According to Long Yangjun, she only selected the few most in pain and resentful miners and taught them the "Serenity Arts" so that they could get rid of the incessant and unforgettable agony.
In order to teach the rather complicated techniques to the miners who were uneducated, she had to teach them by using the methods of telepathy and directly stamped the arts into their heads through the transmission of brainwaves.
It was only a minor experiment at the beginning, but she greatly underestimated the potentials of the hominoids below the ground. The Serenity Arts and the methods of telepathy were spread among the miners like a wildfire. They were disseminated from this tunnel to that tunnel, from one mine to ten mines, from the mines to the geothermal factories, and from the geothermal factories to the assembly lines on upper levels or even the financial districts even upper above.
