"Metaverse" is a network composed of always online virtual environment. In this network, people can interact with others and digitized objects while operating virtual avatars, experience immersive virtual reality, and feel the combination of large-scale multiplayer online role-playing games and networks. The meta universe can also refer to a shared and lasting virtual space, which can be imagined as a digital mirror of the real world, without any constraints and restrictions. Facebook CEO Mark Zuckerberg once said that the description of meta "It is a reified internet, where you are not only browsing content, but in it." In the development of the meta universe, chain game is the perfect carrier to experience its concept and show the meta universe world in the way of game. Then the blockchain technology integrated game was discovered, and the NFT in the chain game was considered by people in the industry as the key to pry open the mysterious door of the meta universe. NFT can enter the meta universe world of virtual social networking through the chain game interface, and all NFTs may enter the meta universe and have dream-like linkage with the meta universe.
