Eight people rushed up, and because they often delivered takeaways, all six of them had yellow and black complexions, and only two of them were relatively white. Probably because they often go up and down the stairs, the eight people ran very fast.

There was a tall and thin eagle hooked nose who wanted to run over from Wang Tong's right to attack the women. Wang Tong's figure flashed, and he knocked him into the doorway wall with one leg, and then slid to the ground.

Li Bo punched the delivery guy who was talking to him, and his nose bleeded, so he retreated behind the others, and felt the spring (huang) knife in his pocket, ready to make a cold move.

A red-clothed delivery man punched Li Bo in the waist, and Li Bo tried to kick him away, but he held his foot and pulled him down.

A strong man in black, a flying pounce, pressed Li Bo to the ground, Zhang Ling wanted to help, but was pulled by several women, Li Bo waved his hand and said, "It's okay!" and then fought with the two on the ground!

The other four people cooperated to attack Wang Tong, a yellow-faced man made Muay Thai, and his fists did not leave Wang Tong's heart, wrist joints, brain, neck and other vital points, Wang Tong saw that he was vicious, and hit his arm with a punch, breaking his arm bone with a click, and kicking him away!

The other three attacked together, one for Jeet Kune Do, one for Hong Fist, and one for Praying Mantis Fist. Jeet Kune Do attacks the left, Hong punches the right, and Mantis punches the head.

Li Bo punched the strong man in black in the chin, a few teeth and blood splashed Li Bo's face, Li Bo's eyes were splashed with a few drops of blood, and his eyes closed to protect himself!

The yellow-clad delivery man who was hiding behind the person jumped out from behind, flicked off the huang knife, and stabbed Li Bo in the neck.

Zhang Ling exclaimed in surprise and wanted to rush over, but was stopped by Hong Yixin!

Bai Fu's figure flashed, and he kicked the yellow-clothed delivery man to the roof. With a loud bang, the yellow-clothed takeaway fell to the ground, his vest exposed the tip of his spring (huang) knife, blood gushed out, bleeding from his mouth and nose, his eyes were scattered, and he couldn't live!

Wang Tong punched the mantis fist in the chest, knocking him to the ground, kicking Jeet Kune Do with one kick, and then punching Hong away with one palm. The three fell to the ground, and the floor shook.

Li Bo also beat the red-clothed delivery man to a bruised nose and swollen face, and fell to the ground and pretended to be dead. So much happened in just two or three minutes, and the onlookers were stunned!

Seeing that the takeaway brother and his gang were beaten up, the people eating melons outside the door began to discuss.

A middle-aged man eating next door said, "I came back from the bathroom and saw the cause of the incident. The takeaway guy who was beaten to death, drank some wine, went to the wrong room, cheekily, accosted and harassed the fat guy's girlfriend, and became angry after being rejected, abusing the fat guy. was thrown out of the door by the guy, and then he was not convinced, and gathered his accomplices to come up and fight. In the end, he still wants to kill people with a knife, but when he is kicked, hit the roof, and when he falls, he is stabbed to death! If this kind of person dies well, one less person will cause less harm in society!"

Wang Tong smiled at the middle-aged man and said, "Thank you for speaking up, the police will come in a while, please be a personal witness!"

The middle-aged man said, "It's easy to say!"

Wang Tong picked up the phone to call the police, the person in charge of the restaurant said that he had called the police, and then said to Wang Tong with a smile: "Mr. Wang is very sorry! I frightened you! We don't want this kind of thing to happen, but we really have no way, it is impossible to prevent customers from coming to the door!"

Wang Daodao: "I can understand! But I hope you can testify fairly and tell the truth!"

The person in charge of the restaurant hurriedly said, "Yes! You are in self-defense, and we will all testify for you." ”

Then he bowed to the diners around him and said, "I'm sorry! Old and new friends, you've been frightened! All customers who dine today will get a 20% discount!"

A half-aged at the back of the crowd said: "Some time ago, I saw on the Internet that a beautiful woman in Hefei was accosted at a KTV, and after refusing, her sister-in-law was beaten to death, and her husband and brother were injured. I thought this kind of thing was far away from us, but when I came out for a meal, I met it again! Fortunately, the two little brothers know martial arts, otherwise the consequences are unpredictable! No wonder there is a song that 'ugly people live for a long time', and when people are beautiful, they are red and bad!"

A middle-aged man in a suit and leather shoes pulled her away and said: "You can't blame people for being beautiful, the main reason is that some people with bad hearts want to cause trouble! This is when people sit at home, and disaster comes from heaven! You are also very beautiful, and there will be few chaotic places in the future! I don't know martial arts, and I won't be able to protect you at that time!"

The half-aged smiled and said, "Listen to you! Let's go check out!"

The police soon came to Bizhuxuan, then asked in detail about the situation, took pictures, inspected the scene, made a good record of law enforcement, and asked the ambulance to take the injured to the hospital!

Wang Tong once again expressed his gratitude to the middle-aged man Jing Hongkai, and added WeChat friends, saying that he would contact more in the future!

The police then took Wang Tong and his entourage to the police station, made detailed records, and determined that Wang Tong and the others were justified in self-defense.

The police finally asked Wang Tong and the others to go back.

They detained the other seven people who fell to the ground and pretended to be dead for 15 days, and the one with the arm broken, and then executed when the hand was ready, and fined 1,000 yuan each!

Three days later, the robot dogs arrived one after another, and Wang Tong and Li Bo went to the courier company to get the goods back.

The three women control the drive system, and there is a preliminary direction, and the next step is to disassemble various toy dogs. Then compare, borrow, optimize, innovate, and never have the same shape and components, but have their advantages.

