The old man laughed, but did not say anything. He slowly picked up a chess piece that was in his hand and placed it on the board, then gently placed it on top. A crisp sound rang out, and an aura slowly spread out, causing the entire world to seem as if it had stopped moving, following that, all feeling disappeared as the old man stood up and looked at Lu Ming with a smile, "Don't be anxious."

As he spoke, the old man walked away. This was the forbidden zone of the academy, and other than the Principal and the elders, no one else could enter, while the old man brought Lu Ming in.

This was also the first time Lu Ming had been here. This was a cave, and the cave was sealed, making it look like ripples on the surface. The old man placed his hand on the seal, turned it gently, and the seal slowly disappeared.

As soon as he walked in, a burst of cold air blew over him. This place was completely different from what Lu Ming had imagined.

Surprisingly, it was filled with a sinister aura, as if it had fallen into hell. Everything around him was pitch black, and wave after wave of cold yin energy directly pierced into Lu Ming's soul. Lu Ming hurriedly used his spirit energy to protect himself, but to no avail.

When the old man saw this, he smiled slightly and patted Lu Ming's shoulders with his hand. A curtain of light appeared and enveloped the old man and Lu Ming.

"Elder, what kind of place is this?" Lu Ming looked around and could not help but ask in surprise.

"You'll know when the time comes."

As he spoke, the old man slowly floated away from the ground and walked deeper in. Lu Ming could clearly feel that the cold yin energy here was even richer.

"Elder, are you alright?" Lu Ming asked quickly.

The old man shook his head and didn't say anything. This wasn't the time to be distracted, and after flying for an unknown period of time, the Elder stopped. In front of him was a large sphere of light.

Floating in the air like that, Lu Ming had just tested it. No matter what light it was, even if it was a fireball, it would be engulfed by darkness. The darkness in this place didn't seem to be caused by the absence of light, but a substantial existence.

However, this ball of light was not ordinary. Like the sun, it illuminated the surrounding environment.

The old man let out a light breath and slowly flew over. There was a door at that location. The old man opened it and flew in.

The place was filled with birdsong and fragrant flowers. The trees were lush and verdant. There was a stream beneath his feet, but when he looked up, he could see the huge screen of light.

"This is a sealed world." The elderly laughed as he brought Lu Ming in one direction.

It was a small path, and after walking along it twice, he suddenly turned a corner, and Lu Ming suddenly saw what happened in front.

Just what sort of shocking scene was this?

Right in front of him was a huge array. On the ground, there were 12 people sitting around the array. They were all sitting cross-legged, and each of them was enveloped by a ring of light with their eyes closed.

The ground floor to the sky was like a pagoda, and each floor had 12 people sitting around it. Now, it looked densely packed, with over a thousand people in the sky.

Every level of the array was different, and the sizes were also different. Some were small, some were big, and some were bright. The symbols on them were also different.

"I'll explain the details to you later. Have you seen that there are only 11 people in the top layer?"

Lu Ming raised his head to look. As expected, there were only eleven people in the biggest formation at the very top.

"Hurry up and make up for the 12th person. You don't need to do anything. All you need to do is to replenish your spiritual energy."

Lu Ming nodded his head, although he did not know what was going on here, but since he needed so many people to maintain an array, it meant that there was a big problem here.

After saying that, Lu Ming quickly flew up to the 12th place and sat down. The moment he sat down, the spirit energy in his body was subconsciously sucked away.

Lu Ming immediately started to absorb energy from his storage ring. Finally, he was able to maintain a balance, when suddenly, there was a loud explosion. The originally bright and clear space was actually covered densely in black clouds, following that, everyone opened their eyes at the same time and shouted at the same time.

The dense layers of formations slowly began to fuse. From the top layer to the bottom layer, from three to one, ten to one, all the way until it reached lily one.

Suddenly, a figure soared into the sky. Lu Ming took a closer look, and realised that it was the principal of their Academy, this old fellow, who was standing in mid air with both hands forming hand seals. His eyes were wide opened, and his hair was disheveled like a madman.

"Seal!"

The dean gave a loud roar and stretched out his hand, which seemed to form many palms. He pressed down fiercely, and all the seals merged into one. After an explosion, everything disappeared.

These thousand people were all students of the school and were all at least eighth-grade. They were lying on the ground, breathing heavily.

Amongst the crowd, those who were still able to stand were the academy's teachers and principal. With a wave of the principal's hand, countless rays of light appeared out of nowhere and fell on each and every student.

"Teachers of the various divisions, bring the students back and cut off this memory." The dean ordered coldly.

"Yes."

All of the student's memories were cut off, but only Lu Ming looked carefully in front of the Principal when he was looking for Lu Ming, and said with a bit of a blaming tone, "You brat told you to take a month off, and you really only had one month left. You can't come back earlier."

Lu Ming was confused. He was scolded for no reason, and he did not know what was going on.

"How is it?" The elder walked over to look at the principal and asked.

"It should be fine. I've added the seal again. This time, it will be maintained for at least another 20 years. However, I'm afraid it'll be difficult next time." The Headmaster sighed and said.

The elder laughed and said, "Old brother, what are you worried about? After 20 years, they will already have grown up. When that time comes, their strength will definitely surpass ours. At that time, we will be able to easily seal this place. "

Lu Ming could not help but ask suspiciously, "Principal, Clan Elder, what exactly is inside?"

The two old fellows who had lived for who knew how many years looked at each other, then smiled and said, "Fear is sealed inside."
