Age of Disaster: God of Killing in Two Realms

When a zombie disaster breaks out, Jiang Chao, who is struggling to survive, accidentally travels to a strange world of immortality. He has no spiritual roots but meets the elder of the Artifact Refining Pavilion who appreciates his talent in instrument refining (apocalyptic metallurgical craftsmanship). He has just gained a foothold and wakes up to find that he has returned to his home in the apocalypse. The shuttle between the two worlds begins here. In the apocalypse, he used his physical training to challenge those with supernatural powers, and relied on the talisman formation to fight his way through the tide of corpses and humanity. In the realm of cultivating immortals, he relied on his murderous nature honed in life and death to defeat all the geniuses. Without spiritual roots, he uses weapons to enter the Tao and proves the Tao through killing. This is a dead end, and it is also his road to the top.
