According to Tomcat, to survive the intense quake that would envelop the northern hemisphere of Mars, Tang Yue needed to dismantle Kunlun Station and break it down to its elements to roll with the punches. Once the quake was over, they could rebuild Kunlun Station.
Tang Yue had never attempted to dismantle Kunlun Station before. This massive tent was indeed modular in design, the designers had racked their brains to reduce Kunlun Station's weight and reduce the complexity involved. Otherwise, the astronauts from the seventh landing mission wouldn't have been able to set it up with their hands alone.
However, the engineers on Earth had probably never considered the problem of dismantling.
Kunlun Station was going to be a permanent base that would sit there from the day it was built until the day it was abandoned. No one had expected to dismantle it.
