The Lovelorn Male Side Character Is My Dad, and the Immortal Lord Is the Rich Family’s Cherished Darling

【Two male leads, toddler boy + System + revered ancestor + doted-on child】 When Sword Venerable Jiang Xuanqing of the Xuanyun Sect ascended, he was struck dead by a bolt of heavenly lightning as wide as a washbasin. When he opened his eyes again, he had become a two-and-a-half-year-old toddler and was bound to a System that ordered him to save a devoted male supporting character. Otherwise, it would kill his disciple. He had only one precious disciple. What a vicious scheme! For his disciple's safety, Jiang Xuanqing was forced to obey the System and cling to the lovesick supporting character, calling him Dad. Sheng Minglou, the male supporting character, is a catalyst for the romance between the male and female leads, the heroine's emotional dumping ground, backup choice, and lovesick puppy. Because of something the heroine says, he picks a fight with the villain. In the end, his company goes bankrupt and he is left paralyzed, spending the rest of his life in bed. For his little disciple's life, Jiang Xuanqing decisively grabbed his leg. “Dad, this venerable one is your son.” “Now that you have me, why bother with the heroine? I quite enjoy being your backup choice. Have some dignity.” Sheng Minglou: ...I'm going anyway! Jiang Xuanqing: “I'll break your legs!” Sheng Minglou: I'll sneak off! Jiang Xuanqing: “Where's this venerable one's eighty-meter broadsword? Chop him up!” Sheng Minglou: ...I'm not going. Jiang Xuanqing gave a cold snort around his baby bottle. If words wouldn't work, he'd use force. A devoted male supporting character? Hmph. Who was the one wearing an apron and washing baby bottles? As for his little disciple... Jiang Xuanqing glanced at the little one in his arms, wailing at the top of his lungs. He held out the bottle. “Here, drink your milk. N-no crying, okay~”
