I Just Want to Lie Flat: Saving a Fox Forces Me to Become Invincible

The rating will go up once it comes out!!! [Super sweet + one heroine + System + mutual devotion] Su Mofan died suddenly in his previous life from overwork, then unexpectedly transmigrated to a fantasy world and awakened the golden finger every transmigrator was supposed to have: a System. And he didn’t just get any System, either. He awakened the most powerful, ultimate, unstoppable power-up System. He could have relied on it to dominate the world, but of all things, he was the kind of guy who just wanted to lie flat! “Host, I’m begging you, just do a quest!” the System wailed, clutching his leg. But Su Mofan only replied coolly, “Not doing it.” There was no other reason. After getting a second chance at life, all he wanted was to spend the rest of it in peace. Until one day, a white fox leaped into his arms. The System said she was Su Jiuli, a demon empress capable of destroying the world. So one day, when he woke up and saw a young woman curled up in his arms, he fell into deep thought. “Xiaofan, I want a hug.” “Xiaofan, I want a kiss.” “Xiaofan, let’s get married, okay?” “System! Is this really the demon empress?” he shouted inwardly. But the demon empress’s duty was to lead her people to greatness. Their separation was inevitable, even though neither of them wanted to face it. “Forget me, Xiaofan.” She gazed at him calmly, her eyes full of love and reluctance. In the end, she still left. Her family arranged for her to marry into another powerful clan. On the day of the wedding, someone stopped her bridal sedan. When she lifted the curtain, she saw his handsome, defiant face. “I heard my wife was marrying someone else. I wonder if she got my permission.”
