Rebirth: My Home Has Become a Gathering Place for Young Women with a "Crazy" Spirit

Every contact leaves a trace.

Qin Lang's gaze fell on the transparent tape securing the four corners of the letter paper on the bulletin board.

In his past life, he was a screenwriter for short dramas. To write good crime drama scripts, he not only read many novels about forensic science but also studied trace evidence analysis. And transparent tape happens to be the easiest medium in the world to leave fingerprints.

The surrounding laughter grew increasingly shrill, but Qin Lang remained calm throughout. He said to Huang Ziqiang beside him, "Go to the supermarket over there and buy a small knife, and also a 2B."

Huang Ziqiang was stunned for a moment, wondering what Brother Lang wanted the knife and pencil for at this time, but he still obediently went to do it.

Seeing Qin Lang make a move, the surrounding crowd gradually quieted down, all waiting to see what Qin Lang was going to do.

Less than two minutes later, Huang Ziqiang came running back, holding a small utility knife and a 2B pencil.

Under the expectant gazes of everyone, Qin Lang lowered his eyes and quickly shaved the pencil lead into fine powder with a utility knife, which fell into Huang Ziqiang's palm.

Huang Ziqiang wanted to pull his hand back, but seeing Lang Ge's serious expression, he could only obediently keep it out, letting Qin Lang scrape the pencil lead powder onto his hand.

"That's enough." Qin Lang's lips curled slightly, and a smile appeared in his eyes.

The next second, he grabbed Huang Ziqiang's hand and, "whoosh..." gently blew the pencil lead powder from his palm onto the strips of transparent tape that were securing the letter.

This is the most primitive, effective, and intuitive physical development method.

Moreover, he had read in a book that human fingers secrete oil and sweat, and after contact with tape, these traces would remain on the smooth adhesive surface, and pencil lead powder is most likely to adhere to oil.

In less than three seconds, to everyone's astonishment, a complete and clear outline of a black index finger fingerprint gradually emerged on the originally transparent and seamless tape pasted to the upper left corner of the love letter. The lines were distinct and clearly visible.

Instantly, silence fell over the surroundings. Everyone stared wide-eyed in astonishment at the fingerprints on the tape.

Qin Lang straightened up and shook off Huang Ziqiang's hand. His gaze swept over the fingerprint, and he spoke slowly, his tone calm yet carrying an undeniable certainty: "This is a whorl pattern. Judging from the shape, it's the fingerprint of someone's left index finger."

Everyone held their breath, waiting for Qin Lang to reveal the answer.

"Look here! There's a tiny break in the middle of this fingerprint. It's not a natural pattern; it's from the adhesive residue left by a band-aid."

As soon as Qin Lang finished speaking, he suddenly raised his head, his sharp gaze piercing through the crowd and locking onto a figure who was lowering his head and shrinking his body, trying to sneak away quietly.

The man looked embarrassed, his eyes darting around, trying to sneak away. But as soon as he turned around, a burly figure blocked his way.

After Qin Lang finished using Huang Ziqiang's right hand, he arranged for him to stand behind Feng Chen to block the kid from escaping.

"band-aid."

Outside the crowd, when Xu Han heard the words "band-aid," he immediately thought of someone: "It's Feng Chen. Feng Chen borrowed a band-aid from me yesterday."

"Wow! Has Qin Lang been possessed by Sherlock Holmes?" Ruan Zhihuan looked at Qin Lang in disbelief. This kid is terrifying.

After listening to Qin Lang's analysis, the onlookers roughly understood that it was a person with a band-aid on their left index finger who forged the love letter by imitating his handwriting.

But where can we find this person with the band-aid stuck on their face?

We can't possibly check the fingers of every single one of the more than two thousand students in the school, can we?

However, when they saw Qin Lang's sharp, blade-like gaze seemingly locked onto someone, everyone looked over as well.

Feng Chen's body trembled violently. Almost instinctively, he shoved his left hand, which had a band-aid on it, into his pants pocket.

But it was too late; it was precisely this action that exposed everything.

Actually, the small wound on his left index finger had already healed, but he couldn't bear to throw away the band-aid he had borrowed from Xu Han.

After pasting the fake love letter at 4:30 a.m. today, he put the band-aid back on his finger.

He deliberately removed the tape that had been stuck on after applying the band-aid, thinking he had covered his tracks perfectly. Little did he know, his plan backfired, and Qin Lang discovered the detail.

The surrounding classmates all turned their heads and their eyes fell on Feng Chen. When they saw him hide his left hand in his pocket, everyone had a knowing look on their faces.

The students in Class 3 suddenly realized that it was Feng Chen, their classmate. It was no secret that Feng Chen had a crush on Xu Han, and since Qin Lang had been harassing Xu Han recently, Feng Chen forged this love letter to get revenge on Qin Lang.

There is physical evidence, a motive, and the facts are reasonable.

Seeing Feng Chen's helpless expression, Qin Lang's lips curled into a cold smile. "Little brat, is that all the skill you have? You dare to try and outsmart me?"

Speak with science and convince people with evidence.

Qin Lang exuded an aura that ordinary college students shouldn't have. His voice wasn't loud, but it clearly pierced through the crowd and reached Feng Chen's ears: "Are you going to tear the letter off yourself, or should I take these things to the security office and then give them to Uncle Hat to handle?"

Upon hearing Qin Lang's threat to call the police, Feng Chen's face turned deathly pale, his eyes blazing with madness. He disregarded everything else, frantically pushing through the crowd to the bulletin board. He ripped off the forged love letter, crumpled it into a ball, stuffed it into his mouth, and forced it down his throat.

The paper ball was so big that he almost choked. He rolled his eyes a few times before finally swallowing it.

"It wasn't me! I didn't write it!"

He screamed incoherently, frantically pushing through the crowd, and disappeared without a trace a few seconds later.

The onlookers pointed and whispered in the direction Feng Chen had disappeared, just as they had discussed the love letter earlier.

Qin Lang smiled calmly and walked away.

Huang Ziqiang followed Qin Lang around excitedly, looking at him with admiration and recounting Qin Lang's actions in a vivid and detailed manner.

Walking into the teaching building corridor, they encountered Xu Han and Ruan Zhihuan on their way to class. Xu Han still had that cold, unapproachable expression.

Seeing Qin Lang, Ruan Zhihuan's face lit up with excitement. She leaned closer and said, "Qin Lang, your move just now was absolutely amazing! You were like Conan channeling his magic. Thumbs up!"

"It's nothing, just routine procedure." Qin Lang said calmly as he found a seat in the classroom.

The news that Qin Lang had solved the "forged love letter case" spread like wildfire throughout the campus, and the students were all impressed by Qin Lang's analytical and observational abilities.

In a room in the girls' dormitory, a burly figure was secretly grieving, as if he had just broken up with his girlfriend.

Roommate A: "DunDun, don't be sad, let's go to the library to read some books?"

Dundun: "I don't want to go."

Roommate B: "Shall we go play video games?"

DunDun: "I'm not in the mood, I'm not going."

Roommate C: "Shall we go shopping?"

Dundun: "I don't want to go."

Roommate A: "How about we go eat hot pot?"

DunDun: "Let's go!"
