“Listen, buddy, your cock was the last thing that got inside me, so unless I’m having some kind of miracle baby, yeah, you’re the father. Congrats.”—Raelynn had one goal that night—drown her sorrows in cheap whiskey after getting fired from her job. What she didn’t plan on was two surprises: one, a steamy night with a ridiculously good-looking stranger, and two, a $10,000 check for her the next morning. Jackpot, right?Wrong.Nothing could’ve prepared her for the biggest surprise of all—she’s pregnant. And the father? None other than Elion Vaelorian, the country’s richest and most powerful businessman, with a face that could melt ice... and a personality just as cold.What Raelynn doesn’t know is that Elion isn’t just any man. And the baby she’s carrying? Let’s just say it’s far from ordinary, and its existence could shake the foundations of the world she knows.

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
