Lin Feng, an ordinary college student, accidentally drowned and activated the RTS real-time strategy system and skill tree. He can build bases on the map, produce troops, and unlock technology and unit capabilities through the skill tree. At first, he kept a low profile and used engineering soldiers to secretly retaliate against the rich second generation who bullied his classmates. Unexpectedly, a zombie crisis broke out in the city, and the official army was retreating steadily. Lin Feng decisively summoned tanks, helicopters and mecha troops to crush the zombie hordes with absolute firepower, shocking the entire network. He took advantage of the situation to disclose his abilities, formed a private armed force, used skill trees to continuously upgrade technology, and gradually developed from a city guardian to a global leader, and finally fought against foreign invaders and established a new human order. The core selling point is the thrill of RTS construction and skill tree growth. The target readers are those who like urban novels and military crushing. The path of enjoyment is pretending to be a pig and eating a tiger → technological crushing → establishing power → protecting the home and country. The core value is to protect the homeland and the destiny of mankind.
