Chen Xin ultimately convinced Qin Lan to stay and take care of his shelter, rather than accompany him on a thousand-kilometer journey back to his hometown to pick up people.
As for how Chen Xin convinced Qin Lan, it was naturally by showing her the various weapons and equipment he had prepared on the tracked armored motorhome.
Seeing the radar, drones, and heavy machine guns installed on the vehicle, Qin Lan knew these things were enough for Chen Xin to protect himself on the journey. As long as he didn't clash with the military, ordinary bandits wouldn't be able to do anything to his armored vehicle.
The only concern Qin Lan had was that Chen Xin was alone, and if something happened on the way, he might not be able to handle it in time.
However, this point wasn't much of an issue, and Qin Lan didn't insist on accompanying Chen Xin on this trip, so after seeing the weapons on the vehicle, she let go of her worries.
