You think it's a lucky opportunity, but it turns out to be a butcher's knife.
Don't go around picking up or accepting free opportunities in secret realms. You might find a knife hanging around your neck instead.
Teng Pukui was unlucky enough to have an overwhelmingly powerful opportunity show up uninvited, one she couldn't refuse. She thought she'd be happy and grow stronger from then on, but she kept getting nowhere.

She thought the one waiting in the treasure-house tower would be the sect's guardian deity. Little did she know it was a deadly blade lying in wait for her. Teng Pukui, oh, Teng Pukui, you really were born without luck.
Shatter their prejudice.
The sect's infamous deadweight smashed through everyone's prejudice and discrimination at the sect tournament. Right before their eyes, she broke through to the next realm, then leaped three stages straight to perfection, leaving the disciples watching gritting their teeth in frustration.
Every morning when Teng Pukui woke up, she would tell herself: "You have to remember, there are no free opportunities in this world, and no one loves you for no reason. The person who loves you most is me! Me, Teng Pukui!"
