They won the Holy Grail War, but this turned out to be the Virtual Tree Universe.

Chapter 108 A World Where the Age of Gods Did Not Disappear
Dan Lei decided to go to another world to accumulate power, and after returning to overpower that foul-mouthed Fourth Mirror, he immediately said...
"Two systems, huh? You just wait here!"

After saying that, Danlei left his magic mark behind the mirror, and then drew a space-isolation array on the ground.

Given the Fourth Mirror's abilities, unless Black Tower helps, it's definitely impossible to leave this room using spatial abilities right now.

As for leaving by moving, this thing has no hands and no physical interference capabilities. If you damage the automatic door, it won't even be able to open it.

Dan Lei did this to prevent the Fourth Mirror from playing dirty tricks on him and stalling for time by playing hide-and-seek with him on the Black Tower Space Station.

Because this mirror is now clearly very dissatisfied with itself and is determined not to see the Black Tower.

After the insurance was completed, Danlei ignored the fourth mirror's protests against the confinement of the two systems and rushed back to his room.

To get back to his room, Danlei was certain that there were no surveillance cameras in his room.

As for whether the Black Tower might be watching him from across space using special means, that is indeed possible.

But the Holy Grail's passage is only instantaneous; Danlei only needs to conceal his figure for a few seconds.

Therefore, upon returning to his room, Dan Lei immediately activated the Cloud Chant Technique, enveloping the entire room in mist containing imaginary energy.

In this way, even if the Black Tower is monitoring, it will still take some time to switch monitoring methods.

Taking advantage of this air raid, Dan Lei initiated the Holy Grail's time travel.

The time and space have changed. This time, Danlei has been thrown into the streets and alleys of a modern city. Judging from the signs outside the alley, it should be in Japan.

As soon as Dan Lei landed, he felt an incredible concentration of ether in the air, almost like the Age of Gods described in the ancient books of the Type-Moon universe.

It seems that this world is extremely mysterious; the gods might still exist.

This is both good news and bad news for Danlei.

The good news is that with such a high concentration of ether, I can achieve twice the results with half the effort whether I'm casting spells or collecting magic power. It definitely won't take me more than ten years to complete the Holy Grail; it might even be full in a few months.

The bad news is that if the gods still exist, the fighting power of this world is hard to estimate.

Gods are a very peculiar thing. From a cosmic perspective, the so-called gods on Earth are just planetary gods, which are theoretically nothing special.

However, that's from the perspective of a normal technological universe.

If this world were solely governed by mysticism, gods could range from celestial beings to complete novices; anything is possible.

After all, if Dan Lei were to arrive in a world with a prehistoric setting, someone of Hongjun's level might be considered an underestimation of him, even if he were a Star God.

Moreover, there are cases even in the Star Iron Universe of a world or a wondrous object that can connect to the Tree of Imaginary Numbers, which can cultivate Commander-level powerhouses who are not destined travelers.

And don't forget, in the Star Iron Universe, from a cosmic perspective, the age of the Star Gods is actually not long. Even if we calculate each Amber Era as the maximum of 240 years, the 2157th Era, which started with the Star Train, is only 522,000 years.

Paleontological research on Earth involves studying an era that can range from several million to tens of millions of years.

Furthermore, it has been clearly stated in the game that although the Amber King was born very early, he was definitely not among the earliest.

Even if the timeline provided by the Interstellar Peace Corporation is inaccurate, the Amber King is unlikely to be more than one million years old.

Moreover, during the 0-180 Amber Period, the ancient beasts, once the rulers of the universe, were still active.

The Twilight Beast is a powerful creature capable of waging war against the Star Gods, and it can move freely between worlds isolated by imaginary energy using its physical body.

So, in the era before the birth of the Star Gods, how did humanity, or intelligent life, manage to fight against these beings with the resources of an entire world in order to maintain the continuation of civilization?
There are only two answers: either humanity has strong protectors, and the ordinary ancient beasts of the Twilight cannot wipe out humanity.

Alternatively, humans could submit to some of the ancient beasts they could communicate with and survive under their protection.

Now, due to the severe lack of information about the period before the birth of the Star Gods, it is likely that apart from the ancient Star Gods themselves, no one knows anything about humanity before the birth of the Star Gods.

However, in the Star Iron Universe, one thing is quite clear.

Even without specific examples, most major powers acknowledge that those who are not destined to follow the path of destiny, and who do not rely on technology, can theoretically produce powerful individuals comparable to or even stronger than Commanders.

Destiny and technology are not the only two paths to becoming stronger in the universe.

Those powerful human beings buried in history, before the birth of the Star God, may very well have reached this level.

Therefore, Danlei will not underestimate the so-called gods just because Earth's civilization has not yet reached the universe.

If these gods are similar to the guardians of human civilization before the birth of the Star Gods, reckless behavior might result in being slapped to death.

