As long as Wang Bin can take down the remaining two Holy King-level zombies, he can upgrade the System and then bring his family into the apocalypse world.

Before he finished off the Holy King-level zombies, the real world had already become increasingly chaotic, and he did this for the safety of his family and friends.

After arranging for the safety of his family, friends, and their relatives, Wang Bin returned to the apocalypse without any worries.

Upon arriving in the apocalypse, he gathered everyone and set off towards North America once again.
