On the day Lu Chen received his dismissal, he discovered that all the "spiritual energy" in the city had been stolen.
He is a forensic scientist from the Department of Physics and is used to using Fourier transform to take apart everything. When the seven pulse frequencies - 7, 11, 19, 31, 43, 57, 73 Hz - lit up like seven lights on his chest, he understood: the so-called cultivation of immortality is just that someone takes away the pulses of a living person and connects them to a mother abyss called "source".
Six provincial adapters, one hundred and twenty-seven miners, bodies that were dismantled into parts and flowed into the body of the researcher.
Lu Chen did not become a disciple and did not survive the calamity. He took seven lamps to the abyss, stayed in the abyss, and taught the source to learn "not to eat".
When the main gate at the deepest part of the frequency layer loosened, he finally transformed himself back into the ever-bright 31 Hz.
