The Fantasy Cultivation Upgrade System was usually composed of a series of cultivation missions and challenges. These missions and challenges would continuously increase the strength of the cultivator and allow them to gradually advance to a higher level. The following aspects needed to be considered when constructing a cultivation upgrade system: 1. The strength of the cultivator: The strength of the cultivator is the foundation of the cultivation upgrade system. It is necessary to improve one's strength through various methods, including cultivating martial arts, improving spiritual power, improving physique, and so on. 2. Missions and challenges: Practitioners need to complete a series of missions and challenges. These missions and challenges will continuously improve their strength and at the same time, they can obtain various cultivation resources and experience. 3. Skills and equipment: Practitioners need to constantly improve their skills and equipment to enhance their combat effectiveness. This might include learning new martial arts, obtaining new equipment, increasing spiritual power, and so on. 4. Interpersonal relationships: Practitioners need to establish various interpersonal relationships, including making allies, defeating enemies, interacting with NPCs, etc. These interpersonal relationships can provide them with more resources and support. 5. Growth curve: A cultivator's growth curve should be a smooth curve and not a process of rapid increase or decrease. In the process of growth, cultivators needed to maintain patience and continue to work hard to continuously improve their strength and skills. The fantasy cultivation system needed to be constructed according to different novels or anime works, but the above construction principles could be used as a reference.
