Although there was a light blue light curtain on the mechanical giant's body that blocked the impacting leyline red flames, so O'Connor was not harmed by it, but he knew very well in his heart that he could not extinguish these strange red flames, so naturally he did not go in vain to rescue his men.

"Retreat. A loud metallic sound rang out from the mechanical giant, and at the same time, the mechanical giant's right hand reached out of his leg, and he pulled out a huge shotgun.

For a mechanical giant, this is just a gun, but for ordinary people, it is definitely more like a huge cannon, with a muzzle diameter of seventy or eighty centimeters alone.

The shotgun was obviously already loaded, so the mechanical giant didn't hesitate to pull the trigger after grabbing it in his hand.

"Boom. With the thunderous explosion, countless huge projectiles erupted from the muzzle of the gun, roaring towards Chen Feng like a raging storm.

At this moment, Chen Feng actually felt a strong sense of danger, because the projectiles not only possessed powerful kinetic energy, but also condensed a large amount of heaven and earth aura around them.

It's just that these heaven and earth auras are disorderly, and they are furious as if they are stormy waves, and they swept towards Chen Feng with the momentum of destroying the heavens and the earth. There is a posture of crushing it into pieces in an instant, and then bombarding it into slag.

......Under the urging of Chen Feng's spiritual sense, the Qingmei Sword flew rapidly in the air, flashing out long or short, curved or straight sword lights, as if they were intertwined into layers of impermeable sky-covering giant nets in an instant, and fell towards the roaring projectile.

"Bang Bang Bang ......" Under the collision of the sword light and the projectile, a deafening explosion suddenly erupted, and when the projectile shattered, the aura of heaven and earth around it also collapsed.

The destructive power that erupted from the already chaotic heaven and earth aura colliding with each other at this time was undoubtedly quite amazing, it was like detonating a huge bomb in the already frantic and boundless undercurrent, and the heaven and earth aura within a radius of more than a thousand meters became extremely violent, the wind was loud, the air was squeezed, and there were explosions one after another, which was shocking and abnormal.

Chen Feng, who was falling from the air, was hit by the shock wave, and couldn't help but be like a leaf in the wind flying out backwards.

Fortunately, he now has A-level strength, even if he can't fly in the air, but under the flickering of his body, he can skillfully defuse the oncoming impact.

But O'Connor's attack came again, and with a loud bang, the huge shotgun in the mechanical giant's hand opened fire again.

The silver-white sword light flickered rapidly again, instantly slashing the countless projectiles as before, and at the same time, the Red Flame Dragon Ball also flew in front of him under the traction of Chen Feng's spiritual sense, releasing blazing flames to resist the sweeping shockwave.

Chen Feng had just landed steadily on the stone steps at this time, but he was only less than half a meter away from the edge.

If he hadn't had the Red Flame Dragon Ball to help him block the impact just now, then he would most likely have fallen off the stone steps. Below, however, there is a rift valley hundreds of meters deep.

Even if Chen Feng was able to summon the Qingmei Sword to hold himself up, in that case, he would inevitably lose the first move in the fight with O'Connor, and he could only see the moves, completely falling into a passive situation.

In fact, the current situation is still not optimistic for Chen Feng.

When combined with modern guns, the consistency of the attack and the burst of attack power are undoubtedly terrifying. At least Chen Feng, who was not used to this way of fighting, was temporarily at a disadvantage.

"Bang Bang ......" O'Connor was able to become the director of the Super Energy Bureau, not only with strong combat power, but more importantly, with extraordinary eyesight.

As soon as he saw that he had a slight upper hand, he immediately pressed forward step by step, wanting to continue to expand the results.

The mechanical giant stepped forward and walked towards Chen Feng, but the shotgun in his hand was firing again and again. The dense projectiles bombarded Chen Feng like a metal storm.

Chen Feng didn't block hard this time, but didn't wait for the projectile to fly in the near future, the sword had already taken off into the air, and it was directly out of the attack range of the shotgun, but the Red Flame Fire Dragon Ball was bursting with firelight, and the blazing and extraordinary leyline Red Flame was like a huge wave of layers and rushed towards the roaring projectile.

......Hundreds of projectiles burst instantly, and the scattered fragments were directly melted into red droplets by the red flames of the leylines, which were particularly dazzling in the dim light, as if they were bursting fireworks.

The ensuing shock wave formed by the collision of heaven and earth auras collided with each other collided with the leyline red flame again, making a deafening loud sound.

In an instant, the flames swept and the wind roared, as if two fierce ferocities were fighting wildly, and the impact pushed the mechanical giants back a step.

......When the sword light flickered, Chen Feng, who came from the sword, had already appeared behind the mechanical giant after making a circle, moving his fingers like a sword, and the different sword qi was already swarming.

