Speaking of which, Chu Tianjiang understood Niseya's intentions.

Obviously, Niseya said so much just to let Chu Tianjiang know that the strength he has now may not be able to defeat the powerful Suoya. If Suoya mastered the method of using the star core, then Chu Tianjiang must master the same method, otherwise he would not be Suoya's opponent at all.

"Don't worry, I'll ask you when I see Soya."

"Are you sure?"

Chu Tianjiang smiled and said, "I came here, and I found you, and I also obtained so many star cores, of course I am sure." ”

"I believe in your strength, but you must not take it lightly."

"If I'm not mistaken, that's why you left the Freedom Defenders." Chu Tianjiang changed the subject, so as not to let Niseya speak thoroughly.

Niseya was stunned for a moment, then said with a wry smile: "It's not just me, everyone else is the same. ”

"Others?"

Nisaia sighed and said, "During the Three Hundred Years War, in order to obtain information about the enemy, many people like me came to the Aerial World, and without exception, they joined the Empire, became citizens of the Empire, and when the time came, they triggered the memory trap and began to serve the organization. Although after the end of the war, my communication with other people was completely cut off, and in order to survive in the air world, we all made necessary precautions, such as changing our faces and developing our own power, but as far as I know, almost every air city has a similar organization, and the identity of the leader of the organization is similar to mine. ”

"So many?"

Nisea nodded and said, "This is still a conservative estimate, they are just like me, they have doubts about Soya's position, and believe that the crushing defeat we suffered is directly related to Soya's identity. Although we didn't do anything to be sorry for the organization, we had to cut ties with the organization out of self-preservation. To put it bluntly, in the current situation, if we reveal our identity, the organization will not be able to help. ”

"So, do they all know the prophecy?"

Niseya was stunned again, and at the same time looked at Chu Tianjiang in surprise.

"Of course, not everyone believes that prophecy." Chu Tianjiang smiled faintly and said, "If you can, or if you believe in that prophecy, help me contact them and get them ready." ”

"Ready?"

"When I come back from the Underground World Realm, this World Realm will definitely undergo earth-shaking changes."

"What do you want to do?"

"Don't worry, since I promised not to change the status quo of human civilization, I won't do anything stupid. It's just that we must put an end to the rule of the Empire. Chu Tianjiang paused slightly, and then said, "The key is that after overthrowing the empire, someone must clean up the mess, establish a new ruling order, and manage every city in the sky, so that the hundreds of billions of people in this world can live in peace." ”

"You ......"

"Of course, you're just getting ready. Don't act rashly until I come back. ”

"So, you're confident?"

Chu Tianjiang smiled and said, "Actually, I don't have any confidence, but I can't wait until that time to prepare." ”

Nisaia smiled too, but reluctantly.

"Either way, there's always a silver lining, right?"

"Since you think so, I'll do what you ask. However, I can't guarantee that the resistance groups in other air cities will not stand on the same side as us. Nisea sighed and said, "After all, this situation has been maintained for five hundred years, and not everyone wants to change. In fact, in the Aerial World, the vast majority of ordinary people do not want change. ”

"I know that, but we know better that the empire built by Graham will only lead to the destruction of human civilization."

Niseya frowned tightly and did not comment on Chu Tianjiang's words.

"Alright, so be it." Chu Tianjiang took the initiative to end the topic. "If I hadn't come back, nothing would have changed in this world. If I come back, then what you do next will determine to a great extent the impact on this world. ”

Niseya nodded, indicating that he understood what Chu Tianjiang meant.

Of course, Chu Tianjiang said that at this point, it would be difficult for Niseya to continue, and it was impossible for him to directly inquire about the method of controlling the star core.

The entrance to the Underground Realm is in the middle of the city, and it is also the headquarters of the imperial authorities' troops in the city.

Before arriving, Chu Tianjiang changed into a set of imperial army uniforms that Nisea had prepared for him, and Kistis and Lyphia also changed into the same uniforms.

Next, everything went smoothly.

Niseya seemed to know the commander of the garrison here, at least somehow got the pass, and took Chu Tianjiang and them into the barracks without danger.

The entrance, in fact, is a passage that leads straight to the bottom.

According to Nishea's explanation, in this passage, the superpowers of the qualitative people will not only not be weakened, but will be enhanced.

Of course, there are several elevators in the passage, so you don't need to use superpowers.

