"Stare at it and answer my question."

Shen Chang'an slightly raised his chin, entering work mode.

"Yes, yes, I will answer truthfully!"

Li Sinan swallowed hard, staring nervously at the statue.

"Have you left Qingzhou District in the past two weeks? Have you been to Shiping District or other districts?"

Shen Chang'an asked.

"Absolutely not! I haven't even left this upscale neighborhood in the past two weeks. I've been staying home every day playing games... oh no, I mean meditating and practicing spiritual cultivation!"

Li Sinan waved his hand repeatedly.

The Bixie statue did not react.

"Have you recently come into contact with any unidentified rogue cultivators? Or... have you heard of any underground cults or associations like 'Black Swan'?"

Shen Chang'an stared intently into his eyes and posed the most crucial question.

Upon hearing the words "black swan," Li Sinan turned pale with fright, as if he had heard of some terrifying monster. He shook his head vigorously, shouting, "Sir! Don't scare me! Even if you gave me ten lives, I wouldn't dare get involved with those ruthless killers! I'm a law-abiding citizen who pays my taxes on time!"

The Bixi statue on the coffee table remained lifeless, its eyes showing no red light.

He then asked a few more questions, but nothing seemed out of the ordinary.

The test was passed, which proves that Li Sinan was not lying.

"Alright."

Shen Chang'an straightened up, picked up the Bixie statue from the coffee table, and put it back in his pocket.

"Thank you for your cooperation. This year's registration and verification are complete. You can continue to deduce the secrets of heaven."

"Alright! Sir, you've worked hard. Let me see you off!"

Seeing that Shen Chang'an was about to leave, Li Sinan felt as if he had been granted a pardon, breathed a long sigh of relief, and followed behind with a big smile, ready to see the guest off.

Shen Chang'an walked to the entrance hall, preparing to push the door open and go out.

Just then, he paused slightly. His keen mental senses seemed to have detected something, and he turned his head with some suspicion, glancing at a tightly closed door on the second floor.

However, that slight fluctuation vanished in an instant, as if it were an illusion.

Shen Chang'an didn't show anything unusual, he just took a deep look in that direction, and then pushed open the door.

"Take care, sir! If you ever need my help again, just let me know!"

Li Sinan stood at the gate, waving his hand with a beaming smile and utmost obsequiousness.

Seeing that Shen Chang'an was about to walk outside.

He let out a long sigh of relief, wiped the cold sweat from his forehead, and reached out to slam the door shut.

Just as the door was about to close, a strong hand suddenly grabbed it and held it shut.

Li Sinan's heart skipped a beat. Before he could react, the heavy solid wood door was slowly pulled open by an irresistible force.

Through the crack in the door, Shen Chang'an revealed half of his cold and stern face. His dark eyes pierced straight into Li Sinan's eyes.

In a blind spot of Li Sinan's sight, Shen Chang'an was quietly holding the Bixie statue in his other hand.

"I suddenly remembered that I forgot to ask two routine questions."

Shen Chang'an stared at him, his voice devoid of any emotion.

"First, have you had any contact with the demon race in the past few days?"

Li Sinan's fawning expression froze instantly, a flicker of panic crossing his eyes. He swallowed hard, stammering a denial: "Demon...demon race? Sir, you must be joking. I wouldn't even dare kill a chicken, how could I dare come into contact with those man-eating monsters..."

In Shen Chang'an's blind spot, the eyes of the Bi'an statue suddenly lit up with a dazzling red light.

Shen Chang'an remained expressionless and immediately posed his second question: "Secondly, what exactly is hidden in the innermost room on the second floor?"

Li Sinan's pupils suddenly contracted, and cold sweat poured down his forehead in an instant, but he still forced out an awkward, dry laugh: "That...that room is just a storage room, filled with scrap metal and props that I usually use for feng shui consultations and rituals..."

The eyes of the Bixie statue once again flashed with a scarlet light, without any doubt.

"You're lying."

Shen Chang'an decisively uttered these three words, then suddenly pushed open the door, strode into the foyer, and reached out to take the other person down.

"Damn it, you're asking for it! You really think I'm afraid of a brat like you!"

Seeing that his scheme had been exposed, Li Sinan dropped the pretense. The meekness on his face was instantly replaced by a ferocious glint.

With a loud shout, the weak spiritual power in Li Sinan's body, which was originally only at the "second realm", suddenly surged wildly like a flood breaking through the dam, directly crossing the threshold and revealing a real third realm cultivation!

"I've endured all these years, even managing to fool your Zhenye Division's investigation, and today I've been outmaneuvered by a little brat like you!" Li Sinan's hands moved rapidly, forming hand seals. A chilling, biting wind instantly swept up from the living room floor, sending trash and talismans flying everywhere. "Don't even mention an ordinary detective like you. Even if Zhao Changfeng from your Qingzhou District came in person, I could still hold my own against him!"

Faced with the menacing Yin winds of the Three Realms, Shen Chang'an's expression remained completely unchanged.

He completely ignored the chilling winds that cut like sharp blades, not even bothering to activate his protective aura, letting the gale make his clothes flutter wildly.

"Whoosh!"

Shen Chang'an's figure passed through the wind wall in an instant, like a ghost.

Li Sinan didn't even see Shen Chang'an's movements clearly. He only felt a blur before his eyes, and a large hand like an iron clamp had already accurately and firmly grabbed his neck!

"Well--!"

Li Sinan's arrogant shouts came to an abrupt halt, his feet were instantly forced off the ground, and he was like a duck with its neck being squeezed.

Shen Chang'an didn't even bother to say a word. He grabbed his neck with one hand, dragged him, and strode towards the stairs to the second floor.

"Let...let go..."

Li Sinan's eyes bulged out, and he gripped Shen Chang'an's wrists tightly with both hands, desperately trying to break free. He frantically mobilized the spiritual power of his proud third realm, attempting to cast a spell to counterattack.

However, he discovered to his dismay that the slightest exertion of his spiritual power would cause the hand gripping his neck to tighten its hold. That terrifying force seemed capable of snapping his cervical vertebrae as easily as crushing a cookie!

Feeling the overwhelming power that left him powerless to resist, Li Sinan's arrogance was instantly swallowed up by endless fear. He dared not have any more thoughts of resistance and could only let Shen Chang'an drag him upstairs like a dead dog.

In fact, just as he was about to leave through the entrance hall, Shen Chang'an's keen spiritual power had already detected a faint trace of demonic energy drifting down from the second floor.

Although the demonic aura was extremely well concealed, so faint that even a fourth-realm lamplighter standing here might not be able to detect it, he was a genuine fifth-realm powerhouse! He trusted his combat intuition and perception abilities, and absolutely did not believe he was experiencing any so-called "illusion." Since there was demonic aura, he would simply expose it!
