Light of Nirvana

Unknown genetic samples brought back by interstellar exploration were leaked, global biology mutated, and zombies became rampant. I'm just an ordinary high school student who luckily awakened the most basic F-level healing ability and struggled to survive in the ruins. In order to save people that day, I was almost swallowed by a mutant, but unexpectedly discovered that my healing technique could purify the zombie virus. As the news spread, forces from all sides swarmed in and wanted to keep me as private property. In the chaos, the strongest man who controlled the natural disaster of the undead blocked the way, raised his pale fingers lightly, and thousands of corpses knelt down. He lowered his eyes and spoke in a low and dangerous voice: "Purify someone for me, otherwise——" I nodded tremblingly, but was stunned when I saw the face in the ice coffin. That was clearly... The me who was declared dead three years ago. (This is not a brainless article, please read it patiently.)
