Because he knew the strength of Yao Shen and the Xuanyuan Great Ancestor, if it were just a regular illusion, it would mostly be destroyed by the power of the two battling.
Thus, Ling Shen made the illusionary space completely sealed, sparing no effort, and even he himself could not detect the outside world when he was within the illusionary space.
But he had never imagined, despite all this, that there would still be someone who could dissolve his illusionary space from the outside.
Logically speaking, even if Yao Shen and the Xuanyuan Great Ancestor worked together, they shouldn't have been able to do such a thing.
"Who is it?"
Ling Shen, realizing something was amiss, stared coldly at the gap slashed open by the blade.
Whoosh!
A figure swiftly flew into the illusionary space, appearing beside Xuanyuan Tuo and Xuanyuan Wan'er.
"Xiao Tuo, Wan'er, are you all alright?"
"Great Ancestor, we are fine!"
