The strength of the Dark Gold Dragon is extremely terrifying, even the simplest breath can pierce through the clouds, and irregular pillars of light like splashes of ink sweep across the sky, causing a riot in the firmament and atmospheric circulation of the entire experimental space.

All the clouds disappeared in an instant, and the terrifying super hurricane appeared on land, and when the light golden light disappeared, the original atmosphere became an atmospheric ionization cloud that stretched for tens of kilometers long, and it emitted a blue-green aurora like a brilliance, stretching to the end of the horizon.

In addition, the Dark Gold Dragon's every move is also extremely terrifying and destructive.

When 'Goran' first teamed up with Mahdi and the others to attempt to destroy the Dark Gold Dragon's brain, she erupted in a terrifying dragon roar.

At that moment, the incredible shock wave ignited, evaporated, and shattered all the dust and macromolecular structures in the air, and a mountain that had been in front of her was blown away from all the trees in an instant, and the bare mountain began to burn and crack.

Soon, the mountain shattered and collapsed in one explosion after another, and was finally blown away by the terrible winds.

An entire mountain was shattered by the roar of the real dragon, and the explosion of the ultra-hot air swept the smoke and crushed rock into the sky, and the visible annular shockwave blew Goran and the others thousands of meters away, leaving only Mahdi barely in place.

These are the power of the fourth energy level - just a roar, a breath, can destroy all the troops and cities in an area, destroy the mountain peaks, replace the celestial phenomena, if it is the army of the nations, as long as there is no super unit such as the construction knight inside, the real dragon only needs to pass by to solve it.

The true dragon's eyes are brighter than the sun, and she can pull out a series of sonic booms when she flies in the air, and with a casual claw, she can make everyone cry and cry (calling the power of the elder's heart light body) to resist, and if it is a large-scale serious attack, even Mahdi will have to run away for a while.

If it weren't for 'Yin Eun' who played his role as a prophet at this time and was able to predict the scope of destruction of the Dark Gold Dragon, I'm afraid that someone would really die in the Xenomorph Research Institute this time.

Fortunately, this is a subspace labyrinth used by pre-era civilizations to experiment with biological weapons, and the degree of solidity is unimaginable, otherwise, I am afraid that the maze will be broken halfway through the toss.

The reason why everyone did not have a nervous breakdown under the attack of such a terrible enemy was only because of one thing.

That is, everyone found out that something was wrong with the dark gold dragon.

As Mahdi said, the dark gold dragon, despite its extreme strength, does not seem to be skilled in manipulating its body.

When attacking, the dragon's body loses all defenses; And when the dragon's defenses are gaining momentum, she can't launch any attacks.

This extremely unfamiliar performance of her body made it impossible for her to exert the strength of the normal fourth energy level at all, and it also gave Mahdi to entangle the real dragon who wanted to defend and gain momentum, giving the others time to prepare for the attack.

Mahdi's strength comes from the 'Pioneer of Steel'.

Just less than sixty percent of the forerunner of steel can give him access to the unprecedented 'strongest third energy level in history' realm, and if he can perfect it, he will surpass the constraints of the Terra energy level and become another existence comparable to the fourth energy level.

This perfection was supposed to be the third level of the 'Fairy Bloodline' and the two third-level Extreme Domains, but now, it has become a higher-level 'Body of Light'.

If it weren't for the 'Aether Transfer' of the Body of Light, the black-haired knight would not have been able to catch the terrifying power of the dark gold dragon eruption, although he could dodge the dragon's roar and breath, but usually the dragon waved its claws and flicked its tail, and the dragon chariot roared Xiaoxiao, he had to take it hard, not with a gun shield or a gun, but with a long sword.

The strength of the other young heroes comes from the 'hole cards' they have.

Aina is a piece of his father Carlos's mental light body, which allows him to temporarily exert the fourth energy level of 'rapid actinization' and 'Heavenly Sun' and other sublimation skills, both offensive and defensive, he is also the only one who can freely dodge and escape under the attack of the dark gold dragon, except for the dragon's gravitational wave breath, he can definitely run away if he wants to, this is the confidence given to him by the blood of the sun god bird.

