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

"Uh......" Jiang Jun still said with a confused expression.

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

How does it feel to haggle...... How long has it been since I felt it?

There was a look of nostalgia in my grandmother's eyes.

She is on the side of the United States, and due to the different languages, she has never had the opportunity to bargain.

Now that I have finally returned to China, of course I have to cut it hard!

There were a few parking spaces next to the vegetable market, and my cousin Jiang Jun drove the car there and stopped.

Of course, it is not surprising that the three of Cheng Nuo, oh no, to be precise, this luxury sports car, as expected, attracts countless eyes.

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

A few little girls holding their boyfriend's arm couldn't help but turn back frequently, looking in the direction of Cheng Nuo and the others with Venus in their eyes, making the boyfriend's face black as the bottom of a pot.

Jiang Jun opened the car door, held on to his sunglasses, and shook the car keys in a chic manner. Dressed in brand-name clothes, coupled with the Rolex watch on her wrist, the little girl next to her was full of brilliance. One by one, they can't wait to give them a hug.

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

"Hehe, commotion. Cheng Nuo rolled his eyes.

"I'd love to. Jiang Jun shook his legs, still triumphant.

"Grandma, let's go in and let my cousin stink here alone. Cheng Nuo took the 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 must not be able to carry it if you suffer so much. Don't be afraid, there is a cousin. ”

Jiang Jun saw the backs of Cheng Nuo and his grandmother walking farther and farther away, and hurriedly chased after them.

............

This vegetable market is very large, chicken, duck, fish, vegetables, melons and fruits, it can be said that there is everything.

Since this market is the largest market in the vicinity, there is a lot of traffic.

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

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

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

"Boss, is your dish fresh?

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

............

"Big sister, it really can't be cheaper, I'm already selling it to you at cost price. I don't earn a penny, and I have to pay for labor. ”

"Then I don't want it. ”

"Hey, hey, big girl, wait. Ay...... Okay, twenty is twenty, I'm already selling it to you at a loss. Don't tell anyone else. ”

............

The sound of criticism and bargaining constitutes a unique melody in the vegetable market.

"It's so lively...... Jiang Jun, who is a rich and noble son, has indeed never been to a place like the vegetable market.

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

When I came here, I felt like I was coming home. All the people in it are talented, and they speak well.

There are two areas for meat and vegetables.

Cheng Nuo and his entourage first came to the area where vegetables were sold.

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

The two of them are completely confused about buying vegetables, and they are all the kind of people who only know how to eat and don't know how to cook. Not to mention the more difficult grocery shopping. So he nodded, indicating that he was following his grandmother's instructions.

Half of the vegetables are not sold alone, but most of them put several kinds of vegetables on the shelves for others to choose.

Basically every stall that sells vegetables sells spinach.

Grandma casually found the nearest stall for a few people in the family.

The stall owner is a middle-aged woman in her forties. When she saw her grandmother coming, she smiled kindly, "Auntie, what do you want to buy? ”

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

"A piece of sixty-one pounds, Auntie, can you come some, this is what we just picked last night, and it is definitely guaranteed to be fresher than the supermarket." The female stall owner had a smile on her face and boasted, "It's not me who blows, in this vegetable market, my family's spinach is the freshest." I won't sell any spinach that lasts longer than a day with a clear conscience!"

The female stall owner patted her chest and swore a promise.

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

"Fake!"

The stall owner was about to smile when a crisp voice from behind her grandmother interrupted her words.

"What do you mean...... It's fake!"

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

"What do you mean, young man?" said the stall owner with an ugly face.

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

I saw Cheng Nuo take out a glasses case from his pocket and open it, and inside were the same eyes as Conan.

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

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

"Weight 583.25 kg, number of blades 34 blades...... The water content was 84.25%, and the organic matter content was 56.24 grams...... Chlorophyll content 0.2 mg/g...... The growth cycle is 41 days...... The inhibition rate of pesticide residues was 65.32%, and the potassium content was ......"

Regarding the various data of the spinach on the female boss's stall, Cheng Nuo already knows it by heart.

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

High-energy warning ahead, please watch Cheng Nuo's boss pretend to be forced quietly!

Cheng Nuo stared at the female boss with the eyes of the prisoner, making the female boss feel a sudden tightness below.

"If it's freshly picked spinach, the normal chlorophyll content should be around 0.3 mg/g, but the chlorophyll in your spinach is 0.2 mg/g. The synthesis of chlorophyll can be divided into the following four steps: (1) (2) (3) (4) ......" (Note (1))

"Without the plant's roots absorbing magnesium from the soil, chlorophyll would not have been synthesized at all. 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 held up a finger and continued.

..................

PS: Steps in the synthesis of chlorophyll:

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

The second stage: 4 molecules of porphobilinogen are synthesized into protoporphyll IX, which is then combined with magnesium to form monovinyl prochlorophyll a

Stage 3: Monovinyl protochlorophyll a is reduced to chlorophyll a by NADPH under light exposure

Stage 4: Chlorophyll ester a and phytol esterification to form chlorophyll a
