Countless rich people were moved to buy the miracle drug researched by the Moebius Foundation at a high price. This miracle drug can indeed delay your life! But the price you pay is to become a zombie like a mad dog! After realizing the crisis, the Planet Federation immediately made corresponding mistakes, but it was obviously too late. Zombies were all over the planet, and the surviving humans could only survive in underground fortifications everywhere! And the mysterious Moebius Foundation also mysteriously disappeared!
