934 Sky Train

Ye Han didn't know if there was a pit resistance organization in Beidu, but he knew that Beidu's vigilance had never been lowered.

Not only is the locking equipment hidden, but the design of the ground station itself is also hidden, with a fully enclosed structure, a thick outer wall, its own energy supply equipment, and several hidden arsenals inside!

In case the resistance group tears its face, as long as Ye Han takes a group of subordinates to hide in, the ground station can become a fire fortress in a gorgeous instant, unless the aliens sacrifice a shipgun-level heavy weapon, don't think about what the ground station will do.

The successful landing of the ground station means that the main project of the rail elevator has been completed, and the remaining tails are all corners.

However, neither Ye Han nor the resistance group had any idea of delaying the construction period, Ye Han led the soldiers to put the finishing touches on the work overnight, and commanded a large group of aliens to turn straight - open the ground station, pave the exit of the station, and then use the building materials transported to Europin in advance to build two symmetrical simple platforms, at dawn, the main project is completed, and when the concrete is dry, it can be put into use.

At this time, the ground station has changed its appearance, and the diving bell opens two symmetrical gates, each with two straight electromagnetic tracks leading to the simple platform, which looks strange.

The aliens don't care if the ground station is weird or not, let alone whether the concrete is dry or not, the project has just been completed here, and a group of aliens over there are driving car worms over.

They also knew that the rail elevator could make the ground-air communication easier and more convenient, so this time they sent more carbon fiber vines to each time.

The containers in the base had already run out, and Ye Han couldn't let them bring the vines back, so he could only organize the soldiers to receive the vines, classify them according to their quality after inspection, and temporarily pile them near the ground station.

Luo Qi found an opportunity to come to Ye Han's side: "Boss, can you pile it up here?" What if one rain doesn't end up in one fell swoop? ”

"It's okay, I can't get off for a while, at most I'll be transported away at noon." Ye Han said.

Military engineering uses fast-drying cement, and in the most extreme cases, the initial setting only takes one to five minutes, and the final setting can be achieved in five to ten minutes.

The cement used for the platform is not so exaggerated, but the setting time is no more than an hour.

Luo Qi suddenly, thought about it and asked: "Boss, I'll go back to the center of the earth in a while, or ......."

"We'll talk about it later." Ye Han said, "Pay this wave first." ”

He thought that it would not take more than a while to finish harvesting the vines, but he didn't expect that after the resistance organization got the order from the northern capital, he made a desperate effort to expand the original planting area several times, and harvested several times during this time, and the vines he saved were not ordinary, so the car insect transport team ran again and again, Ye Han and the soldiers were busy all afternoon, and the vines that were piled up were almost piled up into a hill, and there was still a steady stream of car worms rushing over.

Ye Han was also dumbfounded at this time, seeing that noon, Ye Han had to stop receiving, leaving two soldiers to guard the vines, and then take the others to the airdrop site.

While the ground was busy collecting vines, the outside was not idle, and several transport ships departed from synchronous orbit and flew around Europa Zero for more than a dozen circles before reaching the low-altitude orbit, and then flew to the designated coordinates for airdropping.

A few minutes later, the sky train with a fallen umbrella on its tail successfully landed.

The alien strong laborers continued to play to their strengths, working together to carry the heavy trains back to the ground station, and the sections were placed together one after another, and then Ye Han led the people to assemble the trains.

The special design made the assembly very easy, and the four sky trains were quickly assembled, and Ye Han immediately organized people to inspect the trains.

The assembled train is like a vertical split, divided into two halves of sausages, and there is a semicircular groove at the bottom of the car that runs through the front and back, and the soldiers drill inside and outside the car, and under the car, whether it is the shell, the bottom of the car, the door or the equipment.

The air-to-sky train is very heavy, and the risk of airdropping is extremely high, even if the fleet has experience in airdropping heavy equipment many times, it still cannot guarantee the safety of the train.

However, if you don't drop it, you can only send the train to Tianhe, and then descend all the way down the cable, which is a long distance and delays.

Some people may say, why not send the train to the low-gauge terminal? That way, the train can reach the ground after 200 kilometers, and the airdrop is much safer.

It's a good idea, but it's not realistic.

The orbital altitude of the low-orbit pier is only more than 200 kilometers, and the spacecraft must maintain sufficient speed at this altitude to be stable in orbit all the time, otherwise it will fall into the atmosphere like a weighing stone, so the transport ship cannot get close to the low-orbit pier at all.

The only human spacecraft that can hover in low orbit is the Skyhook with only eight main engines.

So can't you use the Sky Hook to send the train there?

Still no, because the eight engines of the Sky Hook are all on the side of the battleship, and the propulsion is a miniature nuclear explosion triggered by a laser, so it is very dangerous for such a heavy spaceship to get close to the cable, and any mistake in operation, the laser shot from the reaction cavity has the risk of cutting the cable.

Not only Skyhook, but all spacecraft powered by nuclear engines must be kept at a safe distance from the orbital elevator.

All factors accumulated, and Beidu had to weigh it again and again, and finally chose the airdrop.

In order to ensure that there are no problems, the fleet also deliberately threw a few more carriages, even if they are broken, they will be replaced, so as not to delay the business.

After a while, the train self-inspection and external inspection were all over, no problems were found, the horses on the scene began to carry the vines, and the aliens once again played a major role, contracting all the loading operations, and it only took half an hour to fill all the carriages.

Ye Han took the soldiers to carefully inspect the carriage to ensure that there were no aliens hiding in the carriage.

Everything was ready, but there was no departure ceremony and nothing else extraneous, Ye Han simply announced the departure and announced that the rail elevator was officially put into operation.

The two rails started at the same time, and the heavy sky train immediately levitated, and the guide cable tied to the front of the train was tightened, slowly pulling the train into the ground station.

Two air and sky trains one left and one right at the same time into the ground station, after entering the station along the inclined track, when the end of the slope has been perpendicular to the ground, then the chassis of the two cars is relatively dead together, the groove of the chassis is just stuck in the cable, the two cars become a car, like a worm only attached to the tree along the cable to climb.

It was only at this time that the aliens understood why the space train was designed to look like a ghost with a large semicircle and a small semicircle.

Looking at the train that was climbing higher and higher, Ye Han breathed a long sigh of relief, and suddenly felt that all his efforts had been rewarded.

Not only that, but his heart is also full of expectations, looking forward to the completion of the earth's orbital elevator as soon as possible...... But nothing is in vain without raw materials, and his current task is to harvest the vines sent by the aliens first.
