"Help! Help!!!"

Shi Heyan was terrified and her screams filled the entire room.

Suddenly, a familiar laugh rang out in the room.

"Ha ha ha ha……"

Shi Hexuan threw off the blanket and grabbed Shi Heyan's hand, laughing heartily.

Shi Heyan was stunned for a moment, and only then, with the light from the window, could she see clearly.

Upon seeing that it was Shi Hexuan, she was instantly filled with rage and pounced on him, punching him several times on the head.

"Shi Hexuan, you dare scare me! You're asking for it!"

Shi Hexuan was chased all over the house, begging for mercy as he ran:

"Sister, I was wrong! I know I was wrong!"

Shi Heyan got tired of playing and stopped to put the room card back in.

"I just closed the door, how did you get in?"

Shi Hexuan pointed to the window:

“Look! Your window is open. I live next door to you. I can easily climb over from the roof beam.”

Upon hearing this, Shi Heyan was shocked and slapped Shi Hexuan hard again:

"Are you crazy?! This is the tenth floor! You climbed all the way up here just to scare me. What if you fell and died?!"

Shi Hexuan scratched the back of his head and laughed:

"It's okay! I didn't fall!"

"When you came back, you seemed distracted and a little scared, so I wanted to help you release your fear. You just shouted, are you feeling better now?"

To be honest, after being scared by Shi Hexuan, Shi Heyan did feel much better.

"Alright! You should go back now, I'll be fine on my own!"

"Okay! You should get some rest!"

Shi Hexuan left through the main entrance.

After he left, Shi Heyan took a deep breath and felt much more relaxed.

She peeked out the window and saw that there were indeed many crisscrossing beams below. It wasn't surprising that Shi Hexuan, who liked fitness and parkour, could climb in.

Shi Heyan closed the window, lowered the lock, drew the curtains, and went to wash up.

But what she didn't see was that a second after she entered the bathroom, the window lock opened automatically, the window was slowly pushed open, and the wind gently blew the curtains, as if bringing something in.

...

The next morning, Gu Xicheng and Lu Qing spent the night on the speedboat, not returning until dawn.

On their way back to the hotel, they heard sirens and saw police cars driving by.

In the distance, a large crowd had gathered in front of another hotel, as if something had happened.

Lu Qing calculated with his fingers, then sighed and said:

"She still couldn't escape!"

Gu Xicheng paused for a moment, then frowned and said:

"It's Shi Heyan!"

Lu Qing nodded slightly.

"Would you like to go and take a look?"

Gu Xicheng pursed his lips: "Go ahead! I've known them for so long, after all!"

Gu Xicheng values ​​relationships. Even though he hadn't seen Shi Hexuan and Shi Heyan for several years, he still remembered the friendship he had with them in college.

Lu Qing nodded slightly and took Gu Xicheng's hand, heading towards the area with the largest crowd of onlookers.

Excuse me! Could you move aside?

Lu Qing pulled Gu Xicheng to the front, and then saw Shi Heyan lying naked in a pool of blood from afar.

After the forensic doctor finished the examination, he kindly covered her with a white sheet to preserve her final dignity.

Shi Hexuan was explaining the situation to the police not far away when he saw Lu Qing in the crowd.

Remembering what she said last night, Shi Hexuan rushed over:

"Lu Qing! Lu Qing, do you know how my sister died?! Don't you?!"

The police immediately pulled him away.

"Sir, please calm down!"

Shi Hexuan roared in fury: "My sister is dead! How can you expect me to stay calm!"

"Lu Qing, did you do something to my sister? Did you?"

Upon hearing this, Lu Qing frowned immediately, and Gu Xicheng also looked displeased.

"Shi Hexuan, if you keep talking nonsense, don't blame me for being impolite!"

Shi Hexuan glared at them, his bloodshot eyes filled with rage:

"Gu Xicheng, ask yourself honestly, am I really talking nonsense?"

"What she said to my sister last night, do you dare say she really didn't know anything about it?"

"Lu Qing, is it because my sister likes Gu Xicheng that you want to get revenge on her?!"

Lu Qinggang hadn't held a grudge against Shi Hexuan because he was overwhelmed with grief, but now she couldn't take it anymore. She crossed the blockade, strode forward, and slapped Shi Hexuan across the face.

"Are you awake now?" Lu Qing asked coldly, staring at him.

"Madam, you cannot enter here. Please leave immediately!" the police officer shouted.

Lu Qing took out his police consultant badge and handed it to him:

"Take this to your bureau chief and tell him that I want to be involved in solving this case."

Ordinary criminal police officers are not qualified to know about the Investigation Bureau, but local bureau chiefs do.

Lu Qing then called Li Hui again and explained the situation to him.

Li Hui immediately contacted the local police station in charge and asked Lu Qing to get involved in the case.

In the police station, Shi Hexuan sat opposite Lu Qing, tears welling in his eyes, and remained silent.

Shortly after, the forensic doctor walked in.

"Advisor Lu, the preliminary assessment of the deceased's cause of death is that he fell from a building. The multiple fractures were likely caused by hitting a beam during the fall. However, it is difficult to determine whether it was suicide or homicide!"

Shi Hexuan immediately stood up and retorted:

"Impossible! My sister would never commit suicide!"

Lu Qing frowned, let out a soft breath, and looked at Shi Hexuan, saying:

"Your sister didn't commit suicide, nor was she murdered!"

Shi Hexuan: "What do you mean?"

Lu Qing: "What killed her was a vengeful ghost, or you could say it was retribution."

Upon hearing this, Shi Hexuan let out a sneer:

"Lu Qing, do you think I'd believe that? Last night you were talking to my sister in a cryptic way, and now you're saying she was killed by a ghost!"

"If ghosts really exist, then let me see my sister's ghost. I want to ask her myself who killed her!"

Lu Qing: "Your sister's soul has been taken away by that vengeful ghost. You can't see her for the time being, but I can tell you why your sister died!"

Shi Hexuan's eyes trembled slightly: "You...you really know who killed my sister?"

At this moment, Gu Xicheng walked in, holding a document in his hand.

"This was just delivered by the bureau chief."

Lu Qing handed the document directly to Shi Hexuan: "Take a look for yourself!"

Shi Hexuan quickly opened the file; it was a murder case that had occurred three months prior.

The perpetrator was a habitual burglar, the victim was a 25-year-old single woman, and the crime scene was a residential complex.

The deceased was assaulted and then fell from the 20th floor, dying in a manner similar to that of Shi Heyan.

Police investigation revealed that the deceased had made three emergency calls before his death, but the total call duration was less than one minute, and there was no record of the police responding to the call.

Based on the recording and the perpetrator's subsequent confession, the police roughly deduced what happened.
