Junior Disciple

Yu Qingwei, the esteemed senior brother of the Azure Sky Sect, a role model admired by all, one day crosses paths with an outwardly gentle yet inwardly cunning junior disciple from the outer sect-sharp-tongued, persistent, and scheming.

The first time they meet, the junior tricks him, stepping over him to claim first place in the sect's competition.
The second time, in a secret realm, the junior sweet-talks him into handing over a precious opportunity, leaving Yu Qingwei humiliated.

Enraged, Yu Qingwei seeks revenge, only to inexplicably receive a kiss instead. From then on, the junior becomes noticeably more obedient in front of him.

It isn't until the junior ascends, leaving Yu Qingwei behind and cutting off all emotions, that he realizes the truth-the junior had been cultivating the Path of Heartlessness.

Hurt as he is, Yu Qingwei later uncovers a greater deception: the junior had ventured alone into the demonic domain to seek a rare chance of survival for Yu Qingwei, fully prepared to never return alive.

Fortunately, Yu Qingwei manages to bring him back.

Now, Yu Qingwei braces himself for the endless stream of lies that are sure to follow. His junior is like a flower-a poisonous one. Once picked, it ensnares you for a lifetime.
