Chen Yu, after completing the extraction of the Nether River, saw something with his "last glance" that he still couldn't bear at this moment.
Rubbing her forehead, Kojo Kyoko couldn't help but start recalling what she had just seen, although it exceeded her current capacity to handle, the knowledge it contained was something every Necromancer would find irresistible to peek into.
Of course, those mages who only know how to throw fireballs, pursue Forbidden Curses, and crave destruction won't do so because they do not seek knowledge but only violence and destruction.
What Chen Yu saw, to put it simply, was not complicated, he just took a "glance" at the whole of Japan, not in the sense of looking down at the land from space, but seeing the entire Japan from a Multiverse perspective, which included not only the territory where mortals lived but also the so-called Divine domain that ordinary people and even transcendent beings could not spy into.
