'First of all, congratulations to you who are reading this book. You have become the new demon king... No, maybe you should be silent because it means you have no hope in this life and will die miserably!' Quoting the beginning of the diary of the third demon king. As an ordinary college student, Xu Mo woke up and found that he was already in another world, and was carrying the mission of reviving the demon clan to conquer the world. Looking at the three consecutive devil seniors who had died in despair in the past, Xu Mo sweated a drop of cold sweat on his forehead. The headless knight: 'Master, I am willing to charge for you at the forefront of the battlefield.' The Paladin of the Horse: 'Master, I captured three outsiders who illegally sneaked into the territory while patrolling. According to the laws and regulations of the mainland, the three people have been beheaded.' Seraph: 'Where my wings pass through will be a wasteland. When will you assign me to the expedition?' Xu Mo: 'Don't shout and kill all day long, can't you think of some peaceful means of conquest?!' This describes an ordinary age who can't even beat Slime, and created a great lyrical epic in another world.
