"What is this thing?" Miles looked at the weird substances the ghosts turned into after they were killed. It looked like bluish-purple jelly. He dared not to touch it, but still collected them and placed them in a nylon bag.

"I have no information in my database about it." Coin reported. He couldn't see the ghosts while they were 'alive.' But now that Miles had 'killed' them, he could see the substances. Luckily, the battle was only bothersome and only wore down Miles. It wasn't dangerous. After resting for a while, Miles followed the path. Soon he arrived at a door.

"W-What is this?" He asked in shock. What stood in front of him was a giant door and a statue. The statue looked humanoid but made of metal. There were two pairs of wings white in color and the eyes of the statue looked like dawning suns. The face of this humanoid was compassionate as if he was looking down on people and accommodating them all. There was all-encompassing love and kindness on the metal, cold face. The creator must be one hell of an artist.

There were words at the base of the statue but it was in a language Miles didn't know of. The letters were strange. Just by looking at them, he could feel the message they were giving off. He could feel despair, hope, pain, bravery, and belief of incoming better days.

"How strange." He couldn't help but mutter. He was hundred percent sure that he didn't know those letters, but he still could understand what the writing was about. It was as if the letter themselves could emit what they wanted to convey. Miles only saw this kind of situation in runes, but they were magical carvings made of energy. Mother AI said that even before monsters invaded, energy was accessible to ancient races, but before that, before the portal opened and monsters invaded Portal World, native races couldn't use advanced techniques as the sheer amount of energy was sparse.

Ignoring the message for now, since he couldn't figure it out by thinking, Miles focused on the door. It was as tall as the room, which was 12 meters. The metal the door was made of looked quite strong. He thought even with his full force, he couldn't even dent the metal. Thus, he turned to his trusted partner to open the door.

"It is locked, I am trying to enter, but the code is the same as mine, so I cannot override it." Coin said as writing flew through the virtual screen. He was using thousands of combinations every second to open the lock. "Before you say, I tried 1234. It is not working."

"Too bad. Try 'password' instead." Miles shrugged as he looked at the door in detail. It wasn't a piece of art like the statue. There were no carvings, engravings, or decorations. It was plain black and it looked majestic even in the dark environment. Miles felt like staring at endless space when he looked at the door as if there were sparkling stars blinking at him each second. And there was a sun that was about to dawn on the horizon, at the same time on the other end, a moon was about to set.

"Can it really be?" Coin muttered while Miles was lost in his imagination. In the next second, the heavy-looking doors split open and a beam of light pierced through the dark, much to Miles's eyes' protest. "How can that be?!"

"What was it?" Miles asked as he tried to look inside.

"Nothing, let's go inside." Coin mumbled.

"Right." Miles looked at the interior and gasped in shock. There were many things inside but all of them were giving the same creepy energy. There were stretchers, glass containers with different bodies inside, and different tools that very much suggested that this place was once used to experiment on living things. "What is this place?"

"Seems like some kind of laboratory." Coin said as he floated out of Miles's arm to attach a nearby computer. A cable stretched out from its body and hacked the computer. "There are lots of logs about experiments. Most of them are titled, "Immortal."

"Immortal?" Miles asked as he went over to look. "Can it be that the person who created this lab was searching for immortality?"

"Might be." Coin lackadaisical answer. He was reading files at record speed. Seeing that there were millions of files, Miles ignored the fast-flowing screen and started to look around. At one point in time, there probably were creatures on all of the stretchers. But now, all that had remained were residues of living beings that eternally dirtied the once white sheets.

Glass containers on the other hand were different. Maybe because of the fluids inside, but the creatures inside were still well preserved. Some were monsters but there were some that looked like humanoid creatures. Miles wasn't sure if they were native races of Portal World or humanoid monsters.

Miles gasped in shock. The creature inside the container had a lean body. It looked three meters tall but his figure was skinny. Miles wasn't sure if it was because he was held captive or if he was always skinny.

He approached one of the glass containers and looked at the metal label. The language used was the same as Coin's, thus Miles could still read it.

"Aksel Hoyer, Demon Race. Superpower: Endless Hellfire. Any attacks he uses can eternally grow by sucking energy from the atmosphere. Although he cannot use it to revive his cells, his energy carries the endlessness attribute."

"This is the Demon Race?" Miles muttered in shock. He knew Zall had uncanny resemblances with the mysterious Demon Race, but he didn't think it would be so similar. This creature, except for the thick figure Zall had, looked almost the same.

Now knowing these creatures were native races of Portal World, Miles took a look at the other containers.

"Ike Kenji. Iron Race. Superpower: Regeneration through metal. Can eat metals to heal his body. Although he cannot live forever, the ability allows him to heal himself by eating metal."

"Leela Panja. Buddhiva Race. Superpower: Eternal Light. Her body can suck the light from celestial bodies to strengthen and heal herself. Although not immortal, the way her powers use energy allows her to live through most lethal injuries."

"Natalia Ofir. Shaman Race. Superpower: Symbiosis. Can attach herself to any tree to live together. Even at death's door, she can heal herself by attaching a tree. Through the usage of her superpower, she lengthened her lifespan at least four times the normal lifetime of her race."

Miles looked at the tens of containers and different superpowers. All these people were already deceased, but at their time, they were all extremely powerful. The more he read the more shocked he was. All the six native races of Portal World had at least one member in glass containers.

Just as Miles was about to look at a container, he noticed not far from him, at the end of the line was a container without a label. The empty space of the metal label was glaring, so Miles approached to look at the creature inside. The person had pointy ears and long hair. His skin was greenish-yellow. He was from the Shaman Race. He had seen many from the same race. Miles was about to turn and check the few others he skipped when something unbelievable happened. The person in the glass container opened his eyes and looked at Miles.
