The Thorn Guide: How a D-Rank Outcast Became the Most Coveted Healer

Xie Yuan was the academy's biggest joke—a D-rank Guide who couldn't link with anyone. Three years of failure meant one destination: back to the slums. Then fate throws her into the path of Yan Shu, the elite S-rank Sentinel spiraling into deadly mental collapse. Desperate to survive, he seizes her in a forced link—only to discover her secret. Her spiritual entity isn't weak; it's a vicious thorn that strikes back against any intruder. Now the most powerful Sentinels are hunting for the "useless" Guide whose touch could save or destroy them.
