Reincarnated Slime: I Will Attack in Gundam Form

[Another world + non-human protagonist + multi-body control + behind-the-scenes + dark humor + no system] My name is Ilya. I was a senior researcher in my previous life. I was suffocated to death because I forgot to pay the oxygen package subscription fee. After being reincarnated into another world, I turned into a blue slime. At first, I thought I wouldn't survive three episodes. Until I discovered that I could drive humans from another world as "biological mechas." The cold genius sorceress tried to blow herself up and pulled me away? Directly transformed into [Heavy Firepower·French System Mobile Turret SSR]! The proud female knight of the Empire was seriously injured? Take over the movement center, ignore pain restrictions, and transform into a [highly armored and melee-specialized model]! Your Highness the Pure Saint? Comes with advanced recovery techniques, use it as an [infinite battery life, auxiliary medical body]! As for side effects? "I'm sorry, I'm just a slime. The machine is worn out... Just replace it with another one." Some brave men even accused me with red eyes of imprisoning their souls. In this regard, Ilya said: "Don't get me wrong, I am very dedicated." "We are in pure love - they are all my wings." However, people in the other world did not understand this "pure love". When a certain empire devoted all its efforts to encircle and suppress me, they were horrified to find that from border guards to powerful officials in the royal court, my clones had already spread all over the country. When all the countries in the world finally abandon their prejudices and form a mighty crusade, vowing to fight against me... Only then did they realize in despair that the giant mecha I pieced together with countless flesh and blood and magic tools had already blocked out the sky and the sun. "Then let's begin the final test."
