Shen Luo discovered that there were actually sixty-four restrictions on the ancient mirror, it was among the top existences in magical treasures, and his heart couldn't help but leap with joy.
He immediately started running the Innate Treasure-refining Technique to begin refining the Free and Easy Mirror.
However, to his surprise, even with the mighty power of the Innate Treasure-refining Technique, refining the Free and Easy Mirror did not proceed in one vigorous effort, and he couldn't break all the restrictions at once.
Shen Luo spent quite some time before he managed to break through eight of the restrictions.
The rest of the restrictions weren't impossible to break, but it would just take more time to grind through, which he didn't have at the moment, thus he had to give up.
Nevertheless, just by opening eight of the restrictions, his divine sense was already able to enter the Free and Easy Mirror for a peek.
