Chen Bo made a classification of emojis, among which mushroom heads and panda people are the most, accounting for nearly 70% of the number, and most of the rest are pure text, with a little bells and whistles.

"Emojis of the same category can be seen as a closed loop, for example, the Panda Man cannot restrain the Mushroom Head, and must defeat the Panda Man in the way of the Panda Man, but there are special exceptions...."

Chen Bo muttered about the fighting skills taught in the book, and fell into deep thought.

"What the hell is this? The first is a closed loop, and the latter is self-denying that there are exceptions. ”

"Hey, Mr. Wang, how do you review."

Wang Xu was cutting his toenails, he fiddled with his feet, and said with a smile: "The old man has been fighting in the world for more than ten years, and he has never met an opponent, just AI, no problem, within 10 rounds, he will be asked to leave the keyboard with both hands and knock out GG." ”

"Why do I hear this so familiarly?" Chen Bo couldn't remember the original words for the time being, but remembered that it was a famous flag.

Wang Xu said indifferently: "It's a big deal, take less at the end of the term." ”

Chen Bo frowned and asked, "I'll test you, if the other party comes out [you are a younger brother], what kind of emoji should I use to scare back." ”

Wang Xu said without thinking: "There are many, like [you are a younger brother in a younger brother], [dare to talk to your father like this] can be, but you have to choose the best solution according to the situation." ”

"How many situations are there? How much? Chen Bo asked.

"It's a lot.,In case the identity of the AI is your target.,Hehe,Emojis can't be aggressive.,Otherwise, kneel in seconds.。

Wang Xu held his chin and continued: "In the same way, if he is a creditor, you can't use too public, you have to be obscure, understand what I mean." ”

"Well, I understand, it's the uncle who owes the money." Chen Bo didn't know what to do.

"Those who hate each other are basically bad friends and bad friends, this is the easiest, there are no scruples, just do it to the death."

"Did the teacher say the range? Is the exam fixed to an identity? ”

Wang Xu picked his teeth with his fingers and said: "If you want to be beautiful, you will change your identity every round, so you must be careful, and you must not fight the wrong picture." ”

Chen Bo said bitterly: "In ten seconds, I have to find the right emoji again, and I have to judge the right identity, let me die." ”

"It's all about participation, it's about participation." Wang Xu pressed his hand and signaled to be calm, "The exam is only on Friday, and there are still three days to review." ”

Chen Bo complained: "Why is the exam not uniformly arranged at the end of the semester, and it has to be crowded into such a position that does not move forward or backward. ”

Wang Xu was surprised and said: "Our profession is like this, we never play cards according to the routine, others review me on vacation, others go shopping and I pick up the lights, I will always send you an exam notice at an unexpected time, just get used to it." ”

"I hope I don't come here again these days, my thoughts have to slow down, and I haven't used to it for a while."

Just memorizing the Doutu criteria is enough to give Chen Bo a headache, and if he wants to improve the reaction speed in a short period of time, it is estimated that he will have to work hard to study it in the past few days.

"Someone is recruiting substitute teachers in the ticket circle, are you interested?"

"When?"

"Now, it's only for boys, 20 yuan, and I urgently need to be online."

Chen Bo looked at the time and said suspiciously: "It's the last class now, aren't our classes all two class hours?" ”

"Maybe you want to slip in early, some classes are clocked in at the end, and I'll push his business card to you."

"Okay."

Chen Bo, who used to drink Starbucks every day without blinking, would add friends for 20 yuan as a substitute fee.

[Hello, Location & Request]

[Teaching Building 802, help me make a card, I have an emergency]

[802？ ]

Although the dormitory is close to the teaching building, this floor is intimidating to Chen Bo.

[35 yuan, is it not?] Just make a card, if it's fast, it will be done in 20 minutes]

[Here comes brother!] ]

"It's open, it's open, it's finally making money." Chen Bo put down his words, like a madman who had just been discharged from the hospital.

Under the lure of money, Chen Bo ran all the way without taking a breath.

At the door of classroom 802, he saw the father of the gold master, who was a fat man.

"This is a fingerprint film sleeve, and I punched it in with my left index finger." The other party has his own tools, and at a glance he knows that he is a veteran, which is convenient for you and me, and the money is not too easy to earn.

"OK, no problem." Chen Bo put on his fingerprint sleeve and quietly slipped into the classroom through the back door.

"Students, that's all for today's content, now please complete the check-in within the specified time, thank you for your cooperation." The old professor approached the all-in-one machine and started the punch-in system.

Chen Bo sat in his seat, his left hand next to the scanning area, waiting for the voice prompt.

"Please enter the verification code."

"Ouch, there's one more process, it's really annoying." Chen Bo pulled up the desktop keyboard and was ready to go.

"Huh? Is this a captcha? ”

Chen Bo was stunned by the four indefinite integral questions, and there was a countdown in the upper left corner, with a total of only 10 minutes of clock-in time, with an average of 150 seconds for one question.

"Who designed this captcha, please be a person."

Chen Bo didn't bring a pen or paper, so in a panic, he built a new blank drawing board and quickly drafted on it.

"This problem has to use the partial integration method, split the formula into two parts, and integrate the first half first, so the result is..."

Time was passing minute by minute, and Chen Bo's stroke speed couldn't keep up, so he simply calculated by heart.

“1….0….2….4。”

With less than 1 minute left, Chen Bo checked the answer again for the sake of safety.

With the painful lesson of not submitting the answer last time he pretended to be too pushy, this time he learned to be obedient.

"Please place your left thumb in the scanning area."

"Thumb?"

Chen Bo was sure that he had heard correctly, but the fingerprint set given to him by the other party was an index finger, and he was too lazy to care so much about the time.

"Fingerprint recognition is successful, classmate Li Mingfan, you have successfully punched in, overweight, liposuction surgery understands."

"Ahem~, brother, the world is too small." Chen Bo couldn't help but let himself laugh.

More than seventy percent of the students in the class successfully checked in, most of them were divided into groups, one person did a question, and then shared the answers, but Chen Bo relied on his own hard power to clear the customs.

Those students who did not make it would be assigned extra homework, which was considered a disguised punishment, but fortunately Chen Bo was not among them, otherwise he would have been abused in vain and would not have made any money.

"The Art of Punching In? There's something about this course. ”

Chen Bo thought that the next time he scanned the code to punch in, he might be able to play a maze game, walk to a dead end and refresh the QR code directly, so as to ensure that a bunch of students are angry.

The two made an appointment to meet in the dining hall, this fingerprint sleeve is not a disposable item, and they have to return it when they run out.

"Well, take it." Chen Bo took off the fingerprint sleeve and solemnly handed it back to the other party.

Li Mingfan said briskly: "I sent you the money on WeChat, it's hard." ”

"Okay, revisited the indefinite points, where did you go?"

"I was found to be looking for a substitute teacher, and the Academic Affairs Office asked me to talk." Li Mingfan sighed.

Chen Bo said expressionlessly: "Well, I deeply sympathize with this. ”
