I discovered a world bug.

The thing was still getting closer, and all four combatants rushed out of the room into the corridor.

The thermal imaging camera was flipped over, and the gun barrel was pointed at the stairwell.

No abnormal heat source was detected.

The report came through the headset, and almost simultaneously, the noise from the stairwell stopped.

That thing seems to have disappeared.

Or, to be more precise, it hid its whereabouts.

There are no more collision sounds, no more rubbing sounds of plastic sheeting.

The entire house was so quiet that only the breathing of the people could be heard—or even their heartbeats.

"Drone".

Qin Lang gave the order in a low voice, and Jin Yue immediately nodded.

Immediately afterwards, a small racing drone took off.

However, the flying machine did not go directly down the stairs. Instead, it flew out of the corridor, circled around into the courtyard, and then followed the trajectory of the "unidentified object" all the way up.

Jin Yue wanted to cut off the other party's escape route.

After all, if "it" is an entity with some kind of physical form, even if it is invisible, then since one must go up the stairs, one must also go down the stairs.

The buzzing of the drone's rotors came through the wall and then gathered in the stairwell.

The noise was reflected and focused by the wall, making it sound particularly harsh.

But in the images it transmitted, the hallway was still... completely empty.

I can't see anything.

It's as if the sounds that just appeared in everyone's ears were just their imagination.

"Target not detected."

Jin Yue frowned and asked Qin Lang in a low voice:

"Could it be an illusion? The Yinshan method?"

"no."

Qin Lang pointed to the detection data on the PDA—just two minutes ago, when the first knock sounded, the alarm system set up in the courtyard clearly indicated the anomaly.

Those voices could not possibly be a collective hallucination; they were real data.

"The data might be fake..."

Liu Xizhu, who was crouching behind Qin Lang, prompted:

"Everything we see may be fake. If the Yinshan Law comes into effect, everything we see now will be fake."

"Even what I'm saying to you right now could be something I've imagined in my head. You're not actually talking to me; it's even possible that I'm still lying in bed..."

"impossible."

Qin Lang pointed to the PDA in his hand.

"The core function of this PDA is to use simple RSA encryption. I just opened the PDA with the key, which is a prime number. You can verify it immediately."

"In a hallucination, I would never be able to accurately construct such a large prime number."

"......science."

Liu Xizhu nodded.

"That's the real thing, but it's... a ghost?"

"Bang!"

As soon as he finished speaking, another dull thud suddenly echoed in the courtyard.

"under!"

Qin Lang reacted immediately. Then, the drone turned around, and the four special forces soldiers holding rifles also stood up at the same time, sticking their gun barrels out from above the stair railing.

"The side of the car!"

The team members refrained from firing, but Jin Yue's drone recklessly crashed into it.

In an instant, the drone seemed to be caught in some kind of swirling airflow.

The blades were instantly twisted by the strong airflow, and the drone tumbled up and down eerily in a very small area.

Jin Yue tried desperately to control the drone, but to no avail.

"air mass!"

He immediately spoke up to warn them.

"That thing is a cloud of air!"

"Is it lethal?"

Qin Lang pressed on with more questions, and after only a second of hesitation, one of the special forces soldiers next to Jin Yue suddenly rushed out.

"I'll give it a try!"

He strode down the stairs, taking advantage of the drone still spinning and swirling in the air, and charged towards the "cloud of air" like a wall.

Before anyone else could even speak up to stop it, the air mass was instantly dispersed.

The drone plummeted downwards, then pulled back up before hitting the ground.

The team members turned to look at Qin Lang, their expressions slightly bewildered.

He felt as if he had simply stumbled into an extremely viscous wind.

There was no "chilling" feeling, no ghostly faces, and no hallucinations.

The gust of wind simply dissipated.

For a moment, he did feel a terrifying sense of suffocation, as if the huge pressure difference was about to suck all the air out of his lungs.

But that was only for a moment.

This thing...

Seems like it's not very useful?!

The team members looked around, and in the blink of an eye, the cloud of air formed in another corner.

"Bang!"

A flowerpot on the kitchen windowsill was knocked over, and the team member rushed over without stopping, but this time, he didn't hit anything.

"Jin Yue, activate the thermal imaging drone!"

"Forget about this thing, arrest them!"

"This is not the Yinshan Method!"

"I'd like to see who the hell is controlling this thing!"

"clear!"

Jin Yue immediately dropped the control stick and rushed to the rooftop with another teammate.

There, two thermal imaging drones, originally intended for mountain search, were already ready. Just seconds later, the drones roared into the air.

The crisis in the courtyard was not over—but whether it could even be considered a crisis was anyone's guess.

After all, apart from exhibiting a certain "frightening" characteristic, that thing did not show any danger.

Even so, Lin Shu quickly returned to her room, took out the peace charms she had just drawn, and distributed them to everyone.

If it was just an abnormal flow of air, then the power of the "stabilizing rule" contained in the amulet should have been able to eliminate it immediately.

With the amulet in hand, the atmosphere in the house instantly relaxed a bit, and at the same time, the drone in the air began to scan the surrounding area without any blind spots.

"Prioritize searching for the highest points we can see."

Chen Zhu said to Qin Lang:

"If I were him, and I used this method to attack, I would definitely choose a location where I could be seen."

"clear."

Qin Lang immediately relayed the instructions to Jin Yue, and Lin Shu subconsciously looked up at the distant mountains.

It was pitch black there, and under the dim starlight, it seemed as if a giant beast was lurking.

Will someone be there, staring back at me?

The thought swirled in my mind for a moment, then...

Lin Shu's hair fluttered.

He felt as if he had been thrown into a vacuum, his lungs were being squeezed so tightly that his breathing stopped abruptly halfway through.

asphyxia!!

So this is what it feels like to be haunted by a vengeful ghost?!

He subconsciously reached into his pocket for the amulet, which was burning hot to the touch. The moment he took it out, the amulet spontaneously combusted in the air.

A strong sense of dizziness struck him instantly, and before his body could react, Huo Qing, who had been standing to the side, had already noticed his abnormality.

"Lin Shu!"

Huo Qing lunged at Lin Shu and shoved him away.

"boom!"

Lin Shu's body slammed heavily against the door, a sharp pain shooting through her, but the feeling of suffocation quickly disappeared.

"Get moving!"

Huo Qing shouted:

"This thing has its eye on you! Move!"
