E City, Blue Heart Cafe in the center of the city.

One of Beaufoy's robots has made an appointment to meet the Underworld.

The Blue Heart Cafe is located on the busiest street in E, where people come and go very conspicuously, and the appearance of Bofoyi's robot is no different from that of a human, so Gu does not arouse anyone's suspicion.

Beaufoyi had been sitting in the café for ten minutes, but the person who had been in contact with him had not come.

After the Underground people snatched the meteorite, Bofoyi made an agreement with the Underground King, and while stabilizing the Hero Association, he secretly cooperated with the Underground King to open the "Holy Stone".

Beauferi has always had a terrifying desire for unknown knowledge, even if he cooperates with strange people, but this time he cooperated with the Underground King to find out the details of the Underground King.

This group of weirdos appeared too suddenly, and what is even more terrifying is that the underground people obviously have their own culture and their own ethnic groups, and they are not comparable to individual weirdos.

But what Beaufoyi didn't expect was that the King of the Underworld would meet with such a conspicuous coffee shop.

Twenty minutes later, just as Beaufoy's patience was running out, a man sat down across from him.

It wasn't the underworld who appeared in front of Bofoyi, in fact, the whole world was searching for the whereabouts of the underground, and there was a wanted notice for the underworld in the coffee shop.

No matter how arrogant the king of the underworld was, he did not dare to meet him in broad daylight in full view of everyone.

The person sitting down was a man in his thirties, with a sven face and a pair of glasses, and after he came, he ordered a cup of coffee and took a sip slowly.

"You're the King of the Underworld?" Beauferi couldn't hold his breath and spoke first.

"Yes, I'm a servant of the Underworld, and my name is Jason!"

"Nice to meet you, Metal Knight!"

Beaufer was a little surprised, because Jason was a 100% human, not a weirdo disguise, but he obeyed the orders of the Underworld, and he could even hear Jason's respect for the Underworld.

It is a kind of respect that comes from the heart, like an ordinary person meeting a spiritual idol.

"Now that the limelight is tight outside, the Underground King specially asked me to guide you!"

After sitting for a while, waiting for the coffee shop to be less crowded, Jason took Bofor and walked into the coffee shop, and the coffee shop staff didn't stop him when they saw it.

"It seems that the power of the underground people is even stronger than I imagined!" The clerk is also obviously the king of the underworld.

The underworld has long planted a large number of undercover agents in the human world!

After the two enter the coffee shop's utility room, Jason opens a small mechanism, revealing a secret door on the other side of the wall.

"This way, please!" Jason motioned for Bofoyi to enter the secret door, and the two descended a long hallway to a rather large basement.

There wasn't much in the basement, except for a portal-like machine that stood out.

The metal machinery, the complex circuit board, and the door-like appearance immediately attracted the attention of Bofroil.

"Space Conversion Door?!" Boffoyi guessed.

Jason smiled: "Lord Metal Knight really has a good eye, this machine is a space conversion device!"

The reason why Bofoyi was surprised was because he did not expect that the technology of the underground people would be many years ahead of humans, because of the space transformation device, even humans have not yet researched it.

Jason seemed to know what Boffoyi was thinking, and he said calmly: "The underground human civilization is thousands of years earlier than the human civilization, and the technology is naturally superior to the human race!"

"Then why are the people of the underground still fighting with cold weapons?"

Previously, at the headquarters of the Hero Association, Bofoyi found that the underground people, including the underground king, were using cold weapons to fight, and instinctively thought that the civilization of the underground people was not developed.

"Because the people of the underground think that technology is only an auxiliary, and a strong physique is the foundation!"

"You're about to travel to the Underworld, and there's something even more amazing to show you!"

Jason came to the "Space Conversion Door", and after carrying Bofo on his back, the Conversion Door opened steadily, revealing a spatial passage.

"The underworld kingdom is a few kilometers below the surface, humans are not underground, they don't have the magic power to drill into the ground, if you want to go, you have to go through the transformation gate!"

After saying that, Jason himself walked into the space passage, and after a pause, Bofoyi also walked in resolutely.

When Bofoyi walked in, the passage of the space automatically closed, but there were no two people in the room.

After entering the space passage, Boffoyi felt that as soon as the screen in front of him dimmed, he lost contact with the robot, and no matter how he operated it, he could not connect to the robot again.

"The signal is blocked, it should be after the space conversion, the signal is broken, if it is really as Jason said, the underground people live thousands of meters below the surface, the robot will not be able to accept the signal!" Dr. Evolution on the side said.

"The Underworld King should know about the robot's signal, why did he lead me to the Underworld?"

"Could it be a conspiracy, that the Underworld wants your robot?"

"Probably not, otherwise he would have the ability to snatch my robot from the headquarters of the Hero Association!" Beaufer said again.

"Besides, with the technology that underground people can create space conversion doors, they can't look down on my robots!"

After a few seconds, the robot that entered the space portal reconnected, and Jason's face reappeared on the computer screen of Boffoy.

"The signal in the space channel is shielded, and now after coming to the underground world, the signal is reconnected!" Jason's words dispelled Boffoyi's doubts, but new doubts arose.

Where did the signal from the underworld come from?

Through the robot's vision, Bofoyi suddenly saw the underground world.

"This is the Underworld!" Jason excitedly pointed to the world path below.

Bofoyi and Jason were standing on a hillside, and as far as the eye could see, there were a series of buildings that were extremely majestic, but different from human architecture.

The round buildings are layered on top of each other, outlining an underground city, prosperous but strange.

On the ceiling of less than 500 meters, an artificial sun is shining brightly, creating light for the dark world.

In a city the size of Z City, it is very lively, every underground person lives like a human society, and Bofoyi even faintly hears a different kind of music.

The world of the underworld is more developed than the human world, and Beaufoyi can see flying machines that he has only seen in movies floating in the air, and groups of soldiers armed with spears patrolling the streets to maintain law and order!

Boffoy and Jack descend the hill and blend into the underground city.

The underworld people did not show strange looks because of the different looks of Jack and Boffoyi, and even some curious underworld children boldly looked at Bofroyi.

The underground people are not enthusiastic, but they are not xenophobic, and Bofoyi walks quietly in the street mountain, enjoying a different style.

If it weren't for the fact that the surrounding buildings were different from humans, and the appearance of the people underneath was very different from humans, Beaufoyi would have thought that he had come to the human world.

Jack led Beaufer through the streets, slowly making his way to the deepest part of the city, stopping when they came to a huge palace.

The palace is semicircular and resplendent in gold, with gold carvings of unknown meaning on the walls, but there is not a single guard in the palace, and the King of the Underworld stands in front of the palace waiting for their arrival.

"Welcome my honored guest to the Underworld!"
