So, Zhang Yanhang was preparing to visit all three locations, starting with the gun shop to the west of the apartment to resupply his ammunition, then heading to the slot machines to the northwest to see if he could find a way to bring the machine back, and finally, checking out the Big Treasure Box to the north of the apartment to see if it could actually be opened.
By the time he completed this objective, Zhang Yanhang would have made almost a full circuit around the area. Thus, he planned to advance while clearing the nearby zombies, gradually eliminating all the zombies on the periphery before attacking the large groups of Lickers and Tyrants in the city center.
