"Uncle, you pressed my hair!" When Lin Yu woke up, he found that he had traveled to the game world and became a royal son-in-law who only cared about having fun. Not only was his heart damaged, he was also targeted by the Holy Girl of the Demon Sect! He even became the inner demon of the BOSS Empress! As a son-in-law, he saves the Xia Kingdom, turns the tide, and helps the building to collapse! After going through hardships and dangers, he became a fairy in this mortal world! Many years later, a maid from a palace came to Lin Yu's window and said eagerly: "Sir, Your Majesty may have caught a cold and your body is very hot. Please go and have a look!" Lin Yu was startled when he heard this. He was already at the extreme level of martial arts and could feel the cold! Could it be that he is addicted to inner demons again and cannot extricate himself?
