Find some novels, old books from a few years ago

The first book: It seemed to be a transmigration. There seemed to be such a plot. The protagonist's family or something arranged for him to marry a woman. He said he didn't want it. Later, when he went out for a stroll, he met that woman. Later on, the two fell in love, but they didn't know each other's identity. They didn't know that the other party actually had an engagement with him. The second book: This memory is very vague. It seems to be a transmigration book.(I used to only like to watch transmigration.) I only remember a vague part of the content. It seemed that the main character joined a small team, such as adventurers, mercenaries, or simply a few people forming a small team. Later, it seemed that the main character hid his strength and walked together with them. In the end, this team seemed to participate in some competition or something. They went to a very dangerous place with many other teams. The other teams thought that their team was too weak and would definitely be finished. Later, the main character displayed his strength... He really couldn't remember anything else. Lastly, he was looking for a few books that were similar to the plot of the second book. They were books about hiding one's strength, joining a certain team, and secretly attacking at a critical moment. He also asked for a few more transmigration books where the female protagonist didn't like it, or even hated the main character until she fell in love with the main character in the end. When you answer, please briefly describe the content of the book that corresponds to my conditions. Thank you! Oh, I'm a guy. By the way, I want a fantasy novel with a lot of female leads… Finally, the book I'm looking for is much older than Douluo's book… It seemed to be much earlier than the Grand Master Zhang Sanfeng's trip to the alternate world… I'm not sure about the details, but it seems to be a book from the years when the magic school was popular.
