In the blink of an eye, half a month passed.
Half a month of secluded cultivation allowed Li Yun's cultivation to reach the 7th level of Earthly Core Realm. He had already been at the very peak of the 4th level of Earthly Core Realm, and the resources he had obtained from the underground palace allowed him to rapidly climb three small levels in one stretch.
With his current strength, he could already swing the Grand Profound Five Elements Sword twice in succession. His Soul Sword Control Art had also improved to the point where he could simultaneously control nine hundred precious swords.
However, after reaching nine hundred precious swords, Soul Sword Control Art also reached a difficult threshold. From this point onward, even controlling one more precious sword would cause the difficulty to increase exponentially.
