Jiang Jingchen contacted Ji Yi to ask him about the investigation.
Song Zhou had been injured, so Ji Yi took over the investigative work.
He reported, "The hotel surveillance videos have been tampered with. Almost a full minute had been erased, and in that minute, someone tampered with the car. Phosphorous was hidden somewhere in the car. When the car bumped around, the engine heated up and the phosphorous ignited spontaneously, resulting in sparks which caused the car to explode."
Jiang Jingchen then asked, "Have you checked the people who entered and left the hotel?"
"We are still checking. There were quite a few tourists over the New Year holidays."
Jiang Jingchen was dissatisfied and ordered, "Send me the surveillance videos from the hotel. I'll check them again. Also, why were there so few cars on the road yesterday?"
