Li Yangyang was once a koi spirit who had cultivated for a thousand years beside the Jade Pool, blessed with fortune and auspicious luck. By chance, she formed a bond with a transmigration System and traveled through countless fictional worlds based on films and television shows.
The System takes her through all kinds of these worlds. Blessed with top-tier luck, she leaves misfortune behind and brings good fortune wherever she goes. Her journey is smooth sailing, and she always turns danger into safety.
No fixed couple.
In every world, she meets someone new who makes her heart flutter, and every romance is a sweet, mutual devotion.
With the System by her side and good luck on her side, plus endless tenderness and special affection, the little lucky koi travels happily through countless worlds, spreading sweetness wherever she goes.

You can write a special forces/fire phoenix couple pairing with Lei Zhan.
Not bad, there's only one world so far.
