After a Thousand Years in Seclusion, I Emerge Invincible

Synopsis: [Fantasy + Swordsmanship + No System + Ruthless and Decisive + Female Emperor + the Myriad Worlds] Thousands of years ago, there was a Sword Immortal who fought his way through the heavens with nothing but a sword. He slew countless great emperors. His slaughter turned the skies dark and stained rivers with blood. It was that battle across the heavens that made sword cultivators famous. From then on, everyone under heaven knew that Yue Wuya was the greatest swordsman in the Myriad Worlds. He said the immortal realm was too cold and quiet, so he passed down three thousand great paths. He said the immortal realm was too desolate, and he didn't want to be the only one who knew the truth. He also said that only the sword in his hand could save this wretched world. If you ask what is best in this world, It's brothers, swords, and fine wine.
