During the next few days, Lux was only present inside Khione's home, he didn't go out anywhere, neither did the others come and bother him.
Most likely, Khione told them that he was practicing a set of new techniques and he shouldn't be interrupted.
Those like Arthur and Faust were convinced that Lux had a 'great' time instead, and they decided to tease Khione a bit about it.
From that day on, Lux wasn't the only one who needed to recover completely...
'I'm close, I'm close to it...' Lux chanted inside his mind, but then, his left arm bulged uncontrollably and a fountain of blood erupted from his arm, "Fuck!" He couldn't help but curse out loud, attracting Khione's attention.
She quickly came over and saw the horrifying scene of Lux's arm almost exploding. "Lux! What happened?!"
She quickly came to his side but calmed down when she saw his serious expression.
