Apocalypse's Strongest Fusion Master

Ten minutes before death, Chen Wu is reborn with the Strongest Subordinate System—and everything changes. He may be ordinary, but his subordinates are anything but. The Hundred-Year Yama executes his will without question, while Adris, a zombie who devours her own kind, stands as his lethal vanguard. In a world overrun by the undead, Chen Wu doesn't fight alone—he commands an army of the impossible. When survival means power, and power means fusion, who will dare stand against the master of apocalypse?
