"Roar!"

The gray-mouthed iron dragon let out a solemn roar, flapping its wings and speeding up into the air.

Piero Grayiron, the Duke of Gray Iron standing on its back, suddenly had some doubts: "Gray King, what's wrong?"

"Roar!"

Unable to speak, or to connect with Piero's psychic path, the Grey-Mouthed Dragon could only barely communicate through its body language and the dragon's moans in different tones. Fortunately, although Piero is not a dragon knight, he has been fighting with the gray iron dragon since he was a child, and he somewhat understands what it means.

"You're saying we're in danger...... Is it the invisible dragon from before?" Piero quickly guessed the truth.

"Roar!" the Grey Iron Dragon confirmed.

Piero's face suddenly sank: "The invisible dragon knight, Liszt Flame, is this following us all the way, and when he sees me flying alone, he wants to attack me?"

"Roar!"

"Gray King, can you stand up to the Invisible Dragon Knight?"

"Roar!" the Grey-Mouthed Dragon replied with a domineering voice, then spread a few scales from his back and motioned for Piero to duck under the scales.

Next, it's going to face the battle alone!

The wings that covered the sky and the sun flapped over the clouds and climbed higher into the sky—it was afraid that the sea water raised by the sorcerer would trap it. Dragons, such high-IQ creatures, naturally understand that the sky is their battlefield, and the higher they are, the better their chances of winning the battle.

By the time it climbs to an altitude of 20,000 meters, the air is already very thin.

Although the gray-mouthed iron dragon did not feel uncomfortable, it did not continue to climb, and it was difficult for Rao to climb higher in the sky with the posture of a dragon.

Slowly hovering high in the sky, he closely felt the invisible dragon magic aura that was getting closer and clearer around him.

Its body appears strong and powerful, with steel-gray scales reflecting sunlight and a natural coolness of metal. The tail appears slender relative to the body and constantly flicks behind the tail. There is a slight protrusion at the tip of the tail, like a dragon lance that will bend, ready to attack at any time.

However, to the uneasiness of the Grey Iron Dragon, it clearly felt the magic aura of the invisible dragon, but it was unable to lock the position of the other party.

Moving left and right, forward and backward, up and down, makes it feel that it is not against a single dragon, but that there are countless dragons hiding around.

Of course.

The Gray Iron Dragon knew that the other party was not only an invisible dragon knight, but also a fire dragon that could appear at any time, and a powerful magician—it was only in order to avoid the magician's attack that it had climbed 20,000 meters into the air.

"Roar, roar, roar!"

Time passed minute by minute, the invisible dragon still did not appear, and the gray-mouthed iron dragon was already restless.

Even Duke Piero, who was hiding under its scales, was extremely uncomfortable, and the air here was so thin that he couldn't breathe. If it continues, maybe he will become the first monarch to be suffocated.

But the invisible dragon just doesn't appear.

It's just constantly changing directions, teasing the willpower of the gray iron dragon.

Occasionally, it would disappear for a moment, and when the gray-mouthed iron dragon tried to evacuate, the magical aura slowly approached again, and the invisible dragon went to tease around it again.

The whole process went back and forth and lasted for two hours.

It made Piero so blue that he couldn't help but beg the gray iron dragon: "Gray King, I'm about to suffocate to death, let's evacuate to the coastline quickly!"

"Roar!"

The gray-mouthed iron dragon was not reconciled and ignored Piero. So another hour passed, and when Piero passed out due to lack of oxygen, the gray iron dragon was still high in the air. It's just that at this time, although Piero did not continue to make noise, its own spiritual will had endured to the limit.

The nerves were tense in the face of danger and excitement for three hours, and the body did not get any rest, and it was no longer possible to sustain it.

The state suddenly collapsed.

"Roar!"

With a furious dragon groan, the gray-mouthed iron dragon flapped its wings and flew away without turning its head back towards the shoreline.

But just when it couldn't help but turn around and run, the invisible dragon that had been secretly teasing finally appeared. Liszt, who was already ready to attack, held the fury of thunder, poured the violent magic and fighting spirit of his whole body into the tip of the dragon spear, and quickly struck out with a move "Snow Mountain".

The Grey-Mouthed Iron Dragon's reaction was not unpleasant, but after all, it had collapsed once, and its tail was a little slower when waving its tail.

