The people of Sun Island who were being watched as if they were thieves did really want to further cooperate with the Dark Mystical Palace. There were several countries on Sun Island, and although the country named Ri was the leader, they weren't really nothing but sexual violence.
Apart from the self-produced androgynous slaves and other modified humans, as well as the elementary-grade cauldrons they researched with Hehuan Island, they had deep research in biological weapons.
The people of Sun Island had experimented on the battlefield many times. Even when they were defeated and retreating, they did not forget to bury poison gas bottles. They had an extremely thorough understanding of the human body because they had dissected the bodies of the prisoners of war one by one, studying the reactions of living people to various biological weapons.
