The water in the Heavenly River rolled up into a tidal wave and roared continuously, while the thick spiritual clouds gathered in the sky and covered the sun. Boundless sword rays from a large spiritual beam shined down on a figure who was sitting cross-legged under the beam. The sword rays penetrated into every part of the figure, and their power was overbearing. It continually tore the figure's flesh apart and tortured him.
The figure was Mu Chen.
He had been sitting there for two weeks and had withstood the scouring of the majestic sword rays. He had received umpteen cuts in every part of his flesh and bones, but after each cut, his body recovered with the help of his Dragon-Phoenix Body. The cycle kept repeating itself.
Under such torturous training, if one was not determined, he would have been mentally tortured and given up long ago. He would then lose the great opportunity that the Heavenly Emperor had given him.
