Protagonist: Tang Daohan (apprentice) and Shen Junwei (master)
Tang Daohan silently fell in love with Shen Junwei in the real world, but his love was humble. He was heartbroken when he learned that Shen Junwei had passed away without expressing his feelings. By chance, he was bound to System 555, came to the world of cultivating immortals, and transformed into the Dark Night Demon Lord who was in opposition to his master. When he completed the mission, he also fell in love with the substitute. He looked very much like Shen Junwei. During a mission, he looked at the person with his back turned and said: Turn around and let me see, is it you?
Intention: Warming up of feelings
