I didn’t get it. So lil flower was trying to kill Ao gu even before he raped him?

That's right. He was angry because Ao Gu accidentally interrupted his concentration when he was still a flower in the bud, enough for the lil flower to lose grip on the energy he had managed to gather until then, which was needed for the lil' flower to evolve into a higher being. Losing that energy meant he couldn't evolve

Ohh thank you!
