[Dual male protagonists + double cleansing + cultivating immortals + wearing books + system + He + upgrade flow]
Gu Sheng, a college student, accidentally entered the world of cultivating immortals. He originally wanted to keep a low profile and live quietly to practice, but he accidentally saved a passerby who was in trouble and was bound to the mission system of cultivating immortals out of thin air.
After experiencing the dangers of the world, Gu Sheng could only immerse himself in completing tasks and steadily upgrade, but how could the passerby who accompanied him day and night and was considerate in everything be an ordinary NPC?
He is actually the ultimate villain in the original work who scares the three worlds!
Gu Sheng was stunned on the spot. He pried off the villain's hand wrapped around his waist, and was puzzled - how could the rumored bloodthirsty and cold-blooded demon become his exclusive follower who would never leave him?
