The House Repairman Awakens and I Am Invincible with the Sound of the Undead Ringtone.

In the seventh year of the apocalypse, there are many people with supernatural powers in the ruins of Gray City. Qi Yan is an otaku casual cultivator who makes a living by taking orders and has awakened the low-level power "energy perception". One night, I picked up a talking bone cat Asha, and a strange ringtone sounded in my head - touching the undead can unlock memory fragments and turn them into ashes of experience to strengthen yourself. He wanted to lie down, but because his golden finger was exposed, he was chased by killers, targeted by the princess, and set up by businessmen. The quirky alien girl Feng Ling breaks into their lives, and the three of them are forced to get involved in a shocking conspiracy of resurrecting the undead. Fighting wits in the arena, breaking blood contracts, and dealing with powerful people, Qi Yan uses the sound of a bell to peek into the secrets, and uses ashes to become stronger. The ghosts in this world are not scary, but the human heart is hard to guard against. Fortunately, he is not alone.
