Peru - China

His father, Lloque Yupanqui, had always told him that the mountains were sacred and that the legends of the Incas lay dormant within them – and soon Tupac would learn more about his brother Mayta Cápac, who would become the next great Inca.

But before Tupac could say anything, they heard the loud drumming of the Inca guards. A huge, magnificent gold eagle hung over the entrance to the school - the symbol of the Inca. Tupaq Amaru, their teacher, was already standing there and beckoned the three friends over.

After a while they reached the old temple, hidden between tall trees. It looked as if it had been abandoned for many years. On the side of the entrance they saw cords and colorful knots - just like Wiracocha's quipu.

After a while, the river calmed down and the children were able to steer the raft safely to the bank. "That was close!" said Perusina and laughed with relief. "But we made it!"

They set off for Thunder Mountain, and after a while they realized that this was not going to be an easy walk. The path was steep and there were strong winds that tried to throw the friends off balance.
