It has been six months since the zombie outbreak began, and the survivors, including Ryder, Zoe, Vincent, Lawrence, and Mary, have grown stronger. The WZCD, which stands for the World Zombie Control Department, has been closely monitoring half zombies such as Mary and Zoe, as well as superhumans like Lawrence and Ryder. They have expressed suspicions about Vincent because he has already defeated a level 2 and level 3 zombie.
Meanwhile, NRNDD (NEBULA RnD department) has developed a drone capable of spreading PANTAO, NEBULA's vaccine. They named the drone PSM9 (PANTAO Spreader Mark 9) after a month of mass-producing PANTAO and PSM9. WZCD ordered all countries to spread PSM9 throughout the country and vaccinate every survivor.
WZCD managed to contact Mary and Lawrence and offered them positions as the leader of ZEU3 (Zombie Extermination Unit 3) and the Chief of the Medical Department of WZCD, respectively. The Medical Department is responsible for treating survivors with severe injuries who are not infected. Vincent revealed his secret of possessing a magic gun and how it was created. He was then appointed as the General in charge of all the ZEUs. The government started experimenting on the zombie cores to produce more magical weapons and equip their soldiers with them.
However, WZCD has been unable to contact Ryder and Zoe as they are always on the move. It is unclear what the government's response will be if they encounter Ryder and Zoe, given their exceptional abilities. As the situation becomes more complex, the government and WZCD are forced to consider new strategies to combat the zombie threat.
