Outside the mountain, Yu Hui stood with a group of teachers and disciples who hadn't gone in, surrounded by some villagers watching.

"It still doesn't work," Elder Yu Hui said after several attempts, but he couldn't break the barrier.

A smiling face appeared on the barrier, "How could someone as low as half-step Profound Origin Realm possibly break through the barrier of the Profound Origin Realm?"

Zhou Yuhe was a little anxious and asked, "Mr. Yu, what should we do next?"

Elder Yu thought for a moment, then said solemnly, "Yuhe, go back to the sect quickly. Find other elders to come over; they must be at least at the Xuan Yuan cultivation level. Do you understand?"

Zhou Yuhe nodded, then flew towards the Xuanyu Sect.

Hopefully it's not too late.

With her Heavenly Origin Realm cultivation, it would take her about four hours to return, while it would take the Profound Origin Realm elder about an hour to arrive here.

Therefore, it should take less than six hours to bring reinforcements.

......

Inside the dark cave, the group gathered firelight with their spiritual energy. They walked on the wet ground, with water droplets falling from time to time around them.

"Whoosh, whoosh, whoosh..." Suddenly, the darkness ahead was gone.

The ground was no longer damp; it had become a stone floor. Two rows of torches on the walls slowly lit up as people arrived, emitting a rhythmic sound.

Not far away was a stone gate, with three large characters carved above it: "Demon Sealing Cave".

"This is actually the Demon Sealing Cave," Lu Cheng said, clearly surprised.

Peng Fei looked at Lu Cheng, "Brother Lu, do you know where this place is?"

The latter nodded and slowly said, "Legend has it that a long, long time ago, the planet Xuanxing did not have separate eastern and western regions..."

Lu Cheng said a lot, but in summary, it is that humans, demons, and monsters used to coexist on Xuanxing. Later, as the strength of the human race grew, the demon and monster races feared the rise of the human race, so they launched a great chaos and massacred the human race.

The human race united to drive the demon and monster races to the Western Regions. Now, only a small number of demon cultivators and monsters remain in the Eastern Regions.

However, due to the special secret techniques cultivated by many demons and monsters, they cannot be completely killed, or killing them would come at a great cost.

Therefore, some Demon-Sealing Caves and Monster-Sealing Caves were built to seal them. The sealed demons and monsters all had at least the cultivation level of the Profound Origin Realm.

“But usually, the energy in a sealed cave is sealed off, so we don’t know how the person outside found it,” Lu Cheng continued.

No wonder that person couldn't get in; it turns out to be the Demon-Sealing Cave, Lu Cheng thought.

Because the Demon Sealing Cave contains many traces of human Taoist magic, demons cannot enter.

After listening, Sui Xin asked, "Then, Brother Lu, do you know how to open the door?"

He had to hurry; Yun'er was still waiting for him.

Lu Cheng knocked on the door and said, "Generally speaking, the Demon Sealing Cave cannot be opened without sufficient strength, but after so many years, the door is basically corroded beyond recognition."

No sooner had he finished speaking than a large piece fell off the spot where he had been hit.

Without saying a word, Lu Cheng smashed the door with a punch. "Let's go!"

Although he didn't care about Wang Kun's life or death, other people's lives were also lives, and as a disciple of Xuan Yu, he couldn't just sit idly by.

Everyone nodded, said nothing more, and entered the Demon Sealing Cave together.

As the group entered, they were greeted by a vast cavern radiating golden patterns. The surrounding area was a labyrinthine network, resembling a giant anthill, and the floor was littered with black bones.

"The golden patterns should be the sealing array, which can directly crush any demons that enter. These black bones on the ground are from some low-level demons who were killed," Lu Cheng explained.

"Then what are these passageways for?" Wu Qianyu asked.

"There are always those with ulterior motives who want to open the cave and rescue the demons. These passages are meant to mislead them, so choosing the wrong one could lead to treacherous situations."

"So what do we do? Which road should we take?"

"Won't we have to release the Demon King to get that sword?"

......

Several more people asked the question aloud.

Lu Cheng remained silent. There were some things he didn't understand very well, and he was already quite satisfied with what he knew.

"How about we split up into pairs and explore separately? That way we can look out for each other, increase efficiency, and return immediately if we encounter danger," Sui Xin suggested.

Peng Fei nodded: "That's fine, but please don't force yourself."

Safety is always the most important thing, for the average person.

"I want to be on the same team as Lu Cheng."

"I want to be paired with Lu Cheng too."

Before the game even started, everyone started arguing about the team assignments, all wanting to be on the same team as the formidable Lu Cheng.

Sui Xin quickly interjected, "How about this? We'll draw lots to decide. People who draw the same number will be on the same team, okay?"

“I agree,” Lu Cheng said first.

Since Sui Xin's cultivation level was too low, he could only take the initiative to help Sui Xin find a way to settle scores.

Seeing this, the others had no choice but to agree.

Take out a pen and paper at will, and prepare ten crumpled pieces of paper, with two sets of numbers from one to five.

The results of the draw came out quickly.

Chen Cheng and another seventh-tier team, Peng Fei and an eighth-tier team, Sui Xin and Wu Qianyu team...

"Alright, everyone, let's go!"

Everyone chose a passage and walked in.

They chose the leftmost path.

As soon as I stepped onto that road, I felt the scenery around me change, and a wave of heat hit me.

The first thing you see is a very narrow path, with scalding lava below.

You can feel the extraordinary heat just by standing on it.

"Let's go quickly," Sui Xin said, glancing behind her at Wu Qianyu.

The latter remained silent, his face cold.