So, as usual, Danlei decided to first confirm what kind of world this was before considering his next move.

As soon as Dan Lei stepped out of the alley, he immediately noticed something was wrong. Why was there no one around? This strange magical fluctuation was similar to a spell used by a magician to dispel distractions.

Upon sensing the spell, Dan Lei roughly guessed that he was currently near some event in this world, so he immediately activated his senses.

Then, Danlei discovered that the person who unleashed the spell didn't seem to have any hidden intentions.

Because the magic of the park's barrier nearby is completely undisguised.

However, this magic is very weak for Dan Lei now, and the person who set it up is definitely no match for him.

Therefore, Dan Lei directly flew to the barrier on the Sun Wheel Flying Sword, wanting to see who set up the barrier and whether he could determine which world this was.

Whether it was confidence or arrogance, the person who set up the barrier didn't leave any traps outside, and Dan Lei flew to the top without any trouble.

Moreover, the barrier was not concealed, and you could see the entire interior just by looking down.

Then, Danlei immediately determined which world this was.

A fallen angel with two wings and black hair was sitting by a fountain in the park, with a boy who looked to be about high school age in front of him.

The boy was incredulously backing away, while the fallen angel watched him with a cat-and-mouse expression.

Given this scene, these characters, and the extraordinary concentration of ether in this world, it's almost certain that this is the world of the Breast Dragon Emperor, the world of the famous harem anime High School DxD.

The female fallen angel is Rena Rei, who goes by the alias Amano Yuuma, while the male high school student is Hyoudou Issei, the protagonist of this world and the current Red Dragon Emperor's gauntlet wielder.

Seeing this, Dan Lei mentally complained, "How did the Holy Grail choose this world? I just lost my virginity due to a reproductive experiment accident, and now I'm thrown into a harem anime, the kind that's so popular it's known for its fan service that it'll land me on the 'protection' blacklist."

However, besides beautiful girls and perks, there are also many dragons in this world, and Dan Lei is very interested in the technology of both divine artifacts and man-made divine artifacts.

In an instant, Dan Lei had already set a few small goals for himself in this world. To meet those Dragon Kings and Orpheus, and if possible, to meet the True Crimson Dragon God Emperor as well.

Then, acquire the technology for creating artificial artifacts, and if possible, also explore the technology for manufacturing them.

Dan Lei set two goals for himself. The first was to see if the dragons here could help his lineage of enlightenment, and whether there were any dragon-specific cultivation techniques or similar things.

After all, in my memory, the author of High School DxD did not describe the life and training of dragons in detail. Things that are not explained in the original work are usually filled in in reality.

As for the latter, the artificial artifact manufacturing technology can be combined with the Divine Machine Refinement technology. If he could obtain the artifact manufacturing technology of the Angel God, he would have a better chance of success on the Star Iron Road.

Therefore, when Rena released the power of light, forming a crimson light spear that pierced through Hyoudou Issei's abdomen, Dan Lei decisively made his move.

Dan Lei had no interest in watching Hyoudou Issei interact with various beauties and build a harem. Moreover, he quite disliked protagonists like him who wore their desires on their sleeves and engaged in all sorts of bizarre behavior.

Therefore, Dan Lei planned to end Hyoudou Issei's fate right here. Coincidentally, he also needed Dreig as a guide for this world.

After all, now that the world has been determined, Dan Lei has also roughly determined his own strength and position in this world.

In terms of destructive power alone, Dan Lei, with the power of command, is now capable of directly destroying human civilization on Earth, but he is not quite ready to explode a planet; he would need to activate the pyrolysis death ray several times to achieve this.

The combat power levels in this world, from lowest to highest, are:

Lower-ranking demon (two-winged angel)
Intermediate Demon (Four-Winged Angel)
High-ranking demons (six-winged angels, high-ranking fallen angels, high-ranking magicians, church S-class warriors)
Highest-ranking demon (eight-winged angel)
Special-class demon (Dragon King level, Ten-winged Angel, Fallen Angel executive)
Demon Lord level (Twelve-winged Angel)
Super Demon King
Transcendent (God-level, Chief God-level, Celestial Dragon-level, High God) PS: Starting from this level, one can violently destroy the world.
Lesser Dragon God level
Dragon God Level (True Crimson Dragon God Emperor, Complete Form Orpheus)

Super Dragon God Level
Far surpassing Dragon God level, Evil God level

Therefore, Dan Lei estimates that without going berserk, the destructive power at full strength is roughly between the Super Demon King level and the Transcendent level. The full-power berserk mode is unknown before meeting Orpheus.

Because of the so-called Dragon God level, Dan Lei suspected that it was possible that the level had already reached the standard of the Commander.

After all, being able to live in the dimensional rift already gives it a bit of the feel of a Twilight Beast.

