Richard ‘Ric’ modern-day military General dies in an accident and awakens in the body of a poor conscript in the collapsing Starlight Dynasty, a kingdom ravaged by famine, corruption, and endless war. On the very day he arrives, a royal decree is announced: “Every man drafted into the army must choose a wife before deployment to preserve the bloodline of the kingdom.” But because the war has lasted for years, countless women have been abandoned, widowed, or labeled “undesirable.” Most men choose young and healthy women, leaving the rest to starvation or slavery. While others fight over beauty, Ric notices three women sitting silently in the corner: a cold former noblewoman accused of bringing misfortune, a quiet village healer rejected for her frail body, and a fierce chained bandit girl awaiting execution. Mocked by everyone around him, Ric shocks the entire registration hall by choosing all three as his wives. The moment he does [Dynasty Survival System Activated]

A strange explosion in the middle of a park granted me with a bold new power- THE ABILITY TO SUMMON A MECHA TO FIGHT WITH! But that's not all, because the first time I equipped my mecha I felt a strange connection spring into being and now... the bigger I make my harem, the stronger I make my mecha!

They tagged me trash unworthy of a legend's legacy. So I became the devil seated on the throne. ****** They called his father a saint. And called him a disgrace. Theon Dravorn is eighteen, powerless, and hated. On the day he demands his father’s legacy from the archmage who stole it, he’s branded ungrateful and cast into the Netherworld Spirit-Devouring Wasteland to die. He doesn’t. The ASTRAL VILLAIN SYSTEM binds to his blood. It promised strength, demanded evil, and bred scorn. Each mission feeds his power with hatred, resentment, and blood. Refuse, and it kills him. Obey, and he becomes the demon his father died fighting. Now Theon learns the truth: Ren Dravorn didn’t fall as a martyr. He was murdered. And the killers wear halos in the Celestial Realm. To avenge a saint, Theon must become a monster. The only question is how much of his soul he’ll burn to get there?

In my former life, I was a female healer, unaware of the true extent of my powers. My abilities caught the attention of an S-rank guild, and I was recruited with promises of prestige and respect. But instead of the honour I was promised, I was met with betrayal and cruelty. They saw me not as a person but as a tool to be used and discarded. I endured unspeakable suffering—raped,abused, exploited, and left to die when they no longer had use for me. But fate granted me a second chance. [Ding!] For enduring so much suffering until death, you have awakened the Pleasure system. You will be reincarnated into a new body. Would you desire any changes? I was reincarnated as a boy, this time gifted with the power to manipulate time and a pleasure system. As my abilities awakened, so too did the memories of my past life. The pain, the humiliation, and the injustice—it all came flooding back. This time, I vowed, and things would be different. I would not be a victim again. I would rise above the cruelty of my past and claim the power and respect I was denied. Yet, revenge is not my sole purpose. I will become the strongest, the richest, and the most influential figure in this world. I will amass power not just for vengeance but to ensure that no one can ever take advantage of me. As I ascend to the pinnacle of strength and wealth, I will claim what was once denied to me: control, respect, money, and the loyalty of those who once sought to destroy me.
