The ointment nation is home to many Onmyoji professionals, and breeding ghost creatures can enhance their combat abilities.
Therefore, there are many places within the ointment nation for breeding ghost creatures, with Tokyo City having three of the largest ghost breeding grounds.
The Onmyo Holy Palace, the Dog Emperor's Royal Palace, and the Yasukuni Divine Latrine.
The Yasukuni Divine Latrine had already been bombarded into ruins by Zi Liyuan with the Magic Crystal Cannon, the war-criminal spirits inside were all annihilated in a sneak attack, and their spoils of war had been thoroughly looted by Edward and his vampires.
As for the Onmyo Holy Palace, Zi Liyuan knew his strength was insufficient, and he didn't dare provoke it.
The Dog Emperor's Royal Palace, normally with formidable defense forces, was even able to call upon the support of the Wokou Army within Tokyo City at any time, making it unthinkable to target this place.