Garr is a wind hammer given to him by his uncle, this invisible sledgehammer is part of the ether true body of the peak powerhouse of the fourth energy level, which can activate Gar's bloodline to improve his strength, and can also protect Gar, if he bursts out with full strength, it is equivalent to the full force of the strong man of Gontasimor - but Gar is not used to using a hammer, so it is converted into a long knife, which is why Gar was unable to break the Mahdi defense before, but then he was able to break the defense and cut out the bone wound.

The Summoner's brooch was given by his teacher, Duo Tieyu, and sealed with a portion of the spirit of the bell, and with her help, the Summoner can cross the barrier of the third level, summon the monsters and gods in the depths of his soul, suppress them, and make them his own heartlight, and then go into battle...... And the power of the bell can also strengthen the power of this mental light body, so that the summoner who can use psionic energy to control strong enemies can better suppress and extract the enemy's power.

Elg naturally doesn't need to say much, the combination of man and the beast of a thousand stars is a mystery within a mystery, and if it weren't for Mahdi, his true strength would probably be better than Aina and Garr...... In addition, the master of transformation, Sath Qingyue, also prepared a 'spell crystal' for his disciple, which was the full force of the master of the spire of the clear moon, and this scholar had been hesitant to use this power against Mahdi, but now it seems that fortunately it was not used on Mahdi.

Silver Salt Iron Cauldron, the silver elf silently answered Mahdi's call and engaged the Dark Gold Dragon. She actually doesn't have any special hole cards, mainly because the silver goblin is really strong - not to mention that the silver salt is a big goblin who has been reincarnated fifteen times, of which she has become a fourth energy level seven times, her combat experience is so rich that she can predict all the actions of the dark gold dragon, plus the goblin is originally a life in the virtual realm, and it is really like a fish in water in this environment, if it is not for the fact that this body is not strong enough, I really doubt that the dark gold dragon will be brushed by her alone.

Anfa's hole card is very simple - she only needs to inject this prosthetic body with a high concentration of true dragon blood and catalyze it to a dragon state close to the main body, and she can easily reach the third-level strength, plus the third-level dragon soul and superb dragon killing swordsmanship, the combat power is indeed not weak, and there is no need to show more.

As for 'Yoon'...... He is a prophet, and he is responsible for using the prophet as an excuse to manipulate this group of young heroes to cooperate with Mahdi, that is, Yin Eun's body.

This group of eldest young masters and eldest ladies has really never been commanded, and no one has completely scattered the sand.

Not to mention the last 'Goran'...... The other people's hole cards are all fourth-level psychic bodies, fourth-level all-out blows, or fourth-level reincarnation experience or something, but she came with the fifth-level soul split.

If it weren't for Yafoda's ban on the realm, the split soul in this elven girl's body would call on the power of the body, and with a single finger, he could beat everyone including the dark gold dragon to their knees.

To tell the truth, that is, Yin En's body is bigger than this group of people, otherwise, it is just an ordinary third-level peak, and it will be easily torn apart by this group of little monsters, and it is impossible for the ordinary fourth-level to kill them.

With a group of young handsome men who are open, the black-haired knight and the dark gold dragon are around.

He could completely see that the Dark Gold Dragon was essentially an 'echo', and she was just injecting herself into the body of the Dark Gold Dragon, that is, the young Steel Dragon, and controlling this body to fight...... That's why there will be situations where the control is not skillful, or even unable to fully control.

In this way, even this body may have been catalyzed for a short time...... Therefore, a large number of rare dragon blood and high-level bloodlines are needed for further optimization.

And Yin En's purpose is not to defeat this extremely powerful fourth-level dragon body, but to try to find the carrier of the 'echo' in the dragon body, break through the vital point, and kill with one blow.

It's not that hard. With the Foresight and the Silver Chip, he quickly found the place where the Echo was...... Not in the brain, not in the spinal cord, but under the heart, in the 'stomach pouch' protected by the keel!

Who would have thought if it wasn't for Foresight? In an instant, Yin En realized that the echo was not just data, she had a material entity as a carrier, she placed herself in a stomach pouch with plenty of space, and controlled the whole body of the dragon body through this upper and lower centered position!

- We must find an opportunity to destroy the 'echo body' in the stomach pouch...... At the very least, cut off its connection with the dragon's body!

