An Expert Is actually By My Side

　　 Seven o'clock in the evening.

　　 Hao Yun, who dragged his exhausted body back to the dormitory, unexpectedly discovered that there was no one in the dormitory.

　　 But no wonder.

　　 Today is the weekend, Zhu Kening has a student union activity, Liang Ziyuan seems to have added a guitar club or something like a music club, Zheng Xueqian should go to the library for self-study.

　　 Speaking of the community welcomes myself, I completely missed it...

　　 What club seems to have been added in the last life?

　　 Frowning his brows and thinking for a while, Hao Yun simply shook his head and didn't think about it for the time being. He skillfully climbed the ladder and turned on the bed, lying flat and entered the system space.

　　[Inventory: S-level treasure chest*3]

　　 I didn't expect it to be a treasure chest this time.

　　 This kind of scratching music that has to scratch the prize again after scratching the prize, how does it feel like a Russian matryoshka?

　　 However, the logo with the S-class prefix somewhat comforted Hao Yun, who was exhausted physically and mentally.

　　 S-grade gem?

　　 or some special ability?

　　Hope is a cause and effect wishing machine without side effects...

　　 murmured a few words in his heart, Hao Yun, lying on the bed, reached out and poked the treasure chest icon.

　　 [Congratulations to the host, for getting the "High Mathematics Textbook Full of Professor Lu's Notes"]

　　 Hao Yun: "......?"

　　What the hell? !

　　 Before he could react, an ordinary book of high numbers appeared out of thin air and hit his forehead.

　　 "I rely on..."

　　 The painful tears were almost squeezed out, Hao Yun reached out and took the culprit who hurt him and took a look, almost not surprised by the contents.

I go! Is it really full? !

　　 endured the pain and turned the textbook backwards. The only thing Hao Yun felt was that he was reading a book.

　　 If you ignore the part of the notes and just look at the printed form other than the notes, it will be similar to the textbook he is using. Although the layout is slightly different, the basic knowledge points are mostly the same.

　　According to this statement, will there be any generations of this person in the future? Discrete? Probability Notes?

　　淦!

　　 This guy is too capable of acting!

　　 faintly felt that the name was a bit familiar, but couldn't remember where he had heard it, Hao Yun frowned. However, at this moment, a second row of pop-up windows popped up in front of his eyes.

　　 [Subline: Study carefully and deeply understand the contents of the notes, and independently complete a hundred post-class thinking questions. 】

　　【Reward: Mathematical Attribute +4】

　　 good fellow...

　　 directly add 4 attribute points? !

　　 originally wanted to complain, but seeing the clearly priced task reward, Hao Yun couldn't say anything to complain.

　　 Although he has no particular interest in the subject of mathematics, and was even repelled by some unclear reasons in his previous life, he certainly will not refuse things that can improve his abilities.

　　 only a hundred questions.

　　 Take a while at most.

　　 looked away from this strange high math textbook, Hao Yun continued to look at the remaining two treasure chests.

　　 This time he understood that the treasure chest should be tangible things, and the direct rewards of the task are things that only he can see.

　　 Do you want to continue scratching the prize?

　　 The expression on Hao Yun's face was hesitant.

　　If it’s a book, it’s okay, at most, it’s better to put it up under the pillow. If this is a big guy, such as "the piano of XX," then it is not as simple as a good explanation, but maybe it is life-threatening...

　　 Just then, footsteps came from outside the dormitory.

　　 Hearing the sound of the door lock turning, Hao Yun reflexively tucked the book under the pillow and hid it while lying flat on the bed. The whole set of movements is entirely instinctive, smooth and flowing, and completed in one go.

　　 At almost the same time, Zheng Xueqian carrying a shoulder bag and Liang Ziyuan carrying a guitar walked in from outside.

　　 Looking at Hao Yun lying on the bed, Zheng Xueqian smiled and said hello.

　　 "Oh, why come back so early today?"

　　 Hearing Lao Zheng's voice, Hao Yun responded weakly.

　　 "Tired, come back and lie down for a while."

tired?

