"Hehehe, Captain Song laughed, this person is getting older and more desperate, how can he tell me the maintenance method, don't you say, Captain Song."

When Song Yuan heard this, a glimmer of light flashed in his eyes, and he said lightly: "Are you sure that you can protect the person you want to protect in this way?" With that, he walked out of the interrogation room.

"Han Tao, check Ning Feiran's information again, be more detailed, and his relatives and friends will check it."

Han Tao began to check the order without a trace of hesitation, and after a while, he sorted out Ning Feiran's interpersonal relationship map and detailed information.

"Ning Feiran, who was admitted to university at the age of sixteen, began to hold a solo exhibition during college, and the success of this exhibition has a lot to do with the support of his grandfather Ning Deyang."

"Han Tao, let's just say what we don't know, we knew these things before."

Song Yuan frowned and looked at the information, seeing the time of disappearance of those eight people, thinking about the time of death determined by the forensic examination, the difference in time was a bit long, and it was really a little difficult to figure it out.

"Don't worry, I just found out something, Ning Feiran's mother died in childbirth, but no one saw her body when she saw her off, and since then, Ning Feiran's father has been in poor health."

Han Tao paused and continued: "The most important thing is that every daughter-in-law that the Ning family can find died of dystocia, and I also found out that the Ning family has a genetic history of heart disease, and the men of the Ning family generally die of sudden heart disease when they are not more than sixty years old, but when it comes to Ning Deyang's father's generation, they have been inexplicably cured, and they all have a long life." ”

"It's also possible that people know that they have this disease, so they cultivate their lives, but their family started from the Qing Dynasty, and each generation almost doesn't live to be sixty, so it's a bit unbelievable that there are two long-lived ones all of a sudden."

"Oh, by the way, I also found out that Ning Deyang still has two elder brothers, but one died because of the war, and the other died because of riding a horse, and the horse fell off a cliff in a frenzy, and the two have one thing in common is that the bodies have not been found." Han Tao added.

"This is strange, it is understandable that the corpse cannot be found during the war years, but it seems that the corpse that fell off the cliff and died can be found and brought back."

"yes, then why can't you find the body?"

Everyone listened to Han Tao's words and began to discuss.

"How long did it take for these two to die?" Song Yuan slammed the document shut and asked with a frown.

"That's what I'm going to say next, the interval between the two of their deaths is one year and six months." After Han Tao finished speaking, he returned to his seat.

"One year and six months, that's about the same time as four of those college students."

"There's definitely something to do with that, but what's the relationship between them."

"Let's go down and collect useful information, and we must solve the case as soon as possible."

"Yes." Everyone saluted and returned to their posts.

And Song Yuan returned to the office and opened the information collected by Han Tao.

Ning Deyang lived to be eighty-six years old, and he was still in good health, but Ning Deyang's father only lived to be seventy-two years old, which is already a long life for the Ning family, but this is far worse than the current Ning Deyang, where did those fresh hearts go, and most of the wives married by the Ning family are illiterate orphan daughters, except for Ning Feiran's mother, why is this?
