Cheng Mo and Mr. Shen went to the supermarket together, this was the first time for Cheng Mo, he knew for the first time that there were so many famous vegetables and fruits, he listened to Mr. Shen pushing a small cart to introduce him to what vegetables have higher nutritional value, generally speaking, the darker the leaf color of the vegetable, the higher the nutritional value.

For example, spinach, rape, bok choy, chrysanthemum, kale, etc. Chinese cabbage and cabbage are not counted because their leaves are too light in color, which means that the nutrient content is not up to the standard for dark green leafy vegetables. Some flowers and mosses with high nutritional value and dark green color also belong to dark green leafy vegetables, such as green cauliflower, rape moss, etc.

I also heard Mr. Shen tell him to distinguish between ordinary vegetables, pollution-free vegetables, green food vegetables, organic vegetables and other food labels.

In addition, it is best to buy vegetables and fruits, choose plastic wrap and store them in the freezer, because after harvesting, when placed at room temperature, vitamins will decompose very quickly, but the content of toxic nitrite will rise rapidly. Therefore, vegetables should be stored in the freezer rather than in the open air. Plastic wrap can delay water loss and reduce nutrient loss.

After buying a bunch of things, Shen Youyi asked, "Isn't it boring to listen to me?"

Cheng Mo shook his head, "It's interesting, I haven't studied these things before, and I rarely go to the supermarket....."

For Cheng Mo, these things are knowledge that can't be learned from books, and they are a kind of life experience, although Mr. Shen is not luxurious, he is a very meticulous and exquisite person, and the taste of life and the richness of the spirit are very important to her.

"Actually, I don't just choose, I also plant...... When I was a child, there was a small yard at home, there were no flowers in the yard, all the vegetables planted by my grandmother, every spring my grandmother would buy seeds back, I would help turn the soil, apply base fertilizer, build scaffolding, and when the leaves grew out, I would also help catch insects, loosen the soil, weed, and watch those leaves and fruits grow up little by little, which is quite fulfilling. In summer, the vines of cucumbers and beans climb all over the yard, the round watermelons planted in the pots have not grown very big, the bamboo bed can smell the aroma of melons and fruits in the corridor, the starry sky is vast, listening to my grandmother shaking the fan to read "Dream of Red Mansions" to me, it is really happy!"

Shen Youyi said very nostalgic, but Cheng Mo was very uninteresting, "Won't you be lifted up by mosquitoes and fly to the sky?"

"I hate it!" Shen Youyi chuckled and patted Cheng Mo, "Of course I will smear the flower water and light mosquito coils, but I will still be bitten, I thought at that time! If I find a boyfriend in the future, it must be because when I encounter mosquitoes bullying me, I will push him out to block mosquitoes, and he doesn't dare to say no....."

Cheng Mo sighed, "So now there are fewer and fewer mosquitoes in the city, and Sister Xi doesn't need a boyfriend anymore." ”

Shen Youyi didn't expect Cheng Mo to joke, holding the cart with one hand, covering his mouth with the other and laughing, she didn't know that this sentence got to her laughter, she smiled and bent over, her body was trembling slightly, and there was a nipple shake on her chest, like someone gently shaking the two fruitful grapes hanging on the vine trellis.

"I'm not afraid of mosquitoes, I can catch you now and tie you up for mosquito bites....."

"Sister Naxi miscalculated, mosquitoes prefer people like Sister Xi, and mosquitoes don't like people like me. Cheng Cheng said it really.

"Why?" Shen Youyi asked, holding back a smile and straightening up again.

"Because I tell bad jokes, and mosquitoes are afraid of the cold. ”

Shen Youyi lowered her head again, covered her mouth, and tried not to laugh out loud, but she couldn't stop her shoulders from shaking, "I know why Xie Minyun likes you." ”

"Why?" he rarely asks others why, but he also knows that when it's time to do a good job, he has to do a good job.

"Because the weather in Star City is so hot, the iceberg girl is about to melt without your cold jokes!"

