The skill of furnace tempering, as an advanced skill, is also particularly difficult to cultivate.
Merely advancing from the master level to the expert level requires the consumption of 81 "Skill Cultivation Cards". when breaking through a bottleneck, it even requires the aid of "1 Purple-Tier Cultivation Card".
Not only that, but this skill is more painful to practice than ordinary skills and consumes a great deal of mental energy, so Fang You dared not push himself too hard at once.
Ten attempts at a time was about right.
To do more was not impossible, but he needed to ensure that he maintained a certain level of combat power.
He had to go out for trade negotiations, light up the Dawn Lighthouse, check on Citina's situation, and so on and so forth. There were many matters that needed to be dealt with. Therefore, it took him ten days to cultivate the skill of furnace tempering to the expert level.
"A full ten days."
"This really is... too strenuous!"
Teacher Fang sighed.
