In the earlier days, the legendary demon spirit master, Saint Mu, practiced a technique of the thunder element.
By transforming his own body into that of thunder, he managed to tame the Heavenly Falling Divine Thunder Sword.
This method was undeniably effective, but it had severe side effects, causing irreversible damage to Saint Mu's Soul Realm.
Thus, he passed away at the young age of thirty-nine.
Typically, thirty-nine years old is the peak age for demon spirit masters, making Saint Mu's untimely death a cause for deep regret.
Afterward, no one was able to tame the Heavenly Falling Divine Thunder Sword.
To prevent its murderous aura from leaking out, the legendary demon spirit masters constructed the Heavenly Illusion Sacred Realm to seal the sword within.
Unlike Saint Mu, Nie Li chose not to modify his own body to tame the Heavenly Falling Divine Thunder Sword.
Instead, he converted the power of the demon spirits within the sword for his own use, using that power to suppress the sword itself!
Nie Li was taking a risk; although he only possessed Silver-level strength, he achieved what even legendary demon spirit masters could not.
“If we had known this method could suppress the Heavenly Falling Divine Thunder Sword, we could have wielded that divine sword back then!” sighed Ancestor Ye Yan.
