Being Successful with the System
episode 16

After serving a group of uninvited guests, the food stall was closed, and Rio finally had time to answer the test questions given by the slamet.

Just before going upstairs, she advised her parents to add the [Supreme Beef Noodle] dish to her food stall menu.

This dish is a natural beef noodle made by Ruo.

It also stipulates that the noodles are only sold on weekends.

In this way, He can avoid coming into contact with the Dragon, and make this dish rare and expensive, and increase its value by making it a mysterious dish.

The most important thing was that Rio could get a lot of rest time.

He doesn't want to be a chef after school every day.

late night.

Deni and Melinda who saw Rio studying seriously, they could not help but smile at each other.

The series of changes that had recently happened to their son had completely shocked the two.

It was like a child growing up overnight.

At this moment, Rio was sitting in front of the table, and in front of him was a paper with the title of the matter of function.

"System, help me solve all these problems."

"Ding! The answer has been sent to the brain of the host, please check."

As soon as those words came out, there suddenly came a lot of knowledge about trigonometric functions in his mind.

"Sin²A + cos²A \= 1 ......"

"TanA \= sinAcosA ..."

"..."

Rik lifted the pen, and according to the knowledge in his mind, he wrote the steps of solving the questions that were on the problem paper.

"OK, done, So~ Easy!"

after feeling very satisfied with the ability of his system, Rio turned off the lights to sleep.

......................

No one was concentrating on the class, and his attention was only on the two boys in this class.

That slacker son/bedler is the Rio, and the handsome delinquent is Devin.

"the time has come, who among you will give me the first answer?"

The eyes of the slamet sir narrowed, looking at rio and Devin.

Everyone's eyes were also staring at the two of them.

"Sir Slamet, let me answer you first."

Devin glanced at Rio with a mocking smile and walked towards the blackboard.

This handsome appearance of his made many girls in the class emit small stars in their eyes.

Cindy suddenly looked at rio nervously, but found that rio still looked sleepy.

Her extremely indifferent appearance like this made Cindy become anxious.

" is brother rio going to make it?"

one thing he did not know that at this moment, Rio was constantly complaining: "the shameless old wife's husband, making people unable to sleep every night!"

the slamet sir took the paper from Devun's hand and held her glasses meticulously.

mr. Slamet nodded in satisfaction: "The steps are clear Although the method of solving the problem is a little conservative, there is no mistake. Pass."

Devin proudly raised the corner of his mouth and returned to his seat, looking at Rio with a look of disdain.

"Victory and defeat are all we know, and Devin can go to the competition."

"You can go to a regional math competition in your first year of high school, it's a feat to be proud of!"

Mr. Slamet looked at Rio and said lightly: "Rio now it's your turn."

Rio rubbed his tired eyes and accidentally took out a stack of papers from the school bag.

When he handed a stack of papers into the hands of Mr. Slamet, all of his classmates except Cindy insulted him.

Mr. Slamet was also cold-eyed, pointing at the thick pile of paper, coldly saying: "Rio, what does this mean?"
