The End of the World: I, Start a Demon Castle

The end is coming and the world has fallen. In his previous life, Gu Beichen was betrayed by the "Justice" team, reduced to zombie rations, and died with hatred. After being reborn, he no longer believes in hypocritical humanity! Activate the [Sin Devouring System] at the beginning and bind a demonic castle that can swallow sins and reshape succubi! While other survivors are still struggling to survive for a can, Lu Li's demonic castle has risen from the ground under the nourishment of sin! When the Ice Mountain Sword Goddess who once betrayed him died of exhaustion in battle, he sneered and picked up her warm "Phantom Core": "Your pride and your sword will only be mine from now on!" - In the reincarnation pool, the loyal woman [Fallen Sword Demon] knelt down on one knee and offered his soul and blade! When the green tea school belle who played with people's hearts flirted with him, he judged her mercilessly and made it his own: "Your charm will only bloom for me from now on!" - Under the throne, the charming [Charming Demon Fox] bowed her head and swayed her tail, waiting for orders! I, Gu Beichen, will not be the savior, only the tyrant of the last days! My castle is the final destination of all sins! My harem is the most powerful sword that judges the world! ——Welcome to my devil paradise!
