The barefoot old ghost was angry when he saw Du Yong's timid appearance.

Yang Jin picked up a stone, smashed it hard, and hit it on the ground of the passage.

After waiting for a long time, the stone door slowly closed.

Du Yong shouted: "Look, after stepping on the ground, it will automatically close after a while."

"Awesome!"

The barefoot old ghost was amazed, turned his head to look at Dahei, and ordered: "Open the door."

Dahei curled his lips, walked over helplessly, reached out to touch the switch, and the stone door opened again.

The barefoot old ghost coughed twice and looked at everyone: "Why don't you go in together?"

Yang Jin and others immediately stood beside Du Yong and confronted the barefoot old ghost.

The barefoot old ghost looked dark: "What do you want to do?"

Du Yong smiled and said, "Don't be so serious. I promised before, you always take the lead. Now you need to find the switch inside. You are more than enough. You don't need to pull me up. Just shout if you have anything, and we will open the door immediately."

The barefoot old ghost took a deep breath and chuckled, "You have to be so careful?"

Du Yong sighed: "Senior Barefoot, can you change my position? I'm just a small sealing realm. Without knowing the switch inside, how dare you enter."

He paused and said seriously: "I have a compromise."

The barefoot old ghost raised his hand and signaled Du Yong to continue.

Du Yong took down all the vines and branches on his body: "We will give you the equipment. In that case, even if we want to run away, we will not be able to get out."

The barefoot old ghost thought it was feasible and said lightly: "This method is OK."

Yang Jin and others quickly took off the equipment, stacked it together, and handed it all over to the barefoot old ghost.

The barefoot old ghost looked at Du Yong and sneered: "You boy, such a thief, how can this be used to do a big thing?"

Du Yong disliked it and smiled and said, "What you have taught is the lesson."

The barefoot old ghost was speechless and had to pick up his equipment and step into the stone gate.

It was still the same, and after a while, the stone door automatically closed.

The barefoot old ghost disappeared before his eyes, and Du Yong said, "This mechanism is very mysterious. With such a heavy stone door, where does the power to push the door come from?"

Pinyuren guessed: "In my opinion, we should have used the power of groundwater."

Yang Jin nodded in agreement: "There are indeed many institutions that use hydraulic power."

He Laosan laughed and said, "If it happens to be a severe drought, wouldn't this thing be invalid?"

Yang Jin shook his head: "I have never heard of a severe drought in Youmangshan area."

Dahei didn't care about the mechanism and whispered: "This big-footed monster also said that he was a thief, and he himself was also very thief."

Du Yong immediately agreed: "That's right, I've agreed to take the lead, but in the end I'm timid. I pretended so imposing, but I took away our equipment without hesitation."

As soon as he finished speaking, the barefoot old ghost's voice came: "I can hear it."

Dahei and Du Yong immediately smiled awkwardly, and the former quickly said flatteringly: "Senior, have you found the switch?"

The barefoot old ghost replied: "I didn't see anything special."

Du Yong casually said, "Isn't there a lamppost? Twist and take a look."

The barefoot old ghost followed the flow of good deeds and began to twist the lamp post. Suddenly, a bang sound came from inside.

Du Yong quickly asked, "Senior, what's the matter?"

The barefoot old ghost did not respond. After waiting for a while, the stone door slowly opened.

Everyone was overjoyed and hurried in.

The barefoot old ghost pointed to the second lamppost on the left: "It's it."

After the door was closed, Du Yong tried to twist the lamp post for experiments, and it went very smoothly.

Yang Jin divided the equipment into one point: "Put it back on."

Dahei was a little reluctant: "There should be no ice bats inside, right?"

Yang Jin smiled and said, "Then put it in your bag."

After understanding the mechanism, everyone had a clear mind and continued to move forward under the leadership of the barefoot old ghost.

The passage is very long, with a slope downward and the oil lamp is not broken.

Although it was a stone slab, you could still see the traces of the big black snake sliding by, and the fishy smell was also followed.

"stop!"

The barefoot old ghost suddenly raised his hand and said in a deep voice: "I heard the sound."

Du Yong raised his true energy and listened carefully for a while, but heard nothing. He had to ask, "What sound?"
