Shi Huayun is a person from the Immortal Realm, knowledgeable, and she is also incredibly intelligent and bold. She quickly guessed the truth.
When all impossibilities are discarded, whatever remains, no matter how improbable, must be the truth!
So, can Shi Hao control time?
Shi Huayun was startled. Time is a supreme rule that even the Jade Immortal must revere and dare not touch, for fear of angering the heavens and earth, which can easily obliterate the Jade Immortal.
Yet, now a Great Sacrificial Heaven can control time?
Even if it's just for a moment, just a tiny bit.
How did this young man from the Mortal Realm cultivate to the point where he can control time rules that even the Jade Immortal hasn't mastered?
"Shi Hao, why must you do this?" she said lightly, "You must know, even if you succeed, once you enter the Immortal Realm, your master can act without any scruples. Do you think you can contend against a Jade Immortal?"