This is Yoon's true purpose.

It's just that...... Even if the true nature and weakness of the Dark Gold True Dragon are discovered, the difficulty is still very high.

In particular, everyone was shocked to find that the learning speed of the Dark Gold Dragon was very terrifying.

During the battle, the Dark Gold Dragon's mastery of the body became more and more familiar, and the interval between the inability to defend against attacks became shorter and shorter.

She's constantly getting information on sublimation battles to improve herself!

"Mahdi, I'm afraid this dragon has never fought in the past, so it won't fight at all......"

After dodging another breath from the Dark Gold Dragon, Gar, who broke out in a cold sweat, yelled at the black-haired knight, "But now that she uses us as a training object, she has quickly learned a series of essentia manipulation techniques...... I speculate that in another ten minutes, the interval between her attack and defense will only be one or two seconds! None of us will survive but you and Ainagolan! ”

"Why?" The black-haired knight did not deny Gar's speculation at all, and he even coldly burst out more precise numbers: "After an hour, this guy will be able to learn the real fourth-level combat method through data iteration...... By then, none of us will survive. ”

"Then you should use your invincible Immovable Fortified City to think of a way!" The werewolf boy was furious: "I beat us so smoothly before, why did we get stuck when we slaughtered a dragon?" ”

"I'm thinking! Hold your horses! I'm in a better hurry than you! The knight's eyes lit up with a silver glow, and he gritted his teeth and said, "I have a ...... for the time being."

[No, you can't help it]

At this moment, the voice of the dark gold dragon forcefully inserted into the communication between the two: [Because I have learned the subtleties of the way of sublimation...... So, the mobilization of the essentia of the physical body requires the 'will', and the mobilization of the spiritual energy of the spirit requires the impulse or the emotion......]

[Finally, mix the two with 'faith'......]

"Oops! High concentration ether reaction! ”

At this moment, Elg on the other side exclaimed: "The enemy has begun to take the initiative to refine the primordial ether!" ”

As Elg put it.

At this moment, the attack was stopped, and the dark gold dragon, which had taken a 'defensive accumulation' posture, slowly took a deep breath.

Pure white smoke and red-gold light continued to rise from its burly and majestic body, and the pair of huge golden crystal wings behind it were even more rippling, which was a vision of a huge power overflowing.

The entire dark gold dragon turned into a small sun at this moment, emitting a gravity-disturbing light, and the surging water vapor around her made the dragon like a mountain floating in the air, surrounded by clouds and mist, and a sunrise appeared at the top of the mountain, that is, the head of the dragon.

Everyone present changed color, this was the first time that the dark gold dragon began to use 'technique' - all the previous breath, dragon roar, claw strike, and various physical attacks of the dragon's body were essentially children picking up the king's eight punches, and at most they went one step further, learning to clench their fists and smash them out.

But now, she began to adjust her body, breathe, stand up, turn her waist to attract the strength of her whole body, and the spine dragon bent, about to give everyone present a deliberate punch!

[Yin Eun, I've decided]

At this moment, the black-haired knight's mind heard Anfa's voice of determination: [I choose to be a dragon - I can accept the power of 'father' and transform myself into a true dragon...... By then, I will have enough strength to stand up to this true dragon! 】

[If this is really your heartfelt choice, I will definitely welcome it] and Yin En responded very quickly: [But I tell you, Anfa, if you deceive yourself even the slightest, you will not be able to succeed - in my prophetic vision here, you are still bright red, and the prophecy tells me that you are not ready, and you choose to be a dragon or lose your humanity or die]

[But it's also the last option.] If we really can't defeat this monster, I won't stop you from making a choice. 】

[Just now, I have a way]

"Everybody come behind me!"

Suddenly he opened his mouth and roared, and the black-haired knight shouted in awe of the slightly mocking smile of the dark gold dragon: "We can't block this monster's next attack, it's a full-map attack that covers the entire testing ground - only I can stop it, even if it comes at the cost of being hit hard!" ”

"Believe in Mahdi!" At this moment, 'Yin Eun' also spoke, and the white-haired prophet's eyes lit up with a watery halo, and he said solemnly: "I have found a way to defeat it, we need to entangle this monster in the time it takes for Mahdi to recover...... She hasn't learned to control the Aether yet, and she's bound to be exhausted when she attacks with all her might, so we'll have to use all of our cards to weaken her and unleash the last of our elders' protection! ”

"Keep attacking and suppressing her until Mahdi recovers!"

