I believe I can give you the answer.
Please make sure that your game character level has reached level 41 before choosing to teleport the game character to the square walk in front of the Balai Building.
After arriving at this location, you will meet an NPC named "The Woman by the Streetlight".
After starting a conversation with this NPC, the system will automatically start the task chain of the task "Don't get lost in the night" for you.
Next, you need to go deeper into the underground level and look for a child named "The Child of the Shadow" at the emergency exit to the right of the Plaza Walk.
After talking to the child, you need to exit through the door next to him/her and go to where the statue is.
Under the stairs to the right of the statue you will find a creature called Black Bomb, talk to it.
According to the mission instructions, you need to go to the statue to pick up an alarm clock.
After successfully picking it up, the system will automatically trigger the plot, allowing you to successfully complete the task.
