The supporting character's harem is very normal - Chapter 514: Lathel and Rakka

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

Qin Fan was reincarnated and dumped by the school beauty.She had no idea that in his previous life, he was a god of the stock market. His net worth was more than 10 billion, and he could weather any financial storm.In his previous life, he did not care for his younger sister and caused her to fall ill and be hospitalized. Therefore, the heavens gave him a chance to make up for his previous regret. Now, he only wanted to make his younger sister a princess!In this life, it was not enough for him to have a 10 billion net worth. Even 100 billion was nothing.He wanted to create the Qin’s First Group and make it the top capital consortium in the world.

Tang Zhen transmigrated to an apocalyptic world, where humans struggled to survive in various buildings that they built because the ground was covered in lethal dangers that were invisible to the naked eye. Tang Zhen transmigrated along with his mutated cell phone that was packed with miraculous applications.

There were all kinds of cities – some could fly in the sky, some could submerge into the ocean while some could become invisible – and shocking secrets were hidden within them.

The power of Tang Zhen’s city was…

He established a city and quickly leveled up his army with speeding tools. Then, he dominated this alternate world by seizing other cities.

He sat at the very top. Beneath his feet was a vast floating city guarded by dragons and surrounded by angels. Countless cannons were also set up at various corners of the city.

A million miles ahead, in the depths of the ocean, there was another city as large as a continent awaiting his conquest.

Leon was a robotics engineer with a bright future—until he was run over by a military truck and killed on the spot. But death wasn’t the end. Thanks to a cosmic glitch and to an idiot, Leon wakes up in a new world, reincarnated as the son of a minor noble family guarding the wild frontier of a massive Empire. With his intact mind, enhanced brain, and a world begging for progress, Leon sees opportunity everywhere—one that he will grab for sure.But not everything will go smoothly. Monsters come over in the winter, the Empire monopolizes magic and technology, and society clings to barbaric ways. Refusing to accept the status quo, Leon decides to reshape his family’s backwater territory into a land he would enjoy living in. Armed with knowledge from his old life, modern problem-solving, and an irreverent attitude, he plans to revolutionize his territory. But in a land where magic is rare and unknown to ordinary people, he knows he’ll need more than blueprints to succeed. He will need his own wizards and witches...Hey-ho! Welcome! I thought I need to add some information to those who want to know if they should just skip it or not: First, I ain't planning to introduce world-changing, thought-provoking ideas here. It is all for the plain and simple reason of having some fun. What you need to be aware of if you need more details:- Yes, this is an isekai story. No, there are no 'cheats' or systems involved with gaining skills. He is just a guy reincarnating with a gene-modified brain, so it explains why he can remember things and be smart. That is it. Think of it as him having a perfect memory. If you perceive confidence as arrogance, you may very well dislike the MC right off the bat. He is not someone who will lay low and try to blend in when his territory is the most backward and abandoned place in a vast Empire. Where the throne is so far away, messages take months to go back and forth.- The story mostly focuses on kingdom-building stuff and slice-of-life elements, not on conquest or curb stomping others. The main conflict will be centered around wars, yes, but it won't be one guy vs. the world or something like that. Magic is going to play a big role in building up the territory, as I plan to branch out into magic technology later on. I am going to rely heavily on magic because I am mostly a fantasy writer and not an engineer.- The MC's main goal is to enjoy himself. This also means girls. So there will be a harem. Those who are familiar with my works, how I do groups, and how my characters act will know I don't like doing cardboard cutouts of characters. Most of my stories have more than one character accompanying the MC. The same will be true here, with the extra caveat that they will also be involved romantically with the MC. - The story plays out in a 1st person POV. There won't be jumping around multiple POVs; I don't like that. Only when the story requires it and the MC can’t be present by himself for some story parts.- Don't take this story seriously nor look for scientifically 100% real and codex-like solutions for problems. This is a fantasy world, a totally different culture, and with history, that is NOT OUR world! There is magic here, and the MC has a supercomputer for a brain. I think that says it all. - My main goal is to enjoy writing some whacky but real-sounding scenarios. They will be based upon feasible ideas, but I am not writing a damned textbook about thermodynamics. Laws will be bent and broken when the story needs it.- Regarding smut, there are some chapters with erotic scenes, but not every other chapter. So expect it when the mood is there in the story and not because I must cram as much snu-snu in as possible... That won't happen.- No guns. Why? Every similar story has guns. This doesn't. This has mechs and power swords. Why? Because I said so.
