Rise of the Demon God

From what he had seen so far, he apparently had one day of time to prepare for the next wave. With each wave, he received slightly more time for rest. 

"Your performance was really good. You have a pretty good grasp of space." 

"Hmm? You're finally back?" Long Chen recognized the voice of the old man. 

"How many waves are there! When will this trial end?" Long Chen asked, standing up. He glared at the old man. 

"End? It already ended on the fourth wave." The old man smirked. 

Long Chen looked blankly at the old man, wondering if he was serious. 

"If it was over ten years ago, then why did I spend so long fighting hundreds of waves? Why didn't you stop them? Why didn't you tell me? Do you like playing with me?" Long Chen asked, frowning. "This place is so stupid!"

"You're wrong. I didn't do it because I liked seeing you fight or I wanted to waste your time. I did it because it was fun to see you fight, and I wanted to see how far you could go without giving up," the old man responded, smiling. 

"You certainly didn't disappoint me," he added. 

Long Chen rolled his eyes. "Just for your ten minutes of fun, I lost my ten years. Should I thank you?"

"It doesn't matter. I'm done here. I'm leaving. Give me whatever credit you can and send me out."

"Not so fast. I don't think you should leave empty handed after what you showed me. Your Spatial Comprehension reminded me of my young days. And since you put on such a good show, let me give you something in return."

"Something in return?" Long Chen frowned. 

"Yep. Something that might be very useful to you after the performance of yours. I think you'll need it," the old man exclaimed. He casually waved his hand, making Long Chen disappear. 

"Have fun and make the best use of it," the man muttered, shaking his head. 

Crack~

Cracks started developing in space all around him until the entire space shattered, merging into one massive space instead of many layers. 

"Where is he?" The Heavenly Emperor's voice echoed the empty space. 

He hadn't been able to find Long Chen inside. 

"Where is who?" The old man asked, curious. He didn't understand what the man was talking about. Why was he here?

At first, he thought this guy was simply here to destroy everything he created for some reason. That's why he sent Long Chen to take the most precious thing that he left in this place 

"I'm talking about Long Chen! He is the one who was taking the trial here. He was also the last person here," The Heavenly Emperor responded. 

"I know Genso; you left your remnant of soul behind. And that was when you were upset with me. So you won't be willing to answer me that easily, but don't make me force you! Tell me where he is! I need him!"

"You need a mortal? That's very intriguing. The Heavenly Emperor needs a weak human cultivator?" 

"Human? Are you sure he was a human?"

"Hah, who can be more sure than me?" The old man responded. "Anyway, the person you're looking for isn't here. He finished his trial, and I sent him out of the Tower. You won't find him here!"

"Why are you messing with the space here? Why did you slow down the time here?" The Heavenly Emperor asked. 

"Is that even a question? Because I saw you coming. And your aura was going to make the space unstable. I wanted to finish the trials before you came in so they won't be affected," the old man answered. "If that's all, you can leave. I still have to repair the space here from the start for the next set of challenges."

The Heavenly Emperor didn't leave just yet. He observed every place inside the tower, making sure that Long Chen actually wasn't here. 

He glanced at the old man once again, sighing. 

"It's good to see you once again. Enjoy your eternal stay here." The Heavenly Emperor turned around and started leaving. 

"How long?" The old man asked. 

"What?" The Heavenly Emperor looked back. 

"How long has it been since I died in the outside world?" The old man asked. 

Since he was only the remnant of the soil that was left to oversee this tower, he didn't know what had happened to his body outside. 

"A very very long time," the Heavenly Emperor responded before he left the tower. 

He looked at the top of the tower, seeing the color of the name was indeed different. That meant Long Chen wasn't inside.  

"Which one is he?" He asked the Heavenly Warrior that had seen Long Chen. 

All the people that had come out from the tower were stopped by the Heavenly Warriors, who weren't letting them move. 

"None of them is Long Chen," the Heavenly Warrior replied. "He isn't here."

...

Long Chen's whereabouts were a mystery for these people. However, none of them knew that Long Chen was inside the tower. The only difference was that he wasn't in the Dark Tower but the training tower. 

Moreover, he wasn't on any ordinary floor but underground in a special room which was right under the room where he had trained yesterday. 

"What is this place?"

He observed his surroundings. He was inside a room that was only three meters wide. There was nothing inside the room, including no exit. 

There was, however, something special in this place. A sphere of white light was floating in the middle of the room. 

"What is this?" He stepped closer to the sphere of light but didn't touch it. 

He didn't want to repeat the same mistake as last time.

He observed the rest of the room first, mostly focusing on the walls and the carving on them. 

He also tried using his Divine Sense to not only notice even the most minute details of the room but also to see outside the room to find where he was. 

His Divine Sense failed to see anything outside the room, being blocked by the walls. 

"Just what is this place?"

He also tried using his Law of Space, wondering if he was still inside the trial World of the tower, but it didn't work. 

"It looks like I'm outside the tower but still trapped somewhere."

"The old man did say he was giving me a gift. He didn't look like he was lying. Why would he even? If he wanted me dead, it wasn't hard for someone like him. So it couldn't be a trick to kill me."

He decided to take the risk.. He walked to the sphere of light and touched it.
