The Persopolis Knight found the hidden door through which the previous 'person' entered the inverted conical building, and then he climbed in.
During the first ten minutes of his entry, he was able to communicate continuously with Ivita and others. But after ten minutes, his voice disappeared.
While Ivita and others were waiting outside the inverted conical building, they looked around and surprisingly discovered the wreck of a stranded ship deep in the dense forest.
Ivita pointed to the depths of the forest about ten meters away and said, "Look, isn't that a ship's bow over there?"
The female ranger, Seville, immediately ran over. After a thorough inspection, she shouted to Ivita, "Yes, sir. It appears to be the bow of a Caravel ship like ours."
"But this is in the center of the island, how could a sunk ship end up here."
She looked around, and then said, "No."
"There are many shipwrecks here, and even pirate flags."
