When the world was ridiculing him, he faced a terrifying fountain with rules to kill people, but he calmly opened the "Book of Mountains and Seas" and said, "Oh, Gu Huoniao, we are an old acquaintance." After easily containing it, he backhandedly used the anomaly as a weapon and threw it into the American live broadcast room! "Sorry, my rules are: understand, contain, and then use!"
