Bai Yixing, an ordinary but imaginative young man, accidentally got a clue to the mysterious treasure of the "Phantom Stone", so he summoned his old friend Pang Dun, the cold and mysterious Hong Ling, and the train-talking "Old Liu" to form a four-person adventure group to travel across the Wonderland Continent and embark on a treasure hunting journey. They battled wits and courage along the way, breaking into dense forests, going down mines, trekking through mountains and rivers, exploring ruins, and constantly clashing with the dark exploration group led by the villain Youhu who also coveted the treasure. Along the way, everyone experienced crises, misunderstandings and growth, and also deepened their bonds with each other through laughter. As layers of mysteries are solved, Hongling's past emerges, and the mystery of the treasure gradually becomes clear, culminating in an ultimate showdown between justice and greed, friendship and betrayal. After going through many hardships, everyone not only found the true meaning of the treasure, but also harvested growth and precious memories, and started a new life in the world.
