Qi was everywhere.
Ye Qiu felt the Qi between heaven and earth, the tiny ions adrift in the air, and sensed their liveliness, their pulsations.
True Qi was the same as the Qi existing between heaven and earth, diverging yet converging. Ye Qiu could sense the movement of tiny dust particles and gradually discovered that True Qi, too, had its trajectory during diffusion.
Heaven naturally nourishes all beings while no beings reciprocate to heaven.
Conversely, a Martial Artist would contend with heaven, unwilling to remain an ordinary person.
A Martial Artist, especially those who have reached the state of True Qi, far surpass ordinary people in vision and spirit. To break through in martial arts, one must break through oneself, and True Qi is the Martial Artist's ladder against the heavens.
Ye Qiu aimed to climb to the peak of that ladder by thoroughly understanding each step.
