Incarnate into the Calamity of All Races, My Name Is Nian

[No heroine + decisive killing + invincible genre + cool writing] Liu Guanyi, who came from time travel, only thought that everything in this world was an NPC. He could kill whenever he wanted and play whenever he wanted. He was unrestrained and uninhibited. He even accidentally awakened the system. As long as it caused a negative impact on the opponent, he could get everything from the opponent. The first thing he did was to beat up the original protagonist Ye Fan. After getting the starting funds, he started to push everything. I don't know how many years later, Wanzu still said in fear that the devil finally stopped killing people. This year has passed.
