After dinner, Lin Huang opened the hunter's official website as soon as he returned to the hotel room, and submitted an application to view the location of the four corpses of the Emperor Heart Ring in the background, and then submitted an application to view the call records and usage information of the Emperor Heart Ring.

After doing this, Lin Huang checked the information about the brain food sent by Han Ji again.

Han Ji's information on brain food is described in great detail, much more detailed than the information in the monster book that Mr. Fu came over, and the difference is like a doctoral student's graduation thesis on Earth and an after-school essay for elementary school students. In terms of information content alone, Han Ji's information is more than a thousand times that described in the monster illustrated book.

Lin Huang had just seen the first experiment, and before he could click on the video, he received several messages from the Hunters Association.

[The application for the positioning of the Emperor Heart Ring has been approved, please check the attached content for details. 】

[The call record of the Emperor Heart Ring has been passed, please check the attached content for details. 】

[The information on the use of the Emperor's Heart Ring has been approved, please check the attached content for details. 】

Lin Huang immediately closed the information page of Brain Food and checked the attachments of these messages.

The first is a screenshot of the positioning of the four deceased and the displacement of the coordinates on the day of death.

When Lin Huang opened the location screenshot, he also opened the map of Rossi City, and after some comparison, it was easy to find the final place of death of the four people.

"It's all underground hotel ......," Lin Huang frowned slightly.

The last location of the four deceased's Imperial Heart Rings was in four different underground hotels nearby.

The so-called underground hotel does not refer to the kind of small and dirty hotel with basement rooms, but refers to a special type of hotel that is specially used for dating guns. This type of hotel usually not only has a very tall decoration of the rooms, but also has all kinds of equipment inside, and the fees are quite high.

The reason why many people are willing to come to this kind of hotel is that there is no monitoring equipment, and there is no need to check in, just transfer credits to the transaction chip, and then find an empty room to check in at will. And every room has a back door, so people in the room can pull out at any time.

This type of hotel, which is fully booked almost every night before eleven o'clock, is quite busy.

The owner of the hotel is usually a guy with a relatively good background in the local area, and it is usually difficult to get them to cooperate with the investigation even if something happens.

So when he saw that the four coordinate locations on the map coincided with the underground hotel, Lin Huang couldn't help frowning.

"It's a little troublesome......" Encountering this situation, Lin Huang also had a headache, because the hotel owner would definitely not cooperate with the investigation. Even if they cooperated with the investigation, they did not have any other information records at all except the amount of money they entered, and they could not find anything.

After looking at the itinerary of the day of the death of the four people with an accelerated look, Lin Huang did not find what the four had in common. The only thing they have in common is that all four of them live in the vicinity of the area. There were two people who stayed in the same hotel before they died, and they were both the one that Mr. Fu teleported with him. The other two, one lives in the hotel where Lin Huang is staying now, and the other lives in another high-end hotel nearby.

Lin Huang didn't have a clue, he opened the second attachment.

The attached information is the call history and message record of the four people, all the information is normal, there is no talk to anyone about the date, not even an ambiguous message.

This also made Lin Huang even more puzzled, "How did they get in touch with the murderer? Could it be that the four of them have another Emperor Heart Ring?"

Putting this doubt behind him for the time being, Lin Huang checked the last attachment again.

In this annex, the four deceased's records of the use of various functions of the Emperor Heart Ring on the last day are listed, including when they logged in to what website, when they transferred credits, and even the number of times and when some of the small programs attached to the Emperor Heart Ring were opened.

But there is no more specific information, and I can only see the homepage of the website where four people log in, and I don't know what information I have read. The transfer of credit points can only see information such as the transfer time, and the specific transfer amount cannot be seen. There are also some small programs that only know the name of the program, and the duration of use, but do not see the specific usage information.

However, Lin Huang soon noticed that the four of them had one thing in common, that is, they had all logged in to the same small program before they died.

"What is this 'slightly cool night'? the four people all have this program on their Emperor Heart Rings, and they are almost always on or repeatedly for two hours before they die...... Lin Huang looked up this program with doubts.

"It turned out to be a 'dating software'......" After reading the description of the program, Lin Huang instantly understood what this program was. "So, the murderer should have hooked up with the four deceased people through this program, no wonder the communication page could not find any clues, they did not communicate through the communication page at all. ”

However, Lin Huang encountered another problem, the information provided by the Hunter Association could not see the specific chat content of this program at all, so he had no way of knowing who these people were hooked up with in the program.

Lin Huang was helpless, and replied to the Hunters Association, "Can you provide more detailed information on the use of the Emperor Heart Ring?"

This time, Lin Huang quickly got a reply.

"Sorry, Mr. Ye, we do not have the permission to explore more personal privacy and cannot provide you with more detailed information. ”

Although he had already expected this result, Lin Huang was still a little helpless when he heard the answer.

After closing a few pages, Lin Huang went through the existing information he had obtained.

"The information on the communication page is of little use, although it is possible to determine the location of the death of the four people, but there is little hope of obtaining information about the murderer from the underground hotel. At present, the fastest way to confirm the identity of the murderer is to obtain the chat information of these four people on the 'Cool Night'......"

Lin Huang thought about it, among the people he knew, only Yang Ling could get this information, and he immediately dialed Yang Ling's number without hesitation.

The prompt sounded twice, and Yang Ling connected the communication.

Yang Ling in the video is not as energetic as before this time, but looks full of energy. And I changed into new clothes, and even my hair was taken care of.

"Good evening, my old customer. Yang Ling's mood also looked good, and he waved his hand at Lin Huang and smiled.

"You look good today. Lin Huang smiled at Yang Ling.

"That's because you used to call during the day, and I'm a nocturnal animal, and my spirits only get better from eight o'clock every night. Yang Ling rolled his eyes and explained.

Lin Huang looked at the time, it was almost half past eight in the evening.

"Do you have a friend who wants to fake your identity again?" Yang Ling knew that Lin Huang would not dial his number if he had nothing to do, and it was estimated that there was business coming to his door.

"This time it's something else, I want you to do me a favor. When Lin Huang said this, he kept staring at Yang Ling's reaction, and he was a little worried that Yang Ling would refuse.

"Tell me, what's the matter?" Yang Ling didn't refuse.

"You should know the program 'Cool Night', right?" Lin Huang asked.

"Of course I know, I use it a lot. What, do you want me to introduce you to a few girls?" Hearing the program "The night is slightly cool", Yang Ling immediately squeezed his eyebrows at Lin Huang and said.

"I want you to help me check the chat history of a few people on this app. Lin Huang directly ignored Yang Ling's obscene questioning and said his purpose.

"Peeking at other people's chat records on the dating app, you actually have this kind of hobby?" Tsk ......" The expression on Yang Ling's face became even more obscene.

"I'm looking into a case where all four deceased people had logged in to the app frequently before they died. I suspect the killer is the woman they dated. Lin Huang told the truth.

"Oh...... I know what the case is!That one from Rossi City, how did you run so far?" Yang Ling knew what was going on as soon as he heard it, and apparently he had also seen the news on the hunter's information network.

"Can you help?" Lin Huang asked with a nod.

"It's okay to help, but I refuse to be free...... I want half of the bonus of 3,000 life crystals!" Yang Ling said directly.

"No problem, but I have a condition. From now until the end of this case, I need your help and I can't excuse myself, I can't put forward other strings attached, or ask for more life crystals. Lin Huang also put forward a condition.

"Then it's decided!" Yang Ling also readily agreed.
