Bai Chi was inexplicably called downstairs by the twins, saying that he had any gifts to give... Everyone at S.C.I. also followed him curiously. He saw a cute little car parked at the door of the police station - a yellow "golden scarab". There were also a few round rogue rabbits on the door~~

After staring at the car for a long time, Bai Chi asked the twins blankly: "This~~ I'm for me?"

"Yes~~" the twins nodded, "You have earned so much money for us, this is a gift for you~~"

Xiao Baichi had a bitter face. If it weren't, it wasn't. The other S.C.I. people couldn't stand up straight. Bai Yutang looked at the twins in admiration: "You two are so good~~ He drove out this kind of car and the image of the police was completely destroyed."

"I don't like this~~~" Bai Chi said in a low voice.

The twins looked at each other and asked Bai Chi, "What style do you like? We picked it all over and over and over again, and thought it matched the most with you~~~~"

Bai Chi wrinkled his nose, looked around, and suddenly pointed to an oversized black jeep driving from a distance and said, "I like that style~ large one, and it's very masculine."

"Puff~~~" no matter how everyone heard it, the words "maleness" were spoken from Bai Chi, which was really funny!

Zhan Zhao suddenly patted Bai Yutang, and his eyes signaled him to look at the coming jeep.

The car stopped not far in front of everyone, the car door opened, and a person jumped out, with a cast on his left hand - Zhao Zhen.

Bai Chi had already run over happily, of course not for Zhao Zhen, but for Lisbon in the back seat of the car~~

Bai Yutang and Zhan Zhao looked at each other and walked towards Zhao Zhen at the same time.

"What are you asking for me?" Zhao Zhen asked Bai Chi.

Bai Chi rubbed Lisbon's head, "It's not me looking for you... it's them." As he said that, he pointed to Bai Yutang and Zhan Zhao who were walking towards him.

Zhan Zhao just asked Bai Chi to send a text message to Zhao Zhen and asked him to come to the police station immediately~ I didn't expect that he would really come so soon.

Zhao Zhen looked at the two people standing in front of him and shrugged weakly: "I know what you are doubting... If you want me to help you, I will give me evidence!"

Bai Yutang smiled: "If you can't come up with evidence, you have to protect the murderer against your conscience?!"

Zhao Zhen smiled bitterly, "If you are me, what do you do?"

Bai Yutang sneered, "I said it ten years ago!"

"..." Zhao Zhen was slightly surprised and then remained silent.

Seeing that the two of them were a little nervous, Zhan Zhao turned his face and winked at Bai Yutang, indicating that he should not be angry.

Turning his face away, Bai Yutang pulled Bai Chi with one hand and retreated a few steps away, allowing Zhan Zhao and Zhao Zhen to chat alone.

"Yutang is such a person." Zhan Zhao smiled at Zhao Zhen, "like a knife."

Zhao Zhen glanced at Zhan Zhao and shook his head, "It's okay, in comparison, you have a needle hidden in the cotton, which is even more unbearable."

Zhan Zhao laughed instead of anger: "You know I have evidence~ Bai Chi!"

Zhao Zhen's face changed slightly: "That is difficult to use as evidence, it can only be used as a basis for your doubts!"

"Yes!" Zhan Zhao nodded, "That's why you need to cooperate."

"I refuse." Zhao Zhen wanted to call Lisbon back, but Zhan Zhao said coldly, "Do you know he has lost control?"

"……What's the meaning?"

"Sun Qian's death means you are no longer binding on him." Zhan Zhao looked ahead with his eyes, as if he was talking to himself, "He will kill people soon~ As long as you leave his vision for more than a day, he will be unable to hold back... There will be another Sun Qian~~"

Zhao Zhen's face turned pale, and he looked at Zhan Zhao and asked, "What does it mean to leave for a day...?"

Zhan Zhao stared at Zhao Zhen for a moment and asked coldly: "No, you haven't seen him for a day~~"

Zhao Zhen hesitated, but finally nodded.

Zhan Zhao's expression immediately became serious: "It means that you either help us catch him immediately, or wait for the second child's body to be found.

Zhao Zhen pondered for a while, opened the car door, and took off something similar to a navigation device.

