The battle above Mary Geoise raged fiercely.
Beneath the ground, unnoticed by anyone, the hard earth of the Red Line churned as though it had turned to liquid.
Several figures hid within it.
Charlotte Linlin, Katakuri, Oven, and Cassius.
The four concealed themselves inside an earth Homie, avoiding the fiercest fighting as they secretly made their way toward the underground prison holding Typhon.
Few people knew Typhon was still alive.
Fewer still would have imagined that the Big Mom Pirates would use the war between the Flying Pirates and the World Government as their chance to infiltrate Mary Geoise and rescue him.
Typhon, the "King of Monsters," was the most terrifying criminal the World Government had imprisoned since its founding.
The fact that they held him in Mary Geoise itself showed how seriously they took him.
Not far away, Typhon sensed familiar presences drawing closer.
A smile crept across his slightly gaunt face.
A hint of color returned to his pale features, and his long-quiet heart began to pound.
He would be out soon. He needed to prepare.
The World Government had built this prison specifically to hold him.
It stood empty, sealed inside and out, with only one way in.
Seastone lined the surrounding walls. Even a Devil Fruit User with an unusual power could not pass through them to enter the prison.
But the Big Mom Pirates had no intention of playing by the rules.
If there was no entrance, they would make one.
So what if Seastone lined the walls? They would smash through it.
"Mama, Typhon's just inside," Cassius said.
His third eye, usually shut, had opened, and an eerie light glimmered deep in its pupil.
Even through the wall, Linlin could sense Typhon. The unmistakable presence of her eldest son's soul left her visibly excited.
