Married To The Devil's Son - Chapter 246: 123:

In the dawn of existence, the cosmos was a silent, empty canvas until the Mighty Celestial breathed life into the void, scattering seeds of creation across stars and planets. But from the shadows emerged the Anti-Life Entity—a ravenous parasite, the inverse of all design, consuming every living thing in its path.To protect the last bastion of life, Earth, the Constellar Entities, rulers of the grand design, were dispatched. These powerful beings, accustomed to cosmic command, found themselves with an “unacceptable” mission: guarding humanity. Among them, Triangulum, weary of this mundane task, plots his reincarnation. He has amassed forbidden knowledge, weaving a spell to shatter Earth's protective shield, inviting the very forces they were sent to repel.Yet, every move is anticipated by Orion, the Constellars' master strategist. Though they cannot wield their true power without a human conduit, Orion chooses Xerxez as his mortal vessel. Together, they confront Triangulum's dark magic, but the threat deepens when Xerxez's own son, Maximus, becomes the unwilling host for Draco, the Constellars' most formidable foe.Now, Xerxez faces an impossible choice: how can he defeat a cosmic evil when it wears the face of his own son?

One day, Lu En, a ghost-backed master, appeared in front of Luffy who was shouting to go to sea, and made Luffy cry on the spot.

Luffy: “The pirates in the sea are all monsters like my brother? I don’t want to go out to sea!”

Garp: “For a long time, the two boys, Long and Luffy, with small arms and calves, I really doubt that they are not my sons and grandsons. Like Lu En, they are the grandsons of the old man!”

Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”
