Time flew by.
Void Dragon Vine's strength rose far faster than Song Wen had anticipated.
In less than two years, its bottleneck at the late ninth tier crumbled with a thunderous crash like a dike battered by a raging flood.
Void Dragon Vine's strength surged in an instant, advancing to the peak of the ninth tier.
If it had been a human cultivator or a Demon Race creature, breaking through this bottleneck would surely have drawn down a heavenly tribulation.
Yet Void Dragon Vine's breakthrough caused little commotion.
Perhaps because Void Dragon Vine had advanced by absorbing and refining the Primordial Chaos Qi Embryo, the surrounding origin qi showed no widespread abnormal fluctuations. Only the origin qi within a hundred miles gathered toward it.
As a result, only a few low-tier Void Demons and resentful spirits noticed the anomaly and came to investigate, only to be dealt with by Song Wen without a sound.
Void Dragon Vine had still not exhausted all the energy within the Primordial Chaos Qi Embryo. It continued refining it, pressing onward in one great push toward the Immortal Realm.
Three months after Void Dragon Vine advanced, Shadow Void also underwent a change.
Its fluctuating aura suddenly stabilized, reaching the consummate state of the late ninth tier.
Then, Shadow Void abruptly awoke, its long, narrow eyes snapping open like lightning.
It too began absorbing the origin qi of heaven and earth to aid its attempt to break through the bottleneck.
Another ten years passed in the blink of an eye.
This day.
The origin qi in the underground cavern suddenly churned violently like boiling water.
"Master."
Void Dragon Vine's voice rang out, clear as silver bells.
"I am about to advance to the Immortal Realm. I fear the commotion will not be small."
