I can't exit the abyss?

In an unknown abyss, where all the strongest species existed even Gods and Demons can't conquer, a human successfully entered but died immediately because he can't stand the strong pressure of mana even though he's fully prepared. The body was supposed to deteriorate but his body started absorbing the mana in his surrounding for an unknown reason. After an unknown amount of time, the body started to regain a new consciousness.

He doesn't know who he is, but his head started to ache for a few minutes and the memories of the owner of the body entered his brain. He learned that his name is Zero, the strongest mage and the strongest swordsman in his world. Based on the memories, Zero discovered this abyss and he kept it secret about its existence. He also learned that the owner of this body tried to enter the unknown land and immediately died because the body can't handle the pressure of the abyss.

Zero woke up and he can feel his power surging after absorbing mana. Even though his body is absorbing the mana for a very long time, the mana in the abyss is still the same like nothing happened. When Zero finally reorganized his thoughts he tried to find the exit to the abyss.

'But why the fuck is there is no exit?'

Zero can't even see a glimpse of light so he used [Light Magic] that he learned from the memories of his body. Based on his memory there are 12 levels of magic. When you reach the 7th level, you can be considered as a grand mage and that is the highest level human can reach.

The recent owner of the body is the very first in history who attain the 8th level. Because of that, his head grew big and decided to enter the abyss, but unfortunately, he didn't even last a minute.

Zero stood up and he learned that he is in a cave. Fortunately, there are no monsters inside the cave. He walked slowly to see what is outside of the cave. When he finally saw what is outside of the cave, he saw Ancient Dragons, Demons, and different mysterious creatures that even the previous owner of the body doesn't know. What he saw outside is a world with a red sky, the smell of blood is reeking everywhere, and you can see monsters fighting everywhere. His mind went blank because based on the memories of the recent owner of his body, this kind of creature only exists in the legends but why now there are too many of them? If one of these creatures entered the human realm, it's the end of humanity. So he tried to calm down and start to think about how can he get out of this hell.

He tried to find where the previous owner of the body used to enter the abyss but unfortunately, the entrance no longer can be found.

He found no more answer, and he decided to clear this hell to find out how to exit. So he decided to go outside the cave to measure first his strength.

After an hour, he found out that he can fight those wicked creatures and every time he killed an enemy his body will automatically start absorbing the corpse and making it his power.

'What the hell is this ability? I can't remember the previous owner of this body using this?'

'If I have an ability like this, I am confident that I can exit.'

He muttered to himself.

After absorbing the body of the ancient dragon, his whole body started to ache and the mana in his body started to overflow, he tried to stabilize his body and mana and after five minutes, his body calmed down. "WHAT THE F*CK IS THAT? IM LUCKY THAT THERE'S NO ENEMY WHILE MY BODY IS IN THAT STATE" he unintentionally shouted. He now started exploring the unknown abyss. After absorbing he can feel the changes in his body and learned that as he absorbs more monsters, he will get stronger.

After a few months, his body doesn't now feel any pain when absorbing the enemy. And he can now control if he wants to absorb the body or not. Zero eats the monsters that he killed and cooks them using [Fire Magic]. Most of the monsters he eats have a very high poison. But, Zero's [Poison Resistance] is very high that most of the poisons will not work on him. [Poison Resistance] is a passive skill. As its name suggests, it's a skill that nullifies poison.

After an unknown amount of time, he can see the improvement of his power.

"I'm exploring this abyss for a very long time and I still can't find its end, is there no end to this?"

Zero said. Zero's mana pool is now absurdly large compared to the first time arriving here. He killed all enemies in his way and most of his enemies didn't have intellect and only the Dragons can think but their pride is so high that they cannot allow a mere human to roam the abyss so Zero killed them. Every monster he meets, he's asking how to exit the abyss but none of them answered so they all died.

While walking he found a lake and this is his first time seeing a lake so he go for it. When he saw the lake, he saw his reflection and learned that his body is quite handsome.

'Ohh, so this is what I look like?'

He's tall, has long black hair, a nice body build, and has good facial features. While looking at his reflection, a very big fish with red eyes jumped in the water trying to attack Zero.

"Ohh? Waiting for your prey to let their guard down huh?"

When he saw the fish he summoned a sword made of [Darkness Magic] and started attacking the fish. And just like that, the fish died.

"Thanks for the lunch" he muttered.

Zero started using fire magic to cook the fish.
