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

"Bellow these 64 worlds of the Mortal Plain is the underworld that has the soul cycle along with death wraiths, death gods and many other mysterious beings living there. It is almost impossible for a living human to get there and even if they did manage to get there, their body and soul would be destroyed within an instant" 

"There is a soul cycle and more souls are always being produced, but souls are also being destroyed by the death beings that I have mentioned, so in most cases, there is always balance and equilibrium. There are still many other things that occur in the underworld and many more mysteries, but what I can say is that some are able to reincarnate, but for most, their memories and past lives will be destroyed and they will start again in a new body. Souls of some beings that are too dangerous to let go and have cultivated their souls are imprisoned in the underworld and the host should try his best not to offend any death beings or attempt to enter the underworld until he is capable enough"

Everything Adam was hearing seemed too unbelievable to be true, but he knew that Ava wasn't joking and the more she said, the more he realised he didn't know much about how the universe truly was.

[Me, go to the underworld. I would like to stay as far away from that place as possible] thought Adam to himself.

"Well Adam, knowing you and your reckless behaviour, you will probably end up going there somehow. Most likely because of the soul sea that is there. It is where the souls of all the dead are taken by death wraiths before being processed and finding a suitable body for it. That can take a while and I wonder if one of your friends died, would you attempt to steal their soul from the soul sea and whether you can even get enough power and knowledge to be able to do so. At the host's current level, even measly mortal cultivators in New York can defeat you quite easily, unless you go wild and unleash your full power. But after unleashing your full power, you will end up revealing cultivation to the world and getting yourself captured or killed since you will be massively weakened" stated Ava directly, not wanting Adam to become arrogant or overconfident.

"Your progress is good and steady, so do not become disappointed with yourself. But the things I am telling you now are for you to know and not for you to try and explore or use, otherwise you will be merely drawing the attention of beings you cannot mess with and getting yourself killed" 

Hearing that, Adam knew that anything outside of his current world was too much to think about and until he had a strong foothold in his current world, he shouldn't think about anything else.

"Now enough about the underworld. It is a place that even the ancients might not know about and definitely cannot attempt to go to or mess with. I will move onto what you had previously realised"

"Just like the positive side of the Mortal Plain, there is a negative side that is filled with beasts, demons and humanoid creatures like goblins that could be classified as beasts, but had gained a sentient level of intelligence. The intelligent creatures developed and became stronger much faster than other beasts and in most cases, demons are more powerful than beasts and there aren't many demons on the negative side of the Mortal Plain" said Ava.

"This is because, above the Mortal Plain there are other plains that are much larger, and have much more powerful beings, that would be considered as gods by your current standards. Demons, immortals, dragons and all kinds of other godly creatures exist, but in higher plains, so that host doesn't currently have to worry about coming across any of them or facing them at the current moment"

"Above the Mortal Plain, there is the Upper Intersection, which is an incredibly large flat plain that needs to be crossed over to reach the Immortal Plain. In that plain, almost every single being is a cultivator and most of the cultivators there have surpassed mortal limits, but aren't immortals yet. Above the Upper Intersection is the Immortal Plain, where obviously, most immortals chose to live and the Immortal Plain along with the intersection are almost infinite and contain all kinds of mysteries and wonders"

The more Ava spoke, the more Adam realised that the universe was much wider than he knew and he was currently merely a small ant struggling against others that were also insignificant beings.

It opened his eyes to what the universe truly had to offer and made him feel as though everything he was feeling or had seen was so trivial and that all he could do was strive to be great and explore more of the universe.

"There is also a Lower Intersection between the Mortal Plain and the underworld, which is one of the most dangerous places that one can go as there is no law enforcement or great powers that are there. It is a barren land filled with killing, death and battle between all kinds of different creatures and most wouldn't dare to go to the Lower Intersection. Not only was the Lower Intersection dangerous because of the beings there, but the environment was very harsh even for cultivators and bellow it was the underworld that had very strict rules and would eliminate any being that dared to enter or get near"

"As the host could probably imagine, there are great powers and rulers in the underworld along with the Immortal Plain, which are the great plains. The underworld is in most cases is only accessible to beings of death that can also reproduce. They also have lives in the underworld and cooperate with the great beings of the Immortal Plains, as if a war broke out between them, the entire universe would be in turmoil. There are many things in this universe that the host still will find out for now, but this is just the system opening the host's eyes to the truth"
