Chapter 5 The first lesson

"Su Han, have you really decided?" The office decorated with classics, it seems that a lot of money has been spent, it is not evening, the sunset is not seen, but it gives people a strange sense of gloom, a young man stands facing a man in a sitting suit, the man in the suit sighs and looks reluctant.

"Yes, Richard, I've decided." Su Han replied very simply, "In the future, it's okay to give me a name from the 'Fengluo Editorial Agency', but I will definitely come back if there is something, and I will go to N Academy to start a new life." ”

"Huh." Richard smiled, "You kid, you're really cunning." It's exactly like good buddies complaining about each other's shortcomings, "You haven't made a move since the beginning, you're all giving advice, and you want to finally get rid of the relationship and maintain a white body with no bad records?" Richard's eyes gradually changed from initial indifference to as sharp as a falcon.

"Richard, you're mature." Su Han didn't hide his motives, everything he did was to better protect his sister. "Not only as a leader, but also mature in thinking, I can't hide this bit of my mind from you."

"yes, hehe." Richard tried his best to keep Su Han, "Su Han, you deliberately didn't hide it, I still sincerely invite you, with your wisdom, we can make more of a difference, isn't it great?" Richard stood up, leaned close to Su Han with both hands on the table, and tried his best to persuade him.

"I," Su Han smiled freely, "I still yearn for a bright life." Richard gently pressed Richard and sat down, "Be careful with Lue in the future, and besides, my sister is waiting for you at home, don't let her wait." Su Han said and turned around and walked out, the meaning of this time had already been brought, and he didn't expect to take a different path with his good brother who had fought hard at this moment.

"Su Han, are we still brothers?" Richard asked Su Han with his back to him.

"Do you still love my sister?" Su Han turned his head, did not answer, and asked rhetorically.

"Holding the hand of the son, growing old with the son, the sea is dry and the stones are rotten, and this will not swerving." Richard replied firmly.

"I'll take this answer." Su Han and Richard both smiled slightly, silently swore to each other, turned their heads, and Su Han walked out easily.

"I'm always welcome, Su Han," Richard said silently after Su Han left.

Su Han walked through the corridor, and a gust of fragrant wind accompanied a beautiful young woman walking towards him. Su Han smiled, not moved by the beauty in the slightest, the young woman was still holding a baby in her arms, facing Su Han's smile, showing her endless charm, and returning the smile, and then, the two of them just passed by. Both sides didn't even look back, as if they had known strangers for a long time.

Feng Shishi walked into Richard's office with Li Tengfei in her arms, "That kid is really a good boy with pure feelings." Feng Shishi praised Su Han without shying away from it in front of her husband. It is really the most perfect dream lover for thousands of women in the future. "As he approached Richard, he made a big decision." Richard, let's go see my sister tomorrow. ”

"Well, this day has finally come, Shishi, you and Qian must get along." Richard stretched out his hands, "Come, give me a hug." ”

"Be careful, don't wake him up when the child is asleep." Feng Shishi became a mother for the first time, and she paid attention to infinite love for the swaddling clothes in her arms.

"I know," Richard said, with a happy expression.

――――――――――――――――――――――――――――――――――――

Hey, why is this the case again, it seems to be back to the days when I first entered the "Fengluo Editorial Agency", so I still miss it. This is Su Han's first class as a teaching assistant, and it is quite tragic as a teaching assistant, after accepting the invitation of Vice Dean Fan Youming, the class he was assigned to turned out to be a teaching assistant for an elective teacher. This class is very strange, although the sparrow is small, he has a teaching assistant for this teacher, but Su Han has never seen this boss once, what is the situation?

Walking into the classroom and seeing the students who came to class below doing their own things, Su Han seemed to understand something: this course is very cheating, and the elective course "On the Philosophy of Thinking Brings What Kind of Efficiency Does the Philosophy of Thinking Bring to Learning". It seems that there are unspoken rules for this course, and the teacher himself is estimated to help look at the attendance, and the students below cooperate with the attendance, regardless of whether everyone is here or not, so that one eye is turned a blind eye, in short, everyone works together, easily adds credits, and gets it done in one step.

Su Han thinks that he has prepared a lot, in order to make a good impression on the students for the first time as a substitute teacher, and also to make up for the regrets of the university he has not attended. Glancing at the messy blackboard behind him, Su Han picked up the eraser and decided to do something first, and then started the class. "From today on, I am the teaching assistant of your elective course "On the Philosophy of Thinking What Kind of Efficiency Does It Bring to Learning", but it is obvious that the teacher did not come, so I will substitute for the class first, my name is Su Han" After Su Han introduced himself politely, a few people looked up at him, and some of them looked up at him instead of him but on the blackboard, and the others were still doing it by themselves, so Su Han felt a little cold. Anyway, why is it the same situation every time? No wonder I miss "Fengluo Editorial Agency", everything is difficult at the beginning! I miss the days when everyone worked hard together in the "Fengluo Editorial Agency", but unfortunately, Richard's guy can't turn back, and he has already started to be strangers with him?

After the cold field, he held the board eraser in his hand, turned around, and wiped the blackboard clean, these are all prepared by the students in advance, and now they are doing it themselves, you can imagine how cold this course is. Just as he was about to wipe it, a flat-headed college student with glasses who was struggling to write suddenly stood up, pointed at Su Han, and shouted in an anxious tone: "Hey! The one in front, don't rub it! Move! I haven't finished my notes yet! Obviously, I didn't listen to Su Han's self-introduction, or I didn't pay attention to it at all.

Very arrogant tone, Su Han glanced at the blackboard to be erased, it was a board book of high mathematics, the last class was a high mathematics class, this class was an elective course, the boy was most likely not to report this class, but was in a hurry to finish taking notes, Su Han had already finished analyzing. This shout also disturbed the whole class and aroused their onlookers.

"This question is actually very simple," Su Han smiled slightly.

"Simple, simple fart! You dodge first, and I'll do whatever you want after I finish remembering! The boy motioned with the tip of his pen for Su Han to go away.

Su Han was unmoved, a little angry, and clenched his fists, "The tone is not good, is this the usual attitude towards others?" "Every time he says a word, the decibel gradually increases, he is a man who has made a cruel plan, and the expected bloodshed has been calculated, will he be afraid of a student shouting?" How about a bet? Su Han suddenly showed a harmless smile from humans and animals, but if this smile is placed now, it is a harbinger of the iconic "pretending to be a pig and eating a tiger".

"Bet, bet on what?" The boy couldn't feel what Su Han was going to do.

"I'll give you the answer, and you can sit here honestly and listen to the lecture." Without waiting for the boy to react, Su Han interrupted him, "Yes, I know you didn't report for this course, and I also know that you understand that this course is very cold. Just finish this class here for free, this is the minimum respect between people! ”

"I, I see." That boy still looks down on Su Han a little, what kind of person, he is about the same age as himself to be a teaching assistant, and I don't know if he is a mistake.

"Prove that the equation x3-4x2+1=0 has at least one real root in the interval (0,1)" Su Han began to write and clearly reproduce those vague traces, "It's very simple, let f(x)=x3-4x2+1=0, and find the derivative of 3x2-8x."
