Blood Cross I Have a Radar System

Not Holy Mother, even a little dark Not a cool article, the system is not very helpful Except for the heroine, many characters will die The setting should be as close as possible to the setting of the Blood Cross in the original work (there are actually several versions of the setting in the original work) The end of the world has come, and the Blood Cross Virus has become a reality, turning people into walking zombies who only obey their desires. Social rules no longer apply, and the law of the jungle returns to the world; kindness and morality have become shackles, and only those who are more cruel than the Blood Cross can stand in the world. Long before the virus broke out, the United Nations had established its final base in the Arctic, an extremely cold restricted area that neither humans nor the Blood Cross could set foot on. A crystallization of humanity's highest wisdom and space technology was quietly born, that is, the radar system. And its destiny is to help mankind and defeat the Blood Cross. Therefore, it bound a young man who it thought could best adapt to the current laws of survival in the apocalypse... Putting the best technology in the hands of a beast is a huge gamble...
