Begin Your Immortality by Guarding the Demon Prison

In the 532nd year of the Qian Dynasty, the Qingzhou Demon Prison was established to suppress the demon criminals of all generations. In the 1761st year of the Qianlong Period, Lin Mo opened his eyes and began his life as a jailer. Every day in prison, the demonic aura and cold air continued to surge, invading Lin Mo's body. Fortunately, he discovered that as long as he killed the enemy, he could gain martial arts cultivation and perform martial arts deductions. So he held the long sword in his hand and kept slashing, just to restore a peaceful world to the world! Many years later, the Wei Dynasty was completely defeated by demons, and the five states and four prefectures continued to fall. Only the Qingzhou Demon Prison stood quietly in the tide of troubled times. Countless demons and monsters are coming together. Behind the dark clouds, there are palaces and palaces in the sky. Lin Mo points out his sword, and it is precisely through your millions of years of cultivation that I can prove my martial arts immortality!
