With the vehicle, the speed of the group immediately increased a lot.

Following this spiraling path, the group finally reached the end of the road after forty minutes.

Here they found a large closed gate.

The two drones, which had lost their signals before, were quietly parked in front of the gate.

"Looks like this is the end." Filip said.

Looking at the big gate, Wang Shaojun asked, "Director Fili, can you open this gate." ”

Fili observed for a moment, then walked over to a controller-like device on the edge of the gate.

Dusting off the controller, Fili found that the controller was still usable.

However, Filip noticed that the display on the controller seemed to require a password.

"I'll give it a try." Looking at the controller, Filip said uncertainly.

With the laptop on his wrist turned on, Filet connected the controller via a cable.

After being busy for a while, Fili shook his head and said, "No, the coding language is different from ours. It seems that we have to use artificial intelligence to crack it from the underlying machine code. Unfortunately, we can't get the signal over. ”

"Since the wireless signal can't be transmitted, can we try the wired signal?" Wang Shaojun said suddenly.

Fili's eyes lit up: "This may be a solution." ”

Since there was no way to open the floodgates, the group left here temporarily.

Back on the ground, Filip and the others returned to the eco-zone on a transport plane.

In the ecozone, Braun was already waiting there.

"Hello Minister!" Seeing Braun, Filip hurriedly greeted.

Braun waved his hand and asked about the situation: "How is it, have you found anything?" ”

Filip took out a piece of ore and explained what he had encountered.

Braun's eyes lit up when he heard that there was a man-made gate.

"Great, I didn't expect to be able to find other civilizations here." Braun laughed.

As the Empire's only space agency, Braun has always wanted to explore other civilizations.

Although signs of other civilizations have been found before, it is still more than a year before the other party returns to them.

"Your proposal is very good, immediately send the SCV to build a communication tower there." Braun ordered.

Under Braun's orders, the robots and SCVs in the eco-zone arrived near the entrance of the cave on a transport plane with a large amount of equipment and supplies.

Under the construction of these robots and SCVs, a communication tower was built.

Then there was the wiring, one end of a fiber optic cable connected to the communication tower, and the other end was dragged by the SCV to the cave.

At intervals, the robot and the SCV build transfer stations.

It took two days before the signal was finally received to the gate's controller.

"Signal, communication test."

"Everything works."

"Good, WALL-E is starting to crack."

Braun, who was standing in front of the gate, heard that there was no problem and ordered the artificial intelligence to start cracking.

"Yes, Minister." Vali Road.

WALL-E is the AI steward of the ecoregion and is responsible for most of the machines in this ecoregion.

With Braun's commands, the display on the controller panel quickly changed.

All turned into a series of 0s and 1s, which is the most primitive binary encoding, which is also the original encoding of all machines.

As the minutes passed, the gate slammed slowly and slowly when Braun was a little impatient.

Looking at the open floodgates, Braun smiled happily.

Vali: "Minister, the code has been cracked. I've made a secret cracker based on this code, and it's now on your wrist computer. The follow-up door can be cracked through this cracker. ”

"Very well, thank you Vali."

"You're welcome, Minister."

When the gate was fully opened, Braun found that there was another gate inside.

Seeing this, Braun suddenly thought of something.

"Minister, this should be a transition cabin. It is quite possible that behind the gates, there is an entire ecological zone. Filipe said.

Braun nodded, he thought so too.

The cracker was sent to Wang Shaojun, and Braun motioned for them to clear the way.

After Wang Shaojun received the order, he led the troops into the transition cabin.

By the time they all entered, the first gate was shut.

Wang Shaojun, who had been mentally prepared, was not uneasy, and started cracking through the wrist computer.

Not long after, the second gate was also broken.

When the floodgates opened, another gate was imprinted in front of Wang Shaojun's eyes.

Looking at the gate in front of him, Wang Shaojun had a black line.

After opening three floodgates in a row, Wang Shaojun and the others entered a road again.

Following the passage, Wang Shaojun and the others soon came to the end of the road.

Looking at everything in front of them, Wang Shaojun and the others were stunned.

Looking at Wang Shaojun and his entourage, who returned safely, Braun couldn't wait to ask, "How is it, what's behind the gate." ”

"There are also three gates in the back, and at the fourth and fifth gates, disinfectant will be sprayed down. The fifth gate will not open until the disinfection is complete. Wang Shaojun reported.

"What's the back, what's behind the fifth gate?" Braun asked.

Wang Shaojun said: "It is a passage, and at the end of the passage is a very beautiful scene. ”

"It's great that we've discovered a new ecosystem." Braun was pleasantly surprised.

Since there was no problem with the back, Braun decided to get into it as well.

Through the gates, Braun and the others saw the road.

Following the passage, Braun and the others soon came to an end.

Looking at everything in front of him, Braun was amazed: "What a beautiful environment! ”

At the end of the passage is a lush forest with a variety of birds flying.

Looking back, Braun found themselves in a cave halfway up the mountain.

And this cave is the passage that connects the two areas.

"Look, Minister!" Filip suddenly pointed to the heavenly sun path.

"Oh my God, it's the sun!" Seeing the sun, Braun exclaimed again.

Wang Shaojun was very strange: "Isn't it the sun?" Why so surprised! ”

Fili explained: "Do you think where we are now? It's underground! ”

Wang Shaojun was stunned for a moment, and suddenly understood: "I understand, this is an artificial sun." ”

"Send a drone at once and give me a good reconnaissance of the world." Braun ordered.

With Braun's order, drones were quickly delivered.

Not only that, but the SCV and the robot also built a signal tower on this hill.

Soon, a local area network was built.

Through the internal LAN, one drone after another left the ground.
