Arthur was almost killed, but miraculously survived, showing unusual strength. He is forced to go on a dangerous mission, during which he finds out why and whose fault the infection broke out. Not because of a virus or mutations, but because of reasons previously unknown to science, and Arthur was the one who could control them like a skilled puppeteer with puppets. This could give Arthur everything, including world domination, and Arthur himself did not know whether he would take advantage of this opportunity.
