The sequence is too involutional, luckily I am too.

"What, you don't want to?"

Lu Yan raised an eyebrow and said, "Don't the investigators dispatched by the Adjudication Department even have this much autonomy?"

"Shut up!"

Upon hearing Lu Yan directly reveal her identity, Yao Qing's expression changed drastically, and she no longer cared about being angry.

"I can give you the cultivation method, but the sequence information is absolutely out of the question. This is a unique method used by the Investigation Department, and if it is leaked, even I will not be able to escape responsibility."

She paused, then added with a hint of sarcasm, "Besides, without the corresponding potion, even if you know the sequence, you won't be able to awaken it; it'll all be a waste of time."

"Don't worry about that, sister-in-law. I have my own way of handling it."

Lu Yan's tone was calm, showing no sign of backing down.

Yao Qing's eyes flickered, and she subconsciously glanced in the direction of the central villa. Hesitation crossed her brows, and after thinking for a long time, she finally looked up, her expression becoming serious.

"I can give it to you, but I need a promise from you."

She said in a deep voice, "If I face a life-or-death crisis, you must save me once."

"no."

Lu Yan refused without hesitation, saying, "We're not talking business, so there's no reason for me to offer you any additional guarantees."

"you!"

Yao Qing's chest heaved with anger, her eyes brimming with shame and rage.

That bastard with a cement-sealed heart—even though they didn't have any real relationship, he still took advantage of her quite a bit. How could he refuse so readily?

"I don't expect you to live and die with me, just help me once without affecting you."

Yao Qing took a few deep breaths, forcing herself to calm down, and said, "With your status, even Wei Xu would give you face."

My identity?

Fourth Master?

Lu Yan was taken aback upon hearing this, but quickly realized what was going on.

It seems that Yao Qing regarded him as a spy planted in the Black Dog Gang by some force. Perhaps Wei Xu also suspected the same thing, which is why he was so lenient with him.

Indeed, when you're out in the world, your identity is given to you by others.

"In that case, I can agree."

Lu Yan pretended to ponder for a moment and said, "But how can you be sure I will keep my promise?"

Yao Qing rolled her eyes, took out a balance scale pendant from her chest, and gently placed it on the letter on the table.

She then bit her finger, and a drop of bright red blood fell onto the balance scale. The pendant instantly lit up with a mysterious pale blue light, drawing the blood to flow across the paper and outlining a broken pattern.

"This is a marvel of the Judgment Department, number 9110: the Scales of Justice. No one may break a contract made through it."

Yao Qing patiently explained, "Drip your blood onto it, then silently recite the terms of our deal in your mind. Only when both parties agree can the contract be established."

"Is it absolutely necessary to bleed?"

Lu Yan frowned slightly, a hint of wariness flashing in his eyes.

The sequences in this world are incredibly diverse, and it's hard to guarantee that there aren't some special methods that can influence one through blood.

"That's right, if you're not willing, there's no need for us to continue talking."

Yao Qing remained resolute and did not back down in the slightest.

Lu Yan remained silent. Seeing that neither the sequences nor his killing instincts reacted, he bit his finger and pressed it.

The pale red lines immediately spread out, intertwining with the previous blue lines, and finally condensed into a complete balance pattern, with the light becoming even more intense.

"I practice the Starry Night Meditation Method, which I can give you now, but I don't have the breathing technique yet. I promise to get it for you within three days."

"As for the sequence..."

Yao Qing paused, hesitated for a moment, and then said, "The sequence I awakened is called [Detective], exclusive to the Judgment Department. You absolutely cannot reveal it to anyone, or we will all die."

"detective?"

Lu Yan raised an eyebrow. This sequence didn't seem to fit with the Judgment Department at all.

Yao Qing seemed to have anticipated Lu Yan's expression, and said angrily, "Do you want it or not? If not, forget it!"

"Yes! Of course I want it!"

What a joke! How could a sequence that can be monopolized by the Judgment Department be weak?

Seeing this, Yao Qing finally revealed the complete conditions for the detective's awakening.

