Zhang Yi was trying to gain time to see if any miracles were happening and his divine immortal rage technique activated, he had already understood all about this technique, yet had failed to learn and activate it in any way.
Something was missing that he didn't know what it was, but if he didn't activate now and he got rid of the restrictions both he and his wives would die, beyond them this whole continent would be destroyed and the army of skeletons would form again.
Luckily after entering the realm of mortal tribulation, his qi was dozens of times higher than before, and Zhang Yi had already gotten rid of his clone technique when the twins appeared in the fight and his qi was full again.
