The Low-Key Sword Saint by Aurelia Vale

Lin Feng learned the price of arrogance with his life. Reborn in the Nine Continents as the supposedly useless senior disciple of the Shenxiao Sword Sect, he makes himself a promise: this time, he will hide his talent, avoid unnecessary trouble, and survive. For a while, the plan works. Then hidden enemies strike his master, and remaining in the shadows is no longer an option. Forced to reveal only a fraction of his ability, Lin Feng overturns everything his fellow disciples thought they knew about him. The sect’s forgotten failure may actually be a peerless sword genius—and every glimpse of his true strength draws more attention than he ever wanted. He only wants a quiet life. Unfortunately, the world seems determined to make him famous.