After seeing O'Connor's strong combat power, Chen Feng naturally did not have any more strength left, and under the crazy agitation of the true yuan in his body, thirty-two swords were released in an instant.

Now Chen Feng, who has A-level strength, has as many as four kinds of sword intent that he has cultivated, and now with all his strength, it is really a sword qi that is vertical and horizontal, and the sword intent is agitated, and it has the potential to tear the void and cut through the sky.

The fastest and most agile nature is the sword intent of electricity, and the most ferocious and violent is the sword intent of thunder, and at the same time, thunder and lightning are never separated, the sword qi under these two sword intent will collide with each other from time to time, not only do they cancel each other out, but there is a great power to borrow thunder, thunder to help the electric power, not only the trajectory is changeable and more powerful.

The lightning and thunder continued to burst out as the sword qi swept through the air, constantly crossing like a zigzag electric snake, and finally like a dense network of thunder and lightning shrouded towards the mechanical giant.

The sword intent of the sea that followed was turbulent and agitated, especially under the continuous accumulation, it had the power to sweep the heavens and the earth.

However, the equally fierce Fire Sword Intent was the most changeable, the reason was that Chen Feng had now absorbed two completely different flames, the Earth Vein Red Flame and the Taiyin Ice Fire, the former was blazing, the latter was extremely cold, and under the collision with each other, the cold and heat alternated, and there were countless changes.

......In a hurry, the mechanical giant didn't have time to turn around, but the cannon on his shoulder had already turned its muzzle and began to vent its firepower frantically.

It's just that before there were many shells, more than ten sword qi had already stabbed in front of them, directly stabbing those shells that had just been discharged, and the powerful shock wave and shattering shrapnel swept around, of course, it also affected the nearest mechanical giant.

Even though the mechanical giant was surrounded by a layer of blue light, which could block the dense shrapnel, the strong impact could not completely cancel it out. This will inevitably affect the speed of its body's rotation.

"Boom, boom. At this moment, the intertwined electric light and thunder also bombarded down.

The blue-purple light exploded directly outside the mechanical giant's body, constantly impacting the blue light mask, causing ripples layer upon layer.

At the same time, the intricate runes on the mechanical giant's body were constantly flickering with light, and they looked very dazzling, but O'Connor, who was inside the mechanical giant, was not in a good mood, because the sharp alarm kept ringing in his ears.

O'Connor was well aware that this meant that the elemental energy that kept the mechanical giants running was being depleted dramatically. If this continues, his mechanical warframe will soon be unable to maintain its current combat form.

For him, this is undoubtedly a pretty bad thing.

In addition, what made O'Connor frown even more secretly was that under such a firepower catharsis, the amount of ammunition carried by the mechanical warframe was also rapidly decreasing.

For O'Connor, who has always believed in the supremacy of firepower, this is also not good news.

"Looks like we're going to have to end this fight as soon as possible. O'Connor thought to himself, the killing intent grew stronger.

At this time, O'Connor, who was wearing a mechanical armor, had just turned around, but before he could pull the trigger of the giant shotgun in his hand, he couldn't help but curse damn it.

Because the furious sword qi had swept near.

Although O'Connor may not have understood the magic of the sword moves that Chen Feng used at this time, he could still see the great power of the sword intent like the waves of the sea.

What's bad is that now he has no chance to dodge at all, and all he can do is a hard top.

"Boom, boom...... Bang bang bang bang ......" O'Connor pulled the trigger again and again without hesitation.

The shotgun, which was not known for its rate of fire, felt like a submachine gun was fired by him, and the impermeable projectile slammed into the sword qi like an enraged swarm, and exploded with an earth-shattering loud noise.

The next moment, a storm of metal, heaven and earth aura, and sword qi intertwined appeared between Chen Feng and the mechanical battle armor, and the three collided wildly, crushing each other, and the resulting shock wave also spread in all directions wave after wave.

Because this shock wave was so strong, that the huge mechanical battle armor was knocked back again, but Chen Feng, who was in the air, did not move.

It was only because the sword qi containing the sword intent of fire directly dispersed the shock wave that swept towards Chen Feng, and the sword qi did not decay at all, breaking through the layers of shock waves and bombarding the mechanical battle armor.

"Boom. With a loud bang, the blue light shield on the outside of the mechanical armor flickered rapidly and suddenly became much darker.

At this time, the runes on the mechanical battle armor lit up one after another, and the surrounding heaven and earth aura began to continue to surge towards the mechanical battle armor in order to replenish the previous violent consumption, but the originally very bright blue light shield could not quickly return to its original appearance.

"Even though it's huge, it seems that there is a limit. Chen Feng thought to himself, his fingers flicked rapidly, and in an instant, sixty-four sword qi burst out.
