Traveling Through the World of Immortality to Become a Salted Fish

Traveled through the world of immortality at the beginning of the Shehu Period and became a genius? Join the protagonist group, defeat the villains, and strive to get home at the finale. It just took a sudden change, and both of his best friends died. And are they really just trying to stop the war between immortals and demons? "Live well and face this real disaster." The last wish left by a close friend, the sealed land of the Outer Gate Garden, and the familiar... Past in the dream. After all, it's a clichéd plot about capturing villains in time-travel novels. Or is it a plan planned by heaven for you... A century-old situation?
