Immortal Gate Trial: I Carry the Empress with Black Tech (61 episodes)

Xu Yan, an Earth science and engineering PhD, transmigrates to the Xuanhuang Realm, only to have his Heavenly Spiritual Root stolen by Elder's son Zhao Zhe and junior sister Jiang Li, reducing him to a lowly chore servant. Three years later, the Upper Realm initiates a grand trial: passing yields boundless rewards, but failure means the total annihilation of Xuanhuang Realm. Xu Yan is chosen alongside mighty figures like Daoist masters, an Empress, the Holy Son of Mount Shu, and his nemeses Zhao Zhe and Jiang Li. Upon entering, Xu Yan is stunned to find that passing hinges entirely on modern Earth science. Leveraging black tech, he leaves cultivation powerhouses utterly flabbergasted, claims the ultimate Realm Lord Token, and wins the Empress's heart along the way.
