A world filled with heroes with superpowers. A world attacked by calamity fiends. A modern world filled with wonders and dangers. Shi Xiaobai, a child from normal Earth, walked into such a world, proclaiming to be its king. But at the first signs of danger, he is forced to make a choice, one which he cannot refuse for time would repeat, making him face the choice again. He is not humble nor is he modest, but neither is he delusional. Yet, the Absolute Choice seems to make fun of him. Will the joke be on him or will he laugh at his opponents? There will be many watching his escapades, and there will be some joining him in his adventures. To see through the world and to grasp its truth, that is the destiny of the King.
The three large-scale 'Apocalypses' that nearly wiped out humans were composed of three parts. Firstly, it was the Original Sin of Calamity that existed for only half an hour. Secondly, the Seven Deadly Sins would wreak havoc for three days. Thirdly, all sorts of natural disasters like earthquakes, tsunamis, and volcanic eruptions would constantly occur.
The Original Sin of Calamity was no doubt the strongest existence. Although it was unknown why the Original Sin of Calamity would only exist for half an hour, it would be able to kill nearly all the strongest people in the human world in the thirty minutes. Ten thousand years ago, the pixie species which Kali was from had all its strongest figures annihilated by the Original Sin of Calamity, including her mother and grandmother.
