In the sea of knowledge, the soul of the rat clan didn't know if it was too fierce and vicious, or because of the heavy blow to him in the eyes of the black abyss, the four hooves stood in the sea of knowledge, setting off a monstrous wave, and his rat body also became four or five meters huge, and the flames around his body were soaring, permeating the range of ten meters, and the rat's mouth also let out an angry and screaming sound.

Xu Feng frowned slightly in the air, he didn't know what was going on with this rat soul? But as soon as he reached the air, the rat soul sensed himself, and actually raised his head and roared fiercely at him, a terrifying sound wave swept in, he hurriedly stretched out his right hand, held it in the air, and a wind sword condensed out, and then, he held the wind sword with both hands, stirring violently against the rushing sound waves, and finally, formed a sword wind tornado. He stabbed out with a sword, and the sword wind tornado, like a dragon, slammed out, and crashed into the terrifying sound wave, and the sharp sword wind tore the terrifying sound wave, but he still underestimated the origin power of the soul of the rat clan, and the terrifying sound wave actually carried the power of devouring, and he was busy retreating like lightning, and finally, avoiding the remnants of the sound wave.

However, the giant rat soul lying on the surface of the water stepped on the surface of the water violently, trampling the surface of the water out of a large crater of water waves, while the rat soul soared into the air and pounced like a black shadow.

Xu Feng didn't dare to be careless, he knew that this rat soul was here to compete with him for control of the body, how could he let him get his wish, seeing that the rat soul was carrying a rolling devouring flame, rushing towards him, he also swung his wind sword in the air, and the sword domain surged out, covering his five-meter range, and there was no way to avoid it, and he also pounced in the air.

In the end, Xu Feng and the rat soul collided hard, and the sword domain and the devouring domain collided with each other and the sword wind devouring flames flew everywhere, and Xu Feng and the rat soul also flew out upside down one after another, however, at the moment of stabilization, they flew towards each other again, and fought wildly.

Xu Feng had to hold the wind sword, and in the face of this dark rat soul, he continued to swing out the traceless sword wind to slash and destroy those flame-devouring spirits, however, this rat soul was obviously wild and vicious, and it was still a spirit realm-level rat soul, stronger than him, therefore, in the face of the sharp teeth of this rat soul, and the claws were clapped, Xu Feng had to avoid its edge, and used the traceless sword wind to slash at the sharp teeth or claws, and also flew out upside down with his strength, and at the same time, he also used the soul devouring technique to slash and stir up the flames, constantly devouring and fueling his sword domain.

In fact, now he understands that if he wants to defeat this rat soul, he is afraid that he must defeat the other party in the domain now, otherwise, in the absolute domain, he will be tied and unable to defeat the other party at all, therefore, Xu Feng avoided its edge while using the soul devouring technique to devour the flame devouring soul power that flew out, and this rat soul, he also saw it, and he also knew the soul devouring technique, and he was also devouring his sword domain soul power, but it was not active, but instinctively when attacking himself, his power was scattered, and it was absorbed by the way, not at all like Xu Feng's active and deliberate absorption。

Therefore, Xu Feng was defeated in front of this rat soul at the beginning, and he had to retreat as an advance and fight fiercely with the rat soul, but as the battle deepened, Xu Feng gradually moved back to a disadvantage, after all, before this, in order to fight against the terrifying existence in the soul cave and escape, the flame devouring domain of the rat soul had been forcibly integrated into his sword domain, and he already understood some of the mysteries of the devouring domain, but he didn't have much time to comprehend, and he was suddenly forced too tightly by this rat soul, so it would be like this.

Gradually, in the five-meter cyan sword domain, it gradually turned black, and wisps of black flames evaporated from the sword domain, as if they were wisps of flames, and the power of the sword domain seemed to be increasing......

Xu Feng watched the rat soul kill again, but he bit the wind sword in his hand, he hurriedly stirred up the terrifying sword wind, and he didn't even break away from this sharp mouth, instead, the flame-devouring flame on the rat soul's body suddenly burst up, and a flame-devouring giant hand emerged from the devouring domain and grabbed it towards Xu Feng.

