Absolute Choice
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 only fear is that the Celestial King will not dare to participate
"To the Celestial King and King Leonis:
Why should wars be fought between soldiers? Do you dare to fight king against king? This King only wishes for a life-and-death battle between the three kings, with life and death determining the outcome! If This King were to die in battle, the Infernal domain will surrender! Conversely, if you were to unfortunately die by This King's sword, please withdraw your troops! This King has penned the challenge. Do the both of you dare to fight? —The most cowardly Infernal King in all of eternity!"
The two letters with the same content were separately sent to the Celestial domain and Transcendence. It might have been done unwittingly or it might have been done deliberately, but the contents of the two letters were quickly revealed. It proliferated in the three domains, causing every commoner on the streets and the soldiers to know of the letter's content. A flurry of discussion broke out because of it.
