Kong Shenfeng handed over the hair samples of himself, his wife and Kong Yan to the laboratory for an expedited paternity test.

On the evening of the third day, the appraisal report arrived at Kong Shenfeng's hands, and the report confirmed that Kong Yan was not related to Kong Shenfeng and Kang Yixin.

Kong Shenfeng took the report and returned to the apartment assigned to him by the school in Tokyo in a trance, put the report on the table, and sat in the room for several hours.

It's funny to say, because Kong Shenfeng cherishes every minute of him very much, the last time he wasted time like this was outside his wife's delivery room, 19 years ago, anxiously waiting for his and Kang Yixin's first and only child to come to the world hour.

Kong Shenfeng didn't smoke or drink, and didn't have many good ways to relieve stress, so he could only sit on the cushion, dizzily recalling the past ten years ago until the early morning.

He remembered that once he put a dozen peas in front of the fat and white Kong Xun, and explained over and over again, but no matter what he couldn't make Kong Xun understand why one plus one equals two, so two plus two equals four.Just when he was talking dry, Kang Yixin couldn't stand it any longer, and walked over to complain to him dissatisfiedly, "Stop teaching, the baby is about to cry." Stuffed it in his mouth.

There is also the nervousness when I took Kong Yan to the primary school interview for the first time; the pride when I sneaked out from an important meeting, picked up Kang Yixin, and dressed up to attend Kong Yan’s junior high school graduation ceremony; Disappointment when stacked in a bookcase.

The pendulum in the living room struck twelve, Kong Shenfeng got up and took a few steps, pushed open the glass sliding door of the living room, walked to the balcony, and let the early winter wind blow him awake.

Now is not the time to tell Kang Yixin.

He shook his head, stayed in the cold air for a while, went back to his room, opened his notebook, and drew a rough map.

The map is divided into two lines, the short line is to try to get Ning Yiwei's DNA sample to do a new paternity test, and the long line is to check from the hospital where Kang Yixin gave birth to know the cause and effect of the wrong child.

Kong Shenfeng started to think, and he calmed down. He read the map once, smoothed his train of thought, and wrote a plus or minus 3 next to Kong Yan's date of birth, closed the notebook, and went to wash up.

Early the next morning, Kong Shenfeng contacted his friend who had looked up Ning Yiwei's household registration information for him again, and asked him to find the records of the hospital many years ago for him.

More than ten years ago, the hospital of Liang Qichao's group was only a plan on paper. The medical conditions in D City were not as good as they are now. Kang Yixin had been in D City Maternal Security Hospital during her pregnancy, and she was planning to give birth there.

She booked a single ward in advance, but the plan couldn't keep up with the change. Ten days before the due date, her water broke suddenly, so she had to go to the hospital early.There was a shortage of wards in the hospital, and the single room hadn't been vacated yet. Her water broke and she had no contractions, so she had a strong desire to have a normal delivery, so she stayed in a three-person ward for two days before being transferred to a single-person ward.

What Kong Shenfeng needed was the birth records of the newborn in the hospital for a specific few days, as well as the registration information of the newborn's parents.

He thought it would take a long time to find these things, but unexpectedly, his friend was so powerful that he packed and sent all the materials he needed that afternoon.After Kong Shenfeng finished his work, he went back to the office to open the files, and screened them one by one according to the clues he imagined last night.

According to the newborn records of the Maternity Insurance Hospital, more than 80 boys were born in the three days before and after Kang Yixin gave birth.

If the children had been switched at that time, the difference in body size would not have been too large. Kong Shenfeng narrowed the range of birth weights of boys to within plus or minus [-] grams of the birth weight of his wife's fetus, leaving only ten boys. Taking Kang Yixin's birth date as the zero point of the horizontal axis, Kong Yan's birth time as the zero point of the vertical axis, and the wards of other newborn mothers as the origin of the vertical axis, a coordinate system is established, and the parameters of each fetus are positioned in the coordinate system. Kong Shenfeng found the baby who was most similar to Kang Yixin's child, and his family.

