Ancestor Sorcerer and Blade Emperor both admitted that even they had to redirect part of their heart energy to resist against this illusory realm.
"Currently, his illusory realm could already affect us. If Dong Bo Xue Ying could become a Cosmos God using the Dao of Mirage, his illusory realm would be frightening. By then, even we have to redirect much of our heart energy to resist against it." Ancestor Sorcerer transmitted a message. Blade Emperor agreed with it. A Cosmos God who reached his realm using the Dao of Mirage might not be formidable in direct combat, but in a war between many Cosmos Gods, this illusory realm would be of great help.
"A technique that targets the soul. He is purer than Heart Imitation in this aspect." Blade Emperor said. Heart Imitation Religious Master was his subordinate.
