A young man, Chen Ping'an, walked three thousand miles alone with a rusty iron sword on his back. Everyone laughed at him for being shabby and crazy, for actually trying to kill immortals and demons with ordinary iron.

Only the inconspicuous iron sword buzzed out of its sheath, and a ray of sword light stretched across 30,000 miles, making the stars and rivers tremble. After the smoke and dust cleared, the young man wiped his sword and asked softly: "Do you think I can kill an immortal today?"
