After leaving Ye Tianhua's residence, Du Fei's questions not only did not decrease, but became more and more.

Life troubles and literacy began, probably that's what it means, right? If you don't know anything, you can ignore it and don't guess.

Du Fei raised his right hand and shook it slightly, releasing a cloud of light blue source power.

Looking at this mass of source power, it suddenly occurred to me that maybe the source force was a kind of dark energy.

If the source force is some kind of dark energy, before the end of the world, human beings will not be able to discover the origin of the source force at all.

Until the end of the world, Pandora creatures appeared, bringing disasters and opening the door to touch dark energy.

Du Fei returned home, first played a game of controlling iron sand with Illya for a while, and teased Yaya, this little demon king was angry when he teased, and he was going to be crazy if he teased again, showing his teeth and dancing his claws like a little tiger.

Then he went back to his room and took out the Void Armor fragments and the mysterious broken blade. Holding two things, they knocked on each other, making a crunch sound of metal clashing.

However, it is clear that two things are not exactly metal. Perhaps, the essence of these two objects is a mixture of metal and some kind of dark matter.

At the height of human scientific and technological civilization, the spear and shield have been completely unbalanced. In the era of cold weapons, shields can block arrows, but in the era of hot weapons, nothing can withstand the explosion of nuclear bombs, except for the two substances in the hand that do not belong to human civilization.

If humans can master the energy force field and defend the barrier, then the relationship between the spear and the shield may return to a state of equilibrium.

It was once believed that nuclear energy was a forbidden fruit for mankind to steal, and that civilization had gone down a deformed path.

Du Fei still couldn't use the source ability to control the two fragments in his hand, although he could feel that there was some kind of metal contained in them, but increasing the magnetic field force to the strongest could not affect the fragments.

Unable to peek into the secrets of the fragments, Du Fei could only turn to the study of the vanishing shadow demon Zeratul.

I found a mirror, opened the kaleidoscope writing wheel eye, and carefully examined the state of the pupils, and found nothing abnormal, but in the face of the shadow demon Zeratu, the moon reading was inexplicably invalid.

If you want to figure out the situation, the best way is to try it again. So he slowly gathered pupil power in his left eye, and in front of himself in the mirror, he released the pupil technique moon reading.

As soon as the horizon changed, Du Fei entered his own spiritual world, which was still the vast and boundless land, the blue night sky, and a blood-colored full moon.

However, in mid-air, there was an inexplicable cloud of black mist-like energy.

Seeing this, Du Fei's heart moved, and he had already guessed a possibility, this black mist energy was the shadow demon Zeratu.

As he guessed, he casually controlled himself to float in front of the black mist, and felt an aura similar to that of the Shadow Demon Zeratul when he was fighting.

As if stimulated, the black mist suddenly contracted, and soon condensed into a humanoid black shadow wearing a black cloak.

Seeing this, there was no need to doubt that the disappeared Shadow Demon Zeratu was actually sucked into the spiritual space by himself.

It's just that the world of monthly reading isn't an illusory spiritual space? How can you hold a cloud of real energy? How can it be said that Shadow Fiend is also a mass of energy creatures with thinking and creativity, how can it exist in the mental space for a long time?

Although Du Fei couldn't figure out these questions for the time being, one thing was clear, he could control everything in the illusory space. Perhaps, this is the reason why the Shadow Demon in his previous life did not have a battle with Wang Shengliudao.

Before Du Fei could speak, the Shadow Demon Zeratu spoke first: "I didn't expect that you really have the civilization crystallization of the Sarnaga people in your body, I should have thought of it a long time ago, otherwise I wouldn't be trapped here." ”

"Sarnagar?" Du Fei asked suspiciously, this term had come out of Zeratul's mouth for the second time, and the last time was on the island of Eyre.

"A mysterious race, a race that has been creating monsters. Perhaps, the intelligent creatures of this planet, the humans you call them, are the products of Sarnagar. Shadow Demon Zeratu said with a wry smile, perhaps assimilated by human civilization, his words, tone, and expression were vivid, like a human ghost.

Du Fei suddenly found that he had caught an alien creature, and it was in his own mental space, so if he wanted to know anything, he could ask from his mouth.

"What does the Sarnagar race, in your language, mean?" Du Fei asked, because the communication methods are completely incompatible, so some of the terms are human beings, and they may not be the same as the meaning of what Zeratu said.

"Once an ancient faith, a mysterious observer. Now, it should be called a fallen civilization. Zeratu replied very happily, this information is simply some common sense content for him, and there is no need to hide it, but in Du Fei's opinion, it is a secret outside the world.

"Tell me, then, what kind of energy is your body made of?" Du Fei asked again, he had been puzzled by these questions for the past two days.

