Over the next ten-odd years, Xu Changxing went into seclusion again.
Only after thoroughly stabilizing his cultivation at the heavenly immortal sixth stage did he emerge again.
He had barely stepped into the courtyard when he sensed a faint fluctuation of killing intent.
Xu Changxing paused, then realized that this fluctuation should have come from the Seven Killing Intent Eyes below.
Could the people of Hundred Calamities Valley have made their move so soon?
In the previous simulation, Hundred Calamities Valley had only detonated the seals surrounding the Killing Intent Eyes after a hundred years.
Since there had still been plenty of time, Xu Changxing had not been in a hurry to warn Bu Yufeng.
Yet now, barely more than ten years had passed, and he could already faintly sense unusual activity within the Killing Intent Eyes.
Hundred Calamities Valley is moving a little faster than expected...
Xu Changxing's original plan had been to expose Hundred Calamities Valley's scheme.
However, his cultivation had advanced far faster than expected, so he had no fear of an attack from Hundred Calamities Valley.
Moreover, if he could kill a heavenly demon while Hundred Calamities Valley initially underestimated him, future battles against them would be much easier.
At this thought, Xu Changxing did not go to see Bu Yufeng. Instead, as though he knew nothing of the matter, he returned to seclusion and continued condensing Upper-Grade Immortal Essence Stones.
After he reached the heavenly immortal sixth stage, the number of Upper-Grade Immortal Essence Stones needed to begin another simulation had soared to thirty-two.
However, as his cultivation rose, the speed at which he condensed Upper-Grade Immortal Essence Stones also increased.
For the next year or so, Xu Changxing did not cultivate, instead devoting all his efforts to condensing Upper-Grade Immortal Essence Stones.
