Gao Wu: Honey, don't cry, I'm truly invincible!

Reborn back to the age of eighteen, Qin Su awakens a midlife comeback system. He initially thought the system was a joke, until it started issuing tasks.
[Ding! Mission issued: Thirty-eight years old, working overtime and staying up late, irregular schedule, neglecting and declining martial arts skills, the host's body is already overdrawn. How can you embark on the path of martial arts again without a strong physique? Please train diligently to strengthen your body and lay a solid foundation for your future martial arts journey.]
[Task: Do 10 pull-ups.]
[Difficulty: Five stars (For an average office worker who lacks exercise, even completing a single pull-up is difficult, but those who succeed possess great perseverance. Host, I have high hopes for you!)]
[Reward: Foundation in Martial Arts.]
Qin Su looked at the system task with a strange expression.
He is now eighteen years old and a martial arts apprentice-level martial artist, at the peak of his physical condition. Unlike his previous life, he has not become too decadent, causing his martial arts to decline and turning him into an ordinary person.
At this point, he could do not only ten pull-ups, but also a thousand in one go, all with one hand.
Is this task really not a freebie?
