Yun Fei couldn't help but breathe a long sigh of relief, and his heart was also horrified. If he walked slower and was trapped in the water by the spring, he would have frozen to death immediately if he didn't drown.

When he was frightened, he saw that the pool of water had been calm for a while, and soon condensed into ice, and the water surface was motionless, and it was completely frozen.

Yun Fei couldn't help but be dumbfounded, and he was amazed.

Suddenly I felt a warmth in my hand, and then I realized that when I was dodging in a hurry, I actually brought the jade stone with me. This time he was shocked.

You must know that the founder of this courtyard has worked hard to build this mechanism, and this small piece of Wen Yu is the key to it, it can be melted and opened every ten years, and now after Yun Fei takes Wen Yu away, this mechanism will not directly lose its role.

At this time, Yun Fei couldn't help but feel annoyed, but it was already unimaginable. The current situation can only be like this, and he has nothing to do.

Yun Fei left the pool at the moment, took the stone gate of the other courtyard as a starting point again, and after thinking about it carefully, he simulated a route and began to run over.

It turned out that before entering, the old man of Tianji had already drawn up a few routes for Yun Fei, but he hadn't fully figured out the mystery of this formation before, so there were some omissions.

Yun Fei scurried along the passage again, turned left and right, and after about half an hour, he came to the end. There was a stone wall in front of it, blocking the way.

Yunfei could only stop, turn his head in frustration, and go back the same way, because the end of this road was exactly what the old man Tianji saw when he was a child. When he returned to the stone gate, he immediately chose the second route and ran over again.

The old man of Tianji had planned nine routes for him, and if there were no obstacles, it would take five or six hours just to complete these nine routes. So, he now felt that it was all a matter of luck, and it would be much better if he could find the secret room in the first three routes.

Yunfei set off again, speeding through the circuitous passage, very quickly. But he always carefully calculated the distance and direction, and did not dare to be careless at all.

Less than half an hour passed, and this time it came to an end, and there was another stone wall in front of me, blocking the way. Yun Fei was silent for a moment, took a deep breath, and couldn't help but feel ecstatic in his heart, it turned out that he had already determined the location of the secret room.

It turns out that the end of this second route should have been a spacious stone chamber. Now it is not a stone room, but a stone wall, so it should be assumed that there must be a room in front of it, and in such a place, it is a place dedicated to the founder.

Yun Fei stood there fixedly, his body not moving, but his mind was running rapidly, repeatedly calculating the situation around him on the road he had walked, so that he could compare himself with his original position.

On the map, the size of the stone chamber was marked, it should be about seven or eight zhang, Yun Fei estimated the distance from Shimen Road, and calculated that the depth of the stone wall in front of him should be the same, and it can be determined at the moment. Now what I want to find is the door of the stone room, or this stone wall is just a wall, so I have to think about how to break through.

Previously, Yun Fei spent more than ten days noting down the formations in this courtyard, and memorized every road, way and length.

For the sake of prudence, he carefully calculated how long he had walked, and every detail could not be missed. Once he was sure that there was nothing wrong with him, he began to prepare for his hands.

So, he carefully examined the gaps between the stones, and the tentacles were so smooth that he could barely feel the existence of the gaps, which could not help but surprise him. But he was not discouraged, but went down to the top, slowly groping and checking. When I found it only two feet from the top of the wall, I found a gap that was less than the thickness of a finger.

But the gap wasn't very long, and it didn't go all the way into the stone wall. But this was enough, Yun Fei was suddenly ecstatic, opened his baggage, took out some tools from it, and began to act.

These tools are small and exquisite, which were specially designed by the old man of Tianji for Yunfei, and are used to knock on the wall and cut the cracks, but if it is not a person with strong martial arts, he must not be able to do it with force, and can only be used as a toy.

Yun Fei concentrated on it for a long time, expanding the gap he found to about half a foot deep, but he wanted to know how deep it was, but he was also a little uncertain.

For Yunfei, he can only bury his head in hard work now, trying not to let himself be disturbed by those frustrating thoughts. After doing it for a long time, suddenly the front was light, and I knew that the gap in the wall had been cut through by myself, and I estimated that this stone wall was only about a foot thick.

He was immediately in high spirits and mustered up enthusiasm to speed up. It wasn't until his hand could easily pass through the wall that he was ready to pry the stone with his tools, and sure enough, it wasn't very difficult, and he was able to pry off a piece of the stone in one fell swoop.

Looking through the exposed hole, I saw a portal in front of me, only about two or three feet away, but because it was too dark, I could only see one portal, and there was a door closed, but the rest of the situation was not clear at all.

Yun Fei vigorously moved the stone in the gap, and sure enough, his strength was not in vain, but quickly expanded a gap more than a foot wide and long with a sneer. Now he is not ready to dwell on this wall anymore, because time is the most important thing for him.

He estimated that the gap was almost over, so he immediately squeezed it sideways, stretched out his hand and touched it, and couldn't help but feel a chill in his heart, it turned out that the door was not ordinary, from the cold feel, it should be made of bronze.

Yun Fei only felt his heart beat wildly, and when he pushed hard, his heart immediately became like ashes, because this bronze door was not moving at all, and it was clear that there was some mechanism, and the portal had been sealed.

He suddenly became a little anxious, and groped the bronze door up and down, but found that there was no possibility of opening it at all, this time even if Yun Fei's psychology was strong, he couldn't help but sigh, and leaned on the door in frustration.

You must know that he has taken such a big risk, borne the infinite expectations of the three people outside, and abolished such a big manager, but he was blocked by a bronze door, and faced the fate of failure, how can he not be heartbroken or sad in his heart.

After a long time, I don't know how long it took, Yun Fei only felt that his head was empty, maybe it was an emergency reaction, so he turned it suddenly, and then he cheered up, took out a fire fold, and lit the fire with a 'pop'.
