My Dungeon Life: Rise of the Slave Harem - Chapter 155

I lived my whole life as a s*ave, bound by a leash. But there was one thing that I was able to choose for myself: the place where I would die.“…Any last words?”My only friend asked me in a calm voice, and I quietly replied as I closed my eyes.“Waaaah!”…Waaaah?To cut to the chase, I was reincarnated. And not just as anyone, but as my friend’s youngest grandson. So, what am I going to do now? Well, what else can I do?“I’m going to cause chaos.”

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?

After a year of relentless effort, Alex becomes the first to conquer a tutorial quest deemed impossible by the entire playerbase of Endless Leveling Online. But instead of loot or leaderboard fame, he earns something far stranger—an invitation from the God of Games.His prize? A one-way trip to Arcana, a living, breathing world where stories shape reality—and a chance to become the Protagonist of his own story.In a land of endless possibilities and ever-shifting destinies, Alex would try to bend the rules, rewrite fates, and forge his own legend. But being the Protagonist means more than glory.It carries a heavy responsibility.As secrets unravel and alliances are tested, Alex must decide whom he must protect, and save before the world collapses under the weight of its own story.

I originally thought this was a world like an ordinary urban novel…Drawing comics by myself, traveling is pretty good.
