At nine o'clock in the evening, Zhang Peng and others were ready to go, hiding in the alley opposite the giant coffin, and observing with binoculars.

A middle-aged nun with a sword on her back was sitting upright on the Taishi chair next to the coffin, closing her eyes and recuperating. Several garrisons armed with submachine guns stood near her, staring at the inside of the coffin, looking vigilant. Seeing that he couldn't get closer, Zhang Peng dialed Dai Le's phone.

"Director Dai, thank you for helping to support Master Miaoyue." Zhang Peng said.

"You ......," Director Dai was taken aback, "you want to go in?" ”

"The specific situation, too late to explain. What has been discovered and will not be forgotten by you. Zhang Peng said.

"Don't mention anything that you can't forget, they're all friends who have passed away. I'll do it right away. After speaking, Director Dai hung up the phone.

It didn't take long for Zhang Peng and the others to see Director Dai walking over slowly with his hands behind his back, like a walk, and then talked to Miaoyue Shitai. After a while, Director Dai seemed to have made some new discoveries, and then the two left together.

Looking at the back of Miaoyue Master who was too far away, the four mermaids rushed out and walked towards the coffin.

"Good evening, Comrade Advisor." When the garrison members standing guard saw the four people, they were stunned at first, and when they saw Zhang Peng's face clearly, they immediately saluted and greeted them.

"Good evening." Zhang Peng said in return, and then took Zhou Fuyuan and the other three people and walked directly into the coffin.

The guard opened his mouth, but didn't ask. After all, here, the highest status is the Heavenly Palace Advisor. Although he was a little strange, he didn't want to ask much.

Inside the coffin, four beams of light swayed back and forth, and the sound of splashing water kept sounding under his feet.

The four of them walked forward without saying a word, the ground dripping with water and the walls wet. A thin mist of water scattered in the beams of the flashlight. It was a very long passage, about the width of seven or eight people in parallel. The floor and walls are made of granite, and the surface looks slippery, as if covered with moss.

After walking for about three minutes, a huge bronze door appeared in front of me, four or five meters high, and it was filled with large willow nails.

Inside the bronze gate, there is a large square stone house. It was empty, and there were rows of long stone benches on either side, which was clear at a glance.

"This could be the antechamber of the cell, for people to wait for, or to organize things." Zhou Fuyuan said.

"Why was it built in such a place?" Zhang Peng said strangely. In fact, he wanted to ask this question a long time ago, even if he didn't understand it very well, he also knew the preciousness and rarity of space magic weapons. Otherwise, why haven't you seen it for so many years? It's a bit of a waste to use it as a prison cell.

"This is used to imprison cultivators, if it were an ordinary cell, I was afraid that I wouldn't be able to trap them, and I would have been freed out a long time ago." Zhou Fuyuan guessed.

After the vestibule, there is another passage, the top of which is arched, about three or four meters high. However, it is much narrower, and can only be used by three people in parallel. On both sides of the wall, there are many small doors more than a meter high, all of which are open. Looking inside, there are stone tables and benches, as well as stone beds.

"These should be the jailer's rest room." Zhou Fuyuan speculated.

"Hmm." Zhang Peng agreed.

"Do you feel like it's cold here?" The old yellow skin, who walked at the end, asked. Huang Mao is in the front, Zhou Fuyuan is in the back, and then Zhang Peng and Lao Huangpi.

"There was water everywhere, and of course it was cold." Huang Mao said disappreciatively.

"By the way, the airflow, where did the airflow come from?" Zhang Peng suddenly asked. If this is a mustard seed space and living creatures are imprisoned, how do you communicate with the outside world?

Zhou Fuyuan pulled down the yellow hair in front of him, motioned for the other party to stop, and then explained to Zhang Peng.

The mustard space is also known as the "half-plane" in science. Due to its incompleteness, the half-plane must be attached to the main plane. Microscopically, it can be seen as a spongy, perfectly transparent fluid, somewhere between matter and illusory, very similar to the properties of air.

Its materiality makes it objectively existent, while its illusory nature allows it to be penetrated by conventional matter. It exists, but it cannot be seen with the naked eye. Every point and every face of it is attached to the main plane.

Therefore, there is no problem of ventilation in the half-plane. Because it's transparent in itself. Its edges are seamlessly connected to the main plane, allowing air to enter and exit directly.

"Then why doesn't the water leak out?" Zhang Peng asked again.

"Maybe it's ......," Zhou Fuyuan said uncertainly, "the volume of water molecules is relatively large." ”

"I don't understand what you're talking about." Huang Mao looked stunned, and then urged, "Let's hurry up, otherwise the people outside will know about it and come in and arrest us." ”

"Let's go." Zhang Peng greeted.

The four of them continued to drip through the water and walked towards the depths of the passage. Zhang Peng and Zhou Fuyuan both consciously turned off their flashlights. It's humid here, and the battery drops quickly, so save as much as you can.

The last time they were trapped in the basement, they almost ran out of power and fell into a dark crisis. This time, Zhou Fuyuan also specially instructed Huang Mao to buy two glow sticks for each person. Unlike the burning rod, the former is a continuous low-light illumination, while the latter is a high-brightness illumination for a short period of time.

In a real adventure, glow sticks are more reliable than flashlights. On the one hand, the light stick is relatively light, on the other hand, the light stick is a divergent lighting, which is conducive to seeing the surrounding environment clearly, and is more resistant and waterproof than a flashlight.

