The Peerless Sword Immortal's 3,000-Year Sign-In Behind the Scenes

He had just made a comeback and become the senior disciple, when the Age of Black Fog descended. His sect fell into a land ravaged by demons and monsters. Shen Changge had already finished writing his last letter when he suddenly awakened a sign-in System. [Sign-in successful beneath the Sword God statue. Reward: Great Luo Sword Scripture: Sword-Controlling Chapter] [Sign-in successful at the training grounds. Reward: 500 years of cultivation] [Sign-in successful atop Sword Aura Mountain. Reward: 1 Annihilation Sword Aura] Shen Changge took a laid-back approach to sign-in, only to soon discover that he was invincible! In the Age of Black Fog, demons and monsters ran rampant, and the world seemed shrouded in an impenetrable mist. Killing demons and monsters could disperse the fog and unlock sign-in locations. But before long, Shen Changge discovered that the black fog was not as simple as it seemed! A mysterious and powerful organization of people in the fog, strange teachings transmitted through the black fog, and an overwhelming terror lurking within it that would be drawn to anyone who killed three great demons. Did every sect statue have a purpose of its own? If one was shattered, did that mean the sect had been destroyed? Master the black fog, and you could wield the mysterious art of killing hidden within it! Shen Changge: Cultivation is just too exhausting. You’re a mature System now, so you can cultivate on your own. System, sign in!

I just want to let you know that I’m invincible] [The Age of Black Fog] QQ group: 700740698