"Hmph......" Zeratul sneered, and instead of answering, he sneered, "Lower creatures, want to explore the mysteries of energy? It's better to give up, such a short life is not enough to support this pursuit. ”

"Say it or not, but I can't help you." Du Fei also sneered, raised his hand and waved, and with a burst of space distortion, Zeratu was scattered into energy fragments.

A few seconds later, the shadow demon Zeratu condensed from the scattered black mist into a prototype, and still sneered and said: "You can't hurt me, you can't control this spiritual space at all, and the product of this advanced civilization is a waste in your hands." ”

Du Fei frowned, and found that Zeratu did not feel pain, and then raised his hand again, and released his usual spiritual punishment towards Zeratu.

In the past, these spiritual punishments were able to cause great suffering to both humans and evolutions, but Zeratul was only scattered into a black mist every time, and soon returned to his original form.

After a few times, Zeratu sneered: "Don't waste your efforts, you don't understand this spiritual space at all, just use it as an appearance, you can never hurt me, it's better to give up." ”

Du Fei thought about it for a long time, and always thought that this illusory spiritual space was created by Yueyu, but after so many things, he gradually found that the things exchanged by the exchange system were not the prototypes of the items, but just some appearances.

The essence of the exchanged items is still the energy arranged according to a certain law, and the so-called exchange is just the appearance of the exchanged items. For example, if an exchange potion is opened for a certain period of time, the potion will become invalid. Regarding this point, Du Fei has long guessed that there should be some kind of energy in the potion, which directly transforms the human body, and it doesn't matter whether it is a medicine or not.

Du Fei thought about these things clearly, and found that he really couldn't do anything with the Shadow Demon Zeratu for the time being, but he was not discouraged, and he couldn't master this spiritual space now, which didn't mean that he couldn't in the future.

Only Du Fei knew in his heart that after every evolution, his control over the spiritual space would improve to a certain extent, and he could even see the inner world of some people in the spiritual space.

In that case, one day I will be able to dig out what I want to know from the mouth of Shadow Fiend.

"I don't care, I have time to deal with you. On the contrary, you can't leave this spiritual world at all, right? Du Fei was not hit by Zeratu's sarcasm, but ironically went back, the initiative was still in his own hands, and there was nothing to worry about.

"The day you die, I'll be free." Zeratul said with certainty.

"That's not necessarily, since you can exist as an energy body, maybe I can too, you just wait slowly. One hundred years, two hundred years, maybe I will pass on this spiritual space and let you be imprisoned here forever. Du Fei said with a smile.

"The intelligent creatures of this planet are doomed to perdition, and you are no exception." Zeratul said confidently.

"Then we'll see. However, I can see that you are not all the way to those alien monsters, and if you are willing to help me, maybe I will let you out. Du Fei said temptingly.

Zeratul smiled weirdly and said, "Do you really think you're trapping me?" ”

Du Fei's heart froze, and he was almost frightened by Zeratu's words, but after thinking about it carefully, if this guy could escape, he would definitely not stay here, and there would be nothing to worry about.

"Aren't you trapped? Then you get out, I can play with you here as I like. Du Fei said as he waved his hand to tear the shadow demon Zeratu into various shapes.

Until the shadow demon Zeratu became angry, he turned into countless black energy chains and swept in.

Du Fei just raised his hand slightly, and all the black energy chains were isolated from his body without the slightest pressure.

It was also the first time that the shadow demon Zeratu was teased by the low-level creature in his eyes, and he was extremely angry, but in this mental space, he couldn't do anything but let the other party torture him. After his body was torn into a scattered mist, he no longer gathered, but let the black mist float in the air.

Du Fei did not waste the time of reading this month, but seized the time to practice the control of the magnetic field and exercise the performance of the body.

"Boring creatures, it's a waste of life." The Shadow Demon Zeratu floated around Du Fei's spirit body, talking from time to time.

"At least I still have something to waste and a goal to chase. What about you? What are you after? Waiting to die? Or are you waiting to get out of here? Compared to me, you are the real pitiful, and you can't even act autonomously. Du Fei also sneered.

"Your life is so short, it's nothing to me." Zeratu said this, but Du Fei could feel that he was comforting himself.

"Really? So how many years have you lived? Du Fei asked casually.

"In your unit of measurement, that's 1,237 years." Zeratul said with some pride.

"I see, you hide in a blue bullet casing, and you sleep for 600 years, and it seems that your life is quite sad. Something terrible is probably hiding, right? Du Fei said.

Zeratul was silent and did not speak for a long time. Du Fei became more and more sure that he had guessed the reason why Zeratu came to Earth.
