While they were discussing this matter.

Meanwhile, the door to 301 opened.

That young man named Zhang Yao, with his rather good-looking features, walked out from inside.

In his hand, he held four small bags.

He first went to the door of 302, continuously pressing the doorbell and knocking.

But no one opened the door for him.

He then turned around and went to the door of 303.

At the door of 303, he rang the doorbell.

"Hello, I'm the new resident living in 301."

The door did not open.

Immediately after, Zhang Yao rang the doorbell again.

"Hello! Can you open the door? I need to talk to you!"

Seeing the door in front of him remain completely motionless, Zhang Yao felt puzzled. Could it be that he was the only one living on this floor?

Inside the room.

The two sisters, Qin Yi and Qin Kelian, were lounging coolly on the sofa.

Each leaning their head against one side.

They were using their phones to play a game.

The game they were playing was a recently popular one called Delta.

Just as this round finished, the sound of a doorbell and shouting came from outside the door.

"Sis, should we open the door?"

Qin Kelian, holding her phone with both hands, looked at her sister across from her.

From her perspective, she could see her sister's pair of snow-white long legs, which were extremely alluring.

"No."

"Sakawa is already dead, and we no longer need to make canned goods and other food."

"So, no matter who is outside, it's fine as long as it's not Jiang Ran."

"Okay, then, sister, let's play another round!"

After the two sisters finished discussing whether or not to open the door, they continued playing their game.

Outside the door, Zhang Yao thought 303 was truly empty.

So he went to knock on 304's door. This one, he was sure, definitely had someone inside.

Thus, he knocked on the door.

Jiang Ran was still in the living room watching TV at this moment.

He was watching a Western horror film.

Hearing someone knocking.

He glanced over.

Stood up and went to open the door. 𝑓𝘳𝘦𝑒𝑤𝑒𝘣𝘯ℴ𝘷𝘦𝓁.𝑐𝑜𝑚

After opening the door and seeing it was a stranger, he asked, "Who are you? Why are you knocking on my door?"

Upon seeing Jiang Ran, Zhang Yao first looked him up and down.

Hmm, indeed quite handsome, not worse than himself.

No wonder that Hong Nan could take a liking to him.

Of course, the main reason she could take a liking to Jiang Ran and not him, Zhang Yao knew, was because Jiang Ran was probably a lab rat.

"I'm Zhang Yao, the new resident living in 301. I wanted to get to know my neighbors."

Zhang Yao smiled very politely, simultaneously handing one of the small bags in his hand to Jiang Ran.

Taking the small bag, Jiang Ran said, "My name is Jiang Ran. Nice to meet you too."

Zhang Yao then said, "By the way, Jiang Ran, is it just the two of us living on this floor?"

Jiang Ran said, "I don't know. I just moved in recently too."

Zhang Yao: "I see."

"Well, that's all then. You go ahead with what you were doing."

Jiang Ran nodded, then closed the door.

After closing the door, he opened the small bag and found it was full of candies.

Hard candies, soft candies, and chocolate, a variety of them.

Like the wedding candies given out at someone else's wedding.

However, he didn't eat a single one, directly tossing them into the trash bin.

"If I ate candy given by someone who just triggered a +7 danger warning, that would be the real problem."

Outside 304.

Zhang Yao smacked his lips.

"A lab rat. If I kill him, can I gain more privileges and information?"

"Are there other lab rats in this apartment?"

Zhang Yao and Hong Nan arrived at the apartment around the same time.

Apart from the basic rules they had grasped.

They didn't even attend this welcome party because it was held before they arrived.

Naturally, they also didn't know who the so-called lab rats were this round, or how many there were.

Let alone know about the lab rats that existed before.

"Hmm, should I kill this lab rat named Jiang Ran first, or should I observe the other lab rats a bit more?"

Just as Zhang Yao was walking towards 301, suddenly, the door to 302 ahead opened.

"What the... so 302 has someone after all?!"

Zhang Yao kept walking forward, but the next second, his footsteps abruptly stopped.

Outside the open door of 302.

A yellow-black arm reached out and grabbed the door.

Immediately following it was a human head.

The face of that person's head was initially pointed towards the ground.

But later, it slowly turned, rotating towards Zhang Yao's side.

Staring directly and fixedly at Zhang Yao.

Zhang Yao didn't even notice himself unconsciously swallowing a mouthful of saliva.

Because his current attention was completely focused on the head that had emerged from 302.

The face of that head, those eyes, were completely crimson.

Countless blood vessels formed a dense, web-like pattern of red spiderwebs, completely covering the whites of both eyes.

The appearance was utterly horrifying.

Of course, what was even more horrifying was that the person's forehead seemed to have suffered a severe injury. Blood from the forehead covered his entire face.

Two words described the whole face: ferocious.

"Hiss..."

Zhang Yao drew in a sharp, cold breath.

He couldn't control himself from stepping backward.

But the person who had appeared from 302 lunged forward.

His entire body was now out, no longer blocked by the door.

Zhang Yao stared at the kitchen knife in this person's right hand.

A sense of foreboding rose from the depths of his heart.

Immediately, he turned and ran.

From the corner of his eye, he saw the man who had emerged from 302 starting to chase after him with large strides.

"I haven't even started killing anyone, and I'm already being targeted by someone else?"

Zhang Yao's heart was pounding very fast.

He truly hadn't anticipated this situation.

Just as he had run forward for about ten or so meters, suddenly, a furious roar came from behind him, followed immediately by *thump thump thump* sounds.

Zhang Yao stopped running, turned his head back, and saw a scene that utterly astonished him.

He saw the man who had emerged from 302 frantically bashing his own head against the white wall.

While bashing, he also shouted, "Stop! Stop! You can't kill anymore! You really can't kill anymore!"

His shouting voice was extremely mournful and wailing, as if he were fighting against something.

Seeing this, Zhang Yao's pupils contracted.

It wasn't over.

That man, after bashing his head against the wall, actually started using the kitchen knife in his hand, using its sharp, snow-white blade, to forcefully slash his left arm over and over again.

Each slash caused flesh to split open.

Gushing blood continuously flowed from his arm, dripping onto the ground.

This operation truly left Zhang Yao staring dumbfounded. At the same time, Zhang Yao's heart inexplicably felt shock and terror.

This man, while using the knife to slash his arm, had an expression on his face that crazily shifted, laughing one moment, crying the next. When laughing, it was all kinds of laughter—miserable laughter, hearty laughter. When crying, it was also sorrowful crying, mournful wailing.

If the person before him was a mental patient, Zhang Yao wouldn't doubt it in the slightest. In fact, Zhang Yao even believed the person opposite was an absolutely super, invincible mental patient.

Zhang Yao just watched the other person self-harm, self-harming for several minutes. Suddenly, the other person stopped using the knife to slash his hand, and his face and everything else returned to normal.

This "normal" was only in comparison to the previous laughing, crying, and self-harming behavior. Now, this man who had emerged from 302, looking utterly dejected, carried the kitchen knife and returned to 302. Of course, all along the way back, there were *drip-drip-drip* sounds as blood continuously flowed from his arm.