All four of them carried military backpacks and prepared a lot of survival supplies. Zhou Fuyuan and Zhang Peng are both cautious people, even if they are dungeon adventures, they have prepared a lot of survival materials for the wild. In case you get stuck, there is still water to drink and compressed biscuits to eat.

Huang Mao held a crowbar in one hand and a flashlight in the other, carrying a military bag and a mountain knife behind his back, and a dagger pinned to his waist. Lao Huangpi also carried a mountain opening knife on his back, but Zhang Peng and Zhou Fuyuan only took daggers, on the one hand, it was heavy, and on the other hand, it was useless to take it.

Zhou Fuyuan is chubby, he is not young, he is really going to encounter danger, and he is no different from sending meat with a mountain knife. And Zhang Peng has a gun, so there is no need to bring a mountain knife. However, even if he can dance twice, he is not much different from Zhou Fuyuan.

Although Lao Huangpi is not young, it is estimated that it is a problem of experience, sleeping outside all day long, running around, so his physical strength is better than Zhang Peng. Among the four, it is second only to Huang Mao.

Huang Mao's stature is not tall, only more than one meter six, and his physique is not strong, but his muscles are relatively strong, and he belongs to the lean type. I saw him walking in the front, his little eyes sweeping around, and he seemed more sensitive. But in fact, Huang Mao's reaction was not fast, otherwise he would not have been stung by a mountain bee to cry his father and mother last time he was in Scalper Mountain.

At the end of the passage is a narrow iron fence gate that can only be passed through by one person. The thumb-thick iron bar was rusty and badly corroded. There was a large iron lock hanging from the latch, which was also rusty, and Huang Mao kicked it open.

I saw him get into it sideways, and the flashlight shone around, and I couldn't help but let out an exclamation.

"Wow......"

Not feeling the danger, Zhang Peng followed Zhou Fuyuan in. Huang Mao pulled out a burning stick from his backpack, twisted the lid open, then pulled out the dagger and wiped it hard at the bottom. The incendiary rod burned, spewing out a large amount of sparks and smoke. Huang Mao threw it with all his might, and the incendiary rod arced in the air and fell more than ten meters away.

The intense light of the fire suddenly illuminated the surroundings, which was a huge underground space with thick stone pillars everywhere. The top is very high, there are more than ten meters, all are stone walls, wet, dripping water droplets from time to time.

Due to the presence of stone pillars, although the place is large, it appears less empty and even a little cramped. Looking at it, the three people behind them all took a cool breath.

As the light of the fire lit up, figures appeared on the stone pillars. They all hung their heads down, their bodies were wrapped in chains, and they were tied to stone pillars.

Some of the corpses were highly decomposed, and only Bai Sensen's bones remained. Looking up, the stone pillars are from top to bottom, wrapped in dense corpses, and people's scalps are numb. On closer inspection, the corpses all have a common feature, which is that the lute bone is pierced by iron chains.

It's not hard to imagine how cruel the owner here is. Tie the living to a pillar until they die. Even if it is very old, you can see the traces of struggle from the corpse.

Huang Mao was the most courageous, and he didn't hesitate for long, so he walked to the nearest stone pillar and stabbed the corpse with the crowbar in his hand while the burning rod was still burning and the fire was bright.

The corpse hung its head motionless, and Yellow Fur lifted the crowbar again and struck the skull next to it.

"Aggressive ......"

"Hahaha, look, it's about the same as a wooden fish." Huang Mao said with a smile, and went to knock on the skeleton next to him again.

"Aggressive ......", "Aggressive......" "Aggressive......"

He knocked several skeletons on the back of the head, but there was no response. Preliminary judgment, there are no living corpses.

"Dangdang!" Huang Mao raised the crowbar, sounded himself in his mouth, and made a gesture of victory.

But at this moment, the skull behind him moved slightly.

"You, you're behind!" Zhang Peng reacted the fastest and shouted at him.

Huang Mao's face changed, and he hurriedly looked back, only to see a skeleton slowly raise its head, and a faint green light appeared in the hollow eye sockets, like the legendary fire, cold and deep, making people shudder.

I saw Huang Maoyan quickly swing the crowbar and smash it on the skull, and with a "pop", the skull fell and fell to the ground and rolled with a clatter, bringing up pieces of splash.

After a moment of silence, Huang Mao cautiously moved over. But as soon as he got closer, the skull moved.

"Giggle...... Giggle...... Giggle......"

Its jawbones bit at a high frequency, and the few remaining teeth slammed into each other with a oozing sound.

"it!" With a shake of his hand, Huang Mao swung a crowbar and knocked the skull several meters away.

After a while, the turquoise glow in the skull's eye sockets gradually dimmed. At this time, the incendiary rod was also burned out, and the surroundings were completely black.

The flashlight's beam lit up, but only a small area. But no one offered to use the incendiary stick again, it was too precious to burn for less than fifteen minutes.

"How?" Huang Mao returned to the three of them and asked Zhou Fuyuan and Zhang Peng. Zhou Fuyuan looked at the latter with inquiry in his eyes.

"Hmm......" Zhang Peng pondered for a while and said, "Let's look around first and see if there are any clues." He didn't know what was inside, so he could only look at it as he walked and act when he saw the opportunity.
