The young lady is a detective in a vest

At the critical moment, Dong Hanying is actually quite sensible.

Bai Ziqi felt that sometimes she was not calm enough.

Even Dong Hanying is not as good as...

However, when he thought of this sentence, he smiled wryly and shook his head.

Perhaps, fundamentally, he is not as calm as Dong Hanying.

The two left the crime scene and returned to the College Road Police Station.

Bai Ziqi has been suffering from headaches, struggling to recall the scene of the incident just now.

At this time, Captain Yuan Ju came over.

Bai Ziqi quickly stood up, rushed over, and lay down on Captain Yuanju's desk.

　"Captain, I think the deceased Jiang Jingyun did not commit suicide in Lan's Capital's falling case, but murder. But Lan Zhengping did not cooperate with our investigation."

When Yuan Ju heard this sentence, at the beginning, he was indeed surprised for a moment, and then Yuan Ju became very calm.

He didn't say anything, just kept looking down for information.

It seemed that Bai Ziqi's words were not taken seriously at all.

Bai Ziqi was very entangled in this matter.

Bai Ziqi believed that this was a murder case.

He has always insisted on his own ideas.

He felt that there must be something strange about it.

A living woman, with a radiant face and a pretty face, how could she not think about jumping off the roof of the building?

He couldn't believe it was real at all.

He still felt it had to be a murder.

However, Captain Yuan Ju didn't seem to hear what he said.

Bai Ziqi persisted.

He said to Captain Yuan Ju again: "Captain, I was talking to you, didn't you hear?"

Captain Yuan Ju finally reacted when he heard this sentence.

Captain Yuanju became a little unhappy, looked at Bai Ziqi and said, "Why are you talking to me?! Are you questioning me?"

"Captain, no, I think Lan's Capital—"

Before Bai Ziqi could finish speaking, Yuan Ju said impatiently, "Bai Ziqi, I've said it all, the case of Lan's capital falling from a building is just an ordinary suicide case, you don't need to spend time on this ordinary case. "

"But, Captain, this case is not ordinary!" Bai Zi was still confused.

Yuan Ju spread his hands and said, "Now that the case is closed, what else do you have to say? Are you free? If you are free, help me find a document."

After it was over, Captain Yuan Ju stepped out immediately, pushed Bai Ziqi inside, and asked Bai Ziqi to help him find information.

He wanted to find a criminal record from eight years ago, about a drug trafficking case, but he couldn't find it. There was too much information, and it was disorganized.

He found one head and two big ones.

I went to the reference room just now, but I couldn't find it.

The people in the reference room told Captain Yuan Ju that all the materials about the drug trafficking case eight years ago were not handed over at all, but were placed in Captain Yuan Ju's own desk.

So, Captain Yuan Ju came out again and kept looking.

But at this moment, Bai Ziqi was chattering beside her.

Captain Yuan Ju was also a little irritable.

Bai Ziqi looked down and saw a large pile of materials piled up on the floor, in a mess, with no clue at all.

Bai Ziqi frowned, not in the mood to find any information.

He is still insisting on what he just did.

In fact, the file of the drug trafficking case eight years ago is in the reference room.

Bai Ziqi was still very persistent, and said: "Captain, I think this case of Lan's Capital is really not an ordinary case. The deceased did not commit suicide, but homicide. It is really a murder case."

Captain Yuan Ju shook his head when he heard this, and said, "Bai Ziqi, what do you mean? Do you think we are perfunctory in handling the case?"

"Captain, I didn't mean that, I meant—"

"If you have the ability, you can check it yourself! If you find out, I will count you as capable!"

After finishing speaking, Captain Yuan Ju left with a shake of his hand.

"Bang!"

When Captain Yuan Ju walked to the door, he kicked the door vigorously and said loudly, "Hurry up and find me the information about the drug trafficking case eight years ago!"

"Captain, I'm talking about the case—"

"What case! Classify those materials and submit them to the reference room for archiving! It won't be so troublesome to find any materials in the future!"

"Captain! Lan's Capital——"

"Bai Ziqi, I know you are very idle, you are also young and energetic, you don't know where to put your strength, that's why you cause trouble for nothing!"

After speaking, Captain Yuan Ju left in a hurry.

The captain has a lot of things to do.

But Bai Ziqi was struggling with a closed case.

In this case, even the family of the deceased Jiang Jingyun had agreed to accept the compensation from Lan's Capital.

Because Lan's Capital, in order not to affect the operation of the capital and the image of the company, is willing to pay and spend money to settle this matter.

The family of the deceased Jiang Jingyun also agreed.

So no problem there.

But only Bai Ziqi was still struggling with this matter.

Bai Ziqi sat on the desk, thinking about it.

Thinking of this, Bai Ziqi immediately took a measuring tape and came to the scene of the accident again.

This time, he didn't communicate with people from Lan's Capital.Nor were they discovered.

He measured the height of the first floor of the building, and then calculated the floors, and found that the height of the whole building was 82 meters.

Afterwards, he calculated the falling speed of the deceased according to the formula of free fall, as well as the distance.

But he calculated and calculated, it was one head, two big.

"Jingle Bell--"

While he was working on this case, suddenly, he received a call.

This call was not from someone else, but from Captain Yuan Ju.

Captain Yuan Ju said that there was an urgent mission and Bai Ziqi needed to go back immediately.

Bai Ziqi immediately dropped the case at hand and returned to Xueyuan Road Police Station.

Bai Ziqi thought that Captain Yuan Ju had something very urgent to ask him for.

It turned out that Yuanju was looking for Bai Ziqi because he received a call from Bai Ziqi's father, Bai Guoyuan, the chairman of Baiyu Group, saying that he wanted Bai Ziqi to attend an event for Baiyu Group.

Thus, Bai Ziqi came to the exhibition hall of Jianghe University.

During the exhibition, Bai Ziqi was still thinking about the case just now, that's why she made Zhen happy to count it as free fall.

Zhen Xingxin really calculated the result.

After receiving this result, Bai Ziqi finally understood.

The deceased Jiang Jingyun definitely did not commit suicide, but was pushed out.

Otherwise, the result is not like this.

Bai Ziqi carefully looked at the formula and result of the free fall calculation that Zhen Xingxin had calculated, and stood up excitedly.

Lanshi Capital Building is 82 meters high.

According to the formula of free fall, the vertical displacement is obtained, and the time of falling is calculated to be about 4 seconds.

Then according to the formula of the parabola, the horizontal displacement is about 5.4 meters, and the horizontal initial velocity is calculated to be about 4.8 kilometers per hour.

This is the speed of an adult jogging.

Explain what? !

Excitement and agitation were like a flood breaking a dike, flooding out from Bai Ziqi's heart in a mighty, rushing manner, and he could no longer hide his elegance.

Bai Ziqi jumped three feet high, her heart was full of joy, and she couldn't help shaking her hands and cheering: "Oh...it's the same as my reasoning!"
