Tomb Raiding: My Cold and Cunning Buddy

The Grave Robbers' Chronicles fan fiction:

The female lead, Lan Ci, is the young head of the secluded Lan family, a top-tier clan whose power surpasses that of the Nine Families, the Wang family, and all other worldly forces. The Lan family commands the orthodox arts of heaven and earth...

Lan Ci was betrothed to Zhang Qiling of the Zhang family as a child. The moment she takes over as family head, she receives the marriage contract and keepsake from the previous head and descends the mountain. She seeks Zhang Qiling, protects him, and, above all, changes his fate and the tragic destiny of everyone around him.

At first, Zhang Qiling merely doesn't mind Lan Ci. Then he falls for her, quietly and without realizing it... Later, he gets jealous and clingy... The aloof, handsome man he once was becomes a scheming, sweet-talking, white-skinned tangyuan with a black sesame filling...

Zhang Qiling: "Why?"

Lan Ci: "Because it's you. Because you deserve it..."

When the blood corpse appears, Lan Ci steps in front of Zhang Qiling. "No outsider will lay a finger on my man."
