What is the second trial?

Liu Feng passed the entrance to find himself in a large room with a bed, and some snacks.

"Wow, I really need to know how they did this. This could be really helpful in the future. Maybe I should ask the old man after I finish the trials. So old fashioned."

He fell on the bed, and just went half a foot in. The bed was soft like a true bed of feathers, and Liu Feng fell asleep within the next minute.

"BEEP BEEP"

Liu Feng suddenly came awake.He looked around for the sudden noise when he say a flying alarm clock with wings on its back. It had a parchment unfolded saying,

"Liu Feng is summoned for his second trial. Please touch the alarm clock for the required transportation."

Liu Feng complied and touched the alarm clock. He warped from his current position to out in the sea. Liu Feng looked around. He saw no one. He waited. He looked out in the open sea. He saw the beach in its all encompassing glory. He looked around to confirm that no one had arrived yet and he went to the beach. He took a stroll on the ocean line, treading on the water. He looked at the horizon and sighed. His time at Dicain flashed by his eyes.

"What am I even thinking about now? Concentrate on the trial. Why didn't anyone arrive right now? Well let's just sit down and see."

Liu Feng sat down near a few trees that he found. He lay down below the shade and closed his eyes.

Five hours later,

Liu Feng opened his eyes. All he could see was the blue sky and the leaves of the palm tree. He got up and stretched. He thought back to himself,

"They said this was a test of perseverance and will power. I was prepared to get tortured but what is happening here? Maybe I need to go into the ocean. There were many elements so maybe the test proctor is a spirit of water."

Liu Feng stepped into the water, and his entire body felt a slight chill course through his veins. He kept going forward, slowly getting accustomed to the cold. He then went underwater with his eyes open, well aware that his eyes would hurt… until they didn't. Liu Feng was shocked when he could see underwater quite clearly and more importantly, he could breathe.

"It must be because I am a soul right now", he thought to himself.

He swam into the depths, but he could feel the temperature decreasing. As he went further in, he started seeing the first signs of moving life. He saw fish and whales swimming peacefully, as if they did not even notice him. He even saw a shark approach him. He tried to get away, but the sharks were too fast. They dove at him, and then all he saw was black.

"Did I die? I pushed it didn't I. I blew the second chance I got."

Then a bright light shined on Liu Feng, and he saw himself back on the beach.

"What happened? I thought I died. What should I do now? I think I should go back to the ocean, but what if I die again?"Multiple thoughts bombarded Liu Feng's mind.

In the end, he decided that the reward was well worth the risk, and he dove back into the ocean. He went all the way to the whales and fish again. This time he carefully swam to the side of the whale. Even if a shark approached him, it would be distracted by the whale right? The shark did not. This did not even look like a shark on closer look. It had blue streaks on its fins, and had glowing eyes.It just passed through the whale between them and went straight for him.
