In the hustle and bustle of the city, motorcycle accidents happen from time to time, but what kind of truth is hidden behind each accident?UDI (The Unsolved Mysteries Institute) recently received a special commission to uncover the unknown cause of death behind a motorcycle accident.

Sano, an ordinary factory worker, unfortunately passed away due to a motorcycle accident.However, the truth behind the accident is far from simple as it seems.Sano's mother, Natsuyo, firmly believed that the cause of her son's death was not simple, so she found UDI, hoping that they could uncover the truth about the accident.

The team at UDI accepted the challenge and began investigating in depth.During the investigation, they discovered that the cause of Sano's death may involve multiple aspects: excessive fatigue at the factory, motorcycle repair errors, and missed diagnosis by doctors.Every possible cause pointed to a different responsible party. Factory directors, repair shop managers, and hospital lawyers all came to UDI in an attempt to shirk responsibility.

Faced with pressure from all parties, the Meiqin team remained neutral and decided to conduct an autopsy investigation.After meticulous dissection and analysis, Mikoto's team finally revealed the real cause of Sano's death - an accident.It turned out that Sano lost control of the motorcycle due to sudden physical discomfort at the time of the accident, and eventually died.

However, just as UDI was about to conclude its investigation, they received a threatening letter against Zhongtang.This letter exposed the secrets of Mulin and Zhongtang, and UDI's team was once again in trouble.Not only do they have to face doubts and pressure from the outside world, but they also have to protect their own safety.

Facing the challenge, the Meiqin team did not back down.They decided to continue their in-depth investigation and uncover the truth behind the threatening letter.They believe that only by thoroughly finding out the truth can they give Sano a fair explanation and protect themselves and those around them.
