A Mudslide in the World of Tomb Raiders

Also known as The Years I Was the Unluckiest Guy in Grave Robbers' Chronicles Tan Xuan accidentally transmigrated and brought along a System. The System was called the Tomb Raider Sign-In System. He could gain new abilities and treasures by fighting monsters, looting tombs, and encountering designated people, events, or places. This was all pretty normal. The problem was that the Host was spectacularly unlucky. He signed in outside the tomb of the Huo family head and gained the ability: [Pale Skin] ? Tan Xuan stared in confusion. Never mind, let's try again. No way I could be this unlucky every time! The second time. He signed in outside Xiang Yu's tomb and gained the ability: [Strength Enough to Lift a Ding] ?? Tan Xuan stared in confusion again. Where's my [Divine Beast Bloodline]? Where's that gigantic [Divine Beast Bloodline] I was supposed to get? I don't need to lift a ding, thanks! Never mind, let's try again! He signed in outside the Zhang family home and gained the ability: [Indestructible Rich Woman's Pleasure Finger] ??? Tan Xuan was completely dumbfounded. When I type three question marks, it's not because I'm confused. It's because there's something wrong with you! Is this really a legitimate prize draw? Tan Xuan was starting to think the System had scammed him. Pupils quake.jpg. Does this System have no sense of decency?! In that case... Don't blame me for having no decency either! (╯‵□′)╯︵┻━┻ Basically, it's a story about a goofy male lead in Grave Robbers' Chronicles. Note: The male lead is spectacularly unlucky in small things. Extremely unlucky, the kind of luck that could turn him to carbon! But when it comes to major events, his luck is out of this world, and he can always find a way out of seemingly hopeless situations. His personality is gorgeous, strong, and playfully mischievous. The characters from Grave Robbers' Chronicles are somewhat OOC. Don't read if you dislike that. Content warning. Also, this is a labor of love, so please don't give me writing advice! Theme: Long live friendship
