Apocalypse: My Mechanical Empire

My name is Yang Hui, and I was a car repairman in my previous life. The end of the world has come, and I have awakened the [Mechanical Heart] and can see through the structure of all machines. They all thought I was a trash guy who just lived in a garage. It wasn't until I killed the leader who wanted to steal my supplies with one shot that they understood that in this world, whoever masters technology is a god. No Holy Mother, no trouble, but if anyone dares to touch my territory, be prepared to be beaten to ashes. Farm, raise troops, and expand your power. From today on, I will restore order in this wasteland. "Don't talk to me about saving the world, I'm not interested. But I will show no mercy to anyone who blocks my way to survive."
