The Lord of Demon City, President Xuanyuan Wuji of Xuanyuan Corporation, didn't actually set out for Zique Continent from Immortal Peak, which is variously regarded with 'awe' by the gods, following his wife Empress Shangguan Linlang (Linda).
As a native of Zique Continent, how could Shangguan Linlang (Linda) not have her own special 'path' to travel there?
Of course, the Empress wasn't aware of the method from the beginning, she too gradually 'explored' to arrive at such a conclusion.
And it was the Western Demon God Satan who inspired her with such an epiphany.
The 'special passage' that Shangguan Linlang (Linda) relied on was none other than the domain overseen by Satan—the Endless Abyss.
That place had once been where the Lord of the Western Paradise, Yehe Huarong, had 'briefly trapped' the Empress Shangguan Linlang, Heavenly Emperor Yu Siang, Lord Yama Shangguan Qingtian, and Satan.
