Imperial Marshal Yawen was ordered to kill the genius doctor but unexpectedly turned into a super powerful Omega-type mecha Shou (which can change its shape) without knowing it. When he met the doctor, he started a wonderful exploration story where they disliked each other, insulted each other and had sex.
He, the majestic Imperial God of War, was forced to go into heat with an Alpha who looked like an Omega but was slow, stupid, arrogant and cold, no such thing! Are you blind? You turned a blind eye even if you were sent to me! I'll slap you twice and let you sit on me and cry!
