Jin Chuiduo's healing process wasn't as simple as 2-1=1, nor a cancelation of mutually equivalent values. Through the intermediary use of Divine Skills, she targeted the consumption of her own Cultivation to heal the injuries within Chu You's body. Both parties harnessed Sun Awe energy, with the only difference being one at the initial stage and the other at Great Perfection, meaning there wasn't a massive gulf between their realms.
Thus, Jin Chuiduo used a small amount of Sun Awe energy to heal Chu You's injuries, with her Shen Zang realm rapidly repairing itself, leading to an increase in health and a natural recovery rate for Great Perfection energy beginning to rise.
As Jin Chuiduo's forehead began to glisten with fine beads of sweat, she withdrew her healing hands and smiled at Chu You, "Now it's your senior sister's turn."
