Validating the reliability of the information provided from the future was most crucial for Leo.
Unless it was proven to be true, he couldn't blindly accept it.
Ouroboros lowered his head.
He understood Leo's concern.
If he was in the latter's shoes, he would have thought the same.
You couldn't blindly trust a stranger, especially when they were speaking of things that were beyond the norm.
Leo's reaction was quite normal.
He was actually expecting this to happen, and he had prepared a response beforehand.
However, whether it would work or not was up to fate.
"I can't clear your suspicions, Lord." Ouroboros replied, "However, I can give you a reason to believe me. I obtained the knowledge from my future self. He had lost everything. I have seen it. And now he had received a chance to undo everything, save everyone. Think about it yourself. How could he joke about it?"
