The upper half of the Sea Magic Waterfall was a vast expanse of sea.

The sea was about 270,000 light-years in diameter and 21,000 light-years thick. It was a Star Sector-level behemoth.

More than thirty thousand people who participated in the trial, including the members of the Gu Ding Pirate Crew, were scattered in different parts of the vast sea.

Meanwhile, Gu Ding was in the process of diving rapidly.

"You must increase your current speed by 18% to reach the second layer of this sea in two minutes and escape the storm." Neptune's voice clearly reached Gu Ding's ears.

Gu Ding's legs exerted force again, and his diving speed continued to increase. However, he could clearly feel the pressure coming from all directions.

"The deeper I dive, the greater the resistance I encounter. Moreover, the pressure from all directions is constantly squeezing every cell in my body. I've only dived less than one-third of the way down and I'm already feeling this. Is there really someone who can dive to the bottom of the sea to obtain treasures with cultivation below Heavenly God level? "Gu Ding was not in a hurry. Instead, he asked Neptune with some doubts.

"I've seen the terrain of the Sea Magic Waterfall. Even the physical strength of a low-rank Heavenly God would find it difficult to reach the deepest part of the sea. However, the terrain at the bottom of the sea is not flat all the way. There are cliffs and abysses in some places, and there are lonely peaks that reach into the clouds in others. A few of the peaks are on the second layer of the sea, and there are also treasures on those peaks. However, the range of your spirit detection is affected by the strong force field of this sea. It can only reach a few kilometers, and the deeper you go, the smaller the detection range. In addition, there are very few peaks that reach the second layer of the sea, so very few people can obtain treasures. "

"There's still one thing I don't quite understand. Where did the treasures at the bottom of this sea come from? Could they be left behind by the fallen participants? "Gu Ding continued to ask.

"Do you know how many monsters there are in this sea?" Neptune asked a question in turn.

"I don't know. Could there be hundreds of millions …" Gu Ding guessed with some uncertainty.

"Gu Ding, the number you guessed is a fraction of the actual number," Neptune laughed. The Sea Emperor laughed. "I just did a rough scan. There are more than 800 trillion demon beasts in this sea region."

"What does this have to do with treasures?" Gu Ding asked in confusion.

"The bottom of the sea is where all the dead Demonic Beasts have been buried for a long time. It can also be called the Natural Beast Graveyard. This Bestial Mound has existed for who knows how many eras. The large amount of bones at the bottom of the sea have long crystallized into high-quality energy ores. "

After listening to Neptune's explanation, Gu Ding's eyes lit up. "You mean, this area of the sea is actually a super large mineral vein, and the entire bottom of the sea is covered with energy ores?!"

"You can understand it that way. However, not all the fallen fellows turned into ores. There were also a few extremely powerful existences whose physical bodies were too tough to be eaten by other demonic beasts. Thus, they were preserved. These corpses are excellent materials for making doppelgangers. "

"I'm getting more and more interested in these waters." Gu Ding grinned.

"Hua …"

At that moment, the sound of rushing water from above reached Gu Ding's ears. "A storm is coming?!"

"Don't worry …" Before Neptune could finish his sentence, he heard a "puff" sound.

Gu Ding felt as if he had just pierced through something.

"You've now entered the second layer of the sea. You don't have to worry about the storm anymore," Neptune explained.

"Is this the second layer? It doesn't feel much different from the first layer. "Gu Ding looked around." How are Lili and the others? "

"They're still on the first layer and are rushing toward the second layer. They're also luckier than you. No one encountered a storm, "Neptune said with a smile.

"That's good." Gu Ding looked up at the boundary between the two layers of the sea.

The two layers of the sea were clearly separated. The first layer of the sea looked like a dark blue sky to Gu Ding, who was now in the second layer of the sea.

In the sky above, a huge tornado formed a huge whirlpool in the water. It drove the surrounding seawater to spin at a terrifying speed, swallowing everything around it.

However, the second layer of the sea seemed to have an invisible protective layer that prevented the terrifying whirlpool from invading it.

The whirlpool only circled above Gu Ding's head for a moment before quickly moving away into the distance.

Gu Ding was very surprised to see this strange scene.

"Once you're on this layer, you won't have to worry about the storm anymore. The second level of the sea was not without danger. This level had the highest number of monster beasts. There were countless True God-level monster beasts, and there were even high-rank True God-level monster beasts. It's not completely safe for you, "Neptune immediately reminded when he saw that Gu Ding had let his guard down.

"Hehe, there are many types of monsters, which means there must be some that taste good. Don't forget to remind me if you see any monsters that taste good. After killing them, I can leave them for Biggie to use as ingredients. Biggie will be very happy. "Gu Ding grinned. He was almost drooling.

"Can you think of anything else other than food? The reason this Experience Space exists is for people to train and enhance their strength. Even the treasures here are just rewards that come with the training, "the Sea Emperor reminded again.

"Neptune, you said before that this Experience Space is actually the most suitable for tempering one's body. Is it because of the pressure from the depth of the sea?" Gu Ding was also a cultivation fanatic. As soon as he heard Neptune mention the Experience Space, he immediately raised his doubts.

"I don't know what's below the waterfall, but according to the results of my current exploration of the sea, I have a guess. There are at least three benefits to tempering one's body in this sea. "

"The first is the pressure of the sea that you mentioned. The deeper you go, the stronger the pressure. Moreover, when you reach the third layer of the sea, the speed of the sea is tens of thousands of times faster than the speed of the sea above. The pressure of the pressure on the cells has a very good effect on the tempering of the body. "

"The second is the monsters here. All the Demon Beasts in this sea region were living beings with flesh and blood. Their bodies contained powerful flesh and blood energy. As long as you have the corresponding skills, you can rely on devouring these monsters to strengthen your blood, qi, and body. The creator of this trial space must have left behind this cultivation technique for his descendants. However, for you, you only need to use your Natural Divine Power, Devouring Heaven and Earth. "

"The third point is another special feature of this sea that you may not have noticed. The deeper one went, the lower the temperature became. The temperature of the third layer of the sea is already terrifyingly low. However, in addition to the low temperature, there are several giant volcanoes in this sea that have a temperature ten thousand times higher than the inside of a star. These volcanoes were probably left by the creator of this Experience Space for Heavenly God-level powerhouses to temper their bodies. However, whether it's high or low temperature, it has an excellent effect on the tempering of the body. "

"According to what you said, the waterfall below the sea is probably a more advanced Experience Space." Gu Ding's eyes lit up when he heard Neptune's words. The more challenging something was, the more interested he was.

"Be careful, you're being watched. That guy seems to have a special sense that exceeds the detection range of ordinary people," Neptune suddenly warned.

"Is it a human? I thought it was some monster. I just felt like I was being watched. " Gu Ding actually felt it too, but he thought that he had accidentally trespassed into some kind of monster's territory and was being coveted by the monster. "Why would a human be watching me?"

"Although this is a training ground, there are also many people who came here with the mentality of hunting other humans for spoils of war. After all, those who can pass the screening are all powerful people, and they must have some wealth. Moreover, the mortality rate in this Experience Space is very high. No one knows what's going on inside. "Neptune's explanation was indeed what some of the Trial Takers were thinking.

"If that's the case, let's see who's the prey and who's the hunter." Gu Ding grinned.
