and the disemboweling woman in front of him was just about to burrow into the cave.

"Ripper, wait and go in, your box with experimental equipment is too big to enter the cave, you pick one or two things to use, and I'll put the rest here for you, and I'll come back and get it when you need it." Lin Fei stopped the rippling girl and said.

"What, you want to put my lab box outside, you just are lazy and don't want to take it, men are unreliable, and they hate to take things for women." The disembowel girl suddenly said such a sentence, and Lin Fei was stunned when she heard it.

But then the disemboweling girl tried the size of the experimental box, pushed into the gap of the cave, and found that she couldn't push it into a corner in the middle, so she could only slowly retreat back, picked a calfskin bag pendant from the experimental box, hung it on her waist, and entered the gap in the cave again.

"Can she be considered a woman? Like more female ghosts. Lin Fei looked at the black-haired rippling woman who entered the crack in the cave and muttered to himself. Then Lin Fei also quickly drilled into the cave gap.

Ten people met in another small cave. This time, there is only one large pond in this small cave.

"The previous detection robot has already detected that this pond is connected to another wide and complex cave, which can be reached by diving into a universe. I've got a breathing mask and power thrusters for you. This underground water area is very large, and there are several forks in the road, so be cautious. The old man, the leader of the expedition, said, and took out eight mask-sized breathing masks and four small powered underwater thrusters.

Before these four small thrusters were opened, they were only the size of a small umbrella, but once they were opened, they would grow longer and bigger, with a huge spiral in front and two handles in the rear, which could be held by two people.

This time, the two members of the expedition team went into the water first, turned on the thrusters and lighting, moved forward, and pulled a rope down.

A cosmic hour later, news came from the front that it had arrived safely.

Then, Lin Fei and the ripper-chambered woman were in a group, holding the handles on the left and right sides of the thruster, and the two of them leaned close together, and through the gears on the rope, they turned on the thruster and moved quickly.

Through the oxygen supply of the respiratory mask, Lin Fei felt a fishy smell, it is likely that the expedition team did not clean the breathing mask after the last use, or since they used the breathing mask, it has not been cleaned, so that the dust and impurities on the oxygen filtration equipment began to smell.
