MTL - Billion Technology Crystal System - Chapter 12 : Leaving dimly.

Damian, a Centurion of the Punishment Unit of the Baroque Kingdom. “Damn it.” Just once. If I were given just one more chance… ‘I would have truly conquered the battlefield with these guys.’ At the age of 30, he closed his eyes on a nameless battlefield. But when he opened them, he found himself back 17 years in the past. And this time, he had a perfectly functioning mana core that could wield magic. ‘This time.’ I will rise higher than anyone else. I won’t be swept away by the turbulent times. ‘I will conquer.’ Damian, who has returned to the past, wields his spear toward the world.

Just before being summoned to another world, the protagonist’s summoning medium was secretly swapped by someone. As a result, he was not summoned as the “Holy King” but instead as the “Sex King.”The magic he can use includes water magic in the form of lotion, fire magic as candle wax, and his summoned beasts include a wooden horse used for punishment…Branded as “vulgar,” “useless,” and “filthy,” he is rejected, has his engagement annulled, and is ultimately exiled. However, the one who picks him up is a princess from a nation where the sex industry is legal.Using his modern knowledge, the protagonist begins rebuilding the nearly bankrupt sex kingdom. He introduces new fashion trends unknown to this medieval world and uses his authority as the Sex King to subjugate the girls. He then establishes modern sex service techniques.The protagonist's method of leveling up is through intimacy with his heroines (his concubine maids). The more intimate he gets, the stronger he becomes, and the wealthier the kingdom grows.However, the surrounding great powers will not stand idly by and allow a flourishing nation full of women. Thus, the flames of war are ignited.Utilizing his creativity, adaptability, and cunning, the protagonist repurposes his sex-related magic for military applications and overwhelms his enemies.As he gradually awakens to the path of conquest, he begins walking the road of a ruthless emperor. However, by his side is always a heroine, a celestial beauty who keeps his heart from straying too far…

Abandoned at birth in a humble stable, Shirone was raised by commoners—but he was anything but ordinary. Blessed with remarkable insight, he taught himself to read at a young age. A fateful visit to the city introduced him to the wonders of magic, igniting an unshakable dream of becoming a mage. Yet, beneath the city's dazzling facade lurked a ruthless social hierarchy, where power and privilege crushed those who dared to rise above their station. As Shirone uncovers the world's darkest secrets before even coming of age, one question remains—can he defy fate and claim his destiny as a mage in a world determined to keep him down?

Shen Yaowei was an idiot her entire life, and was finally sent to death by the person she trusted the most. After being reborn, Shen Yaowei was no longer silly. She just wanted to cling to the future tyrant and live a life of luxury. Possessing almighty skills and being known as a foolish girl, Shen Yaowei pretended to be an idiot and went on a killing spree, abusing the scumbag until he cried for his mommy and daddy. Anyone who stopped her from clinging onto the tyrant would have to die. Soon, everyone discovered that the frightening Prince Li, who had always been a loner, had changed. There was always a small shadow following behind him. “Ninth Uncle… I don’t have the strength to walk. I want you to carry me…”

the little shadow spread her arms towards His Highness, looking pitiful. “Yaoyao, I’m strong so I’ll carry you!” her elder brother, leader of the martial arts alliance, arrived at the battlefield instantly. “No, I’m stronger! I’ll do it!” her second brother, a miracle doctor, came forward. Then her third brother, fourth brother, fifth brother… All the bigshots had arrived, asking for hugs and to let them carry her. “All of you, get lost! That’s my darling daughter, so I’ll carry her!” Her father, a great general protecting the country, rushed as fast as possible to Shao Yaowei’s front, only to find that the aloof, noble and peerless prince had already knelt with his back facing Shao Yaowei. “Come on, Yaoyao. I’ll carry you.”
