After listening to Zhiyun's narration, Shanhe's heart was followed by a secret sigh.

If this tower is really the strongest defense of Nangong Gate as Zhi Yun said, then with his ability, it will definitely be impossible to storm the tower.

If you want to rescue your senior sister, it seems that you can only outwit it.

"Wow, it turns out that the Zhenling Tower is so powerful......? Senior brother, what is this tower for?"

"According to records, Dong Kuo's predecessors built this tower to suppress a terrifying demon beast. As for what kind of monster this monster is, and how powerful it is, I don't know very well. But judging by the sturdiness of this tower, it's not hard to guess that this guy must be very scary. ”

After listening to Zhiyun's speculation, Shanhe nodded as if he didn't understand. After sweeping the garbage outside the house, he pretended to be curious and asked again:

"Senior brother, what happened later? Is the demon beast dead? It won't be so long, and it's still locked up in the tower, right?"

Hearing this, Zhi Yun immediately laughed:

"Hehe, of course I'm dead a long time ago! It's been more than a thousand years, how can any demon beast live for so long?"

"Oh! yes. Hehe, I'm stupid again. After smiling awkwardly, he listened to Shanhe and ask, "Then now...... Is there anything else in the tower?"

"Well, since the death of that demon beast, this Zhenling Pagoda has been transformed into the highest-level prison in our Nangong Gate. It is used to hold some very important prisoners, and it belongs to the sect and is never open to the public. So, don't come near anything if you find out, you will be severely fined!"

Hearing this, the origin of this ancient tower was finally clarified.

Seeing that his senior brother was quite easy to speak, he was not defensive against himself. After pondering for a while, Shanhe planned to ask about the gate of the Zhenling Pagoda again.

I remember that when he infiltrated the Nangong Gate in the form of a bird that night, he saw Han Yi open three gates before entering the tower, and each gate opened in a different way. If he wants to rescue his senior sister, he must master the opening methods of these gates in detail.

But before he could speak, he was stopped by Xiao Bang's words:

"Master, if I were you, I would never ask the other party about the way to open the prison door on the first day of apprenticeship. Your senior brother has said many times just now that this tower is an important place for the sect to be avoided. But after you asked about the origin, you chased and asked how to enter, doesn't this make people suspicious?"

Seeing that Shanhe was hesitant, he listened to Xiao Bang and continued:

"Besides, it's not that I look down on you, this senior brother, even if he is the head of the sect, he may not know how to open this door. Even if he really knew about such a confidential matter, do you think he would tell you on the first day he met you? Master, it's still the same old saying, you can't eat hot tofu in a hurry. Now that you've chosen to lurk here, you've got to hold your breath! Otherwise, within a few days, you'll be exposed. ”

After listening to Xiaobang's persuasion, although Shanhe was unwilling, he understood that the other party's words were reasonable, so he had to stop for the time being and didn't ask any more.

But after thinking about it, didn't many of the owners of the little bracelet come from Nangong Gate? Then would she know how to open the door? Then she asked.

Soon, I heard the little bracelet reply:

"Master, if I knew, I would have told you a long time ago, why wait until now? You are right, I have many masters from Nangong Gate before, and several of them know how to open this door, but ...... Only in that era. ”

"What did you mean?"

"In order to prevent the enemy from discovering how to open the Spirit Tower, the secret method of opening the door is changed every ten years. Just as it is the same thing that you change the password in the secular world, the method of opening it is not set in stone. So, although I have more than a dozen ways to open the door in my memory, those are all old and have long expired. I don't know how to open it. ”

"Oh, so that's the case? This senior Dong is really powerful, as early as thousands of years ago, he could think of using the method of changing the 'password' to prevent theft, and his thinking is too avant-garde, right?"

"Hehe, about this, it's really not Dong Kuo's idea!" After smiling, Xiao Bang explained the origin of the method to Shanhe......

About 200 years ago, because there had never been an accident before, the Zhenling Pagoda has been following the law of opening the door thousands of years ago.

Until one day, a prisoner actually escaped from the Zhenling Tower, which is known as the 'strongest defense'!

As soon as this incident came out, it immediately caused a sensation on the upper floor of Nangong Gate.

The reason for the sensation is not that this prisoner is terrible or how serious the consequences are, but that no one knows how he escaped from the tower!

In order to find out about this matter, it took Nangongmen many years to recapture this person.

After some torture, the reason was finally figured out.

It turned out that the reason why he was able to escape from this tower was because there was a spy inside the Nangong Gate. It was this spy who let the prisoner go.

But after careful investigation, although this spy is a disciple of Nangong Gate, his status is very low, and it stands to reason that it is impossible to know how the door was opened.

Not to mention him, even his master, or his master's master, could not have known such a high-level secret.

Later, through all-out investigation from all sides, I finally found the truth of the matter: it turned out that this spy learned the secret method of opening the door from his own family!

As early as more than 1,000 years ago, when this tower was built, many skilled craftsmen were involved in the design and construction of the Zhenling Tower.

Originally, the main purpose of this tower was to suppress monsters, not prisons.

Therefore, the secret method of opening the gate was not as strict as it is today, and many craftsmen and disciples involved in the construction knew about it.

In addition, as early as a thousand years ago, it was a great honor for many craftsmen to participate in such a majestic project.

Therefore, including the secret method of opening the gate, all the legends about the Zhenling Pagoda have been passed down from generation to generation by their descendants.

And this spy happened to be the descendant of one of the craftsmen, so he mastered the secret of opening the door.

After finding out the ins and outs of the case, the head of the case at the time immediately realized the seriousness of the matter and immediately demanded that the way the door was opened be redesigned.

In addition, in order to prevent similar incidents from happening again, there is also a special rule that the "door lock" must be changed every ten years to reduce the chance of leakage.

To this day, this rule still exists.

Therefore, Xiao Bracelet, who has been dormant for more than fifty years and has just woken up, has a lot of secret methods for opening the door in her mind, but they have expired and cannot be used.

If you want to get the latest "password", I am afraid that you can only find a way from the current "high-level" of Nangongmen.
