These plants... they're digesting the bodies of those fish!
When the "Emperor" looked into Trian, he also finally noticed this detail that sent chills down his spine. The massive creatures that had fallen from the "sky" had all become nutrients for the plants. Huge fish bones were situated around the Holy Temple, making him feel as if he was in a graveyard.
And this was Trian's true purpose!
"Retreat, she is no longer an opponent you can handle,"
The suggestion from the woman in the "Emperor's" mind reappeared, only this time mixed with helplessness and frustration.
This made him pause.
It was the first time he had received an order to retreat since he had transplanted his cyborg body.
"You should heed her advice."
Trian also offered the same suggestion as the voice in his mind, "You are not His target. The true enemy is still out there. You still have a chance to survive if you leave now."
