The vast expanse, encompassing countless Heavenly Regions, had even begun to raise doubts in Jian Wushuang's mind.
Did the Great Si Region truly have boundaries?
Now, receiving precise information from Yu Chang's mouth, it made Jian Wushuang feel a slight unease.
If the Great Si Region alone was so vast and boundless, how would the ultimate Great Yan Domain manifest before his eyes?
And where would Xuan Yi, Old Master, and the others exist in this ultimate Great Yan Domain, and in what form?
Just as Jian Wushuang was lost in thought, Yu Chang spoke slowly, "You've seen it for yourself. Not all the voids in the Heavenly Regions can give birth to Planes. The closer you get to the boundary, the less likely it is for Planes to exist."
"The boundary of the Great Si Region, where the Emperors can expand, is the limit. Here, even the power of creation cannot exist, and further expansion has no meaning."
