Si Nian listened carefully and felt that Ji Yuting's analysis made sense.
He asked: "Brother, if he really wants the Ning family, will you help him?"
Ji Yuting's dark eyes were deep and he did not answer this question.
He neither explicitly stated that he would help nor explicitly refused.
After following him for a long time, I naturally understood what he meant and stopped asking questions.

Returning to the National Bureau of Investigation, Ji Yuting immediately asked Si Nian to personally launch an investigation into Mrs. Ning's death.
In the past year, all the servants and bodyguards of the entire Ning family have been interrogated.
After half a day of verification, nothing was found.
Mrs. Ning's autopsy results came out, and she indeed took unknown drugs.
Xi Nian carefully looked at the autopsy results and asked the forensic doctor, "Can you find out what specific drug caused the suffocation death? And the time when the virus was taken."
The forensic doctor shook his head, "No incompletely dissolved liquid was found in Mrs. Ning's body, and the result of unknown drugs was given. This is entirely because of the traces of poisoning on her body. However, if I guess, it should not be a legal drug from abroad."
"As for the time when the virus was taken, it is impossible to determine exactly what medicine was taken and the time when it was taken. Some medicines have an incubation period. It is entirely possible to die after a few days."
It seems to have fallen into silence for years.
In this way, Ning Chengxu cannot be freed from suspicion of the time of committing the crime.
If Ning Chengen insists that it was Ning Chengxu who stole the keys and went to the attic during the dust-washing party, it's hard to tell Ning Chengxu.
He thought about it, returned to Ji Yuting's office, and reported the forensic results to Ji Yuting.
Ji Yuting's expression was serious, "Calling everyone in the Ning family together again for a second wave of cross-examinations. This time I will ask them in person."
Throughout the afternoon, all the servants were taken into the NBI's inquiry room individually in batches.
Ji Yuting: "How has the relationship between Ning Chengxu and Mrs. Ning been like?"
He asked this question to everyone who was sent to the inquiry room.
The servant who usually weeds and sweeps the garden said, "I don't know, I haven't worked in the Ning family for a long time. It was just in the past two years. At that time, the fourth young master was usually busy with secret investigations and didn't go back to the old house often.
, and then it was during this period that he returned to the Ning family, but I knew what kind of relationship he had with his wife. After he came back, he never mentioned his wife, nor did he ask me to visit him. "
A servant who had worked in the old house for fifteen years said, "The relationship is not good. My wife hates the fourth young master. After all, the fourth young master is not her biological child. He was inevitably scolded by his wife several times when he was a child. Maybe it was because of this that he felt resentful.
Will kill my wife!"
Anyone who has stayed in the old house for a long time will say the same thing.
All in all, Ning Chengxu had been bullied by Mrs. Ning when he was young, and later fought for power and was punished by Ning Chengen twice. In addition, he had a history of doing bad things, so they all believed Ning Chengen's inference.
It was Ning Chengxu who poisoned Mrs. Ning.
After a whole afternoon of in-depth questioning, it was almost time to get off work.
All kinds of evidence and witness statements were unfavorable to Ning Chengxu. Ji Yuting was a little annoyed and unconsciously lit a cigarette.
Before he could take a puff, he suddenly remembered Shengge's strict no-smoking order.
After all, I have two cute little babies at home and can't smell the slightest smell of cigarette smoke.
If this was discovered when he went back, he would be dead.
He handed the cigarette to Si Nian and gave it to Si Nian to smoke.
After taking it for a long time, he obediently walked to the corner of the inquiry room and smoked it.