It’s not all about the family, the baby’s mother came to the hospital alone.She gave birth the day before Kang Yixin gave birth, and spent two days in the same ward with Kang Yixin.And at noon on the second day after Kang Yixin gave birth, she was discharged from the hospital.

Kong Shenfeng sorted out his thoughts, first sent the name of the baby's mother to a friend, and asked the friend to help find out her current situation. Then, Kong Shenfeng pondered for a moment, made enough mental preparations, and called Kang Yixin .

When Kang Yixin answered the phone, Kong Shenfeng first told her that he was planning to go back to China this week to spend her wedding anniversary with her. Taking advantage of Kang Yixin's happiness, he turned to the topic he wanted to talk about. Do you remember when you gave birth to Kong Teng?"

"Remember," Kang Yixin said casually, "I've been lying in bed for nine months, and it still hurts for so long."

"Then do you remember the mother who was just admitted to the hospital after the water broke, and was in the same ward as you?"

"Why are you asking this?" Kang Yixin asked suspiciously.

Kong Shenfeng paused, did not lie to Kang Yixin, but did not say anything specific: "I want to investigate the matter, and I will let you know when it is confirmed."

Kang Yixin and Kong Shenfeng still had this kind of tacit understanding, so they stopped asking, thought for a while, and said: "I only remember a single girl with no family members, who is much younger than me."

"single?"

"Well," Kang Yixin was lost in memory, "Did you forget, like a child, seven or eight years younger than me, no one to accompany, don't understand anything, never saw her child's father come, but asked It’s kind of strange to think about it now.”

Kong Shenfeng was silent for a while, then asked Kang Yixin: "Do you remember her name?"

"How can I still remember this?" After Kang Yixin finished speaking, she suddenly paused, and then said slowly, "Oh, yes, there seems to be a dream in her name, a dream of a beautiful dream."

Kong Shenfeng hung up the phone and looked at the baby's note on the scroll: Mother, Shu Meng.

And half an hour later, his friend sent him a message: that Shu Meng died of illness five years ago, she has no relatives, and has nothing left behind.

This was the worst week Ning Yiwei had in his four years in college.

He didn't get in touch with Liang Chong frequently, he was afraid that Liang Chong was busy with something, so he didn't dare to disturb him too much, at most he asked Liang Chong if he ate or slept or didn't eat or sleep based on the meal at Liang Chong's place.

But if Liang Chong didn't come back, Ning Yiwei couldn't calm down.In the Quantum Field Theory class on Friday afternoon, Ning Yiwei even forgot to bring the book, and sat in the first row with Zhou Zirui, the two of them read a book together, their heads were together, as if they were whispering.

Professor Zhou of Quantum Field Theory was very strict, and found that Ning Yiwei not only did not bring a book, but also stared at the blackboard with erratic eyes from time to time, so he called Ning Yiwei's name several times and asked him to answer the questions.

Ning Yiwei returned to his distracted mind, he knew how to answer the questions, and he answered them quickly.Professor Zhou didn't know what was going on, but became even more unhappy.

After finally waiting for the afternoon class to end, Ning Yiwei was going to eat with his schoolbag when he received a call from Kong Shenfeng.

Kong Shenfeng asked Ning Yiwei to visit his office in the research center.

Ning Yiwei asked Zhou Zirui: "Didn't Professor Kong just leave last week, why is he back?"

Zhou Zirui shook his head and commented: "God, ghosts and ghosts appear."

Ning Yiwei went to the research center in a daze, knocked on the door outside Kong Shenfeng's office, and Kong Shenfeng said inside: "Please come in."

"Professor Kong." Ning Yiwei pushed the door in and nodded to Kong Shenfeng.

"Sit," Kong Shenfeng pointed to the chair opposite his desk, and said to Ning Yiwei. When Ning Yiwei sat down, he found the wound on Ning Yiwei's mouth and asked casually, "Yiwei, you What happened to your mouth?"

"I got hurt," Ning Yiwei said vaguely, "It's been a few days since I got hurt, and my blood coagulation function isn't very good, so it's not completely healed."

