Skilled in managing a house

"Can you hear me now?" Zhang Yu asked with concern.

The young man saw Zhang Yu's mouth moving and said, "What did you say?"

This look is just like Zhang Yu before.

Zhang Yu knew that she would not be able to hear him, so he could only wait quietly. The young man also started to press his ears. After a while, she said: "I finally understand why the person who delivered the food is deaf and blind."

"Why?" Zhang Yu asked.

"With this formation, it is absolutely impossible for a normal person to walk through it. Unless the person is deaf himself, he cannot hear anything." The young man said through gritted teeth.

"That's right..." Zhang Yu took a breath and then said helplessly: "Then we can't make ourselves deaf just to go out..."

"This..." The young man looked frustrated. Just as Zhang Yu said, he couldn't make himself deaf.

She was leaning against the wall just now, but after she stood up straight, she stopped leaning against it. Because of her frustration at the moment, her back unconsciously leaned against the stone wall again.

There was a soft "bang" sound, and his back hit the stone wall.

She didn't think anything of it, but Zhang Yu, who was standing opposite her, immediately noticed something was wrong and said, "The wall behind you seems to be empty."

"Empty!" After hearing this, the young man immediately became energetic. She turned around quickly and patted the stone wall with her hands.

"Bang bang bang..." Shibi's voice was very thick, without any hollowness.

The young man said: "It doesn't look like it's empty?"

"There is a hidden mechanism here. Most people can't hear it, but I can!" Zhang Yu said with certainty.

"There is an agency... Then come and take a look..." The young man immediately stepped aside.

Zhang Yu walked to the stone wall, raised his hand and knocked a few more times.

The sound inside was very real, and it really didn't sound like it was empty. If it had been before, Zhang Yu wouldn't have been able to distinguish it. But since he learned the art of traps, he has been able to distinguish the presence of traps from subtle sounds.

He then tapped surrounding areas to determine if there were any differences in the sound. Soon, Zhang Yu was completely sure that there was indeed a problem here.

Zhang Yu played another Fire Gathering Talisman, which allowed him to clearly look at the stone wall. The stone wall is not particularly smooth, there are ridges and depressions on it. Zhang Yu's hands were tapping on the stone wall, or pressing the ridges and depressions on it, feeling the sound the stone wall made.

Soon, Zhang Yu discovered that when his fingers pressed hard on the raised or depressed areas, there would be a faint sound of pulleys in the stone wall. Although it was very slight, it couldn't be hidden from Zhang Yu's ears. Zhang Yu was able to determine that this should be a clever mechanism, similar to a modern combination lock. The raised and recessed areas on the top are actually passwords, which must be pressed in sequence to open.

Cracking a combination lock is a test of your ear. Generally speaking, a completely correct code sequence can make the machine spring inside make the same sound, thereby opening the lock. If different sounds appear, it means the order is wrong.

Zhang Yu tried again and again, and this time, three identical sounds finally appeared in succession. Zhang Yu is absolutely certain that he has successfully found three sequences this time. Maybe with one more, maybe with two more, he should be able to open this mechanism.

Recalling the sound he made when pressing it before, Zhang Yu slowly moved his fingers to a grooved ground.

He just pressed hard and heard a "click" sound, and the stone wall in front of him moved. It started to rise slowly.

"There really is a mechanism!" The young man was stunned when he saw the stone wall rising.

She really couldn't believe that there was actually a mechanism here. Zhang Yu had been studying it for so long and could actually open it.

As the stone gate rises, there is another stone gate after the stone gate. However, there is a copper ring above the front of the stone door. It seems that as long as the copper ring is pulled, the door can be opened.

Zhang Yu was not in a hurry. He looked at it first and then grabbed the copper ring. He pulled down gently, but he was also careful to avoid any traps. Not to mention, there was no mechanism. As he pulled, the stone door behind slowly rose.

When the stone door is raised, a cave is revealed behind it.

"There is a way..." The young man was overjoyed and couldn't help shouting.

There is no way to walk through the normal passage. This cave right now can basically be said to be the only chance for the two of them.

With a "pop" sound, Zhang Yu inserted a fire talisman for lighting.

The cave is not long, and the end is about ten meters ahead. Precisely because it is relatively short, Zhang Yu and Zhang Yu can see clearly that there is a turning passage to the right at the end.

"I'll go in and take a look first." Zhang Yu held the Seven-Star Sword and walked in slowly.

The young man followed behind, walking very slowly.

The two of them walked one behind the other until they reached the corner. As soon as Zhang Yu's foot touched the corner, he heard a soft "click" sound, and the ground seemed to sink a little. Zhang Yu quickly took two steps back, and then heard two "clang" sounds behind him.

The two of them looked back together and saw that the stone door that had risen before fell down at an extremely fast speed and hit the ground hard.

"Why...why is the door closed..." the young man said with a frown.

"It doesn't matter. This should be a self-control mechanism. The purpose is to prevent others from discovering the mechanism stone gate here after entering." Zhang Yu said.

"So that's it, what should we do now?" the young man said.

"There is no other way. We have only one way, which is to keep moving forward." Zhang Yu said.

"Yeah." The young man nodded.

Now that the two people have opened the mechanism and come here, they can't look back and can only continue to move forward.

Following the dark corridor, the two slowly walked forward. Zhang Yu threw out a fire talisman from time to time for lighting.

As I walked, there was a double intersection ahead.

One path leads to the left and one to the right.

Seeing that there were two options, Zhang Yu stopped and looked at the young man beside him, "I can't believe that this passage is not only quite long, but there are two roads. Which one do you think is better?"

"This..." The young man hesitated for a moment. God knows which path is more reliable. After thinking for a while, the young man pointed to the intersection on the right and said: "Otherwise, choose this one... If it doesn't work, let's choose another one..."

"Okay." Zhang Yu nodded.

How to choose between the two roads is actually the same for the two of them. They should take one first and then talk about it. If it doesn't work, then turn back and take the other.

The two of them immediately walked towards the intersection on the right and continued to move forward slowly along the corridor.

After walking for a while, we reached the end. There is a stone wall ahead and there is no road.

"This is the end." The young man said a little disappointed.

"Let me take a look." Zhang Yu said, walked to the stone wall, stretched out his hand and started tapping.

"Bang bang bang..." This sound is very similar to the sound of the previous mechanism. Although it is real, Zhang Yu is sure that this is definitely a trap door.

"This is also a mechanism." Zhang Yu said.
