In terms of their positions, Luo Zhen and Gilgamesh were undoubtedly on the same side.
Luo Zhen's goal was to repair this Singularity and lay a new foundation for the Human Order, so he had to recover the "Holy Grail" of King of Magecraft Solomon. He also had to defeat the "Three Goddess Alliance," which threatened this era.
Gilgamesh's goal, meanwhile, was to protect Uruk and preserve humanity's flame so that human history could continue into later generations. Thus, he also had to defeat the "Three Goddess Alliance."
Under these circumstances, while Uruk had yet to collapse, Luo Zhen could take the opportunity to investigate the "Holy Grail."
