Everyone Knows I'm the Reincarnation of Long Aotian

1. After transmigrating, Xie Ao found himself in the body of the emperor's least favored son. Faced with this classic power-fantasy transmigration setup, Xie Ao didn't panic at all. He followed the usual overpowered-hero playbook, doing everything he was supposed to and making the most of his modern knowledge. Under the name of a friend of the author, he brought classic works into this world. Poems, lyrics, and essays became household names and spread throughout the land; He manufactured glass, soap, and cement, refined coarse salt, and amassed a fortune so vast it could rival a nation; He developed a smallpox vaccine and used modern methods to treat epidemics, greatly reducing the death toll; He improved weapons and gunpowder, trained special forces, and once defeated a million-man enemy army with a force of only a few hundred... Yet for all his abilities, Xie Ao couldn't read people's hearts. His achievements gradually overshadowed the emperor's, until there were no more honors left to bestow. People even began saying that everyone knew Prince An, but no one knew the emperor. The emperor grew suspicious, and the princes fought for the throne. In the end, father and son turned against each other, and brothers became enemies. He escaped the trap his father and elder brother had laid together, only to die at the hands of his own mother. At that moment, he gave up struggling. He died with his eyes open. 2. Xie Ao never expected to transmigrate again, and this time into the body of another prince. This time, he had learned his lesson. He would stop standing out and settle down to live as a carefree loafer. But he didn't know that, during a high fever, the Imperial Preceptor had divined that he was Prince An reincarnated. Fearing his soul might not be stable, the emperor decided to keep the truth from his son for the time being. Posterity knew that Prince An was a genius, but died because the emperor grew suspicious of him. The emperor, the crown prince, and the other princes all breathed a sigh of relief: With such a genius, Heaven blesses Great Yan! But things gradually started to go wrong. When asked to write, Xie Ao left out strokes and wrote like a dog scratching on the ground. Xie Ao said with complete conviction: Writing is just really hard. The crown prince stared at him in disbelief: Nonsense! Prince An could recognize people as soon as he was born, and knew every character by the time he was one! When ordered to lead troops, Xie Ao squeezed his eyes shut: I can't. Your son can't stand the sight of blood. The emperor tilted his head: ? Weren't you the one who trained the Changqing Army? When asked to recite essays, Xie Ao said he was too foolish, and had never studied poetry or prose. The other princes hesitated: You can't even recite the essays you wrote yourself? Besides, Prince An had many friends back then, all of them learned men who refused to enter public life. It was only because Prince An retold their poems and classics that so many of them were passed down to the world. The crown prince stared at his younger brother, who could barely recite two or three lines without making mistakes, his pupils shaking with shock: Back then, Prince An could recite and retell even long, obscure scriptures without getting a single word wrong! The emperor noticed it too. No matter what he asked his son to do, the boy would refuse and make excuses: I can't do it. Why not let Crown Prince Brother handle it instead? The crown prince: *sighs.jpg* How could he explain to Little Seventh that although both families were royal, their family wasn't anything like that other one?! This is the story of the male lead of a serious political-intrigue novel transmigrating into a sweet romance. Theme: Believe in love
