Li Xuan naturally wouldn't be careless enough to directly follow Amaterasu Omikami into Takamagahara.
He first let Takamagahara open its barrier, allowing his army to be stationed, and then gradually took control of all the strategic points within Takamagahara. He then sent Master Zhongliu and Divine General Taichong Yuanchen among others inside, who suppressed Takamagahara's core areas.
Only when Takamagahara was completely open, like a woman who has been stripped of her clothes, lying flat and allowing others to dispose of her at will, did Li Xuan step inside.
This so-called 'Takamagahara' is a void much like the Heavenly Court of Xuanhuang, but its area is much larger. It extends two hundred and eighty miles from north to south, and three hundred and twenty miles from east to west. Inside are mountains of clear waters and beautiful scenery, even vast plots of tillable land.
