NFT burning in the land of Azollite

You need lower model NFTs to level up your components and buildings; For example, in order to be able to make a Type 2 drill with a higher power, you will need to burn two drills with lower levels. This mechanism makes the NFT cycle always in need of supply and demand; People in higher levels may need NFT, which is achieved by a person in a very low level, to level up. Due to the scarcity of NFTs, they are always in circulation and people will need each other to develop their business and games.
