Between Heaven and Earth: Book Two Lu Delong, half-human, half-yao mercenary, has been training to become more powerful in his quest to be of worth to Cangji, the formidable immortal he desires. To prove he deserves a place in the expedition to Mount Kunlun, Delong risks his life in a dangerous mission against Black Moon Sect. However, as Delong grows stronger, he becomes more aware of the vast disparity between himself and Cangji—ten years is not nearly enough time for Delong to be of much use in the impending conflict that may shake the very foundations of the universe. Yet the realization only fuels his yearning to understand the forgotten mysteries of his connection with Cangji. Delong knows he will never achieve his goal of saving the celestial dragon if he remains mortal. Luckily, thanks to his past he has a shortcut to attaining immortality. However, memories from his previous incarnations deeply disturb Delong, and he soon realizes he might not be the innocent outsider in the conflict between gods as he first imagined himself to be.
