Time Travel Brother Killing: Saving the Sword Maiden at the Beginning

If a person is unlucky, he can be struck by lightning while walking on the road. But if you are struck by lightning and travel to a different world, is it bad luck or luck? Bai Yu travels through time to kill, and is bound to the system? Can you become stronger by hanging up? Wait, that swordswoman was knocked unconscious by the goblin and was about to be dragged away! "Stop! You can touch my wife!" So Bai Yu embarked on the path of becoming stronger and saving the world. Many years later, Bai Yu, who became the only adventurer to surpass platinum and reach the diamond level, was living in seclusion in a villa on the border. Sword Saint Girl: "I want to accompany my lover, it doesn't matter if I am a high priest." Bai Yu: "I understand the Sword Saint, but what are you doing here, Miss Counter? The Adventurers Association still needs you! And you, the Witch, don't want your team anymore!" To make up for regrets, the introduction is weak.
