CHANCE by Whiskey Flowers

Chance has spent his life as an indentured servant in the Durian Empire, where magical contracts bind servants to powerful nobles. He secretly possesses rare sight magic, allowing him to see hidden truths, look through solid objects, glimpse the past, and briefly see the future. When a noble stranger buys out his contract, Chance becomes free and sets out as an F-ranked adventurer, determined to earn enough money to free his parents. His abilities grow rapidly after he discovers that powerful monsters can release magical essence, but a terrifying army of invisible Goblins and brutal Lizardmen threatens the entire empire. Chance must master his growing powers and fight alongside his newly freed family to survive—and prove that his freedom has made him stronger than those who once owned him.
