Merchant and doctor

The building where Wanjia lives has a total height of 12 floors, with two rooms on one staircase. Wanjia is located in the middle unit, on the third floor, room 305.

As soon as he entered the door, Bian Mu found that this house was still a large one, with two bathrooms, one large and one small, and two kitchens, one Chinese-style kitchen and one Western-style small kitchen. The living room area was much longer and wider than that of ordinary residents, and there were three bedrooms. The layout is very reasonable.

Unlike ordinary homes, there are many oil paintings hanging on the walls of Wan's house. The number is obviously far beyond the normal decorative function.

Not only that, the ceiling in Wanjia's living room is also very unusual. The dome design style is made of glass, flange, fine porcelain... and is made of glass, flange, fine porcelain... by the hands of skilled craftsmen. It is actually arranged to look like the starry sky in the universe, with the Big Dipper, the solar system, and the Milky Way. ...Not to mention, the design is quite clever.

"It's a good idea to come to our home for an inspection. Otherwise, no doctor could imagine out of thin air that this family could go so far in terms of light and shadow visual pollution." Bian Mu thought to himself.

Seeing Bian Mu looking up at the roof of her home intently, Ms. Wan couldn't help but boast a few words: "Doesn't it look good? My eldest grandson designed it and asked a professional team to come over to build it. At night, when the lights are turned on, the sky is filled with dazzling lights and the universe. Under the eyes, during festivals, children will also shine some laser lights on it, making it look weird, full of wonder and arouse people's imagination."

Smiling slightly, Bian Mu was noncommittal.

Ms. Wan was slightly disappointed when she didn't hear a positive response. She took a few steps forward with a slightly embarrassed expression and asked her husband to make Dr. Bian a cup of fragrant tea.

"Don't bother, I'm not thirsty! Please close all the doors and windows, and let's do some medical tests." After that, Bian Mu took out three high-grade retractable triangular triangles made of carbon steel from the backpack he carried with him. The stand holds it up.

Then, using steps as a ruler, Bian Mu repeatedly measured and calculated for a long time, and finally determined an obtuse triangle.

Fortunately, the sofa and other furniture in the living room are not in the way.

Bian Mu took out 3 napkins on the coffee table. He kneaded them into 3 small paper balls and threw them on the ground, marking the obtuse triangle just now.

He measured it again using steps as a ruler, and felt that the angle was slightly off. Bian Mu stretched out his foot and kicked the small paper ball a few times, trying his best to adjust the angle to what he thought was the best angle.

That's it!
Bian Mu placed a very delicate triangular stand at the location of each small paper ball.

Ms. Wan and her wife are both highly educated. Compared with ordinary ordinary citizens, they have naturally seen a lot of the world. In their opinion, the tripods used by Dr. Bian are so exquisite and complicated. The equipment used on the stands are professional and professional. There is no need to say more about the advanced level.

Sure enough, the two of them saw Bian Mu take out a very delicate small wooden box, put on white professional dust-proof and anti-fog gloves, and took out a standard prism with a cross diameter of about ten centimeters from the small wooden box, which looked like glass, crystal, or jade. That's okay... It's colorless and transparent, occasionally emitting a ray of purple light. No matter how you look at it, it exudes a rare sense of high-end.

There is a ready-made holder on the bracket closest to the large floor-to-ceiling glass window of the balcony, and Bian Mu set the prism on it and adjusted it repeatedly for a long time.

On the bracket in the middle distance, Bian Mu placed a piece of azure blue crystal stone, which is blue and blue, occasionally refracting a ray of red light, which is somewhat dazzling.Finally, Bian Mu placed a camera-sized receiving center on the remaining bracket. The power cord of the USB interface is very long and long, and Bian Mu connected it to the Wanjia power socket.

After turning on the switch, turning on the power, and making a few simple adjustments, Bian Mu opened and adjusted the folding optical lens, temperature probe, photocatalyst integrated reactor, polarization capture meter, and sextant on the middle end of the receiver one by one.

Mr. and Mrs. Wan walked slowly forward and looked at it curiously. They recognized the polarization capture device, photocatalyst integrated reactor and sextant.

After looking at each other for a few times, the two guessed that the test done by Bian Mu should be related to the level of ultraviolet rays. However, because the receiver in front of them looked too complicated, they really didn't know what data Dr. Bian was preparing to test.

……

More than 20 minutes passed, and Bian Mu finished the first phase of the test.

After adjusting the angle of the observation triangle again and replacing it with a more sophisticated and refined receiving terminal, Bian Mu tested it for more than half an hour.

……

For the third time, Bian Mu adjusted the type and angle of the prism, and finally replaced a receiving terminal that looked more precise. This time, Bian Mu connected five test tubes around the terminal, in which some unknown solvents were titrated. Finally, Bian Mujia stuffed a piece of test paper of a different color into each small airtight test tube. After a while, all the small test tubes began to bubble.

After setting the scheduled time, Bian Mu invited the Wan family to sit on the sofa in the living room.

"I believe I have some guesses as to what my intentions are. Yes, I am doing photochemical pollution measurement, which includes interior decoration glass media testing, olefinic hydrocarbon residue testing, nitrogen dioxide concentration testing, and general light pollution testing. Standard evaluation... So far, your family has moderately exceeded the standard, which is the main cause of Aunt Wan's eye disease. After a while, the evaluation results will be printed out." Bian Mu explained with a smile.

"The equipment you use looks advanced enough. Although your clinic looks unusual, it's not like you usually have such advanced equipment. A piece of money shouldn't cost more than a million?" Ms. Wan still spoke straightforwardly.

"Haha... I'm afraid it's more than 300 million. Where can my small clinic get the money to maintain such expensive professional equipment? I borrowed these things from Xiaobailou. Speaking of which, it's all for the sake of a friend of mine. ." As he spoke, Bian Mu briefly introduced the origin and nature of Xiaobailou to the two elders.

"No wonder you look different from ordinary Chinese medicine doctors. It turns out you are an expert doctor in our city! No wonder our students highly recommend you to us! Disrespect, disrespect!" As he spoke, Ms. Wan's wife He bowed his hands to Bian Mu.

"Don't dare to take it, don't take it! I got in by chance. In terms of medical skills, I'm still far behind! Let's go on to talk about Aunt Wan's condition. It stands to reason that there are many houses in the same geographical location and close to your home. Yes, especially in summer, polluted gases such as car exhaust on the street and mixed street exhaust will also drift into their homes with the wind. This is the same in every household. I have done a brief investigation before entering your house. Then why What is the worst situation for our family? The problem lies in the glass products used in your home decoration. At the same time, in order to pursue lighting, your family overuses large-sized glass, which amplifies photochemical pollution many times. In addition, there is this !" As he spoke, Bian Mu stretched out his right index finger and pointed at the cosmic galaxy on the roof.
