"Did you see that? It was amazing, I felt like I was in a dream. ”

They fell silent as soon as they entered this strange space, everyone was shocked by the vision in front of them, and forgot to communicate for a while, and it took a while for Mark to break the silence, and the other two also heard his voice, proving that the communicator was still in a normal state and was not disturbed by this strange space.

"What the hell is this......" Nina held out her hand curiously into the air, and it wasn't until she touched the cockpit glass that she realized she was still inside the machine.

"Mark, can we get over there?" Sun Tan asked.

"There's not a lot of fuel for propulsion, and I'll have to leave a little bit out." Mark glanced at the dashboard.

"In that direction, I feel like this is a relay station, used to park spaceships." Sun Tan pointed to a platform in the distance, and Mark turned on the inertial suppression, turned on the thruster, and stopped the mech to the position he was pointing.

After landing, nothing unusual happened, Mark opened the hatch after confirming that it had stopped, and the temperature outside was not abnormal, and he could move normally.

Sun Tan jumped out impatiently, Mark was startled by him, and originally wanted to carefully check the surrounding environment, but he didn't expect Sun Tan to pounce on the wall like a shark smelling blood, and carefully recorded the lines on it, but fortunately he didn't encounter any danger.

In such a completely unknown environment, Mark can't put his mind at ease, the biggest fear of human beings comes from the unknown, the unknown will make people's sense of security drop sharply, in the face of something they don't know at all, any action must be cautious.

It was difficult for civilizations to understand each other, so Mark had to guess that this was a platform where the ship was parked, and the surrounding area was bare as if there was nothing, but if a ship docked in, there should be some corresponding devices stretched out around it. Nina didn't dare to go down, Mark saw that Sun Tan had no problem, so he cautiously poked down, stepping on the white platform felt very strange, Mark lowered his body and touched it, the ground is hard, but there is a soft surface feeling when stepping on it.

It's a material beyond human comprehension, Mark feels like his brain is going to explode, he can't help but feel a little dizzy after receiving so much information in one day, thinking about it, this material reminds him of a space elevator.

Fifteen space elevators have now been built on Earth, and they are ascent orbits made of high-strength nanoalloys, or to put it simply, a tower.

But this is not an ordinary tower, the space elevator is close to the Tower of Babel in ancient myths and legends, the tower of Babel built by humans in an attempt to touch the heavens, the space elevator goes straight to the sky, and due to the special materials, it can reach a height that ordinary materials cannot reach. With the space elevator, the spacecraft no longer needs the high-cost launch method of rocket delivery, only needs to transport it to the edge of the atmosphere through the space elevator, and then reach the first cosmic velocity by a solid-state rocket, and then can break out of the atmosphere and become an orbiting satellite. The cost of launching satellites has dropped dramatically, and in just ten years after the successful construction of the space elevator, the number of orbital satellites launched by mankind has increased nearly 10,000 times, and the low-earth orbit is surrounded by dense satellites, and the number of space stations has reached an astonishing more than 100.

The most huge reform is the new satellite combination technology, the huge space fleet that mankind now has, as well as the giant space station on Calmede and Mars, are all made with this technology, first launch the module satellite into a predetermined orbit, and then use engineering satellites to crack and modify, this technology is known as the cosmic technology revolution, everything before is a small fight, from this step, human beings can be regarded as really stepping on the sea of stars.

Mark had seen the materials for the space elevator before, once in the Museum of Natural Science on Earth, and the other when he was carrying supplies on the moon.

Mark, the first space elevator on the moon, also played a role, and he also climbed the unfinished tower, overlooking everything under the moon, and only climbed to a tenth of the height, and the new city of the moon below was already invisible, and the huge shuttle orbit looked like tiny hairs. At that time, Mark felt nanoalloys, which were just a metal rod as thick as an arm, but they could support hundreds of tons of pressure, a material that was completely beyond common sense, this was Mark's feeling at that time, and his thoughts were the same at the moment.

Everything in this white space is so unreasonable, but it is indeed real, Sun Tan has already pounced on it, he took out a few small instruments from a broken denim bag, connected them and debugged them repeatedly, Mark called him in the communication channel, he did not respond, when Mark walked behind him, Sun Tan suddenly shouted in the channel.

"Be careful! Don't move! ”

"What?" Mark didn't understand what he was doing, and suddenly he shook violently twice, and those delicate blue lines converged on one section of the wall, and then they condensed into a square, and then the pure white wall actually protruded, and in the time they squeezed a few times, the lines outlined into a cube, and actually became a real existence.

"Look, it's lit up." Nina let out a scream as well.

The details on the cube were quickly outlined, turning into a square of gold and white, covered with words and lines, like an ancient stone slab, but its surface was spotless, and every detail exuded the arrogance of a high-level civilization, like the nobility of a god.

"It still starts...... How many years have passed? Mark lamented that if it is human technology, no matter how carefully it is preserved, it is impossible to withstand thousands of years, the life of memory cards is less than 100 years, the chip is longer but not more than 500 years, the pictures painted on silk will inevitably begin to oxidize and fade after thousands of years of wind and frost, even stone sculptures cannot be preserved for more than 10 million years.

"At least more than three billion years ago, the moon is probably created by them for some purpose, but their civilization may have fallen now, at least before the appearance of humans, this place was supposed to be in the open air, but now it is covered by thick moon dust, even on the stationary moon, the vicissitudes of life still exist, but the process is very, very long."
