Symbiosis - Xingheyuan
At the end of the 21st century, under the covert control of two extraterrestrial civilizations, human development has stagnated and fallen into a capricious war...... Our protagonist is a smart and lovely science and engineering girl who joins the rebel army out of love and betrays because of hatred, but is inadvertently drawn into the whirlpool of history...... Other characters played different roles in different eras, but all ended up being part of the changing times.
It incorporates some of his own assumptions about future wars and weapons, as well as speculations about the relationship between civilizations in the universe.
I hope you like it ^_^
