The Start Was Decided, but I Became the Only Variable

Qi traveled through "Eternal Continent" and awakened the only rare skill - and then was told: the skill bar is permanently fixed, and you can only use one skill in this life. "It's useless." "What a pity." "Just call 666 from now on." Everyone thought he was a joke. Until he walked into the wilderness and raised his hand towards the LV2 wild boar—— Defense: 12→Defense: 0 [Probability of paralysis: 20%] → [Probability of paralysis: 100%] One knife, instant kill. Later, someone asked him: You only have one skill, why should you challenge the rules of this world? Lin Qi looked at the data flow in front of him and smiled: "Because my skill is called [Data Erosion]." "And your so-called rules-" "To me, it's just a string of numbers that can be modified." When the whole world thought that I was destined to die by the rules, I became the only bug in the rules.
