However, Zhou Sui could not afford to wait for several years.
After all, the current situation is so dangerous, who knows when the Ghost Demon Sect will break through the defense formation of Misty Cloud City.
If they succeed, it would be far too dangerous considering his current level of cultivation.
Even if he could hide in an underground shelter, who knew what could happen unexpectedly.
What if some disaster cultivator, or a Foundation Establishment cultivator, discovered the underground shelter he built himself.
This is not an impossibility.
Only great strength can handle any sudden or dangerous situation.
Therefore, he could not afford the time to spend several years breaking through the bottleneck of the Late Qi Cultivation. If he could, he would like to break through now to improve his strength as quickly as possible.
Luckily, he had been prepared for a while.
Several months ago, Zhou Sui had obtained a Breakthrough Pill from those cultivators of the Ghost Demon Sect.
