"Tell me your thoughts." Bai Youyou nodded.

Xu Xiaoyou did not analyze the photo directly but asked, "Are you certain about the fate of those informants you contacted?"

Bai Youyou paused, then shook her head after careful thought.

"Would those brutal sugar traffickers really let informants who leaked their secrets remain alive?"

"Clearly, the answer is no. You're a Four-winged Investigator, so they wouldn't dare make a move against you directly. To threaten you to stay out of this affair, the only way they can act is against the informants. Whether with human-bomb threats or terrifying photos, they will do everything to make you back down."

Bai Youyou frowned, "I'm a Four-winged Investigator..."

"Have you forgotten the sensational investigator assassination case in Dickwido City? Four-winged Investigator Naxas was murdered by those crazed sugar traffickers, his body hung before Dickwido's city hall, becoming nearly headline news across Cosmos. The association made a big fuss about punishing, but ended up letting a few culprits go with no consequences."

"Of course, compared to Dickwido's quagmire of crime, the local forces in Dragonfly Town wouldn't dare harm you. However, they are willing to intimidate."

"But they haven't, excluding moral concerns, I can't think of another reason for their restraint, except perhaps they killed those informants and buried them somewhere remote, or detained them underground in Dragonfly Town. But this is irrelevant."

"What enables me to make a definitive judgment is their target for Moon Sugar sales."

Xu Xiaoyou placed a photo on the table, pointing at the male corpse's back, showing a cluster of crescent-shaped spots overlapping, varying in shade, like a ghostly face from the abyss sneering.

"Looking at their spirit and appearance, it's clear these deceased are long-time drug addicts. Those cautious, ruthless traffickers wouldn't sell the new Moon Sugar to such dying individuals; they are unstable time bombs, likely to die on the streets. Noticed by investigators or Mountain Crow family's people."

"I reckon you checked the shipping records at the Dragonfly Town port while investigating the origin of this batch of Moon Sugar, finding nothing, correct?"

Bai Youyou was astounded by how the other could deduce so much from tiny details. As the other said, after taking on the Moon Sugar case, she first looked into shipping records at the dock, airport, train station, warehouse, etc., finding nothing suspicious. Reporting protocols strictly require military approval.

If Dragonfly Town's traffickers could manipulate everything, including planting agents in the military, then they wouldn't confine operations solely to Dragonfly Town, nor limit new Moon Sugar distribution to such a small area.

Everything seemed to point to one place.

"Do you think this new Moon Sugar was manufactured in Dragonfly Town?" Bai Youyou asked Xu Xiaoyou.

Xu Xiaoyou remained noncommittal.

With limited chemical knowledge, free from the control of traffickers, yet lacking experience in this area, an image of the mastermind slowly materialized in Bai Youyou's mind, mirroring the person Xu Xiaoyou depicted; most likely a chemistry professor at a university, if not, then someone like a teacher.

"If that's the case…" Bai Youyou formed an idea.

For some reason, the chemistry teacher needed substantial funds urgently, trying forbidden paths, thus embarking on the sugar-making journey.

By narrowing the range further, she could screen all those who worked as chemistry teachers, professors, or consultants in Dragonfly Town, investigate who recently faced significant upheaval, and trace the lines to pinpoint the final target.

"Of course, there's another possibility," Xu Xiaoyou suddenly thought of a relatively bold speculation.

"Youyou, I have a question for you. Based on your observation, how can locusts be effectively eradicated?"

"Insecticide, capturing nets?"

"Breeding," Xu Xiaoyou's lips hinted at an imperceptible curve.

"At one point, Jiangyue City was plagued by locust disasters. As Chichu Heaven's food base, it must annually transport winter grains across all of Chichu Heaven before winter. The locusts caused immeasurable economic loss for Jiangyue City and Chichu Heaven. The Yun Que family never had effective control measures over locusts, trying countless attempts like hiring idle society members to form extermination teams, spraying insecticides to no avail.

"Until a consultant specializing in this area from Cosmic Heavy Industries was invited to Jiangyue City for a field visit. Her team used just one winter to make the rampaging locusts vanish.

"They used genetic editing methods, planting seeds of destruction deep into the locusts' genes. These recessive genes would make locusts lose their breeding ability, becoming apparent within three generations. Every summer, releasing batches of genetically edited locusts, resulting in a widespread extinction due to breeding incapability by winter.

"The day the seeds of destruction break forth signals the extinction of the species."

Bai Youyou suddenly grasped something.

"Those addict insects are the culprits of Moon Sugar's rampant spread, frequenting erotic places, perhaps victims' relatives, constantly drawing more people into their same abyss."

"The chemistry professor possibly aims to purge societal hazards by using new Moon Sugar, eliminating those social threats. You mentioned, after multiple doses of the new Moon Sugar, those addict insects will eventually face suicide from hallucinatory mental states, right?" Xu Xiaoyou said.

"Like the genetic editing consultant, he utilizes his means to eradicate pests. Though I don't approve or agree with his methods, more innocent individuals will be caught up and victims. Yet admittedly, his means are effective, evident in the recently lowered crime rate in Dragonfly Town. More likely, soon enough, these addict insects will be cleaned out, and those traffickers will naturally flee to other places chasing profits."

Xu Xiaoyou said, arms crossed.

Bai Youyou's breaths grew heavier, an eerie chill climbed her spine, sensing the intense hatred within. That chemistry teacher planted seeds of destruction into every 'Genetic Seed,' aiming to obliterate all addict insects in Dragonfly Town, halting Moon Sugar circulation at its roots.

Xu Xiaoyou discreetly watched Bai Youyou. If Bai Youyou decided, Xu Xiaoyou would reveal more information seen on the photos. If Bai Youyou didn't ask, Xu Xiaoyou would remain silent.

Through the photos alone, Xu Xiaoyou had deduced the location and all the site selection methods for the chemistry teacher producing the new Moon Sugar.

Her gaze lingered on the gray-blue dustproof cloth-covered houses lining the street, fingertips tapped lightly on the bar counter.

"Sorry, I… I need some time to think. I'll leave first."

Bai Youyou rushed off, looking preoccupied.

Seeing this, Xu Xiaoyou didn't reveal more information.

The Bai Youyou she knew would never weigh morality against rules, instead decisively choosing the latter. Her twisted personality made her world intolerant of anything that deviates from rules or laws.

It seemed something had indeed changed in Bai Youyou.

As for the 'chemistry teacher,' a vague unease arose in Xu Xiaoyou's heart. At that moment, a privacy number exclusive to the Dark Night Walker called, and upon answering, Kuri's lively, breathy tone came.

"You, it's time to go. I'm already downstairs at the Mint Green Leaf. You didn't forget about our afternoon plan, did you?"
