Defeat the smugglers and enter the slums, talk to the lucky lady in the slums, talk to the people in the orphanage, and pretend to be a nun to go to the church to save the one-eyed commander. Only then can you enter the BOSS camp in the sewer. Remember to use the crystal to save the princess and return to the castle from the secret passage after the fight.
After completing the princess plot and receiving the reward, you can enter the bee forest and the abandoned temple, and go to the lush tower to fight the flower demon.
After finishing the pyramids and abandoned temples, you can go to the Amazon jungle, but at this time I still haven't found a way to enter the Witch Academy.
