Sixty: Senior Military Officers Are Secretly Scientific Research Bosses

(Travel + Space + No CP + Strong Female) Wei Wei, an interstellar mecha designer, encountered an enemy attack and traveled from the interstellar era to China in 1963. When he opened his eyes, he was in the body of a five-year-old girl named Wei Wei. It seems like time travel, but what's weird about it? We encountered a major crisis at the beginning, but now in this small body is Wei Wei from the interstellar, who is looking for death... (PS: the heroine comes from the interstellar, not the 21st century or the local rebirth!!! Because the main storyline is longer, from the 1960s to the reform and opening up, the heroine is set at a young age. She has a secret military identity. The scientific research focuses on gaining a foothold and having a certain amount of power to protect herself. She is cold-hearted, not easy to talk to, and values ​​​​interests.)
