The Healer is Fine, so Go Save the World!

Lacking both mana and divine power: the temple’s half-wit Sun Yihan. Thanks to the system, he became the only healer in a party of warriors. However, failure to complete the quest will worsen his health, and excessive use of his ability will lead to him vomiting blood. He was simply trying to cure others to the best of his recently received ability. The warriors, working under a misunderstanding, refused to be treated. Meanwhile, the cracks in the world increasing in size. Abnormalities that only Yihan can see appeared. A healer who wants to heal his warriors, and the warriors who want to protect their healer.
