My Dragon-Aotian Junior Disciple Fell to the Demonic Path

After transmigrating into the cultivation world, his character is that of an early-death cannon fodder: the Daoist Sect's most mysterious beauty of a senior brother, rumored to have died in a lovers' quarrel? Yan Bie joins a sect to cultivate the Heartless Sword. One of his teammates is a transmigrated heroine who seems sweet and comforting. She says with a grin, "A Yan can't die. If you die, I'll make the male lead and this whole world die with you." Another teammate is a mysterious guest who seems to be a spy for the demon race. He tilts his head and stares at him. "A flower worth picking should be picked. I'll climb to the cloud peaks for you, and you'll descend into Hell for me. Aren't we a match made in Heaven?" One of his rivals is a young master of a great clan who seems to be his cheap little brother. He blocks his way with a sword. "You're not my brother. We're not related by blood." "..." Stop messing around. This is the overpowered male lead's set. His junior brother is a young version of an overpowered male lead: solitary and gloomy, carrying a blood feud, yet simple and sincere. Every night, he waits for him in the courtyard. They practice swordsmanship together and attend lessons together. By day, he follows him around, watching him from morning to night, afraid something might happen to him. After a joke, he practices smiling over and over, just hoping to make him happy. Passionate and clumsy, cheeks flushed, he stumbles over his words as he asks: "Senior Brother, y-you'll wait for me, won't you?" After Yan Bie fakes his death, he hears that the overpowered male lead has fallen to the demonic path. He has become the Demon Venerable. The Six Realms tremble in fear, and the whole world hunts him. Countless immortal sects pursue and surround him, including his teammates. The young Demon Venerable builds a floating palace in the demon realm. It is made of white jade and filled with countless rare treasures. One end of a chain of thousand-year-old ice is locked around Yan Bie's pale, slender ankle. When it strikes something, it rings like a bell. Yan Bie falls into a deep, hazy sleep, unaware of the world around him. His junior brother kisses his cold, pale knuckles. Tears stream from the corners of his crimson eyes as he slowly takes them into his mouth and licks them. "Senior Brother, countless people love you. I do too." He buries his face in Yan Bie's neck and murmurs hoarsely, "Could you show me some tenderness?"
