The day Shang Qingya's spiritual root was deposed, everyone said he was finished.
After two years of cleaning the sword at the pool, he polished the iron sword for seven hundred and thirty days. The blade was curled, but the man was not.
When he came down from the mountain, his master gave him a saying: "Don't forget the mulberry trees at night, the sky will still be covered with clouds."
No one knew that when the black stone swallowed up his spiritual power, it also swallowed up something else.
When the curled iron sword was unsheathed again - this time, he no longer needed spiritual power.
