The gate of the ancient city was pushed open by Li Mang, and a dust-sealing breath suddenly came to his face, making him feel eternal and feel the passage of time.

But in the obscurity, Li Mang also smelled a breath of death.

Mo Ao and the others, who were originally eager to enter, couldn't help but stop at this moment, their eyes were gloomy and uncertain, and they were afraid that there was no beauty in it as they imagined.

"There seem to be a few words on the door, right?" Li Mang asked suddenly.

“…… It seems to be, but I didn't see it clearly just now. The snow god replied, and the rest shook their heads one after another.

“…… Mo Ao, aren't you going in? Now you can go in and have a look. Li Mang looked at Mo Ao, and said in a good voice.

“…… I'll take a look at what is written on it. Mo Ao is not stupid, this evil aura even he, a demon cultivator, feels uncomfortable, how dare he step in recklessly, so he found an excuse and hurriedly retreated.

Li Mang glanced at each other with a few of them, and also tacitly exited the door.

The city wall is very high, with a height of hundreds of meters, even if it has retreated more than ten meters, it is still not clear to see the situation on the city wall.

At a height of thirty meters, there began to be some black fog, so that a door plaque in the center had not been noticed by them before, but this time they looked carefully and finally saw what the words were.

"Pig Prison"

These four ancient words made the hearts of twelve people sink at the same time.

The meaning of the pig could not be clearer, it is an ancient holy beast; Zhen, on the other hand, means to suppress; Prison is prison.

Taken together, this is a prison suppressed by pigs.

The pig is full of righteousness. It is a divine beast used by the cultivation world in ancient times to suppress demons and monsters, and only demons and monsters can be suppressed by hedgehogs.

And since this is a prison suppressed by the pigs, then...... I'm afraid that the people inside are demons and monsters.

No wonder. This city wall is built 100 meters high, this is a convulsive thing, it was originally specially built to suppress demons, not an ordinary city.

"Seemingly...... Are we in trouble? Li Mang looked at them and asked.

"Seems to be." The snow god replied coldly.

"We're not going to release some Ancient Devils, are we?" The big sword boy swallowed his saliva and asked, if he didn't care about his face, he would definitely turn around and leave. The master once told him that he would run away when he was in danger.

"It's hard to say. This Pig Prison does not exude a demonic aura at the moment, but it has a more terrifying death aura. Shu Dai Muran said, naturally stupid.

"Or ...... Shall we leave? Bajie whispered a solicitation. The Xiuzhen kid beside him was also busy nodding his head, while the Thunder Emperor had a gloomy face and didn't say a word.

The second young master of the Tianbao Chamber of Commerce was also silent, and did not object to Bajie's proposal. They could all feel the evil of this pig in prison. Don't want to put yourself at risk.

"Now that it's here. Why leave? A group of imps who are greedy for life and afraid of death! Mo Ao made sarcastic remarks despite an angry gaze.

"The door seal has been opened by us, no matter what the situation inside is, we must go in to find out, and if there is really any change, we can also report it to the seniors outside in time." The snow god also said at this time.

"The god of snow is right, we must go in and find out." Li Mang also agreed.

Although there was resistance, now that it had been discussed, a group of people also walked cautiously towards the city gate again. This time it was still Li Mang who came to the front, but it was not the same as before. This time, he was a little worried in his heart.

The moment he stepped through the city gate, Li Mang felt as if he had stepped into a lifeless hell. When I glanced ahead, I saw a dilapidated compound, with rubble everywhere, and stone pits left over from the fighting.

There wasn't a single plant in the courtyard, and it looked like they were all dead. On both sides are stone caves made of stones, and the entrance of the cave is black, giving people a secluded feeling.

There are piles of regular stone fragments scattered in front of the stone cave door, which seems to have been originally a stone gate, but it has been destroyed by something.

"Would you like to pick one and take a look?" Li Mang proposed to ask, and seeing that they did not object, he chose a stone cave at the door and walked to it.

Standing at the door and smelling it, although there was a dead breath inside, there was air circulation, and it should be non-toxic, Li Mang continued to walk in, and when he saw that the environment was dark, he planned to take out a flashlight.

"Click!"

A crisp sound startled him, and at the same time, the stone cave also appeared, and the oil lamps on the stone walls on both sides lit up on their own.

"Huh, voice-activated lights?" The big sword boy looked surprised.

"......" Li Mang and the others were surprised, it was obviously an oil lamp, right? But because they can't explain it themselves, they can't refute it.

"It's a beacon." Shu Dai has read a lot of books, and his knowledge is beyond ordinary people, so he can see at a glance what the specific name is.

"Don't bully me for reading less, I've heard of the ever-bright lamp, but I haven't heard of something that can be lit by yourself." The big sword boy was a little unconvinced.

"This is because there is a formation in the stone cave, and when someone comes in, the formation will light the everlasting lamp, and when it comes out, it will slowly extinguish." Shudai's explanation of the slow method.

“…… It turns out that this is the case, the wisdom of the ancients is really bullish. "The big sword boy can't accept it this time.

Li Mang and the others also sighed when they heard this explanation, but this was just an episode, they were more concerned about the situation in the cave and what was inside.

The space of the stone cave is relatively rough, without any decoration, there is a cold iron pillar in the front, the lower head is inserted into the ground, and the upper head is also embedded in the stone wall, and I don't know how long the two ends of the road are. The iron pillar was wrapped with a wrist-thick iron chain, and the cold air on it made Li Mang and the others shiver.

As for the source of the dead air, they could see it at a glance, it was a pile of fragmented bones under the iron chain, but they could vaguely make out that this was not a human bone, it was very thick and black.

Although he was dead, there was still a lot of life-like aura in his bones, evil and fierce, even Mo Ao didn't dare to look away for too long, otherwise it would be very uncomfortable.

"These bones are all treasures, if you take some of them and incorporate them into a weapon, you can definitely forge them into a killing weapon." It was still the big sword boy who was the first to make a sound.

Everyone was speechless, but then their eyes lit up, obviously moved by him.

"Take two pieces each!" Li Mang said.

Everyone was not polite, and the twelve people in the field had storage equipment, which was easy to carry. The big sword boy didn't have it, but he still had a few storage bags hanging on his body, so he was naturally worry-free.

Li Mang endured the discomfort caused by the death qi on himself, squatted down to examine a broken bone, and muttered softly: "Judging from the marks on it, this demon beast was eaten by something." ”

Hearing this, the air in the cave was suffocated, and everyone looked down carefully, and sure enough, there was a tooth mark on the bone.

The tooth mark is so large that it can be inferred that it is not human, and it is very sharp and strong. Because the bones that have been sealed for many years are still hard, Li Mang cut a few times with his hedgehog sword, and if he doesn't inject internal force, he can't even leave a trace on it.

But there was a tooth mark on this bone, and you can imagine how powerful the owner of this tooth mark is. Suddenly, a shadow covered their heads, and they unconsciously asked in their hearts: Is this monster still alive?
