Han Yuankai not only was unharmed by Su Hanyan's Wind-Thunder Sword but also used the air's Thunder attribute Spiritual Power with his Thunderclap Step to rush toward the Misty World instantaneously.
In Han Yuankai's view, as long as he could enter the Misty World, he would hide anywhere, and the Sum Emperor would never find him.
Furthermore, the space within the Misty World was extremely unstable; especially after the constraints of the Misty World disappeared, the space started to show signs of collapse, leaving no reason for the Sum Emperor to risk venturing into the Misty World for him.
Seeing Su Hanyan turn into a bolt of lightning disappearing from his sight, Su Hanyan furrowed her brows, absolutely unwilling to let the man who killed her Honored Master escape from her sight so easily.
The next moment, Su Hanyan once again commanded her sword to chase in the direction Han Yuankai had fled.
