My Dao Companion Always Thinks They're a Substitute

Xie Zhiyuan has cultivated for so long that he feels his life is complete, without a single regret. Blessed with a one-of-a-kind pure yin constitution in the cultivation world, he makes rapid progress and treats tribulations like a sightseeing trip. His master is the sect leader of the foremost sect in the Immortal Realm, and his daughter is a sweet, adorable little darling. His cultivation partner is the little wolf-dog nephew-disciple he raised from childhood, with a loyalty rating of 100%. There probably isn't anyone in the entire cultivation world happier than him. Then one day, his little wolf-dog partner gets drunk and clings to him, sobbing his heart out. Xie Zhiyuan is baffled. The partner blurts out what he really thinks while drunk, accusing him: “I know you've always treated me as a substitute for Master.” Xie Zhiyuan is shocked! Who the hell spread that rumor to his partner? Not long after, his senior brother and his partner's master, who had been missing for hundreds of years and whose face Xie Zhiyuan can't even remember, suddenly returns. His senior brother takes his hand and says tenderly, “I never knew you cared about me so much, little brother.” Xie Zhiyuan: “...Sorry, I didn't know either.” His partner: “...I'll let you two be together.” Xie Zhiyuan: “I didn't! I haven't! Just listen to me explain!” From then on, Xie Zhiyuan's life is thrown into chaos.
