The Strongest Legion in the End of the World

Traveling to a parallel world, I didn't expect that the apocalypse would come and 80% of humans would turn into zombies. There are even various legendary monsters coming, what... Can you get various cards by killing them? And among the cards, only the clan card is honored. "You have a legendary swordsman war group? Killing zombies like dogs? Jian Shen, let them see the power of sword immortals." "You have a ninja war group, very powerful? Haha... How dare these mere barbarians run wild in our country? Five Elements War Group, let them experience what the real Five Elements Escape Technique is!" "You have a sharpshooter war group? Can you kill tens of thousands of zombies? War goddesses, let them feel what despair is!" This is the end of the world where battle groups dominate. Chu Qing, who has been blessed with luck, has an unparalleled super battle group.
