Li Du had to find Steve because of the promise he had made. He carried Elsonʼs hope with him. Also, there was the fact that Peter knew his secret, and perhaps the rest of his companions did too.
He also needed to know about the space-time bugs. After listening to Peter, he had a hunch that if he could find Steve, he might be able to find out the exact identity of these creatures.
Therefore, he cleared an area of the island and encamped there for the time being, but the camp had only supplies and they lived on the other side of the island.
The Island of the Lost was a little suspicious. Li Du decided he did not dare to stay there long. He believed that the warning that the Inuit young man gave him was worth listening to.
There were helicopters and some supplies on the island, and the bodyguards and other supplies were on the shore. Every day they landed on the island to search, then returned to camp at night to rest.
