I Entered The Lost Tomb and Became Zhang Haiqi's Younger Sister?

[Tomb-Raiding Notes fanfiction + original female lead + many original elements + OOC warning]

When Ye Zhiyu woke up, her mind was blank, and she felt completely lost. She stared in bewilderment at the woman crouching in front of her with a warm smile.

Zhang Haiqi felt the girl’s bones, then coaxed and cajoled her into coming home. “I found you, so from now on you can be my little sister.”

“If you can’t remember your past, then forget it all. From now on, you’ll take my surname. I’ll call you Zhang Haiyu.”

Zhang Hailou thought he’d never see Ye Zhiyu again in this life. Then, while accompanying Zhang Haixia to southern Xinjiang to find their master, he spotted a familiar figure. Before he could even feel happy, their master introduced her: “This is your aunt. Come on, say hello to your aunt.”

Wait, how did she become their aunt after just a few years apart??

Later, Ye Zhiyu regained her memories and discovered she was surrounded by members of the Zhang family, a clan of tomb raiders. She’d finally gotten into university and changed her surroundings, so why were tomb raiders still turning up everywhere?

Wu Xie: We’re the closest, right, junior?

Zhang Qiling: You... seem familiar.

The Fatty: Little Yu, don’t worry. Your Fatty here will look after you.

Black Glasses: Didn’t expect me to still be alive, did you?

Huo Xiuxiu: Big Sister Yu, don’t forget me. Come visit me in Beijing often!

Xie Yuchen: Little Yu, tell me if you’re short on money.

[Warning: BL fans, please don’t read this, I’m begging you. Unless something unexpected happens, this is an all-male-leads romance with a female lead.]
