"Yes, I'm talking about human beings!" Cheng Nuo said incredibly.

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

"Okay, Xiaojun, hurry up and find a place to park 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?

A look of nostalgia appeared in grandma's eyes.

She is in the United States and has never had the opportunity to bargain due to different languages.

Now that I have finally returned to China, of course I have to kill you!

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

Of course, nothing unexpected happens, Cheng Nuo and the other two, oh no, to be precise, this luxury sports car has indeed attracted countless attention.

I was driving a sports car to the vegetable market to buy vegetables. To be honest, it was not only Cheng Nuo, but also the first time I saw it.

Several little girls holding their boyfriend's arm couldn't help but turn around frequently, looking at the direction of Cheng Nuo and others, making their boyfriend beside him look as dark as the bottom of the pot.

Jiang Jun opened the car door, held his sunglasses, and shook the car keys casually. He wore a brand-name dress, and the Rolex watch on his wrist attracted the charm of the little girls next to him. They all wanted to throw themselves into their arms.

"Cousin, isn't it good?" Jiang Jun raised his eyebrows at Cheng Nuo and said with a smile.

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

"I'm happy." Jiang Jun shook his legs and was still proud.

"Grandma, let's go in and let my cousin show off alone here." Cheng Nuo took the vegetable basket from his grandmother and said with a smile.

"Hey, don't, I'll go too, I'll go too. Grandma must have a lot of things to buy. Cousin, you will be so reluctant, you must not be able to carry it. Don't be afraid, there is a cousin."

Seeing Cheng Nuo and his grandmother's back as they were walking further and further away, Jiang Jun hurriedly chased after him.

…………

This vegetable market is very big, including chicken, duck, fish, meat, vegetables, fruits and melons.

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

There were several people surrounding almost every vegetable stall.

Most of the people who come to the vegetable market to buy vegetables are aunts and housewives. At first glance, they can hardly see men.

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

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

"Sister, don't worry, the one I just picked this morning is definitely fresh!"

…………

"Big girl, I really can't be cheaper anymore. I'm already selling it to you at a cost. I don't make a penny, and I have to pay for labor."

"Then I don't want it."

"Hey hey hey, big girl, wait. Hey... OK, twenty or twenty, I'm already selling it to you because I've lost money. Don't tell anyone else."

…………

Commenting on footsteps and bargaining sounds form a unique melody in the vegetable market.

"It's so lively..." Jiang Jun, as a wealthy young man, has never been to a place like a vegetable market.

"Okay, let's go, go buy some vegetables first." Grandma was familiar with the here.

When I came here, I felt like I wanted to go home. Everyone inside was full of talents and spoke nicely.

Selling meat and selling vegetables are divided into two areas.

The first thing Cheng Nuo and his group came to was the area where they sold vegetables and vegetables.

"Go and 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 buying vegetables. They were all people who only knew how to eat and didn't know how to cook them. They didn't want to buy vegetables with more difficulty. So they nodded and expressed their compliance with grandma's instructions.

Half of the vegetables sell not only one vegetable alone, but most of them put several vegetables on the shelf and choose from them.

Basically, there are spinach sellers at every stall selling vegetables.

Grandma casually found the stall closest to several people in the family.

The stall owner is a middle-aged woman in her forties. When she saw her grandmother coming, she showed a kind smile on her face, "Auntie, what do you want to buy? I have many kinds here."

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

"One piece of sixty-one pound, aunt, can you do some? This is what we just picked last night, and it is definitely more fresh than that in the supermarket." The female stall owner smiled on her face and boasted, "It's not me that I'm bragging, the spinach belongs to my family in this vegetable market. I will not sell those spinach that have been picked for more than one day without my conscience!"

The female stall owner patted her chest and promised her swearingly.

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

"Fake!"

The female stall owner was about to speak with a smile, but a crisp voice from behind her grandmother interrupted the female stall owner's words to speak.

"What you said...is fake!"

Cheng Nuo slowly walked out from behind his grandmother, pointed at the female stall owner with a confused look on his face, and said with a confident tone.

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

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

Cheng Nuo took out a glasses box from his pocket and opened it. It was like Conan's eyes inside.

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

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

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

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

When Cheng Nuo made the action of supporting his eyes, Jiang Jun, who had been paying attention to Cheng Nuo's every move, beat his heart violently. A sentence suddenly rose in his heart.

High-energy warning ahead, please watch Cheng Nuo pretend to behave quietly!

Cheng Nuo stared at the female boss with his eyes examining the prisoner, making the female boss feel that the lower part suddenly became tight.

"If it is newly picked spinach, the normal value of the chlorophyll content should be around 0.3 mg/g, and the color displayed on the leaves should be bright green. It depends on the color of your spinach. The chlorophyll is at most 0.2 mg/g. The synthesis of chlorophyll can be divided into the following four steps: ①②③④…” (Note ①)

"If the roots of the plant absorb magnesium from the soil, chlorophyll is impossible to synthesis. chlorophyll is consumed all the time. Therefore, if it is just picked, the chlorophyll content cannot be directly reduced by 0.1 mg/g."

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

PS: Chlorophyll synthesis steps:

Stage 1: Synthesis of 4 molecules of bile pigmentogen from 8 molecules of glutamate

The second stage: There are 4 molecules of bile pigment to synthesize protophyllum IX, and then combine with magnesium to form monovinyl prochlorophyll ester a

Stage 3: Monovinyl prochlorophyll ester a is reduced by NADPH to chlorophyll ester a under light

Stage 4: Esterification of chlorophyll ester a and phytool to form chlorophyll a
