After the earth has experienced several extreme climate changes, life on the earth tends to become extinct. In order to survive, human beings explore the vast depths of the universe and seek planets where they can survive. During their space roaming, Homo sapiens were exposed to cosmic ray radiation, which induced mutations in secondary sexual characteristics. Three secondary sexual characteristics, alpha, beta, and omega, are derived. With the long migration process, Homo sapiens split into two galaxies. Galaxy X and Milky Way Galaxy. The X galaxy mainly develops technology and civilization, and the Milky Way galaxy mainly develops military affairs. But thirty years ago, Galaxy X was also a galaxy with a strong military. Interstellar pirates attacked. Ji Li from Galaxy X led his troops to fight off the pirates, but they chased them too far and lost contact. Ji Li's lover Nan Chen died of the epidemic just three months after giving birth to Ji Jie. Lu Feng, the president of Galaxy X, ordered Nan Chen's body to be burned. When Ji Li came back from a victorious battle, all that was left of his lover was a handful of ashes and a five-month-old child, Ji Jie. After a series of political struggles, X Galaxy weakened its military and focused on developing technology.
Thirty years later, interstellar pirates attacked again. Galaxy X was unable to resist, so it asked the Milky Way Galaxy for joint operations. The Milky Way galaxy proposed the conditions for technology exchange for combat power. And asked the children of high-ranking officials to marry generals of the Galaxy Alliance.
The top brass of Galaxy X looked down on the Galactic Alliance's bellicose and barbaric behavior, so they pushed Ji Li's son Ji Jie out. Ji Jie proposed a quid pro quo in order to get the current president to agree to legalize mark removal surgery.
In this way, Ji Jie married Qi Ziya, the commander-in-chief of the Ninth Legion of the Galaxy.
