The protagonist is caught in a hopeless fight against a newly hatched Bone Spider, realizing his current strength is insufficient. A system appears, offering a path to become a Rune Warrior by completing missions and allocating stat points. He uses the gained strength to defeat the Bone Spider by leveraging a gasoline fire, its known weakness, after successfully completing his first mission. The chapter ends with him realizing the limitations of the system, requiring more missions to truly access Rune energy and advance, also noticing an opportunity to profit from recovered runes.
