The No. 3 auxiliary engine maneuvered around the plane outside the orbital plane and finally entered the docking corridor. The distance between it and the target spacecraft had entered a range of 100 meters, with a relative speed of 2.25 meters/sec.

"Enter the docking section!" Chu Siyuan said again.

At this time, the secondary engine uses a measurement system composed of camera sensors and proximity sensors to accurately measure the distance, relative speed and attitude between the two parties. These data are monitored by Chu Siyuan and fed back to the spacecraft central control center.

At this time, Li Chuan was next to the interface, just watching the No. 3 secondary engine "collision" towards him. There was still a sense of oppression, but Li Chuan was still very calm. He has been a person with strong hands-on ability since he was a child, and this time Feitian had learned real skills professionally and programmatically before.

The rendezvous and docking entered a critical stage. The small engine on the secondary engine was turned off before docking and collided with the spacecraft at a docking speed of 0.16 meters per second. At this moment, people inside the spacecraft could clearly feel a slight vibration.

At this time, Li Chuan directly manually used the gripper, buffer, force transmission mechanism and locking mechanism of the docking device to achieve a hard link in structure between the two aircraft, and then slowly floated to the other side of the secondary engine. The jet backpack on the body was loaded with liquid nitrogen, which was used to control space walking.

Open the hatch of the secondary engine and Li Chuan entered the interior to complete the link between the transmission bus, power cord and fluid pipeline.

"The docking is successful, and the No. 3 secondary engine booster completes the link, activates, and completes!" On Chu Siyuan's display panel, the "one" red icon on the external mounting structure on the left side of the spacecraft immediately turned green, indicating that it was successful.

Next, the three additional secondary engines successfully completed the docking mission in about an hour and a half. This efficiency was already very fast, and the mass of the spacecraft increased by more than 200 tons.

"Yuntian 7" completed the transportation and supply mission and began to return. Next was the waiting "Yuntian 3" spacecraft, which sent two small carrier vehicles and a large foldable trailer.

"Yuntian No. 6" brings a large helium three refining equipment airdrop cabin, similar to a small processing plant, a set of drag equipment, and a set of special exploration equipment.

These materials were sent to the "Wentian" spacecraft and were fixed on its external pylon. At this time, the total mass of the spacecraft had exceeded 1,152 tons, which was more than the total mass of the two international space stations.

After working in space for more than six hours in a row, he finally completed the loading mission of all supplies and transporting materials. At this time, the "Wentian" spacecraft looked very tied from its outline, and various large equipment was mounted outside its slender hull, which gave a sense of déjà déjà vu.

After completing the work, the two returned to the spacecraft. After four brand new boost engines were installed on the spacecraft, their power was greatly improved.

In the next hour and a half, the spacecraft circled the earth and finally approached the Huaxia Space Station at an altitude of 397 kilometers. Two pilots of the "Wentian" spacecraft finally entered the space station through a material supply compulsory cabin.

Interestingly, the Huaxia Space Station is as small as a baby in front of the "Wentian" spacecraft. After all, the former has dozens of tons, while the latter has a mass of more than one thousand tons.

With the departure of the two astronauts, Li Chuan became the pilot and captain of the spacecraft. After all, he has been practicing through special living organisms for the past year and a half.

The reason why they didn't bring two astronauts was because they couldn't withstand long accelerations. This time it was the longest voyage in human history. The current record was the United States' Apollo moon landing program, which was only about 400,000 kilometers.

This time, Li Chuan and his team will sail more than 6 million kilometers. During this time, the "Wentian" spacecraft will continue to accelerate to far exceed the third universe speed, reaching 69,984 kilometers per hour, which is equivalent to 55.8 times the speed of sound. The spacecraft is sailing in a large parabola orbit, and the acceleration will be at the limit for a long time, and human physical fitness cannot bear it.

"Li Chuan" and others on the spacecraft are all quantum clones of special living organisms, and their body structure and strength are far superior to those of natural persons.

After sending the two astronauts into the space station, the spacecraft began to accelerate orbital change, breaking through the second cosmic speed all the way, heading towards the moon.

At the same time, the 2028qa1 asteroid is about 8.3 million kilometers away from the Earth and is flying towards the Earth at a speed of more than 38,520 kilometers per hour. According to the established orbit and final speed of the "Wentian" spacecraft, the spacecraft will catch up with the asteroid 370 kilometers away from the Earth, which means that the time left for Li Chuan to stay on the asteroid is only about 96 hours.

The spacecraft finally accelerated to a speed of 57,600 kilometers per hour, sailed 920,000 kilometers along the established orbit within 17 and a half hours, and finally entered the lunar gravitational range.

"Engine shuts down!"

"Prepare the separation procedure in 15 minutes!"

The spacecraft entered the autonomous driving mode, while Li Chuan left the driver's seat and floated all the way into the main cabin. He pressed the communicator on the ear and said in the public frequency: "Liu Jin, Cock, you two move quickly, we don't have much time!"

On the other hand, the two engineers also accelerated the progress under the urging of their boss. Liu Jin used a backpack of 27 dark blue cuboid energy matrix in the energy reserve room in the spacecraft cabin No. 12, and then put on a space suit and walked towards the hatch.

Li Chuan was waiting for them here. When he saw two engineers Liu Jin and Cock coming, he said, "My helium three is up to you. Three tons of base is only more than less."

"No problem, boss, please leave the mission of the lunar helium three collection mission to us!" Liu Jin was confident and promised.

Li Chuan nodded with a smile, raised his hand and slapped a button on the bulkhead accurately. The air in the hatch was drained, and then opened the hatch door for them in person and said with a smile: "Go, two gentlemen of miners."

After fixing the safety cable, the two of them entered the spacewalk together and headed towards the 7th zone rack mounted outside the spacecraft. The two entered the separation main cabin. Liu Jin immediately went to the energy control inner cabin and embedded a matrix strip with a full reserve of more than 2200 trillion joules of energy. With energy, Cock, who was on the other side of the control cabin, activated the entire system and immediately launched the communication: "Boss, ok!"

At this time, Li Chuan, who was at the hatch exit, took back the safety cable, closed the hatch exit and walked towards the cockpit, and said with a smile: "You two are careful, don't 'hang' on the moon. You two are worth 15.6 billion, which is more valuable than all the equipment you carry, do you understand?"

Liu Jin and Cock couldn't help laughing when they heard this. A special living body is more than 7 billion, which is indeed the most expensive among them.

“Seat 7 mount separation!”
Chapter completed!
