"Qing Feng Yin": Su Qingci was born with double sword bones, but was mistakenly diagnosed as having "miscellaneous spiritual roots" and was expelled from the sword sect. He picked up half a rusty sword in a barren mountain. The sound of the sword awakened the sword veins in his body, and the sword energy split the clouds while practicing the sword. When the sect that had abandoned him was attacked, he came in white with a sword, and cut off the Nascent Soul monk's magic weapon with one sword, and the rusty sword suddenly glowed with green light.
