The story goes like this: Mc lived as an adventurer for like a decade just solo grinding on weak monsters, cuz no one wants to pt with him with his "useless" time-based ability, where the mc can only stop time of one living target. When he finally upgraded his ability, he was now able to save his childhood friend he froze with said ability. That's about all I can remember... Does someone remember this? Does this have a novel?
This might be it: yakudatazu skill ni jinsei o sosogikomi 25 nen imasarar saikyou no boukentan midori kashi no akia.
slight typo there but I think you got it right. Yakudatazu Skill ni Jinsei o Sosogikomi 25-nen, Imasara Saikyou no Boukentan Midori Kashi no Akira
