Answer: The entrance above the arena leads directly to the second floor.
1. If you want to enter the Tower of Thieves, you must first go to the church in the middle of Royal Aventurine City. There is a sewer here, and you need to go through the sewer.
2. Explore the sewers for a while, and finally find the upward entrance and reach the arena. There are also tasks you can collect in the arena. After receiving them, continue upward.
3. Go directly to the second floor of the Thieves' Tower. After defeating the gatekeeper, you can start running the map to spawn monsters. This is still very challenging and a good place to hone your skills.
