"How did you wake up this morning?"

Without hesitation, Fatty replied, "I was woken up by the pajama girl's scream. She shouted that someone was dead."

"Okay, and what did you see when you ran out?"

"Everyone was gathered around a door, and there was a large pool of blood on the floor in front of the door..." he explained, recalling the scene.

"What about the pajama girl?"

"She..." Fatty thought hard for a moment. "She was sitting on the ground, as if she was terrified, screaming non-stop. Eventually, the baseball cap guy slapped her to calm her down."

"Do you remember her position?"

"I remember," Fatty paused, as if something wasn't quite right, but he still honestly answered, "She was behind the crowd, opposite the door where the incident happened."

He described the scene very clearly.

"Is there a problem with that?" he asked.

"Of course, there's a problem," Jiang Cheng said calmly. "Her position is wrong."

"The room where the incident happened didn't have a number, but checking them one by one in order, it should be room 414, which means the room where the incident happened is closest to our room, 407, only four rooms away."

"It was already bright at the time. Logically speaking, the pajama girl would have quickly noticed the large pool of blood in front of the 414 room as soon as she left her room, and immediately screamed. How could she have waited until she reached the door of room 414 to start screaming and then collapse there?" Jiang Cheng looked at Fatty. "She's not blind."

Fatty's eyes widened as he looked at Jiang Cheng in disbelief.

It had to be said that this was indeed very contrary to common sense.

"That's just the first point," Jiang Cheng didn't give Fatty a chance to speak, and continued on his own, "Second, as a newcomer, and with her only roommate having left the night before, with their whereabouts unknown, what gave her the courage to be the first to push open the door and walk out, not worried that there would be a ghost standing outside the door?"

Jiang Cheng continued, "If I were her, I would never do that, nor would I dare to do that."

"Wh...what's the third point?"

Jiang Cheng paused for a few seconds, and slowly said, "The qipao woman's body was moved. Someone had been there before we arrived."

Fatty thought for a while, then raised his head. Just as he opened his mouth, he heard Jiang Cheng say, "I know what you want to say, you think ghosts might also do something to the body, right?"

Fatty nodded.

In the last mission, Sister Nuan's body was taken away by a ghost and hung upside down on a cross. And the clerk, Xie Yu, was wrapped in a quilt and dragged away after being scared to death by a ghost, suffering abuse.

"But the strange thing is that the qipao woman only had one wound on her body, which was her broken jaw," Jiang Cheng pondered for a moment, then continued, "But the position of the pankou (Chinese frog fasteners) on her qipao collar had changed."

"Pankou?" Fatty frowned. "Position?"

"Yes," Jiang Cheng nodded. "There were three pankou on the collar of the qipao woman's qipao. The first time I saw her, she only had the top two buttoned. When someone ran out of room 404 before going to bed, she was also startled and came out. At that time, she still only had the top two buttoned, and the last one at the bottom was open."

"But on the qipao woman's body, all three pankou were buttoned neatly."

"I don't think a ghost would be in the mood to button up the last pankou for her after killing someone," he glanced in the direction of the dormitory. "So, I think the most appropriate explanation is that someone carefully checked her body after her death, but in the process of restoring it, they ignored this inconspicuous button and hastily fastened it together."

"Doctor," Fatty said, "First of all, let me state that I agree with most of your reasoning, but this one button..." He paused. "Couldn't it be that the qipao woman buttoned it herself?"

"No," Jiang Cheng replied affirmatively.

"Why?"

Jiang Cheng took a deep breath, held his hands in front of his chest, and made an ungraceful gesture. "It's very simple, because if she buttoned up this third pankou, she would be squeezed and unable to breathe."

Fatty's eyes lit up, and he instantly recalled the qipao woman's amazing figure.

Her face was unremarkable, but when it came to her figure...

After a while, Fatty nodded vigorously. "Doctor, you're right. I completely agree with your statement."

"If all of the above is just reasoning based on common sense, then the last point is the ironclad proof against the pajama girl," Fatty suddenly felt that Jiang Cheng's image was getting taller and taller. He only heard the latter say, "There was blood on the soles of her shoes. I accidentally discovered it when she collapsed on the ground."

"I understand that," Fatty said excitedly. He finally felt that he was on the same wavelength as Jiang Cheng. "Judging from her personality, she would never dare to step on a bloody place. She didn't enter the room before we arrived, so her persona is self-defeating. She was the one who moved the body before we arrived at the scene!"

"No," Jiang Cheng shook his head. "The blood on the soles of her shoes isn't the most important thing. It can also be explained as her accidentally stepping on it, or an unconscious behavior caused by excessive fright. That's not ironclad proof."

Fatty's enthusiasm cooled down. "Then what is ironclad proof?"

"There's blood on the soles of her shoes, but not on the sides," Jiang Cheng moved his stiff neck slightly. For the first time, he realized that analyzing a case for Fatty was more exhausting than solving it himself. "The sides of her shoes are very clean, as if they had just been cleaned."

Fatty cleared his mind, and after a few seconds, he revealed a look of sudden realization.

That's right, Jiang Cheng was right. Blood on the soles of the shoes wasn't a big deal. He himself, and Jiang Cheng, must have blood on the soles of their shoes.

Not only the soles, but he also lowered his head and realized that there was a layer of bright red color on the sides of his shoes.

So was Jiang Cheng.

Everyone who entered the room would more or less get some on them. After all, the qipao woman's blood had already covered the ground, and in some places, it had even formed pools of blood.

But intentionally cleaning the blood from the sides of the shoes would be very telling.

She had a guilty conscience.

Otherwise, why would she do that?

The old problem was cleared up, and a new problem surfaced. "Doctor," Fatty bit his lip and looked up. "Why would the pajama girl do this?"

The disadvantages of killing a teammate were obvious, especially since the qipao woman was not a newbie.

"Fatty," Jiang Cheng said gloomily, "Don't you think the pajama girl looks a lot like someone we know?"

"Who?" As soon as Fatty asked this question, a figure immediately appeared in his mind. He trembled and said, "Are you talking about the innocent girl?!"

"Yes," Jiang Cheng glanced at him. "She said her name was Chen Xiaomeng, but I guess it should be a fake name."

Fatty seemed to have realized something, and his lips began to tremble unnaturally. "So... "

Jiang Cheng nodded, his face also becoming unnatural. He unscrewed the cap of the half-empty bottle of mineral water, took a mouthful, and didn't swallow it.

"The pajama girl is Chen Xiaomeng transformed!!" Fatty shouted.

Jiang Cheng couldn't help but swallow the water in his mouth, then started coughing frantically.

He choked.
