As the door he had just passed through slowly closed, Song Ning couldn’t help but grumble inwardly. The design of this secret door clearly only allowed one person to pass through at a time. Lao San hadn’t even reminded him, and he almost got cut in two by the door. He turned around, about to protest, when he discovered that the underground secret room he was in was brightly lit and filled with various instruments and facilities, resembling a high-tech laboratory.

A female researcher, dressed in a white lab coat and wearing glasses, walked over and said to the third elder with some dissatisfaction, “Master, the rule is that you must come here to collect samples at ten o’clock every day. Today you are half an hour late. If this affects the accuracy of the sampling data and delays the research, we cannot afford to take responsibility!”

Lao San waved his hand and said, “It’s okay, it’s okay, I’m only half an hour late.” He seemed indifferent. Just as the female researcher was about to protest, Lao San pointed at Song Ning and said, “I brought a new research subject. Let’s go, take us to get the samples.”

Song Ning was standing right next to Lao San, but was ignored. When she was told she was to be used as a sample, the female researcher finally noticed her. Her eyes lit up, just like a little girl seeing a new doll, which made Song Ning’s heart pound.

She stared at Song Ning intently, then said excitedly, “A new research subject? Finally, a young research subject! Patriarch, you should have found one like this a long time ago. We’re sure to be able to collect useful data. How long have you been infected?”

“Huh?” Song Ning was bewildered, wondering, “Infected? Infected with what?”

Seeing his puzzled expression, the third brother explained, “When was the first time you and Yuka did it?”

“Oh? Is this your first time? The day before yesterday, I think…”

“Baka!” The third brother couldn’t help but curse when he learned the date his daughter was taken. He was about to say something when he was interrupted by a fanatical researcher.

“Three days after infection? That’s great! We can start by taking samples from the early stages of infection and we’re sure to find something!” the female researcher said excitedly. She grabbed Song Ning’s hand and pulled him forward, complaining, “Master, our teacher said long ago that we should actively infect a patient for research, but you just wouldn’t agree, wasting so many years of research progress.”

The third brother, who followed the two, explained to Song Ning, “Her teacher is Youjia’s mother…”

Song Ning looked at him strangely. If having sex was like infection, then “actively infecting” was just like putting a green hat on this old guy.

No wonder he absolutely refused.

That said, what exactly happened, and what did Yuka infect herself with?

Given that Lao San said earlier that Song Ning was not long for life, could it be that he was infected with some deadly sexually transmitted disease?

The third brother’s grand display was definitely not meant to scare her. Song Ning wasn’t afraid at all. Even if she was infected with some deadly virus in the dungeon, at most she would just fail the mission, not actually die.

The three quickly left the laboratory and arrived at a room with a sign that read “Sample Specimen Room”. As soon as the female researcher pushed open the door, she exclaimed, “Teacher! The patriarch’s sampling needs to be done by you personally today. The patriarch has brought a new infected person, a precious early-stage infected person, infected for three days. The source of infection is a second-generation carrier: Yuka Mikami.”

Before Song Ning could even spot the “teacher” she was talking about, she was led into a room labeled “Rin.” Before the door closed, she finally saw a woman who looked remarkably like Yuka.

“First, the data registration…” The female researcher prepared to record: “Name?”

“Song Ning. What’s your name?”

“Sampling officer: Rin Mikami. Age, height, and weight?”

“22 years old, 178 cm tall, 65 kg. Your surname is San Shang?”

“Source of infection: Yuka Mikami.” Mikami Rin did not answer Song Ning’s question, and then asked, “Date and frequency of sexual intercourse with the source of infection?”

“The day before yesterday, three times. What exactly did you get infected with? Can you tell me first?”

“Once a day? That’s amazing! Sexual intercourse method?” Mikami Rin typed the message quickly.

“The method?” Song Ning asked, puzzled.

“Vaginal intercourse, oral sex, anal sex.”

“Vaginal intercourse and oral sex.” Song Ning gave up on asking questions and answered honestly.

“Number of sexual partners besides those infected?”

“two!”

“Your most recent sexual partner and when?”

“Half an hour ago, with Yuka.”

“Take off your pants.”

“Huh?” Song Ning thought she had misheard.

Rin Mikami repeated: “Take off your pants and check your vulva.”

Song Ning didn’t hesitate and took off her pants, exposing her lower body.

Rin Mikami measured with a soft ruler: “Unerected length: 10 cm, diameter: 2 cm. Erect length: 15 cm, diameter: 3 cm. Take off your shirt too, it will be in the way at this length.”

As Song Ning took off his clothes, he said, “I’m at least 17 centimeters!” Once he was completely naked, San Shang Lin was already standing in front of him with a toolbox, and then slowly knelt down.

San Shanglin disinfected his hands with disinfectant from the toolbox, then lifted Song Ning’s penis with his palm to examine it.
