Noah didn't feel offended by old Heaven and Earth's words. The similarities that they mentioned referred to his creation and destruction that the rulers shared.
The statement concerning the ghosts actually interested him. Noah didn't know if his desire to prove Heaven and Earth wrong was preventing him from thinking straight, but he couldn't help himself nonetheless.
The group turned toward Robert. For some reason, the orange figure had marked him as the ghosts' counter, and they tried to guess why. Luckily for them, the old rulers explained themselves before they wasted too long.
"His hatred toward us will improve his effectiveness against the ghosts," The orange figure explained.
"What about my hatred?" Steven snorted to express clear annoyance.
"Your feeling is a childish desire for revenge," The figure replied. "It can't compare to an existence reborn to hurt us."
"How much do you even know?" Noah asked as he arched his eyebrows.
