"Sorry, I've had a cold lately. Huh~~~" Cheng Siwei took out a dirty handkerchief and wiped the runny nose, "Who made this menu?"

Anne frowned, as a life assistant who had served the top rich for a long time, she had an instinctive disgust at the vulgar demeanor of the Asian man in front of her.

"The menu changes every week, and every week the chef makes three menus based on the tastes of the husband and the advice of the nutritionist. Ingredients are procured according to the season, and here is a full list of suppliers. Anne quietly pushed a piece of paper to Cheng Siwei, "Mr. Cheng, if you have other needs, you can ask Kyle, and he will get back to you as soon as possible." ”

This is clearly an eviction order.

Of course, Cheng Siwei understood Anne's words, took the documents provided by Anne, and stood up: "Okay, Miss Anne, if you can think of any doubts, please feel free to contact me, this is my business card." ”

With that, Cheng Siwei took out a crumpled business card from his windbreaker, handed it to Anne, and turned around with his assistant.

"By the way, Miss Anne. As soon as he walked to the door, Cheng Siwei turned back and said, "I remember that in your work record, two months ago, three suppliers were replaced, including the maintenance unit of central air conditioning, right?"

Anne was stunned for a moment and nodded: "Yes, because the previous maintenance unit was acquired, is there a problem with the contract that their parent company re-signed with me?"

"No, no problem. Cheng Siwei grinned.

"Huh~" As soon as he went out, Cheng Siwei lit a cigarette and took a deep breath.

"Cheng, do you think someone poisoned the food?" said the young black man who had been following Cheng Siwei curiously.

Cheng Siwei shook his head: "It's hard to say anything now, but I don't think it's likely that there will be a problem with the food." ”

The young black man's eyes flashed with excitement: "Why?"

Cheng Siwei groaned: "Our employer's security work is quite in place, all food suppliers have done a file tracking, from procurement to import, at least three inspections, tsk, in the end, it is a rich man, it is so troublesome to eat." However, this rigorous inspection process also minimizes the danger of food. ”

"The more intermediaries, the more opportunities there are to be manipulated. The young black man retorted, "What if someone in the middle is bought?"

Cheng Siwei smiled: "I can't rule out this possibility, but think about it, if someone can do this, why don't they just directly poison it more violently and completely kill the target, isn't it more straightforward?

"What's more, the employer only spent one-third of the time eating at his residence in the past two months, and more than half of that time was spent socializing in various places, how did the suspect lock his itinerary?"

The young black man was speechless, and his eyes rolled: "Could it be that no one wants to harm him at all, but he himself is suspicious?" You know, these rich people are afraid of death. ”

Cheng Siwei snuffed out the cigarette in his hand, flicked the extinguished cigarette butt into the trash can, and patted the young black man on the shoulder: "Let's go, James, go to the next place." ”

Cheng Siwei immigrated to the United States six years ago for some reason alone, running a small private detective agency in San Gabriel, Los Angeles.

The reason why it is not large is because he is the only one in this firm. James, a black boy, is his unofficial assistant.

Unlike ordinary private detectives, Cheng Siwei rarely takes on business such as cheating and candid photography, looking for dogs and cats, in a sense, he is more like a real detective, active in the hidden corners of the city.

Three days ago, a friend of Cheng Siwei introduced him to a business that paid him well, but the content of the investigation was very strange, asking him to find the cause of his employer's vitamin B12 deficiency.

Isn't that a doctor's business? Why a detective?

Of course, Cheng Siwei would not ask such a stupid question, although the employer did not disclose his identity, he had already guessed from all kinds of clues that the other party was Zack, a technology upstart who has been in the limelight in the past two years.

Something interesting.

"OK, let's go. Cheng Siwei came down from the ladder, patted the soil on his hands, put the ventilation hood of the ceiling back on, and said to James.

"Where?" James was confused.

"Garage. Cheng Siwei said two words briefly.

"Wow~" As soon as the garage shutter door opened, James let out an exaggerated exclamation.

"It's clearly a warehouse!" James looked around, amazed, "I thought I was at some car show, good, 1, 2, 3, 4。。。。。。 No less than twenty cars!What is that!?F1 cars?"

More than 20 cars, mostly sports cars, including a Ferrari F1, are neatly parked in the garage of thousands of square meters.

Cheng Siwei had a calm expression on his face, flipped through the information he got from his employer, and searched around, "7Z007, I found it, Ferrari F550, in the past two months, the employer has mainly driven this car." ”

Cheng Siwei's footsteps stopped beside the bright yellow Ferrari F550, tapped the engine cover at the rear of the car with his fingers, looked up and smiled at James: "Do you want to try?"

