You went on a blind date and presented an A-level wanted criminal as a meeting gift?

Municipal Bureau, Forensic Center.

The brightly lit laboratory was filled with a cold and unique smell, a mixture of formaldehyde and various chemical reagents.

Jiang Tingxue was wearing a pristine white lab coat, goggles, and a mask. Her long, jet-black hair was neatly pinned up at the back of her head, with only a few playful strands hanging down beside her ears.

She was intently operating a gas chromatograph-mass spectrometer worth millions, her expression serious and focused.

The small amount of grayish-white powder sample that Lin Chen brought back from the scene has now been extracted by her using a high-purity solvent and is undergoing the most in-depth component analysis on this sophisticated instrument.

Lin Chen stood beside her, not wearing a lab coat, just watching quietly.

His god-level chemical knowledge and god-level biological expertise allowed him to deduce the molecular structure of a sample in his mind simply by listening to the subtle electrical sounds emitted by the instrument, without even looking at the complex spectra on the screen.

The two were very close, and Lin Chen could even clearly smell the faint scent of shampoo emanating from Jiang Tingxue's hair, mixed with her unique, cool, and alluring body fragrance.

Looking at her focused and beautiful profile, and feeling the rare tranquility between the two of them, Lin Chen's heart stirred slightly.

He suddenly leaned forward and gently kissed her smooth, jade-like cheek.

"Hmm!"

Jiang Tingxue's body stiffened abruptly, as if struck by an electric current.

Her hand paused slightly, and her usually aloof and icy face instantly turned red from her ears to her neck.

She turned her head sharply, her beautiful eyes, hidden behind her goggles, glaring at Lin Chen with a mixture of shyness and annoyance. She lowered her voice, her tone slightly coquettish.

"What...what are you doing! This...this is a laboratory!"

"What happened to the lab?"

A mischievous smile appeared on Lin Chen's face, and his voice was neither too loud nor too soft.

"You're not allowed to kiss in the lab? Besides, you're so beautiful, I couldn't resist."

This straightforward and domineering praise made Jiang Tingxue's heart skip a beat.

She felt her cheeks burning, and her breathing became rapid.

Although she was still complaining, her hand holding the test tube inexplicably gained a bit more strength, and her movements became more steady and precise.

This man always manages to make her feel flustered and yet find it sweet in the most serious situations, using the simplest methods.

"Stop...stop fooling around, the results will be out soon."

Jiang Tingxue dared not look into Lin Chen's eyes again, and quickly turned her head away, pretending to be focused on the data on the screen, but her slightly trembling eyelashes betrayed her inner turmoil.

Lin Chen smiled and stopped teasing her.

He knew that for a cold-on-the-outside-but-warm-on-the-inside academic beauty like Jiang Tingxue, occasional spice things up was the best catalyst.

Time passed second by second amidst the deep hum of the instruments.

Finally, after nearly two hours of complex analysis and data comparison, the final test report slowly emerged from the printer.

Jiang Tingxue took off her goggles, picked up the still-warm report, and after just one glance, her clear, cold eyes were filled with undisguised solemnity and shock.

"Lin Chen, you...you're right."

Her voice trembled with disbelief.

"The final analysis results of the sample pointed to a substance that I had only seen in a top-level, confidential overseas paper—'targeted thermosensitive white phosphorus microcapsules'."

Jiang Tingxue took a deep breath, trying to calm her inner shock, and explained in as professional a tone as possible.

"This is a military-grade chemical weapons material that utilizes gene targeting technology and nano-encapsulation technology."

"It can be programmed to act only on organisms with specific DNA sequences, and its spontaneous combustion temperature and time can be precisely controlled."

"Simply put, the killer could have allowed this chemical poison to lie dormant in the bodies of a hundred people, but only detonate it in the body of a specific target."

"This technology is extremely complex, and it is simply impossible to achieve in the current open scientific research field in China! Only in some unregulated biological laboratories overseas, or... on the dark web black market, is it possible to obtain such high-purity, customizable chemical raw materials."

Jiang Tingxue looked at Lin Chen, her eyes filled with worry.

This opponent was on a completely different level from all the criminals they had encountered before.

He was not just a murderer, but also a mad scientist who possessed technology ahead of his time!

However, Lin Chen showed no fear whatsoever after hearing her words.

Instead, a glint of excitement flashed in his eyes, like a shark that had finally found prey worthy of his all-out effort.

"Dark web black market?"

A cold smile curled at the corners of Lin Chen's lips.

"Looks like it's time to take a good look around that filthy underworld."
