When Yi Yun only had a single Divine Lord Royal Seal, he was able to defeat Ghost Ming who was also a Ghost Thearch.
And now that Yi Yun's cultivation level was that of a half-step Godly Monarch, he was completely different from the past!
In fact, after Yi Yun refined the Myriad Form Shura Pills, he already had the means to defeat the Luo King and Ghost Doctor. However, he was in Heaven Fey City after all. There was Ruins Emperor and the two Fey Patriarchs to consider.
The shock and awe rendered by the two Fey Patriarchs made Yi Yun hold back.
By appearing weaker than he was, he could deal a fatal blow at the critical moment.
Previously, apart from Lin Xintong and Shan Ling, no one, even Blood King and Jiang Xiaorou, knew of Yi Yun's true strength.
This also caused Ruins Emperor to make a horrendous judgment error. He thought he could use the hand of the Luo King to maim Yi Yun during his weakness from transcending the Heavenly Tribulation.
