In the following days, Xu Ping'an spent nearly all his time in seclusion within his small courtyard.
He first consumed all the elixirs on his person, ultimately completing only three hundred strands of True Yuan transformation.
However, when he consumed the Fifth Rank monster cores, the efficiency greatly increased.
A single monster core could roughly complete ten strands of True Yuan transformation, and although the effect was gradually diminishing, it was significantly better than the elixirs for Xu Ping'an.
Over five days, Xu Ping'an consumed a total of one hundred monster cores.
Eventually, he completed seven hundred strands of the True Elemental Transformation.
Adding the previous three hundred strands, Xu Ping'an had accomplished a thousand strands of True Yuan transformation.
A thousand strands, that was one-fifth completed.
The efficiency was already quite high.
Now, the power Xu Ping'an could unleash was double what it had been before.
