The end of the earth is coming, the alien "hive fleet" invades, and the Photon Nation sends the strongest lion team to rescue. The seven princes of Emperor Guang each had their own agendas, and the fourth prince Shui Jiancai colluded with foreign enemies in an attempt to usurp power.
Xu Yufan, whose parents died when he was young, was raised by his sister. After returning from joining the army, he struggled to survive with his nephew Xiaobao in the ruins of Jindu City. During her escape, she was accidentally involved in a genetic conspiracy across the galaxy. She also discovered clues to the "Nightingale Disappearance Case" in an abandoned supermarket and basement, gradually uncovering the connection between prehistoric humans on Earth and the bloodline of the Empress of the Photon Kingdom.
The seventh prince of the Photon Kingdom, Shui Jianrui, relied on his mother Lin's scientific research legacy and his own talent to grow into the captain of the Lion Army. From her mother's scientific research notes, she learned that the "bloodline of the empress" in the earth's genes can restrain parasites, and Xu Yufan is a descendant of the royal family. In an accident, Xu Yufan rescued Shui Jianrui, and the two created quantum resonance with the blue-purple stone through the communication chip, and began to work together to fight against foreign enemies. Xu Yufan suffered fatal radiation when he blew up an alien energy base, and his body functions severely declined.
After arriving at the Photon Country Water Polo, even though Shui Jianrui exhausted cutting-edge medical technology, her injuries could not be cured. Xu Yufan, who was pregnant with quadruplets, ventured into the "Stardust Reshaping Pool" in order to gain a healthy body. After giving birth, she was successfully reshaped, awakening the full potential of the Empress' bloodline. However, Xu Yufan was set up by someone at the celebration banquet and missed the public acquaintance with Shui Jianrui, choosing to live a low-key life. After many twists and turns, Shui Jianrui saw through the conspiracy and found Xu Yufan. The two finally overcame many difficulties and confirmed their intentions. Their daughter became the successor of the Photon Kingdom and jointly guarded the future of the two civilizations.
