Chapter 868 Abnormal Sound

"Well, he is definitely not taking poison." Zhang Yu said, scanning the large room, and his eyes were quickly attracted by the junk on the other side.

Pan Yun also looked over. On the surface, it looked like scrap metal, but upon closer inspection, it was not difficult to see that it should be some machinery and equipment. The most obvious thing is that there are some pipes on the wall, which were most likely originally connected to the equipment.

After examining it for a moment, Pan Yun's eyes lit up and he said, "These things seem to contain poison gas?"

"That's right!" Zhang Yu suddenly understood and said: "The pipes on the wall must be connected to the gas chamber and virus chamber in front of this person."

At this point, Zhang Yu glanced at the dead body and said accurately: "He must have used thunder to break these devices. The poisonous gas leaked and poisoned everyone here. Even he himself was not spared!"

"Yes! That must be the case! Otherwise, those Japs couldn't have died for no reason!" Pan Yun nodded heavily, agreeing with Zhang Yu's statement.

At this moment, a picture appeared in front of Zhang Yu's eyes.

It is this Taoist priest who came here disguised as a Japanese. His goal should be very simple, to destroy this hell. It should have gone smoothly before, but it was still exposed here, attracting a large number of Japs, and even an Onmyoji master. This was bound to be a thrilling and bloody battle, but in the end the Taoist priests relied on their profound Taoist skills to die together with the Japanese.

Perhaps, the Taoist priest still hoped that he could escape, so he did not dare to directly break the poison gas device. However, because there were too many devils, it was difficult to resist them, so he had no choice but to do so.

"Zhang Yu, we have figured out what is going on, and we have captured Hatano Baiyi. What should we do next, should we go back." Pan Yun saw that Zhang Yu remained silent for a long time, so he simply reminded him.

In Pan Yun's eyes, finding these is enough. With the information in hand and Hatano Baiyi as a living person, once the evidence is presented to the patrol main office, everything will be revealed.

Fu Senbo contracted the mine to the Japanese and asked the Japanese to search for secrets. Regardless of whether he knew the inside story or not, it was already considered treason. As for whether the virus in Guangming Town was caused by the islanders and Fu Senbo, even if there is no conclusive evidence, Yin Ming can still make a rough guess.

The purpose of Zhang Yu's visit this time was mainly to search for the "Tian Yi Mi Tu" and to check on the little devil. I didn't find "Tian Yi Mi Tu", but I ran here by mistake and discovered this secret.

In fact, he wanted to continue searching, but he also knew that there must be other dangers in the mine. It's okay for me to be alone, but with Pan Yun here, once I encounter many opponents, I'm afraid I may not be able to take care of Pan Yun.

Now Pan Yun offered to leave, which suited Zhang Yu's wishes. After leaving, it would be a good idea to find a chance to come over by yourself.

So, Zhang Yu nodded and said, "That's fine, let's first..."

"boom!"

Before Zhang Yu could finish his words, a loud noise suddenly sounded. Not only was the sound loud, it was so powerful that people's feet trembled.

Hearing this sound, Zhang Yu and Pan Yun couldn't help being startled and looked at each other.

"What's going on?" Pan Yun said worriedly.

"This sound seems to be coming from the direction we came from. Let's go over and have a look." Zhang Yu suggested.

"Okay." Pan Yun nodded.

Zhang Yu stood up, walked to Hatano Baiyi, and lifted him up again.

Pan Yun followed him, and the two of them left the room together.

They returned the same way and came to the T-junction just now. Zhang Yu was just about to walk back and forth when he suddenly heard a "swishing" sound coming from the opposite intersection.

The sound is not loud, and ordinary people should not be able to hear it.

"Pan Yun, what did you hear?" Zhang Yu asked in a low voice.

"No." Sure enough, Pan Yun shook his head.

"Whoosh, whoosh, whoosh." "Whoosh, whoosh, whoosh."

The sound continued, and I didn’t know what it was.

Zhang Yu glanced at Hatano Baiyi and said, "Did you just come from there?"

"Yes." Hatano Baiyi said honestly.

"Did you find anything over there?" Zhang Yu asked.

"There are several stone chambers over there, but they all have doors. We didn't open them out of caution, we just searched all the way here," Hatano Baiyi said hesitantly.

"There are still a few stone chambers." Zhang Yu muttered, "Did you really not open them?"

"Really!" Hatano Baiyi said immediately.

"Whoa, whoa, whoa." "Whoosh, whoa, whoa."

This voice still didn't stop, making Zhang Yu more and more curious.

"What's wrong?" Pan Yun asked softly.

"I heard a sound over there, but I don't know what it was." Zhang Yu said.

"There is a sound." Pan Yun listened carefully, but heard nothing.

She shook her head and said, "I didn't hear it, and I don't know what's there? Do you want to go there?"

Zhang Yu thought about it for a while and decided that safety should come first. It didn't matter if he was alone. He took Pan Yun with him. If he had gained enough, it was better not to take any more risks.

"If we can't pass, let's go back first." Zhang Yu said.

At that moment, the two of them set foot on the way they came. They walked through the corridor of Thousand Body Ksitigarbha, then passed the corridor of the prison cell, and finally arrived at the large stone room with a table and bed where they first entered.

All the way down, everything looked normal, nothing wrong with it, just like when they came here.

"There seems to be no problem. But what happened to the loud noise just now?" Pan Yun said in confusion.

"I don't know either. However, since we have decided to go back, why not go back now." Zhang Yu said.

"That's fine." Pan Yun nodded.

They walked down the steps. Knowing that there were bats on the top, Zhang Yu did not dare to be careless. He raised his hand and threw a fire gathering talisman up first.

"puff!"

A ball of fire shot up, followed closely by sparks.

Zhang Yu kept looking up, and he could see clearly that the fireball hit a stone wall solidly.

"Huh?" Zhang Yu was shocked when he saw this scene.

When it came, it was a mechanism opened from the outside, and the stone door was raised. How come when I look back, the stone door closes by itself?

"What's going on? Why did the stone door close by itself? It couldn't have been closed by someone..." Pan Yun became nervous again unconsciously.

"Don't worry, there must be a mechanism here. Let's go up and have a look." Zhang Yu said calmly.

With the power of his ears, he was able to determine that there should be no one around. Of course, he was also very surprised. Why was the door suddenly closed when he came?

The messy firelight remained on the steps. Zhang Yu deliberately blocked Hatano Baiyi in front of him and walked up the steps.

Pan Yun followed behind with a flashlight and climbed all the way to the top.

The stone gate is tightly sealed and blocks the way.

"You help me look after it, and I'll look for it." Zhang Yu said, throwing down Hatano's white clothes, and started looking for the mechanism under the light of the flashlight.