Shen Youyi saw that Cheng Mo's expressionless face was still a poker face, and an unstained sunset appeared on her cheeks, she let go of her hand holding the cart, raised two crosses, pressed the corners of Cheng Mo's mouth, gently lifted it upward, and made an artificial smile to Cheng Mo, "The first time I tell a joke, I have to laugh...."

It turns out that Mr. Shen will also be unreasonable.

So Cheng Mo smiled.

Laughing seriously.

——————————————————

After Mr. Shen had dinner, Cheng Mo went home, it was rare for Cheng Mo to give up his study plan, and spread out a piece of paper under the dim lamp, he already had a lot of ideas about this mysterious chalk drawing, in order to make the context clearer, he had to write him down.

Crime time: Every weekend to Monday at half past five in the morning.

The perpetrator is able to know or observe when the security department reactivates the monitors, and is familiar with the routes and processes of security patrols.

.......

Cheng Mo wrote a full page of clues collected today, remembering that Mr. Shen said that this was a question from the other party, so he picked up his mobile phone and sent a message to Fu Yuanzhuo, asking him to help collect the photos of the paintings that had appeared on the blackboard, and the security department was all video screenshots, not clear enough, not very clear in detail, if this is a topic, then there should be hints in these paintings.

Soon Fu Yuanzhuo replied and said that he would give it to him tomorrow.

Cheng Mo collected his thoughts for a while, and began to speculate on how the other party instantly made the painting appear on the blackboard, the earliest Cheng Mo thought that the other party controlled the monitor through hacking methods, and kept repeating the picture, but Director Wu denied this statement, not only because the school's monitoring system is difficult to hack, but also because they are patrol and monitoring double insurance, and when Monday morning is approaching, they will be extra vigilant.

Therefore, the perpetrator does not have the possibility of staying in the classroom for a long time, but the blackboard painting is not an ordinary painting, just paste it, so a fine painting is not something that can be achieved overnight, even if Cheng Mo uses a carrier, there is no way to make a pair of chalk drawings magically appear on the blackboard in an instant, so the painting must be on the blackboard from the beginning.....

But when did the other party put the painting up, and how did the surveillance and security turn a blind eye to the painting?

Cheng Mo had a headache thinking about it, and he didn't go to bed until almost eleven o'clock in the evening, and incarnated as Lin Zhinuo to go to Yinyan, and he still didn't come when he woke up that night, Cheng Mo decided to warm up his relationship with Gao Yuemei a little, and sat in the card seat of the college doctor for about half an hour that day.

He believed that Kevin would tell Jing Xing all this.

The next morning, Cheng Mo and Fu Yuanzhuo went to the first (9) class of high school, and the two of them studied the blackboard for a long time, but they found that this was a very ordinary blackboard, without any organs, Cheng Mo thought to himself, the blackboard is estimated that Teacher Shen and Director Wu have already checked it.

Cheng Mo asked Fu Yuanzhuo to get the floor plan of the school teaching building, like most high school teaching buildings, there is a long corridor facing the playground, and on this side of the corridor is a row of six classrooms, and the classroom of the first (9) class of high school is on the far left, far away from the cafeteria.

The structure of the teaching building is very simple, as long as there is enough light, all the classrooms in the corridor can be seen at a glance, there is no possibility of ghosts, and the investigation of the case is somewhat deadlocked.

At noon, Fu Yuanzhuo finally collected all the paintings that appeared on the blackboard in the last school year and sent them to Cheng Mo, who quickly browsed them, and before he had time to study them carefully, he was ready to go to Teacher Shen's dormitory first.

In order to finish, Mr. Shen opened a small stove for him.

Fu Yuanzhuo and Yan Yitong asked Cheng Mo where he was going, and Cheng Mo excused himself by saying that he would go outside the school for physical examinations every Tuesday and Thursday in the future, and he couldn't eat, and Fu Yuanzhuo and Yan Yitong didn't suspect it.

After prevaricating, Cheng Mo went around the school in a circle and went straight to Teacher Shen's dormitory.....
