The twelve True Palaces were created by twelve great beings, and the reason why they left the only key in the world inside the twelve True Palaces is very simple.
That is the prison specially built for the Peerless Daoist. It cannot be opened from the inside. To open it, you can only start from the outside.
However, due to the limitations of his magic, the Peerless Daoist was unable to leave the area where the barrier was located.
Insignificant cultivators would have no chance of finding the entrance to this place.
This means that as long as the key is left in the Twelve True Palaces forever, the possibility of the Peerless Daoist breaking free of his cage and wreaking havoc on the world again will be greatly reduced.
However, this does not mean that the Peerless Daoist will obediently stay in the cage and let others do as they please.
Lin Yu could imagine that the key should not have originally been in Wushuang Daoren's hands at all; he must have found the key through some means.
Perhaps it's through the search of the Lineage, or perhaps through some other method.
A tiny key may indeed be hard to find, but the Peerless Daoist has been here for hundreds of years.
Given such a long period of time, finding even the smallest key would not be a difficult task.
"Actually, those twelve powerful beings didn't leave the key where Wushuang Daoist was initially located, but rather on the other side where the Twelve True Palaces are located."
"But I can imagine that after so many years, that Peerless Daoist should have already found the key." The Longevity Daoist finished speaking with a hint of melancholy.
After listening, Lin Yu nodded. He understood why the Longevity Daoist had hesitated to tell him this matter several times.
The Twelve True Palaces Prison itself is impregnable, but if others were to learn that a special key exists within this vast prison, its stability would be greatly weakened.
"I believe that when those twelve imprisoned the Peerless Daoist here, they must have realized that with the Peerless Daoist's abilities, he definitely had a way to obtain the key from the outside."
"However, they must have already considered this day. Since those twelve seniors were willing to sacrifice their lives to seal the Peerless Daoist, it means that neither side is an ordinary person."
"What does it matter if this key is in the hands of the Peerless Daoist? He himself cannot escape, and those involved with him will also be unable to get out."
Lin Yu comforted the Longevity Daoist.
Upon hearing this, Daoist Changshou nodded repeatedly. "Even if Daoist Wushuang wanted to have someone bring the key out from the other side of the Twelve True Palaces and open the prison from the outside, I'm afraid it wouldn't be such an easy task."
"But you can come and go freely here. Since the Peerless Daoist brought you to such a secluded place, it means he intends to use you to escape from here."
"Didn't he give you anything when you left him?"
In fact, the Daoist of Longevity believed that the key was the most important thing.
Although the Longevity Daoist did not believe that such an exquisite prison as the Twelve True Palaces could be opened by a cultivator like Lin Yu, even if Lin Yu was the true "chosen one," it would definitely not be an easy task to open it.
But for the Peerless Daoist, Lin Yu was his only hope for thousands of years.
He could not give up on the first cultivator to stand before him in the past thousand years. The Longevity Daoist was convinced that as long as the key was in the hands of the Peerless Daoist, he would definitely hand it over to Lin Yu.
However, Lin Yu's hands were empty; there was no trace of the key at all.
"Senior, when I left the Twelve True Palaces on the other side, I really didn't hear about any secret keys or anything like that," Lin Yu said.
"That can only mean that we haven't mastered the key, and it might still be hidden in some secret corner of the Twelve True Palaces." After saying this, the Longevity Daoist looked at Lin Yu with expectant eyes.
Lin Yu felt helpless. When he left the Twelve True Palaces on the other side, the Peerless Daoist only told him to go to the center of the Dharma Gate, and then didn't say anything else.
Let alone the key, even the peerless Daoist priest didn't give him any rare treasures.
However, seeing the expectant look on Changshou Daoren's face, Lin Yu felt extremely embarrassed.
"Senior, you don't actually think I've already obtained the key, but are deliberately not handing it over, do you?"
"Actually, I've met Master Wushuang twice in a sense, but I haven't even seen a trace of the key."
"The Peerless Daoist didn't give me anything at all. He only told me the location of the Twelve True Palaces' method and told me to quickly clear all the obstacles near the method and rescue the cultivator I wanted to save."
"Besides that, the Peerless Daoist didn't give any other explanation."
Lin Yu said helplessly.
In his view, the Peerless Daoist was unfathomable, and someone like him would never trust a cultivator like Lin Yu whom he had only met once.
"Perhaps the Peerless Daoist does indeed possess the key, but for someone like him, a key isn't something he can just casually hand over. Perhaps he has other uses for it."
"No, if the Peerless Daoist wants to leave the Twelve True Palaces, he must give you the key."
"Because apart from the key, no cultivator connected to the Peerless Daoist, nor even the Daoist himself, can easily leave this prison, let alone fundamentally dismantle it."
"Since you said that Master Wushuang didn't tell you anything when he left, then that just means he hasn't found the location of the key yet."
Seeing that Lin Yu seemed genuinely unaware of anything related to the key, the Longevity Daoist had no choice but to say the same thing.
"To leave here, you'll need a key. It may sound a bit long-winded, but I still want to remind you that if you encounter him again in the future, you must never completely trust him; you should always remain suspicious."
"After all, Fellow Daoist, your status is special, and you are the only cultivator in thousands of years to have faced him face-to-face... I think the Peerless Daoist will definitely not let you off so easily. Although I don't know how he did it, I'm sure he used some trick on you!"
"You must firmly uphold your beliefs and not let this Peerless Daoist go out to harm the world and bring disaster to the people!" the Longevity Daoist said righteously.
Lin Yu nodded. The things that the Longevity Daoist had instructed him on were all very important, and he certainly couldn't be careless in the slightest.
