The Spider at the Top of the World - Episode 9

The episode opens with a man encountering a strange, possibly poisonous fog and suddenly surrounded by dangerous beasts. He fights and defeats a group of Cursing Frogs, absorbing their Evolution Points to gain new skills. As he collects more points, including from the frogs he vanquishes, he upgrades his Enfeeblement skill from beginner to advanced. Confident in his progress, he aims to reach C-Rank by accumulating 300,000 Evolution Points. However, just as he advances, an unexpected threat or complication emerges, leaving the outcome uncertain.
