I recommend the following two novels to you. They are both fantasy or martial arts novels about teams ~ "Myriad Worlds Adventurer Team": The main character forms a team to explore the endless world together. There were different types of people in the team: low magic, high magic, and modern people. There were many worlds in this book, and the story was rich and dizzying. "Greatsword Eastbound": I think this book meets your requirements very well. It mainly talks about the relationship and teamwork between the four people. Although everyone had different standpoints and pursuits, they were still able to unite and fight together under the same goal.
