Elemental Summoning in Online Games

Li Hei, who had been doing nothing all his life, encountered a game crash during a daily online session. When he regained consciousness, he had returned to the place where his online gaming dream began 5 years ago. In order to make money and uncover the secret behind the collapse of the game, Li Hei once again entered "Ancient" and relied on the memories of his previous life to become a top player in the game.
