The Great Zhou's Survivalist

Lin Bei transmigrates to Qingshi Town, becoming a collateral descendant of the martial arts Lin family. He finds this world too dangerous: the eldest son of the main branch casually kills a servant with no consequences; two factions in town fight, leaving dozens dead or injured, yet the authorities do nothing; demon beasts occasionally descend from the mountains to devour humans, and the locals take it in stride. Lin Bei decides: lying low is the key to victory.
