My system can be changed

"It really is a veritable mysterious organization."

oh?Seeing that Lin Haoyu agreed, Yang Gaofeng's expression turned serious, and he smirked excitedly, saying:

"Don't worry! As long as you can do it, I will give you five hundred five-star praise!"

Rub, isn't it a good review?

Anyway, I am also a student of Tsinghua University, so it should not be a problem to do a simple programming to get good reviews.

Of course, it is not known whether it is counted in the backstage of Tiantuan and the mysterious system in Lin Haoyu's mind in the end.

Yang Gaofeng was ecstatic in his heart. This final question was a test at the end of the school year specially given by the teacher. If you pass it, you can directly get a scholarship, and even the principal will personally award prizes and so on.

"I, Yang Gaofeng, can finally feel proud for a while."

Yang Gaofeng giggled silly, clenched his fists to cheer himself up, and didn't even notice that he didn't do it himself at all.
After entering the door, Lin Haoyu saw that Yang Gaofeng did not follow, but hid aside to eat Malatang, so he sat down at the desk and pulled the paper casually.

"Ok?"

Slightly frowned in surprise and looked at it for a long time, but Lin Haoyu didn't have the slightest clue, so he couldn't help thinking secretly:
"System, are you sure this is really a mission included in the food delivery?"

What the hell!

Whose system will allow the host to deliver food?And also encountered these messy things.

After a long time, the system trembled suddenly, and replied with a ding:

"Ding! The host's takeaway full-level skill is activated. Since the host needs to complete mathematics at present, the takeaway full-level skill will give the host three 10-minute temporary advanced mathematics (full level) skills."

Swish!
As soon as the words fell, Lin Haoyu felt a warm current flow from his brain to his whole body, and finally turned into waves and returned to his mind.

Lin Haoyu was stunned for a moment, then glanced at his skill bar in amazement, and said in surprise:
"System, what the hell do you mean, as long as there is a request from a takeaway customer, this takeaway skill will give me the corresponding skill?"

That's a lot of money!
Lin Haoyu's eyes suddenly brightened. He originally thought that this full-level takeaway skill was a weak point. It could neither increase the skill of his old driver, nor increase the money and fame he got from the takeaway——

But, who would have imagined that a takeaway skill actually contains all the skills? !
"Gudu."

Lin Haoyu swallowed with difficulty, heart palpitations secretly:

"In this way, having the delivery skills is equivalent to mastering all the skills."

Terrible!Food delivery is indeed one of the most mysterious industries in the world, and Lin Haoyu has already felt the charm of it just because he is new to this industry.

After being stunned for a full 2 ​​minutes, Lin Haoyu finally came to his senses. He immediately shook his head, put aside his messy thoughts, narrowed his eyes seriously, and began to read the questions.

"Simple math problems."

Lin Haoyu's mouth curled into a wicked smile, and he began to write directly on the answer sheet with great confidence, without even looking at the draft paper.

With a full grade in advanced mathematics, even if he is asked to do the final question of a graduate student, he can easily complete it, let alone the final question of a university.

"Shhhhh."

There was a flurry of flamboyance, until the answer area on the answer sheet was full, and Lin Haoyu didn't see the intention to stop writing, so he continued to pull another piece of draft paper and continued writing.

After about 10 minutes, even though Lin Haoyu tried his best to streamline the answering process, he still only answered about three-quarters of it.

"Fuck, it seems that after reaching the full level, it's not a waste of time to think, but a waste of time to write."

Lin Haoyu frowned, his forehead was covered with cold sweat, and the veins on his right arm were bulging due to exertion, which was very scary.

After writing hard for about 8 minutes, I finally finished all the finale questions before the full-level advanced mathematics skills disappeared.

"Clap."

call!Lin Haoyu threw the pen directly to the corner, heaved a long sigh of relief full of fatigue, clicked his tongue and sighed:
"It seems that it is a bit tiring to do the finale directly."

Twisting his wrist, Lin Haoyu got up, talked to Yang Gaofeng and left here, and continued to deliver the next takeaway, not taking this episode seriously.

A few days later, in the Department of Mathematics of Tsinghua University, Yang Gaofeng sat anxiously in his seat, waiting for the teacher's evaluation on the podium.

"Gudu."

There was a sound of swallowing saliva with difficulty, but unfortunately it was not Yang Gaofeng's, but the teacher who was correcting the test paper on the podium.

"This, how is this possible?"

The teacher opened his mouth wide and stared wide-eyed in horror, without any image at all.

