Qingfeng Li knew of the strength of the Golden Light Sword from the beginning. He knew that the more sword techniques were acquired, the more magnificent the sword would become.
Even then, he was still surprised by the fact that he was able to put Wutian Mo on his heels just with the newly cultivated fourth sword skill. If only he could cultivate the fifth one, it would be guaranteed that he would be able to defeat Wutian Mo.
But the seals on the Golden Light Sword were extremely strong and firm, and only through leveling up his strength can Qingfeng Li be able to release them.
Qingfeng Li was in the fourth level of the Spirit King Realm and could only release the fourth layer seal – he was far from being able to release the fifth.
Even then, Qingfeng Li had made himself known by impressively sweeping and shaking up all that surrounded him with his power.
