I Get Experience for This?

As Ge Liang went to cook some eggs, his sister popped out from her room. She was also in his dorm, and they attended the same college. However, annoyingly, he was born 10 months earlier, and as a result his parents had always expected him to be the kind, doting, amazing older brother. What a joke, Ge Liang thought. She's always using it to leech off of me! Just as Ge Liang was thinking this, his sister, Ruo Xiangyi spoke up. "Big Brooooo, cook me some scrambled eggs! I'm too tired to get up todayyyyy...." Goddamn! That sister of his... Already in college and still so lazy! With a resigned sigh, Ge Liang went to go cook the scrambled eggs. He was feeling pretty hungry himself. As he was preparing the eggs, a system notification sounded.

*Host, a new quest has been issued!*

Finally! I, Ge Liang, at last get to accept quests! He looked tentatively to see what it was.

Ge Liang: .....

Quest: Cook eggs for your sister, Ruo Xiangyi.

Cooking EXP gain: 5

Ruo Xiangyi Influence Points: 5

Shit! Of course the system gave him a crappy quest like that.... He whisked up the eggs and put them in the pan. They gave off a nice smell and they looked to be tasty. At the end of his cooking, he prepared a glass of orange juice for Ruo Xiangyi and headed up to her bedroom with the food. Happy sounds were coming from her as she ate the eggs.

*System Notification*

Quest Rating: A-

*Quest Message: Decent eggs for a beginner, and added some extra orange juice too! This deserves an A-.*

*Quest Rewards: 5 + 2 bonus Cooking EXP, 5 Influence Points with Ruo Xiangyi, a blueberry muffin*

*The Ultimate Economic system rewards you for your work! Host, continue accepting quests for more rewards!*

Ge Liang looked at his rewards and smiled. He had no idea what Cooking EXP or Influence Points were, but he sure as hell liked a good blueberry muffin! Just to be sure he knew what he was getting, he asked the system for clarification.

*Cooking EXP is a measure of how good you are at Cooking! There will be more and more skillsets coming up for you to master!*

*Influence Points are a measure of what your bonds are like with a certain person. They are boundless, but the law of diminishing returns applies.*

Ge Liang thanked the system, and began to ponder. It was named the Ultimate Economic System, which clearly meant he could make lots of money! So how was he to do this?
