I Level Up Even in Desperate Situations

Number one swordsman, also known as the “Little Sword Saint” of the Ninth Star Temple, faced a tragic fate. During a battle against an onslaught of extraterrestrial beasts, his father, known as the “Great Sword Saint,” heroically sacrificed himself.
In a cruel twist of fate, Sword Number One was ambushed and killed, carrying with him boundless resentment and unanswered questions. However, the wheel of destiny had other plans for him. He awoke in the body of an Earth child with the same name. Not only was this new life a lowly prisoner, but he also possessed the lowest-grade lineage of a worthless plant-based bloodline.
