Purify Apocalypse

After reaching the first level of Qi refining, he was expelled from the sect. After ten years of waste, one day of awakening - purifying the bloodline. Zombies are rampant and spiritual energy is exhausted. Others hide from zombies, while I kill zombies to level up. One zombie increases its cultivation level, and one mutates and unlocks skills. Pursued by the Qingyun Sect? As much as comes, so much is purified. Under the old capital, the truth about the apocalypse three hundred years ago is hidden. When the aura of chaos sweeps across the wasteland, purification is the only solution. This is the end of the world, and it is also my place of cultivation.
