Su Qingyuan, the top interstellar sentinel, was seriously injured during a high-risk mission. When she woke up from a deep sleep, she found that she was bound to the interstellar single mother system and had a pair of twins. In the interstellar era, single parents suffered discrimination. Her ex-husband, a noble, abandoned her mother and son for power. Her enemies secretly coveted her Sentinel genes. System tasks revolve around raising, guarding, and rebuilding strongholds. Taking care of cubs, collecting interstellar materials, and cultivating exotic beasts can unlock the Sentinel's high-level combat power. While she carefully raised two sensitive cubs and taught them to protect themselves, she also cleaned up interstellar predators and exposed her ex-husband's collusion with interstellar rebels. The strongest sentinel in the past lost his coldness and used maternal love as armor to protect his children and rebuild the civilian interstellar base that was destroyed by the war.
