Sun Tan has just used the instrument to simulate the landing signal of the spacecraft, of course, this must be different from the information of the lost civilization, Sun Tan is just holding the mentality of trying it out, he thinks that the more advanced the civilization, the wider the area of the signal should be larger rather than narrower, this base is still operating normally, first of all, it has an almost endless energy source, and secondly, there must be something similar to AI in management, this AI may react to low-level signals.

Just like ants can't understand humans, but humans can interpret the chemical signals of ants, the flying of bees, and the mysterious language between various animals, humans do not use chemical signals to communicate, but it does not mean that they cannot understand.

Sun Tan's goal is not far away, the lost civilization is too far away for human beings, it is almost impossible to decipher their technology, and Sun Tan does not want to do this, although these things are huge treasures for human beings, but the earth does not have so much time to wait now.

So there was only one thing Sun Tan wanted – language.

Deciphering the civilization's language and signaling methods to stop the mysterious cube from hijacking the Earth is the most feasible plan today.

"Mark, give that to me." Sun Tan looked at the cube and took a deep breath, it should be the incarnation of the management AI, he is now going to use long-wave communication to communicate with it, and then record the signal it releases originally.

"Are you sure you want to do that?" Mark suddenly became worried, in case they triggered some alarm, I am afraid that he would not even know how to die, he was already very afraid of the unknown environment, and his fear was even stronger after learning that this place was still functioning.

"We had no choice but to take a gamble." Sun Tan nodded and held out his hand to Mark.

"Trust him, you see, we just need to work together to find this place so quickly, if you didn't trust me, we wouldn't be here, it's time for us to trust him." Nina also said on the side.

"Alright then, it's all up to you." Mark took off the antique launcher from his waist and handed it to Sun Tan, holding his hand heavily as he handed it over, "Success or failure is here." ”

"I know." Sun Tan skillfully turned on the instrument and switched different bands to send signals to the block.

At first, the other party did not respond, Sun Tan's forehead also began to ooze cold sweat, knowing that the opportunity to save the earth was in front of him, but he had no way, this powerlessness was unbearable, just when they were about to give up, suddenly the square flashed, Sun Tan's eyes appeared a light, and he hurriedly recorded the signal used by the other party at this moment.

The characters in the center of the square also began to flash rapidly, Mark was standing far away, but he also felt something pinch his heart, his eyes suddenly went black, he was restrained by a force of gravity, and it took about three or four minutes to ease up, Nina and Sun Tan were also similar to him, Sun Tan ended the communication, and the square quickly returned to the wall, and everything around it was blank again.

"You...... You guys...... You okay? Mark hurriedly inquired about their situation, and the voices of Sun Tan and Nina came one after another, which reassured him a lot.

"It's fine, it's just a little uncomfortable, it's a weird feeling." Nina let out a few hurried **sucks.

"I intercepted it, but only partially." Sun Tan's face was pale, he was closest to that square, and he was the most affected, but that couldn't stop his excitement, "That thing used at least dozens of methods to communicate with us just now, electromagnetic waves, gravitational waves, and optical frequency signals...... I recorded what we knew, but there were probably many more communications that we didn't know. ”

"What do we do next? Can you stop it if you send it to the Mystery Cube? Mark asked hurriedly.

"It will take a little time...... Sun Tan looked at the antique machine in his hand, his grandfather must not have thought that it would one day when he invented it...... can come in handy for this.

"Why not?"

"We need a larger signal emission source, and we can't break through the other party's signal barrier with this frequency, but we're halfway there, if we can take this thing away......" Sun Tan looked at the wall over there reluctantly, and began to think about how to steal a little more technology.

"Don't don't, don't mess around, thank God we didn't get killed by the automatic defense or something, I can't stand it if you get it again." Mark smiled bitterly and waved his hand again and again, just the unknown communication signal of the other party was about to kill him, if he continued to mess around Mark was worried about what trouble would happen, it was nothing if something happened to a few of them, but he was afraid of this chance to save the earth, so he was buried in the ground in a daze, wouldn't it be too ridiculous.

"Also, if you cause damage, it will be troublesome, and these things should be enough." Sun Tan gathered everyone together and entered the mecha again, and now he has to find a way to get out.

Mark glanced at the dashboard, didn't know if he didn't look at it, and was shocked when he saw it, they had actually fallen more than five hundred meters now! This is not yet seen, the lost civilization that built this relay station in the first place...... What kind of monsters are you going to store?

The walls around were almost smooth, and the friction of this mysterious material was less than anything known to mankind today, and it was impossible to climb against the walls, so Mark had to fly out with an ion thruster, push a section and turn off the engine buffer, and barely get back to the ground by the most energy-efficient method.

The first thing after going out is to seal the hole, once the Minsk government knows about the existence of this place, I don't know what action will be taken, in short, it will not be to save the earth, Minsk's current policy can be seen that his ambitions have been exposed, and the hijacking of the earth is the most suitable time for him to establish a dictatorship, he can't wait for the aliens to chew the earth and swallow it, and never come back. Even if they knew about the technology of a lost civilization, Minsk would seal it off for themselves to study slowly.

"If we want to break through the signal shield, we can't do it alone." After Sun Tan came out, he pondered for a long time, and said something like this, "The resources we have in our hands are too small, and now we have to find a way to find helpers." ”
