As Rein invested 8 Golden Skill Points in the First Level Witchcraft 'Metal Barrier' at once, the witchcraft 'Metal Barrier' instantly rose from lv12 to lv20!
In a flash, a vast memory regarding the witchcraft 'Metal Barrier' surged into Rein's mind.
For a moment, Rein seemed to arrive in a mysterious space, practicing the witchcraft 'Metal Barrier' for over a hundred years, with the chanting of spells becoming almost instinctual, and the syllables compressed with increasing speed.
In the end, Rein merely had to move his lips for the casting to be completed.
After Rein digested the memory, he found the casting time for the First Level Metal Series Witchcraft 'Metal Barrier' was reduced from around 0.25 seconds to about 0.04 seconds.
This reached a level even an Official Knight couldn't react to!
This couldn't help but make Rein exceptionally satisfied.
Using the same steps, Rein applied them to the witchcraft 'Sharpness Technique', with 4 Golden Skill Points invested.
