If I Ask You to Practice Swordsmanship Facing a Wall, How Can You Open the Sky with One Sword?

It's hell mode after traveling through time... Ye Xuan's parents died and he had no spiritual roots. After being picked up by his elder brother, he became a female master and found shelter. However, because he was too mediocre, he worked as a kitchen knife in the kitchen for twenty-seven years! Fortunately, he has a late blooming system, and after signing in for ten thousand days, it starts to take off! Ten thousand days of cultivation? Deliver! Heaven level skills? Deliver! A peerless artifact? Deliver! An incredible opportunity? Deliver! Time to get rewarded! Sign in at the location and get a crazy draw! Trigger missions and get great gifts! So cool! … "Ye Xuan, you hold a butcher's knife in your hand, how dare you kill someone? You're going against the grain!" Ye Xuan, "I'm sorry, but I must kill this person. Whoever dares to stop him will kill God if he blocks him, and kills Buddha if he blocks Buddha!" "Kill!" With a sword coming out, all things came to life. The power of this sword caused the sky to be split open. The whole place was silent and shocked. "Disciple, didn't I ask you to face the wall and think about your mistakes, and practice your sword skills by the way? Why did you split the sky with one sword?" "I have retained most of my strength with this sword..." Let's see how Ye Xuan grew from an unknown kitchen chef to a swordsman!
