Guardian of Intangible Cultural Heritage

With the slow recovery of aura, many intangible cultural heritages have begun to show supernatural power because of the profound history, emotions, beliefs and cultural "aura" they carry. People who master intangible cultural heritage skills can also use this power. The protagonist accidentally obtains an "intangible cultural heritage system", which allows him to gain "craftsmanship value" and "aura points" through learning, practicing, and spreading intangible cultural heritage. Craftsmanship points can be exchanged for skill proficiency, materials, tools, and even lost techniques; aura points can activate the "artifact spirits" or historical memory fragments contained in intangible cultural heritage items for use in combat, exploration, or assistance.
