After the holidays, DAMPFWALZE, MÜCKE, OTTOKAR, STREHLAU and STEPHAN are reunited. But what is the Chinese businessman WANG doing at the castle? The COUNT, who had an accident with his airship, is in debt to him. If the Count is unable to pay the one million euros for the airship within two weeks, the castle will become Wang's property. The boys look for a treasure that could save the situation and strike it rich: the very first Gutenberg Bible. But Wang does not want to hear of it. Before he can resort to hard measures, the children are sitting high up in the old yew tree. Suddenly, Wang's daughter also joins them. Stephan's plea, that the yew is the soul of Shiverstone Castle and its roots do not allow it to be exported to China, changes Wang's mind and he takes the Bible in compensation for the debt.
