[Delta Force + character transmigration + System + Rules Horror] [This book is lighthearted, fun, and cheerful. No tragic twists.] After staying up late for ages to complete the 33 mission in Delta Force, the protagonist unexpectedly passes out in front of his computer. When he wakes up, he finds himself transformed into Demulan, the boss of Space City, and chosen to take part in Blue Star's Rules Horror. His teammate is also a transmigrator: Clara, a white-haired, red-eyed girl who can repair machinery. Demulan: “The tank's broken again, but the engineer isn't here. What should we do?” Clara: “G-Grandma, I can repair machinery. Can I give it a try?” Demulan: “You can fix it? Go ahead and give it a try.”
