After waking up, Strong didn't intend to take his herd to join the other underground creatures, nor did he plan to return to All Beings Base. He had already made a big concession by promising Lin Qiao not to attack humans. He would never go back to protect them.
At that time, a huge crowd of zombies had shown up around ten miles from All Beings base. Meanwhile, more and more zombies were still coming to the base from surrounding towns and cities.
The underground creatures, which had finished upgrading and gathered together again, had noticed those zombies. For the lower-leveled ones that weren't picky for food, zombies were edible. However, the ones above level-five weren't willing to eat stinky zombies. They found their taste awful!
They wanted to eat the ones living behind the tall walls, who walked upright. For the underground creatures, the living beings behind the walls were delicious.
