My Wife Turns Out to be an Empress of the Dynasty

This book is also known as 'Because I Spoiled My Wife Too Much, I Was Forced to Become an Invincible Antagonist.'
Gu Lan transcended into a fantasy novel as a supporting scholar.
He even gained a beautiful and delicate wife.
He had initially planned to live quietly, avoiding all kinds of trouble based on the original plot, and spending his life peacefully with his beloved wife.
But he happened to acquire the 'Read and Copy Books System'!
As long as he read and copied books, he could extract cultivation, becoming a saint and even a deity!
Due to being overly invincible, Gu Lan casually crushed major antagonists when he ventured outside. Sons and daughters of fortune were eager to acknowledge him!
As his strength skyrocketed, his career went surprisingly smoothly as well.
One day, Gu Lan, the top scholar from the high school examination, entered the palace and saw a stunning empress behind the curtain, who looked very familiar!
"Babe?"
"Darling, don't you not recognize me when I put on the dragon robe?"
"..."
From that day on, the whole world knew about this extraordinary couple.
The original male protagonist: "He's already a Heavenly Emperor, and I'm just at the third stage of martial power. How am I going to compete?"
