Dragons: the Ancients of Seer and the King of Battle

In 2020, Li Kongling, a college student taking online classes, traveled back to 1990, a soulless world where the extraordinary disappeared. At least, that's what he thought. When people are most content and carefree, a door will open beside you. Li Kongling has lived in this world for eighteen years. When he was at his most glorious, the door opened. "On June 6, 2009, a letter from Cassel College in Chicago ruined my football dream." So wrote Kai Grom-Lee, Champions League champion, Bundesliga champion, and DFB-Pokal champion. Since then, his life style has changed greatly: "Where are my teammates! Where are my teammates? Help me!" Lu Mingfei shouted to his classmates for help. "Who is talking about the wild history of Big Butt and the King of the Mountain on the Night Watch forum?" A certain level 10 junior sister was filled with hatred. "Word Spirit King's Power? Why is there still black smoke?" Instructor Flamel flipped through the ancestral Spirit Spirit notes and was very curious about someone's Word Spirit. "The naughty little naughty housekeeper of the Seer Lucio star base is at your service!" The super-powered nono shook his head and threw himself into the arms of the young dragon slayer. "You said... You are a dragon, right?" The boy who transformed into a dragon slayer licked his lips: "It seems that you don't understand much about us dragon slayers. In our world, the battle between humans and dragons can only rely on four times of restraint and bloody swords. We won't stop until you die!" This is the story of a boy who possesses the power of a dragon slayer and walks in the world of dragons.
