Epic Narrative of the Grimace

Su Yuanyi comes from an immortal but anonymous clan who fight the shadow spirits formed by peoples' negative emotions, to save people's souls from being devoured. After being injured on a mission, the human boy Tang Yao was assigned to be his servant. Conflicts and misunderstandings ensued. "Maybe Mr. Ice Cube should talk like a human being for once." "If you've lived for 500 years then you might understand." Can the two work together and come to an understanding, in order to heal others and heal themselves? (Source: Tencent, translated)
