"You met Director Wang and Lao Chen Tou at around half past eight, can you tell us how long you stayed there before you met these two people?"

This should be the most important place in the whole case. If Da Youdao hadn't seen anyone before half past eight, then the comrades' investigation would have left Rong Guiyu and the students of Guli Elementary School.

"When I walked to the wharf of Peng Datou's house, I heard someone shouting Mochizuki's name - it was Mochizuki and her mother calling Mochizuki's name, and then there was a noise - the noise was louder than a loud noise, and then several people were shouting Mochizuki's name, and there were dogs barking, first two or three dogs barking, and then many dogs barking, and only when something big happened in the village, the dogs barked, so I ran over, and when I ran to the waist of the gourd, the school was beating the preparatory bell -- it was the preparatory bell for the first class in the morning."

"Where is the dock of Peng Datou's house?" Liu Dayu asked.

"From the wooden bridge to the pond, isn't there a family in the middle? There is a small boat parked on the pier, which is Peng Datou's home. "There is a way.

Liu Dayu and Chen Jie have a little impression of this family.

"What time is the bell for the first period?"

"It's seven fifty."

This time is relatively close to the time of Gu Wangyue's murder, the time of Gu Wangyue's murder is between seven o'clock and seven and a half o'clock, seven fifty o'clock, and the difference is only twenty minutes in between, if Gu Wangyue was killed at about seven and a half o'clock, then it will take about ten minutes for the murderer to leave the crime scene and return to the place where he entered the water, that is, the north shore of the gourd's waist.

"What did you see when you got there?"

"I saw a lot of people standing near the pier of the ancient family and the pier, and several boats rowed towards the pier of the ancient family."

"Have you seen anyone at or near where you have stayed?"

"Nope."

"In about ten minutes, the murderer left the crime scene, which should be relatively calm."

Everyone was very disappointed with Da Youdao's answer.

"But—" Da Youdao frowned, looking thoughtful.

Everyone was excited again.

"Da Youdao, what do you want to say?"

"Somebody just came up from the water."

"Someone just came up from the water?" Liu Dayu grabbed Da Youdao's words tightly, for fear that they would be fleeting, "What is your basis?" ”

"The water near the shore is muddy, and the reeds on the shore are lying on the ground, and the reeds will lie on the ground only if a person has stepped on them, and the key is that there is water and silt on the dead grass on the shore and the reeds lying on the ground."

The north shore of the gourd's waist is indeed the place where the murderer enters and exits the water.

"How long have you been there?"

"Soon after seeing Lao Chen Tou and Director Wang, I left."

"Where have you been?"

"I went to the dock of the ancient family."

"Everyone else participates in the salvage, at least to show concern, you just said that Gu Lirao's mother and son take good care of your family, why don't you go over immediately to help save people?"

"I want to wait for the muddy waters to clear." Da Youdao only said half of it.

"Wait for the muddy waters to clear? What do you mean? ”

"When the water clears, I can see the footprints underneath the water."

The author has explained more than once before that near the riverbank, the water is relatively shallow, and the aquatic plants are also cleaned by the villagers, so if someone walks underwater, they will definitely leave footprints.
