Yoon didn't react to Krizen's soul splitting allegiance in the first place. At this moment, he was concentrating on sensing the changes in his body due to the fusion of the fairy soul and the body of the immovable fortified city.

In Yin Eun's original vision, if the Forerunner of Steel wanted to reach the fourth stage of consummation, he needed the goblins and the immovable fortified city to reach the fourth energy level and merge at the same time, and also have a specially made 'Void Machine God' to resonate with his soul, and completely achieve the quadruple perfection of 'body', 'soul', 'skill' and 'essentia', and become a flawless super life in a sense.

But in practice, this is a theoretical 'perfect progression'...... In fact, if you just want to have a strength equivalent to the fourth energy level of the traditional path of sublimation, you don't need to be perfect, and the Forerunner of Steel can almost make do with such strength.

Immovable City has long held the 'Aether Heart' of the fourth energy level, the 'Blazing Heart Marrow' of the fifth energy level, and the 'Dragon's Heart Core' of the fifth energy level.

The goblins hold part of the fragment of the fifth energy level, the core of the ladder of life, and the complete 'Gift of the Star God'.

And the specially made 'Shal Machine God', that is, 'Terra's Heart', has also been made by Yin Eun a long time ago.

To be honest, if it was just the pursuit of the blood of the fifth energy level, then Yin En would have already raised two or even three fifth level sublimation organs, and when he completed any fourth energy level bloodline true form, he would immediately start preparing to achieve the fifth energy level, which was fast enough to make everyone stunned.

This is the so-called 'deep foundation' and 'invincibility of the same level', when you don't need to be invincible at the same level, you can immediately convert to realm suppression, and Yin En's hard work in the early stage to find various resources and self-enhancement will finally bear fruit.

But because Yin Eun needed to create the inheritance of the arcane path of 'Pioneer of Steel', he couldn't be so casual, so he stuck himself in the third energy level that couldn't go up or down.

This does not mean that Yin En's strength is inferior, in fact, with the simple body of a third-level goblin, Yin En can already compete with the fourth-level Great Demon Deathknell, and at that time, his soul materialization is already not inferior to the fourth-level with the blessing of Terra's heart.

And if Yin En is willing to dismantle the body of the dark gold dragon, he can also cast the materials of the fourth energy level of Immovable Jiancheng at any time.

However, none of them are needed anymore. Because under the return of the Silver Sky Gate, Yin Eun's heart light body has grown by leaps and bounds, and it is adjusted with this as the core, plus the 'energy system' with the ether furnace as the core, the 'thinking center' with the Terra's Heart base station as the core, and the 'spiritual energy head' with the fairy soul as the core.

At this moment, Yin En has already touched the bottom line of the fourth stage of the Foremetal Pioneer, and has the most basic fourth stage combat power.

The power of this fourth stage bottom line alone is enough to compare to the original Yin Eun of the 90% fourth energy level peak created by Krizen!

Therefore, the original Yin En really underestimated the current Yin En who gathered so many path technologies to create the arcane path.

On a par? Oh, at that time, Yin En's strength was definitely able to far surpass the original Yin En! If you really want to give Yin Eun a complete Forerunner Fourth Stage Great Perfection strength, just see if he doesn't kill in seconds!

"The Forerunner of Steel can also be further optimized, the 'Ice Hell Floating Dust' that I accidentally obtained before, this nano-level sublimation material can once again strengthen my fourth stage of the Forerunner of Steel, and the power operation and flexibility of key areas, as well as the speed of self-repair can be qualitatively changed." Lowering his eyes, Yin En looked at his hand thoughtfully: "But in fact, even the third stage of the Forerunner of Steel has surpassed the original fourth level of sublimation in the evolution of the essence of life. ”

"By the time I reach the fourth stage, I am afraid that the limit life expectancy will exceed the two hundred years I said at the conference...... It's four or five hundred years closer to the real dragon! "This is the sublimation of the essence of life, and the fourth stage of the true forerunner of steel is no longer a simple fusion of two potions, Yin En pondered the next path: "If you want to reach the realm of Great Perfection, you also need the 'Attack Module', 'Body Composition' and 'Aether Perception Module'. "The attack module is actually not difficult, you only need to further strengthen Yin En's current electromagnetic force and gravitational manipulation ability, and the dark gold dragon can provide it perfectly, just to see when it is dismantled.

The body composition is also okay with the follow-up of Immovable Jiancheng, but Yin En plans to add some nano materials to form a nano body that is also extremely soft and controlled by electromagnetic force.

