Lightning Is the Only Way

Gravis sat in his cave and consumed the first Bone-Pill. Compared to his time when he had tempered his skin, he didn't do any additional training while consuming the pills. There were multiple reasons for that.

First of all, back then, he had tried to cut the consumption of Skin-Pills by one pill, since he had seriously lacked money. The other reason was that it was quite hard to temper bones with training. Theoretically, he could punch and kick the cave walls to temper the bones in his limbs, but what about the ones in his torso and head?

Instead, he stayed in the cave and consumed one pill every few hours. He felt his bones slowly growing more durable, and every increase only fueled his hunger for power. This time was different from when he had tempered his skin.

Over the last three months, he had grown used to his isolation, and his new short-term goal was getting back to his family in his homeworld. If he came back to his homeworld, he would no longer feel isolated and alone.

He would have his father, his mother, Orpheus, and potentially other family members. Gravis may be alone in the lower world, but not in his homeworld. It might look dark and isolated here, but he only had to get through this, and everything would resolve itself. He only needed to break through the firmament of the lower world to return.

Greed and motivation drove Gravis to continue tempering his bones. Every increase in strength brought him closer to his goal.

Day turned to night, and night turned to day again. After a full 28 hours, Gravis had finished tempering his bones. He felt their vitality and their incredible hardness. He was sure that he would not be able to break his bones, no matter how hard he tried.

Bones were, by nature, harder than skin, and this also translated into tempered bones and tempered skin. Gravis' skin was incredibly challenging to break already, but his bones were multiple times harder. Over were the times, where he would have to deal with a broken shoulder in a fight.
