After returning from the principal's office, Xiao Ran discussed with Yang Chengyou again to confirm some possible flaws in the details, and then sorted out the scratch paper that had written dozens of pages of proof of the process.

"Yes, now the whole proof process is only the most critical step, as long as this equation proof is completed, then it is done!" Xiao Ran smiled with satisfaction after sorting out the manuscript.

"Well, the proof of this last equation, I already have a general idea, and it should be about the same in a few days. Yang Chengyou said excitedly.

A world problem is about to be solved by oneself, which is something to be proud of.

He was already a little impatient and wanted to finish it in one go.

"Don't worry, I'm going to participate in the national training camp for mathematics soon, and I can complete it during this time. Xiao Ran smiled.

In fact, he himself felt that with Yang Chengyou's current mathematical strength, it was a little inappropriate to participate in this high school-level Olympiad competition.

This kid grew up too fast, and Xiao Ran didn't expect that in just over half a year, Yang Chengyou would have a big transformation.

I used to be a problem student, with a low academic performance and a very low sense of existence.

But now he has grown into a cow who can solve the world's problems!

Usually, Yang Chengyou is a child, outgoing and cheerful, and his speech is also whimsical.

But when he started to do things, he was very meticulous, and it can be seen from his entire "Zhou's guess" proof process that he was very careful and handled every little detail very well.

"What do you think about this math camp?" he said to hear what the proud student had to say.

Yang Chengyou scratched his head and smiled, "I haven't been abroad yet, I want to go to a foreign country to feel it." ”

"Well, although the Olympiad is no longer challenging for you today, it is also good to add some life experience. Xiao Ran nodded and smiled.

"Hehe, I think so too. ”

"Okay, let's go back to class, other subjects can't be left behind, and strive to get a top student in the college entrance examination next year." Patting Yang Chengyou's shoulder, Xiao Ran said with a smile.

"Well, this is a bit difficult!!Jiajia and Xiao Zhan are also very strong, I can't guarantee it!" mentioned the top student in the college entrance examination, Yang Chengyou said with a smile.

"Alright, let's go!"

Now the mathematics of the second (10th) class of high school has already been reviewed, so in mathematics class, Xiao Ran always asks them to study by themselves, and if they have any problems, they will find themselves.

Faced with a group of talented and perverted students, Xiao Ran said that there was nothing left to teach.

……

"Brother Ran, come to my place to cook and eat at night, I bought a lot of vegetables. ”

During the lunch meal, Chen Meiyi said to Xiao Ran, who was sitting opposite, while eating the food in the cafeteria.

Since Chen Meiyi came to No. 5 Middle School, they have eaten lunch and dinner together every day.

Whenever they eat, there are always countless pairs of eyes glancing at them.

But they're used to it.

The students who ate in the cafeteria all knew Xiao Ran, and they also admired and respected him very much, so they just cast envious eyes and silently blessed him in their hearts.

"Okay!"

Xiao Ran was stunned for a moment, nodded and agreed.

Chen Meiyi has been here for more than a week, but he has not yet entered her room.

Now Chen Meiyi's sudden invitation made Xiao Ran's heart skip a beat, and she felt a little nervous anticipation.

Today is Wednesday, March 6th, so he has an open class in the afternoon.

Open classes are still very popular.

Students who have attended public classes have recently improved their math scores.

This made them like Xiao Ran's open class even more, and they always fought for a top position.

After school, when he walked out of the classroom, Chen Meiyi was already waiting for him at the door of the classroom.

"Let's go!"

When Xiao Ran saw Chen Meiyi, she also saw Xiao Ran, the two looked at each other and smiled, and walked to the school gate together.

"Brother Ran, let you taste my craft tonight?" will definitely make you linger!" Chen Meiyi followed Xiao Ran's side and said happily and proudly.

"Oh, you can cook?" he looked at Chen Meiyi with a look of surprise, as if he was very surprised.

"Hmph, that's right, my craftsmanship is good, Ma Ma praises me every time!" she said with a proud look on her face.

At this time, the two were already walking along the river, looking at the cute appearance of the person in front of them, Xiao Ran's heart couldn't help but feel hot.

"Really, I'm really looking forward to it, what are you going to cook?"

"Let you try my new dish, mapo tofu!" Chen Meiyi said proudly, "This is the most attentive dish I have learned, you have a good mouth!"

When Xiao Ran heard this, he was also slightly looking forward to it, and the two walked for about 10 minutes before arriving at the community where Chen Meiyi lived.

Chen Meiyi lives in Building 2 408, and the two of them got into the elevator and came to the fourth floor.

This is a newly built community, using the latest technology, I saw Chen Meiyi walk to the door of the room, facing a camera on the door, and the next second, only a nice female voice came.

"Face recognition is successful, welcome home!"

There is a face recognition lock installed here!

"Hehe, that's good!"

Walking into the room, there is a large living room, which is equipped with sofas, coffee tables, TVs, air conditioners and other household appliances.

It is a two-bedroom, two-bedroom apartment, about 100 square meters.

The master bedroom is Chen Meiyi's bedroom, and the side bedroom is used by her as a study, which is equipped with computers, bookshelves, etc.

The kitchen is clean and tidy, it looks like it hasn't been used yet, and it's brand new.

"Brother Ran, you sit on the sofa and watch TV for a while, and I'll cook!" After Chen Meiyi turned on the TV, she pulled Xiao Ran to sit on the sofa, and she got up and walked to the kitchen.

"If you need my help, just call me!"

Sitting on the sofa and watching the variety show "Where Did Dad Go" on TV, Zhang Han brought his 5-year-old son to participate in the show, and the children in it were very smart and cute.

Xiao Ran was envious, thinking, he didn't know when he would have a son or daughter, thinking of this, he couldn't help but turn his head to look at Qianying who was busy in the kitchen.

Half an hour later, the meal was ready, and he went to the kitchen to help serve the food.

"Ouch, that's good, this little green vegetable is fried well, it looks fresh!" Xiao Ran praised a plate of small green vegetables that had been fried.

"Hee-hee!"

After a while, sitting at the dining table, looking at the food on the table, Xiao Ran was stunned.

The other dishes are fine, but only this "mapo tofu" seems to be a little wrong.

I saw a large bowl containing half a bowl of something slightly orange, like a bowl of thick porridge, but the color seemed to be darker, and it looked more like ...... Soaring !!

His eyes widened, he looked at the bowl carefully, and said with some uncertainty: "This ...... This is the mapo tofu you made?"

Chen Meiyi said with a slightly red face: "I think Kuaishou's cooking is quite simple, but I didn't expect that when I actually made it, the tofu was boiled and crushed!"

"You...... You learned how to cook from Kuaishou?"
