After being promoted to the fourth level, the black crystal on Xia Feng's body finally completed the final transformation, and truly evolved into a set of hideous battle armor, making him look like an ancient god of war, and his defense power reached a new realm, and the five-colored light blade that could cut through the third-level zombies could not hurt him at all.

"Big peacock, you've been tickling me for so long, it's time for me to thank you."

A loud voice sounded from Xia Feng's mouth, and after reaching the fourth level, he finally regained his ability to speak, and bid farewell to his mute life, and as he spoke, one after another fiery red lines spread from his chest to his whole body, quickly completing the transformation of the fire pole, and the blazing flames also rose from around his body, turning the nearby five-colored light blade into flying ashes.

"Red Dragonfire!"

Xia Feng let out a low cry in his heart, and with a wave of his palm, a fireball the size of a millstone condensed out, going upstream, dispersing the five-colored torrent, and heading straight for the mutated peacock.

"Wow!"

The mutated peacock let out a sharp chirp from its mouth, and the brilliant five-colored light in the sky suddenly contracted, and it actually converged into five crystal swords of different colors, emitting five kinds of light, gold, blue, red, green, and yellow, and slashed towards the blazing fireball.

"Boom!"

The five small swords, which seemed to be only one meter long, showed the slightest powerful power that did not match the volume, easily slashing the fireball the size of a grinding disc and extinguishing it, and then attacking Xia Feng unabated.

Seeing this, Xia Feng immediately picked up Zixiao on the side and greeted him, colliding with the golden sword that rushed to the front.

"Ding!"

A piercing sound sounded from the place of collision, the seemingly small and delicate golden sword contained terrifying power, thanks to the blessing of the God of War bracelet, Xia Feng barely shook it out, but at the same time, the other four crystal swords also came towards him menacingly.

"Get out of here!"

Xia Feng roared angrily, and the purple sky in his hand suddenly swept out, and the terrifying power made a whining sound in the friction with the air, directly sweeping the four crystal swords out at the same time.

But at this moment, the golden sword that was shocked by him just now flew back upside down, and slashed directly at Xia Feng's ribs at a tricky angle, although Xia Feng reacted extremely quickly and twisted his body, but it still inevitably left an inch-deep wound, and the battle armor that could resist the five-color light blade was like paper paste at this moment.

The return of the golden little sword was just the beginning, and after the other four small swords drew a graceful arc in the air, they also flew back one after another, leaving several wounds on Xia Feng's body.

", we all rely on mutation, you are an immortal cultivator!"

Xia Feng looked at the five crystal swords flying around him, and couldn't help but scold, and at the same time moved Zixiao to move, even if he couldn't block the attack of the five crystal swords, but at least he had to protect his head.

Of course, it was not Xia Feng's style to sit back and wait for death, when he resisted the crystal sword, the zombie troops equipped with the Extreme Ice Cannon also aimed their muzzles at the mutated peacocks in mid-air, and pillars of azure light burst out from the muzzles, forming a firepower net, enveloping the mutant peacocks.

The mutated peacock, who controlled the five crystal swords, seemed to have no strength left to release the multicolored light blade, and could only flap its wings to dodge left and right, avoiding the attacks of the ice pole cannon as much as possible.

But under Xia Feng's order, as long as the spar inlaid with the ice pole cannon was not exhausted, they kept shooting, although the mutant peacock tried its best to dodge, but under the distraction of controlling the five crystal swords, they were still hit by the ice pole cannon one after another.

However, the strength of the mutant peacock is far from that of those ordinary mutant birds, and the pillars of blue light fall on its feathers, only blooming a few ice flowers and producing a thin layer of hoarfrost.

But even so, it made the mutant peacock feel extremely angry, and a sharp chirp came out of his mouth, and he actually abandoned Xia Feng and controlled five crystal swords to slash towards a hundred artillery zombies.

Even Xia Feng's crystal small sword, which he couldn't resist, killed ordinary zombies, it was like chopping melons and vegetables, and he could easily harvest more than a dozen zombies with a single slash.

But as the five crystal swords were raging among the artillery zombies, Xia Feng had a chance to fight back, but the mutated peacock was flying in the air at this time, and ordinary means couldn't even touch him.

Seeing that the mutant peacock had slaughtered a hundred artillery zombies, and was about to target him again, Xia Feng was in a hurry, so he casually lifted an ordinary zombie beside him and threw it directly at the mutant peacock as a hidden weapon.

With Xia Feng's current arm strength, it is not an exaggeration to regard this ordinary zombie as a cannonball, and in the blink of an eye, it spanned a distance of more than ten meters and smashed into the abdomen of the mutant peacock, and the terrifying power smashed its body trembling, and it turned out two heels in the air in a row before stabilizing its body.

Seeing that this trapeze had a good effect, Xia Feng simply thrust Zixiao into the ground, opened his bow left and right with both hands, and kept smashing the zombies towards the mutated peacock.

Although it didn't cause any substantial damage to the mutant peacock just now, it successfully attracted its attention, and the five crystalline small swords were recalled by it to form a sword net in the air, and the light flickered, cutting all the zombies that smashed at it into several pieces.

But Xia Feng had had enough of being pressed and beaten, and finally seized the opportunity, but he was even more unwilling to give up, and still threw zombies towards the mutated peacock, not only him, but Long Xiang, who had recovered a lot of strength, also joined in, and kept smashing the zombies at the mutant peacock like him.

Between the two sides, attacking and defending, they strangely maintained their balance, and slowly stalemate, and time passed quietly in this duel, and in a blink of an eye, more than ten minutes passed, but the scene still remained unchanged.

I thought that even if the mutated peacock was a cultivator, it would be impossible to control the five crystal swords all the time, but after more than ten minutes, the mutant peacock did not show any fatigue, but had a feeling of becoming more and more courageous.

And now the air supremacy has always been in the hands of the mutant peacock, and now it wants to protect the nest and is reluctant to leave, but it is really a dangerous moment, as long as it flapps its wings and flies into the air, then Xia Feng can only stare dryly on the ground.

Xia Feng didn't want to fight a battle that was destined to be fruitless, and he didn't want to leave an enemy to stare at him in the air every day, and he couldn't eat or sleep in peace, so he kept thinking about a good way to settle the battle in his mind.

And when he saw Long Xiang who was throwing zombies hard out of the corner of his eye, a bold idea suddenly came to his mind, and he immediately moved his steps, throwing zombies while slowly moving towards Long Xiang.
