Yun Youwei, a second-year graduate student in chemical engineering, ends up in the cultivation world as a cannon-fodder female supporting character born with sealed meridians. On the day she is expelled from her sect, a periodic table lights up in her dantian. It turns out the world's spiritual energy can be broken down and recombined.
From then on, everything changes.
Other people use spiritual energy to stoke their pill furnaces; she calculates the enthalpy of reaction. Others draw talismans and chant spells; she writes chemical equations. Others endure lightning tribulations; she throws alkali metals into the sky. Ever heard of a hydrogen explosion?
On the run, she picks up a taciturn young assassin, rescues a demon girl being hunted, and forms the most unreliable team in the entire cultivation world.
By the time everyone catches on, the good-for-nothing has already blown a hole through the ceiling of the whole world.
