The supporting character's harem is very normal - Chapter 328 Thank you, Akna.

He is high above, the mysterious and terrible King of the Wild. With one glance, he can see people’s romances. He hates women to the extreme, but at his first glance of her, he dotes on her and spoils her.
She is a humble transmigrator, a miracle doctor who doesn’t care for the many handsome men around her. She only wants to become strong, to be worthy of that god-like man. But when she’s finally sure of her feelings, she finds out she’s already been married for years…
……
When wronged：
She uses strength to hit the big handsome iceberg-like man in front of her eyes. “People say that I’m not good enough for you, but it is you who is an old cow eating tender grass!”
A man seizes the main point and laughs like an evildoer. “This husband has to eat the grass to confirm if it is tender or not!” He puts out the red candle……
……
The world says：
The barbarian king has no heart and has no passion.
A pregnant woman very miserably thinks,” If he has no passion, then who is responsible for this big belly?”

The tombs of the gods have appeared in the world!

Zhao Yelan was born as a criminal s*ave and was rescued by the Third Prince. After years of painstaking efforts to put him on the throne, Zhao Yelan became a sycophantic minister whom everyone detested, but he was actually given a marriage by that person to general Yan Mingting, the lone star of Tiansha.

The general caused the death of his father, his mother, his wife, and his dog. Everyone hoped that the general would kill Zhao Yelan as soon as possible.

On the wedding night, Zhao Yelan, who was dressed in red, took out a dagger, his eyes sharp: “What do you want?”

Yan Mingting held his hand tightly, and borrowed his dagger to carve a large character on the head of the bed – – Early.

“You’re weak and frail, get up early every day and practice horse stance with me!”

“?”

The common people thought this marriage was truly wonderful!

They heard that this big minister was beaten every day. He had to repair the roof tiles when the house leaked and also work in the kitchen. He served his husband and was very obedient, and from then on, he didn’t dare condemn people.

Hey, the general was truly mighty!

Zhao Yelan sat lazily by the bed, playing with the dagger, and raised the ends of his eyes slightly: “Where did these rumors come from?”

“From my dog’s mouth.” Yan Mingting, who was in horse stance, patted his thigh. “Madam, please take the seat of honor. You don’t have to get up early tomorrow.”

How is it salvation?

Harems destroy worlds! Preventing a harem will save them!

. . . .

Ok, prevent harems. After seeing the entire system introduction, the corners of Ye Zhizhou’s mouth twitched. In order to return home safely, he decisively began his risky journey—he’d just treat it as if he was playing a large-scale strategy game.

Since then, the people the protagonist would rescue, he rescued first.The businesses the protagonist would make, he made first. The little brother the protagonist would take in, he took in first. The cliff the protagonist would jump off of, he jumped off of first. The gay s*x the protagonist would have, he’d have. . . . Wait wait, can’t do this one, change it, let me change it.

???: No, you can do this one.

Ye Zhizhou (alarmed): Who’s speaking?

???: Your husband.

Ye Zhizhou: . . . .
