Reincarnated as an Energy with a System

The 5 Apostles walked through the portal with some missing memories. They remembered Ning most of what happened, or so they thought at least.

They remembered the beasts they fought and even the dragon that appeared. Then they remembered Ning punching that dragon and then… was that how it all happened.

They didn't really have any reason to get suspicious of their own memories, so they walked out without a problem.

Ning was about to walk out as well, but he sensed that the space in there was about to collapse. He didn't know what would happen in the case of such spatial collapse, but he was sure that if that were to happen, the beasts in here would certainly die.

Now, Ning didn't care for the beasts that were in there. But he cared about the SS-ranked Mana stones inside the beasts. After all, this was the first SS-ranked dungeon in the world, so he had to get the mana stones.

Otherwise, it would be a waste to leave without them.

Ning used his spatial powers to slow down the crumbling space as he quickly went through the entire dungeon taking away the beasts.

He had no time to kill them and take away their mana stones, so he left that task to Sorlus who was inside his world at the moment.

After finishing, Ning quickly went through the portal as the dungeon collapsed behind him.

When he got out, the portal disappeared as well.

"Oh, you're out. Thank god," Park said quickly. "I thought something happened to you."

"Hmm, no nothing happ—" Ning paused as he looked at his surrounding. A bright light shined from all around them… but why?

"The hell?" he thought. "How is it already night?"

"No idea," the Apostles said. "It was already past midnight by the time we came out too. And you took 15 more minutes than us."

"I took 15 minutes?" Ning asked suspiciously. He turned to look at the portal behind him that was now gone forever.

'Wait… time difference? In a dungeon? But that was supposed to only happen when…' Ning paused when a thought came across his mind.

Not long after coming to Earth, he had asked the system about the situation with the constellations, and during that time he had learned something.

The reason why there was so many dungeons was so that the mana in the other worlds would permeate to earth, and when that happened, it would create a stable dungeon that would work as a portal between the two universes.

Ning didn't believe that this was such a portal or anything, but he did believe that it was the start of one.

If left alone, any and all dungeons would continue to evolve until they all become portals to other worlds.

Given that it was an entire Galaxy at play here, Ning could only wonder how many different worlds could freely enter Earth and terrorize it.

'And those damn constellations are waiting for this exact thing, aren't they?' he thought, remembering the system's words.

'So that makes it 3 universes that I've been to,' Ning thought with an amused face.

Ning quickly teleported back to his Uncle's house before dropping Sorlus off. He hadn't breathed for a while, so Ning didn't want to keep him inside.

"White, you here?" he called.

White, who had been watching TV all night quickly turned around. "Master? You're finally back," he said.

"Not yet. I'll be back in a bit. Look after him for me, okay?" he said, pushing forth the tiny blue-haired child.

White sniffed the air twice and put on a disgusted face. "I don't like his smell. He reminds me of something," he said.

"Well he is a dragon," Ning said.

Saphandra quickly flew out too. "He's a dragon? This kid?" she asked.

"Remember Derel?" Ning asked.

"Derel… oh, right. Dragon," she said. Unlike Ning, she had no eidetic memory, so it was a surprise she remembered at all.

"Master, what is he?" Sorlus asked while pointing at White.

"He's a tiger," Ning said. "Now, don't go fighting you two. I will be back in a bit. Saph, look after them."

He was about to leave but stopped. "Oh right, here," Ning quickly created a bracelet that went around the Dragon's wrist.

"You will be able to understand other people's language with this. You can talk to these two now," Ning said. "As for explaining what happened to you, I will do so once I return."

Ning finally left the house, leaving behind the dragon, the tiger, and the spirit to talk with each other.

He arrived back at the Dongmyo shrine site where the Apostles looked at him curiously.

"You can teleport? Where did you go?" Park asked.

"Sorry, sorry. I needed to relieve myself so I went to some remote site," Ning said.

They talked for a minute or two before the director arrived at the location.

"You guys are out?" he asked before even opening the door of his van. He quickly walked out and checked.

"Oh thank god you are all fine," the director said. "I was so worried that you had all died in there. Why did you spend over half a day in that dungeon? Was it that hard?"

"Uh… no, director," Soo-Yun said. "We actually only spent maybe 15 minutes at best. I have no idea how it turned to over 12 hours outside."

"15 minutes? In that dung— wait, where's the dungeon? Where did it go?" the Director asked. His relieved mind panicked again when he didn't see any portal in the area.

"It's gone," Ning said. "The portal was destroyed once we defeated the beast inside."

"No way! That can't be true," the director refused to believe it. However, the lack of a portal was very convincing.

"I don't think this is something you have to be worried about, director," Ning said.

"Huh, what do you mean?" the director asked.

"If I'm not wrong, and these Apostles should ask their gods to confirm this too,  any dungeon that goes to SS-rank or above becomes a one-time dungeon that will be destroyed if defeated."