Zhan Zhao winked at Bai Yutang, and Bai Yutang walked up with everyone from S.C.I.

"Is this a satellite tracker?" exclaimed the Ding twins, who are very familiar with unconventional electronic devices.

Zhao Zhen nodded, "I just bought it recently. In order to avoid him doing anything randomly, I put it on him when he didn't notice it.

He pressed the button and quickly searched for the target. The clear location showed that it was the cemetery in S City.

"Pa~~" sound came, and everyone turned around and saw that all the documents in Lu Fang's hand fell to the ground, and their eyes widened in horror.

"What's wrong?" Everyone had a bad premonition.

"Lu...Lu Zhen..." Lu Fang's voice trembled, "Lu Zhen made an appointment with a few children today to visit Sun Qian's grave..."

"Go to the cemetery now!" Bai Yutang ordered and rushed towards his car with Zhan Zhao, and Lu Fang followed closely; Zhao Zhen jumped into the car and drove Lisbon and Bai Chi... together, he rushed to the cemetery of S City.

As soon as I arrived at the top of the cemetery, I heard the screams of children... In an open space at the foot of the mountain, five or six children sat back to back together, and a hunched figure was wandering around them.

Bai Yutang had sharp eyes and saw the man cutting his wrist with a sharp knife, drawing pictures around the children with blood scattered on the ground.

Some of the children cried and screamed, and their hands were tied behind them, but no one seemed to be injured.

One of them looked up and saw the people coming. He quickly shook his head at Bai Yutang running in front, looking at the man's waist...

The child who was looking at him was Lu Zhen. Everyone followed his sight and saw a gun in the man's pocket.

Bai Yutang signaled everyone to separate. At this time, the man had already noticed the arrival of everyone. He laughed a few times, took out his gun, and pointed it at the children.

Zhan Zhao took a step forward and said to him: "Stop resisting - Mr. Butler."

Standing in front of everyone was a thin old man, talking about the old housekeeper of Zhao Zhen’s family.

"What's the name?" Bai Yutang asked.

"...Zhao Meng..." The housekeeper replied without any warmth, turned to look at Zhao Zhen standing aside, and smiled: "Young Master, I have raised you for twenty years~~ Are you betraying me to the police like this?"

Zhao Zhen looked at the butler and the frightened children around him. After a long time, he said, "Submit yourself~"

"Haha~~" Zhao Meng smiled without saying a word, looking at Zhan Zhao and Bai Yutang, "You are lucky. I was betrayed, otherwise you will never find it to me in your life."

Zhan Zhao sneered: "Don't be proud, Zhao Zhen just helped us find you~ As for the real murderer, we have known for a long time."

"What?" Zhao Meng looked suspicious, "How did you find it?"

"At the beginning, we made a big mistake in the portrait of you~" Zhan Zhao said slowly, "We were confused by the intertwined cases and felt that the murderer's behavior was an evolution, so we never doubted you... But when the case was cleared, we realized that in fact, it was not evolution, but a degeneration."

"What?!" Zhao Meng's face changed color, "Degenerate?!"

"That's right!" Zhan Zhao sneered, "The evolution of a serial killer means that his murderous behavior has begun to be selective, with some of his own 'philosophical principles' in it. Such killers are generally at the peak of their physiology. Degeneration is manifested as randomness in choosing objects, and committing crimes is becoming easier and easier, because the killer's ability is declining - you are old!"

Seeing a trace of anger flashing in Zhao Meng's eyes, Zhan Zhao smiled again: "Ten years are nothing for people under the age of fifty, but it is not the case for people over the age of fifty. Ten years ago, when you were in your fifties, you could choose the person you want to kill at will, and ten years later, when you are nearly seventy, you can't kill anyone except children. In addition, you have sufficient conditions to contact and understand the magic circle map..."

"And~~" Bai Yutang said, "According to our investigation, you have been staying in China. Ten years ago, because of the passing of Zhao Zhen's parents, you suddenly went abroad to continue to take care of his daily life - excluding all the impossible, the one that is left behind is true no matter how ridiculous it is!"

"Then, you made another serious mistake!" Zhan Zhao said, "You shouldn't have attacked Bai Chi!"

