The unlucky protagonist was hit by a meteorite or annihilated by ashes just after he became an immortal. This is unscientific.
When he woke up again, 'Saab' found himself reborn in the world of pirates, and he immediately made a major discovery.
"The overlord's domineering energy is not just a divine attack!"
"Devil Fruit, it turns out to be the Fruit of Heaven!"
"Luffy, what do you think is the only weakness of espers?"
"I know about Saab. He came into contact with seawater, right?"
"That's right!" Sabo curled his lips and said, "Since there are weaknesses, shouldn't they be overcome?"
"Yes!"
"In that case, then go into the sea!"
