Upgraded cooking skills, upgraded chess skills, upgraded painting, upgraded Dugu Nine Swords... Upgrade your cooking skills to LV4 and learn the skills of the chef... Upgrade Dugu Nine Swords to LV10, and realize that there is a way to win without any move... Eh! Why am I selected by Infinite Space? I obviously have a system and they still let me enter the space.
