Zhonghai City, Longyang County.

As the top three top-tier cities in China and a well-known international metropolis, Zhonghai City is located at the sea's estuary, backed by the vast inland, facing the sea, where countless trade ships gather here, making it a top city in the world.

Therefore, in the county under the jurisdiction of Zhonghai City, everyone sharpened their heads and squeezed into Zhonghai City.

People who stay in Longyang County are all crooked melons and jujubes, and they belong to the category of people who eat and wait to die.

On February 15th, Zhicai School, mock exam.

"Student Li Yun, wake up!"

The invigilator, who is also the physics teacher of Class 14, knocked on the table of a boy who was sleeping on the table with a helpless expression.

The next semester of the school just started. The school organized a mock school exam; the purpose is to let students enter the state of preparation for the college entrance examination as soon as possible.

Of course, the purpose of this mock exam is not for the students of Class 14. Class 14 is lower class. It belongs to a group of hopeless students. The school has long given up and only asks them to pass the exam and obtain a diploma. Just don't make any trouble.

But this boy named Li Yun was too presumptuous and went to sleep on his stomach during the exam.

Physics teachers can ignore those who crane their necks and want to peek at other people's answers because this classroom is full of poor students, and they can't copy them if they want to.

But if the inspected leader sees a sleeping examinee, his invigilator will inevitably be glared at by the leader.

"Student Li Yun!!!"

Pushed by the teacher, Li Yun finally woke up, rubbed his eyes and yawned.

The physics teacher's eyelids twitched furiously. This student is not bad in appearance. He is 1.78 meters tall, has good facial features and a well-proportioned body. It belongs to the level that girls will look more at when walking on the road.

But it was his lazy appearance that destroyed his sunny and handsome temperament!

"teacher."

Li Yun nodded at him, motioning to wake up.

The teacher snorted and said, 'do your test,' and then continued to patrol with his hands on his back.

He doesn't ask Li Yun to get a passing score, which is impossible for the lower class students. They will have at most two or three multiple-choice questions, and a double-digit score is considered a high reputation!

Li Yun also knew what the physics teacher meant, but he had no other choice.

Li Yun grew up in an orphanage, and when he was six years old, he was taken in by a kind old man.

Also taken in with him, there is another person whom Li Yun attaches great importance to, and also his god-sister, Li Feng.

The old man passed away a few years ago, leaving Li Yun and Li Feng, as well as the old man's two granddaughters. A family of four was facing distressing economic problems. Li Yun had to carry the family and chose to give it to others at night. Work part-time to earn living expenses and tuition.

Therefore, Li Yun has nothing to do with this indefinite physics multiple-choice question in the test paper.

"Three shorts and one short election are the shortest, and three shorts and one long election are the longest." Li Yun said silently, "It's you, choose D!"

"Ding! Congratulations to the host for obtaining the God-level selection system. The system is initializing...1%...100%, and the binding is successful!"

What? System?

He picked a D and got a system?

Li Yun frowned, wondering if he had a hallucination.

Nothing happened; next, Li Yun gave a wry smile; there is no system in the novel in the world.

He should continue to do the problem.

"As shown in Figure a, a lightweight spring...A: When the object is separated from the spring...B: The spring stiffness coefficient is 7.5Ncm..."

Seeing this indefinite physics problem with an exploding difficulty, Li Yun frowned.

The so-called indefinite multiple-choice questions are that there are multiple correct answers in the answer. All the correct answers get 6 points, the right but incomplete choices get 3 points, and the wrong choices earn 0 points.

Therefore, multiple-choice questions in physics are the most difficult in theory.

At this time

"Ding, triggered an option, please choose the host:

Option 1: Write nothing, no reward.

Option 2: Write the correct answers A and B on the test paper, and reward novices with a big gift package*2! "

"Huh... ? there is a system?"
