The hostility from Qin Lan can only be seen as a kind of seasoning in Shen Shi's life now.
However, even if Shen Shi's emotions and regard for human civilization mostly stem from the empathy of being human, a small part also comes from the enjoyment and anticipation of life.
From falling in love, forming a family, nurturing children, to climbing the career ladder, being in the spotlight, even becoming a "big shot" forever remembered in human history.
All these are what make up "life".
Most of this is a future he can no longer achieve after choosing to escape Blue Star and distance himself from human civilization.
So, he can strive for changing the fate of humanity, build magnificent Planet Fortresses, battle alien fleets, and at the same time enjoy luxury and flamboyance, share romantic nights with Ai Xin'Er, and gather familial love with his family.
For everyone's life naturally encompasses both the "big" and the "small".
