"What is meant by stepping outside the Three Realms and within the Five Elements,"
refers to places outside the Three Realms and beyond the Five Elements as a world of complete emptiness.
In any world, the fundamental basis must involve the Five Elements: metal, wood, water, fire, and earth.
From one comes two, from two comes three, and from three comes everything that exists in the world.
The unity of the Five Elements divides into two as the Five Elements of Yin and Yang, which then transform into heaven, earth, and humanity, thus giving birth to the world.
Outside the Three Realms and beyond the Five Elements, other worlds exist—this much Yibai knew very well, as Red Moon World was precisely such a place.
However, he had never actually reached the so-called realm beyond the Three Realms and the Five Elements.
Now, it was Yibai's first time coming here.
Yibai gazed at the emptiness around him and fell into contemplation.
