After the clone of his grandfather disappeared, Silver looked at the glass vial his grandfather gave him. The vial contained a blood red liquid in it.
Silver observed it for a few seconds, then he opened the vial and drank the blood red liquid in one go.

Silver threw the vial away, and he grabbed his left arm. He could feel an itching and burning throughout his left arm.
Knowing what he had to do, he gritted his teeth and twisted his left arm to its natural position. He groaned as he felt extremely uncomfortable due to the pain his left arm was going through.
Unfortunately, the potion his grandfather had given him was meant to temporarily speed up his regenerative abilities to a high level. It did not have to ability to magically heal his broken arm and fractured arm immediately.
