My Phone Connects to the Immortal Realm

By chance, he inherits the legacy of an ancient cultivator from the Cultivation World and obtains the Heaven-Peering Mirror. With its energy depleted, the incomplete mirror attaches itself to his phone, allowing him to open a small passage to the Cultivation World. After arriving in Zhongzhou, he is caught up in a struggle for supremacy when relatives of the demonic cultivator Qin come after him.

Combining Earth's technology with the spiritual energy of cultivation, he develops high-risk weapons and crushes his foes with a mechanical nuclear-blast strategy.

He sweeps across the world, eventually claims supremacy, and ascends to the Immortal Realm.
