1. the final edit of: Mystery of Whispering Forest

The story follows four friends—Sara, Yuki, Chuq, and Ella—who are on vacation at a holiday park. They discover that Agent Jansen, a forest ranger and the husband of the park owner, has gone missing. The friends decide to investigate the "Whispering Forest," where they find strange, glowing stones and truck tracks, leading them to believe that Agent Jansen’s disappearance is linked to a secret, large-scale illegal mining operation. Their investigation leads them to Mo, a park employee who seems to be a key player but is afraid. Mo gives them a coded message from the missing agent before he is arrested, which deepens the mystery. Through their cleverness and with the help of Detective Ady, the children uncover the shocking truth: the ringleader of the criminal operation is Mrs. Jansen, Agent Jansen’s own wife. The children eventually find a bunker where Agent Jansen is being held captive and brainwashed with the strange minerals. The story concludes with a final confrontation where the friends and the police stop Mrs. Jansen's plan and save Agent Jansen. They prove that courage, friendship, and intelligence are the strongest weapons against evil.
