Mechanical Calamity, I Can No Longer Be the Savior

One-sentence summary: We have invited a father to all mankind. Not too serious introduction: I have an Annihilation Taichu mecha, which is ten thousand feet tall and weighs hundreds of millions of tons. It can push across the world and defeat the heavens. I'm super strong! Come and beat me up with a little monster. In peaceful times, Mu Mo was at a loss when he accidentally got a combat mecha. Looking around, there is nothing useful. It seems that the only use is to drive it and rent it out... How can this be done? I don't accept it. Let's create some villains and give the big mecha a chance to express itself. Damn... I accidentally created too many! In this case, why not just start a turmoil and let me be the savior and lead mankind into a new era? By the way, does it count as operating a mecha when the fetus is in the mother's belly?