　　 Zheng Xueqian's heart suddenly tightened.

　　 I’m afraid I’ve been studying for a whole day...

　　 Especially when he first came in, he faintly heard the sound of the pages rolling.

　　 Is this guy studying while lying in bed?

　　 The more I thought about it, the more I realized it was possible. After playing 2048 in the library for a few hours before, his heart became more nervous in an instant.

　　 Liang Ziyuan glanced at the upper bunk and saw that this guy didn't seem to be joking, and finally put down the guitar that had just been on his knees.

　　Although he thinks he is a more selfish person and doesn't care about other people's nosy, it doesn't mean that he doesn't take care of other people's feelings at all.

　　 The difference between "I can't bear it jokingly" and "I can't bear it physically" can still be distinguished by 　　.

　　 Get a good rest when you are tired.

　　 Without saying a word, he hummed an unknown minor, took out the yellowed draft, and began to write and draw some incomprehensible staff and elusive sentences on it.

　　 On the other side, Zheng Xueqian hesitated for a long time about whether to disturb Hao Yun's sleep, and finally couldn't help but ask.

　　 "Brother Yun."

　　 It's rare that the Ziyuan brothers didn't play the piano indiscriminately today, and Hao Yun, who was extremely comfortable, said lazily.

　　 "Your father is here, let go of the fart."

　　 "Grass! Believe it or not, I threw Lao Zhu's socks on your bed."

　　 Upon hearing this, Hao Yun was immediately happy.

　　 "What? Do you want to help Lao Zhu collect socks?"

　　 was probably disgusted by the imaginary scene, and a retching came from under the bed.

　　 After a long while, Zheng Xueqian, who was relieved, put on a serious tone and continued.

　　 "It's alright, I'm not talking nonsense with you, it's serious."

"you said."

　　 "Have you done the thought problem that you assigned to the high math class last time?"

　　 Thinking questions?

　　 Anything else?

　　 Hao Yun frowned.

　　 "...High math thinking questions?"

　　 "That's right, it was Lao Li's class. Didn't he leave a thought question on the blackboard at the end?" Zheng Xueqian said painfully, "I spent the whole afternoon in the library and didn't get it done."

　　 "Oh, you said that. UU reading www.uukanshu.com"

　　 Hao Yun is vaguely impressed.

　　 At that time, Zhu Kening went to the toilet and gave him papers. He had been distracted during the class and didn't listen very clearly, but the latter thought question was copied on the draft.

　　 But he remembers it seems to be quite simple...

　　 There are two or three letters in total.

　　 Zheng Xueqian couldn't laugh or cry and said: "Don't just write it down yet?"

　　 Hao Yun answered honestly.

"No."

　　 Zheng Xueqian: "……"

　　 "What's the hurry," Liang Ziyuan glanced at Zheng Xueqian and said calmly, "The next class is Tuesday, so I can't write tomorrow."

　　 Zheng Xueqian smiled bitterly and said: "You don't know how difficult that question is."

　　 Liang Ziyuan: "No feeling."

　　 Zheng Xueqian: "Which step have you written?"

　　 Liang Ziyuan: "Solution."

　　 Zheng Xueqian: "……"

　　 Not wanting to talk nonsense with this troublesome guy, Liang Ziyuan looked away impatiently, looked up at the upper bunk, and changed the focus of the topic.

　　 "Brother Yun, can't you sleep, if I don't sleep, I will practice for a while?"

　　 "I'm asleep, good night, thank you!"

　　 quickly closed the curtain, but Hao Yun didn't go to sleep immediately. Instead, he turned on the night light in the curtain and found out the "high math textbook full of Professor Lu's notes."

　　 With a hint of curiosity, he opened the title page of the book.

　　 I saw that the part where the name was written has been erased, leaving only a line of motto written by the author himself——

　　【Science changes the world, mathematics changes science. 】

　　 Hao Yun: "……"

Ok.

　　 Regardless of whether mathematics has changed the world.

　　Single-wheel loading force this one, I Hao Yun would like to call him the strongest!
