Chapter 10 Household Hazardous Substance Detector

  The guard at the door must have received prior notice, "Please wait." He picked up the phone and dialed out.

  Soon, a man drove out of the factory in a four-wheeled electric sightseeing car and stopped beside Sun Zesheng. "Is it Mr. Sun Zesheng? Please get on the car."

  Here, Sun Zesheng didn't have to worry about anyone plotting against him for his wealth or life. He nodded at the driver in a friendly manner and got into the car with his equipment.

  He drove the car and took Sun Zesheng to the office building of the industrial park, then led Sun Zesheng into a conference room on the first floor that could accommodate more than 30 people.

  In the conference room, someone had already cleaned up beforehand, making it look like an interview room, with a clear distinction between host and guest. In the corner of the house, there were also several professional cameras, all of which were aimed at the position of the interviewee.

  Sun Zesheng walked consciously to the position of the interviewee, turned around and said to the person who brought him up: "Can I have a table? Let me put my things on it."

  He nodded, pulled a table from one corner of the room, picked up a disposable paper cup, went to the water dispenser in the corner of the house, and poured him a cup of hot water. "Mr. Sun, please wait for a moment, our General Manager Zhao will be here soon."

  There was a quartz clock hanging in the conference room. Sun Zesheng glanced at the time, and there were still about ten minutes before the scheduled three o'clock. He thanked the man and sat down with a disposable paper cup, sipping water slowly.

  At three o'clock, a noisy footsteps sounded outside the door, and then five or six people walked in from outside the conference room. Except for one woman, they were all men. They were all dressed formally, each wearing a suit and leather shoes that shone brightly. Even though it was hot outside like a sauna, their clothes and grooming were impeccable.

  These people sat down in the interviewer's seat and looked at Sun Zesheng's face one by one.

  Sun Zesheng's expression was calm and composed, his attitude neither arrogant nor humble. He stood up, slightly bowing to the few people, "I am Sun Zesheng, nice to meet everyone."

  The woman in her 40s, dressed in a feminine suit, sat at the far end of the interviewer's table. She exuded an air of sharpness and efficiency. With a glance, she sought permission from the man sitting in the middle, and after obtaining his consent, she opened the notebook she had been carrying with her, looked down for a moment, then raised her head again, and two piercing glints shot out from her phoenix-like eyes.

  The woman pointed to several professional cameras in the corner of the room and said, "Mr. Sun, do you mind if we record this meeting?"

  Sun Zesheng said calmly: "I don't mind."

  The woman in the suit continued, "On the other end of the professional camera is connected to our company's headquarters, where there are more professionals watching the scene here. Mr. Sun, every word and action of yours is being watched by many pairs of eyes, so please answer each question we ask today honestly, without deceit or fabrication."

  Sun Zesheng nodded, "Understood."

  The woman's suit finally entered the formal questioning session, "Mr. Sun, what you said in your self-recommended book is really sensational and exciting. But whether the instrument you developed is as magical as you claimed, we maintain a cautious attitude of doubt."

  "We invited you here today to prove in front of us that what you said is not exaggerated. Only after proving this point can we discuss further cooperation."

  "I understand." To say the least, Sun Zesheng was a very successful businessman in his past life. The only regret is that he was too impulsive and trusted the wrong person. Faced with today's small scene, it's really just a small embarrassment.

  He stood up, walked to the table with the instrument on it, took out the instrument from the cardboard box and connected it to the power source. The instrument was square and smooth at the edges, looking very impressive, so in this regard, the 50,000 yuan entrusted processing fee was not wasted.

  Sun Zesheng cleared his throat and began to speak eloquently.

  "Ladies and gentlemen, this device is a household hazardous substance detector that I invented during my business hours. It can detect various harmful substances that may be present in our daily necessities."

  These daily necessities include but are not limited to solid food, powdered food, drinking water, edible oil, cosmetics, liquor, cigarettes, etc. They can detect dozens of common harmful substances such as dioxin, melamine, nitrate, nicotine, tar, plasticizer, etc. The detection accuracy is less than 0.5% different from professional instruments.

  These words are described in the self-recommended book submitted by Sun Zesheng.

  "Now, I will demonstrate for everyone how to use this household hazardous substance detector to detect various daily necessities. Does anyone smoke?" Sun Zesheng asked.

  A man in a suit pulled out a pack of high-end cigarettes from his pocket and handed it to Sun Zesheng. The packaging box indicated multiple data such as tar content, nicotine content, and carbon monoxide content.

  Sun Zesheng didn't take it, "Just give me a cigarette will do."

  The man in the suit pulled out a cigarette and handed it to Sun Zesheng.

  Sun Zesheng took out several disposable gloves purchased from a supermarket, opened the packaging of one set in front of several interviewers, put on the gloves, stripped the cigarette, placed the tobacco in the instrument's detection slot, and then pressed the switch.

