In times of chaos and calamity, a solitary swordsmith known as "Single-Blade Man" would emerge, offering a suitable sword to those destined to receive it. He asks for no payment, leaving only a few prophetic words behind. When the prophecies come true, he returns to collect the "blade fee." Born in humble circumstances, Shu Yu obtained a renowned sword named "Mu Zheng" from the swordsmith Tang Dao. He learned his destiny from the prophecies and gained extraordinary powers. With this, his fate underwent a tremendous transformation.
