If one day he were to devour all the races between heaven and earth, then he would be able to attain the realm of a Daluo Jinxian of the Primordial.
In order to achieve the Tao, the Human Demon had no choice but to travel across All Heavens and Myriads of Worlds, under such circumstances, he naturally did not wish to stay and guard the North Sea within the Three Realms.
Fortunately, the Human Ancestor was sensitive to other's wishes and saw the Human Demon's dilemma, and took the initiative to take over the task of guarding the North Sea. He had nothing else to do anyway, and his next move was to find a place to cultivate, striving to enter the realm of the Saints as soon as possible.
Wherever you cultivate is still cultivation, whether it's from Emperor Wa's Palace or the North Sea.
"With the Human Ancestor present, the North Sea will be safe!"
