Invincible, I Was Reborn and Transported to a Broken Sword

[System + Rebirth + Upgrade + Combat] Ye Yu, who was invincible on a dark night and a stormy day, began to show off. Suddenly there was thunder in the sky, and Ye Yu was hit in the next second. When he opened his eyes again, he found that he had turned into a broken sword, and a mechanical voice sounded in his mind. He successfully deceived Ye Yu into binding the system through the system's cunning operation. Later, due to a strange combination of circumstances, he was bound to the girl Ye Lu for life and death. Then came the attacks from other sects on Ye Lu's family, and Ye Yu relied on his own abilities to save them one by one. During this process, Ye Yu himself continued to unlock his own strength from his previous life. However, many enemies were made along the way, all of whom were eyeing Ye Yu and others. If you want to survive, you must continue to become stronger. Ye Yu knows this truth well. So he put aside his prejudice against this world to protect Ye Lu and fight his way through this world.
