I Have Signed in the Sect for Ten Years, and I Am Invincible When I Leave the Mountain.

After traveling through time and becoming a handyman disciple, Lu Chen was assigned to guard the forbidden area in the back mountain. Everyone thought he was useless. But he didn't panic because he had a sign-in system. Sign in every day and it will be unbreakable. Once you sign in, it lasts for ten years. Ten years later, the ninth-level foundation cultivation, heaven-level skills, and high-grade spiritual weapons were all obtained. Just as he was about to go out of the mountain and sweep across all directions, the seal of the forbidden area suddenly shattered, and a broken sword rose into the sky. There was a female sword fairy in white from three thousand years ago sealed in the sword. What's even more outrageous is that she told him that she kept the system, signed in to help her unblock it, and the Boundless Realm Pill he just took was also hers. Lu Chen looked at the smiling and beautiful remnant soul in front of him and fell into deep thought. So in the past ten years, who has been working for whom? —— [Traditional Fantasy + Sign-in Flow + System + Female Sword Fairy] Completed "xxxx", your character is guaranteed, feel free to read it!
