According to the time it took Li Shiqing to break through to Golden Core, Li Zhirui would need at least five years for this seclusion, or even longer.
After all, Li Shiqing had refined himself for an unknown period of time at the later stages of Foundation Establishment, his foundation already incredibly solid, incomparable to the current Li Zhirui.
Li Zhirui was aware of this, so the duration of this seclusion he set for himself was at least five years. Up to ten years wasn't out of the question either, and he was fully prepared for a 'long-term battle.'
As Li Zhirui once again entered the quiet room to seclude himself, Li Shiting and the others sent by the family quietly arrived at Green Mountain State.
They brought with them a large amount of Spirit Stones, changed their identities several times, and after running around several auction houses, they finally acquired eight Foundation Establishment Pills.
