Breakthrough.
After returning to his room, Felix didn't waste any time and sat on the floor near the window, his body still in the battle state as before.
'Let's do this!'
He unhurriedly took out the advancement potion Mr.Dealer had given to him and kept it to the side.
Releasing a deep breath, he closed his eyes, focused his mind and circulated the energy inside his body to move around through his nerves.
Slowly but surely, his consciousness reached the peak of concentration as he could feel his blood crazily pumping out from his heart and travelling to the other parts of his body.
The rythmic breaths of the meditation technique controlled the blood path and all the nutrients it had, sending it to his internal organs and strengthening them.
This process took a whole hour, after which he felt his blood slowing down and not producing anymore nutrients, but all he needed was one last push.
