"Oliver..." Isaac looked at the explosion. "So, this is how you wanted to go out? What a showoff."

"I guess I can't let your sacrifice go to waste." Isaac vanished into a glowing particles of green light and appeared inside the explosion. The sea of flames surrounded him with thick black smoke.

However, that didn't bother him because he could still see perfectly around him.

In the middle of the explosion, a charred skeleton was hovering lifelessly, the tips of his fingers slowly starting to have flesh.

"Still alive, hmm." Isaac was impressed by Lucifer's will to stay alive. Oliver's body was already gone, and not even an ash of it would be discovered. He was truly gone.

But Lucifer barely stayed alive.

Isaac stopped before the skeleton and grabbed the skull with his palm. The skeleton was very durable, durable enough to survive that explosion. However, the explosion was nothing compared to his strength.