Two mechanical engineers, design a variety of robot dog parts, and then use 3D images to demonstrate the assembly, it looks pretty good!

Because it is a small batch customization, not only the price is high, but some manufacturers are still reluctant to do it, Wang Tong and Li Bo had to run to several similar manufacturers and said a lot of good things before they got it done. This is a big challenge to Wang Tong, who is not good at words, but fortunately, Li Bo's eloquence is good, and he often goes to negotiate.

Seeing that the company was gradually becoming regular, Wang Tong withdrew from the company and started other work.

The time has entered June, and in a few days, Wu Meier and Ning Meng will take the college entrance examination.

Wang Tong asked, "Mei'er, Ning Meng, how are you preparing for the college entrance examination?"

Ning Meng said: "It's okay!"

Wu Meier said: "I feel that I have made great progress, and it is no problem to take a key undergraduate exam, but I don't want to study anymore, and it is useless to study in the world now?"

Wang Daodao: "You should take the exam first! After you are admitted, then consider whether to go or not? Leave some time, think more about yourself, and then decide." One more choice is better than no choice. ”

Wu Mei'er said: "Okay then!"

Wang Daodao: "Actually, reading books is useful! First, it can broaden one's horizons and learn more about new things; and second, it can cultivate one's mind and broaden one's mind. Bacon, the philosopher of the British Interception Kingdom, said it well: Reading history makes people wise, reading poetry makes people beautiful, mathematics makes people thorough, science makes people profound, ethics makes people dignified, and the study of logic and rhetoric makes people good at argumentation. However, knowledge is limited by timeliness, region, and number of people, that is, the first thing to know is gold, and the last thing to know is papyrus! The more time passes, the more serious the depreciation of knowledge becomes, so when everyone knows, the value of knowledge is like boiled water, which can only quench thirst, not fill the stomach! It is like having no use! The more developed the region is the faster the information spreads, the faster the depreciation of knowledge, and due to the differences in regional civilization levels, a kind of knowledge is like a treasure in one region and may be like a grass in another region! Take a good exam! When the time comes, whatever you choose, I will support you!"

Wu Meier smiled: "Okay!"

When Wu Meier and others were busy with the college entrance examination, Wang Tong checked the information at home: 1. Product model: EDX 4500H

Product name: X-ray fluorescence spectrometer

Measuring elemental range: from sodium (Na) to uranium (U)

Elemental content analysis range: ppm—99.99% (different elements, different analysis range)

Ambient humidity: 35%-70%

Sample chamber volume: 320mm×100mm

Dimensions: 660mm× 510mm×350mm

Weight: 65Kg

The weight is too heavy, the size is too large, and the elements are measured, not the foods that people are familiar with, vegetables, fruits, grains and oils, or more specifically carbohydrates, fats, proteins, trace elements, vitamins, etc. Eliminate!

2. The multi-functional full-project food safety detector YT-GT210 can quickly detect more than 200 items such as non-edible chemical substances, abuse of food additives, pesticide residues, veterinary drug residues, heavy metals, antibiotic residues, hormone residues, toxin residues, chemical residues, etc. Such as formaldehyde, sulfur dioxide, hanging white block, hydrogen peroxide, nitrite, protein, honey fructose and glucose, sucrose in honey, peroxide value, acid value and so on.

3. Food heavy metal detector YT-SZ05, food heavy metal detector can be widely used in fruits, vegetables, water quality, aquatic products in heavy metals lead, hexavalent chromium, mercury, arsenic, iron, nickel, aluminum rapid detection, testing items can be customized according to customer needs.

4. Meat products detector YT-BH, meat products detector can quickly detect diseased meat, histamine, bacterial toxins, volatile basic nitrogen, the instrument reserves other items testing procedures and ports, according to future needs can be easily increased independent testing items.

5. Ultraviolet/Visible Spectrophotometer, Near-infrared Analyzer, Automatic Titrator, Fluorescence Photometer, Atomic Absorption Meter-Flame Detector

There are too many types of instruments, and the detection is incomplete, and it is impossible to concentrate on a single robot puppy to install it.

It seems that there is only a new stove, Wang Tong thought hard for a few days, and came up with a spiritual energy detection formation jade pendant. By absorbing the spiritual energy of matter, it is black, gray, red, orange, yellow, green, cyan, blue, and purple from low to high. The low-end version is black, gray, and red, the mid-range version is the first six levels, and the high-end version is the ninth level.

Then began to experiment on stone, steel, glass, crystal, jade, ceramics, plastics, wood and other materials, and finally found out that the low, medium and high grade materials are white marble (stone), crystal, jade (jade). The price of these three materials is right, the formation is carved with high power, and the formation is good.

Then a cube of 5 cm on the side of the protective device was made, and once the external force forced to dismantle, the psionic detection equipment would be reduced to powder. There is a feeding port on the front side of the cube, and there is a discharge port on the rear side, and a grain reincarnation cracking array is engraved with a ring at the discharge port. In this way, a esophagus is installed in the dog's mouth, put in the item for testing, and an excretory tube is installed under the dog's tail to eliminate waste. The top surface of the cube is inlaid with white marble (or crystal, or jadeite) in the middle, and a round transparent resin or tempered glass is installed on the back of the robot dog. In this way, the intensity of the aura contained in the object can be observed.

Red is qualified, from red to purple, the darker the color, the more psionic energy. Gray is slightly harmful and is not recommended to eat; black is toxic and harmful, not suitable for consumption; the darker the color from gray to black, the greater the harm!
