The technique book
Lucas made a batch of rejuvenation potion, a batch of normal-grade mana potion, and some dirty water from the nails just for increasing the skill's proficiency.
Lucas then went to Sean's small workshop, there were many rocks on the ground with scribbles inscribed everywhere. Lucas let him be as he was in too much concentration, Sean didn't even realize that Lucas was there with him.
'I should go and spar with Jerry first.'
Lucas thought and took his sword out before moving, his left eye was still not working but he had grown a bit accustomed to it.
The walks, jogs, and sprints had helped Lucas in growing accustomed to the blindness.
His distance ratio had also perfected to some extent and he felt even keener to his surroundings and dangers now that he could not look at one side of his whole vision.
Like always, Jerry agreed to sparring with Lucas but today was a bit different.
