In Hua legends, there were always such plots——A marvelous sharp weapon was thrown into a well. Many years later, it suddenly turned into light or a dragon and flew away; After defeating some fierce beasts or animals, unrivaled figures gained marvelous sharp weapons.
There were so many similar legends. Zhang Tie had heard about them from his parents or Donder when he was young in Blackhot City. Many similar legends were even recorded in ancient Hua classics.
Take this story in the "History of the Jin Dynasty" as an instance: Zhang Hua saw a sword qi in Fengcheng City; he then promoted Lei Huan as the mayor of Fengcheng City. Lei Huan excavated two swords, one for Zhang Hua, the other for himself. After Zhang Hua passed away, Lei Huan carried the two swords with him. When he was passing the Yanpingjin Lake, the two swords sprung out of his waist sides and fell into the lake. Closely after that, they turned into 2 dragons and disappeared into the lake.
