Read the Message, Reply Nonsense: Building Tanks in Kivotos

Inspired by the book Kivotos Minister of Defense

Because Vilas got ten Colorful units in ten pulls, he was so overpowered that the Yellow Springs train sent him to Chicken Tosis. There, he unlocked the System and began his epic journey through military history. In his previous life, he was utterly useless, but at least he isn't quite so unhinged now. Historical figures meet, and people from opposing factions join forces to fight for the beauty of this world, which hides a massive conspiracy!
