Modern migrant worker Lin Xiao accidentally crosses into ancient Huangtu Village, finding he can hear the old locust tree and old objects speak. Using "living objects" like old bamboo slips, coarse pottery bowls, and wooden pole scales for guidance, he helps tofu shop girl Su Wan improve tofu, channel mountain springs, and break the wicked bully Wang Fugui's water-cutting, sales-blocking, and arson conspiracies, ultimately uniting the villagers to defend their rights and making a choice between returning to modern times and staying.