Xu Feng had no choice but to let go of the wind sword, quickly dodging the back, and at the same time, his left hand also turned over violently, and the pale black flame in the sword domain instantly appeared, and also condensed a flame-devouring giant hand, of course, there was also the sword wind rippling, boom, the two flame-devouring giant hands collided together, but a huge energy fluctuation erupted, Xu Feng was shocked out on the spot, and it didn't stop until hundreds of meters into the sky, and the rat soul was also shocked back more than ten meters, and his heart was very happy, this rat soul didn't seem to be as strong as those god-devouring rat souls standing proudly in the air, but it should not be underestimated。

The rat soul pounced again, and three more flame-devouring giant hands emerged from his back, rushing in with lightning speed, trying to catch him, but Xu Feng instantly stepped out of the six divine steps in the air, avoiding these flame-devouring giant hands, and swept out a traceless sword wind with a sword, slashing at one of the flame-devouring giant hands, as if slashing on the quagmire, and then, the infiltration actually melted, and his face changed slightly, why did the dark origin of this rat soul become stronger and stronger? And the fierce light in the eyes of this rat became deeper and deeper, and it seemed to feel that Xu Feng was not fighting with him for the sovereignty of the flesh at all, but was completely for his devouring domain, so he screamed wildly. In the devouring domain, two flame-devouring giant hands suddenly shot out, and they stretched out more than ten meters in an instant, and instantly grabbed Xu Feng, who was seven or eight meters away, in his hand, and pinched it completely, feeling that his soul was about to be pinched and exploded, and he screamed miserably.

Xu Feng was furious, desperately trying to break free from this flame devouring giant hand, as a result, just freed his hands, the lower half of his body waist was still pinched by the flame devouring giant hand, and he also felt that the soul power was burning with this flame-devouring power, quickly draining, and integrating into the devouring domain of the rat soul, which shocked his face ugly, and he was busy with his hands to fly, and in an instant, the soul dementor that stopped in the far sky of the sea suddenly appeared on the top of the rat soul's head, and in an instant, the gourd mouth slowly rotated, sprinkling the light of the soul dementor, and enveloping it in it.

The rat soul also seemed to feel the huge power of the dementor, and suddenly let out an angry cry, and the flames around it rose into the sky, however, the awakened soul dementor spirit was by no means something that the current rat soul could compete, and even Xu Feng was a little powerless, so the flames that pounced on the soul dementor were suddenly devoured into the gourd.

And Xu Feng also took the opportunity to condense a mouth of the wind sword again, with an angry shout, the wind sword was fiercely inserted into the flame devouring giant hand, and the traceless sword domain erupted again, instantly destroying the flame devouring giant hand, freed from it, panting fiercely, looking up and seeing the rat soul, shrouded in the soul light, the left picture rushed to the right, but it was not out of the range of the soul light, but it was not swallowed by the soul gourd, which slightly relieved him.

However, this rat soul is a big threat to him, and he can't defeat it for a while, just like other god-devouring rat soul bodies, but this one has its own soul, Xu Feng held the wind sword, and came to the outside of this soul-dementoring light in an instant, the wind sword stabbed into the soul light, and also pierced into the body of the rat soul, the soul devouring technique ran wildly, this rat soul screamed, went crazy, pulled out the wind sword on his body, but hit the soul light on the opposite side, and was almost shocked, and was pierced into the soul body by the wind sword again, and was devoured soul power.

It's a pity that Xu Feng was very interested in the mystery of this rat soul's devouring domain, so he took the six divine steps, lightning quickly, came to his side, and pierced the body of the rat soul with the wind sword, devouring his flame-devouring power, so several times, this rat soul seemed to gradually calm down from the irascible and wild killing, knowing Xu Feng's strategy, he was busy lying in the center of the soul light, motionless, and not thundering, and the flame-devouring flame on his body was also included in his body, not letting it be devoured.
