บท 98: The Regenerative Serum.

"Oh? What do you have in mind?" Heinrich asked; he was curious what this young man had in mind.

"I have a serum that can regenerate hands and legs in the human body," Jack said, smiling as Heinrich's face looked at him as if he was seeing a fool.

"Are you an idiot or making me one?" Heinrich said he was not believing in Jack.

"I've got one; trust me, I'll make one if you're not believing me." Jack said he was actually casual about it because he knows how to make it, but he'll only give out the legs and hand regenerative one because he wants to make this product in his company.

"Alright, I have a buyer for this if you're willing to sell such an item," Heinrich smiled and said, because he was astonished when Jack pulled out 4 billion € like it was nothing.
