LitRPG: Empress Wants To Marry Me

Jiang Su was surprised when he woke up in an unfamiliar room. He then realized that he had taken over the body of a direct descendant from the Heaven Awaken World’s royal family. 
They shared the same name a surname but this Jiang Su was considered trash because he had no spiritual roots. 
This was a cultivation world where the strong were respected. Without spiritual roots, one couldn’t cultivate advanced martial arts. 
Although Jiang Su’s strength was low but his looks were high. All women who saw him couldn’t help but fall in love. 
Even the empress of the Demonic sect went against all objections and captured him to become her husband.
 Which made Jiang Su a target for elimination by those against their union. 
Luckily for him, he suddenly awakened the Mystic God System which will grant him enough power to stand tall in this world and make the beautiful empress fully submit to him.
