"Xuan·Jie" appeared suddenly, with no trailer, no official, or even a producer. It is not a product of modern technology at all. It seems to come from another world. It will suddenly appear in people's commonly used electronic devices. Even if you don't open it, nothing will happen. However, when someone actually opens it and tries to play it, they will be sucked in by it and play with a super-real experience. Only when the game is turned off will the player be released again. It became popular all over the world in a short time due to its unique gameplay. "Xuan·Jie" is very strange. How strange is it?

This has to be done by all countries, and all the experts have to give way in front of their own country's national team. What is the game difficulty of "Xuan·Jie"? It's very simple at first, but then... Hehe, try to let a baby fight a Titan?
