At the mountain summit, Li Yifei was now trapped in extreme danger. During the time Sophia was rescuing someone, Li Yifei had lost count of how many times he was hit by Yanagio Inujiro and sent flying. Each time he was knocked away, Li Yifei felt as though all his strength was dissipated, every part of him ached, and more importantly, Yanagio Inujiro's black energy was invading his body.
The black energy seemed to carry the aura of death, burning his body and his True Qi. The burnt areas gradually became powerless.
Unless Li Yifei summoned his True Qi to dispel the black energy, he could not regain control of those parts.
Yanagio Inujiro seemed in no hurry to kill him. After knocking Li Yifei away, he'd stop, then mock and provoke him. Once Li Yifei stood up again, Yanagio would strike him several times more.
