Lin Tian did not expect that the old master would be so powerful, able to suppress the yin energy immediately. However, the next step was not going to be easy. The compressed yin energy became stronger, persistently clashing with the old master at the knee boundary.
Additionally, Lin Tian noticed that although Mr. Yun's thigh was free of yin energy, it still showed no signs of life. Was it destroyed by the yin energy, or suppressed?
Lin Tian furrowed his brows slightly. It seemed that Mr. Yun's condition had been deteriorating for some time; otherwise, the vitality in his legs wouldn't have disappeared. In other words, simply expelling the yin energy from his legs wasn't enough. Mr. Yun still couldn't walk and a way to restore the vitality in his legs was needed.
Restoring vitality is not easy, akin to reviving the dead, a defiance of the natural order.
