The opening of Mirror Sword Mountain occurred late at night, and it has been rumored that someone saw the Netherworld Gate of Mirror Sword Mountain open on a special moonlit night.
This rumor was not false; Mirror Sword Mountain was indeed the so-called Netherworld Gate, but it led to a sealed Immortal City instead of the world of the undead.
When the ninth realm began, Chu Mu's eyes were covered and his Soul Sense was sealed. He was led along a long winding path before finally being brought into Mirror Sword Mountain, entering the hidden domain gate between the roots that stretched across the sky.
Chu Mu had no idea how the Netherworld Gate was opened; he only knew that his body passed through a very special space filled with a strong dark aura. It felt as though he had entered a land of death, giving the impression that there were no living beings, yet there were moving objects.
