He acted as soon as the thought came to him.
The moment a divine inscription appeared within the sword, he suddenly felt unbearably weak.
Even after going three days and three nights without sleep, he would not have been this weak.
His body instantly became as heavy as a mountain. Even breathing felt laborious, and his vision swam in waves.
Fortunately, the Golden Sword showed no change, remaining both light and weighty.
The next moment, gurgling springs poured into his mind, and his vision abruptly cleared.
His mountain-heavy body became light as a feather again. His breathing was faint yet flowed into his organs; every breath purged the turbid air from his body, leaving him refreshed and brimming with strength.
This was Spiritual Power from Chu Liezhao and Leng Tieya, lending him a helping hand.
He continued with the second divine inscription.
A slight heaviness had already settled in his heart, and he vaguely sensed that something was wrong.
Leng Tieya had already assumed the stance of the Nine Heavenly Demon Arts, beginning to draw upon the power of the void and transform it into Spiritual Power.
When the second divine inscription was fully engraved, he swayed on the verge of collapse, nearly unable to remain standing.
The gurgling springs in his mind could no longer dispel the waves of weakness surging through him.
He understood that this was his limit.
So he stopped without hesitation.
He lowered his head to look at the Golden Sword.
After gaining these two divine inscriptions, it had already changed.
The two characters were "She" and "Ji," precisely the two divine inscriptions of the Emperor's Sword.
With these two divine inscriptions, it was in truth no different from the Emperor's Sword.
He focused and pondered what differed between this sword and the Emperor's Sword.
