The Heavenly Dao is weakening, the spiritual energy in the world is scarce, and the world has been artificially divided into the mortal realm and the cultivation realm.
As spiritual energy grows scarcer with every use, the cultivators of the cultivation realm are all living in fear.
Ye Sirong has an outstanding talent bestowed by Heaven, yet instead of cultivating properly, he takes up chemistry like an ordinary person.
Then, by accident, he manages to create spiritual energy...
Everyone: ...Thank you, savior!
At first, Ye Sirong says he wants to go to the mortal realm to study chemistry.
A group of senior cultivators: "Why go there? There's barely any spiritual energy, so it's completely unsuitable for cultivation. Don't waste your exceptional talent!"
"Don't go. It's so chaotic out there. Earthquakes today, floods tomorrow. How scary!"
Later:
-----"Good thing you went!"
-----"It's actually pretty great!"
