National Mecha? I Summon Billions of Monsters with My Backhand!

The era of mechas is coming to an end! My name is Mu Yuan, a battlefield sweeper and the sole owner of [God-Level Monster Ranch]. When the S-class mechanical beast trampled the pride of mankind, the S-class mecha [White Knight], I was forced to take action. So, my monster ranch began to evolve crazily! D-level [Skeleton-eating Worm] → Devour the core of S-level mechanical beasts → Unlock [Monster Arms], combat power x100%! An alien spacecraft → absorbed [Descendant of Cthulhu] → transformed into a floating base [Lair of the Abyss], and its technological level increased by 300 years! Kill the [Mechanical Beast Queen] → Unlock [Gene Targeted Editing] → The monster legion can be mass-produced! Federal Marshal: "Your Excellency Mu Yuan, please take action to save the world!" Mu Yuan: "Okay, that crashed alien flagship belongs to me." Cult of the Mechanicus: "Submit to mechanical ascension, otherwise it will be destruction!" Mu Yuan: "Just in time, my [Magneto King Emperor Meteor Dragon] is hungry." From summoning monsters to forming a monster army! From floating base to interstellar ark! Establish a monster dynasty and everyone can control the beasts! My goal is to make the roar of monsters resound in every corner of the universe! I, Mu Yuan, will lead human civilization onto a new evolutionary path!
