It seemed that this was what attracted the fireflies, but because it looked so inconspicuous, he didn't find it when he searched around during the day.

The appearance of this stone here must not be accidental, I am afraid that Dongfang Rui threw it here, and he only needs to wait until the evening to find the way up the mountain.

Su Qiubai carefully put the stone in his arms and walked towards the path. The fireflies around him also flew forward with him, and they happened to help him light the way forward along the way.

After walking a distance, there were fewer and fewer fireflies around him, and it seemed that the fragrance of the stones gradually faded after he put them away.

This is just right, lest he carry a cloud of green light wherever he goes, and if someone from Taiyi Gate passes by, he will be found from a distance.

There were no obstacles along the way, and there were too many traps on the road ahead, plus this most difficult Qimen formation, if it weren't for the guidance of Dongfang Rui, an "insider", even Su Qiubai, a person who was proficient in countless Qimen formations, would not be able to crack it.

Su Qiubai walked cautiously for a long time, but he didn't go far away, because it was night, and he had to be careful to restrain his tracks, so his speed was naturally much slower.

When he saw the big stone tablet with the word "Taiyi" written on it, it was already early in the morning.

There is a stone staircase that winds up behind the stele, and you must be able to see the mountain gate that enters the Taiyi Gate if you go further.

Su Qiubai naturally didn't dare to take the main road, but walked slowly up the mountain road not far from the stone steps.

Ever since he was sensible, he had the idea of rescuing his mother, but in the past, it was almost just a dream for him. Since meeting Dongfang Rui, this dream has begun to become clear, and it is no longer as unattainable as before. But until he entered Changbai Mountain with Dongfang Rui, there was no real joy in his heart.

But at this time, when he saw the stone tablet of Taiyi Gate, he suddenly realized that his long-cherished wish for many years was close at hand.

Suppressing the excitement in his heart, Su Qiubai continued to carefully touch the mountain, and half an hour later, he saw the mountain gate of Taiyi Gate.

On both sides of the mountain gate are two long walls, enclosing the entire Taiyi Gate in the middle. There were two disciples standing vigil at the door, but their Taoism was not enough, and they couldn't find Su Qiubai hidden in the night.

Going around to the wall behind the mountain gate, Su Qiubai used his divine sense to detect that there was no one behind the wall here.

Climbing over the tall wall, Su Qiubai immediately went around to the back of a hut, and waited until there was no movement before he came out to inspect.

At this time, it was already late at night, and all the disciples in the door were already asleep, only a few disciples were still keeping vigil, but presumably there would never be outsiders on this mountain, so those vigil disciples were very lax, and most of them found comfortable places to sit and doze off, this defense was completely useless, and Su Qiubai easily bypassed their sight.

The top priority at the moment is to find his mother and Dongfang Rui, who is a disciple of Taiyimen, and I am afraid that she is only under house arrest, and may not be imprisoned. But Dongfang Rui is different, he left Taiyimen with infamy back then, and he was considered a defector disciple, but now he has been arrested and imprisoned, and it is light to be imprisoned, if someone deliberately frames him, it is possible to kill him.

Although Su Qiubai was very anxious to rescue his mother, his mother was not in danger after all, so he still decided to find Dongfang Rui first.

Regarding the terrain structure of Taiyi Gate, Su Qiubai's eyes were completely black, and it was late at night, and it was dark everywhere, so it would take him a lot of work to find it.

After looking for a long time, but found nothing, time passed minute by minute, if he waited until dawn, Dongfang Rui was likely to be disposed of, so he had to do his best to find him.

After thinking about it, Su Qiubai decided to take a risk.

"The prisoner has escaped! Come on! Su Qiubai found a place where no one was and shouted loudly.

Since there was no one around the place where he was, there was no need to worry about being discovered, and after shouting, Su Qiubai hid in the dark again, listening carefully to the movements around him.

Soon, there was a commotion in the originally silent night, except for the disciples who were keeping vigil, many other disciples were alarmed, and they were all running in one direction, Su Qiubai knew that it must be the place where the prisoners were held, so he also quietly followed.

Because the structure of Taiyi Gate is built against the mountain, all the houses are built in a staggered manner following the trend of the mountain, and if an architect sees these houses, he will be surprised by the construction techniques of the ancients.

And the place where the prisoners were held was a cave carved out directly from the mountain, and the door was also delicately camouflaged, if it wasn't for those disciples, it would be difficult for Su Qiubai to find here.

The disciples who were awakened went into the cell to check around, and they all walked out with blank faces, and some people even complained: "Who is idle and bored in the middle of the night? The prisoners are all here well, what are they yelling about? ”

"Hu Tieshan, you like pranks the most, did you do it again? Isn't it your turn to keep vigil, to wake us all up and accompany you? The other disciple complained by name.

