While Chen Xin was using the virtual system to calculate whether the destruction caused by the nuclear explosion could clear out the underground alien creatures, the military was also paying attention to this matter.
However, the military's approach was somewhat different from Chen Xin's. They did not rely on collecting data for analysis, but instead used various instruments to set up a new surveillance network in the Dongting Lake Region to monitor the underground situation.
This is a lesson learned from previous battles with alien creatures: when aliens dig and move underground, they cause vibrations and leave various traces. These activities can be detected using instrumental equipment.
With the current human technology, these tasks are feasible. Previously, there was no reason to monitor underground, but now that it is known aliens exist there, using this equipment is a natural step, preventing the need for another battle against alien creatures.
