Nine Hundred and Thirty-Four Sky Train

934 Space Train

Ye Han didn't know whether Beidu had any intention of pitting the resistance organization, but he knew that Beidu had never let down its guard.

Not only was there a hidden mechanism in the locking device, but the design of the ground station itself also had hidden mechanisms. It had a fully enclosed structure, a thick outer wall, and its own power supply equipment. There were also several hidden arsenals inside!

If the resistance organization broke up, Ye Han could just take his men and hide in there. The ground station would instantly become a firepower fortress. Unless the aliens used heavy weapons of the ship gun level, they would not be able to do anything to the ground station.

The successful landing of the ground station meant that the main part of the orbital elevator project was completed, and the remaining tails were all minor details.

However, neither Ye Han nor the resistance organization had the idea of ​​delaying the construction period. Ye Han led the soldiers to work overnight to finish the work, and commanded a large group of aliens to run around - open the ground station, pave the exit, and then use the building materials transported to Jupiter's moon Zero in advance to build two symmetrical simple platforms. At dawn, the main project was completed and the concrete was dry and ready for use.

At this time, the ground station has changed its appearance. The diving bell opens two symmetrical doors. Outside each door, there are two straight electromagnetic tracks leading to the simple platform, which looks weird.

The aliens don't care whether the ground station is weird or not, let alone whether the concrete is dry or not. As soon as the project is finished, a group of aliens drive the bugs over.

They also know that the rail elevator can make ground-to-air communication simpler and more convenient, so this time, the carbon fiber vines sent are more.

The containers in the base have been used up long ago, and Ye Han can't let them take the vines back. He can only organize the soldiers to receive the vines, classify them according to quality after inspection, and temporarily pile them near the ground station.

Luo Qi found an opportunity to get close to Ye Han: "Boss, can we pile them here? What if it rains and they are all gone?"

"It's okay. It won't rain for a while. At most, we can transport them away at noon." Ye Han said.

Military engineering uses quick-drying cement. In the most extreme case, it only takes one to five minutes for the initial setting and five to ten minutes for the final setting.

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

Luo Qi suddenly realized, thought about it and asked again: "Boss, should I go back to the center of the earth later, or..."

"Let's talk about it later." Ye Han said, "Pay this wave first."

He thought it would not take long to harvest all the vines, but he did not expect that the resistance organization would work hard after getting the order from Beidu, expanding the original planting area several times, plus harvesting several times during this period, the vines accumulated were not ordinary, so the car bug transport team ran again and again, Ye Han led the soldiers to work all afternoon, and the piled vines were almost piled into a small mountain, and there was still a steady stream of car bugs rushing over.

Ye Han was also dumbfounded. It was noon, and Ye Han had to stop receiving. After leaving two soldiers to guard the vines, he took the others to the airdrop site.

While the ground was busy harvesting vines, the outside was not idle either. Several transport ships left the synchronous orbit and flew around Jupiter's moon Zero for more than ten circles before reaching the low-altitude orbit, and then flew to the designated coordinates for airdrop.

A few minutes later, the space train with a parachute tied to its tail landed successfully.

The alien strong laborers continued to use their strengths and worked together to lift the heavy trains back to the ground station, and then put them together head to tail. Then Ye Han led the team to assemble the trains.

The special design made assembly very simple. The four space trains were quickly assembled, and Ye Han immediately organized people to check the trains.

The assembled trains were like sausages cut in half by a knife. There was also a semicircular groove running through the front and back of the train. The soldiers drilled in and out of the trains and under the trains, checking the shell, the bottom, the doors and the equipment.

The space train is very heavy and the risk of airdrop is extremely high. Even if the fleet has had experience in airdropping heavy equipment many times, it still cannot guarantee the safety of the train.

But if it is not airdropped, the train can only be sent to Tianhe and then descended along the cable. The distance is long and it takes time.

Some people may say, why not send the train to the low-orbit dock? In that case, the train can reach the ground in 200 kilometers, and airdrop is much safer.

Although the idea is good, it is very impractical.

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

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

So can't the Skyhook be used to send the train?

Still no, because the eight engines of the Skyhook are all on the side of the warship, and the propulsion is a micro-nuclear explosion caused by lasers. It is very dangerous for such a heavy spacecraft to get close to the cable. Any operational error will cause the laser emitted from the reaction chamber to cut the cable.

Not only the Skyhook, but any spacecraft driven by a nuclear-powered engine must keep a sufficient safe distance from the orbital elevator.

With all the factors accumulated together, Beidu had to weigh them again and again and finally chose airdrop.

In order to ensure that there would be no problems, the fleet also deliberately dropped a few more carriages, so that even if they were broken, there would be replacements to avoid delaying the work.

After a while, the train's self-inspection and external inspection were all completed, and no problems were found. The on-site immediately began to move the vines. The aliens once again played a major role and contracted all the loading operations. It only took half an hour to fill all the carriages.

Ye Han led the soldiers to carefully check the carriages to ensure that there were no aliens hiding in the carriages.

Everything was ready, but there was no departure ceremony or other irrelevant things. 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 space train immediately floated up. The guide rope tied to the front of the train was tightened, and the train was slowly pulled into the ground station.

The two space trains entered the ground station at the same time, one on the left and one on the right. After entering the station, they ran along the inclined track. When they reached the end of the slope, they were already perpendicular to the ground. Then the chassis of the two cars were locked together, and the grooves of the chassis were just stuck in the cable. The two cars became one car and climbed along the cable like a bug attached to a tree.

It was not until this time that the aliens understood why the space train was designed to look like a large semicircle inside a small semicircle.

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

Not only that, he was also full of expectations, looking forward to the early completion of the Earth's orbital elevator... But without the raw materials, nothing would work, and his current task was to collect all the vines sent by the aliens.
