Another World: It's Just a Blood Pack, Don't Be Too Exaggerated.

Traveling through the world of superpowers, Lu Wuwei awakened the most rubbish F-level blood-recovery talent. Everyone regards me as a team mobile power bank and ridicules me that I can only be a tool in my life. I spread my hands: It's just a blood pack, please don't be too exaggerated. Later, they learned that this humble blood pack had evolved all the way to the ceiling SSS level, and the entire other world was about to crawl at my feet.
