Life force seemed mysterious and impossible to quantify, but in fact, it could be seen from certain signs. For example, when you see a tree with withering leaves, or a skinny old man that stoops low when he walks and seems so frail that the wind might blow him away, you would feel that they have a low life force, like their life force could go out at any moment.

Conversely, when you see a strong tiger with healthy muscles, or a young muscular man with healthy tan skin, you would naturally feel like they have a strong life force.

While Sheyan was still standing there stupefied, it suddenly started raining. The rain was so heavy that his vision was soon filled with a vast expanse of white, and he could even hear the roars of thunder. Sheyan immediately looked around to seek cover from the rain, but he then saw something which made him stop. When the sea water came into contact with the rain and was struck by lightning, an intriguing chemical reaction occurred.

Organic matter was born from the chemical reaction. Amino acids and nucleotides were the two most common and important biological molecules in animals and plants. They were the bricks and stones that constructed the buildings of life. They then became bacteria, then unicellular organisms...

Sheyan witnessed the evolution of life which usually spanned across hundreds of millions of years happening in front of his eyes in mere minutes. He could only watch on with gaping jaws. Just when he thought he would see them evolve into human beings, from the depth of the sea came countless s.h.i.+ning lights!!

Never would Sheyan have thought that the final form of their evolution were mayflies!! The mayflies, most famously known for having the lifespan of no more than a day! However, the life force in these mayflies had been concentrated to an astonis.h.i.+ng level! The life force inside a single mayfly the size of a palm was stronger than that of ten blue whales combined!

It must be noted that a blue whale has a lifespan of more than 60 years, some even reaching a hundred years. Meanwhile, these mayflies that were only as big as a palm had ten times the life force of a blue whale, but would completely consume the entirety of their life force in a single day. How dazzling would their lives be!!

"This is the biggest and most valuable secret of Noah Realm E!" A slightly excited voice suddenly rang in Sheyan's ears. Then, a ray of light shot out of Sheyan's Nightmare Imprint and soon formed a figure made of light.

Although the figure was faint, he could tell that it was vaguely feminine, and he felt an unspeakable feeling majesty and sanct.i.ty from it, and even felt the urge to wors.h.i.+p it. She turned around and smiled at the astonished Sheyan.

"Don't be surprised. I'm your mother Realm, Noah Realm C. In order to communicate with the contestants more conveniently, I will sometimes appear in this form. You can also call me Eve."

Sheyan suddenly understood. No wonder he would be feeling this way. Eve, as the bestower of his strength, would naturally possess this kind of power. By now, the mayflies had already rushed to the islands. They devoured the trees and leaves, grew, and mated with each other.

Mating is a process of life. During the process of breeding offspring, the life force of both the mother and the offspring will become extremely strong. In the real world, there are many cases of pregnant women who suffer from terminal diseases miraculously recovering by themselves during pregnancy and childbirth. The concentration of life force in the mayflies in Noah Realm E at this moment had rose to a shocking level due to the process of mating and reproduction!!

"So that's how it's purified," Eve remarked with a smile.

"Forgive my bluntness, but can you say that it in a more understandable way?" Sheyan could not help asking in confusion.

Eve gave Sheyan a deep stare and said, "Based on the achievements you've gained so far, you are indeed qualified to know these secrets. We Noah Realms aren't created by humans; we're products left by the Creator from the last Age. Although all Noah Realms have the same functions, our core methods of combat and survival are different."

"It's a bit like the different means of transport that you humans use in your everyday life. They all share the same function of making travel more convenient, but they are powered by different kinds of core energy. The core energy supply mode of a bicycle is human power, the core energy supply mode of an electric vehicle is electrical energy, a car is powered by fuel, a sailboat is powered by wind, a nuclear submarine is powered by nuclear energy, and a steamboat is powered by steam. It is the same for Noah Realms. Every Noah Realm has different secrets at its core."

Upon hearing that, Sheyan suddenly came to a realisation. He took a deep breath and asked, "You mean, the core secret of Noah Realm E lies in this sub-world in front of us?"

"Yes," answered Noah Realm C firmly. "That's absolutely right. This whole world seems to have been compressed to the limit. The only function of the living creatures in this world is to provide a constant stream of terrifying life force to Noah Realm E to be its core energy! This entire world in front of you is the core engine of Noah Realm E, the heart of Noah Realm E!"

"The evolutionary speed of these mayflies have been hastened billions of times. They contained strong essences of life which are further purified when they mate! See, the mayflies don't lay eggs after they mate, but wither and explode. Those white spots of light floating upwards are the purified essences of life. They will be supplied to the entire body of Noah Realm E to support its activities."

"How can life be converted into energy?" Sheyan found it hard to understand.

Eve's reply sent him into a daze. "Think about your 'Extinction' ability and the Awakening Skill of your teammate, Reef. They're powerful attacking skills that can only be performed by consuming a certain amount of life force!"

Sheyan had no reply to that. He stared at the amazing sight, which looked somewhat like snowflakes flying all over the sky, in a trance. Never would he have thought that the Noah Realms had advanced to the point of using an entire world as an "engine"! Only after a while did he snap back to reality.

"What can I do for you, then?" he asked with some difficulty.

"You can see that the extracted essences of life are floating into the air. There must be a hidden energy absorption device up there. I'm currently in an illusionary state and have no combat power, but I can still a.n.a.lyse and calculate. You just need to go to where the energy absorption device is and stay there for a while," said Eve while staring into the sky.
