Under normal circumstances, a key could only open one door. However, if the form of the key changed, it could open another door.

What happened to Gu Ding was similar to this.

Originally, there was only one teleportation point for Hell Gate's Death Mode. However, the aftermath of the battle between the twelve-winged angel and the Death Paladin had caused the space-time tunnel to shake, changing Gu Ding's original teleportation route and sending him to a completely different Space-Time Gravel.

Standing on the ground where the plants were as lush as a primitive jungle, Gu Ding felt a little excited. "I thought the destination would be a barren place. I didn't expect the greenery to be so good."

"Gu Ding, don't be careless. This Space-Time Gravel is about twenty times the size of Cerule. There are many beings with extremely powerful auras, and they are not something you can compare to at your current stage." Neptune quickly scouted out the information about the world.

"Are there many powerful beings of true god-level?" Gu Ding could not help but ask.

"Other than true god-level, there's someone even more powerful … I'm guessing it's a Heavenly God. However, the aura of all the creatures in this world is very special. It feels like their cultivation is completely accumulated from the energy of their flesh. "Neptune thought it was a little strange.

"Physical Cultivator? But it can't be that everyone in this world is a Physical Cultivator, right? "Gu Ding was also a little surprised.

Neptune did not explain further. Instead, he directly projected a video. "Look at this."

In the video projection, a creature that looked like a wild boar bit a snake-like creature to death and ate it. After eating, its body began to change. Its body size soared at a speed visible to the naked eye, and in less than three minutes, it had grown by half. Originally two meters long, it had grown to three meters. Not only that, but its height had also increased, and the muscles of its limbs were clearly more developed.

Then, Neptune projected a second video projection.

In the second projection, a group of humanoid creatures dismembered a giant beast that was tens of meters tall and directly ate its flesh raw. After eating, the humanoid creatures' bodies, which were originally more than two meters tall, soared at a speed visible to the naked eye by tens of centimeters. Above their flesh, their muscles were clearly much stronger.

Then, Neptune projected a third and a fourth … Video Projection. Each and every one of the video projections showed the same strange scene. All the creatures directly ate other creatures and then evolved at a speed visible to the naked eye.

"What's going on?" Gu Ding was a little shocked when he saw this. If they followed this method, it would be too easy for the creatures to evolve. All they had to do was keep eating.

"If I'm not wrong, the evolution rule of this world is the same as the evolution of spores. As long as you keep devouring, you can continue to evolve. No wonder there are so many Real Gods in such a small place. Moreover, there are even Celestial Gods. "Neptune scanned around and roughly understood the rules of this world.

"But if we continue to evolve in this manner, won't the entire world perish? A Heavenly God would have to devour countless lives to get there, right? "Gu Ding raised his doubts.

"Take a look at this!" As the Sea Emperor spoke, he projected another image.

In the image was a boundless ocean. Above the ocean, countless dandelion-like lifeforms were floating. Those lifeforms were constantly devouring each other and evolving. In less than half an hour, a dandelion-sized lifeform had evolved into a giant bird that was more than a meter long and began to devour other smaller birds …

In the ocean, countless microorganisms were constantly devouring each other, constantly evolving into dandelion-like lifeforms that left the ocean and floated …

"There are thousands of similar oceans in this world, occupying fifty percent of the entire world's surface area. These oceans are constantly producing microorganisms that devour each other. Then, they evolve into spores that leave the ocean and begin to evolve wildly. The birds that had left the area covered by the ocean had basically completed their initial evolution and become lesser deities. After that, they will continue to devour other lifeforms on land and in the sky to continue to evolve. The number of these microorganisms produced in the ocean every day is comparable to the number of stars in the Cosmic Sea. It is an astronomical number. Therefore, all predators will never lack a source of food. "

"Moreover, each different area is protected by a special Space Rule. Predators of other levels are unable to enter. The ocean is the first layer of the Evolution Space. All creatures that leave the surface of the ocean are refused entry by the Space Rule. The sky above the ocean is the second layer of the Evolution Space. Any creature that leaves the sky above the ocean will also be refused entry. This ensures that the source of life evolution will never dry up. "

"It seems that time in this world has an accelerated effect on the Evolution Rule. The Space Rule is to protect the continuation of this evolution. "Neptune finally analyzed the uniqueness of this world's Space-Time Rule.

"Accelerated Evolution Rule? Do you mean that the effect of time acceleration only works on the Evolution Rule and not on anything else? Is that possible? "Gu Ding was a little puzzled by Neptune's analysis.

