Taken aboard the ship, Tao is soon joined by his faithful friend Pichu; but the bird is also caught, in exchange for Tao's cooperation. Going back to the fort, Ambrosius tries to justify his actions, and albeit furious, Tao agrees to not starve himself.
At the village, the three sailors work on hiding the children up in the trees before the Order of the Hourglass comes to abduct them. Esteban, Zia, Indali and Gunjan come back and tell them about Tao's capture. At nightfall, they make a plan to try to save the children's parents, Tao and Athanaos from the fort; they'll take a river way going under the fort, that Sancho and Pedro discovered in the monkey cave.
At the fort, Ambrosius leads Tao to his underground lab to persuade him to join the Order of the Hourglass. He explains that the Order has been founded by Athanaos, Doctor Laguerra and himself to explore the world, find the Cities of Gold and unearth the secrets of the people of Mu, Tao's ancestors. While he hesitates, Tao gets to read the engravings stolen by Helvetius in the Memorial Temple and hides a screwdriver in his sleeve before being locked up for the night. He frees himself and finds the room where Athanaos is kept. There, Esteban's father tasks him with getting Pichu to send a message to Mendoza.
That night, Esteban, Zia and Gunjan go into the cave and discover the underground river.
But in the jungle, Laguerra and the Rajah's guards come towards the children's village.
