Ji Shuyun obviously thought the same thing as his sister.
He clenched his fists, his face grim. "If the Xia family only learned about the feed being sent to the zoo after meeting with Professor Ning, then the murderer could only have placed the kite string inside the truck after it departed from the agricultural base."
Ji Shuyun turned to the driver, his eyes piercing, "Driver, please recall carefully, did the truck stop anywhere during its journey?"
The driver frowned and tried to recall: "The car did stop twice on the road..."
"One time, I got off the car in front of the Huimin Convenience Store and bought a pack of cigarettes."
"Another time, we stopped at the Dongjiao petrol station and went to the restroom. Then we drove straight to the zoo without stopping again."
Xia Zhining immediately grasped the key point: "The zoo's surveillance shows that no one other than Professor Ning's team has approached the truck. The problem must have occurred during these two stops!"
Ji Shuyun immediately pressed the issue: "Please tell me the exact time and location of the two stops."
He turned to the building and said, "We need to retrieve the surveillance footage from these two locations immediately."
Lou Yu frowned, "Officer Ji, are you so sure that it was Mr. Xia Cheng who did it?"
"It's disappointing that they didn't reach a cooperation agreement. We need to rely on evidence when handling cases. We can't make assumptions just because you and your sister have a problem with the Xia family."
Ji Shuyun looked calmly at this senior who was three years older than him.
Lou Yu looked at this young man who had served as the leader of a special task force, and he felt a little dissatisfied.
"Since we have different opinions," Ji Shuyun said calmly but firmly, "let's each find evidence to prove our own judgment."
Lou Yu raised an eyebrow: "Okay."
Professor Ning saw this and asked, "Can we leave now?"
There was really no reason for the building to stop them, so they could only nod and let them go.
Xia Zhining was about to go get some feed samples from the truck to send for testing when Lou Yu spoke up first, "We'll arrange for a unified testing agency to conduct the feed testing. This is important physical evidence and requires standardized circulation."
Professor Ning gently took Xia Zhining's hand and said warmly, "Zhining, leave the testing to the police."
"We have a collaboration we'd like to discuss with you. Are you interested?"
Ji Shuyun touched Xia Zhining's head and said, "Ningning, leave the investigation to your brother."
"Talk to Professor Ning."
Her brother gave her a reassuring look and Xia Zhining nodded.
After Xia Zhining and Professor Ning sat down in the principal's office, Professor Ning stated his purpose straight away:
"Director Xiao Xia, there has always been a headache with the experimental fields at our base."
"Birds and rodents are always coming to eat crops, which seriously affects the progress of scientific research."
"We want to find a method that is friendly to the ecological environment and can effectively protect adults."
She pushed her glasses up, her tone carrying the rigor and helplessness typical of a scientific researcher: "Sending people out every day to evict them is a huge drain on manpower and resources. Funds are burning through quickly, and it's hard to prevent them."
"Especially since I'm going on a business trip to Beijing next, there's a batch of seeds of various varieties that must be cultivated outdoors in the sun..."