In the Star Iron Universe, apart from organisms that have specialized and developed adaptations, none of the others who can survive in such a place are weak.

As for the last two levels, Dan Lei can ignore them. After all, he can't wait until the plot develops to that point. He will leave this world as soon as he achieves his goal. He doesn't care about those major events that are almost out of control.

So after Dan Lei broke through Rena Lei's barrier, he directly stomped on and shattered the blood-red light spear in her hand. Then, he used a healing technique to save Hyoudou Issei, who was seriously injured and on the verge of death.

Then, Dan Lei looked at Lei Na Lei and said...

"The fallen angel is really getting worse and worse, actually attacking a male high school student whose divine artifact hasn't even been awakened yet."

Dan Lei's appearance startled Rena Lei, because in this world, the aura of a dragon on Dan Lei was too obvious.

In this world, there are no weaklings among those associated with dragons, so Rena asked nervously.

"Human dragon descendant? Who are you? Why are you interfering in the affairs of us fallen angels?"

However, Dan Lei completely ignored Rena Lei's words and instead turned to Hyoudou Issei and said...

"Young man, sign this contract and agree to hand over your divine artifact to me, and I will save your life today."

After saying that, Dan Lei handed Hyoudou Issei a self-compulsory certificate.

Hyoudou Issei almost died just now. Having always been an ordinary person, he had never experienced anything like this before, and he was now terrified.

At this moment, Dan Lei said he could save his life. Considering that Dan Lei had just treated his injuries, he immediately took the self-compulsion certificate and said...

"I'll sign, I'll sign, brother, please save me, please save me, I don't want to die."

However, just as Issei Hyoudou was about to sign, a sudden intuition told him that once he signed, he would lose many important things.

Seeing this, Dan Lei immediately activated the Twelve Labors Formation, instantly pulling Hyodo Issei's fear and impulsiveness to the surface.

Hyoudou Issei instantly recalled the feeling of almost dying just now. The fear of death instantly suppressed his intuition, and he signed the document without hesitation.

Seeing Hyoudou Issei sign, Dan Lei smiled happily and looked at Reina Lei.

Rena felt a chill run down her spine instinctively and roared again.
"Killing me won't let the fallen angels get away with it, I'll build..."

Before Rena Lei could finish speaking, Dan Lei placed his palm on her head and used magic to pulverize her brain into mush.

Then, using the Soul Binding Technique, Dan Lei extracted Rena Lei's soul from her body.

Forcibly stripping a divine artifact would result in the host's death. Dan Lei had promised to save Hiei Teng Issei's life today, so naturally he couldn't let him die.

Moreover, artifacts need to be bound to the soul, and Dan Lei didn't want his soul to be tainted by too many foreign objects.

Therefore, Dan Lei didn't actually intend to learn from the other transmigrators who transmigrated to the world of High School DxD and directly strip the Red Dragon Emperor's gauntlets from Hyoudou Issei.

What Danlei wanted to do was to use his understanding of souls and the power of his memories to directly replace the soul of the Crimson Dragon Emperor Draig with the soul of Renare.

At that time, the Crimson Dragon Emperor's soul will be captured and turned into a spirit by himself using the Spirit Binding Technique. In any case, his abilities will be retained once he becomes a spirit.

Moreover, the Crimson Dragon Emperor's current state is very similar to that of an "immortal" in the game "Under One Person". As long as Dan Lei does not deliberately suppress him, he will not lose his intelligence.

As for what the soul within the artifact gauntlet, which transformed from the Crimson Dragon Emperor into a fallen angel, will ultimately become, that is a case that Dan Lei needs to observe.

Of course, if Danlei's plan fails and he is unable to extract Draig's soul from the artifact, it won't matter.

At that point, we can risk paralyzing Hyoudou Issei's left arm by tearing his soul apart from the artifact.

As long as he doesn't die, Danlei isn't considered to have breached the contract. At worst, they can make him a mechanical arm as compensation.

　Before the birth of the Star God, there were powerful beings among humans who could fight against the Twilight Ancient Beasts, although there is no concrete evidence in the text.

　　However, it can be basically assumed that they definitely exist, otherwise it would be difficult for human civilizations in many worlds to survive on a large scale, or even for concepts to be elevated.

　　After all, only one of the ancient beasts, the Gluttonous One, was elevated to become a Star God, and the first thing the Star God did upon its birth was to destroy the ancient beasts.

　　Therefore, it can be basically concluded that these philosophical concepts are not from the ancient beast civilization.
　　Moreover, at that time, the various realms were not connected, so these powerful individuals could only have been cultivated in a single world.

　　This is not a secondary creation; it is based on research of fragments of information from the Twilight Beast.

　　Of course, it could be the work of a fictional historian, but the existing materials allow us to deduce this answer.
