The rise of death 2 is the task of saving survivors ~ it is the task of SMS reminder ~ the great gods help.

Limited, and there is a time limit. After time passes, the survivor dies or the task expires, and the main task can also expire. After the expiration, the main line will have nothing to do (it is also a failure for a daughter to become a zombie). . . . After the main line fails, you can continue to save people as side lines, but it will be less fun. . . . . The short message prompt (i.e. the feeder) is triggered randomly within the specified 3-day period, and partially hidden. . . . As a branch line, after the completion of each main line, you will be prompted that "the next incident will occur at XXXX time", and the free time during this period is enough for you to save lives as a branch line. . PS: You can also get off the bus and cheat to freeze the time and do it slowly. . .
