A Tomb-Raiding Journey in Another World

The characters may be out of character... CP: Xiaoge. Don't read if that bothers you.

The lovesick doctor Zhang Yichen transmigrates into the world of Tomb Raiders. The System tells him he is the older brother of Zhang Qiling, the Sacred Infant who has slept for three thousand years. Later, he awakens inside a coffin amid the ruins. Thinking about his past, he can't help smiling slyly.

He later encounters the Iron Triangle while concealing his identity, arousing Zhang Qiling's suspicions even as he seems strangely familiar to him. Gradually, he discovers that he and Xiaoge Zhang Qiling know each other, and their relationship is far from simple. During their adventures, he protects them with reckless acts that inflict a thousand losses on the enemy at the cost of eight hundred to himself. This gradually plants seeds of worry and guilt in the Iron Triangle. Zhang Qiling grows increasingly confused, suspicious, and certain that something about him feels familiar. The System sees it all, but Zhang Yichen is a troublemaking obsessive. Only the System knows his secret...
