While Others Cultivate, I LVL UP In My Sleep Using The Dungeon System

Shinka needed to return and they had already bid each other farewell, but Adam stayed staring at her, curious to find out how exactly she was going to return to the underworld.

She could see that and knew that it was a secret of the underground, but after forming a Soul Contract and speaking with him for such a long time, she trusted him and had no reason to hide it.

There was something that Soul Creatures and especially the Death Corps were skilled at, and that was creating portals and wielding space itself.

Although Shinka wasn't particularly skilled at it and couldn't be described as a skilled, capable or notorious individual within the Death Corps, all members of the Death Corps were capable of forming a single portal.

To do so, they used a Space Crystal that was given to them by the Death Corps and after the secret incantation was recited, along with large amounts of Soul Power being poured into it, a portal back to the underworld would be formed.

Each Space Crystal was linked to a different portal room in the underworld and since the underworld was an independent, secluded and unique realm, using such means was the only way to get to and from such a place.

Space Crystals were used for single teleportation from one space to another, while portals would use such crystals and energy in the atmosphere to do the same thing.

It was one of the most advanced forms of cultivation technology and was what was used to cover large distances in an instant and also move between plains and the Mortal Realms.

On the 64 positive Mortal Realms, only the ancients and the Evil Cultivation Organisation had access to such things, but even with them, it was impossible to reach the Immortal Plain.

They would only be able to teleport with it to an intersection, either the Mortal Intersection or the Upper Intersection, but both of them were filled with dangers and negative creatures that were almost always hostile.

It was also risky and dangerous to use a portal or Space Crystal without a pre-set location, as unless one was extremely skilled and versed in the use of such cultivation technology and versed in warping through space, they could end up anywhere in the universe.

And if one was extremely unlucky, they could also end up outside of the universe, where only the endless void existed and nothing could survive in the void.

All teleportation required was the necessary resources, a capable welder and a pre-set location, but the Space crystals that allowed one to enter the underworld were unique and only distributed to the Death Corps.

Those crystals could only be found in the underworld and were linked to the space of the underworld.

There were Death Wraiths and those from the Death Corps that ended up being killed or lost their Underworld Space Crystal in the other plains, however, the Death Corps would do anything to get them back and make sure that no outsiders had a way to get into the underworld.

All the sacred places and treasures that needed to be protected and secured in the underworld, along with all the secrets of how they operated, could all be taken and revealed if one was able to get into the underworld.

The existence of such things was incredible for Adam to think about and it made the transportation methods that humans came up with, such as planes and cars, seem incapable.

Adam had learnt such things about teleportation and Space Crystals, also sometimes called Transportation Crystals, from the system and from Shinka, but what he saw Shinka do, shocked him greatly.

She didn't seem to have any item or Space Crystal with her and also didn't recite any form of incantation.

She merely closed her eyes, used her Soul Force and pushed her arms forwards, and as she did so, a small black hole, that was large enough for her to fit through, appeared before her.

Adam was unsure if it was only due to his Soul Vision being activated that he was able to see the portal and was also unsure whether it would be possible for an ordinary person to see it.

However, how she formed it went against everything he had been informed about how people were able to move through space, and although the portal was shocking, being able to form it without the assistance of some sort of Space Crystal was even more shocking.

Jumping into the portal, it disappeared as soon as she did and Adam observed that there was a split second before the portal closed, meaning that if he was fast enough to use the Step Skip Skill, he should be able to follow her through the portal.

However he had no desire or need to do so and doing that would only cause himself and Shinka unneeded trouble, but it was a valuable piece of knowledge for him to know.

The small instant of time that it took for the portal to close would be impossible to observe, let alone use, for most, unless they were an extremely powerful cultivator with unbelievable speed.

Adam was only able to detect and estimate such things because of his great perceptivity, rapid reflexes and unbelievably high speed.

However, he still was curious as to why and how Shinka was able to form the portal, and after the change in the system, along with the increase in Adam's maturity and mental fortitude, the system would be willing to share most knowledge that he needed with him.

He had been exposed to so many eye-opening and overwhelming revelations, yet had always remained calm and sane after hearing them.

The past year was not only one where Adam's body, cultivation and knowledge improved by leaps and bounds, but also his mental and emotional fortitude, clarity and stability.

Hearing Adam's questions and sensing his curiosity, the more accommodating system began answering all the questions he had bouncing around within his mind.
