One Thousand Nine Hundred and Forty-Eight Underground Embolism

A few hours later, the tsunami finally stopped. Ye Han originally planned to send the Marines to land immediately, but the tsunami caused by the super nuclear bomb was too strong. It could also cause a tsunami on Earth, let alone Jupiter, which has a slightly lower gravity. A huge tsunami that spreads around the world.

The land that has been ravaged by the tsunami is almost the same as a dead pond. All places that can hold water are filled with seawater, and places that cannot accumulate water are also soaked by seawater. There are forests washed away by the tsunami everywhere, and the sight is Everywhere he looked was a mess.

However, there was something that surprised everyone, and that was that all the buildings that the military left on Europa Zero withstood the impact of the tsunami, including the base station of the orbital elevator and the temporary camp of the garrison.

Ye Han watched the images sent back by the satellite and didn't speak for a long time. He hesitated again and again. Finally, he sighed helplessly and ordered the Marines who were ready to land to disband.

The ground that had just been ravaged by the tsunami was really not suitable for landing. Although forced landing was possible, the combat effectiveness of the landing troops was bound to be restricted by the environment.

On the other hand, the enemy is different. Both the resistance organization and the aliens control a large number of servants, and the servants have wings and can fly. This is very detrimental to the landing troops.

Ye Han would rather wait than suffer unnecessary damage... Anyway, it will take a full year and a half for Europa to catch up with the Earth. There is still time, not less than a few days.

He thought he would have to wait at least a few days, but he did not expect that just one day later, the ground near the landing point was almost dry. Only the fallen trees and collapsed mountains silently told what had happened here.

It is not surprising that this situation occurs, because Io has stopped rotating, and the only continent on Io happens to stay on the inside. The landing site is always under the sun's exposure, and it naturally dries faster than other places.

Ye Han didn't want to delay for another minute, and immediately ordered the Marines to set off after receiving the news.

For this mission, Beiyuezhou equipped the Lone Wolf with a fully-manned marine brigade of more than 400 people.

Ye Han gave an order, and a whole group immediately landed on Europa in the new Swift.

It’s not that we don’t want to send more people, but because Jupiter’s zero gravity is relatively high, the landing craft can only go down with its little power, but can’t fly up again. As a result, how to recover the landing personnel has become a big problem, so the landing must be controlled. number of people, first find out the following situation, and then decide whether to send additional manpower.

Of course, it will be different if the landing force completes its mission. Europa's orbital elevator will always follow. As long as it is sure that it will not be attacked by aliens,

The cable can be lowered at any time.

If the orbital elevator cannot be used, the landing troops can only return to space through the Skyhook system... Today's Skyhook system is not the original Skyhook, but a recovery system that can be placed on ordinary warships. Its principle is the orbital elevator. It's almost the same, except that the cable is shorter, so the recovery hook at the end of the cable cannot stay still at a certain position on the ground, but moves at a certain speed.

The higher the warship flies, the slower the recovery hook moves. If the cable is long enough, it can stop on a static orbit and gently and deftly pick up the landing troops.

However, the warship is not a space station with a balanced orbital elevator. With so many cables installed, there is nothing to do. Therefore, when recovering the landing force, the team members must fly on the landing craft at a certain speed, and then let the landing craft be hung by the recovery hook, so that the landing force can be recovered. Bring it back to space.

For this reason, the Swift landing craft has also been improved accordingly, using the aerodynamic layout of a high-speed aircraft, allowing the landing craft to fly at high speeds in the atmosphere.

The improved Swift's landing speed was also much faster, and it landed at the designated location in a short time. Not far from the landing point was the underground passage that led directly to the center of the earth.

Except for a few team members who stayed to watch the landing craft, the others carried the infrasonic cannon and ran towards the hole. After rushing to the ground, they first set up the infrasonic cannon and roared towards the hole. They stopped after a full three minutes. Send the drone into the hole.

None of the team members who landed in the first round had been to Jupiter Zero, but they had complete information in their armor and knew the situation of this cave very well.

But no one went all the way down, and the place where there was supposed to be a turn turned into a straight line, and where there was supposed to be a fork in the road, there was nothing. Now everyone realized that something was wrong, and everyone stepped up their vigilance to prevent encounters with aliens. Human sneak attack.

The attack did not happen, but the drone hit a wall in the underground cave - this passage was actually blocked more than ten kilometers underground!

This is not a strange thing. Alien nests on the earth often use this method to fight against infrasonic cannons, and everyone has long been accustomed to it.

Without saying a word, the commander led the soldiers into the cave with a wave of his hand and arrived at the location of the blockage in a short time.

Everyone took a brief look and found that there was no difference between the blocked surface and the cave wall. They both looked the same thick... If they weren't thick, they wouldn't be able to block infrasound waves, right?

The squadron leader pointed towards the wall, and the team members responsible for the blasting immediately placed the explosives. After everyone took cover, they immediately detonated the explosives. After a loud noise, a shallow pit more than half a meter deep and one meter wide appeared on the wall.

Before the smoke cleared, the blasters placed explosives again and repeated the previous process. After another explosion, the shallow pit became more than one meter deep.

In this way, with the efforts of the blaster, the hole in the wall became deeper and deeper. After a while, it was five or six meters deep into the wall. However, until the blaster used up the last piece of explosives on his body, he still could not penetrate the wall. .

Although he had already speculated in his mind that this blockage was definitely not simple, the commander still wanted to give it a try, so some team members returned to the ground and asked the Lone Wolf to airdrop explosives, transport them into the cave, and continue blasting.

The Lone Wolf was empty of a ton of explosives in one go... Military explosives are not the black powder used in fireworks. Only a small piece is needed to produce a huge explosive force. Those blasting scenes in the movie can only be regarded as real military explosives. Pediatrics.

But after the demolition crew spent more than four hours and used up all the explosives, the wall was still firmly blocking the hole, with no sign of penetration.

No one knows how thick this wall is, but the enemy knows that humans are most familiar with this passage, so it can be inferred that the enemy will spare no effort when blocking this passage. It is very difficult to blow through the blockage with only ordinary explosives.

The plan to go deep into the earth's core had only just begun, but there was no hope at all. Ye Han was so angry that he simply ordered the landing troops to bomb the passage with nuclear bombs!
