Mai Dong's idea was a good one.
Prioritizing the search based on the terrain was, indeed, faster than brute force searching every spot. Between Kunlun Station and the Chelomey's landing spot, there were few areas that could be considered precipitous, so it wouldn't take too long to search those areas. Delivering a precision strike was clearly better than carpet bombing. They could complete everything in half a day.
However, Tang Yue wasn't sure if Kunlun Station had the Isidis Planitia's terrain information. Back when America, China, Russia, and other countries worked together to build Kunlun Station, they had gone into a deep discussion about the nearby terrain. They had come up with an extremely detailed map of the area and placed it on the official site of NASA for public consumption. However, Tang Yue wasn't sure if this map was available on Kunlun Station since he wasn't involved in terrain science.
