The book is also called "The Rules of Counterattack for Mecha Wastebas"!
Once a gamer, he is now a wasteland mecha master. When Han Feng opened his eyes, he became the bottom of the doomsday mecha world - he was naked at the beginning, and his only "car" was a rusty "Little Po Feng". In this wasteland divided between the Iron Empire, the Free City-States and the mysterious Apocalypse, everyone competes for the power of mechas. However, Han Feng has the entire "Iron Armor Era" database hidden in his mind and can see through all the mecha's weaknesses and hidden technologies. When the gate of the abyss of the ancient battlefield opened, the shadow of destruction fell, and the three major forces were defeated. Everyone was running for their lives, only Han Feng drove the assembled mecha that everyone laughed at and charged in the opposite direction.
"What you are fighting for is the present," he declared calmly on the public channel, "and what I want to end is the end."
In the wasteland, the most shabby mecha is about to explode!
