Yi Weilan also focused on investigating all the roads leading to the West Courtyard.

There are three roads leading to the West Courtyard. The first is the path leading from the East Courtyard to the West Courtyard, which is mainly a teaching area. The second is the three female dormitory buildings, and there is a road leading to the west courtyard after turning right. The third is the path at the back door of the two boys' dormitory buildings.

There was only one luminol reaction, in the direction of the three women's dormitory buildings.

Qin Xiao applied to the school to inspect the three girls' dormitory buildings, and the school leaders thought it was ridiculous, how could the murderer be in the girls' dormitory.

"The murderer doesn't have to be a female student, but isn't it possible that the murderer hid in the girls' dormitory or left some evidence?" Qin Yu explained to the school.

The school leaders were silent. Although they have always been at odds with Follen, three Follen students died at their school, and if they don't give an explanation, it can easily cause disputes between the two countries.

In the end, the school agreed to let Qin Xiao take someone to inspect the three girls' dormitory buildings and the surrounding area.

At the time of inspection, everyone in the dormitory should be emptied. Xia Ruchu stood outside the line and looked at it for a while, and then said: "I can't finish the inspection for a while, let's go eat first." ”

On the way to the cafeteria, Zhiyan said to a few people, "You go first, I'll go to the bathroom." ”

Turning a small path, Childish Smoke walked to a small garden at the back door. Because of its remoteness, few people usually wander around this small garden.

Approaching the rockery, Zhiyan pulled out a small bamboo box from a small hole that was not obvious. I saw a small pentagram carved on the box. After quickly reading the message, Childish Smoke took out the reply letter prepared in advance and put it inside. Looking left and right, there was no one around, and she pulled out a small whistle with a strange shape out of nowhere.

A sound like a kiwi birdsong sounded, and there was no girl in the same place.

Inspecting a residence hall is no small amount of work.

"Only the stairs on the first and second floors on the left have a reaction, and when you get to the third floor, the blood reaction is all gone." Yi Weilan reported.

"Focus on the first, second and third floors." Qin Xiao said in a deep voice with a lighter

Unexpected, yet reasonable. Except for the stairs on the first and second floors on the left, there is not a single luminol reaction in the entire dormitory building, including the third floor of the key investigation.

Qin Xiao stood in the corridor on the third floor, frowning and thinking. Ethan's pentagram always felt familiar to him. And this traceless modus operandi also reminded him of the incident that Yu Ge encountered last time.

"Team Qin!" A small police officer interrupted his train of thought.

"James has found a pentagram on him!"

—

"How is that possible?! Haven't you had a full body checkup before? Qin Xiao looked at James's corpse in disbelief.

On James' left index finger, a small pentagram filled everyone's eyes.

Qin Xiao's right hand clenched into a fist and slapped his left hand unhurriedly, "Are you sure that your whole body has been checked before?" Didn't miss a single detail? ”

Yi Weilan leaned over to study the pentagram in James's hand and replied, "I'm sure and very sure, there wasn't a pentagram here before. ”

Qin Xiao walked around James's corpse, "Can this trace determine the time?" ”

"Yes, judging from the changes in the blood and tissue cells of this trace, it was indeed left last night." Yi Weilan didn't understand, if it was at the moment of the murderer's murder last night, then what means did he use to make the pentagram appear today, and what was his purpose?
