How can you rule the world if I'm just a substitute for you?

Special forces soldier Lin Xuan has now transmigrated to the Great Qian Dynasty and become the crown prince's stand-in.

The Crown Prince, wanting Lin Xuan to take the punishment for him, said, "Since the Crown Princess is idle anyway, you can take care of her for me."

Lin Xuan smiled calmly: "Bah! What Crown Princess? That's my Empress!"

At first, the emperor wanted to use Lin Xuan to weaken the influence of the imperial relatives, but things went increasingly wrong.

Emperor Qian: "Crown Prince, are your six motorized regiments really here in the capital to celebrate my birthday?"

Crown Princess: "Lin Xuan, my best friend is your person, and even her sister-in-law..."

Lin Xuan put his hands in his pockets. The Northern Di princess is heavily pregnant and wants me to give her a proper title!

What should I do? It's urgent!
