From the Start as a Serf: Rising to the Throne from Snake Catcher

Buren transmigrated to another world and became the most endangered kind of snake-catching serf.

With crushing taxes, his father badly injured while catching snakes, and monsters at the gates, his family was on the brink of collapse when he suddenly awakened his golden finger:

[Buried Relic (White): The owner's hidden treasure remains in the collapsed house.]

[Wounded Serpent King (Green): After losing the battle of the Serpent Kings, the old Serpent King fled with severe injuries and is hiding in a cave in the ravine on the northern slope.]

[Vanished Insectoid Warrior (Blue): An Insectoid warrior capable of using its life sac to cultivate top-grade magical potions is about to fail its transformation.]

Three times a month, he randomly discovers opportunities nearby. Relying on them, Buren rises step by step to become a professional and a contracted pet warrior, climbing from serf to lord and onward to the very top.
