[SPOILERS]
Just caught up to the latest (chapter 641) It’s definitely worth the read, politics, kingdom building, and segssss. But the Earth arcs are just painfully bland just like what other people said. You can just skip ahead the earth arcs and just skim through the last few paragraphs. The next chapters after the Earth arcs summarizes them anyway. And the matters of Earth aren’t related since its ALL faked by Louie, and the matters of San Soleil are separate so it won’t really affect your reading experience. Earth arcs are just XP farms for Louie.