Brushing the invisible dragon's body, it missed, and then there was a tingling pain above the thigh on his side, and the furious attack of Thunder Fury had already struck firmly on it. Breaking through the incomparably hard steely scales, the scorching fighting energy and cutting magic exploded wildly, crushing several vital muscles at the base of the thigh.

Without waiting for the gray dragon to turn around and fight back, Liszt pulled out the fury of thunder, and let Ark casually throw an ice shield to block it, harnessing the invisible dragon Bard and escaping into the material boundary again.

The gray-mouthed iron dragon turned and bitten.

And spit out a torrent of metal dragon breath, turning into countless blades to shatter the ice shield, but it can't hurt the invisible dragon in the slightest. The Grey-Mouthed Dragon wielded its magic, solidifying the wounds at the base of its thighs and erecting its scales, arming itself into a steel hedgehog-like figure.

The iron dragon does not have the copper-plated state of the copper dragon.

It can only set up scales to form a hedgehog formation and protect itself.

But this was doomed to be a futile attempt, as the scales blocked the passage of air, slowing it down considerably. So the invisible dragon rushed out from time to time, stabbed and escaped into the material border. Every time a shot is shot, a piece of dragon blood will inevitably explode on the gray iron dragon.

"Roar, roar, roar!"

The gray-mouthed iron dragon was annoyed, and what made it even more afraid was that its state was getting weaker and weaker, so the psychology of escaping became more and more dominant.

Sometimes when you are hit by a critical shot from Liszt, you have to fly forward desperately. It was as if you could fly for a while and reach land, and then you would be safe.

However, Liszt, who was chasing after it, smiled proudly: "The mentality has collapsed, at this time, in this state, turning around and fighting back can still cause me a heavy blow, in addition, you can't escape if you want to!"

The dragon spear dances, and the fighting spirit is furious.

Liszt showed and verified all his thoughts on "The Invisible Dragon Knight - Dragon Fighting Qi Cheats" in the pursuit battle, ghost-wipe, shadow-flirtation, snow-mountain-avalanche, sonic boom-sting, poisonous dragon-diamond, as well as some new inspirations that had just formed ideas and had not yet begun to be polished.

"Woohoo!"

Bard was equally excited, its slender body chasing the huge Grey-Mouthed Iron Dragon, and the contrast in power thrilled it. He didn't even need to spit out the dragon's breath, he directly used his claws to leave traces on the gray-mouthed iron dragon - the dragon's breath was closely related to the dragon's origin super demon, and it hurt his body if he vomited too much.

So.

Liszt's dragon lance and fighting skills, Bard's dragon claws and bites, and Ake's ice shield and water knife constantly inflict damage on the Gray Iron Dragon, and the whole process is even easier than killing the Bronze Dragon Knight Loyle in a hurry - because there is a very quiet output environment throughout the whole process.

No dragon knight could come to the aid of the Grey Dragons in a short period of time.

One chases and one runs.

Bloodshed all the way.

After chasing dozens of kilometers in an instant, the gray-mouthed iron dragon finally saw the coastline of the Eagle Kingdom, and it mustered the strength of its whole body, endured the pain all over its body, and wanted to return to the land in one go.

"Roar, roar, roar!"

As long as it lands, there is hope for a turnaround.

Reality wouldn't let it go, and Liszt reappeared, and the dragon lance struck its body hard. Bard also spat out a mouthful of dragon's breath that he was reluctant to spit out, cutting its scales as he kept slicing. Acker's vector cut was unleashed at the same time as the high-pressure waterjet, breaking through its broken scales once more.

And then.

What made the gray-mouthed iron dragon most desperate was that a flame bloomed in front of him, turning into a fire dragon with a wingspan of about thirty meters and black and red scales all over its body. Beneath the fierce horns and twisted scales of the fire dragon were a pair of scarlet eyes with infinite evil.

It's like looking straight at death!

Without any superfluous movements, the fire dragon collided with the gray-mouthed iron dragon fiercely!

For a moment, both dragons made the sound of bones breaking, and both lost their balance and fell to the sea. It's just that the fire dragon Leo has plenty of time to regain his balance, but the gray-mouthed iron dragon is facing a stormy blow from Liszt, Bard, and Acker.

Take advantage of his illness to kill him!

This is Liszt's consistent life motto, the character who likes Gou on weekdays has reached the moment of battle, but he has become an African flat-headed brother, and he will do it if he is not satisfied with life and death.

Besides, how can you not grasp the opportunity to beat the water dogs!

"Gray Iron Dragon, mine!"
