Fairy, Please Let Me Draw My Sword

Su Chen traveled through the world of Xianxia and obtained the golden finger of "Drawing out the sword makes you stronger". But all the fairy swords, magic swords, tyrant swords, and king swords in the world all recognized their masters. If Su Chen wanted to quickly increase his cultivation level by drawing the sword, it would be as difficult as climbing to the sky. Fortunately, he knew very well that he could win if he stayed alive, so he pulled some mortal iron in the blacksmith shop every day to increase his longevity. Until one day, he met Qingli Sword Fairy Lingyao. Ling Yao: "I see that your understanding is quite good. Are you willing to join my sect and practice swordsmanship?" Su Chen: "Fairy, before I practice swordsmanship, can I pull out your sword?" Ling Yao: "?" ... Ling Yao: "This is the introductory swordsmanship of my Ling family, "Qingyun Jue". After you take it back, remember to practice it well and understand it as soon as possible." Su Chen: "To be honest with the fairy, I have learned..." Ling Yao: "???"
