In March 2037, Zhang Ruike and Ning Yan'er, who are subordinate to the combat department, will separately command two spacecraft to patrol the battlefield at an altitude of 10 kilometers above Pluto.

As the 350mm large-caliber electromagnetic cannon built on the land base spit out its warhead and crashed down on the battlefield, shattering the spire-shaped that had just been built, the firepower began to pour frantically on the battlefield, building a covering firepower network of land and air coordination.

Unknown found that the lair had been attacked, and it poured out more and more frantically, scattering like a tide towards the chaotic battlefield, except for a few tentacle-type, tentacle-type II. waiting in place, attacking the incoming soldiers with the help of giant tentacles or energy beams.

Several strong lines of defense, consisting of unmanned units and soldiers, were set up in the valley area 5 kilometers away from the target to intercept unknown outflows and prevent them from disrupting the course of operations on the underground front.

The battle escalated rapidly, and in less than half an hour, according to rough estimates from overhead satellites, they had eliminated an unknown number of more than 1,000 heads, and it was still growing at an alarming rate.

And as the offensive here became more and more ferocious, there was a commotion around it, and from time to time some unknown people from afar appeared, causing harassment to the battlefield, and the unknown number on the ground alone increased to 10,000.

The ground was littered with unknown corpses, including the tentacle type, the tentacle type II., after being hit by rounds of beams and electromagnetic guns, their bodies were completely annihilated, shattered, and turned into stumps and severed limbs on the smoke-filled battlefield.

As a price, in addition to the corpses of the enemy, the battlefield is full of falling and burning unmanned attack aircraft wreckage, long deformed and distorted land heavy firepower platforms, and even spaceships that were hit by beams and crashed in the center of the battlefield.

In the depths of the unknown nest, the sturdy pyramid-shaped nest was finally bombarded by electromagnetic cannons, as if it was a broken crystal, turning into countless beautiful polyhedral structures, which naturally collapsed under the action of gravity, and the dark fog filled out and vaguely saw the unknown of the new life inside.

On the sky shrouded by countless spaceships, the beam from the tentacle II type penetrated nearly 100 kilometers, hitting the large spaceship of the polar bear country that was steadily attacking at the feet, starting from the direction of the bow, the beam swept through, and finally left from the stern direction, leaving a long crack, and the high temperature of more than 100,000 degrees Celsius triggered the explosion of the reactor, and the nearly 500 soldiers on the spaceship did not have any survivors, and directly turned into a brilliant light explosion overhead.

Xiao Guanhai, the commander of the third-party forces, pointed around Fang Yuan's battlefield of tens of square meters and kilometers, and issued orders from time to time, accurately controlling the smallest or even squad-level troops to carry out tactical tasks, while Cao Chuan stared at the battle line underground.

The 100 teams composed of the elite of the East Galaxy Company, dressed in exoskeleton armor, use the excavation power of the underground assault platform to advance underground, because no one knows what the specific situation is underground, and they have to face all kinds of accidents in the depths of the underground at all times.

Rushing to the front is Shen Yue, as a deputy minister, there is no need for him to take the lead, in order to complete such an arduous mission, a strong sense of responsibility makes him have to go out in person.

It didn't take long for them to encounter geological collapses, some of which were simply caused by loose geological structures, and some of which were simply caused by occasional tremors overhead.

They then encountered several underground passages opened up by the unknown, and it might be easier to travel along the underground passages, but at the same time, if they were such a small person, if they had a head-on conflict with the dense unknown underground, they would undoubtedly kill themselves.

The underground assault platform they were riding on was temporarily coated with a layer of special identification materials, so that Cao Chuan could clearly know where they were and what they were doing underground with the help of deep geological exploration equipment.

Even so, they still can't communicate, they don't even have a vague view of the current depth, and it's very easy to get lost, the only good thing is that with the underground assault platform, they can lurk underground for a long time, and even drill a path on their own, without having to go forward with the unknown like the last time.

The travel speed of the underground assault platform is 5 km/s, and the speed will decrease when it encounters a hard rock mass, and it is about half a day after the outbreak of the battle that Cao Chuan saw that as many as 10 platforms sent out to carry out the mission are approaching the target one after another.

0.5 kilometers away from the coordinate location, Team 2 encountered a headache, an unknown and numerous lair, there was no way to contact others, the only way was to try to fight first.

In another underground, Team 6 was full of luck, at a depth of 18 kilometers underground, there was no sign of unknown activity, they greeted each other, trying to unload the huge 500 million tons of nuclear warhead carried by the platform, set a timed explosion time of 12 o'clock the next day, and then took out a special layer of special cloth with heat isolation and microwave, and covered it on the warhead to reduce the probability of it being noticed.

Immediately after that, they had to continue to move farther away, they knew that even the Tsar's nuclear bomb could not destroy the terrible unknown body, even if the magnitude of the nuclear bomb used this time rose to 500 million, the real purpose was to change the geological structure of the rift area and completely destroy it.

The use of underground nuclear explosions to cause earthquakes was the prototype of the Soviet "Mercury" program, but unfortunately in the era of supercomputers and the time to understand the mechanisms of geological activity, it was simply impossible to precisely control the effects of nuclear explosions.

Today, half a century later, Cao Chuan has a full grasp of many disciplines, so he can do similar things, build a model, and directly poke a hole in the battlefield through the accumulated pressure generated by multi-point nuclear bombs, which is what he has to do.

Therefore, at this time, Team 6 is heading towards the second destination, intending to deploy the second nuclear warhead, and if it goes well, a total of 10 squads will deploy 20 nuclear bombs, ensuring that more than half of them are successfully deployed, and their plan will be successful.
