When his spell levels reached [Lv51],
the cost in mid-grade magic stones jumped to [10000], with an additional cost of [1] superior magic stone.
Though that expenditure posed a challenge,
for An Kai, who controlled Goodness Home,
the difficulty was limited.
Over two years, through some adjustments and some enticements,
An Kai had successfully obtained enough resources to max out all his spell levels.
He even had plenty left over.
For example, he currently had nearly six figures' worth of [mid-grade skill points], exchanged from mid-grade magic stones or mid-grade energy stones.
He also had [16] superior magic stones remaining.
An Kai had assumed that this major advancement would increase the resource requirements, but surely not beyond his expectations...
Yet An Kai discovered he had been wrong.
He had underestimated the resources required for every increase in his spell levels!
To raise a spell from [Lv60] to [Lv61], An Kai needed [superior skill points*1000]+[top-grade energy stone*1]!!!
[1 superior skill point] = 1 superior magic stone/1 superior energy stone!
[1 superior magic stone] = [10000 mid-grade skill points]!
When An Kai learned this conversion rate from the system,
he felt a hint of despair for the first time...
He had practically scoured every force on the continent, spending two years gathering lower-grade magic stones and mid-grade magic stones from them.
Even with the superior magic stones included, everything combined was still insufficient for [1000 superior skill points]!
And that was only one of the requirements.
A requirement An Kai could fulfill by accumulating resources over a long period.
Though it felt somewhat hopeless, there was at least a chance of completing it.
Yet the requirement of [top-grade magic stone*1]
struck An Kai's skull like a sledgehammer.
An Kai had absolutely no idea where to find [top-grade energy stones]!
Through [Contract], he
