Young Jun Wuyou has been carrying the Soul Locking Seal of the Red Sun since he was a child. Every full moon, it burns bones and scorches the soul. After sixteen years of hard training in the extreme cold, he successfully awakened the dual elements of ice and shadow. From then on, carrying his unknown life experience and his parents' last wishes, he stepped into the Xuantian mortal world where martial arts were respected and strange demons were rampant.
From the boy with silver bones to the twin emperors of ice and shadow. From a baby carrying a poisonous seal to the legend of pacifying the Thirteen States and saving the mortal world. Jun Wuyou will eventually cut down the sky with his sword, prove his heart with the Tao, and become an unparalleled king when the mortal world is overturned.