"Under normal circumstances, it definitely won't work. It's like a rope. No matter what space you put it in, the total length of the rope will not change. However, since the Time Rule is messed up, you can think of it as a rope made of pure cotton. Under the messed up Time Rule, it will shrink like it has been soaked in water and then taken out to dry. Therefore, it is possible. "Neptune's analogy was quite common, but Gu Ding finally understood it.

"Can this kind of rule also work on me?" Gu Ding suddenly asked curiously. If that was the case, he could probably evolve to a rather terrifying level in a year's time.

"No, the creatures born in the ocean have an abnormal Evolution Rule in their bodies from the time they are still microbes. You are a foreign creature, and the Evolution Rule in your body is different from theirs. "Neptune's words dispelled Gu Ding's excitement.

Hearing Neptune's answer, Gu Ding's somewhat excited mood suddenly dimmed. "It's so unfair. Those microbes only need a few days to eat to become a Lower Rank Deity. Just thinking about it makes me feel so happy living in this world. I don't need to cultivate every day. I just need to keep eating. "

"You're too naive. This world is completely closed off. Even that Heavenly God can't escape. In my opinion, it can be seen as a pasture for that Heavenly God. If that Heavenly God wants to keep evolving, it must keep devouring existences whose strength is second only to itself. As for those who are not strong enough, it will slowly raise them until they grow up to be eaten. Then, it will devour them. That's why there is only one Heavenly God in this world, and not even one Greatest King. "

Although Neptune did not see that Heavenly God devouring other life forms, he did not see a Greatest King, so he made this cruel guess.

Although this guess was cruel, it made a lot of sense. If that Heavenly God did not devour existences weaker than itself, it would not be able to evolve. Not only that, it was possible that other fellows would evolve to Heavenly God level and replace its position at the top of the food chain. It was even possible that it would become food. Therefore, the only thing it could do was to devour those existences that were about to break through to Heavenly God level and kill those that might threaten its position, and continue to evolve.

It only took Gu Ding a moment to understand this principle.

"Actually, this place is not without its benefits for you," Neptune suddenly said with a smile. "All the life forms here are powerful flesh and blood life forms. It's a very good choice for you to improve your physical strength."

"That sounds like a good idea. There's still room for improvement in my physical strength and the divine powers of the Imperial Manifestation Body." Gu Ding had also made up his mind to improve his physical strength in this year's time. He wanted to cultivate the Emperor Body Manifestation to Level 3, the Emperor Body Realm.

"Then go all the way in the direction of two o 'clock. There's a city about three thousand kilometers away. When you get there, you can take a break and see the customs of this world. "Neptune quickly came up with a plan for Gu Ding.

"There are cities in this world? Were they built by the savages you showed me before? "Gu Ding was a little surprised.

"No, there are humans in this world too. In the video projection I showed you before, those savages are just human-like creatures. They are not real humans." Neptune knew that Gu Ding had misunderstood. "The humans here look similar to the humans in your previous dimension, but they are a little more burly and strong, similar to the physical cultivators of the Middle Ages. Moreover, most of the battles in this world are settled by the strength of one's physical strength. There are only very shallow martial arts skills. Of course, there are some people who have physical strengthening divine powers, but they can't compare to the Imperial Manifestation Body. "

"Another thing is that all the creatures in this world, due to this abnormal evolution, have a common weakness — the strength of their souls is very weak."

"An Extreme Deity only has the soul strength of a demigod. Half-step True God, 1-star to 3-star, has the soul strength of a lower deity. 4-star to 6-star is comparable to a middle deity. As for 7-star to 9-star, it's comparable to a higher deity. First-rank and second-rank True Gods have the soul strength of an Extreme Deity. "

"Your soul strength is that of a 1-star half-step True God. Without using combat effectiveness enhancement, you can crush a second-rank True God here. If you use combat effectiveness enhancement, your soul strength will reach the standard of a 9-star half-step True God, which is enough to kill an eighth-rank True God in this world. "

Neptune finally brought good news that delighted Gu Ding. The weakness of the souls of the creatures in this world was perfectly countered by Gu Ding. Although Gu Ding had not cultivated many soul-type techniques, his soul strength had always been no weaker than his physical body. Moreover, he had learned some simple Soul Attack methods from Neptune, which were more than enough to deal with the creatures in this world.

"Use the Soul Attack when it's necessary. Now is the time to train my body." Gu Ding unleashed his full combat effectiveness and rushed toward the herd of beasts not far away.
