A forensic doctor is reborn, sir, please don't bully me!

Chapter 197 Exploration

Bai Mengfei slowly walked down the stairs, her eyes fixed on the floor as she went, trying to find even the slightest clue.

Soon enough, she actually made a discovery!

There was a square mark on the floor that looked particularly out of place.

Bai Mengfei immediately squatted down and quietly observed the mark, even using her fingers to measure its size.

The mark was very small, square in shape, and its length and width were only about the length of one or two finger joints of Bai Mengfei, about one or two centimeters.

How could such an abrupt mark appear on a clean floor?!

After observing the mark from different angles, Bai Mengfei stood up and turned to look towards the doorway.

When she turned around, she was startled to see a person standing there.

"oops!"

She gasped softly, her eyes widening as she looked closely before recognizing Jiang Shuai standing there.

"General Jiang, what brings you here?" Bai Mengfei asked in surprise, "And you stood here so quietly, it scared me to death!"

Jiang Shuai chuckled and said, "Seeing how focused you were on your investigation, I didn't want to disturb you. But have you discovered anything?"

"No." Bai Mengfei shook her head slightly, somewhat disappointed. "I only saw this small mark, but it doesn't seem to be of much use. This square mark is too ordinary."

"Let me take a look." Jiang Shuai said, stepping forward.

Jiang Shuai was also quite intelligent, and seeing that he wanted to see it, Bai Mengfei let him.

However, after looking at it for a while, Jiang Shuai frowned, shook his head, and said, "I don't understand it. Forget it, don't look at it anymore. Maybe it was left sometime in the past?"

"Impossible! Look at this floor, it's clearly been replaced recently! And I was here yesterday, I didn't notice this little mark then."

"Well, so what?" Jiang Shuai shrugged helplessly. "I only know that Xiang Yuntian asked me to protect you, but I feel that if something really happens, I might not be able to protect you, so it would be best if you came with me."

After saying that, Jiang Shuai saw that Bai Mengfei was still studying the mark intently, looking at the mark for a while and then looking around. He couldn't help but get a little anxious and said, "Alright, stop looking at it and let's go."

“I’m not leaving. If you want to leave, then leave by yourself,” Bai Mengfei insisted.

Jiang Shuai, growing impatient, stamped his foot and said, "Are you coming or not? If you're not coming..."

Before Jiang Shuai could finish speaking, he noticed that Bai Mengfei was staring at his feet.

Just as Jiang Shuai stomped his foot, Bai Mengfei had a sudden inspiration: this little mark might have been left by stomping high heels. Bai Mengfei blinked quickly, shifted her gaze back to the mark, and fell into deep thought.

After thinking for a moment, Bai Mengfei finally understood and said, "I know, the murderer might be his ex-girlfriend!"

Because Bai Mengfei remembered that Lü You had stood there that day, reminiscing about his first girlfriend!

"What ex-girlfriend? I heard Yun Tian mention that the person who died in this case was his ex-girlfriend who broke up with him, right?" Jiang Shuai asked doubtfully.

Bai Mengfei raised her head and said with certainty, "Actually, before that, Lü You had another girlfriend, but that girl was very unreasonable, so they broke up. At that time, his girlfriend wanted both money and his company, so she left in the end."

"You mean, she's back now? She was jealous of Lü You's current girlfriend, so she killed her to try and regain her place in Lü You's heart, is that right?" Jiang Shuai's imagination was quite rich.

However, Bai Mengfei shook her head and said, "That's not how it is."

"Hmm? What is it?" Jiang Shuai frowned, his face full of doubt.

Bai Mengfei turned to look out the window and said, "I'm not quite sure yet, but as long as we can find her and her high heels, and if there's a pair of heels that match this mark, there's a 40% chance that she's the murderer."

"Only 40%?" Jiang Shuai asked curiously.

Bai Mengfei nodded and said, "Yes, because it could also be a coincidence. The murderer might have been wearing the same shoes. Or she might have indeed been here and lost her temper, but Wang Tian wasn't injured by her. It's hard to say."

Jiang Shuai then suggested, "Why don't we just go to the hospital and ask Wang Tian directly? That might give us a clearer picture."

Bai Mengfei gently shook her head and said, "No, I think if Wang Tian knew anything, she would have told me long ago. She was probably ambushed, so we won't get any useful information out of her. On the contrary, this is the primary crime scene, so there should still be many physical traces left."

After saying that, Bai Mengfei prepared to continue her investigation.

Jiang Shuai walked over and tried to stop her, saying, "Alright, stop looking. You know, we might not find anything if we keep looking like this."

"If you want to leave, then leave on your own," Bai Mengfei said again.

Jiang Shuai said, "What if the owner of this place comes back? How will we explain all this? We might even be mistaken for the murderer!"

Hearing this, Bai Mengfei thought it made sense, but she didn't choose to go with Jiang Shuai. Instead, she took out her phone and called Zhao Fei directly, saying, "Captain Zhao, I'm with Lü You right now. Wang Tian came to investigate just now and got injured. Could you please send someone over?"

After saying that, Bai Mengfei hung up the phone decisively without waiting for Zhao Fei's response.

Jiang Shuai stared in disbelief and asked, "Did he hear you? He hung up right after you finished speaking!"

"You must have heard me, right? Anyway, I've already told him, whether he comes or not is his business." As she spoke, Bai Mengfei noticed a lipstick in the corner of the kitchen.

Bai Mengfei walked over and picked up the lipstick with her sleeve.

Judging from the cross-section of the lipstick, it broke when it was dropped, resulting in a flat but uneven wound.

This is similar to examining a corpse; after a person dies, the body is treated like an object.

Conversely, the damage to objects is similar to the damage to the human body.

Bai Mengfei then turned around and searched the surroundings for the other half of the broken lipstick. If she could find it, it would prove her deduction was correct.

She glanced back and found the broken half of the lipstick right there.

Seeing that she had made another discovery, Jiang Shuai walked over and asked, "What did you find this time? Does this mean we can solve the case?"

"This is called collecting physical evidence, which is what forensic experts do when investigating a crime scene."

Out of consideration for Jiang Shuai's many times of help, Bai Mengfei earnestly explained to him.
