The reason it's called "one of the collaborators" is because in his past life, the people who schemed against Aunt Qimeng weren't just one. Aside from He Jing, there must have been others working with her.
In his previous life, as a college student, Lin Yu had no ability to investigate everything thoroughly. By the time he gained some life experience, the incident had long become untraceable.
All he knew was that after being deceived, Aunt Qimeng had cried in front of him, saying:
"I trusted He Jing too much, that's why they fooled me. I had no grudges against them—why did they want to harm me?"
Back then, Lin Yu couldn’t uncover the truth.
Now, not only does he intend to investigate everything, but he also wants to prevent it from happening again.
...
[Ding!]
[Dining with two high-ranking sect elders and conversing harmoniously—the host’s status within the sect is bound to rise soon!]
[Reward: 20 spirit stones.]
After having lunch with Chi Qingchi and Mo Shangying, Lin Yu didn’t rush to engage in further conversation with them. There would be plenty of time in the future—as long as the apartment remained, they would stay.
The most pressing matter now was naturally the [Sect Protection Plan]!
In his past life, Aunt Qimeng had taken meticulous care of Lin Yu.
He remembered all of it.
Since Aunt Qimeng didn’t have time for lunch, Lin Yu wouldn’t let her come back to eat leftovers. Before the three of them started their meal, he packed a portion of the food into a thermal container.
After quickly finishing his lunch, he hurried out to Aunt Qimeng’s flower shop to deliver the meal.
The commercial street where the flower shop was located wasn’t far from the apartment.
A leisurely ten-minute walk would get him there.
On this street, aside from Aunt Qimeng’s flower shop, there was also Mao Ruirui’s pet store, as well as the workplaces of his other two roommates—a retail store and a community clinic.
If he ever had free time in the future, visiting his roommates’ shops to chat and complete tasks wouldn’t be a bad idea.
But for today,
everything else had to wait.
Before long,
Lin Yu arrived in front of Aunt Qimeng’s shop—[Starlight Blossoms] Flower Shop!
Through the glass window,
he could see Aunt Qimeng busy at work.
Beads of sweat dotted her forehead, and she wore a purple headband to keep her hair in place.
She always did this when she was busy—it kept her hair from getting damp with sweat, which would take longer to fix later.
Aside from Aunt Qimeng, there was another woman in her thirties inside the shop, helping wrap roses.
The two seemed close, chatting and laughing together.
Lin Yu stepped inside.
"Welcome—Eh? Xiao Yu, what brings you here?"
Chen Qimeng almost mistook Lin Yu for a customer.
When she realized it was him, her face immediately lit up with joy.
Lin Yu raised the thermal container in his hand and said,
"You spent the whole lunch break cooking but didn’t eat yourself, so I had to play delivery guy."
[Ding!]
[Heartwarming gesture—while the acting sect leader was busy managing sect affairs, the host remembered to deliver a meal, earning her deep appreciation!]
[Reward: 20 spirit stones.]
The reward made Lin Yu feel a little guilty.
The food had been prepared by Aunt Qimeng herself—he wasn’t even "borrowing flowers to offer as a gift," just doing the delivery.
Upon seeing Lin Yu,
the woman next to Chen Qimeng leaned in and whispered:
"Qi Meng, is this the college boy you’re raising at home? He’s so handsome!"
"No wonder you keep turning down blind dates when people try to set you up."
"Fresh grass nourishes best, hahaha… You’re so lucky—and you know which kind of 'luck' I mean."
Chen Qimeng’s face instantly turned red to the tips of her ears.
She quickly swatted the woman’s arm and muttered:
"Be serious! I’m Xiao Yu’s aunt—don’t let him hear you."
After the two exchanged a few hushed words,
the woman waved at Lin Yu with an easygoing smile:
"Hey there, handsome! I’m your aunt’s good friend, He Jing."
"Don’t call me 'aunt'—it makes me sound old. Just call me Sister Jing."
[Ding!]
[Danger Alert: The mastermind behind the sect’s greatest crisis, the "Thousand-Faced Fox," has appeared. Host, proceed with caution!]
[Task Linked: Sect Protection Plan.]
So it’s her…
The system even automatically triggered a danger alert.
This wasn’t a bad thing.
From now on,
if he encountered anyone colluding with her, the system would likely issue a warning too.
As long as he kept a close eye on Aunt Qimeng,
the other conspirators would eventually show themselves.
The He Jing before him had shoulder-length hair,
wearing a black off-the-shoulder bodycon dress, her face heavily powdered.
Her fiery red lipstick gave her a somewhat seductive, "respectable woman" vibe.
If he hadn’t already known about the vile schemes hidden beneath her skin,
his first impression might have been fooled by her friendly charm—thinking she and Aunt Qimeng were the closest of friends.
Suppressing his disgust,
Lin Yu adopted the cheerful, carefree demeanor expected of a college boy and said:
"Hello, Sister Jing. Sorry, I didn’t know there was someone else in the shop."
"I only packed enough food for one…"
"How about I go buy something else from the restaurant next door so you and Auntie can eat together?"
[Ding!]
[Brilliant move—the host’s flawless acting successfully lulled the Thousand-Faced Fox into lowering her guard. Remain vigilant while getting close to the enemy and uncover their weaknesses!]
[Reward: 20 spirit stones.]
Rather than acting cold or hostile and making He Jing wary,
playing the role of a clueless college student would make her more confident in making her move…

grated, and just when he finally managed to get into an elite academy, he discovered that he actually had a system, and the way to earn rewards was extremely ridiculous. So for the sake of rewards, he had no choice but to start acting ridiculous as well. Su Cheng: "It's nothing but system quests after all." But later, what confused Su Cheng was that while he was already quite ridiculous, he never expected those serious characters to gradually become ridiculous too. And the way they looked at him became increasingly strange... (This synopsis doesn't do it justice, please read the full story)

and couldn't return to the real world. Finally, I gave up and decided to go with the flow, only to discover that writing a diary could make me stronger. Since no one could read it, Su Luo wrote freely, daring to pen anything and everything. Female Lead #1: "Not bad. This diary helped me steal all the protagonist's opportunities. I just want to get stronger." Female Lead #2: "I don’t care about reaching the peak of the cultivation world. Right now, I just want to enjoy the chaos." Female Lead #3: "What? Everyone around me is a spy? I’m the Joker Demon Lord?" ... It’s so strange. Why is the plot completely off track, yet the ending remains the same? Are you all just messing with me?!
