I'm sorry, I'm just translating this novel and adding the part you suggest would need to change the story a lot.

I completely understand your frustration and I truly appreciate your feedback. As a translator, my ability to expedite or enhance the content heavily relies on the level of support for a particular story. When more people support a story, I dedicate additional time to streamline the pacing and reduce filler content, aiming to deliver a more engaging experience. At this moment, due to limited support for this specific story, I focus primarily on translation. However, I'm committed to improving the quality and pace as support grows. Your input is valuable, and I'm open to suggestions on how I can better enhance the content for supporters like you. Thank you for considering supporting my work!

Thank you so much for your interest in supporting me! Currently, Patreon is the sole platform where I share additional chapters and receive donations. I truly appreciate your willingness to support me in other ways. If there are any other means you'd like to suggest or if there's anything else I can offer, please let me know.

Hello! I very much appreciate your interest and enthusiasm for history. It's great to know that you would like to see a sequel that further explores the protagonist's universe after becoming king of Cintra. For now, my main focus is to continue translating the story so that more people can enjoy it. However, I'm excited to hear that there are people interested in seeing how the plot could expand into a journey through the multiverse and discover more about the connection to Gaunter O'Dimm. If reader response is positive enough and there is continued interest, I had considered continuing the story beyond the original version. Although I must mention that I am not a writer and I only translate and edit small parts of the stories. Therefore, I cannot guarantee how the story will develop in the future, but I will do my best to maintain the essence and quality of the story. Thank you for your support and for finding this story such a rewarding read!
