The supporting character's harem is very normal - Chapter 523: The battle!

Alzi had a promising future. At seventeen, the Goddesses blessed her with a life affinity—a rarity for commoners in a small village; a few days before the class-choosing ceremony, her Mother gets sick. After using her little mana to keep her alive, she runs to the capital to find a true healer. With no money, she sells herself into slavery for a decade. The decade is almost up, but she has been turned into a broodmare for the nobles and faces a sale to keep her enslavement going.

Xu Ping'an was overjoyed to marry, but what welcomed him was a deception.Eight years of devotion, eight years of infatuation, only to be repaid by the one he loved plucking his spine and devouring his bloodline.“You take my spine, I'll turn my Thunder Sword into bone, defy the heavens to change my fate, and awaken the memories of the Immortal Emperor from a past life.”In this life, I will make all those who betrayed me descend into Hell!

In 2077, the gods sent potential successors across the cosmos to Earth for the God Trial. The result: the apocalypse and the rise of history’s most unlikely Harem God candidate.

Leon Traxler was a sociopath that faked his emotions and had a phobia of using women for sexual desires. Yet he chose the power to build an overpowered harem because finding strong, loyal companions during the apocalypse was unlikely.

It was a calculated decision, but he got something he hadn’t bargained for.

Emotions.

With a power that leveled him up through emotional milestones and a system that made him feel them for members, he quickly amassed power and decided that the apocalypse was a blast.

Driven by a desire to make his violent yanderes happy, a love for animal ears on women, and a narcissistic wet dream to be the only man on earth, he decided to partake in the God Trial.

His strategy? To raise an army of women, build a city for his harem, and start a cultured civilization that would naturally end when he died.

Join Leon as he becomes a celebrity on god social media, rises to power on earth, and lives life as a playboy in the apocalypse.

He was The Greatest Talent in the Nine Hells Realm.

Shen Zhenyi began to practice his sword when he was four years and two months old.

At the age of seven, he studied the Ten Thousand Sword Sutra. By the age of eleven, he fought against the Yudao in Shangqing Palace. In an instant, he unleashed one hundred and eighty-five sword strikes, making it impossible for anyone to retaliate. The Yudao admitted defeat and deemed him as “The Peerless Genius.”

At the age of 14, Shen Zhenyi, with his Six Forms of the Ancient Sword, surpassed the swordsman Zuo Tianxing who was ranked among the top ten masters in the world, and won the title of “The First Swordsman of the Abyss.”

He now lies crippled. A fraction of the state he was in before. Or so they thought.
