Breakthrough from Iron to Bronze

[Do you want to initiate the breakthrough from iron to bronze?]

[Y/N]

'Heh… sure I guess,' he didn't see any reason not to do that as he had already finished his training for now, and had acquired the reward for his quest.

He clicked on the Y option, and suddenly…

[Very well, please break the stone now!]

"Alright," he shrugged, then clenched the fist with the stone inside of it, putting more and more pressure until eventually…

~BAM~

It shattered inside his hand.

The runes around the [Breakthrough Stone] were glowing, and as soon as he broke it, they immediately began to fly around Stark.

For a moment, he was surrounded by small glowing motes of power, dancing around him in an intricate ballet.

They began to slowly but surely disintegrate as they sipped inside of Stark's body.

And after only a few seconds… the stone and its runes had completely disappeared.
