Altar Awakening: Conquering the Otherworld

I accidentally bound to an alien altar, which forcibly transports me to a desolate otherworld upon falling asleep. To protect myself, I confessed this encounter to the authorities, but initially, no one believed me. Until I presented an exotic device far beyond Earth's technology, which authoritative experts confirmed as a creation of an extraterrestrial civilization, prompting official attention. The state organized a research and exploration team to accompany me across worlds, delving into an abandoned ancient city to excavate ruins and uncover the truth behind the collapse of an ancient civilization due to an uncontrolled forbidden experiment. I gradually mastered the altar's power, established a stable channel between the two worlds, set up a cross-border research outpost, and sheltered survivors from the otherworld.
