Han Fei didn't know if there were rainforests in this world, but the woods like the Deep-Sea Jungle were the main source of oxygen here.
When there was more oxygen, the body size of creatures tended to go bigger. Han Fei had found that the creatures here were multiple times bigger and stronger than their counterparts in other places.
At this point, the situation was obvious. Tremendous amounts of seaweeds were floating along the current like a green undersea carpet, but the carpet was a dangerous one. Apart from anything else, the hundreds of sea urchins on the carpet were terrifying enough.
An explosion burst out a thousand meters away. Everybody saw a ball being shot at them by something. It turned out to be a Dragon-Head Fish a couple of meters long, and it was chasing the ball with its sharp teeth.
Zhang Xuanyu asked in amazement, "Isn't this place very dangerous? Why is this Dragon-Head Fish playing with a ball?"
