Destroy the Senior Brother and Lead the Empress by Ten Realms at the Beginning

Lu Wuyou traveled through the Taixuan Sword Sect in the Canglan Realm and became a sloppy senior brother who was ignorant and drunk all day long. I wanted to be a quiet salted fish, until one day, the beautiful master brought back a cold and arrogant junior sister, Leng Wushuang. Lu Wuyou instantly awakened the [Tiandao Invincible System]. As long as he binds his junior sister, his cultivation level will always be a full ten realms higher than hers! At this time, Leng Wushuang's cultivation was completely useless and he was just a mortal. Lu Wuyou simply had sex on the spot and was promoted to the ultimate "realm of the emperor" in the mortal world! In order to unlock the peerless divine wine in the system mall, Lu Wuyou changed from his usual routine and began to "feed" his junior sister crazily. "Junior sister, use this Nine Turns Divine Pill to eat as a jelly bean." "Junior sister, I'll give you this Emperor's Taoist weapon to chop firewood." … Leng Wushuang was completely confused. She was originally the Empress of the Nine Netherworlds of the Upper Realm, but she had to be reincarnated and rebuilt after being plotted by a traitor. She thought she would suffer all kinds of grievances in the mortal world in this life, but who could tell her why this senior brother who was drunk all day long and was so scary? Is the bath water thrown away carelessly the divine spring of enlightenment? Can a randomly broken branch cut off a fairy sword? Leng Wushuang secretly made up his mind: I must work hard to practice and see through the true face of my senior brother, this hidden true immortal, as soon as possible! Lu Wuyou: Junior sister, stop thinking about it and break through quickly. If you don't break through, how will I become an immortal?
