Gradually, gradually, Mo Li followed the strange sound with extremely light steps, and finally came to the bookshelf that she had searched many times just now.

Attached to the wall, Mo Li listened carefully......

Vaguely, someone seemed to be whispering inside the wall, but because it was too far away and a wall was added, Mo Li couldn't hear the content of the words at all.

If something goes wrong, there must be a demon!

Who is the one who speaks within this wall? What is he or they talking about?

Mo Li only thought about it for a moment, and then made a decisive decision in an instant.

This trip was so fruitless, and I really felt aggrieved in my heart, if I could inadvertently find out the secrets of the existence of this heart cultivation hall...... Then she is also a worthwhile trip!

Now that he had made up his mind, Mo Li didn't hesitate any longer, and the direction of his search instantly shifted from the beginning of the search for Wuji Dan to the search for differences around the bookshelf.

Experience told her that there must be a secret door in the wall behind this bookshelf, and since it is a secret door, there must be a mechanism to open the secret door, as for this mechanism......

Mo Li began to look around with the bookshelf as the center, looking for a possible place to place the institution.

She had also read a lot of books and codex on the formation of the mechanism, and generally speaking, the place where the mechanism was placed was usually the least noticeable or the most inconspicuous place, and the usual place was often placed right under her nose.

The so-called darkness under the lamp is this truth, but this kind of little trick has no effect on Mo Li......

Since he had already searched most of the places just now, it didn't take much time for Mo Li to successfully find the location of the mechanism that opened the secret door.

As Mo Li had guessed before, the mechanism that opened the secret door was not far from the bookshelves, an extremely inconspicuous gilt pen holder placed on the table.

Mo Li leaned over and gently rotated the pen holder with his hand for a few weeks.

Thundered~

A deep voice came out as Mo Li swirled, and soon, the entrance to a secret door appeared in front of Mo Li's eyes.

Just in case, Mo Li first approached the secret door slightly, and then poked his probe in, checking if there were any other mechanisms, but his eyes didn't see how far he was obscured by a turn in the stone path.

Even so, the corners of Mo Li's long-thinking mouth still outlined a slight arc, and then without much hesitation, he dodged and entered the secret door.

……

After entering the secret door, a slightly narrow stone passage immediately appeared.

As the lord of a country, Mu Zhengyun, who is usually above 10,000 people, is afraid that he will condescend to others this time.

Compared to the extravagant stone path of Guiyun Mountain Villa, which is dotted with thousands of night pearls, the stone path of the Heart Cultivation Hall is illuminated by the candles of burning candles.

Unlike Guiyun Villa, the stone path of the Heart Cultivation Hall is very short, but the temperature around it is much lower than before with each step.

"Could it be that this Heart Cultivation Hall also has an ice room that is the same as Guiyun Mountain Villa?" Mo Li thought secretly in his heart.

Soon, barely waiting for Mo Li to walk a few steps, he walked into a relatively spacious stone room.

Looking up, the stone chamber was filled with large and small ice cubes, and it was obvious that this was an ice chamber.

"I was really blinded by me, this dark room is really an ice room!" The corners of Mo Li's mouth twitched slightly, secretly admiring himself.

"It's just ......"

It's just an ice house, why build it so secretively? Could it be that there is some ulterior secret here?!

Thinking so, he then walked on, but ......

Mo Li's front feet into the ice room had just been lifted and had not yet landed, and he hadn't even had time to observe the environment in the stone room, when he entered the door, he noticed Mu Zhengyun in the center of the ice room at first glance.

At this time, Mu Zhengyun leaned over slightly and lay on the ice coffin, as if he was whispering something to himself to the ice coffin.

Because Mu Zhengyun's voice was too soft, Mo Li couldn't hear it very clearly, but Mu Zhengyun's appearance at the moment Mo Li could see it very clearly.

Compared with Mu Zhengyun in his impression, he has lost the emperor's coat at this moment, and the extremely serious and non-enterable momentum on his face on weekdays has all disappeared, and the expression on his face at this moment is full of kindness and vicissitudes.

Mu Zhengyun, who had the same gray hair, the same wrinkles, and plain clothes, was almost no different from those ordinary old people in the market, and even more old and twilight than those people.

Seeing Mu Zhengyun in the stone room, although Mo Li was shocked, he quickly calmed down.

Really! I just heard someone talking in the dark room, all this was really not her illusion, but even if she had a guess in her heart, when she really saw Mu Zhengyun, Mo Li's heart was still a little surprised.

At this time, Mu Zhengyun, who was taking care of himself and the rise of "chatting" with the ice coffin, did not notice that there was another person in the stone room, and was still talking about something to the ice coffin.

Inevitably exposing her tracks, and in order to hear more clearly, Mo Li began to look for any place near the ice coffin where she could hide her figure.

Quickly looked around the stone chamber, originally looking for a place to hide, but accidentally made a surprising discovery......

It was this sudden unexpected discovery that almost made the calm Mo Li cry out in surprise!

What kind of wind and waves she has never seen? But that's too ...... Too......

What a coincidence, right?!

Mo Li covered his mouth desperately, afraid that he couldn't help but make some noise for a while, in case Mu Zhengyun found out, everything he had done before would be wasted.

But......

Even if he couldn't make a sound, the excitement in Mo Li's heart at this moment was incomprehensible.

In front of me, it can be said that every stone and tree in the ice room is constantly and strongly stimulating Moli's heart.

The ice room in the Heart Cultivation Hall turned out to be exactly the same as the structure of the ice room of Guiyun Mountain Villa, and the two ice rooms were almost identical, even ......

Is it a coincidence that even the ice coffin in the ice chamber is exactly the same?

Could there be such a coincidence in the world? No! Mo Li said that she was the first to disbelieve it.

Not to mention that the ice room of Guiyun Villa was designed and built by his grandfather without any appearance, and it did not go through the hands of a second person at all, after the ice room was built, even a handful of people knew that there was an ice house in Guiyun Villa, not to mention that someone could imitate an identical ice house.

And......

Mo Li moved his steps lightly, and then came to a stone wall with a slightly special structure around it, and then gently pressed his palm on it......