Kong Shenfeng paused after listening to his explanation, and told Ning Yiwei: "My father also has this problem."

Ning Yiwei didn't know why Kong Shenfeng went so far, but nodded meekly: "My problem is not serious, and it won't affect my life."

Kong Shenfeng nodded, and asked again: "What happened in your quantum field theory class? Just now Lao Zhou complained in our group."

"I forgot to bring the book," Ning Yiwei thought that Kong Shenfeng was looking for him for this matter, and he was a little embarrassed, so he explained, "It wasn't on purpose."

But after explaining, Kong Shenfeng didn't let him go, the two sat silently for a while, Kong Shenfeng asked Ning Yiwei: "Yiwei, do you have something on your mind?"

In fact, Kong Shenfeng is not the type who is good at chatting with others, and it seems that this question was asked boldly. Ning Yiwei originally wanted to deal with it casually, but Kong Shenfeng seemed to add a sentence cautiously: "Yes. You can tell me what's on your mind."

Kong Shenfeng was younger than Ning Yiwei's parents, and his height was about the same as Ning Yiwei's, and slightly taller than Ning Yiwei's.The last time I came back, I probably took the time to cut my hair, and I seem to be more energetic.

As usual, Kong Shenfeng wore a pair of used cotton plaid shirts, with the buttons on the neckline neatly buttoned.Like a scruffy scientific worker, plus a father who doesn't quite understand how to be a father.

Ning Yiwei and him looked at each other for a few seconds, not knowing what had shaken him, and hesitantly said: "You might scold me too if you say it."

Kong Shenfeng smiled at Ning Yiwei: "Tell me about it."

"I want to ask for leave to go to Australia," Ning Yiwei said, "to find someone, but there are classes these days, so I don't know if I should ask for leave."

Kong Shenfeng laughed again, and teased, "Girlfriend?"

Ning Yiwei quickly denied it: "No."

"Then what are you going to do?" Kong Shenfeng asked puzzled.

"His family is in Australia for treatment, and I want to accompany him," Ning Yiwei said. He observed Kong Shenfeng's complexion carefully, and said a lot of unnecessary words, "He is the person I like."

"Oh, young people have to be aggressive," Kong Shenfeng smiled again and said, "How long are you going?"

"I can't say for sure, I want to accompany him until his father's surgery is finished." Ning Yiwei said.

"What surgery? Do you need my help?"

Ning Yiwei shook his head and said, "Heart transplant."

"How can a heart transplant be done in Australia?" Kong Shenfeng frowned, as if he felt something was wrong, and he didn't know where to start guessing.

"His father is recuperating in Australia," Ning Yiwei said. "Suddenly he became ill. He has already found a doctor. On the way there, he is scheduled for surgery tomorrow. He is very sad, so I want to be with him."

Kong Shenfeng probably finally thought of something, his expression suddenly changed, he stared at Ning Yiwei blankly, speechless.

Ning Yiwei thought that Kong Shenfeng must have guessed it, after all he had given so much information, and Kong Shenfeng was so smart.Ning Yiwei couldn't tell what kind of mentality he was telling Kong Shenfeng out of, maybe it was just because of his unreasonable and blind trust in Kong Shenfeng, and what Kong Shenfeng said was the drive of young people.

Anyway, liking Liang Chong is not shameful and there is no need to hide it, everyone will know it one day.

Kong Shenfeng looked at Ning Yiwei, and gradually regained his composure from the shock. He spoke slowly and asked, "Do I know him?"

"I know." Ning Yiwei admitted.

"Do you have a visa?" Kong Shenfeng asked.

Ning Yiwei nodded.

Kong Shenfeng unconsciously grabbed the pen on the table, rubbed the top of the cap of the pen with his thumb repeatedly, and fell into deep thought without saying a word.

After a long time, Kong Shenfeng seemed to have made a decision, relaxed his tense posture, and said to Ning Yiwei in a low voice: "Go if you like."

"I'll ask for leave for you," he said again, "Is the air ticket enough?"

"Enough." Ning Yiwei said.

"Go."
