As the words fell, a golden halo began to envelop Song Yang's medium-grade sacred sword. This was the Law of Gold at 100%, which Song Yang understood due to his Sacred Domain of the Five Elements.

As for why Song Yang did not use the high-grade sacred sword he obtained after destroying the Celestial Sword Sect, or the Phoenix Blood Sword, an imperial-level artifact obtained from the legendary mysterious box:
The first reason is that it is unnecessary; after all, he is dealing only with an 8-star Saint.
Secondly, using the high-grade sacred sword would certainly reveal to the world that he has some connection with the Shura Palace, since it is no secret that it was the Shura Palace that destroyed the Celestial Sword Sect.
