"It takes over a thousand years just to hope for a breakthrough to the sixth-rank intermediate level, this speed is really slow!"
Gu Qingyang looked up at the sky and couldn't help but sigh.
Fortunately, he was already immortal; otherwise, how far he could go would have been an unknown.
After all, the higher the realm, the more evolution value required for a breakthrough.
From sixth-rank low-grade to sixth-rank intermediate-grade requires more than a thousand years, and by the seventh rank, it might take over ten thousand years, or even a hundred thousand years.
Even though Gu Qingyang originally had a long lifespan, he couldn't endure such a prolonged period.
Ultimately,
it's because the spiritual energy in the Cyan Yang Realm is too weak.
Compared to the Ancient Wilderness, the density of spiritual energy in the Cyan Yang Realm is shockingly low.