  When Sun Zesheng operated the household hazardous substance detector, several cameras in the room started working and took pictures of him from multiple angles to prevent him from cheating in front of several interviewers. At the same time, the live video was also recorded and transmitted to the headquarters of Zhenmei Holding Investment Co., Ltd. thousands of miles away.

  Thirty seconds later, a "ding" sound was heard, and a set of data appeared on the instrument's display screen, indicating that the test results were out.

  Sun Zesheng didn't rush to show the test results, and he smiled at the man in the suit, saying: "Sir, before today, we didn't know each other, you're not my entrustment, right?"

  The man in the suit smiled and said, "Of course not."

  Sun Zesheng said: "Does anyone have any objections to the relationship between the two of us? If not, I will report the test results."

  The woman was somewhat impatient, "Mr. Sun, this is not a close-up magic show venue, you don't need to create atmosphere here, just hurry up and report your test results."

  "Alright, the test results are: tar 13mg, nicotine in smoke 1.1mg, carbon monoxide content in smoke 14mg. Smoking is harmful to health, please quit smoking." Sun Zesheng read out the test results one by one.

  The man in the suit turned the cigarette pack over to the side with the harmful substance content printed on it, and compared it one by one with the results displayed on the instrument. To his surprise, there was not a single deviation.

  "That's right! Absolutely right!!"

  A small commotion occurred in the conference room, but it quickly subsided. Sun Zesheng's home had a hazardous substance detector that couldn't even pass the test for cigarettes, or else there wouldn't be this appraisal meeting today.

  The woman beckoned towards the outside of the conference room, "Bring over all the things we prepared beforehand."

  Someone pushed in a stainless steel cart with over ten items to be tested, including edible oil, vinegar, soy sauce, drinking water, cosmetics, bagged milk and canned milk powder.

  The woman said, "Mr. Sun, these are the items we have specially prepared for this meeting. Each of them contains common harmful substances. We hope you can use your invention to detect them."

  "There's one thing you need to be clear about. We had already found a professional testing organization to test them beforehand. We hope that the detection result of your instrument can match the detection result of the professional institution by more than 80%, otherwise, we will not consider any form of cooperation with the instrument you developed."

  Her words are a bit difficult, if the accuracy of this instrument can reach 80% of the professional detection results, it already has a considerable prospect for commercial development. And in many companies, when developing related instruments at the beginning, the effect is often very poor, but they will still continue to invest heavily in research funds.

  Of course, from another perspective, it cannot be said that the Zhenmei Group is making things difficult for Sun Zesheng. After all, the Zhenmei Group is not a charitable organization and any investment they make is done with returns in mind. Moreover, this time Sun Zesheng took the initiative to come to them, so it's only natural that they would have high demands for the household hazardous substance detector he developed.

  Sun Zesheng had every confidence in his instrument, and without saying another word, he began to test. Almost every few minutes, he would finish testing one and report the results orally.

  One after another, I detected seven or eight kinds, and none of them were wrong!

  The people sitting in the interviewer's seat had increasingly good expressions on their faces. They have already started whispering to each other, exchanging opinions quietly.

  At this time, Sun Zesheng picked up a bottle containing a light yellow edible oil and poured a small amount into the detection groove. After a while, the household hazardous substance detector emitted an ear-piercing alarm - it was gutter oil, refusing to detect.

  Those men and women in formal attire were taken aback at first, then burst out laughing. However, after the laughter subsided, the middle-aged man sitting in the center of the interviewer's seat spoke with a serious face.

  "Mr. Sun, you should know that up to now, neither the Ministry of Health nor the State Food and Drug Administration has established a detection standard for gutter oil in our country. How can your household hazardous substance detector determine it is gutter oil?"

  The voice of him speaking should be that senior executive vice president who called Sun Zesheng and asked Sun Zesheng to come over for a demonstration.

  Sun Zesheng said calmly, "As everyone knows, the largest source of gutter oil is the grease trap in the kitchen sewers of large restaurants in cities. They were originally a dull, turbid and slightly reddish paste, but after only a short period of filtration, heating, sedimentation and separation, they are transformed by unscrupulous traders into clear 'edible oil' that emits a foul odor."

  It can be imagined how poor their quality is and how unsanitary they are.

  In gutter oil, in addition to recycled edible oil and repeatedly used frying oil, there are also starch, protein, grain particles, vegetable residues, etc., which may also contain a large amount of wastewater, garbage, detergent, etc. Moreover, pathogenic and carcinogenic substances such as aflatoxin and benzoapyrene are also common. In addition, it is also possible to contain highly toxic substances such as arsenic compounds.

  The household hazardous substance detector I developed mainly uses spectral imaging technology, which inputs a large amount of contrast information in advance and produces judgment results by comparing the spectrum generated during the detection of hazardous substances.

  The senior executive vice president asked: "So can't we extract this part of the function and make it a separate ditch oil detector? And those comparative information, how did you get them?"
