Disillusionment 1: Fatal Return to Zero

There is a planet in the vast universe called Htrae. Disillusionment is one of the major catastrophes. Whenever there is extreme imbalance in an era, disillusionment will come to maintain balance. Species assimilated by disillusionment will turn into spirits of disillusionment and become the main force of the disillusionment side in the current and subsequent eras of disillusionment. Disillusionment has created seven keys of joy, anger, sorrow, joy, evil and desire, and will select a specific target to incarnate into the corresponding phantom. Each phantom has the ability to destroy the world. The Seven Keys summon the illusion of love through a mysterious ritual. The other part of the species that has adapted to the disillusionment is called the qualified person, and the smaller part of them who have awakened supernatural abilities are called the guests. The last disillusionment broke out in the first year of the Christian era, and mankind temporarily won at a great cost. Since then, humans have been exploring ways to overcome disillusionment, but what they don't know is that the more they try to overcome disillusionment, the more they destroy the balance.
