A land heavy firepower platform with all weapons and equipment removed was used to load the legendary Tsar nuclear bomb, and the remaining soldiers were still divided according to the previous tactical squad, and the tasks were assigned under the leadership of Shen Yue, the escort was responsible for escorting, the reconnaissance was responsible for support, and the support was responsible for support, with an orderly division of labor.

This is actually a big operation, with 100 people participating, and no one choosing to quit, not only for the sake of rich merit, enough for each of them to change a piece of land with an area of more than 1,000 square meters and a manor in the Moon City, but also out of their own requirements, not expecting to end the mission in nothing.

The rift area has been much quieter recently, and the unknown resistance has become smaller, so they walked in the opposite direction along the underground passage that the unknown gushed out.

Boundless darkness, turn on the night vision mode, the road becomes better, they quickly go down, because of the communication interruption problem, the digital battlefield is offline, most of the unmanned units must be next to 100 meters to work normally, do not know the road, and have to manually draw maps on the retina screen, so as not to get lost, the only network to maintain communication, can only be effective between two people who are no more than 50 meters away.

Going deeper into the passage like this, even inside the passage, it was also unusually quiet, as if the enemy had been completely destroyed, but everyone knew that it was impossible, and it would be a joke for such a powerful enemy to perish just like this.

Pluto is 3 kilometers underground, the road becomes complicated, full of porous rocks formed after the magma recedes, due to the deep underground, the temperature cannot be transmitted, and the pressure, the flowing magma, it feels like returning to the earth, the temperature continues to rise, the unstable geological structure will bury them at any time, the only good thing is that due to the low gravity, they can easily climb out.

But after crawling out, whether they still remember their location and know how to get out will become their biggest problem, and the employees present even suspect that the reason why they rarely go out on a large scale is because the underground is too complicated, and they are just lost.

Anyway, by this location, the mission goal is getting closer and closer.

"It went so well." Qiao Canal sighed, thinking that he didn't encounter unknown obstacles along the way, but unfortunately, his words always seemed to come true, and at this time, the reconnaissance team in front of him had already exchanged fire with the unknown.

In the dense passage, the unknown combat power is easier to play, and in the same way, it is easier for everyone to gather fire, hold a narrow passage, and quietly wait for the unknown to take the bait, more than 3 tactical squads cooperate with each other to control the situation in the blink of an eye.

Stepping on more than a dozen unknown corpses, they reorganized their squad, not knowing whether the enemy had a means of communication, beckoning each other to speed up their advance.

Soon, a large unknown head joined the battlefield, making them feel psychological pressure, underground, without the assistance of beam cannons,

The big unknown is almost unsolvable, and they have to choose another path to bypass.

Following a road that takes a sharp turn and goes 7 kilometers underground, the world around you opens up.

It was a series of passages, each more than 50 meters wide, and there was no doubt that the builders of the passages were unknown, and along the direction of the passages, they would have a chance to find the unknown lair, the end of everything.

Seeing this, everyone's hearts raced, and they scanned the surroundings vigilantly, knowing that the closer they were to the unknown lair, the more enemies they would encounter, even the ones they couldn't resist at all.

But at the same time, the closer you get to the lair, the better the explosion effect of the Tsar's nuclear bomb will be, enough to wipe out the enemy and completely ease the situation on Pluto.

1 km, 2 km ... Just when everyone was puzzled why they didn't encounter the enemy, an unknown number of more than 100 appeared ahead.

It was the first time they saw such a large number of enemies, divided into several waves and surging in, and the remaining tactical squads did not dare to fight separately, and gathered together to resist.

The exchange of fire was fierce, and from time to time soldiers were wounded, bleeding, broken bones... By the time this wave is resolved, they know that this is their last chance, and if there is another wave of unknowns, they will not be able to hold on.

"Hurry up and run!"

Driven by Shen Yue, the soldiers ran, and even tried to push the land heavy firepower platform, they continued to accelerate to break through layer after layer of unknown blockades, and after crossing the 500-meter-long blockade line, they came to an empty world.

A world that stands tall and hollow, full of flowing lava, and there is an astonishing heat rising around it, but what they were most shocked by was that they saw a tentacle several kilometers long, lying quietly in the magma, motionless, without the slightest sign of being melted by the magma.

"Is this the real unknown?" Seeing this scene, they knew that what appeared in front of them must be a boss, because so far, they had never seen any life with such a large size, not even elephants, blue whales, and even extinct dinosaurs would not grow so big.

Bigger means stronger, is the subconscious perception of all people, even if the huge unknown is motionless several kilometers away, it is almost as if they are dead, and no one thinks that it is a wise choice for them to get closer.

"Here!" Shen Yue gave an order, and the soldiers in charge of escorting it found a way to put the Tsar nuclear bomb in a hidden place so as not to be discovered by the enemy, enter the password on the screen, and start the detonation process.

Relying on their knowledge of the unknown, this group of beings who have not shown obvious intelligence for the time being will never know what this thing is, so after they have completed these operations, everyone has settled down and hurriedly evacuated.

The retreat was chaotic because the unknown was stuck behind.

At least 20 employees were injured to varying degrees, and they had to rely on the assistance of others to abandon their comrades, which is a choice question that normal people do not want to do.

Even so, the battle just now was too chaotic, scattered hundreds of meters, there were still 3 employees who were injured many times by a large unknown person, and they could not die anymore, and even their skulls were completely shattered, and they had to bury their bones elsewhere.

Everyone activated the jetpack they had brought with them, and as the blue light spewed out, they quickly returned along the path they had come from, Pluto's extremely light gravity allowed them to move almost afloat, reaching 20 m/s or even 30 m/s.

There are still unknown obstacles along the way, but they don't care about anything, knowing that in 1 hour, this place will completely turn into a hell of death, and there is no point in dwelling here.