"Prophet, there is still the city of immobility, I don't know what the relationship between the two of you is, but you'd better not lie to anyone!" At this moment, there was no other choice, there was no time to escape, there was no time to dig a hole, not to mention that digging a hole might not be able to dodge, and the young powerhouses led by Gar and Aina could only come behind Mahdi as fast as possible.

They saw the knight's massive insect nest crystallized dragon heart light body appear out of thin air, and came to him, his wings and dragon claws folded, turning into a shield in front of him.

[Hmph...... It's useless]

Even if she saw through the strategy, the dark gold dragon didn't think about changing it, or rather, she didn't actually have the ability to change her moves on the spot.

The last echo just sneered: [I still want to thank you for teaching me the skills of fighting]

【Now, come and taste your own masterpiece】

The Dark Gold Dragon had finished charging, and a huge amount of energy gathered and shone in the hedron on her chest, blooming like a second sun.

And in the next moment, countless silky threads of red-golden light bloomed from it, but this was only the aftermath before the energy burst, the visible gravitational changes had already caused many rock formations in the test site to float into the air, and the air around the crystal nucleus on the dragon's chest had been completely ionized, blooming with a dazzling lightning and thunder—

And the black-haired knight was silent at the moment, mobilizing all his defenses.

Heartlight Body, Heartlight Shield, Essentia Shield, Essentia Layer of Dragon Scale Armor, Sand Armor, Blood River Armament, Magnetic Field Shield, Dragon Scale Armor Body, Flesh and Blood...... In just a split second, he stacked nine layers of shield defense on himself.

But that's not all - because there are others who put shields on the knights!

Ainar blessed the 'Sun Flame Shield' to reduce the damage of light and heat, Gar created a layer of ultra-high-pressure vapor layer to divert impact, and Elg and the Summoner created a layer of 'Psionic Rigid Body Shield' and 'Psionic Energy Absorber Shield' respectively, one can offset and reduce damage, and the other can weaken the power of enemy attacks.

An Fa blessed Yin En with 'essentia activation', and threw his psionic ornament over, which was a necklace with the logo of the Lamp Family, which contained a third-level 'Ning Mo Xiyan', which could curb most of the psionic energy and essentia reactions, and the silver goblin sat directly on the knight's shoulder, raised his shield, and raised his shield to fight against him.

As for 'Yoon'...... On the surface, it was a solid ice shield for the black-haired knight, but in fact, the 'Body of Aether' has quietly returned to its body, and the return of the fairy essentia structure has further enhanced Mahdi's power!

And just when the huge power was condensed on the knight's body, making his posture more and more huge and majestic, like a mountain, the dark gold dragon slowly raised its head, and its six eyes slowly lit up, getting brighter and brighter.

- Buzz! Invisible ripples began to spread, radiating in all directions!

It's coming!

At this moment, Yin Eun had a premonition that an attack was coming.

At this moment, he remembered the words of the eldest prince Carlos.

[Just be prepared...... Death will not catch up with me! 】

Remembered, and then, there was a blinding light.

The immovable fortified city that bore the brunt of the attack only felt as if a new star had exploded in front of his eyes, like a round of the sun exploding in front of his eyes, extinguishing all the darkness and the future.

Immediately after, there was an incredible 'shock' and 'collapse'!

The knight was shocked, only to feel that all the organs and souls in his body seemed to be under invisible pressure, far more than the force he originally withstood began to act on each of his cells, directly destroying it!

The Dark Gold Dragon unleashed its own attack, which was not just a light cannon or a shockwave, but a 'gravity wave weapon'!

By releasing the aether current formed by the original aether, changing the local gravitational field in the target area, creating a short-term hypergravity and high temperature and high pressure, this weapon is also equipped on the earth, and it is a 'weapon against asteroids' used by large exploration ships to explore asteroid mining areas.