...Zhao Meng stared at the two of them: "What do you say?!"

Zhan Zhao said: "Because I have doubts about you, I thought, why should I kill Bai Chi? He should know something! At present, everyone is investigating this case and is very sensitive to clues, but he has no special discoveries. In other words, it was in the past! He discovered clues in a boring state~~ When he met again, you found that Bai Chi had a good memory, so he thought he was a threat! So I asked him some details about ten years ago - guess what I asked?!"

Zhao Meng smiled: "When I was drawing the magic circle, Lisbon was having fun and disturbing me. That day, it lay on the magic circle I just drew, and there was an undry pattern printed on it. Later he ran away. I chased it to the library and found that the child was playing with Lisbon in his arms, and the young master was also..."

Bai Chi shook his head blankly: "I...I don't remember this anymore~~"

Zhao Meng was stunned. Seeing Zhan Zhao's slightly cunning smile on his face, he gritted his teeth: "You are playing tricks on me... little devil..."

"Why?" Zhao Zhen interrupted him, "Why do you want to kill someone?"

Zhao Meng looked at Zhao Zhen and smiled a little crazy: "Because... after Young Master Jue left, his life was really boring~~"

Zhan Zhaohe Bai Yutang was stunned - Young Master Jue~~

"I have always taken care of Young Master Jue." Zhao Meng smiled, "I watched him grow up. He is a genius... But he was captured and locked up like this. Then, when I was bored, I began to study the notes he left behind and found the magic circle map~ It was really interesting~~"

Zhan Zhao and Bai Yutang looked at each other. Zhao Meng was so close to Zhao Jue, and it was very likely that he knew the truth about what happened back then.

"Then I started killing people, killing a lot, but life is still boring..." While saying, looking at Zhao Zhen, "Until you grow up, you and Young Master Jue are becoming more and more like each other~ I found the joy of life, so I tried my best to train you to be him, but your father discovered my intentions and took you away from me~ Then..." Zhao Meng suddenly smiled a little gloomy, "God has eyes, they had a car accident~ I raised you rightfully~ In the ten years abroad, cultivating you is more interesting than killing people~ But..." Zhao Meng's face appeared again, "The older you are, the less like him, or, sometimes, sometimes not like him~ Then, the interest in killing has the upper hand again! Especially when someone uses clumsy techniques to imitate me for committing crimes..." The following text was replaced by Zhao Meng's old laughter.

Everyone stared at the old man who was already in twilight in horror, as if his shriveled body had no meaning of existence to him, and he was just a complete ghost~~

"Put down the gun!" Zhao Zhen suddenly said, he raised his chin gently and looked at Zhao Meng with a smile~~

Zhao Meng was almost stunned: "…Jue…”

Zhan Zhao and Bai Yutang were secretly shocked. Zhao Zhen looked so similar to Zhao Jue.

"I'll let you put down your gun and come here!" Zhao Zhen repeated.

It seemed that there was some kind of magic. Zhao Meng squatted down obediently, trying to put down the gun in his hand, just as the gun was about to land. When Bai Yutang was about to go up and handcuffed him, a chuckle suddenly came from the distance~~

Everyone was attracted by the laughter. When they turned around, they saw a person standing on the hillside in the distance - Zhao Jue.

He stood in the backlight, staring at Zhao Meng with a look similar to disagreement, and smiled slightly...

"Ah..." Zhao Meng suddenly shouted, like a possessive, raised his gun again and pointed it at the children...

Gunshots resounded through the sky ~~

Immediately afterwards, the screams of the children...

Zhao Meng's head was shot several times by Bai Yutang - blood splattered everywhere, and the police rushed forward to rescue the child.

On the opposite hillside, Zhao Jue disappeared. Zhan Zhao ran over without saying a word, and Bai Yutang hurriedly followed: "Maoer, wait~~~"

Under the hillside, Zhao Jue walked forward slowly, suddenly, stopped. He looked at a car parked in front of him in surprise. The door opened and a middle-aged man in a suit and tie walked out. He unexpectedly looked very young, but his face was cold and there was no expression. He looked a little mature with a similar face to Zhan Zhao.
