The supporting character's harem is very normal - Chapter 461 Karol Magic Academy.

“You want to steal my genes then leave?” He grabbed her and tried to force her to hand over the child that was born three years ago.

I woke up in this world with a System and a sword. Without hesitation, I chose to complete the princess’ quest with my weapons: Arrogance. Cunning. Pride. I will lead guild Sol Invictus. Denizens of the 7 hells, respect me. Servants of the 11 heavens, know fear. Guild Invictus, know the suffering of training so you can wrest victory from the jaws of those who dare doubt you.

This is a story about a snake named Tycondrius waking up in a fantasy world of swords and sorcery. There is action, violence, unapologetic murder, and arrogant displays of power. There is an emphasis on combat growth as well as psychological growth on more than a few members of Guild Invictus. There is camaraderie and also the inevitable comedic dialogue amongst manly men. There are even elements of romance and Tycon running away from terrifying, powerful women. (Did you know most female snakes eat their partners after mating?)

Before he was a little over 10 years old, he was the nightmare of the Gorge of Heroes and the headache of countless people that had been abandoned by the world.

After leaving the Gorge of Heroes, he became a legendary figure of the number one academy in the continent, and he alone brought numerous changes to it.

Thereafter he stepped foot onto the continent to become a legend, but the road to become a legend was far more difficult than he’d imagined….

On a continent where puppet masters reign supreme, using anything and everything as weapons: living creatures, shoes, daggers, pendants, clothes, shields, guns — which they call puppets, this is the story of Bai Xiaofei with his trusty sidekick, Huskie, on a quest to find out exactly what happened to his parents and become the greatest illusion stream puppet master the world has ever seen. This is a story of wit, plot twists, love, strategy, cultivation, humor, and the unknown.

Lao Li’s family finally gave birth to a girl! It’s a pity that we are on the road to escape…

Mrs. Li: What should I do? My baby has lumps and no milk to drink!

Jiayin spat out bubbles of saliva and waved her little hands: “Don’t be afraid, I have space, bring your own rations!” then…

Li Laosi: Mom, I picked up a dairy goat on the roadside!

Li Laosi’s wife: Mom, this rabbit hit the tree by itself!

Li Laosan: Mom, I went to fetch water, and the big fish jumped into the bucket!

Li Laosan’s wife: Mom, a handful of rice actually makes a pot of rice!

Mrs. Li’s head was buzzing. With the blessing of her ancestors, she was giving birth to a little lucky girl, who would prosper her family once she was born! As a result, when I turned around, there was a pile of dates, apples and pears on the kang…

Mrs. Li: “Wait a minute! Fu Niu’er, let grandma slow down. We have good things, but we have to take them out slowly!”

Li Jiayin: Hehehe
