Manablood

The villa that felt foreign to him at one time became a rather familiar place. Over the past few weeks, Arthur came here a dozen of times whenever he had the chance to. Master Ronin was the ex-principal of Jerano College, making him one of the best people that could teach Arthur about mana.

Their first lesson started before Arthur went into the trial, and they have resumed them after he was back. It was mostly about mana control, how to increase his mana, and how to replenish it through breathing.

Breathing was the path to immortality.

That phrase was often used by Master Ronin. Arthur didn't know about immortality, but if breathing would make him stronger, then breathing he would do. It seems this process accelerate the infiltration of mana to the body.
