Transmigrating into Build, Copying the Rabbit Bottle from the Start

This story has no female lead! No female lead! No female lead! That's important, so I'll say it three times! It contains a Long-Tu pairing, so proceed with caution. There's a System! The System is quite prominent at first, but will appear much less later on. There may be some OOC moments, so apologies in advance. Also, the story mainly focuses on Build's movies and TV series! Zi-O and Build will show up later. The protagonist may also write some notes and things like that (a bunch of random stuff). (The story description starts below.) What? Someone copied the Rabbit Bottles?

Sento: He's a mysterious scientist.

E Total: His abilities are a mystery.

Author: The three idiots with Squeezing Drivers have become four!