And the final aether perception module, in fact, is not difficult, Yin En's guidance star is a standard chrono-temporal aether organ, it is not surprising to use the fifth energy level, now what needs to be done is how to accommodate it into the system of the Forerunner of Steel.

Not to mention, the Gift of the Star God can also be regarded as a complete set of ether modules, Yin En can now have the bottom line of the fourth stage of the arcane path, and the overall increase in the gift of the Star God is very significant.

Although it took a long time to think, it was actually only a moment, and Yin En sorted out his current strength and thought about the subsequent path of advancement.

By the time he had completely completed the fourth stage of the Arcane Path and reached the pinnacle, with the power of the fifth energy level sublimation organ that Yin En now held, he was not even afraid of Terra's top powerhouse, and even had the confidence to blast it down!

"Now, can you tell me about your cooperation with the Emperor?" Raising his head, Yin En looked at the soul of Krizen, who had already come to his side: "What kind of big deal is he going to do, it is so mysterious, I can't find a clue in the entire empire." "[Actually, even I don't know the whole picture] Split Soul shook his head and said, "In addition to the Floating City technology and related network technology, I have reached a collaboration with Axel in psionic research - he is also interested in the 'Eternal Path', but he is not interested in traveling to other parallel planes by himself, but is interested in how to locate the 'self in other planes']

"Locating the self in another time and space?" Yin En frowned, obviously getting an answer, but he was a little incomprehensible: "He himself doesn't want to be an eternal person, why does he want to locate himself in parallel time and space?" "Could it be that Axel, like him, plans to chat with other alternate selves and acquire some technology?

Or open a chat group for the emperor of parallel time and space? Shaking his head and shaking off this doubt, Yin Eun continued to ask, "What about Isengard?" The reason for inviting me is simple, but why should I invite Isengard? "You don't know?

Instead, the soul split wondered: [This little guy has the blood of Yin Naijia II's inheritance in his body, which is related to the Beast of a Thousand Stars - my bloodline of Night Shadow is the 'soul' of the Beast of a Thousand Stars, and his refining light eclipse dragon is the 'body' of the Beast of a Thousand Stars!]

【Axel needs the Yin Naiga II Inheritance Key in this little guy's body, although I think he will definitely not find it, but I can also observe how the bloodline of a Thousand Stars Beast fused with the Sun God Bird will happen...... Looking at it now, although it is very strong, it is still not as good as your arcane path] [However, in your past reflections, I do know why Axel cares so much about this kid...... It turns out that he is the man-made Thousand Star Beast Suppressor, too, and only the light-speed thinking of the Sun God Bird can completely suppress every organization of the Thousand Star Beast's huge body] [Yin Naiga II, he did hold the key and suppressor that threatened all the forces of the entire Terra, it's a pity that he died too early, and fortunately he died early, otherwise, Terra would definitely be finished, and you wouldn't have the chance to grow up] Krizn is quite aware of the madness and extremes of the major forces in Terra, If the major forces knew that someone had both the detonation and containment abilities of the Thousand Star Beasts, and could cleanse the earth at any time and stop it, then they would not secretly attack the Dark Moon turmoil, but would directly form an alliance and push it to the gate of the imperial capital.

"Of course I do." Yin En frowned slightly, he felt that things could not be so simple, but Krizen had no reason to deceive him: "Strange thing, if you look at it this way, it seems that Axel is really just following the research of Yin Naga II to restore it - but how is this possible?" "[Yes, how is this possible] Split Soul also shook his head slightly: [Of course, I guess, he plans to borrow the power of the Thousand Star Beast to break through to the sixth energy level, just like one of my previous research topics...... With the thinking of the Sun God Bird, maybe it can really be done] [He asked Isengard to come over, probably planning to wait for me to study it carefully, and then come to me to ask for information.

For the sake of cooperation, I will indeed give it to him] At present, this is the case...... Axel was aware of Krizen's research on the Thousand Planets and the Eternal Path, so he simply sent Isengard who met the requirements, intending to directly harvest the relevant research results.

As for Isengard himself, there is a high probability that there will be no problems, at most cooperate with the experiment, and the capital of knowledge will also send it over - maybe what benefits can be obtained, win-win!

But Yin En knew that if Axel didn't pursue winning twice, he would definitely not become emperor.

It's just that it's useless to think about it now. Because the lockdown of the capital of learning is over. The demon cluster is still flying around the City of Knowledge, converging around the Gate of Silversky, but the Gate of Silversky has entered a period of dormancy after the end of its return to Yin Eun, and no matter how much the demon wants to sacrifice his soul and turn it into pure information to go to other parallel planes.

