Liam was visibly shocked.
A Rank 5 tempering method?
Even if it was a base, non-elemental technique, Liam couldn't imagine how strong his body would be at that level.
Not to mention, it would solve his problem of finding another tempering method after advancing to the fourth Rank, and the general scarcity of techniques at that level.
Although his inscription abilities had improved by leaps and bounds, he didn't see himself inventing Rank 3 techniques, let alone Zenith Ranked tempering methods.
It was the same with the Rank 4 cultivation technique. He was already set for the third Rank, but eventually, he'd have to start looking for another.
'There's still a lot of time left before I have to look ahead.'
Then there was the spell that would strengthen each time Liam's sea of consciousness advanced.
It was obvious what he was going to choose.
