Uchiha Gen obtained the sacrifice system of the heavens, with a "crit sacrifice" once every ten days.
So:
On the first day, he got Mirror Flowers and Moon.
On the tenth day, he learned the Sixth Form of the Navy.
On the twentieth day, he ate the thunder fruit.
On the thirtieth day, he stood in the Valley of the End and felt that there seemed to be no challenges in this world.
Save the Uchiha? Change the ninja world? Just roll with it.
His eyes had already been cast on the system panel, where the coordinates of the vast world were newly unlocked.
Douluo, Dou Po, mortals...
All heavens and all realms are journeys.
And his legend has just begun.
