The End Is Coming: I Am Playing Tower Defense

[Doomsday + tower defense + zombie system + no heroine] On April 1, 20XX, a huge meteorite fell in the center of Antarctica. Three months later, an "X-Virus" known as the "Zombie Virus" spread rapidly around the world, and the number of infections increased rapidly. In less than three days, the number of infected exceeded 10 million, and it spread rapidly at a geometric multiple. The huge and uncontrollable number of infections puts everyone at risk. As the number of infections increases and the scope of infection expands, the government gradually becomes unable to control the current social state, and social unrest begins. The end of the world is here. Tangbuping, who was driven back to his hometown after his mother passed away three years ago, has been living in a dilapidated wooden house of 10 square meters near the Huangpu River. There is nothing in the house except a small bed that is wet and cold. There was no one else living near the dilapidated cabin, so it stood alone on a small slope. The death of his mother was a huge blow to Yubuping, and he lived like a zombie every day. On this day, Yubusubei was about to go out to look for food but was attacked by an ordinary zombie before he found the food. Yubusubei finally escaped back to the cabin with lingering fears. Sincerely: Mother in heaven, it's really too dangerous outside, I'd better lie down and wait for death to find you! ——The son who loves you the most: Yubuping. As a result, Yubutsubo, who was lying on the bed, accidentally awakened the "Lying Development" system. How can Yubuping use this system to survive in this apocalyptic world? Stay tuned.
