He conscientiously played the role of a cold master, ignoring his charming apprentice, drawing his sword to fight the mortal enemy Demon Lord, speaking little to his master, and silent to his senior brother. System: That's great, host, you have played the role of a just and cold master. Now let's find a way to win the heartthrob protagonist! Green is justice! Green is light! When it turns green, we can escape and be free! Pei Jiutang: Why is it so green? System: Play freely! Host, just be happy! Pei Jiutang: Simple. That night he found his mortal enemy, the Demon Lord, and asked, "Let's make a deal. I'll be the Demon Lord, and you'll be He Yan'an's master. How about that?" Demon Lord, one of the suitors of the heartthrob He Yanan, agreed. Pei Jiutang became a demon king who did all kinds of evil. The next day, the whole world knew that Pei Jiutang was crazy. He was the coldest and most righteous person on the right path, but he became a demon. He wanted nothing more, and his master, brothers and disciples all wanted nothing. Later, everyone learned that Pei Jiutang had only abandoned one person, his apprentice He Yanan. Because Pei Jiutang has connections with everyone in the sect, there have been ambiguous scandals with his former senior brother and master for many years. Including a beautiful love story with the former Demon Lord. One day, while Pei Jiutang was doing his job to create a scandal with a faceless flirtation, he met his former apprentice He Yanan. When He Yanan saw him, his eyes immediately turned red, and his hands hung helplessly by his sides, helpless and hesitant: "Master, don't you want me anymore?" Pei Jiutang said nothing, but his heart softened. He acquiesced to He Yan'an's behavior of coming to the demon clan to find him. He would secretly guide He Yan'an in martial arts, and He Yan'an also respected and loved him. "You don't have to come again. I have nothing to teach you." In the past few years, Pei Jiutang has gained enough green points and can leave. He Yanan: "Master, once you are a teacher, you will always be a teacher." Pei Jiutang: "I am not your master, so there is no need to come again. Good and evil are not mutually exclusive. From now on, I will see you once and kill you once." He Yanan secretly clenched his fists. The next day, Pei Jiutang was about to be taken away from time by the system, but the world was in turmoil. The demon king was in chaos and both good and evil were destroyed. The world was in chaos. Pei Jiutang fainted during the battle. When he opened his eyes again, he found that in a closed room, the demon king He Yanan asked him with a smile, his eyes red: "Master, you are not ready to leave me again." Pei Jiutang found that the system had crashed, and went to repair it because the world had collapsed. He couldn't leave. It was best to beg for mercy at this time, but Pei Jiutang didn't know how to do it, so he only asked five words: "Do I want you?" He Yanan stroked Pei Jiutang's cold cheek: "Master, then who do you want? Disciple, here is the marriage proposal letter given to you by the previous demon lord, master, and uncle. Master, who do you choose?" Pei Jiutang: "Let me go out and I will choose." He Yanan: "It's better to say goodbye. My disciple will help Master choose. Master, let's get married now, okay?" Pei Jiutang gritted his teeth and said word by word: "Unbridled." Intention: study hard
