Ah, I happen to have a novel that fits the requirements to recommend to you. It's " My Girlfriend Wants to Become Immortal "! This book is both funny and slow to read, and it has thousands of chapters! The main character was a man who became an immortal king in the cultivation world. However, when he traveled back to the modern world, his girlfriend brought him back to a world where cultivation civilization and technological civilization coexisted, and he became a student at Vine Cloud High School. The storyline was based on his daily life and the various strange events in the class. The rhythm was relaxed and lively, but it did not lose the depth of thought and discussion. I hope you will like it!
