Stop pretending, I'm a security guard, a five-star general!

"Damn! Da Mao, you look like a complete idiot, but you're actually quite useful when it counts!"

Liu Damao looked completely bewildered: "Wait, Lao Qin, what are you talking about? I don't understand at all."

"Hey hey hey, come with me, let's talk as we walk."

Qin Yu waved to Liu Damao, signaling him to come over. Then, as they walked towards the Zijing Garden residential area, he recounted the murder case to Liu Damao.

About half an hour later, Qin Yu and his companion arrived at Building 6 of the Zijing Garden residential complex, the very building where the deceased had lived.

Qin Yu's thoughts at this moment were very simple.

If the murderer really did swing over using something like spider silk, then there would definitely be some marks left on the wall outside the victim's room window.

Thinking of this, Qin Yu took out his iPhone 18 Pro Max 1TB Far Peak Blue phone, turned on the camera function, and then zoomed in on the outer wall of the 18th-floor room where the deceased was located.

However, his phone could only zoom in 50 times, and some details were still completely unclear.

Immediately, he turned to look at Liu Damao standing to the side:

"Da Mao, what brand is your phone? How many times can the screen be zoomed in?"

Speaking of this, Liu Damao pulled a mobile phone out of his pocket and proudly introduced it:

"My phone is a Huaxing Mate50 Pro in Wolf Red. It can zoom in on the image by 100 times, and the pixels are still exceptionally clear. It's like the ultimate combination of a microscope and a magnifying glass!"

Upon hearing this, Qin Yu couldn't help but gasp – no, he gasped for breath!

"Wow, Huaxing phones are this awesome!"

"Of course!" Liu Damao said proudly.

"Huaxing, Wolf Warrior, and GNR are known as the three great prides of the Great Xia people!"

(PS: Applause is due here, clap clap clap, haha, I'm going to laugh myself to death sooner or later.)

Then, Qin Yu took Liu Damao's Huaxing Mate50 Pro Wolf Red phone and pointed the screen at the wall outside the 18th floor, carefully looking for anything suspicious.

It must be said that Liu Damao was not bragging.

Despite being magnified a hundred times, the image remained crystal clear; Qin Yu could even see the patterns on the wings of a mosquito that happened to fly by.

Even with such incredibly clear visuals, Qin Yu did manage to find something suspicious.

On the wall less than a few dozen centimeters from the window of the deceased's room, there was an extremely small but deep hole, as if some kind of sharp steel needle had been forcibly inserted.

This could not have been formed naturally; it must have been inserted artificially.

Considering the tiny ligature marks found on the bodies of the deceased, the answer is obvious!

New machine, wow, one more time, hey, drag it!

If he wasn't mistaken, the murderer likely possessed some kind of talent, such as the ability to manipulate fine threads or spider silk.

This allows him to move freely among the city's skyscrapers like Spider-Man, and he can also use thin threads to bind the limbs of his victims and control them to achieve his desired goals.

Thinking of this, a wide smile slowly crept onto Qin Yu's lips.

From today onwards, please call me Edogawa Hata!

After discovering this crucial clue, Qin Yu immediately called Li Wenwen to inform her.

Subsequently, the Night Patrol was also greatly alarmed and began to follow this clue, searching the outer walls of the rooms where each victim died for similar small holes.

And sure enough, their investigation revealed similar tiny holes.

This discovery greatly excited the Night Patrol, who began to expand their search along these small holes to find the killer's trail.

Once you have a sign, everything else will be much easier.
