The four from Kao Mountain found themselves in an awkward situation. Their power indeed suppressed the Jade Solitary Sword, but merely relying on the mountain's power was not enough to completely suppress the sword. They needed to use their own Primordial Energy as an aid to fully suppress the sword, preventing it from having any chance of escape.
They tried several times, but once the mountain lost their support of Primordial Energy, the mountain would start to tremble, and the sword's singing would gradually grow louder, as if it might break out from beneath the mountain at any moment.
However, their Primordial Energy was not inexhaustible; sooner or later, it would run out at this rate.
The four from Kao Mountain secretly lamented. Even if their Primordial Energy could always last, they couldn't just do nothing and guard this mountain their whole lives responsible for suppressing this sword.
