[Ding!] [The Milf Hunting System is online] [Seducing and conquering older women would be made possible with this system] [Isn’t that exciting host?] This was the notification Jay received after dying and transmigrating into the body of a 17-year-old boy named Ryan. He considered life to be meaningless and boring while he was still on earth. Then he died in an unexpected way after getting hit by a truck. Thinking that was his end, he was completely wrong. After meeting with a certain god, he got transmigrated into a world where powers, magical beasts, and so on exist. But things would be different in this world, life wouldn’t be that boring anymore because he has a task now...seducing and conquering milfs. Armed with the milf hunting system, he’d be able to conquer a lot of milfs, benefit from conquering them, and become stronger in the process. Follow him through his journey...

Many islands dotted the vast oceans of this world. However, some of the islands were a lot more sinister than the rest. Those islands, known as Nightmare Islands, were true nightmares to all but the strongest and most fortunate. Children were kidnapped and thrown on these isolated islands by the Nightmare Palace, forced to sign soul pacts with evil soul pets: Nightmares. These devils slowly devoured the souls of their trainers to grow stronger. If the children did not cultivate fast enough, their souls will be devoured whole, leaving only an empty husk behind.

Chu Mu, the protagonist, was an heir to the Chu Clan, but due to a plotted murder, he was thrown on the island, sentencing him to almost certain death. Dancing on the edge of life and death, he struggled to survive with a small Moonlight Fox he captured. When he finally escaped the devilish foremen on his island, he couldn’t help but let a breath out. But little does he know, the experience was only a beginning to a fated journey with his little Moonlight Fox…
