Omnipotent Data

"That's right, I'm talking about people!" Cheng Nuo said purely.

"Uh..." Jiang Jun still looked confused.

"Okay, Xiaojun, hurry up and find a place to stop the car, let's go to the vegetable market to buy some fresh vegetables." Grandma said excitedly, holding a vegetable basket in the back seat of the car.

The feeling of bargaining... How long has it been since I felt it?

There was a look of nostalgia in grandma's eyes.

She was in the United States, and because of the different languages, she never had a chance to bargain.

Now that I have finally returned to China, of course I have to chop it to my heart's content!

There are several parking spaces next to the vegetable market, and my cousin Jiang Jun drove there and stopped.

Of course, no accidents, the three of Cheng Nuo, oh no, to be precise, this luxury sports car, as expected, attracted countless eyes.

It's the first time not only Cheng Nuo, but also the crowd in the audience drove the sports car to the vegetable market to buy vegetables.

The little girls who were holding their boyfriend's arms couldn't help turning their heads back frequently, looking in the direction of Cheng Nuo and the others with their eyes full of gold stars, making the boyfriend's face as black as the bottom of a pot.

Jiang Jun opened the car door, adjusted his sunglasses, and flicked the car keys in a chic manner. Dressed in brand-name clothes, coupled with the Rolex watch on her wrist, it attracted the little girl next to her with splendor. Everyone can't wait to throw themselves into their arms.

"Cousin, isn't it good?" Jiang Jun raised an eyebrow at Cheng Nuo and smiled.

"Hehe, angry." Cheng Nuo rolled his eyes.

"I'm happy." Jiang Jun shook his legs, still triumphant.

"Grandma, the two of us go in, and let my cousin show off here alone." Cheng Nuo took the vegetable basket from grandma and said with a smile.

"Hey, don't, I'm going too, I'm going too. Grandma must have a lot of things to buy, cousin, you must be so hard-pressed, you must not be able to carry them. Don't be afraid, there is a cousin."

Seeing the backs of Cheng Nuo and grandma walking further and further away, Jiang Jun hurriedly chased after them.

This vegetable market is very large, with chicken, duck, fish, vegetables, fruits and everything.

Since this vegetable market is considered to be the largest vegetable market nearby, there is a lot of traffic.

In front of almost every vegetable stall, there are several people surrounded.

Most of the people who come to the vegetable market to buy vegetables are aunts and housewives. Looking at the past, there is almost no man in sight.

As soon as he entered the vegetable market, Cheng Nuo could hear the constant commotion inside.

"Boss, is your dish fresh? Why is it so wilting?"

"Sister, don't worry, I just picked it this morning, it's absolutely fresh!"

…………

"Big sister, it really can't be any cheaper. I'm already selling it to you at the cost price. I don't make any money, and I have to pay labor costs."

"Then I don't want it."

"Hey, big girl, wait a minute. Hey... well, twenty is twenty, I sold it to you at a loss. Don't tell anyone else."

…………

The sounds of comments and bargaining constitute the unique melody in the vegetable market.

"It's so lively..." Jiang Jun, a wealthy son, had indeed never been to a place like a vegetable market.

"Okay, let's go, first go buy some vegetables." Grandma is familiar with this place.

Coming here, it feels like coming home. Everyone inside is talented, and they speak nicely.

There are two areas for selling meat and vegetables.

The first thing Cheng Nuo and his party came to was the area selling vegetables.

"Let's go buy some spinach first." Grandma looked around for a week and said to Cheng Nuo and Jiang Jun.

The two of them were completely confused about grocery shopping, they were the kind of people who only knew how to eat but not how to cook. Not to mention the more difficult grocery shopping. So he nodded, expressing his obedience to grandma's instructions.

Half of the vegetables sold are not only selling one kind of vegetable alone,

Most of them put several kinds of vegetables on the shelves for people to choose.

Basically every stall that sells vegetables sells spinach.

Grandma randomly found the nearest stall to the family.

The stall owner is a middle-aged woman in her forties. Seeing grandma coming, a friendly smile appeared on her face, "Auntie, what do you want to buy? I have a lot of varieties here."

Grandma smiled and walked to the stall, pointed to the bundles of spinach and said, "Boss, how do you sell spinach?"

"One piece and six pounds, auntie, would you like to order something, we just picked it last night, and it is absolutely guaranteed to be fresher than the one in the supermarket." The female stall owner boasted with a smile on her face, "It's not me, this dish In the market, the spinach belonging to my family is the freshest. Those spinach that have been picked for more than a day, I will not sell them here against my conscience!"

The female stall owner patted her chest and promised with a strong promise.

"Really?" Grandma said in a slightly puzzled tone.

"fake!"

Just as the female stall owner was about to speak with a smile, a crisp voice from behind grandma interrupted what the female stall owner was about to say.

"What you said...is false!"

Cheng Nuo slowly walked out from behind grandma, pointed at the bewildered female stall owner, and said in a very firm tone.

"Young man, what do you mean?" the female stall owner said with an ugly face.

"Hmph!" Cheng Nuo snorted softly, suddenly feeling something was missing.

Cheng Nuo took out a glasses case from his pocket, opened it, and inside were the same eyes as Conan.

Cheng Nuo put black-rimmed eyes on his face, and Conan's signature confident smile rose from the corner of his mouth.

At the same time, a series of data streams flashed in Cheng Nuo's eyes.

"The weight is 583.25 grams, the number of leaves is 34 leaves...the water content is 84.25%, the organic matter content is 56.24 grams...the chlorophyll content is 0.2 mg/g...the growth cycle is 41 days...the pesticide residue inhibition rate is 65.32%, and the potassium content..."

Cheng Nuo already knew all kinds of data about the spinach on the female boss's stall.

When Cheng Nuo made the gesture of helping his eyes, Jiang Jun's heart beat violently, who had been watching Cheng Nuo's every move. A word suddenly rose in my heart.

High-energy warning ahead, everyone please quietly watch Cheng Nuo pretend to be aggressive!

Cheng Nuo stared at the female boss with the gaze of examining the prisoner, which made the female boss feel a sudden tightness below.

"If it is freshly picked spinach, the normal value of chlorophyll content should be about 0.3 mg/g, but the chlorophyll of your spinach is 0.2 mg/g. The synthesis of chlorophyll can be divided into the following four steps: ①②③④..." (Note ①)

"If there is no plant root system to absorb magnesium from the soil, it is impossible to complete the synthesis of chlorophyll. And chlorophyll is no longer consumed all the time. Therefore, if it is just picked, it is impossible to directly reduce the chlorophyll content by 0.1 mg/g."

"And..." Cheng Nuo raised a finger and continued.

………………

PS: Synthesis steps of chlorophyll:

Phase 1: Synthesis of 4 molecules of porphobilinogen from 8 molecules of glutamic acid

The second stage: four molecules of porphyrinogen synthesize protoporin IX, and then combine with magnesium to form monovinyl protochlorophyllin a

The third stage: monovinyl protochlorophyllin a is reduced to chlorophyll a by NADPH under light

The fourth stage: Esterification of chlorophyll ester a and phytol to form chlorophyll a
