If this Sky City City Lord hadn't panicked, a month here would have been almost a year on the ground.

I've been here for more than three months, doesn't that mean that three years have passed on the ground?!

Before, he may not have been too anxious, but after learning about this time mystery, Li Futu's mentality couldn't help but change instantly.

It is unimaginable that when he returned to the earthly world, he found that the vicissitudes of life had changed, and the people he knew and loved had become gray-haired.

While hopefully all this is just fake, why should the other person lie?

"Time becomes slow, but it also has its advantages, at least, although you are exiled here, as long as you are not killed, your life will be greatly extended, and everything has to be viewed dialectically, right?"

Sky City City Lord's words did make some sense, but Li Futu was naturally unwilling to obtain the so-called eternal immortality at the cost of staying here.

"Do you know a way to get out of here and go back to earth?"

He asked in a deep voice, his anxious emotions even uncontrollable in his tone.

"It's easy to go to hell, but if you want to escape from hell, it's not that simple, who doesn't want to go out here?"

Sky City Lord Erlai said calmly, and as he spoke, his hand stroking the mural slowly withdrew.

"By the way, I want to ask you a question, which is why I asked you to come. ”

He still had his back to Li Futu and did not turn around.

"How did you offend Atlantis so much that they didn't choose to kill you, but instead exiled you here?"

"I was not exiled. ”

Li Futu had a hunch that this Sky City Lord was likely to be the key factor in deciding whether he could escape from this underground world, so he didn't choose to hide it in front of the other party.

"I broke into Atlantis and stumbled into it. ”

"Huh"

"Mistaken?"

Sky City Lord Erlai smiled lightly, the meaning was incomprehensible, and then stopped, and after a moment, he turned to ask: "Atlantis, it should be a forbidden place in the earthly world, what are you doing in Atlantis?"

"Find a friend. ”

Li Futu explained briefly.

The Sky City City Lord didn't ask any more questions, looked at the vast mural, and said slowly: "If you really want to leave here, there are two ways. ”

"Please explain. ”

Li Futu said in a deep voice.

A month underground, a year above earth, and knowing this sensational fact, it was as if he could hear a voice every second that had passed.

"The first way, break through the extreme realm, then you can break the spatial barrier and travel between the two realms at will. ”

Li Futu was silent when he heard this.

The emperor and the emperor are exalted.

He still remembered the division of strength in the Lost Realm that Su Shi Yanran had introduced to him.

Although the people in this underground world are generally very strong, until now, he has also encountered the masters of the Emperor Realm, and the Zun Realm has only heard of it, as for the Extreme Realm

Until now, he had never heard of it.

Not to mention the existence of breaking through the extreme realm.

It's not that he is presumptuous, Li Futu is very clear, he is far from the realm of breaking the space barrier that the Sky City City Lord said, I don't know how many steps there are still to cross, even if he takes a step back and says, even if one day, he really reaches that realm, how many years will it be?

And at that time, how long did the earthly world pass?

"Are there people outside the Arc here?"

Li Futu asked.

Sky City's response from the City Lord Erlai was not unexpected.

"Not yet. ”

"What about the second option?"

"The second type"

Erlai smiled.

"That's waiting. ”

"Wait?"

Li Futu frowned.

"That's right, wait for the day when the eternal core will be destroyed. ”

Hearing this, Li Futu's brows furrowed even deeper.

Waiting for the destruction of the eternal core is almost equivalent to waiting for the destruction of this Lost Realm, and its difficulty is probably not much lower than breaking through the Extreme Realm.

The other party can be said to have told him two impossible ways to achieve it.

Is this deliberately making things difficult for him? Or is it teasing?

"Will the eternal nuclear be destroyed?"

Li Futu asked rhetorically.

But the other party's response was very unexpected.

"Of course, and it should be in the near future, so if you want to leave alone, I'm afraid you'll have to hurry. ”

Erlai's tone was meaningful.

Like him, Li Futu raised his head, stared silently at the vast and magnificent mural, and fell silent.

Not long after returning from the Tower of Babel, Su Shi Yanran came over, and it seemed that he had not rested, and had been waiting for him.

"Have you met the Sky City Lord?"

Li Futu nodded, as if he was preoccupied.

"What is he looking for you? Does he know you?"

"He just warned me to stay in the city and not cause trouble. ”

Su Shi Yanran didn't think much about it.

"I thought Zuma had said hello to him, and he was going to trouble you. ”

"How long has this Sky City been established?"

Li Futu asked suddenly.

"Why do you ask this?"

"Just ask. ”

"I don't remember this clearly, it's been a long time anyway, at least it was there when I was born. ”

"Has the eternal core ever been extinguished, or perhaps?"

Li Futu's questions are more and more bizarre than the other.

"What do you say?"

Su Shi Yanran looked at him strangely.

"If the Eternal Core is gone, won't everyone be dead?"

Li Futu didn't look at the fiery burning underground sun.

What Su Shi Yanran said is very right, the core of eternity is equivalent to the sun of the earthly world, and once the core of eternity is destroyed, the entire lost realm may have to be finished.

In that case, what did the Sky City City Lord mean by that?

On what basis did he assert that the Eternal Core would be destroyed soon?

"Still, I've seen a legend. ”

Su Shi Yanran's voice sounded again.

"What legend?"

Li Futu retracted his gaze and looked at Su Shi Yanran, and immediately asked.

"The core of eternity seems to have been extinguished for some time before. I don't know the specific reason, anyway, in those dark days, many people died, and that was the end of the world. ”

"How long ago do you mean before?"

Su Shi Yanran shook her head.

"I just glanced at it at the time, and the records in that book are not too detailed, if you are really interested in the city of Stone, I can help you look it up, but now it is in Sky City. ”

"If"

Li Futu spoke.

"In the near future, the end will come again?"

Su Shi Yan was stunned for a moment, then looked at the burning eternal core, and said disapprenorovingly: "What are you kidding, if that dark history really repeats itself, then neither of us can escape, let's wait for death together." ”
