You Know One Things . Master Yao Lao Is Elite Dou Zun level Warrior . While Yun Shan Is Just an Elite Dou Zong . If This Time Master Get back his Real Strength He can Easily Waived out entire Misty Cloud Sect Just By Using His Hand Movement . It's because of There are Too Much Power Gap Between them . But Currently Master in his Soul Form . That's why He just Have Elite Dou Zong level power . Note that :- Each Stage have 9 sub levels and When you Tuched the 10th step of Sub level you will break through the previous Stage and Step On next Stage . Therefore There are 9 sub level of Dou Zong . Which is called Dou Zong 1 star ..... Dou Zong 9 star . And Each Sub level have 4 sub levels Which is 1-Entrance, 2- Intermediate 3- Advanced 4- Peak . Which means When you Choose to become a 3 star Dou Zong level to 4 star Dou Zong level warrior you have to passed through these Sub Level of Stars after that You will reached next Star.. I think You already Know How Much Power Different between Master Yao Lao And Yun Shan . If you put Master Yao Lao Real Strength . But Currently Both are in True Elite Dou Zong level .
Everything is right but Yao Chen is not a dou zun he is 1 star dou sheng ( in the last fight with mu gu Yao Chen already reached dou shen level but got betrayed and died with his own student's sword Edit : 😊😊😊