This is also the truth of the Dark Gold Dragon's Breath: the breath that looks like a flame of light is essentially a gravitational beam, which can create terrifying physical shocks and high temperatures and pressures that destroy all matter.

Under the destruction of such an incredible force, the surrounding mountains, woods and rocks all began to collapse, shatter, turn into dust, and then burst into flames under the super heat, turning into a raging sea of lava and fire, but an acute cone-shaped earth with Mahdi as the source remained as it was!

Rumble! The insect hive crystal dragon heart light body at the front lasted for about a second before shattering, and the powerful energy level of the gravity wave caused it to collapse and collapse, and countless fragments were scattered with the wind, like snowflakes in a blazing fire.

And then, the invisible but scorching wave hit the Mahdi Heartlight Shield at the front, and the terrifying pressure instantly pressed the spherical Heartlight Shield into an ellipse, and then completely crushed, and the original earth and stone around it had evaporated into a bright golden-red mist, falling like rain.

In the next second, the two layers of psionic shields and the ice shield blessed by Yin En all burst into dispersion, and the layers of ripples shredded the essentia shield and electromagnetic shield of the dragon scale armor like a shock wave, and then tore apart the ultra-high temperature vapor layer blessed by Ga'er.

The sea of lava was blown into a steep cliff by the terrifying impact, a large amount of hot magma was blown into the sky, endless lava rain began to fall, and the destruction caused by gravity waves finally tore apart the psionic ornaments given by Anfa, shattered the Blood River Armament, touched the knight's flesh, and began to burn and destroy his indestructible body!

At this moment, among the fragments of the ornament, the 'Ning Mo Xiyan', which was enough to suppress all the attacks within the third energy level, had been completely extinguished, and dissipated after devouring too much energy.

Eventually, the waves of the lava sea crashed down, forming a huge impact circle, spreading out towards the periphery one by one, and the surrounding several barely existing lava mountains were engulfed in an instant.

The entire test site was destroyed by the energy blast released by the fourth energy level.

However, in the midst of this churning monstrous flames, there is still a figure standing!

[Blocked!] 】

In the second generation of the immovable fortified city, Mahdi's charcoal-like body was still standing straight, although he could no longer speak, but the essentia was shocking: [I blocked it! 】

On the knight's body, the last layer of dragon scale armor had been scorched and almost shattered, and the shields blessed by other young powerhouses were only barely existing in Aina's 'Yang Flame Protector'...... But he did block all the gravity beams that hit this place, and blocked the all-map attack that the Dark Gold True Dragon released regardless of it!

His right hand, as well as most of his body, were destroyed and ignited in the attack just now, leaving only the bones and internal organs still intact, and the whole body was covered with a charred carbon layer, and the 'etheric phase transfer' of the body of light could only transfer the attack that hit one part of the body evenly to the entire body, but the gravity beam just now was attacking the whole body, and it could not be transferred at all, it could only weaken the impact as much as possible.

The Spirit Body of the Blood River Armed was still recovering little by little, and it was recovering very quickly, at least faster than the knight himself.

It was a blow, an unprecedented blow......

- But the fortified city has done it!

Yin Eun really blocked the attack of the fourth energy level!

[This, impossible! 】

At this moment, the Dark Gold Dragon used up all the primordial ether she had just refined, and she was indeed in the 'period of weakness' predicted by the prophet, and she couldn't help but show a stunned gaze: [How is it possible...... Can this be blocked?! 】

- How could it not be?

At this moment, the people who had been guarded by the Immovable Fortress stepped out from behind Mahdi, and they silently crossed Mahdi's body, and then stood in front of the knight.

】

The feeling of being guarded...... What is it? Is it peace of mind? Is it happiness? Or is it a feeling of gratitude?

No...... Neither. For these arrogant young generation heroes, the feeling of being guarded is only shame.

Only shame washed away with blood!

Rumble!

！

At this moment, with the violent aether fluctuations, the bright bright light bloomed, and they had completely urged the final power of their hole cards...... Bursts of light lit up, and various colors of essentia spiritual energy exploded, flooding the entire testing site with rainbow light, illuminating the expressionless dragon head of the dark gold dragon and the knight's figure.

- That's ...... Immovable Fortified City!
