In which chapter was Liu's sword in Xianyang hammered out?

Chapter four. Lu Chen, dressed as a magic stick, wanted to tell Liu Xianyang's fortune, but he was beaten by Liu Xianyang. In the fourth chapter, he was scared to run for his life. Born in a cave, Liu Xianyang is generous, honest and indifferent. He likes childish Gui, who is a little older than Ann. His family is Chen's grave keeper. Liu Xianyang, born in the golden age of Li Zhudong in the old days, naturally bears some secrets, mysterious ancestral sword sutra and ugly scorpion armor, all of which prove that Liu Xianyang's background is not simple.
