Although Hope Base is located in Dragon Province, over a thousand kilometers away from Beishi Base, one could reach it in a day or two by car, providing there were no accidents. Not to mention that Zhao Qiankun had control of future technology; if he improved the vehicles, that travel time could be further reduced!
Previously, due to the abundance of zombies, many people dared not venture too far from the bases. However, unlike humans or other creatures, zombies couldn't reproduce. As long as they were continuously killed, their numbers would inevitably decrease, leading to expansion beyond the base boundaries.
The reason Hope Base could become a safe haven in the apocalypse was that many people were still afraid to leave the safety of the base. But as more and more people started to venture out, the peace of Hope Base was inevitably going to be shattered.
