On the 19th day post-apocalypse, the group began a thorough sweep of the mall, eliminating all potential threats.
They particularly fortified the passages between the underground supermarket and parking lot with various barriers.
Understanding the interconnectedness between the parking lot and office buildings, they sealed off potential entry points to prevent sudden zombie influxes into the supermarket.
Once internal threats were neutralized, they cleared out new zombie appearances outside the mall with bicycles, cars, and various barriers, creating a secure buffer zone.
They then began transporting supplies by driving vehicles up to the mall entrance.
"Thanks to your team sending people to help us clear out, dealing with so many zombies would have been tough!" someone remarked gratefully.
Seeing things fall into place, Quentin relaxed as the first batch of supplies was nearly loaded onto a truck.
