While waiting for the autopsy results of the alleged first victim, Yao wondered why no one had attempted to locate or report the missing child during the day.
"No matter how warm it is during the day, night will always come, darkness will always come. Not all flowers can get sunshine and rain. There is nothing we can do for such things" Jin Yan said.
"Thank you for that poetic answer"
Xun Ran suddenly told Jin Yan to come in, but this time Yao Yao finally ventured to come in. Yao Yao asked why Jin Yan was so curious about the identity of that first victim? is the identity of the first victim important?
"Imagine if about a year ago, your deepest desire to kill people was suddenly triggered. But you still have no way or experience abducting people. How are you going to choose your victim? Are you going to choose the victim you already know, the easiest to kill and the least dangerous"
It's likely that this first victim and the killer knew each other. Maybe a neighbor or a friend or maybe a brother. So if they find out the identity of this first victim then they will be able to find the killer faster.
Jin Yan then measured the length of the victim's pants but he was sure this did not belong to the victim because these pants were too long in size.
Among the other victims' belongings, there was a pencil box that was already very shabby and weathered. They noticed there was writing on top of the pencil box but the writing was already difficult to read.
Jin Yan finally told Yao Yao to just take a picture of it in order to be scrutinized by Zi Yu. Yao Yao photographed it but then, she took advantage of the circumstances to photograph Jin Yan as well.
While browsing through the collection of other photos, Jian Xuan looked at the evidence photo of the pencil box and instantly recognized it as the pencil box the school had once given him.
Thanks to the information from Jian Xuan, Yao Yao and Jin Yan went straight to the school. But Jin Yan was sure that the victim was not a student of this school because this high school was the best school in this area so if there was one of the students missing then it would definitely be reported immediately.
One of Yao Yao's acquaintance teachers said the pencil case was a gift given to students at last year's autumn sports festival and that 14 students got the pencil case.
The students who got the pencil case are now on vacation but the teacher has told them all to go back to school now.
Jin Yan suddenly left but he told Yao Yao to stay behind to interrogate the disciples who had the pencil case. Yao Yao finally interviewed the disciples alone.
But unfortunately, none of the answers can give a clue because most of the students have thrown away the pencil box or given to his brother.
Meanwhile, Xun Ran and his partner were busy traveling from one store to another looking for information on the purchase of knives used by the killer. But there is no evidence of suspicious purchase transactions.
