In Bai Yexiong's room, Mu Qinghan and Lin Ran once again entered the study where the murderer escaped.
They have seen the layout of the study many times.
It's just an ordinary study room built on a hill, with no so-called secret passage.
They couldn't figure out how the murderer disappeared into this room without leaving any trace of blood.
"Ran, look."
Mu Qinghan squatted down in front of a round table, stretched out her hand towards Lin Ran, and motioned for her to come over.
Lin Ran had a trace of confusion in his eyes, but without much hesitation, he walked over.
He squatted down where Mu Qinghan pointed.
When she saw the place Mu Qinghan pointed to, a look of surprise appeared in her eyes.
Even incredible.
"What's going on?"
She turned her head to look at Mu Qinghan and asked in a deep voice.
"Is it possible that you didn't notice it when you looked at it?"
Mu Qinghan looked at Lin Ran and gave such an unlikely explanation.
Lin Ran shook his head with certainty.
"impossible!"
She stood up from the ground, "At that time, everyone was looking for the mechanism. They searched every place so carefully. It is impossible for such an obvious blood stain to be left behind."
She pointed at the blood stain on the ground that Mu Qinghan had just found, which had obviously been wiped off but not cleaned up, and said firmly.
"But where did this blood stain come from?"
The question Mu Qinghan asked made Lin Ran frown.
Things seem to be getting more and more complicated.
I always feel like I'm entering one mystery after another, and I can't get around it.
Dragging her chin, she subconsciously walked to the window.
Sight, looking into the distance through the window.
Mu Qinghan also followed to the window, and suddenly saw a strange look on Lin Ran's face at this time.
"What's wrong, Ran?"
he asked.
However, Lin Ran did not answer his question, but fixed his gaze tightly on the neighboring building not far away.