Before entering the classroom, the teacher had already thought about how to tell the students that the finale of the last question was actually one of the most difficult puzzles that had never been solved in the entire mathematics world for a hundred years—but now this What the hell is going on? !

There was a flash of disbelief in the teacher's eyes, and then he looked carefully at the answering process of the question.

Touching the bridge of his nose, the teacher scratched his head from time to time in amazement, and even occasionally turned on the computer and didn't know what to look for. After thinking for an entire hour, he could barely calculate the three-line process.

"Not bad at all."

The teacher almost petrified in the classroom, what the hell!This guy actually solved at least three lines of a problem that he hadn't thought about for a hundred years!

Miracle!
Even if all the following steps are incorrect, the correct results of these three lines are enough for this guy to win a Huaxia-level award.

Gudu, struggling to pull out an ugly smile, the teacher immediately announced the dismissal of the get out of class in a panic, then found a gap and immediately flew towards his office, and at the same time called the owner whose name was on the test paper, Yang Gaofeng.

At this moment, Yang Gaofeng is also rushing towards the office behind the teacher with a dazed expression on his face:

"Huh? What happened again? Why didn't the teacher say a word during the whole class."

When he came to the office, the teacher calmed down a little, reacted, and quickly put the test paper on the table with trembling hands in shock, narrowed his eyes slightly pretending to be calm, and stared at Yang Gaofeng carefully.

"Yang Gaofeng, did you really write this test paper? Tell the truth!"

The teacher pretended to be serious and stared at Yang Gaofeng. After all, even in mathematics, it is impossible for everyone to solve such a difficult problem in such a short period of time.

"This"

Fuck, the teacher actually found himself in the office, which means that the matter is not small.

Yang Gaofeng was startled suddenly, and secretly exclaimed:

"Could it be that the takeaway guy I'm looking for is too bad at mathematics, and the questions he made are really wrong?"

After pondering for a long time, Yang Gaofeng felt shaken. If he didn't admit it, wouldn't he be scolded by the teacher?
Coughing a few times in embarrassment, Yang Gaofeng scratched his head embarrassedly with a smirk and said:

"Hey, teacher, I asked a delivery boy to do this for me."

To be honest, even though Yang Gaofeng had prepared for it long ago, it would be too embarrassing for such a Qinghua college student to ask a delivery boy to help with homework, no matter how you say it.

The smirk on Yang Gaofeng's face gradually twitched, and finally disappeared slowly. Instead, he pretended to sigh angrily:
"I knew this kid was unreliable, and I couldn't even understand the messy things he made."

Takeaway brother?

The teacher blinked his eyes slightly in surprise, stood up suddenly in surprise, covered his mouth in shock and shouted:

"What did you say?"

When did even a food delivery guy easily solve a mathematical problem that had not been solved for hundreds of years in the world in half an hour?
What the hell!

The teacher silently swallowed his saliva, so as not to get too excited later and choke himself to death:
"Yang, Yang Gaofeng, do you know what you're talking about?"

Even those math professors in their [-]s and [-]s would not be able to solve this worldwide mathematical problem. Even Gauss, who is praised by everyone, is not a panacea for mathematics. A large number of conjectures are almost unsolvable.

But now, a world problem that has been solved is placed in front of her.

Yang Gaofeng cleared his throat in embarrassment, and said with a guilty smile:
"Then teacher, well, the main problem is that this delivery boy can't do math at all, he's just a fucking piece of trash."

wipe!
Yang Gaofeng secretly looked gloomy. If it wasn't because of this guy's messy behavior, how could he be discovered by the teacher?

"Damn it, I knew I wouldn't ask you to help me with the questions."

In Yang Gaofeng's eyes, Lin Haoyu was just an uneducated food delivery man, and it was normal for him not to be able to do math problems at Tsinghua University.

"Ugh!"

The teacher narrowed his eyes slightly, quite dissatisfied with Yang Gaofeng's attitude.

It could be seen that Yang Gaofeng was not lying, but the teacher was slightly disappointed.

"I didn't expect him to be my student."

The teacher frowned and laughed at himself, that's right, if his student really confirmed one of the world's millennium conjectures in his hands, he reckoned that he was really lucky.

"That's right, except for the first three lines, the next three lines are also completely correct."

The teacher secretly felt palpitations, and at the same time, she exerted her knowledge-seeking spirit as a teacher and continued to ponder over it carefully.

The content is only six lines, but the teacher did not know dozens of pieces of draft paper before he finally came to the correct conclusion. He couldn't help feeling more and more in awe of this mysterious takeaway boy.

"Gudu."
