As expected, demonic crystals were the currency in Hell. It could basically be used for all types of trades.
"How much money can I get with these demonic crystals?" Chen Zhao cared more about the exchange rate.
"There's no set amount."
"What do you mean?"
"I can help you discover ways to make a fortune around you. The more you put in, the bigger the possibility to get rich."
"Possibility? So it's not definite?" Chen Zhao lost his temper. "After all this time, you're just playing with me? Leave. Go back to Hell. I don't need you two."
"No." White Mammon immediately bit Chen Zhao's clothes. "We haven't succeeded yet. We haven't even tasted a demonic crystal before. Don't chase us away."
"What do you mean you haven't succeeded yet?"
White Mammon was already crying pitifully and wretchedly. Black Mammon was curled on the ground, not making a sound.
