After Coaxing an Old Enemy into a Substitute Demon King

[Screenshot of 2021/05/31] [Completed, please give me five stars (kowtow. JPG)] Sheng Huaizhao passed through the book and became the destined enemy of the protagonist Sword Fairy, the villain Demon Lord who was stabbed to death with a sword in the future. On the first day of traveling through the book, he met the protagonist, his old enemy. The protagonist is still a young man. Because he failed to overcome the tribulation, his spiritual core was completely broken. In order to save his life, Sheng Huaizhao made a major decision—— Give your demon core to the boy and coax him to become the future demon lord. And he uses the broken spirit core to continue his life, and he can be a salted fish with peace of mind. When the young man woke up, he was so angry that he said, "My dear husband, you are finally awake." The weak boy stared at him closely. Sheng Huaizhao: "You have worked hard to practice the devil's way, and I was seriously injured to protect you..." The young man was silent for a long time and held his hand: "Okay, I will protect you." Sheng Huaizhao, who was freed from suffering: Ah, yes, yes. Start to mess up. JPG * The young man has outstanding talent and is also good at practicing magic. It's just... During the day, he was a submissive crybaby, coaxing him to ask for three candied haws. The night was a ruthless iceberg, and Sheng Huaizhao wouldn't even be allowed to get into bed. Sheng Huaizhao: Failed to overcome the tribulation and had a split personality, right? The swordsman prodigy in the original book was taught by him to become a powerful demon king in all directions. On the day of the Three Realms Crusade, Sheng Huaizhao disappeared from the world and there was no news at all. Three major things happened that day: The Demon Lord is invincible and unifies the three realms. The Demon Lord was abandoned by his sweetheart and became completely insane. The demon king wants to betray his beloved with his own hands. * The unfaithful person Sheng Huaizhao did not disappear on purpose. The shattered spiritual core in his body recovered, and he ascended overnight, becoming the new Sword Immortal. He inexplicably becomes the protagonist's nemesis again. Gan. After being captured, Sheng Huaizhao raised his sword: "Your Majesty, the Demon Lord, be safe. I will kill myself immediately without your having to worry!" All the subordinates are looking forward to it. But I saw the young demon lord holding out a child who looked very similar to the Sword Immortal, with beautiful eyes filled with sadness—— "When your father liked me, he called me your little husband. Now he calls me His Highness the Demon Lord." Men:! ! ! Sheng Huaizhao: ... Where did the child come from? ? Reading guide: [I am a cultivator, and I have a private establishment like a mountain] [Shou cannot give birth to a child, but the child is related by blood to Shou~] Intention: To face various difficulties in life with a positive attitude.
