MTL - Final Redemption - ~ Advance 1 book-"Infinite Scarlet".

Birth rates are decreasing. Hope is vanishing. The world has gone gray.Humanity, drifting in quiet collapse, receives an email.Every person on Earth. Simultaneously.The Aegis Mandate.Disguised as a cosmic aptitude test, it triggers The Incident of Separation—a global psychic cataclysm that erases identities, wipes memories, and divides all survivors into three factions: Law, Neutral, and Chaos. Overnight, cities become battlegrounds. Apartments become dungeons. Ordinary people become monsters—or the ones who hunt them.Ragnar Vhagar was just a loner university student. Now, thanks to a system he didn’t ask for, he’s a newly minted Demon King, locked in a crumbling apartment with goblins under his sofa and a glowing soul crystal next to his frozen peas. His new job? Build a deadly domain, defend it from invading “Heroes,” and somehow level up fast enough to not die.Alongside him is Isabelle Thorne, a razor-sharp warrior of few words and one very sharp sword. Their reluctant alliance, born in blood and snark, evolves into trust—and maybe something dangerously close to affection—as they rise together through the layers of the game-like world they’re trapped in.With each conquered domain and defeated boss, Ragnar realizes the truth: the dungeons aren’t meant to crown a winner. They’re meant to break the players. The Law faction wants control. The Chaos faction craves destruction. But Ragnar? He wants something they’re all too afraid to say out loud:Freedom.In the ruins of Kanta’s ogre stronghold, Ragnar and his misfit warband take their biggest step yet—claiming a kingdom, unifying a fractured system, and preparing for what comes next. The Heroes are watching. The gods are stirring. The world is watching a war.And somewhere deep beneath it all... Ragnar is rewriting the rules.

The Emperor of the Great Qi Kingdom was looking forward to a princess, but he had twenty-eight sons in a row!

The tyrant opened the altar and prayed that as long as he gave birth to a daughter, he promised that he would not commit murder in the future and bring peace to the world! Unexpectedly, God really agreed!

Ten months later, Gu Nuo’er, the only little princess in Daqi, was born with a koi carp.

In the face of being surrounded by treacherous officials, the enemy country is staring at the tiger, and the disadvantaged start of man-made disasters and natural disasters——

The little princess waved her little hand, indicating that the baby is not afraid!

Relying on the luck of the koi carp, help the tyrant father to clean up the court situation, please the queens in the harem, and bring blessings to the people around him.

Gradually, she became everyone’s petite baby.

Tyrant Daddy: “The Dragon Chair is my Nuobao’s shaker, as long as she speaks, the world will give it to her!”

Brothers of the prince: “If you have looks and you have money, I just don’t get married, and I spend my whole life to spoil my sister!”

Ministers and uncles: “Who dares to bully the little princess, don’t blame us for besieging and killing them all!”

When Nuonuo grew up, everyone realized that the boy who grew up with the princess wanted to steal her for a long time——

Ye Siming: “Nuo Nuo, whoever makes you cry, I will make the whole family restless, and whoever hurts you, I will take his life. If you like it, my life is yours too.”
