"New System Announcement: The new system has 2 gods: 1. God of Story (author), 2. God of Observers (readers). So, both the author and readers can give items to the MC. The author provides items for the plot's progression, while readers must meet a qualification based on how many 'stones' they have given to send items to the MC. Let's set it at 50 stones (low-tier item), 100 stones (mid-tier item), 200 stones (high-tier item). Alternatively, you can give tips for an item."
Perhaps many readers are not happy with this system change, but I'm doing this to test out a new system concept that I plan to use in the future. Instead of creating a new fanfic and dividing my focus, it's better for me to continue it in this fanfic so that the fanfic can also keep progressing. The system gets an upgrade here, so there's no nerf. As for the storyline changes, it's only the removal of the training plot.
Regarding the pregnancy plot, someone asked about it. So, the pregnancy plot involving the MC's consorts will take place in Arc 3, and there will be news about the birth of the MC's successors. I've already answered in the comments, but perhaps they didn't read it, and this counts as a spoiler. Actually, there was a dark plot where Lucretia poisoned 3 out of 4 of the MC's consorts during an event they held—Ilithyia, Aemilia, and Domitia would die poisoned by Lucretia, and Lucretia would die at Glaber's hands. This dark plot was originally written for when the MC returned from the battlefield, and I thought it would be quite emotional for the MC. However, because readers don't like dark plots, I changed it. So, the main point is that all of the MC's children will be born, and their births will be written about in Arc 3.
