Old Archmage Living As A Puppet Girl

Xavius, who thought he would spend his life as one of Great Archmage, never thought that a failed experiment of a student would make him lose his life and sent him to the interstellar times where there are many new things to be learned as well as shocking him at the fact that other than Zoranian, there are also other beings that dominate their own part of the world.
Meeting the descendant of the Trueton, an old frenemy, was definitely wasn't in his plan of wreaking havoc in this new era.
Even more hurt was the fact that the Puppet Girl he possessed was owned by that descendant. Now, not only does he have to learn about new things, he also have to learn that as time goes on, the rules have become more and more strict and compact than before, which pained him a lot when his curiosity is high. Sometimes, Xavius just couldn't help but blow something up out of curiosity

Xavius: "Does taking their newly widespread AR62 that hasn't come out yet to test count?"
Darius: "... Let's have the rules exam tomorrow."
