Within two days, Li Du found himself wrong about Hans.
In late April, when the weather was as bright as ever, he set out to sea in the morning, and Hans soon harvested more than a dozen black gold abalone.
The weather was getting colder, and they didn't have much time left to harvest. Abalone season was almost over, so they wanted to do more work while the weather was still good.
Once more, after catching the black gold abalone, Li Du saw Hans sitting on the deck watching him.
"Are you ready to rest? Didn't you just have a rest?" he asked.
"No, I'm waiting for you," said Hans.
"What are you waiting for?" asked Li Du.
He didn't have to take Hans with him to catch the black gold abalone. He could fix the position of the black gold abalone in advance and hang a buoy to mark it.
In this way, the buoy floated on the sea, and Hans only had to follow the line on the buoy to find the black gold abalone.
