Ask for a novel name

Please give me the name of a novel. Thank you, big brother.
It was published five years ago, and it was already finished. The last sentence of the novel's introduction was,"Fighting with yourself is endless joy." The main character was a counselor. Just like Inception, he could hypnotize others and enter their dreams. If the main character was injured in the dream, he would suffer the same injuries in reality. The part that he remembered more clearly was that the main character was shot and did not dare to go to the hospital. He was afraid that the hospital would find out that he did not have a gun but had internal injuries caused by bullets entering his body. He would be taken to the hospital for research. There was also a plot where a rich man found the protagonist and asked him to enter a novelist's dream and ask him about the ending of the eunuch's novel.
The main character used a Rubik's cube to determine whether he was in a dream or not.
The villains in the story were a group of men in black. They could also enter other people's dreams and fight with the protagonist. The ending was like this: The protagonist woke up from his chair and realized that he had defeated the man in black a long time ago. Because he did not want to face reality, he hypnotized himself and recreated the process of defeating the man in black. This time, he thought it through and rushed to the airport to thank a beautiful woman in red who had been helping him.
