Forced to Retire, He Tricked Veterans into Applying for the Mecha University

It is known in advance that in two years the earth will be invaded by monsters in turn, and mankind will face extinction. Su Mu deceived twelve veterans who were forced to retire due to disabilities, completed the first recruitment mission of the savior system, and established a mecha university. This university does not teach regular courses such as Chinese and Mathematics, but teaches you how to become a mecha master. The single combat mecha is similar to Iron Man, the super large mecha is similar to Pacific Rim, and the full-body semi-covering mecha controls bullet trajectories, covering all three major fields of sea, land and air. At the beginning, the only students who signed up for this university were retired veterans who were eager to return to the battlefield. Until a year later, monsters came to the earth, causing panic all over the world. Countries were invaded, and humans were powerless to resist. Monsters appeared on the border of the Dragon Kingdom. Su Mu gave an order, and a group of mechas appeared in the sky, ocean, and earth. At that moment, the people of Dragon Kingdom saw the dawn... This novel and its characters are purely fictitious.
