Su Yang transmigrates to the interstellar era and becomes a rare healing guide. Interstellar Chinese medicine has long been lost. Without guides to soothe them, sentinels often lose control when their mental pools run wild, becoming expendable assets on the battlefield. While stranded on a remote planet, she encounters a squad of sentinels suffering from severe mental contamination and on the verge of losing control. Rather than relying solely on a guide's mental power, she uses the long-lost Chinese medicine's diagnostic methods and treatments to try to stabilize their frenzied mental landscapes.
