Wei Cheng had only sequestered himself for a month when he was forced to emerge once again.
What use was it to continue in seclusion when all his resources had been exhausted once more?
Truth be told, Wei Cheng himself found it rather embarrassing.
Cultivation was simply too resource-intensive.
Just to make marginal progress in cultivating his Life Immortal Soldier, estimated at about 30% completion, he had already consumed Spiritual Energy materials worth about two hundred strands.
This came about indirectly through consuming a 5000 grade elixir.
It had taken him a total of eighteen days from start to finish.
It wasn't that he wanted to rush, but the potency of his Primordial Spirit World necessitated, other immortals, while cultivating their Life Immortal Soldiers, to ponder excessively over this segment for several hundreds, if not thousands, of years before they could generate a plan genuinely suitable for themselves.
