Tomb Raiding: One Transmigration, a Lifetime of Comfort

Note: Be sure to read the entire synopsis. Note: This story is told in the first person and is unfinished because the author ran out of steam halfway through writing it. The protagonist is clever, levelheaded, and not romance-obsessed. He knows how to use human nature to his advantage. The story is mainly funny and fantastical, with a few brain-teasing elements. The early atmosphere is lighthearted, though things get a little angsty later on. There is no fixed pairing, so ship whoever you like. The characters from the original The Grave Robbers' Chronicles may be out of character, so I apologize in advance and hope you'll understand. The proper synopsis: My name is Lu Wenzheng. I'm a fine young man from the 21st century, the campus heartthrob of Huaguo University of Political Science and Law. Somehow, I ended up inside The Grave Robbers' Chronicles. Uh... this is bad. My identity turns out to be... The System tells me I can't act out of character, but the original owner's personality is nothing like mine, so it's really hard to keep up the act. I've nearly given myself away several times, but luckily, there's always a bunch of people there to cover for me. They love me and treat me so well. I've always thought of them as my own big brothers. I never expected them to want to *?! I'm straight! I'm straight!! I'm straight!!! Some System: Straight, my ass. You grin like an idiot at a bunch of handsome men every day, and you still have the nerve to say you're straight? Me: ...Get lost.
