At his current rate of growth, by then, he would at least be an Immortal-grade Heavenly Sovereign.
Perhaps he might even have entered the ranks of Saint-grade Heavenly Sovereigns.
How strong he would be by then was likely impossible to say.
With his strength alone, perhaps even sweeping away the entire Evil Race from Beyond the Domain would not be difficult.
Even if he could not wipe out the Evil Race from Beyond the Domain, he would never fear any encirclement.
With that level of strength, even without the Shatian Demon Emperor provoking him, he would still make a trip to the Evil Race from Beyond the Domain's territory.
For no other reason than to exterminate demons.
The Evil Race from Beyond the Domain was something he would eradicate in this lifetime.
And the Shatian Demon Emperor's head was also his for the taking.
Yet the Shatian Demon Emperor did not know Lu Yunxiao's thoughts. In its eyes, three years was merely the time it took to take a nap.
No matter how talented Lu Yunxiao was, it did not believe he could achieve much of a breakthrough in three years.
Which Immortal-grade or Saint-grade Heavenly Sovereign had not spent centuries, or even millennia, cultivating?
Once one reached the Heavenly Sovereign realm, breakthroughs were no simple matter.
What it did not know was that its logic only applied to ordinary people.
And Lu Yunxiao was no ordinary person. He was a cheat.
And cheats were the most unpredictable, scientifically inexplicable creatures.
"Hehe, then this Emperor shall await the day of your arrival. Do not get scared halfway through and fail to come."
The Shatian Demon Emperor sneered mockingly.
"Heh, you should worry about yourself instead."
"You have three years left to live at most."
Lu Yunxiao gave a cold laugh
