Zheng Yan Hou, Wo De Dizi Cheng Le Nüdi Damotou?!

After years of seclusion, Ye Shen has reached new heights in his cultivation, and he has achieved the immortal body. However! When he stepped out of his sanctum, he was dumbfounded by what he saw. His former top disciple is now an all-powerful empress of her own demonic sect, commanding scores of demonic cultivators who are about to hold a sacrificial ceremony. The second disciple is an infamously bloodthirsty assassin who will kill anyone for the right price… her hands stained with blood. The third disciple is a master of poisons, brewing up bugs and potions that can turn people into her puppets. Ye Shen, who had been sealed away for a hundred years, is most shocked to discover that… his name has been spread across the entire continent, known as the demonic master who inspires fear and loathing in all.
