My Bathroom Leads to the Immortal Realm

Xu Yan unexpectedly gains the ability to travel back and forth between two worlds. In the cultivation realm, he relies on modern technology—utilizing firearms, artillery, cutting-edge gadgets, and contemporary ideals to carve his path through every obstacle. Along the way, he earns a colorful array of monikers: the Scrupulous Cultivator, the Master of a Hundred Poisons, the Thunder Lord, the Bane of Evil Cultivators, the Liberator of Mortals, and the Cultivation World's Sternest Father. Meanwhile, in the modern world, he uses methods and secrets brought back from the immortal realm to radically overhaul contemporary technology, driving forward rapid societal and scientific advancement. Revered as the founder of cultivation technology, the pioneer of a new aerospace era, and the recipient of the nation's highest medal of honor, he is hailed by the people as the Grand Thunder Sovereign of Dual-Realm Inspection, Demon Extermination, and State Protection.
