The mission Mu Cheng talked about was from a long time ago, a mission that was a near-death experience; he almost didn't make it back alive.
Generally, before they accepted a mission, there would be a detailed briefing and map, and based on the mission's difficulty, there would be support and assistance personnel.
The mission was challenging, and theoretically, he shouldn't have taken it due to his low rank, but strangely, not only was he required to take it, a stranger with the surname Lei specifically designated him.
But that wasn't the worst part. The worst part was that all the pre-mission information and maps were wrong, almost leading him into a trap, a fall to death.
After several near-misses owing to map errors, Mu Cheng no longer trusted that map. His caution and vigilance saved his life.