"Don't talk nonsense, I slept soundly just now, how can I have the kung fu to amuse you?" Hu Tieshan retorted.

"Okay, you, sleep during the vigil, let me catch the handle now, I'll sue Uncle Song tomorrow!" The disciple said with a smile.

"You come less! It's like you're keeping a vigil and not sleeping! Hu Tieshan said angrily.

After going back and forth, the topic was pulled away, and when the disciples saw that the prisoners were all here, they also put their minds at ease, and they all went back to their rooms and kept vigils, and they left after a while.

Su Qiubai waited until the surroundings were quiet again, then went around to the location of the cell door, and according to the disciple just now, he groped on the mountain wall for a long time, and finally found the hidden mechanism, and after a twist, the cell door opened in response.

Because this cell was relatively hidden, so there were no guards of disciples, Su Qiubai was cautious at first, but soon found that there were not many people in it at all, and all of them were prisoners, so he let go of his courage and strode forward.

Originally, the other prisoners were asleep, but after the commotion just now, they had all woken up, and at this moment, when they saw Su Qiubai swaggering in, they all gathered around curiously. Because most of them were imprisoned after their disciples made mistakes, and they were still relatively familiar with their fellow disciples, suddenly such a naïve person, still wearing outer clothes, someone asked, "Who are you?" Why haven't you seen it before? ”

Su Qiubai glanced at the man, hesitating whether to make up a lie, but after hesitating for a while, he still didn't speak, but walked directly to the door of Dongfang Rui's prison and shouted softly: "Uncle cousin!" ”

Dongfang Rui originally didn't have any interest in the previous movement, and had been resting in the corner, when he heard Su Qiubai's voice, he immediately came over and said, "You kid is really smart, I know that you will definitely be able to find my tips to go up the mountain!" ”

Su Qiubai lowered his head and studied the door lock, and said, "Those will talk about it later, find a way to open this door lock first, otherwise it will be troublesome if someone comes in a while." ”

Dongfang Rui said: "It's useless for you to unlock this lock, there is an enchantment outside this cell, you have to go inside to find the mechanism to unlock the enchantment, and I can come out." ”

Su Qiubai nodded, turned his head and continued to walk deeper into the cell. When he reached the bottom of the hallway, he was dumbfounded.

There is a huge disc on the wall with many squares inlaid with intricate tracks underneath. Although I don't know what the principle of this thing is, it is obviously the mechanism that controls the prison door.

Not to mention whether he knew how to unravel this thing, it was a bit troublesome to identify which piece corresponded to the cell door where Dongfang Rui was.

Su Qiubai took a closer look and found that each small square was engraved with extremely fine lines, which seemed to be a puzzle that had been dismantled in comparison.

According to common sense, putting a puzzle here means that the puzzle can open the prison door, but there is only one puzzle piece, which prison door will be opened? Or do you just put together the pieces and all the doors will open?

Su Qiubai hesitated for a long time, but he still didn't dare to start, in case of some accident, his previous efforts would be in vain.

After thinking for a while, Su Qiubai still walked back to Dongfang Rui's prison door and asked, "Uncle Cousin, how to solve the mechanism on the wall?" ”

Dongfang Rui glared at him and said, "You ran away before I finished my words just now, I can't stop screaming." The mechanism on the wall is a puzzle, but this puzzle is very special, the same pieces can be put together with different patterns. And different patterns correspond to different prison doors. ”

"And what pattern does this cell correspond to?" Su Qiubai asked eagerly.

Dongfang Rui shook his head and said, "I don't know, only the disciples in charge of guarding the cell know about these contents, otherwise wouldn't it be bad if someone sneaked in here and released the prisoners?" ”

Su Qiubai was suddenly worried, even he didn't know, so how to unravel this mechanism?

"Just try them one by one, there's nothing else you can do." Su Qiubai gritted his teeth and said.

"No! There are still a lot of people in this cell, and we don't know who they are, and if there are the most vicious people, I am afraid that it will be a big mistake to let them go. Dongfang Rui hurriedly stopped.

Su Qiubai frowned: "Then what should I do?" ”

Dongfang Rui turned his head and glanced out, and finally had to say: "It's really not good, you just go first, presumably with your strength, it will not be difficult to rescue your mother." ”

Su Qiubai hurriedly shook his head: "Then how can it be done?" The people who framed you back now see you back, and most of them will harm you in order to cover up your crimes, and if you don't get them out today, tomorrow you will be in danger. ”
