"Depict a vivid battle scene with the map of Bangladesh as the background

"Depict a vivid battle scene with the map of Bangladesh as the background. On one side, a group of creatures including a wolf, a hyena, a vampire, and other monsters are advancing to destroy a specific target. On the other side, brave students are standing in defense, holding the Bangladesh flag. The scene should convey an atmosphere of full-scale war, showing the intense clash between dark forces and the young defenders, with the map of Bangladesh symbolizing the entire battleground."
