Doomsday Lord - Chapter 306:

At the beginning, travel to the Holy Land Mary Joa and become a slave of the dragon people.

With the help of the Tianlong people’s “enthusiasm”, Chenos obtained the Devil Fruit that can rebound everything, won the favor of the Empress, learned to be domineering, and also gained the Golden Emperor as his younger brother.

Finally, in order to thank the Tianlong people for their “enthusiasm”, Chenos, who became the five emperors, decided to let them leave the Holy Land Mary Joa and experience the fun of the world!

[No system, no golden fingers, take the road of developing fruits, practicing physical skills and domineering, hoping to bring you a different world of pirates. ]
