It is very difficult to break through the channel shield of the mysterious cube, but it may be possible to break through the shield of the new life, no matter how advanced the facilities on the new life are, at least it is still the human technology at this stage, and it takes some effort to find the loophole, Sun Tan now has a quantum computer in his hand, and the easiest way to do it is to brute force the other party's key, but that is too time-consuming, and they don't have so much time to waste now, so Sun Tan decided to take a risk.

There is a huge signal transfer station above the geological center, which can be turned into an amplifier by a simple transformation, before Sun Tan got a super communication band from the underground ruins, although it is also the category of traditional electromagnetic communication, but its technology far exceeds the current level of human science and technology, Sun Tan has not yet tested its specific effect, but now there is no chance to experiment at this juncture.

"Can you find the location of the Freshman?" Sun Tan asked.

He and Mark control the central computer in the main control room, and Nina debugs the transmitter at the top of the geological middle school, it is still very difficult for her to have such a large workload alone, fortunately, there are a lot of drones used to carry heavy objects in the warehouse, Mark controls a few in the control room to help her complete a lot of work, this kind of drone is completely different from the same thing as the model aircraft on the earth, air and land, the maximum load can be close to five tons, and more things can be carried in the low gravity environment of the moon, and each machine is also equipped with a multi-functional welding headto complete some simple engineering tasks.

"No, they must have turned on the radar jamming, and they can only roughly estimate the direction." Nina said, the space above was very narrow, full of all kinds of debris, and Mark kept controlling the drone to cut through the iron plate in front of her to make a way for her.

"It's fine, try to be as precise as possible." Sun Tan connected the memory into the memory of the central computer, separated the extracted mysterious frequency band, and guided Nina to modify the amplifier while busy with the work at hand.

Dressed in a simple engineering exoskeleton and neatly switching between tools and performing delicate adjustments, Nina didn't know much about mechanical engineering, but she could still do this level of work.

She is not the same as Mark and Sun Tan, Nina was born in a wealthy family, and received super-intellectual education from the time, super-intellectual was just an expensive auxiliary interventional treatment for young children with underdeveloped brains, and later because of an accident, researchers found that by stimulating specific cerebral cortex regions, people's learning ability can be greatly improved, and the children who have undergone this surgery not only restore the intelligence of normal children, but also never forget in learning, all the way, Soon the use of super-intelligent correction on normal children was banned worldwide, and only a small number of low-intelligence children who met the requirements could be used. But in places like the moon and space city, where the laws are not perfect, such surgeries are still carried out secretly, and there are no longer a few people who have undergone supernatural correction, and now almost half of the people in the lunar government and research institutions have received superintelligence correction when they were children.

Now that the technology has advanced to a higher level, it is said that the real experiment of the technology that writes knowledge directly into the brain, although it is defined as illegal by governments, is so tempting that no amount of suppression can stop it.

As a result, Nina has done even better than Mark, who has been doing engineering assignments for several years, just by receiving simple instructions.

Mark was much more idle, and the roof frame was quickly remodeled, as Mark sawed off the lower supports, tilted the entire launcher over, and aimed it at the sky above, leaving him with nothing to do.

"Nina, how's your side? Do you need me to help you? Mark asked, he can now see Nina through the camera on the drone.

"It's okay, I can do it alone, the structure above is not very stable, and I can't stand the toss."

"Be careful, I'll pick you up below, and if there's a problem, say it."

"Hahaha, I'm not a child, don't worry, I'm very reliable."

Their work is proceeding step by step, and the progress is also very fast, Sun Tan has basically completed the loading, the geological center originally had a perfect signal transmission system, Sun Tan can simply modify its program, it may not be able to run perfectly, as long as it can barely catch up with the new number online.

However, at this time, things did not go smoothly as they expected, and suddenly there was a strange vibration on the roof, and the monitoring screen prepared by Mark suddenly went blank, as if it was disturbed by a strong signal, and at the same time, the alarm lights in the geological center also turned on, and the blood-red light illuminated the entire hall.

"Holy! What happened? Mark bounced off his chair with a swipe.

"I don't know, but there must be an intruder coming in." Sun Tan quickly operated the security system and put the internal security monitoring network diagram on the screen.

The green lines on the base map have two prominent red dots, which are the locations of the violent destruction, and it appears that the enemy has attacked from the flanks.

There are no solid defenses in the geological center, and the isolation door is also a civilian model, which can be opened with just two shots, and it is very passive once it is attacked by the enemy, but at this time Mark They have no way to leave.

"Do we have weapons?" Sun Tan asked.

"Is that mech running out of bullets?" Mark smiled wryly.

"You go and see the situation on the roof first, and I'll find a way to drag it out."

"You're thinking of a! Hurry up and get the coms right, I'll go over to deal with them when I get on the rooftop!" Mark flipped into the mech and quickly closed the cockpit door, "I'm not that smart, but I'll do it my own way...... Do your best to protect the earth, you don't have to worry, do your own thing, and the rest ......"

"Just leave it to me."

Mark turned on the machine and rushed to the roof along the rear fire escape, the situation above was not as messy as Mark had imagined, and the structures they had erected before had not been damaged, and it seemed that it was not caused by air raids.

"Nina! Where are you? Can you hear me? Mark searched for her as he shouted through the communication channel, and then Mark saw a figure hanging on it, struggling to climb up.
