Kingdom's Bloodline - Chapter 621 Not easy

Le Xia traveled to the Marvel world. He was born ordinary, but after encountering a dilapidated bronze box, his life was destined to be extraordinary.

“Put on the holy clothes and protect the love and justice on the earth!”

The moment he touched the box, these words were imprinted into his soul.

Whether it’s evil spirits in the dark, covets in the starry sky, or “gods” who regard all living beings as playthings, all evils that try to disturb the peace of this land will face the justice of the saints.

When the golden holy clothes reflected the dazzling starlight and the white cloak fluttered without wind, the legend of the Saint Seiya began to spread throughout the Marvel universe.
