"Golden Bones": Gu Yanzhi was born with gold patterns on his bones, but he was judged to be "waste bones". While forging iron, he discovered that gold patterns could strengthen weapons. During a certain casting, the golden patterns on his fingertips were integrated into the sword, and the sword actually gave birth to spiritual intelligence. When the sect's magic weapon was robbed, he pulled out the sword, and the sword let out a dragon's roar, scaring the enemy into fleeing.
