Just after the mines of the moon's underground world were opened, the prototypes that arrived in orbit around the moon also dived down to the surface of the moon after half a circle around the moon.

In the continuous roaring vibration of "boom boom boom ......", seven huge humanoid statues fell rapidly, smashing seven pillars of smoke on the 30-kilometer line between the Dongchang base and the mine exit at intervals of several kilometers.

Where one of the prototypes landed...... Exactly near the exit of the mine!

These mechanical insects will be dispersed immediately after landing, and according to the development model of the East Factory steelmaking base, small robot production lines and steelmaking equipment will be built, and a sub-base will be established at each landing point!

The mechanical worms at the exit of the mine, in addition to half of the construction base, poured into the mine and began to dredge and level the mine along the open opening, and at the same time ...... Surge the Underworld!

In Nie Yun's plan, the East Plant base will be connected with the mine exit, and this connection line will be used as the center to expand to the surrounding areas to complete the expansion plan of the East Plant base!

This will be the moon base on Nie Yunming's surface, and the main mining base in the underground world will be transformed by Nie Yun into an energy crystal mining base and a secret hidden power!

In the face of aliens with unknown strength, Nie Yun has even prepared for the worst plan for the aliens to evacuate the Earth-Moon System once the aliens are obviously hostile and have the scientific and technological strength of a crushing nature, and this underground base is the bridgehead for Nie Yun's counterattack after strategic retreat.

As for the safety of the earth after the strategic retreat, Nie Yun was not too worried.

Judging from the actions of the aliens in the past, at least for a short time, they don't want to destroy the earth or humanity, otherwise they can do it a long time ago.

Even humans who have not yet left the earth can destroy themselves thousands of times, and an advanced civilization with interstellar navigation capabilities can't even be inferior to humans in terms of attack methods, right?

And in this case, it would be too stupid to defend the earth even if he knew that he was not an opponent, what Nie Yun lacked now was not resources, but time!

Of course, this is only Nie Yun's worst plan, the earth and human beings are Nie Yun's roots, unless he has to, he will never choose any gentleman to take revenge, ten years is not too late!

The construction of the lunar base is rapidly unfolding, and the mechanical insects of the underground world are not idle, they begin to devour and dismantle the ant robot production line in the main base, and then build Nie Yun's own small robot production line on the basis of the original factory.

Although the core components and control programs of the production line of this ant robot have been missing, the remaining mechanical parts still allow Nie Yun to reverse the reduction of a small part of the manufacturing process, and after digestion, it is selected and integrated into his own robot production line, which is expected to increase production efficiency by about 10%.

Another gain is the other party's robot battery technology!

They use a honeycomb-shaped high-density energy battery, a one-person-tall ant robot, using a battery plug-in the size of a small backpack, which can work continuously for 3 days at full power, which is about 5 times higher than the energy density of Nie Yun's existing battery pack!

At present, Nie Yun has begun to upgrade the robot production line in all its bases, and carry out battery upgrades and local fine-tuning of the existing small robots, according to conservative estimates, the efficiency of the upgraded robots can be increased by more than 10%, and the battery life is greatly extended.

There was also the scrapped spherical minecart that was badly damaged and abandoned in the warehouse, and Nie Yun had thoroughly analyzed it.

After analysis, this should be a remotely operated unmanned minecart, with advanced automation procedures and a small amount of manual intervention to complete the control.

Although more than half of the space in this spherical minecart was used as a container to transport ore, and the core components were also recovered, Nie Yun still gained a lot.

First of all, a large number of mining records, diary-like records finally allowed Nie Yun to parse a large number of alien language rules.

In the end, Nie Yun got the alien language compression package +1!

It's a completely unfamiliar linguistic system, consisting of a large number of dots and lines that make up text, somewhat like a combination of a QR code and a barcode.

Some of this text is very simple, only one or two dots and lines are needed to form a word, while others are very complex, like reading a QR code.

Nie Yun guessed that the eye nerves of such aliens should be particularly developed and able to quickly distinguish these complex patterns like a scanner, or maybe they also used an additional scanner from the outside?

Unfortunately, there are almost no descriptions of the social and technological aspects of aliens, and there is not even a complete picture of what aliens look like.

In addition to the language information, the damaged thrusters on the minecart also gave Nie Yun a surprise.

This spherical minecart also uses plasma thrusters, but the manufacturing technology is far superior to that of Earth, and its thrust and specific impulse are about twice as high as those used by Nie Yun now.

This thruster is seriously aged, and it seems to have been impacted, and there is a huge breach, but the main structure is still very intact, and this damage has no impact on Nie Yun's analysis work at all.

At this time, Nie Yun was already optimizing and upgrading his propulsion system according to the technology on this thruster.

In addition to these gains, after the mine was opened, Nie Yun also sent all the energy crystals obtained by the mechanical worm from the underground world during this time to "eat soil".

A total of 3 fist-sized energy crystals, 2 were sent to the Sea Wolf by Nie Yun, and one was cut into thin slices and left at the moon base, ready to carry out scientific research related to energy crystals.

This thing is much more dangerous than a nuclear bomb, the high energy density is terrifying, if you study on the earth or the Seawolf, and accidentally make some explosion of the century in the process, then Nie Yun will definitely cry stupidly to himself!

And on the moon, you don't have to worry, and you don't feel sorry if it's blown up.

Moon: "......" (#)

In addition, the relatively complete energy hub in the main mining base has brought Nie Yun a greater harvest!

In addition to the energy extraction method of the energy crystal, the energy transmission line of the aliens has also given Nie Yun considerable inspiration, Nie Yun has already begun to carry out a comprehensive upgrade of the Seawolf's energy line, and the overall energy output power of the Seawolf is expected to increase by 30% on the original basis!

In addition, Nie Yun also added an energy crystal energy supply system to the Seawolf, which can be seamlessly integrated with the existing nuclear fusion energy system if necessary.

Although there are very few energy crystals mined at present, it has not yet reached the point where it can be used as the main energy source on a daily basis, but in terms of the two energy crystals that were sent to the Seawolf......

Not...... Probably can support the Seawolf's violent output for 2 minutes?

Nie Yun had already regarded this energy crystal as an explosive killer weapon!

In this way, the harvest in the lunar relics is slowly turning into Nie Yun's strength, bringing about a transformation for SOS......

"Hmm...... Overall, I'm quite satisfied with the moon's dowry......" Nie Yun smiled.

Moon: "......"