And the floating islands of the capital of various universities and knowledge are also guarded by the corresponding sublimators, with the eight spire masters, as well as the dispatch of the towers, they cooperate with the Terra Void Machine God forces that have gathered from all directions, and have suppressed the attack of the demon cluster.

As for the national missions...... Now they are calling the troops of their respective hometowns, and under the pretext of defeating the demons, they are sending their own elite mobile units to the capital of knowledge.

Taking advantage of the civil war between the two fifth-level people in the City of Knowledge, whoever arrives first in the City of Knowledge to protect this City of Knowledge will be able to obtain more righteousness and benefits!

From Yin En's standpoint, the gathering of envoys from various countries is definitely a big trouble for him, the pioneer of the arcane path.

As long as the fifth energy level doesn't make a move, the dragon king won't make a move, as long as they lead a large army and forcibly invite Yin En to their side, then Yin En ...... Yin Eun had no choice but to strike and crush their army.

[The troops of the Flying Flame Land and the troops of the Far Shore Island came quickly, and the forces of the Seven Cities Alliance and the Empire followed] Krizen's soul splitting said: [I see, they are already aware of your existence and the terrifying combat power of the Arcane Path...... They will definitely not let you go easily] At the same time, Yin En also heard the hints of Isengard and Mentor Frozen Fish.

"Yin En, there is a whole Flying Flame Land Aerospace Division group that has come to the periphery of the Heavenly Capital, it is led by the Celestial King, plus the previous Crown Prince of Celestial Thunder, there are two fourth-level powerhouses!"

"On the other side, the Spell Legion of the Far Shore Island is also approaching in the Void!" Isengard's tone was solemn, the body of the dark gold dragon also came to Yin En's side, and the frozen fish mentor also said solemnly: [I have asked the goblins to speed up, but we want to leave...... I'm afraid there's no way to go back to Dragon Island so simply] The battle between the Koryzon body and the guardian blocks the entire path to space, and if you want to go up from here, you have to deal with the aftermath of the battle between the two fifth-level first.

Even the current Yin En definitely didn't want to try this kind of thing, so he directly turned his head and looked at the legion of the Flying Flame Land: "A whole Aerospace Division? Two fourth energy levels? ”

"They don't think that's going to stop me, do they?" [It really can't] split the soul and said: [So it's not just them - look, their targets are all you] Sensing something, Yin En suddenly looked back, and he was stunned to find that unconsciously, the envoys of many forces in Terra, those fourth-level powerhouses, and even several spire masters in the capital of knowledge were vaguely centered on him, building a huge line of defense.

[-Mahdi!] At this moment, Yin En suddenly received a psychic communication from Romani, the Lord of the Molten Iron Spire, and the Lord of the Clear Moon Spire: [Everyone has reached a consensus, first arrest you who can cause the mutation of the Silver Sky Gate before thinking about the rest!

【You are not only the holder of the arcane path, but also the resonator of the Silver Heaven Gate, related to the two great paths, no one can resist such a temptation!

】

“…… Thanks a lot. Yin En paused, and then said, "What about you?" "[We? Romani's somewhat puzzled voice sounded, and then suddenly said: [Remind you that you are looking at the relationship between me and your junior brother is a partner, I actually want to arrest you for research - one yard to one yard, and I will do my best later] [Indeed] The Lord of the Clear Moon Spire also said softly: [I am reminding you for the sake of your junior brother saving Carlos, but I will not show mercy to my subordinates later] What the hell is Carlos, the eldest prince also has an old lover in the capital of knowledge?

So how does his princess feel? Oh, the Terra nobles are playing a lot, no one cares about that, that's fine.

“…… Dragon Island can't go back for the time being, and the direction of the Flying Flame Land, the Empire, and the Far Shore Island can't be ......" Yin En looked around at this moment, and he sensed that more than fifteen fourth-level powerhouses were surrounding him in a three-dimensional formation, and there were a large number of troops and air and space armor.

He didn't think he couldn't beat this group of people, but the longer he was dragged and the more people he was beaten, he had to show his full strength - at that point, if he accidentally revealed Yin Eun's unique technique, his waistcoat would be completely gone.

Mahdi can run, Yin Enke can't run, at least Yinfeng can't lead. So, a direction must be found.

"Let's go." Soon, Yin En determined the direction of the breakthrough: "Let's go northeast and go to the Holy Mountain!" ”

"Huaiguang Holy Mountain!"