James was startled and excited, "Is that okay? Oh my God, this is the latest Ferrari." ”

Cheng Siwei took off the key from the locker next to the car and threw it to James, and jumped into the passenger seat first, "You are familiar with the road conditions, you come to drive and run a lap at high speed." ”

James is not afraid of the character of heaven and earth, happy fart took the key, and found a cassette of the Eagle Band from the car, the volume was turned up to the maximum, in the deafening music and engine sound, the yellow Ferrari F550 was like an arrow off the string, rushing out of Beverly Hills.

"Oh hoo~~~" James, who got on Highway 10, put down his canopy, felt the wind whistling in his ears, let go of the steering wheel, and raised his hands high, "I am the king of the world~~~"

"I just saw a police car. Cheng Siwei made James honest with one sentence, "How do you feel?"

James showed two rows of white teeth: "Needless to say, didn't you see the way that girl looked at us just now?"

"I'm asking you how the car is. Cheng Siwei said unceremoniously, the wind and the engine were so loud that he shouted, "Don't you often say that as long as you listen to the engine, you will know what kind of car it is?"

James didn't think it was upset, and slapped the steering wheel rhythmically with both hands: "Hey, dude, don't be so serious. This is a Ferrari F550, even if it is not modified, it is the world's top sports car, which can accelerate to 60 miles in 3.5 seconds, let alone change it. Hey, see, as soon as I press this button, the exhaust pipe will breathe fire, want to experience the feeling of nitrogen acceleration?"

Before Cheng Siwei could answer, James turned on the switch of nitrogen acceleration, but unexpectedly, there was no movement.

"Didn't add nitrogen, did you?" James scratched his head, a look of regret.

Cheng Siwei lit a cigarette with a cigarette lighter, "OK, let's go back." ”

James was stunned, unsatisfied, "You're going back so soon?"

Cheng Siwei stretched: "Go back." ”

————————————

"The cost of modifying this car is at least this amount. James stroked the engine of the F550 with one hand, and gestured a number with the other, exclaiming, "I guess I can buy another Porsche 911." ”

"Look at the wiring of the nitrogen acceleration system. Cheng Siwei leaned on the pillar next to him, and kept turning the ring on his ring finger.

"Good. James and Cheng Siwei have been working together for a long time, and when they saw Cheng Siwei's actions, they knew that the other party had entered the detective mode, so they immediately stopped talking nonsense and bent down to investigate intently.

"Strange ... James straightened up, his eyes full of doubt.

Cheng Siwei's eyes flashed: "What did you find?"

James shrugged: "I haven't seen this N2O system, however, there should be a tube connected to the wrong one, you see, this tube is connected to the inner circulation, as long as the car starts, N2O will be released slowly, so, just now when we tried N2O acceleration, it didn't work, N2O has long run out." ”

As expected.

Cheng Siwei squinted, took out his camera, and snapped a few photos of the N2O accelerator.

——————————————————

"Mr. Beard, this is my report, and I ask you to pay the balance of $35,000 within three days, as previously agreed. Cheng Siwei pushed the folder in his hand in front of Thomas.

"Is there any problem?" Cheng Siwei saw that Thomas just looked at the watch and did not open the folder, and asked casually.

Thomas shook his head slightly, and just wanted to speak, but immediately stood up: "Boss." ”

Cheng Siwei turned around and saw a short-haired Chinese young man in a T-shirt walking towards him.

"Mr. Cheng, hello. The young Chinese man had a warm smile on his face, "I'm sorry to keep you waiting, please take a seat." ”

Cheng Siwei raised his eyebrows slightly and sat back on the sofa.

Sure enough, it was he, the youngest billionaire in the world, who bought Apple's Matrix owners - Zack Chang, Zhang Chen.

Zhang Chen didn't do any extra politeness, opened Cheng Siwei's investigation report, turned a few pages, and his eyes were slightly condensed: "N2O?

"Yes, sir. Cheng Siwei shrugged his shoulders, "If nothing else, this should be the reason." We all know that the accelerator used in cars that have been accelerated by liquid nitrogen is N2O. There's a similar modification on that Ferrari of yours. However, there is another name for this thing. ”

Zhang Chen frowned slightly: "What?"

"Laughing gas. ”

The corners of Cheng Siwei's mouth turned up slightly.

"Inhaling a large amount of N2O in a short period of time will make people feel happy, and even laugh, once or twice in a while, and there is no harm to the human body. However, if ingested in low doses for a long time, it will have irreversible effects on the body's nervous system and endocrine. One of the most direct effects is that vitamin B12 cannot be absorbed. ”

"You mean, this is due to the fact that I modified the car?" Zhang Chen said intently.

"Nope. Cheng Siwei grinned, "Your Ferrari does slowly release N2O into the car, but I checked your driving records, and I don't drive long every day." ”

"I found this on the air conditioning duct in your bedroom. Cheng Siwei took out a few photos from the file bag, and on the black background, he could see several jars with a diameter of forty or fifty centimeters, "Inside, they are all N2O." ”

"I think you might need to pay a little more attention to this TOPS building equipment company. ”

With a snap, Cheng Siwei lit a cigarette.
