I Just Became a Great Emperor, Then the System Arrived, So I Retired

Lin Qiuxian transmigrated to a fantasy world ten thousand years ago. Though his talent wasn't particularly impressive, his cautious nature and knack for underhanded tricks made him a great emperor! Just after breaking through to the Great Emperor realm, as he prepared to rule the entire continent, the System arrived and warned him that the continent was full of powerful extraterrestrial fiends. Even the top emperors of the major races were barely clinging to life, so he shouldn't get cocky. Terrified, Lin Qiuxian immediately went into hiding and began working behind the scenes, doing everything he could to keep the world from discovering him. Before disappearing, he adopted a baby girl and raised her as his daughter.
