Xie Dingyuan looked at the system message "the other party has passed your friend's verification. Now you can start chatting", and his heart beat.

Xie: [hello.]

The man frowned when the head didn't respond.

Xie: [you know r = a (1-sin θ) Are you ready?]

Still no response.

Xie: [then r = a * cos (k θ)? Also known as the rose line formula.]

Xie Dingyuan took a deep breath and waited quietly.

About half a minute later——

Month: [f * k!]

Xie Dingyuan: "

Month: [did you install a Trojan horse in my computer?]

The man was stunned. He had already cleared it. How could he

Month: [although it's only one minute, you can't fool my defense system!]

It turned out that it left a trace.

Xie: [I can explain.]

Month: [explain a fart! You wretched uncle!]

Obscene, obscene?

Uncle?!

Xie Dingyuan's face turned black.

Ready to explain, the beaded gun——

Month: [I also invaded your computer with a virus. It's even, otherwise I'll definitely want you to look good!]

Month: [don't think you can flirt with your sister casually if you know some math knowledge.]

Month: [you were still wearing open crotch pants when I played Cartesian function!]

Xie Dingyuan's eyes were confused.

When he reacts, he has been deleted as a friend by the other party.

Just, very suddenly

Jiang Fuyue strengthened the defense system again before turning off the computer.

Fan Ye happens to come in with her mobile phone and headphones. She should be talking to people about video.

Jiang Fuyue compared her to go to the bathroom and motioned to go in and brush her teeth.

Fan Ye replied with an "OK" gesture.

Jiang Fuyue tried to avoid the camera and leaned into the bathroom.

"Dad, I went back to my room."

A low voice came from the other end, precipitating the vicissitudes of the years: "is there anyone else?"

"Hmm! My roommate! Sister Yue! I mentioned it to you before."

On the screen, the man with a moustache gave a slight meal, "... Then you should rest early. In the future, don't make video calls with any opposite sex in the dormitory, including me, so as not to disturb others."

Fan Ye sticks out his tongue, "I know, but I don't think sister Yue will mind..."

"Do your part."

"I see, Dad. It won't be like this next time."

"Yes."

……

On the third day of the competition, the examination officially began.

Five hours, three questions, test run halfway.

Forty minutes after the test, Jiang Fuyue completed all the tests and the test run was successful. Click to hand in the test paper,

Then, leave the examination room.

Fan ye came out the second and looked at her relaxed eyebrows and eyes. She wanted to finish it well.

"Sister Yue, there is a small cake there. It looks good to eat. Shall we go there?"

"OK."

They waited in the rest area for about 50 minutes. Huang Hui and Gao Zhaoming came out one after another.

At two o'clock in the afternoon, the exam is over.

The ranking is immediately displayed on the electronic screen——

Jiang Fuyue and Fan Ye both got full marks of 300, tied for the first place.

Huang Hui and Gao Zhaoming followed, one 298 and one 295, ranking third and fourth.

When the four came down to communicate, they all had the same feeling: the topic was not difficult, or even simple.

But the results of contestants from other countries do not seem to be ideal.

For example, the player from country h, who ranked fifth, scored 265, and 295, a full difference of 30 points.

Jiang Fuyue: "it's too early to evaluate the difficulty."

Huang Hui nodded: "yes, there are three more questions tomorrow."

Gao Zhaoming scratched his head: "it seems that the news that some Chinese experts have a problem is false."

Fan Ye blinked: "not necessarily! Maybe tomorrow?"

"It's hard. In previous years, only the first three questions were invited from Huaxia, and the qualification of the last three questions has never been given to Huaxia. So..." Huang Hui stood up.

"OK." Fan Ye said regretfully, "it's almost time. Let's go to dinner?"

Jiang Fuyue got up and said, "go, I have an appointment."

……

Restaurant three.

The beautiful waiter brought the food and left a beautiful Russian: "guests, please take your time ~"

Then he left briskly.

Back in the dining area, she communicated excitedly with the ladies and sisters——

"Oh! That guest is very handsome! I guess he must be half blood!"

"But I heard him speak Chinese."

"Will Chinese people have such prominent facial lines?"

"What did he say to you?"

"Unfortunately, there's nothing. He looks a little cold, but he's still handsome."

"Oh! Enissa, do you know you look like you're in love now?"

"I think if it were him, I would."

"Ha ha... Not ashamed!"

A group of beautiful girls from country e were in a group with clear laughter.

The organizer specially arranged a three good restaurant for Xie Dingyuan as his dining place during the event.

Due to their own expenses, few contestants will come here. In and out are some professors, research scholars and staff of the host country.

Xie Dingyuan skillfully cut the steak. In the process, it smells delicious, but he seems to have no appetite.

He couldn't help but go back to yesterday. After Jiang Fuyue deleted his friend, he called Shen Qiannan——

"My Lord, do you know what time it is?! don't I have to sleep?!"

Xie Dingyuan: "I have a question." familiar opening remarks.

Shen Qiannan wailed: "Ya, why do you have problems every day? You don't answer non emotional counseling. You'd better not even open your mouth on academic topics."

Xie Dingyuan: "... Is not a topic."

"Hmm?!" the head suddenly woke up, "that's emotional counseling?"

Xie Dingyuan didn't speak, which is about the default.

Shen Qiannan immediately said, "tell me, what did the girl do to you?"

"She scolded me."

“?”

"And deleted me."

"Ha? Ha ha ha ha -"

"Shen, Qian, Nan!"

"Well, I don't laugh, hahaha... I really don't laugh! Hahaha... I really didn't laugh! Hahaha... Sorry, I can't help it! Ah, I can't help it now! Hahaha..."

Xie Dingyuan: "

The man laughed for five minutes before he stopped.

"Cough... Now, you can say it well."
