the one reincarnated

In the year 2277, humanity had become one of the most powerful species in the galaxy, having colonized 1% of the planets in the Milky Way. However, this rapid growth drew the attention of other advanced species, leading to a devastating war that resulted in the near extinction of humanity. Alden, a highly skilled strategist, dies in this war but finds himself reincarnated 150 years in the past, to a time when humanity is just beginning to colonize planets. Armed with knowledge of the future, Alden sets out to prevent the destruction of humanity in his previous life by building a vast empire that can withstand any threat. Aboard his new vessel "Varenna R54", Alden leads a group of 230,000 crew. They land on a planet that was once inhabited by an advanced alien civilization, which has now died out. Alden sees an opportunity to salvage the alien technology and learn from their mistakes, while also building a new civilization for humanity. With his trusted team, Alden establishes the first city of the new empire, and begins to explore the planet's resources. As the population grows, Alden establishes a centralized government and begins to uncover the secrets of the ancient civilization, hoping to use their knowledge to build a better future for humanity. As Alden's empire expands, he faces challenges from other alien species and internal strife, but his strategic mind and determination to succeed propel him forward. The story follows Alden's journey as he builds a new empire, faces challenges, and uncovers the secrets of the past in his quest to prevent the same fate that befell humanity in his previous life.
