Seeing that everyone went to find Song Yi, Qiao Guoqiang walked to the merit box of the Zaowang Temple and threw two red soft sister coins into it. Then he looked at Uncle Seven and asked, "Uncle Seven, I want to see the sesame oil money account books of the pilgrims here, is it okay?" ”

"Does it have anything to do with the case?" Uncle Seven asked

Qiao Guoqiang said: "It's just a guess at the moment! ”

Uncle Seven pointed to his hand and took the account book.

"Scan it!" Qiao Guoqiang handed the ledger to KIKO, "For the rest, let's go out and talk about it." ”

Walking out of the Stove King Temple, Qiao Guoqiang watched Billy being called into the car by Lu Guofu. A few minutes later, Billy took out his mobile phone to read the message sent by Qiao Guoqiang, "Staring at Lu Guofu, I found a new clue." ”

Billy replied with an "OK!" ”

In the café, KIKO asked, "Do you want a pilgrim's sesame oil money book, are you looking for a suspect?" ”

"That's right!" Qiao Guoqiang said, "The murderer is very familiar with this place, so he must come often, and he is very religious." The more devout a person is, the more willing he is to donate money to the temple. ”

"There are thousands of people in there!" KIKO looked at the computer screen, "Are there any filters?" ”

"Screen all those with a medical education or work background!" Qiao Guoqiang said.

"Do you suspect the killer was a medical worker?"

"It could be a butcher, a veterinarian, a coroner, or even a cook," Qiao Guoqiang said, "However, the doctor is the closest, after all, the Y-shaped incision, but the technique commonly used by doctors, plus sevoflurane..."

"Got it!" KIKO crackled on the keyboard and two minutes later said, "There were, there are 32!" She looked at Qiao Guoqiang and said, "One of them is Song Yi." ”

Qiao Guoqiang nodded and asked, "How many Chinese are there!" ”

"Twenty-three!"

"Exclude people who aren't in New York!"

"And 15 more!"

"In addition to the Chinese, check their relatives including: parents, siblings, children, stepchildren, adoptive parents, daughters-in-law and sons-in-law, which are the marks of the Chinese!"

KIKO nodded and said, "This will take some time!" ”

After waiting for about five minutes, KIKO said, "There it is!" There are three! One of them and a Chinese woman are husband and wife. ”

"Look at the Chinese woman you mentioned, is she still alive?"

In less than ten seconds, KIKO raised his head, looked at Qiao Guoqiang and said, "A year ago, I died in a car accident. ”

"Male, medical background, family members who died unnaturally, very familiar with Zaowang Temple... These points all match, don't they? "You doubt him?" KIKO asked, "So, what about motivation?" ”

"This thing!" Qiao Guoqiang held his mobile phone, and the symbol was on the screen

"Don't be disappointed!" Qiao Guoqiang took his mobile phone and slapped the symbol: "Tang Ren, he is half right!" ”

"What?" KIKO asks "Half?" ”

"What is half of the symbol?"

"Of course it's 'Fu!' That's it! Qiao Guoqiang looked at KIKO and said, "Beauty, you are from Xiangjiang, don't you look at Lin Zhengying?" ”

"Lin Zhengying?" KIKO suddenly realized, "Maoshan Fu? ”

"That's right!" Qiao Guoqiang held his mobile phone and said, "I have already sent the photo of this talisman to the group of supernatural writers at the starting point, and they will give me the answer soon." ”

"Why do you have a group of writers?" KIKO asked.

"Because I'm also one of the authors..." Qiao Guoqiang said. "Do some part-time work and make some extra money. You know, house prices in the Celestial Empire are going up too fast..."

He used to make money by writing bids at the cost of construction, but after he went to the testing company, he was so busy that he didn't have time to make bids. He had no choice but to be an online writer at the starting point, relying on the metaphysical knowledge of feng shui that he taught himself when he was in college and studying engineering management (correspondence) after graduation to write some supernatural novels to earn manuscript fees, and his monthly manuscript fee income was about more than 2,000 yuan. (The author is a finance major, but I also have a correspondence diploma in engineering management.) ）

"Now, let's go to the Hudson River and see if there is the talisman in the place where the woman died."

Took a car and went down to the Hudson River under the guidance of the navigation.

According to the situation on "Master of Crime", Qiao Guoqiang and KIKO went to the bank of the river where the body was found.

"The time of the crime was between 11 and 1 p.m. on June 27, and the deceased was found at 6 a.m." "According to the information, this is not the first crime scene, and the police have not yet found the real crime scene," KIKO said. ”

Qiao Guoqiang looked around, picked up a rotten wooden board on the ground and opened a few steps away from KIKO, and then said, "Ready to count the seconds."

The speed of the water flow was measured with a wooden plank, and he said that "the speed of the water flow is 0.4 meters per second." Assuming that the deceased was found floating here, the scene of the crime was between 7.2 and 10 kilometers upstream. ”

"Such a long way?" KIKO frowned, "How can I find it?" ”

"Calculate!" Qiao Guoqiang took out a small notebook and wrote a formula on it with a pen: F=2mvωsinφ.

"What is this formula?" KIKO asked.

"Geostrophic deflection force!" "We can't say for sure how long the body had been floating here when it was found, but we can calculate how long he had been floating in the water," Qiao said. He studied liberal arts in high school, served as a geography class representative for two years, and later studied geography when he studied architecture, and was called "the emperor of geography" by acquaintances! ”

Now, he is going to use the method of the Geographical Emperor to calculate the scene of the crime.

"How?" KIKO wondered.

"How much did the deceased weigh?" Qiao Guoqiang reminded after asking: "Use the metric system." ”

"70 kilograms!"

"f=2*70*Earth's angular rotational velocity*sin40.7(New York latitude)"

"The final result is the horizontal offset velocity."

After pressing the calculator a few times and looking at the answer above, Qiao Guoqiang said, "The deceased weighed 70 kilograms, so the lateral acceleration given to him by the geostrophic deflection force was 7.6 cm/s." ”

"The width of the Hudson River in Manhattan is about 1.2 kilometers." Qiao Guoqiang said, "But the width of our position is 1.6 kilometers, which means that the deceased floated for more than 20,000 seconds to get here." The speed of the water is 0.4 meters per second, so we have to go up at least 8.42 kilometers to find the location where she fell into the water! ”

"8.42 km?" KIKO took the map on his phone and looked at it, "It should be in Washington Park"

"It's around there!" Qiao Guoqiang put away the pen and paper, looked at his phone and said, "And it's at the water's edge, coincidentally, there is an abandoned shipyard near Lincoln Center!" (According to the plot of Qin Feng and Tang Ren observing the bridge behind the scene by the river, the abandoned shipyard should be in a place called 'Yanks' north of Manhattan's Van Kland Park, because there is only one bridge on the Hudson River - the George Washington Bridge, and the rest of the way to cross the river is the river tunnel and ferry)
