The Skylark and its wingmen had just burst out of a misty cloud of garbage, and their vision was wide open, and behind them was a large net that stretched hundreds of kilometers wide, dragging all kinds of garbage that was slowly thick, still immersed in the clouds, and could not see clearly from afar.

Liao Fan habitually wanted to wipe the sweat on his forehead, stretched out his hand, only to find that he was wearing a thick one-piece spacesuit, which saved him from being in space, and the habits he had cultivated on the surface of the earth for decades did not apply here. The new spacesuit has an internal self-circulation system that automatically regulates the humidity and temperature of the air in the spacesuit...... It's just that when Liao Fan was sailing in the garbage cloud just now, he was too nervous to the point of having an excess of endocrine, which no matter how smart a spacesuit is, it can't overcome.

Paying attention to the information on the mask screen, the load has reached seventy percent, and in a few hours, this time the task can be completed, Liao Fan couldn't help but breathe a sigh of relief.

Looking back, I looked at the side screen next to it, this camera is aimed at the earth, from this angle, the earth is still pure sky blue, occasionally covered by atmospheric whirlpools, so pure and beautiful, only occasionally covered by passing objects A certain part, this, that piece, inexplicably reminds people of the cute Dalmatian in a familiar movie.

But compared to the earth, the once beautiful scenery of the moon is no longer completely gone, almost completely covered by reddish-brown lunar red spots, and the bright moon that has been passed down by earthlings for thousands of years has now become so strange.

Well, we will definitely drive the Zerg back and destroy them! Take back our moon! Liao Fan subconsciously clenched his hand, and the earthlings are now relying on this belief to persevere.

The persistence of the wrecker clearance department of the Space Force for more than two years has gnawed away three-fifths of the low-earth orbit material in the earth's star skirt little by little, just like a fool moving a mountain, greatly reducing the probability of collision of the earth's space projectiles. Although it is still not enough to lift a heavy space station of more than 1,000 tons into space, the steps to allow earthlings to move back into space have been greatly accelerated.

This situation continues, and after a while, the most heavyweight plan in the PDC strategic counteroffensive plan, the "ladder" plan, can be officially launched, at that time, the speed of earthlings will be greatly accelerated, and human beings will establish a permanent fast channel from the ground to space for the first time, and the space carrying capacity will be increased by thousands of times, and human beings can really be regarded as having the ability to develop space.

The Sky Ladder Project, as the name suggests, is to build an elevator from the surface of the earth to space, but unlike the high-rise elevator that people on the earth are familiar with, the scale of this space elevator is huge, the technology it contains is intensive, and its investment in manpower and material resources has reached the pinnacle of man-made objects in human history.

However, although it is extravagant, the space elevator is a threshold that human beings cannot cross to improve their space capabilities, and it is a construction plan that all colleagues in the PDC department have been planning since its inception.

Without a space elevator, human beings have always relied on one-time carriers such as rockets for space construction, and each time they carry only tens or hundreds of tons of material, it will never be able to compete with the Zerg. Not only can it not compete with the enemy, but strictly speaking, humanity cannot even be called entering the space age.

Without huge permanent space buildings, it is impossible for mankind to directly build powerful warships, fighters, satellites, and other structures in space, and at the same time, it will not be able to accumulate space combat power of sufficient scale in space orbit.

There is an almost essential difference between a space battleship and a space fighter and a fighter in the atmosphere. This is also something that mankind has woken up to after a painful lesson.

Therefore, even from a purely military point of view, the space elevator is also built by human beings with all their might, and the cost of striking the Zerg on the moon from space is much smaller than that on Earth, which is the overall strategic difference, not like now, only a limited-scale super electromagnetic cannon can threaten the moon, and in every battle, the efficiency of intercepting the Zerg's attacking forces is extremely low.

Without sufficient long-range strike capability in space, mankind will always be in a situation of being passively beaten, and the difference between this must not be calculated.

Not to mention, only with a space elevator, can it be said that it truly has the ability to develop space, and the most important scale of the limitation of the type of objects that have been limited by human space construction has been overcome, then space cities, space airports, and the almost endless space power generation, space manufacturing, etc., which can be used with the current technology of mankind, each of these breakthroughs can be said to be enough to make human space development technology a big step forward.

Therefore, the space elevator can be said to be the most important and critical step towards the future for today's earthlings.

However, before the implementation of the space elevator plan, there is still a threshold to cross, which is the garbage in the earth's star skirt, it can be said that space junk has become the most deadly point in the military defense strategy of the earthlings, no matter which link can not be crossed, which is why Liao Fan's work as space scavengers is so important.

Shouldering such a heavy responsibility, Liao Fan and them are naturally the top priority among all departments of the current Space Force, which can be said to be the initial premise of all strategies.

Liao Fan and the others themselves of course know this, when the members of the wrecker clearance department were selected, these best astronauts can be said to have come voluntarily, and they have been working under high pressure and high load, sacrificing their bodies for family entertainment...... Almost everything that people can enjoy, all people, is for one goal - the future of mankind!

――――――――

Two hours later, Liao Fan called George, the commander of his wingmanship, that their mission had been completed and that it was time to carry out the final step of the wrecker clearance procedure.

The final step of the wrecker procedure requires the two wreckers to carefully drag the "fishing net" to the low earth orbit in the lower part of the star skirt, slow down the speed, and then disconnect from the connection, so that the "fishing net" and its containment objects will naturally crash in the atmosphere by gravity at low speed.

He contacted George, and the two ships re-coordinated and synchronized, entered the final step of the intelligent piloting program, and then turned on the personal computer on the spacesuit, and was about to listen to a piece of music to relax.

Suddenly, a rapid sound signal came from my ears:

"Call, Skylark! Call, TB23! ”

"Quick! Liao Fan, help――――――――――"
