Red Envelope System!
Round 61: Contest Ends, Twins are Surprised!

Originally, Lin Fan had only intended to answer the question casually.

At this moment, he decided to play well.

Lin Fan took his questioner like flying, and quickly wrote the complicated calculations on the white paper.

Then, he told Xia Bing and Xia Xue his request and data.

Suddenly, Lin Fan's team heard a crackling and rhythmic sound.

Over time, a prototype of the drainage system gradually appeared on Xia Bing and Xia Xue's computers.

Soon, it's noon.

Many people buy their food directly at the entrance of the lecture hall.

After eating hastily, he continued to solve problems and compete.

Impossible, that's really too much work in mathematical modeling.

If you do not hurry, you may not be able to complete the task within three days.

But Lin Fan was completely different. After having lunch with Xia Bing and Xia Xue, he returned to the empty dormitory and prepared to take a nap.

At this moment, his phone shook slightly.

12:00.

Red envelopes appear!

"Ding! Congratulations, you got 6 yuan."

"Ding! Congratulations, you got 20 yuan."

……

"Ding! Congratulations, you got 10,000 yuan."

"Ding! Congratulations, you got 3 yuan."

Today, Lin Fan received a total of 25,009 yuan.

Then, he glanced at the 818 red packets displayed on the screen.

This is the red envelope I got after I spent 8.188 million yesterday buying a house in Yike City.

Originally, Lin Fan planned to collect 1,000 red envelopes and open them together.

Now, but he hesitated again.

mumbling: "Forget it, turn it on."

"Ding! Congratulations, you got 3000 yuan."

"Ding! Congratulations, get 2 yuan."

……

"Ding! Congratulations, you have gained professional swimming experience. Excellent swimming skills can make you also show great charm in the water!"

……

"Ding! Congratulations, you got 10,000 yuan."

"Ding! Congratulations, you have acquired professional level aircraft driving skills. Even if it was an airplane, it could easily be ridden, and its charm was everywhere!"

……

818 Red envelopes, Lin Fan received a total of 780,922 yuan. And professional swimming experience, professional aircraft driving skills.

78 Million in cash, no problem, but Lin Fan was still very satisfied with the two new skills.

muttering: "There are five more silver red envelopes...Forget it, once the math modeling contest task is done, let's start together."

In this sleep, Lin Fan slept until two o'clock before walking slowly towards the lecture hall.

At this time, everyone in the lecture hall was struggling to calculate and design.

Lin Fan returned to his seat, took a sip of tea, and then started writing at the table.

In the blink of an eye, the sky gradually darkened.

The lecture hall is still bright.

The sound of crackling is endless.

Clearly, many of them did not plan to return to rest at night, and only stayed in class all night.

Lin Fan went straight to the bedroom with Xia Bing and Xia Xue after his time had come.

Life on the second day is similar to the first day.

When Lin Fan was about to return to the dormitory to rest again, the white-haired professor finally walked over and said, "This classmate, tomorrow is the last day of the competition. Don't hurry up and answer the question?”

Lin Fan nodded and said, "OK."

Old professor:...

Ok?

Then, just go?

……

In the blink of an eye, it was the third day.

Mathematical Model Competition is an open book competition, as long as students do not make noise or whisper in the classroom, does not disturb the order of the race.

Therefore, the task of supervising teachers and professors was very simple.

Currently, there was only one professor sitting in the classroom staring at the newspaper boredly.

The other two professors stood in the corridor drinking tea and breathing air.

Among them, a younger professor asked: "Professor Zhao, do you know who Lin Fan was the last time Zhang Yong said?"

The old professor next to pointed to Lin Fan who was sitting in the middle of the classroom, and said, "Hey, it's Lin Fan."

“What is he?” The young professor was surprised.

"Not just because you're not paying too much attention? When you arrive, you will eat and sleep. This is where you come to participate in a mathematical modeling contest. It's just for punching cards, and there's no spirit of holding back any trouble at all." The old professor hated iron and steel.

The old professor said again: "Even the average professor cannot solve that mathematical modeling problem in such a short time."

"Today the competition is over. I don't think he's finished writing his thesis or anything."

The young professor nodded in agreement, and said, "It's a pity."

When the sun went down, the competition finally ended.

"Din!"

After the bell rang quickly.

The old professor stood on the podium and said: "Everyone, stand up! Stop answering questions! Otherwise, you will lose the qualifications for the exam!"

Some people still want to modify the model and polish the paper.

But after hearing what the old professor said, he could only stand up reluctantly.

Lin Fan looked at Xia Bing and Xia Xue, still staring at the computer screen reluctantly, seemingly worried about where her model might go wrong.

"Don't worry, this is already perfect," Lin Fan said.

After listening to Xia Bing and Xia Xue, they seemed to have received the best reward. Both of the beautiful faces were happy and very sweet.

Lin Fan looked at the two of them happily, but could not make a sound. His heart moved a little. He spent 20 million to buy 2 bottles of medical water from the system.

"After you return to the dormitory, drink."

Xia Bing and Xia Xue did not even ask what it was, and hugged them tightly like treasures.

They had just returned to Room 502 of the girls dormitory, holding medical water.

Then, Xia Bing and Xia Xue did not hesitate at all, they opened the medical water and poured it into their mouths.

In their hearts, as long as Lin Fan asked him to do something, they really had to listen.

At this moment, there was the sound of rapid footsteps outside.

A roommate with a melon face, comes in.

After seeing Xia Bing and Xia Xue, he asked, "You're back? How's the math modeling contest going?"

Then, she sat on the bed without waiting for the two to answer, and put on headphones to listen to music.

Because he knew that Xia Bing and Xia Xue could not speak at all, and they simply asked casually.

Xia Bing and Xia Xue still insisted on making a move, indicating that the test was fine.

After a while, the girl with Guazi's face seemed to feel a little stuffy in the bedroom, got up and opened the window.

"Wow!"

Suddenly, a strong wind blew, mixing with pollen.

"Dad!"

Xia Bing and Xia Xue could not help but sneeze at the same time.

After which, they seemed to realize something and slowly opened their mouths.

"what……"

Suddenly, there was a very crisp sound in his throat.

The two looked at each other, their faces full of incredible color.

Then, they seemed to think of something, and they all stared at the medical water bottle they were holding tightly in their hands.
