Doomsday Mecha: I Have the Strongest Transformers

[The story behind is very exciting, absolutely beautiful] The interstellar war became more and more intense. Humanity was forced to move underground and set up a mecha academy to train mecha warriors who would cooperate with Transformers. My name is Liu Yu, a seriously ill grandma, a bullied girl, and a pair of disabled legs. In order to survive, I risked my life to enter the Mecha Academy even though I was disabled. Originally I just wanted to be a mecha warrior, but I contracted an abandoned super S-class Transformer with hidden talents. The secret of disability breaks out and the whole world becomes my enemy? Do they think they can kill me and take everything away from me? But there are a hundred Transformers that they are flocking to! Do they think defeating my Transformers will make me surrender? "Haha..." Faced with the siege of the federal warlords. Liu Yu, who was forced to a dead end, just smiled lightly. He is no longer a human being! "The flesh and blood are weak and the machine is soaring!" "Full bombs, fire!!!" ··· The collision of flame and steel, the sublimation of the mechanical core and the machine soul, leads to the mystery of the supreme fire throne. I, Liu Yu. You will definitely fight against fate!
