"This is the Gold of Vitality."
Cao Jingjing explained, "It's a unique metal from another world that can grant someone immense recovery abilities."
Jos exclaimed in surprise, "Similar to Wolverine in X-Men?"
"An apt comparison," Cao Jingjing nodded. "However, it's slightly weaker, and you have to cut open your own heart to implant it."
Hiss——
The group all gasped in shock.
This was about cutting open one's heart!
Even vampire hearts did not need this; it was sufficient just to cut the skin and absorb it with the flow of blood, but this Gold of Vitality truly required cutting open the heart.
Ordinary people wouldn't dare to try it.
After all, there were not many in the world who dared to embed a piece of Gold of Vitality in their heart for an unverified ability.
Even though Cao Jingjing would never lie, still—
Seeing is believing.
