The graviton bomb used by Kungo was an unstable device produced by humans, and the probability of using it out of control in the atmosphere was 50%.

At that time, Kunwu's graviton bomb did get out of control, causing a chain reaction, and in the end, a graviton bomb that should have only been 100 meters away from the attack exploded a blank area with a diameter of more than 1,000 meters.

You must know that the explosion range of graviton bombs is always a regular spherical shape, because whether it is air or earth, under the destruction of space gravity, its resistance is the same.

So when Kunwu stood on the edge of the huge pit and looked down, even after a few years, even if there were sandstorms blowing up from time to time, the pit was still hundreds of meters deep.

It looked like a meteorite had fallen from the sky.

"You made a lot of trouble here back then!" Apo couldn't help but sigh.

"I was determined to die. If it weren't for the Doctor's backhand, I'd be dead! ”

Kungo sighed.

Although he knew the truth, he already understood that the massacre in Duanmu was planned, and it was a scene that forced him to choose to merge with the Source of Eternity.

But Kungo didn't blame the doctor, in his heart, the doctor will always be the gentle mother who taught him to love and pull himself from darkness to light.

Ah Po and Kungo have a heart-to-heart connection, and they can naturally feel each other's emotions, and after a moment of silence, he said, "Go down and have a look?" ”

"Let's go!" Kungo nodded and jumped out of the huge pit.

The Golden Ruins on Sangweiqi are a pure Golden Empire city, which means that there are underground buildings here.

This is the architectural style of the Lando people, and the more important the city, the more exaggerated its underground part becomes.

According to Amber's memory, there have even been instances where the entire interior of the planet has been hollowed out.

Kunwu didn't know this back then, and Sang Weiqi was a sad place for him, so he hastily left, and now he has returned, with the purpose of finding the secret buried here, if any.

Because it has been covered by sand and dust for hundreds of meters, Kungo released more than a dozen engineering autonomous robots to help dig holes.

The mechanical squid entwined its tentacles around a strip that turned into a drill, and then its entire body began to spin at high speed.

More than a dozen mechanical squids acted together, and they saw the yellow sand covering the sky, and a huge tunnel was visible to the naked eye in front of Kunwu's eyes.

Soon, the soft sand layer was dug through, then the hard rock layer, and after a ding, the squid stopped.

What appeared in front of Kungo's eyes was a silver-white metal plate.

"The alloy of the armor layer of the battleship, tsk, this dungeon is even more important than imagined. Actually use battleship armor as a shell? Kungo sighed loudly, and then knocked on the shells of the squid, "Dig it up." ”

The mechanical squids shook their tentacle structure and hardness at a high speed, and began to spin wildly again.

This time, there were high-energy beams between the tentacle bits.

"According to the records, the armor layer of the battleship will be used as the shell of the underground building militarized structure, which means that Sang Weiqi was actually a military fortress before?" Abodo.

"But there is only one gold relic in the entire Proxima-08 galaxy, and no gold remains have been found within three light-years of it. What kind of military fortress do you think would be built in such a place? ”

Kun Wu spread his hands: "Don't forget, the current territory of mankind was in the remote countryside of the empire back then, and it was the kind of place where His Majesty the Emperor might not necessarily remember that there was such a territory!" ”

Apo thought for a moment: "But don't forget, this is the closest star system to the solar system where humans originated!" ”

Kungo blinked, "You mean to say that this place was once used to spy on Earth?" Uh, that's supposed to be the base of the Golden Rites? ”

Apo whistled: "Then we have to see the final result." If this was really the site of the Golden Rites, they wouldn't have been active here in the first place, right? How can anyone do an experiment on their own base that can fail at any time? ”

Kungo thought for a moment, "That's not right. I remember when I first entered the Quantum Ghost state with the Doctor and saw the destruction of the city on the ground, the city on the ground seemed to be a fairly normal city at the time! ”

"Did you see the Lando people at the time?" Apo asked.

Kun Wu was stunned for a moment and shook his head: "Yes, this is a standard imperial city, but the people living in it are not Landu people. All I know is that they're standard Type III humans, but I can't tell which race! ”

He told Apo everything he had seen at the time.

Apo pondered for a moment: "Then it is very likely that the city above is just a disguise, and they don't know the situation below, otherwise it would be impossible for no one to think about the situation underground at that time." ”

"And at that time, the city was swallowed up by spatial vortexes, which is an extremely rare natural disaster, and its threat is even more terrifying than that of Xingyao. But it's far easier to suppress than Xingyao. ”

"Where there is an Imperial base, how can there be no space gravitational stabilizer that suppresses the ability of space vortex?"

Kun Wu understood what the other party meant: "This can be regarded as circumstantial evidence, proving that this underground base is not known by the people above at all, and even this base is completely invisible, and even the empire does not know about it?" ”

"At least I think so!" Abodo.

As he spoke, a squid flew out of the borehole and made a beeping sound.

"Oh, has it already been opened? Is there air pressure in it? And the loss system is already running? Okay, let's go! After listening to the squid's report, Kungo jumped into the hole that was still smoking without saying a word.

It can be seen that the walls of the cave have begun to surge around the wall, and it is obvious that the pipe damage system of the base shell has been activated, and efforts are being made to repair the hole.

After ten seconds of free fall, Kungo's eyes lit up, and then he found himself in a huge underground space with a height of 100 meters, and he adjusted slightly to stabilize himself in mid-air.

The dozen or so engineering autodroids immediately surrounded him, the squid's default order - to stand guard by their master without any command.

Kungo looked up at the drill hole above, which had shrunk by two-thirds by this time, and if he had slowed down, he was afraid that the squid would have to drill it again.

Looking around again, Kungo found himself in a place that resembled a warehouse.
