Grove, the two doctors, and Zion have consulted and decided to have Mirami carpet scan and analyze the entire Mars, suspend terrestrial exploration, and return to outer space to wait for the discovery to be completed and then sift through the remains found.

Then send a remote-controlled robot to explore to determine safety, and then send an exploration team to conduct manual exploration.

As soon as Grove issued an order to the landing ships to land on Mars, the landing ships immediately began to recall all personnel on the ground.

With the return of all the landing personnel, the landing ship began to evacuate Mars as planned, and returned to the Ark fleet in outer space anew.

It took 60 days for Future to scan and screen all the surfaces of Mars, and found a total of 3 alien ruins, of which only the one found by Xingtian and Ares was suitable for exploration.

The two doctors began to select the members of the exploration team as soon as they determined the location of the exploration. Xingtian and Ares approached Dr. Aaron at the beginning of the selection of personnel, and they strongly asked to participate in the exploration, and Dr. Aaron agreed very happily.

While selecting personnel, the remote-controlled robot exploration team has successfully landed near the alien ruins and begun to explore.

The two robots slowly walked to the gate where the alien ruins were exposed to the ground, and the remote control personnel carefully observed the gate and finally found no place to open it.

Dr. Aron had the robot move clockwise around the gate, expanding the width of the robot outward with each revolution, and finally on lap 6 a robot crushed a very ordinary raised rock.

The ground shook, and the door slowly opened, and the robot waited for the doors to open before leaning towards the door.

Through the robot's video detector, you can see that there is a staircase extending downward in the gate, and the remote control personnel and remote control robot slowly walk down the stairs.

The robot walked down the stairs for about 5 minutes, and when the stairs reached the end, a very flat horizontal corridor appeared in front of everyone.

The robot walked down the hallway and did not stop until it reached a door perpendicular to the ground.

Dr. Aaron and Dr. Hawking carefully analyzed the footage and found that the folding door had to be opened by living beings, because the door did not open after the robot pressed the very obvious opening, but it only emitted a similar error sound.

The current situation is a headache for both Grove and the two doctors, and if the robots are not able to enter the interior of the ruins, they cannot be sure whether the ruins are safe, and if they give up exploration, humanity may lose the opportunity to obtain the technology of alien civilizations.

Just when everyone was helpless, Ares said that a monkey is stronger than a robot, and this sentence made Dr. Aron instantly quite able to let monkeys replace humans to try to open this door.

A monkey wearing a fixed protective suit was sent to this gate, the protective suit worn by the monkey kept raising his hand and pressed the action to the position of the switch in front of the gate, when the monkey pressed the button, the door sounded again, this time it was different from the last time, it seemed to give people the feeling that the test was passed, with the sound of the gate finally moved to one side and retracted into the wall.

The monkey then entered the gate, and the robot from before followed suit. When everyone stared intently at the transmitted footage, a strong light shone on the robot, and the two robots were destroyed instantly, and the picture was interrupted.

However, the video detector on the monkey's protective suit is still transmitting footage, and through this detector, it is found that only two robots have been destroyed, and the monkey has not been attacked.

That is, this alien ruin is only allowed to be entered by living beings. Just when everyone was sure that the creature would not be attacked, the video detector on the monkey's protective suit began to flicker, and the last image was that the door that had just been opened was closed, and the signal was completely cut off as the last crack disappeared.
