At two o'clock in the middle of the night, Zhao Yu walked to the office window. Looking through the clean glass, you could see the empty streets and deserted alleys.

Although he had not gone outside, Zhao Yu could still feel a stuffy atmosphere, which was spreading on the streets and alleys, as if he was about to hold up another heavy rain...

After watching the street scene, he looked at the system interface in his mind again.

Although he was a little proud, Zhao Yu still felt a little regretful, because if he had made the hexagram the day before yesterday, he might be preparing for a bumper harvest now!

The dazzling array of props is put aside for the time being. He now has more than 80,000 points. If the Ghost King case is handled well this time, maybe it will reach 100,000 points after completion, and the system will be upgraded to a higher level!

Now, he could only watch the system interface without any movement and pay for his stubbornness!

"After that, this should be the most legendary case you have solved, right?" Cui Lizhu got an ice cream from somewhere. While licking the cool cream, she sighed at Zhao Yu, "Have you tried too hard?

"You've actually discovered the truth about the Tao Yulan case 66 years ago! Boss," Cui Lizhu first licked the cream on her finger, and then gave Zhao Yu a thumbs up, "You're really about to become a god. I now doubt that in this world, are there any cases you can't solve?"

"Low-key, low-key..." Zhao Yu said as always, "It seems that there is no case that this detective cannot solve yet? No wonder, Meow Meow advises me to solve the unsolved historical case!"

"Tsk... it's coming again..." Cui Lizhu pouted her mouth, and her sense of respect for Zhao Yu disappeared without a trace.

"Boss," Ran Tao asked, "Since Yang Qinchen has already found the truth about 66 years ago, then... he said nothing, how did Tao Yulan die?

"Why did he suddenly die before he was arrested by the police?

Hearing this, Zhao Yu shook his head slightly: "Yang Qinchen said that he didn't know what was going on, but he could probably guess that it was definitely not a police problem. After all, the case has not been tried clearly yet!

"For such a sensational case, of course the police don't want him to die so soon?

"According to Yang Qinchen's speculation, he suspected... it was more likely that Tao Yulan would commit suicide due to crime!"

"Oh? Suicide for fear of guilt?" Cui Lizhu and Ran Tao spoke at the same time.

"Yes," Zhao Yu said, "Yang Qinchen said that when he and Tao Yulan committed the case of Ghost King, they used a local viper venom in western Sichuan. This snake venom is very venomous. After injection, it can cause people to lose any reaction within five minutes and stop their heartbeat within ten minutes!

"At that time, they had completed five Ghost King cases. It can be said that Tao Yulan had already finished her wish and had no worries anymore. She knew that she would die after being arrested. She was afraid of implicating Yang Qinchen, so she simply chose to commit suicide, which left the world with a ghost king mystery that lasted for more than half a century!"

"Wow!" Cui Lizhu couldn't help but exclaim, "If... if... if it weren't for Yang Jianen and Yang Zimei's re-use of the same trick, if Yang Qinchen was not alive, I'm afraid... no one would know this secret again!?"

"Hmph, who knows!" Zhao Yu shook his head and sighed, "There are causes and effects in the world. Perhaps there is really a certainty in the dark, right?"

"It's pretty ridiculous. Are you in the ghost world?" Cui Lizhu took a big mouthful of ice cream and asked Zhao Yu, "By the way, since Yang Qinchen admitted that he was Tao Yulan's accomplice, then... what should we do with his crime?"

Hearing Cui Lizhu's question, Zhao Yu shook his head indifferently, saying that he didn't know.

"It should not be prosecuted, and it is even difficult to file a case!" Zeng Ke suddenly gave the answer from a distance, "According to the provisions of our country's Criminal Law, if criminal crimes that have been prosecuted for more than 20 years need to be prosecuted, they must be reported to the Supreme Procuratorate for approval!

"In the Tao Yulan case, the case has been tried, and Yang Qinchen is not a fugitive. In addition, since the date of the crime, the suspect has not committed any continuous crimes or other criminal acts.

"If we consider his current age and unstable mental state, so...even if Yang Qinchen has pleaded guilty, this case will be the only way..."

"Okay, it's almost the same as I expected!" Cui Lizhu shrugged, "Anyway, this old man is old and plagued by illness, and has no ability to serve his sentence. He gave us a truth before his death, which is considered a good thing!"

"No..." Zhao Yu said, "He has done more than one good thing! If it weren't for him, I would have no choice but to deal with Yang Zimei!"

"Ah? No?" Cui Lizhu was surprised, "No... did the old man testify against his son and granddaughter with red mouth and white teeth? Could it be...you..."

"I just used a montage trick..." Zhao Yu stood tall, deliberately making his figure taller, and then said, "Actually... from the beginning, I had targeted this old man!

"But I just want to check the absent certificates of Yang Jianen and his daughter through him, but I didn't expect that so many unexpected situations would be found...

"Although the old man is often confused and is in a coma for five days a week, his mind is not confused and he remembers everything clearly, but...

"Often Yang Jianen only takes care of his physiological needs, but ignores his spiritual feelings, so... In Yang Jianen and Yang Zimei's view, the old man is no different from the vegetative man, and it cannot hinder their major events!

"But, after the operation, they needed to live in Qi Hao's house for a long time and had no time to take care of the elderly, so they sent the elderly to the hospital and hired a nurse to take care of them!

"I think if Yang Jianen and his daughter made any mistakes, then the old man was undoubtedly their biggest mistake!

"I went to the hospital. At first I thought the old man was a vegetable and I got nothing from him, but I didn't expect..." Zhao Yu shook his head, "I don't know if the doctor used the right medicine or the auspicious person had a natural appearance. When I went there, the old man just woke up!

"Then, I just asked him the Ghost King case straight to the point, but in the end, I got such a big surprise. To be honest, at that time... I was also very scared!

"I had expected it before that the old man might be Yang Qinchen, but unexpectedly, he was still half a ghost king killer and personally participated in the Tao Yulan case!

"To be honest, I still feel like watching a martial arts movie..."

Zhao Yu stroked his heart and continued: "I saw that the old man had completely opened his heart, so I had an idea and told him that his son Yang Jianen and granddaughter Yang Zimei were secretly planning to implement the Ghost King case, wanting to pay tribute to their ancestor Tao Yulan and kill several enemies. Fortunately, our police stopped him in time, otherwise, it would have been a big mistake...

"It's because I said this that the old man provided the confession on my phone. Didn't you see it... Did I edit the video?"

"Oh...it's actually the case!" Cui Lizhu grinned, her expression looking very unnatural.

"I know, it's not good to do this, but..." Zhao Yu admitted, "But if I say the established facts, I'm afraid... the old man can't tell the truth...

"I can see that this old man is not a fuel-efficient lamp. He can maintain his incognito for 66 years and has certain strength!"

"But..." Cui Lizhu suddenly thought of something, "Don't forget that Yang Zimei hasn't really bowed her head to confess yet! What if..."

"I still say the same thing, it's true and false. If you have dates or not, you will beat it for a long time!

"If Yang Zimei really did not participate in the Ghost King case..." Zhao Yu said frankly, "Then no matter how clever the skills we use, she would never be able to plead guilty!

"But if she is the murderer, then..."
