The Midnight Melody quest in the Rock Kingdom mobile game is an extremely challenging task, where players have to fight mysterious monsters, unlock some hidden areas, and ultimately uncover a deeply buried secret. Today, I will talk about the Midnight Melody quest in the Rock Kingdom world, providing you with a detailed guide to help you complete the task successfully and reap rich rewards.

Players need to accept the Midnight Melody quest from the mission log and head to Peter Avenue to find a key character, Edward. Under Edward's guidance, you will learn the initial information of the task and receive instructions to go to the Wisdom Publishing House to look for President Morelak. President Morelak will provide you with some important clues and ask you to go to the sewers on Peter Avenue.

After entering the sewer, you will encounter the Liquid Rhino, which is a level 6 enemy. The Liquid Rhino may seem like an unremarkable monster, but its attacks should not be underestimated. After defeating the Liquid Rhino, you can enter deeper areas. Next, you will meet the Crystal Dog, also a level 6 enemy. After winning the battle, click on the crystal ball behind the Crystal Dog to trigger a new plot and learn the clue about the harp. To find the harp, you need to go to the entrance of the laboratory, click on the stone wall ahead, perform two operations, and the stone wall will gradually move aside, revealing the dimly lit entrance to the laboratory.

Upon entering the laboratory, you will see the harp trapped by a time seal of a tree clock. You need to adjust the hands of the tree clock to point to the correct time. After completing this operation, the seal on the harp will be lifted, and Demon Ding will appear. Defeat Demon Ding, and then a man in black will suddenly show up. The man in black is the final enemy in this mission, possessing a level 35 Ancient Clock Snake as a pet. After defeating the Ancient Clock Snake, the man in black will be forced to flee, and the battle will temporarily come to an end. Players need to play the music according to the rhythm indicated by the sheet music. Upon completion, the mission will be finished, and you will receive a Small Growth Fruit.

This concludes all the content of the Midnight Melody quest in the Rock Kingdom world. After completing this task, players will gain a deeper understanding of the game and be able to improve their gaming skills, taking on even stronger enemies.
