Eldorado

馬力和收養家庭一同到南美洲尋找他的父母，由於亞馬遜河流域非常大，他們打算從上游的秘魯找起。

因為一隻鸚鵡的提示，他們上到馬丘比丘，在那裏找到了一個赤陶圓盤，加上採藥人給的線索，綁架馬力父母的人呼之欲出。他們是誰？既然地球已經被解救了，為什麼還不放走人質？難道與傳說中的黃金國有關？

這是B杜一系列懸疑探險小說中的第二部，內容曲折離奇、險象環生，讀完像經歷了一場奇妙之旅，適合各個年齡層的讀者閱讀。

Ma Li and his adoptive family went to South America to find his real parents. Since the Amazon river is so long, they planned to start from Peru, the source of the Amazon River.

Thanks to a parrot, they climbed to Machu Picchu, where they came across a terracotta plate. Later, aided by a local herb gatherer, they discovered the identity of Ma Li's parents' kidnappers.  Even though the Earth had now been rescued, why would they still not let the hostages free? Was it to do with Eldorado?

This is the second in a series of adventure novels by B Du. Suitable for all ages.
