The Only Human Observer in the Universe

In the interstellar era, pure human beings have been designated as "inferior species extinct due to internal friction." And I am the last living human being in the universe. I wear bionic cat ears every day and play the weakest and most inconspicuous "observer of extinct species" at the Interstellar Research Institute, listening to this group of genetically fused "new humans" talk about how to nail my civilization to the pillar of shame in history. They laughed at my frailty and called the research in my old paper pile rubbish. I endured it. Until that sudden attack, the precious relics of civilization were about to be destroyed. In the chaos, I only "accidentally" tripped and kicked away the pirate's weapon accurately. Everyone thought it was an accident. Only the silver-winged commander with great military exploits, Ren, focused his scrutinizing eyes on me - this female observer with cat ears who was "trembling" with fear. He saw the flaw. A silent pursuit ensued between the eyes. I must continue to play my role of weakness, ignorance and submission. But in the dark where no one can see, I am quietly making plans. It's time to show these arrogant "gods"—— How do the "ants" who are despised by them use lost ancient martial arts and wisdom beyond the times to shake up the entire interstellar structure and rectify the name of my brilliant civilization...!
