MTL - Since 1981 Health School - Chapter 433 a different diagnosis

When Jiang Cheng was told to return to a family that he never knew or had a relationship with, he had never expected to end up meeting a young girl, and eventually, her seemingly roguish brother Gu Fei, as a first encounter in the new city.

Anger issues was never a problem for Rio, but how can he say that after he swiped away his system in anger when the crystallization began on earth.With portals popping up and monster storming out of them how can Rio be expected not get angry at his lack of a level up tool.Armed with just an axe, as the days go by, Rio has a rapidly building peeve against his never present system and the last virtue on his list is tolerance.“System”“......... ”“System”“...…..”“Grrrrr!! Grrrr!!”With loud menacing growls the wolf like creatures approached, but Rio was busy looking for what spot in the room had better connection and would let him access his system.“If you guys don't shut up, I'll kill you.”Normally, worlds undergoing crystallization should be struggling to get stronger and survive the brutal process but on earth it is different as they are rather focused on pleasing their brutal and unforgiving Tyrant

I, Zatiel, Abyssal Lord, Ruler of Death and Destruction, Nightmare of Dys, have AWOKEN!!!!!.

His life contains events that can shake the universe:
-Fighting against Tiamat, Creator of Evil Dragonkind, in the first circle of hell, while billions of demons and devils butcher each other beneath them
-Start a World War against the Heavenly Race, and transform himself into a Golden Sun while he slaughters their greatest warriors, the Archangel.
-Enter the Final Gate and fight against the Outer Gods.
-Tearing the nine levels of Baator during his battles against the Prince of Evil, Asmodeus.

With his memories as a ruler of the Abyss and a Universal Existence, Zatiel will rise again.

On that day, due to the outbreak of an unprecedented and abnormal event, 41 students from class 2-7 of Shiromine Academy are summoned to a different world, one full of magic.

Separated and summoned inside a vast dungeon, where the only way to escape is to head to the deepest area, they are given the power of a Divine Protection 『Vocation』 as the only means of survival.

While some of them are brave, some just do whatever they want, and some harbor treacherous intentions, they all aim to capture the dungeon.

In this place, one person gained a 『Vocation』 whose skills are unsuitable for combat, attendance number 19, Momokawa Kotaro.

A boy with a small and lean build from the Literature Club wasn’t blessed with a physical ability, swordsmanship, or strong magic, rather he only had the 『Shaman』 vocation to rely on.

After being driven out of the group and left behind by his powerful classmates —– his survival instinct starts running at full throttle!

Pushed to the limit of survival in the different world’s dungeon, what starts with trusting and loving each other soon ends in killing and betrayal.

The most beautiful and gruesome battle royale has raised its curtain.
