At this time, it is the end of the fourth watch, and at the beginning of the fifth watch, this time should be the time when people are asleep, and this courtyard is where the master of the door and some high-ranking disciples in the door live, and there are no disciples who patrol the night to patrol nearby. Who could be that strange person just now?

Wu Zhiyuan groaned slightly, and went straight to the corridor on the side, wanting to see the identity of the person just now.

When Wu Zhiyuan saw that person, he had already walked to the end of the corridor and entered another passage, Wu Zhiyuan didn't know if he could catch up with him, so he walked a few steps briskly, trying to keep his footsteps low.

At the end of the corridor was a passage to other places, Wu Zhiyuan was not familiar with this courtyard when he first arrived at this courtyard, so he hesitated for a moment and walked straight towards the passage.

This passage is a flower vine channel, the left and right sides and the top of the head are covered with flower vines, the vines are the same thickness, but this season the flowers and leaves have already fallen, only the bare vines are intertwined with each other, teeth and claws, looking ghostly.

There was only one turn in this flower and vine passage, Wu Zhiyuan chased all the way down, and did not find any trace of the person, according to the way he walked when he first saw the person, his walking speed should not be fast, but he didn't catch up at this time, which is really a bit puzzling.

Chased until the end of the passage of flowers and vines, there was a small yard in front of me, the courtyard was very clean, there were no trees to furnish, three sides were rocks, it can be seen that it was built by digging the mountain, but it took so much effort to chisel out such a yard, it seems to be a bit too wasteful.

Wu Zhiyuan glanced at the courtyard and found nothing abnormal, at this moment, there was a sudden sound of "rustling" from the place where the vines spread not far from the right hand, he was taken aback, thinking that there were wolves, insects, tigers and leopards, but he heard the sound of "rustling" suddenly disappeared, followed by the sound of vines breaking.

Wu Zhiyuan was shocked in his heart, the vines of this flower vine are about the thickness of a child's wrist, and they are obviously some years old, plus the vines have not dried up, and they have a certain degree of toughness, it is extremely difficult to break them with their bare hands, so what will break the vines at this time?

I couldn't help but look in the direction where the sound came from, and I saw that the vine trembled slightly, and a person suddenly walked out of the vine.

Wu Zhiyuan fixed his eyes and saw that this person was the person he had just seen flashing away at the end of the corridor.

"Stop!" Wu Zhiyuan shouted loudly.

After the man came out of the vine, he didn't seem to see Wu Zhiyuan's existence at all, and he also turned a deaf ear to Wu Zhiyuan's drinking, and walked straight towards the stone wall diagonally opposite.

Wu Zhiyuan was unarmed at this time, the Blood Shadow Demon Knife and the Peach Wood Sword were both placed in the room, and this person was unknown, Wu Zhiyuan didn't dare to conflict with him rashly, so he had to shout again, but the person still didn't react, and walked to the stone wall in a blink of an eye.

A scene that made Wu Zhiyuan unbelievable happened, only to see that the man didn't seem to see the stone wall at all, he didn't stop at all, and continued to walk towards the stone wall, and at the moment when he was about to hit the stone wall, he suddenly disappeared.

The mountain ghost was born from the mountain, it can come and go freely in the mountain, after coming out of the Cixi underground palace before, Wu Zhiyuan had chased the mountain ghost attached to Li Lanru's body, but in the end it fell short because of the sudden appearance of the moon shadow Fuxian, so that the mountain ghost took the opportunity to hide in the mountain rocks. Wu Zhiyuan still remembered that incident vividly, and when he saw a similar situation again at this time, he couldn't help but start to suspect that the person just now was also a mountain ghost?

With this question in mind, Wu Zhiyuan also walked slowly to the stone wall, he walked to the position where the person was standing just now, and immediately understood the reason why the person suddenly disappeared in front of the stone wall. I saw that there was a secret door under the stone wall, and the secret door was about more than one person high, but the upper part was set above the ground, and the lower part was set below the ground, which was a combination of a door and a hole in the ground.

There was an iron door on the secret door, and the iron door was open at this time, and the man must have entered this secret door just now. Wu Zhiyuan took a closer look and found that the stone wall above the secret door was carved with three clear characters: Ten Thousand Gu Palace!

"Carry this girl to the Ten Thousand Gu Hall first, and I'll detoxify her later." At this time, Wu Zhiyuan's mind recalled a sentence that Jin Zhuni had said in the Black Descendant Gate Hall, when Jin Zhuni ordered Hei Lao Liu to carry Wen Qing to a place, and the name was Wan Gu Palace.

"It seems that warmth has been placed here." Wu Zhiyuan secretly thought in his heart, the person behaved strangely just now, his identity was still a mystery, and in addition, Wu Zhiyuan also wanted to see how Wen Qing's corpse poison was resolved, so he didn't hesitate any longer, and leaned over and got into the secret door.

Inside is a slanted downward step, there is no light around, it is pitch black, Wu Zhiyuan holds the stone wall in his hand, carefully picks up the steps and goes down, fortunately this step is not long, and soon he walked to the bottom of the steps, and then the direction of the passage turned to the right, and a flat passage appeared, there is a light trough every few meters on the stone wall of the passage, and there is an oil lamp in it, all of which are quite bright.

Wu Zhiyuan walked all the way to the end of the passage and found a stone door, the stone door was hidden, and there was a bright light leaking out inside, and the light inside was brighter than in this passage.

Wu Zhiyuan's heart moved, stretched out his hand to gently push the stone door, only to hear a few "rumbling" low sounds, the stone door opened, Wu Zhiyuan looked inside, and saw a woman in lace black clothes with her back to him, her hands on the stone bed upside down something, and there was a person lying on the stone bed, it was Wen Qing.

The woman seemed to hear the sound of the stone door, turned around slowly, and before Wu Zhiyuan could speak, she said in surprise: "It's so late, why didn't the door master rest and came here?" ”

Wu Zhiyuan looked at her with eyes, and couldn't help but be stunned, this person in front of him was Jin Zhuni, looking at the situation, she was detoxifying Wen Qing.

"I ...... I heard a noise just now, and I saw a person who was acting suspiciously, and followed him all the way here, did you hear any movement? Wu Zhiyuan could only answer like this, he couldn't say that he was here to check on Wen Qing's situation, otherwise he would appear to be distrusting Jin Zhuni.

"No, I've been here since I came back from the main hall to detoxify this girl, and I haven't heard any movement." Jin Zhuni said with a little surprise.

Wu Zhiyuan nodded, and looked around at the same time, this stone room was very large, but it was very empty, except for five or six stone beds on each side, there were almost no other furnishings, I don't know where the name of this Ten Thousand Gu Hall came from.

Wu Zhiyuan was suspicious in his heart, he obviously saw that person who behaved strangely walked into the secret door of this Ten Thousand Gu Palace, and there was only one passage in this secret door, how could he not find any trace of that person? Just when he thought that there was indeed no trace, his eyes suddenly caught a glimpse of a large porcelain jar placed in the corner of the wall on the side, which was almost the same size as the large porcelain jar that Hei Lao Liu carried on his shoulder, but it was obviously not the same, because this large porcelain jar looked more dilapidated, and the surface had begun to peel off.

"What's in that jar?" Wu Zhiyuan pointed to the large porcelain jar in the corner of the wall and asked.
