I'm 90 years old and the system tells me it's time to create harem - Chapter 2: There’s no need for further words. I agree.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

After being sent to another world because of a god's mistake, Lin Fan obtained the ability to...tame?

“What? As long as I raise affection, I can tame anything? Even gods?”

“Could I even make a harem with this power?”

Humanity was living peacefully on Earth for millions and millions of years until the day unknown monsters from beyond space invaded them.

When humans were about to disappear, some people with abilities came out to the light and shared their knowledge and powers with the world, and together, they managed to push back the invaders during a terrible war that had lasted for years.

This war had created many orphans, and among them, Kye had lost everything, even his parents. And the only thing he received from their death was a pale-looking necklace.

However, once the necklace finally activated, a system was given to him, and his life changed completely.

The system gave him quests to do, and Kye complied. He was getting stronger every time he achieved them, until the day it gave him a weird quest.

[You have one day to kill the one who had sinned. If you do not kill, you will die.]

Bai XiaoHu has been a nine-tailed fox since birth and is always proud of her nine big and fluffy tails. However, when she was going through ‘heaven’s test’, the judgmental lightning burned all nine of her tails, leaving her with an empty back.

Bai Xiaohu was shocked, devastated, and raged; she has no choice but to look all over the world trying to find a way to grow her tails back.

Then she suddenly recalled that she once encountered a poor little white kitten several hundred years back, and to help him become enlightened, she offered him fur from each of her nine tails, helping to cultivate him into a nine-tail cat. Since his tails came from hers, if he is willing to give her one tail, she can attach it back to herself!

Thus, she started looking for that nine-tailed cat everywhere, only to find out he isn’t a part of the heavenly court and instead reincarnated into a human and had gone through several lives in the mortal world. In addition, the moral world he is now in is raging evil energy, which will cause it to collapse soon.

As the leader of the No. 1 mercenary team in the ‘last days’, Lu Ye was always respected and feared by everyone up until a little girl joined his team.

The little girl looked quite delicate, but super empowered when beating the zombies. Lu Ye’s only problem is that she keeps staring at his butt.

Couldn’t bear it anymore, Lu Ye cornered the girl: “What are you looking at after all?”

But who would’ve expected the girl to suddenly burst into tears: “Where are your tails?”
