"There is something in the city that can exterminate us all!" Rhea's body trembled as the gray particles on her body fought with the energy from the blood-red crystals.
Poseidon found those words hard to believe, but he knew she had no reason to lie. Was their strength not even enough to defend themselves against that existence?
"Urgh!" Rhea's face turned pale as she tried to control the corrosion inside her. "There was something wrong with the future I saw. That man could perceive my existence and even attack me. How is it possible for someone in the future to attack someone from the past? Unless..."
Rhea thought of something horrifying but quickly brushed off her guess.
"No! That should be against the very laws of the universe! Not even those from my homeworld can do that thing! But then..."
She looked at Poseidon and said, "My duty is to guide you and not order you. If you still want to take action, then I won't stop you."
