"Heh, good, you've got courage," Concubine Yu sneered. "You won't get short-changed on the rewards, but can you really obey me?"
"Don't worry, if the rewards are enough, I'm more obedient than anyone else," Jacob replied with a faint smile.
"What do you want then?" Concubine Yu stared at Jacob, as if trying to read his thoughts.
"I demand a Dragon Elixir." Jacob's words turned Concubine Yu's countenance grim.
"Dragon Elixir, are you aware that it is the inner alchemy of the Dragon King, only to be acquired after thirty years of cultivation? Every Dragon King's Dragon Elixir is treasured as a jewel. You've just blurted out about wanting a Dragon Elixir, quite lofty there," raged Concubine Yu.
"I apologize, but I don't care for its rarity," Jacob shook his head and stated. "Honestly, I only care for what I want. I’m a doctor. The Dragon Elixir has what I need."
"If I have a Dragon Elixir, perhaps I can unravel something which can shock the world," he mused out loud.
