The time progressed to the final years of the Ming Dynasty, where the yang waned and the yin grew, each year colder than the last. In the winter, even the Jiangnan region saw snowfall, and Tai Lake began to freeze over.
The "Water and Fire in Balance" project, initiated by Shi Feiyang, kicked into operation.
Ling Hun and Cui Wugu personally carried the True Sun Fire to various places to replenish the warmth, a process so subtle that people couldn't perceive it, for any greater force could bring disaster.
Disciples from the Snow Mountain Sect Daoist Temples cooperated, continually pushing back the ice line. Where to stop, neither Ling Hun nor Cui Wugu had any idea. Every hundred li they moved could influence the survival of countless beings. The karmic responsibility was great, so they dare not decide on their own and had to consult with Shi Feiyang.
Shi Feiyang told them flat out, "Push the ice line past the Yellow River!"
