The life of the combination of work and rest is the most comfortable, he worked tirelessly in the office for a day, and the landlord only won a few thousand dollars after hundreds of fights, and now he came home for dinner, of course, it is impossible to continue to work tiringly, lying on the chair to take this blending analysis, complex analysis to relax the brain and see, in the leisure self-cultivation and self-cultivation at the same time to improve their ability level, why not?

However, the undergraduate algebraic geometry is just an introduction, only talking about some basic algebraic clusters, generalizations, etc., and the more difficult topology and modern analysis and advanced probability theory are actually not too difficult.

The really difficult part is the mathematics course that enters the doctoral stage, although it is also mathematics, but because of the strong specialization, it can be said that it has achieved the realm of "interlacing like a mountain".

Lu Li secretly thought, I think the matrix should not be too much to use the professional mathematics of the doctoral stage to design games, right?

Luo Qiaoqiao sat on the side to prepare for class, as a Chinese teacher, she is very responsible for students, and usually prepares for class in advance, but Lu Li still saw her preparing for class next to him for the first time, curiously picked up a few tutorials for preparing for class and flipped through them, and quickly threw them away boringly, the language learned by junior high school students is too simple, there is really no meaning in reading it, those simple classical Chinese, Lu Li can still memorize it backwards now.

He really didn't understand why the current students were complaining, and Luo Qiaoqiao often had a headache for the few students in the class who were not studying well.

"Are those students still doing the same?"

Lu Li asked casually.

"Well, after calling the parents, their grades still don't improve significantly. ”

Luo Qiaoqiao looked unhappy when he talked about those students with extremely poor grades.

"In fact, interest is the best teacher for learning, if they are not interested in learning, no matter how much they are forced to learn, it is not of much use. ”

Thinking that he was interested in Li Bai at the beginning, he memorized all the poems in "The Complete Works of Li Bai", and this proves that as long as he is interested, learning is not a problem at all.

Of course, the most basic root cause of poor learning is that you are too ugly.

"But how do you get them interested?"

Luo Qiaoqiao was puzzled.

"Well, let's do more homework, there is too little homework for children now. ”

At the beginning, Lu Li didn't like to study and skipped a lot of homework, but now that he looks back, he regrets it very much.

There was nothing to say all night, and early the next morning, Luo Qiaoqiao ran over and knocked on the door of Lu Li's room.

"Do you really want to go there so early?"

"yes, I'll have to put on makeup when I get there. ”

"Well, okay. ”

promised to accompany Luo Qiaoqiao today, Lu Li would not object, tidied up his clothes, and helped Luo Qiaoqiao carry a suitcase and walk out.

Luo Qiaoqiao is not alone, there are many office workers like them who like this kind of cos hobby, they usually gather in a group to chat with each other, and their respective Weibo accounts send some pictures.

Luo Qiaoqiao just likes cos, but she doesn't have too much in-depth contact, so she doesn't have a Weibo account to post selfies. The place where I met with my girl friend was next to the nearby subway station, and when I walked over, I saw several men and women wearing wigs standing there from a long distance.

"Qiaoqiao!"

The first woman in a green wig waved her white arms and signaled that they were here.

"Dwarf Ledo!"

Calling each other's nicknames, Luo Qiaoqiao ran over and hugged the "dwarf Leduo" with a green wig.

"That's what it is...... Your boyfriend?"

The green-haired woman let go of Luo Qiaoqiao and turned her head to look at Lu Li, who was walking over.

Before getting Lu Li's permission, Luo Qiaoqiao would not send a photo of her boyfriend to the other party without permission, so she only said that she would come with her boyfriend, and the green-haired woman didn't care much about it, but when Lu Li came over, she suddenly stood in place.

Not only her, but also the man and two women next to her were also shocked, Luo Qiaoqiao's appearance is indeed very cute, and she is definitely a lovely girlfriend in the hearts of ordinary people, but walking with Lu Li made several green-haired women feel that Luo Qiaoqiao is "unworthy".

Originally, I wanted to laugh at Luo Qiaoqiao a few times in advance, but after the green-haired woman finally reacted, she forcibly suppressed the jealousy in her heart and smiled reluctantly: "Qiaoqiao, don't you introduce your boyfriend?"

"Hmm, Brother Lu, this is 'Dwarf Leduo', 'Baa', 'Director Cai', 'Green Cauliflower'. ”

It's all their own nicknames, but Lu Li doesn't mean to know these men and women in depth, he nodded slightly, and didn't speak, just watching Luo Qiaoqiao introduce himself to them.

After close contact, Lu Li realized that the "vegetable director" who he thought was a man before was actually a woman dressed as a man, but the green cabbage was a man dressed as a woman.

He couldn't understand what these people were thinking, women dressed as men, men dressed as women?

There were a few people who were talking and laughing, but after seeing Lu Li's very cold response to them, a few people somehow always felt that in front of Lu Li, Luo Qiaoqiao's boyfriend, they had a sense of depression that they couldn't speak loudly, and they didn't even dare to speak quietly, and walked forward in silence all the way. Luo Qiaoqiao didn't notice anything wrong at all, and talked to Lu Li with a smile all the way, not knowing that the friends behind him were angry and didn't dare to come out.

The convention and exhibition center is a distance from here, fortunately it is not time to work, they rushed to the convention and exhibition center a long time in advance, it is easy to get in, the green-haired woman "short Leduo" seems to be very related, and especially found a make-up room to use, the general cos does not have this relationship.

The women went in to put on makeup, and Lu Li stood outside curiously and scanned the surroundings.

It's still more than an hour before the start of the comic show, but a lot of cos wearing various hair colors and costumes have already walked in, and there are people setting up stalls on the ground, and various official personnel are making the final arrangements everywhere.

If Lu Li was to talk about it, the demon flurry was his first impression.

He glanced around, and the people who walked by him were also shocked, quietly looking at him, still wondering what role Lu Li was cos.

"Huh?"

Lu Li was suddenly taken aback, and looked at the group of people walking dozens of meters in front of him in surprise.

Those people......

Wearing a variety of masks.

And they were all masks that he was very familiar with, all of them were assigned by the participants who had participated in the matrix games in the past.

Aren't the masks and trench coats worn by the people walking in the middle exactly the same as the ones he wore during the East China Sea incident?

This is in ...... Cos Facebreaker?

If you want to say that cos' is quite similar, from Lu Li's point of view, he feels that these cos face-breakers have paid a lot of money, not only completely imitating his clothes, but even the mask is disguised decently, and he basically can't see any loopholes.

It's just that the figure is too bad.
