470 points for independent action, and unity is strength.

"I didn't care about anything else and immediately went to the room, only to see the bag I had given to Qingqing drop in front of the elevator."
"I was very anxious at the time, so I quickly went upstairs. I knocked on the door for a long time and no one opened it. I didn't have a room card in my hand. When I was about to give up, the door opened..."
At this point, Xia Fan closed his eyes.
"How was it?" Tang Xinze looked at Xia Fan and asked again.
Xia Fan opened his eyes, "A man, I seem to have seen him before but he is not familiar, he just pulled me into the room in one go, and then step by step towards me, then..."
Subconsciously, Xia Fan touched her neck.
Tang Xinze immediately bent over to check, and there was indeed a small red dot on Xia Fan's neck, which should be a needle mark.
“So, the man who opened the door knocked you out, and then tied you up. When did you wake up?”
“I heard my phone ring while I was still a bit groggy, but I couldn't move. I screamed for help, but no one came to help me, until just recently, when they finally arrived...”
Xia Fan pointed to the two men at the door.
Tang Xinze looked at the two men, then looked at Xia Fan.
"They untied me, and I immediately went to find my phone. I found that my younger brother had called me many times. My younger brother is also a police officer and will come over soon."
“He asked me if the person who tied me up was... Dr. Luo Jingcheng, a surgeon from San Third Hospital. I looked at the photo, and it's him.”
“I already know about this person, but the specific situation in City A hasn't been clarified yet. Maybe we have to wait for Captain Xu to come before we can talk about it.”
"But Qingqing may be in danger. Can you find her first?" Xi
"Xia, don't blame yourself, it's not your fault. Our colleagues have already gone to check the surveillance footage. We are living in the information age now, we can check the surveillance footage, it's better than just speculating around by ourselves."
Tang Xinze comforted Xia Fan.
But her hands were still tangled together.
……
In the car—
Xia Sen suddenly shouted.
“Found it…”
“Hurry, tell me.” Xu Yingzhi looked at the time on the phone's navigation, it was getting faster. After driving for so long, they were finally almost there.
"I found a medical record from overseas, this is the medical situation of Luo Jingcheng in the United States when he was twenty years old. It is clearly written on it that he is a congenital azoospermia patient."
"Sure enough it's him, no wonder he's so unbridled. How did you find out?" Xu Ying asked.
"I first checked Luo Jingcheng's personal information. His English name was registered in the hospital database, and he did indeed study abroad before."
"So I searched in this direction, entered his English name, and found his medical records."
"By combining the patient's date of birth and other information, I finally identified the medical history of Luo Jingcheng."
“However, he was very cautious that there is no medical record in China for this matter, which means he did not seek treatment for this disease in China and always went abroad for treatment.”
"There have been two or three times before, but they were all denied. It's an incurable problem."
"No wonder Qingqing told me that Sui Rui has always liked children and said that not having children is not her problem. Sui Rui should have known about Luo Jingcheng's problem early on, even the crimes he committed."
“So she ended up committing suicide instead.”
“We have already confirmed that Luo Jingcheng is indeed a congenital azoospermia patient, which is consistent with the previous inference of the suspect, plus the current series of clues, can we issue a warrant for him?”
Xia Shen asked.
"Don't be in such a hurry. We are not sure where Luo Jingcheng is specifically, how he suddenly returned, and what is the meaning of Lu Yue losing a piece of her finger. Call Xiao Bai right away, tell him about this, and ask him to apply for a search warrant from the police to investigate Luo Jingcheng's villa."
"Both sides of the house must be carefully surveyed and not overlooked..."
"Continue to investigate this man, Luo Jingcheng. Qingqing said she remembers that the person who kidnapped him had a mole near his eye. Luo Jingcheng has a friend who is a plastic surgeon, contact him and ask if Luo Jingcheng has had a mole removed by him."
Xu Yingzhi gave instructions to Xia Sen while driving.
"Understood, I'll call Xiaobai first."
Xia Sen picked up his phone and called Bai Yichun. The call was answered in just two seconds.
"How are you guys? Have you arrived?" Bai Yichun asked nervously.
"Not yet, but soon. There's something I need to tell you, hurry and take care of it. Is everyone still there?"
It's already very late now, Xiaosen looked at the time on the computer, it's almost midnight.
"Dr. Xue and Dr. Yuan have gone back temporarily, Qian Hong and Si Lin are still here, Sui Rui said she would accompany her sister, so we stayed together."
"What do you want me to do?"
"I found medical records of Luo Jingcheng receiving treatment abroad. He is indeed a congenital azoospermia patient. Captain Xu said to apply for a search warrant at the police station now, go to Luo Jingcheng's two villas, and conduct a thorough search to see if anything can be discovered."
"Although we found the medical records of Luo Jingcheng, we are still not sure where he is right now. However, my sister said that the person who made her faint was Luo Jingcheng. I think he came back secretly. Also, we have not found Lu Yue's finger."
"I understand, I will go and look for it. We will take care of it right away. Contact me if there's anything else."
Bai Yichun hung up the phone in a hurry, and everyone looked at him nervously.
"I'll go find Officer Jiang first, Qian Hongsilin, you go to the parking lot and wait for me. We need to split up and take action."
As soon as Bai Yichun finished speaking, he was already gone.
"What should I do?" Liu Sirui pointed to herself.
"If you're tired, go back to sleep. If you're worried, stay with me," Qian Hong thought this matter was easy to handle, much simpler than the case at hand.
“Then let me come with you. I can't sleep now, and I'm also really worried,” Liu Sirui reached out and grabbed Liu Silin's hand.
“You go with Qian Hong, I'll go with Xiaobai. Two heads are better than one,” Liu Silin reached out and patted Liu Sirui's hand, “We need to investigate the house where Luo Jingcheng is currently staying and his old house. We need to split up and work separately.”
"Okay, I'll go with you."
As soon as Liu Sirui said that, she immediately went to the parking lot with Qian Hong.
Liu Sirin also followed behind, they were waiting for Bai Yichun to bring the search warrant.
They waited in the parking lot for ten minutes, Bai Yichun came quickly and efficiently took care of the matter without wasting a single moment.
"Take this, let's go..."
Bai Yichun handed a search warrant to Qian Hong, and his own to Liu Silin.
Two teams of people and horses set off immediately towards the two houses of Luo Jingcheng.
