“Good news, good news! Reliable sources from the Celestial Palace say that Sang Ning, Heaven's resident bully, has been arrested.”
“Tell us more.”
“I hear that the little scatterbrained immortal Sang Ning abducted the Buddha's chosen disciple!!”
Sang Ning, who has been throwing her weight around in Heaven, has finally gone too far. To give the Buddhists an explanation, the Jade Emperor punishes the two immortal heirs who were fooling around with Sang Ning by sending them down to the mortal realm to undergo trials. But the Buddha's chosen disciple volunteers to take Sang Ning's punishment, so all three descend to the mortal realm to undergo trials, while Sang Ning is left behind in Heaven. As the ringleader, she also loses her memories of the three of them.
The Jade Emperor thinks this will ensure everything goes smoothly, but he never expects the little scatterbrained immortal to get involved with the Buddha's chosen disciple all over again.
First, Sang Ning makes a bet with the Matchmaker: if she can change someone else's fate, then all lovers in the world will end up together.
Her first target is to change the ending of a villain who has been pierced by a thousand arrows through nine lifetimes.
Easy enough, except why does this villain get more and more useless the longer she raises him...
Her second target is Lin Yue, a hopeless romantic with a tragic ending.
Well, all she can say is that love is toxic.
The Jade Emperor: I agree.
He promptly decrees that immortals are forbidden to fall in love. Love is toxic, so away with it! Away, away!
…
Later, after being taken in by the Fate Immortal's sweet talk, Sang Ning somehow gets caught up in the Buddha's chosen disciple's nine lifetimes of reincarnation.
In the first lifetime, she is Sang Ning, a peasant girl, and he is Ji Yunsheng, a demon-slaying exorcist…
