Wu Yun couldn't understand why others traveled through time very high, but he started as a beggar? What's even more terrifying is that he didn't even have a golden finger! He asked for a year's meal until... an old beggar with less finger insisted on accepting him as his disciple. He said that if he followed him, he could make a dragon with a slap! Brief version: This is a story of a black-bellied otaku walking in various martial arts worlds and becoming the strongest hero. The beginning: The Legend of the Condor Heroes!