[Sequence 9 Discovery - Detective]

[Awakening Condition 1: Solve ten cases (Completed)]

[Awakening Condition Two: Using language and psychological suggestion as means to guide the criminal to voluntarily confess to the crime (0/3)]

"I never thought that my years of experience in studying science in my previous life could come in handy here."

Lu Yan was already used to the gifts from his past life, but this one, which guided the criminal to voluntarily confess his crimes...

Lu Yan's gaze unconsciously drifted to the window. At this moment, the talents were still diligently cultivating, showing no signs of slackening because of Lu Yan's departure.

Who would have thought that most of these people were the most vicious criminals in the town?

I feel like this detective series will be completed very quickly...

Just then, new subtitles flashed on the panel:

[Teacher Promotion Requirement 1: Master the three Sequence 9 Awakening Conditions (3/3) - Completed]

Lu Yan was overjoyed and immediately pressed his advantage: "Do you know about the Detective's Sequence 8? Tell me about it too."

The third requirement for promotion in the teacher's career path is to master the awakening conditions of a spiritual sequence 8. It would be ideal if this could be resolved here as well.

"Don't push your luck!"

Yao Qing completely lost her temper, shouting angrily, "I've already taken a huge risk telling you about the Detective Sequence. If I tell you about Sequence 8, I'd rather die than let you get away with this!"

Lu Yan remained silent, simply gazing at her with unwavering determination in his eyes.

Yao Qing almost ground her teeth to powder. This bastard really thinks he can get his hands on me?

After a moment of stalemate, she gritted her teeth and said, "I only know that Sequence 8 is called 'The Listener,' and I know nothing else, so you should give up."

Seeing that Yao Qing was indeed pushed to her limit, Lu Yan stopped pressuring her and changed his request.

"Citizenship? You're not..."

Yao Qing was taken aback when she heard this. Even with Muyun Technology's capabilities, they couldn't get a citizenship.

But soon, she seemed to realize something, and her gaze towards Lu Yan held a hint of sympathy.

Discarding a useful tool after it has served its purpose is a common tactic employed by Mu Yun; Lu Yan is leaving himself a way out.

"I understand, I can help you find a solution."

Suddenly, the letter paper on the table, printed with blood-stained scales, spontaneously combusted without fire, turning into two streams of light that entered the bodies of the two people respectively.

Lu Yan felt a faint golden mark appear deep within his consciousness, as if there was an invisible connection between them, and an inescapable bond.

"During the contract's validity period, neither party can inflict any harm on the other; for now, we are temporarily partners."

Yao Qing breathed a sigh of relief, regaining her usual charming demeanor. She picked up a piece of paper, wrote down the contents of "Starry Night Meditation Method," and handed it to Lu Yan. "Remember to burn it after you finish reading it. I will send the breathing method over as soon as possible."

"it is good."

Lu Yan nodded slightly, his gaze instantly drawn to the meditation method on the paper, completely ignoring Yao Qing beside him.

"snort!"

Yao Qing stomped her foot in anger, but seeing that he didn't react, she could only turn around and leave resentfully.

[Black Iron Starry Night Meditation Method (Beginner): 0%]

The second requirement for teacher promotion is to master three meditation methods and cultivate them to a high level. He has already mastered two of them and is not far from his goal.

On the contrary, the third promotion condition is a bit troublesome.

[Discovering the Detective Advancement Path - Sequence 8 - The Listener]

[Promotion Requirement 1: ???]

[Promotion Requirement Two: ???]

[Promotion Requirement Three: ???]

Although the name of Sequence 8 of the Detective Path is known, the promotion conditions are all unknown.

Clearly, these conditions involve areas he has never even considered.

"Let's figure out a way to awaken the detective first; more sequences mean more paths."

Lu Yan focused his mind and looked at the panel with anticipation.

The detective noticed you were watching and instinctively shrank further into the closet.

Lu Yan: "???"

Wardrobe?

What respectable detective would hide in a closet?
