Huayu Gong is the last god in the world, and his profession is to "collect debts" from immortals and demons.
She traveled through the three realms, asking for the "love", "joy" and "courage" that had been borrowed but not returned overdue.
Her client list is long:
The immortal who owes the "joy" of all people, the sword master who takes away his "love and thoughts"...
And her biggest creditor is Xianzunlou Tingxue, who owes a huge "love debt".