Niseya also only sent Chu Tianjiang and them to the top of the elevator, and according to him, when they reached the bottom of the passage, they would pass through a checkpoint. Because Chu Tianjiang held a pass issued by the Imperial Authorities, the guards at the checkpoint would think that they were sent by the Imperial Authorities, and they would not embarrass them. After entering the Underground World Realm, Chu Tianjiang had to rely on himself, and Nisaia didn't know the situation there.

Before leaving, Niseya didn't say much, after all, there were many imperial personnel nearby, and it was inconvenient to talk.

The elevator is large, but it runs very smoothly. It is not electricity or other energy sources that keep the elevator running, but the special properties of the mass energy body itself. Of course, inside the passage, Chu Tianjiang could clearly feel that his superpowers had indeed been significantly enhanced.

It took about half an hour before the elevator stopped.

According to Chu Tianjiang's estimates, the elevator went down at least thirty kilometers. If the thickness of the crust here is twenty kilometers, then at the time of stopping, the lifter is already under the crust, inside the mantle. In other words, the ascending body is in a liquid world.

Of course, the temperature and pressure in this world are very high.

It is precisely because of this that those who can survive in the underground world must be qualitative people, and they also need powerful superpowers, and it is impossible for ordinary people to survive in this environment.

Chu Tianjiang also had a suspicion.

That is, the powerful field that suppresses the mass energy body is generated by the single-celled life that envelops the earth, so the mass energy person is also suppressed inside the earth.

The problem was that when the elevator stopped, Chu Tianjiang's superpower did not weaken.

Kisstis and Lyfia had similar doubts, and they were nervous.

Perhaps, the suppression range of the strong field is limited and cannot act under the earth's crust.

As Nisea had said, the exit of the elevator was a checkpoint, and it was hermetically sealed and guarded by several Imperial personnel.

It is clear that they are all military and also armed with weapons.

What surprised Chu Tianjiang a little was that they were not checking the identities of Chu Tianjiang and the other three, but measuring their superpowers through an instrument. The instrument does not show the strength of superpowers, but only distinguishes between green and red, and can only pass through when it reaches the green zone.

Fortunately, Chu Tianjiang and the three of them all reached the green zone with their superpowers.

Obviously, this is the reason why Niseya asked Chu Tianjiang to enhance their superpowers. If you don't have powerful superpowers, even if you have a disguised identity, you won't be able to enter the underground world.

Of course, this also made Chu Tianjiang realize that the Underground World Realm was definitely different from the other two World Realms.

Perhaps, this is not a world realm at all, just an area, or a huge mine, where people are mining star cores.

This is also understandable, after all, there is no reason for the Empire to build an entire world realm in the interior of the earth.

You must know that the Air World Realm is already huge enough, with 300 billion inhabitants more than any period in human history, and there is an even larger Space Realm, even compared to the original invaders, in addition to the limitations in space technology, the current human civilization is not weak at all. No matter what Gramm's ultimate goal was, the huge Air World Realm and Space World Realm were enough for him to achieve his goal. Even if Gram needed a larger human civilization, he should use the terrestrial realm and even develop neighboring planets. At least from a technical point of view, it is easier to develop the Moon and Mars than to establish an entire underground world with hundreds of billions of people.

Of course, from a security point of view, colonizing outer space is also more desirable than exploiting the Underworld.

The existence of the Underground World Realm is mainly for the purpose of mining star cores. If the information provided by Iska is not wrong, the Imperial authorities have already mined the star core on the Moon, and there is no star core on Mars, so the Imperial Authority can only make a fuss on Earth and mine the Earth's star core.

Of course, it is also possible that the Imperial authorities will use the Underground Realm to hide a secret.

Through that long corridor, when he came to the airtight door, Chu Tianjiang stopped.

If the previous speculation is correct, then behind this airtight door made of mass energy bodies should be a high-temperature and high-pressure epoch realm composed entirely of liquid lava.

It's just that when the airtight door opened, Chu Tianjiang realized that his guess was not only wrong, but also ridiculously wrong.

Looking at the world realm unfolding in front of him, not only Chu Tianjiang was stunned, but even Kisstis and Lyphia were also stunned, and the three of them couldn't believe their eyes.

The Underground World Realm is not only a huge Realm of the World, but also a developed Realm of the World, a realm that Chu Tianjiang has never thought of at all.

The Empire did not hide secrets here, for the Underworld Realm itself was the greatest secret.
