Demon Lord! Bounded by Zero

Single heroine + protagonist group is invincible + sacrifice The male protagonist's character is cowardly in the early stage, selfish in the middle stage, and self-sacrificial in the later stage. The heroine has been brainwashed by external forces. If you don't like it, don't spray it. In the first few chapters, I recruited people for the protagonist group, which was more of a daily routine. Music skills are used to change your identity in the later stage, and videos are used to gain merit in the later stage. A cat maid is given to you when you open the door? Is this the beginning of happiness or the continuation of nightmare? The battle between demon masters continues from generation to generation, and one day... The demons outside the territory are in turmoil, and the rise and fall of the dynasty depends on the present day! Escape, fight, hold on, resist! Where should the body go? Where should the soul rest? When Luo Mengling stood on the city wall and looked at the millions of troops, she was not sad, but she burst into tears because of those words. The generals are all gone... The dream returns to thousands of years, and the soul returns to its hometown. Thousand years of resentment, when will I repay it! ! ! This is a continuation of the previous war. In the past, the demon lord split himself into two, but the clone tried to raise the flag of rebellion against the main body, and finally ended up dying together. Now that the demon lord's consciousness has awakened, the heirs of both parties have been decided, and it is destined that the demon lords will merge into one. But... Who is the last demon lord? But we still don't know!
