After Becoming a Scummy Immortal Venerable, I Sacrificed Myself for the Dao

Zhu Jiuxiao transmigrated into a book. He became the cultivation world's number one scumbag, the villainous Immortal Venerable Zhu Jiuxiao, who used a poor, pitiful boy to reach the half-step True Immortal realm, then cruelly abandoned him once he'd achieved his goal. Zhu Jiuxiao was so furious he wrote the author a two-thousand-word bad review. That very night, he became the villainous Immortal Venerable in the book. The first thing he saw upon opening his eyes was a well-behaved young man in front of him, crying, “Immortal Venerable, save me!” Zhu Jiuxiao's heart broke. After rescuing the boy, he treasured him so much he was afraid to drop him or let him melt in his mouth. He gave him a name and magical artifacts, and even promised to make arrangements for him after his own death. He had no idea he'd mistaken the boy for someone else. The person he'd saved was the original protagonist, the future Demon Venerable who would destroy the world and kill him. The Demon Venerable lost all his cultivation and ended up at the Jiuyu Tower. By acting cute and playing sweet, he managed to get close to the number one figure in the immortal path. Swearing that once he regained his cultivation, the first thing he'd do was kill Zhu Jiuxiao and erase this humiliating past! After Zhu Jiuxiao corrected the plot and rescued the protagonist again, he got a report saying the story had gone off the rails He had no choice but to sacrifice himself for the Dao. Little did he know that after he died, the little Demon Venerable he'd doted on would forcefully take him back to the demon realm and use a forbidden art to try to resurrect him. When Zhu Jiuxiao woke up, he was completely baffled “System, did I fail to sacrifice myself for the Dao?” System: Host successfully sacrificed himself for the Dao.

Zhu Jiuxiao looked at the sleeping Demon Venerable beside him. “So what do I do now?” System: Dear, our recommendation is that you accept your fate~ [Optimistic, possessive Immortal Venerable gong X scheming and fierce Demon Venerable shou] [Two male leads + transmigrate into a book + older top + devoted couple + evenly matched + pure love + mild faked death] The author Wang is still writing sweet romances.
