Mediocre is a common characteristic of the majority. But when someone outstanding appears beside you, your life will change because of him.

Gu Zuo: Are you sick?

Gongyi Tianheng: You have medicine?

Simply speaking, a scaredy-cat shou transmigrated and had to think of a way to survive. He had a golden finger called Medicine Refining System, but unfortunately, he didn’t have the ingredients needed to refine medicine and level up.

A great young master to an empire’s preeminent clan had a super high IQ, but his potential for cultivation was low. Unfortunately, pill refiners were too hard to develop, and weren’t restricted to his personal service. But he could acquire plenty of ingredients.

Two people, one was sick and one had medicine. Therefore, the one who was sick kept the one who had medicine, and everyone was happy.
