Without sterile gloves or latex gloves, Zheng Renhe looked straight at a glass of red urine on the table.

It's really red, or very uniform. But it doesn't look like gross hematuria, because hematuria is slightly turbid, not a very "clear" red liquid.

Zheng Ren is a little confused. What is this? If we can exclude the factors of water, food and drugs, we can only consider that it is a rare disease.

But the big pig hoof didn't give a diagnosis!

On the other side of the water cup is Su Yun.

Across the water cup, Zheng Ren saw that Su Yun's eyes were big, like the eyes of demons in the abyss of blood. It's the same if you want to come to Su Yun to see Zheng Ren.

Slightly stunned, they looked at each other across the glass of red urine, silent, thinking about the possibility.

Zhang Fuya did not urge, but waited politely.

A few minutes later, she got up and went to the bathroom.

When Zheng Ren heard the footsteps, the faint idea in his mind seemed to come out again.

Damn it! What exactly is the idea?

He couldn't catch the glimmer of inspiration. Although it is so close, so within reach.

Wait

Zheng Renmeng stood up and asked, "Miss Zhang, wait a minute."

"Huh?" Zhang Jianya stopped, turned back, green silk and powdered noodles, very beautiful.

"Frequent urination is possible, but you seem to go to the bathroom too often. If so, consider that it may be diabetes insipidus." Although Zheng Ren vaguely grasped a trace of ideas, he was still uncertain and could only grope forward in the dark.

"You..." Zhang Fuya stared at Zheng Ren like a fool.

Zheng Ren hasn't met this kind of look for a long time, except that it often appears on Su Yun.

"Boss, can you stop being so ignorant of life." Su Yun said contemptuously, "Miss Zhang goes to make-up, not to the bathroom. Isn't it normal for girls to make-up?"

"Er..." Zheng Ren felt embarrassed, but it was this embarrassment that made his thinking run faster.

"Makeup? Every ten minutes?" Zheng Ren immediately understood the situation.

"..." Su Yun also realized that the problem was wrong.

Zhang Fuya was stunned and mended her makeup. Is there anything wrong?

"Miss Zhang, I think I already know where the problem is." Zheng Ren smiled.

"What's going on?" Zhang Fuya asked in a trembling voice.

"Lipstick!" Zheng Ren said, "the problem is lipstick."

Su Yun suddenly, his eyes filled with joy and said, "yes, it's the problem of lipstick colorant. Miss Zhang, you mended lipstick three times in the 52 minutes I came in?"

Zhang Fuya doesn't remember how long it took, but she did mend her lipstick three times.

"The colorant of lipstick contains pigment or dye. The pigment used in lipstick must be fine particles to evenly adhere to the lips. At present, the most widely used soluble coloring dye is bromate red." Su Yun said briskly.

Zhang Jianya's "disease" has been very clear.

"Of course, bromate red dye is also divided into natural and chemical products. The Guerlain 09 you use is a natural colorant, which does little harm to human body. Because you have a habit of using lipstick at least 30-50 times a day, the colorant is absorbed into your body and excreted with your urine."

Before speaking, Su Yun actually didn't know where the specific problem was. But his mind turned very fast. Zheng Ren had a hint. He went on and felt more reasonable the more he said.

Until finally, Su Yun smiled, his black hair floating on his forehead.

He knew that he... The boss found the truth.

"..." Zhang Fuya was stunned.

Colorant, I know. I have to wear lipstick many times a day. It's true. Is there 3 or 50 times... It's estimated that it's almost the same.

But are these related to hematuria?

"Well, Su Yun is right." Zheng Ren smiled: "Miss Zhang, you are under too much pressure. The way to reduce pressure is to make up or apply lipstick to make yourself look better, right?"

Zhang Fuya nodded vaguely and said, "yes, I really don't look well recently, especially in the past six months. I tried to make up with lipstick, which can make me look more energetic, so..."

"That's it." Zheng Renchang breathed a sigh of relief. "Su Yun has said the whole process. The treatment method is also very simple. Go back to plain face for 3 days. Don't put on lipstick. See if the color of urine has changed."

"Really?" Zhang Fuya looked at Zheng Ren suspiciously.

"This is the only reasonable explanation now." Zheng Ren said with a smile, "because it's a high-grade lipstick and the colorant is a natural ingredient, the damage to the body is very small. Moreover, you don't use lipstick frequently for a long time. No organic lesions were found in Heyang's laboratory examination."

"But even so, in another year or so, little will add up and form organic lesions. Now it's still time to correct it." Zheng Rendao.

Su Yun smiled with a relaxed face and black hair floating on his forehead.

"..." Zhang Fuya was speechless.

"If it's all right, we'll go. In fact, don't always think you're too tired. Who's not tired?" Su Yun looked at Zhang Jianya and said seriously, "isn't it tiring to be a doctor? I was called to you halfway through the meal and stared at the urine for a long time."

Zhang Jianya blushed and was a little ashamed and angry. But at the thought of the two "abnormal doctors" looking at the glass, they couldn't say what they wanted to say.

"So relax. At least you still have a chance to make money. Many people can't make money if they want to." Su Yun whistled and looked frivolous, like a little ruffian squatting on a horse's teeth to tease the girl.

It's just that this local ruffian is a little handsome, earth shaking. In the face of his "flirtation", both Zhang Jianya and her little assistant blushed.

"Focus on stability." Zheng Rendao.

"Tell the truth." Su Yun said with a smile, "you look good. Have confidence in yourself. Don't use lipstick for the time being. Add a wechat and tell me the situation in a few days."

Su Yun's words seem to have magic. Zhang Jianya has no objection or other ideas. She exchanged wechat with Su Yun.

"Follow the doctor's advice and don't put on lipstick yourself." Su Yun said with a smile.

When they walked out of the room, Su Yun asked, "thirty or fifty times a day, my lips are not afraid to be damaged. This obsessive-compulsive disorder is really heavy enough!"

"Not only the lips, but also the kidneys may be broken later. It's okay to apply lipstick, but if the amount is too large... It's wrong to have a large amount of anything." Zheng Ren said with a smile, "what do you say?"

"Stop bullshit. Hurry back. They shouldn't have dispersed yet." Su Yun said, "before I was full, I squatted and looked at red urine for a long time. You say, how can I drink red wine in the future?"
