Under the invisible sword mountain, Mu Ziyun stretched out a claw from the ball of fire slurry, and the claw was filled with dense fire qi, and then an infinitely extended fire knife stabbed out.

The fire knife continued to lengthen, and a large amount of fire slurry appeared on the knife body, and when it was a hundred zhang long, Mu Ziyun held this hot fire knife, and with the fire qi that surrounded him, he began to lift it from the bottom, and the invisible mountain that was pressing him was divided into two.

Taking advantage of this opportunity, Mu Ziyun sprinted out of the slit, the flames on the fire skull fell on his back in the sprint, and the two burnt claws, each grasping a fireball a few feet wide, first threw a fireball to open the way for himself, and followed closely behind, ready to give the old sword king a frontal impact.

Unexpectedly, on the way to the old knife king, unimpeded, the old knife king's eyes did not blink, he raised his chest with a condescending posture, and stubbornly caught the impact of Mu Ziyun's two fireballs, the scars on the old knife king's body roasted by the flame were very hideous, the dark skin burned and extinguished and burned again, and the end was nothing more than adding a hundred and ten scars, for the old knife king, this level really did not arouse his interest.

"Hey," the old sword king said in a deep voice, "Little ghost, take a look at your best skills." Then he inserted the big knife in his hand casually, and the white rune array appeared instantly, catching the big knife. Spread out his hands, the old knife king had an attitude of letting you fight and let you shoot.

Mu Ziyun couldn't help but be furious, retreated more than ten zhang away, grabbed his hands from front to back, and there seemed to be a space distortion in front of him, and then compared his hand to his mouth, and suddenly spit out the pillar of fire, the old sword king was in the flames and did not move at all, he didn't even close his eyes, Mu Ziyun's heart moved to let the fire beads fly to his mouth, and in an instant, the range of the pillar of fire expanded by more than four or five times, and the color of the flame turned red.

At this time, the old sword king's face was no longer so calm, his body arched slightly, and his feet were staggered by a foot back and forth, and he was slowly pushed backwards by the fire under the improvement of the entangled magic qi to protect himself.

"This fire..."The old sword king was already a little unable to open his eyes, and he didn't bend it, so he immediately pulled out the big knife from the rune array and blocked it in front of him, the flames were cut by the blade, and the blade was burned red, "This fire... Not right...."

The old sword king raised his tall sword and slashed down, slashed out the Dao silver blade, and flew towards Mu Ziyun's body in the face of the flames, and Mu Ziyun immediately fled to the side with the fire beads.

"My knife will not change color if it is burned in an iron furnace for 1,800 years, little ghost, your fire is quite strange, it is stronger than all the fires I have ever seen in my life, how the hell did you do it."

The flames on Mu Ziyun's head slowly melted, his eyes were scorched yellow, there were zigzag cracks from his eyes to his ears, and there was a red light flashing in the cracks, "Old man, my fire is not an ordinary fire, it is stripped from my heart, don't say that your knife, even if you are a mountain, I can dissolve it for you." ”

"It's not a small tone!" The old sword king shouted, holding the big knife and waving it from south to north, and then kept making circles above his head, and the countless invisible blades formed an inverted mountain peak above the old sword king's head in a spiral shape, "It's a pity that such a talent is not in my Bu Pumen, but fortunately, you came to die in person, so as not to bring trouble to my sect in the future." ”

"Old man, don't you Bu Pumen only practice spells, I think your technique should be regarded as a martial art." Mu Ziyun's right hand pressed the hunting bow pinned to his waist.

"Rat's eyes, 'art' is the embodiment of transcending the realm of mortals, there is no distinction between martial arts, it is just a boring title made by secular people who want to distinguish categories, don't think that standing at the same height, you think that you can be in the same realm as me, you-far behind!"

The old sword king's arm spun suddenly, and the thunderbolt drove the invisible blade chain to slash in the direction of Mu Ziyun.

With a thud, Mu Ziyun disappeared, leaving only some broken flames in place, after a breath, the back of the old sword king suffered a strong impact, and a fire claw was trying to penetrate into his body, obviously failed, the magic qi attached to the body of the old sword king was not simple, but the fire claw only stopped for three breaths, and then disappeared again.

This time it was the abdomen of the old knife king that was beaten, the meat there was much softer, and as soon as the fire claws touched it, it could sink into it a few points deep, the old knife king saw Mu Ziyun's claws, and while pulling down the blade, he reached out to grab it, and pounced, without giving him any chance, Mu Ziyun disappeared again.

"Hunt for the Bow!" The Old Sword King raised his voice, "I can't imagine that the treasure that the Hundred Refining Soldiers risked their lives to go to the Tiannu Cemetery to find is actually on your little ghost, good, good!" You've got me a great gift! ”

With a whoosh, the old sword king's shoulder was stabbed by a silver arrow, and the body of the old sword king, which could not be harmed no matter how Mu Ziyun's fire invaded, was easily pierced by this silver arrow.

Mu Ziyun didn't expect the old sword king to recognize the hunting bow, and he didn't expect the hunting bow to be so strong, so he found a breakthrough at this time, Mu Ziyun couldn't see the knife mountain above his head, and it was okay at first, but when the mountain came down, Mu Ziyun had to use all his strength to protect himself with flames, at that time, he could only defend and not fight, and he was completely passive.

As the saying goes, guns are easy to dodge, dark arrows are difficult to prevent, the old knife king can use an invisible blade to cause damage to Mu Ziyun without pressure, and with the hunting bow, Mu Ziyun can also hide in the dark, both of them have the means to hide, so it is really wonderful to fight together.

The range of the hunting bow was within twenty zhang, Mu Ziyun first hid his body and ran out of a hundred zhang away, at this time, the old sword king held the knife in both hands, wielding a mountain of blades like waves, wave after wave from the sky to the earth, each blade was close to the hundred and ten pieces, without any gaps.

Boom! Sou...... Like the sound of fireworks rushing into the sky, a meteor flame drilled into the knife mountain, and in a very short period of time, a curved arc was made, and then at the place closest to the old sword king, Mu Ziyun appeared with a hunting bow, and three silver arrows were fired together, and at the moment when the arrow came out, Mu Ziyun had fled back for nearly half the distance, and the remaining road began to be blocked by the blade that was pressed down, and Mu Ziyun simply stopped halfway, creating a big fireball to wrap himself.

The old sword king pulled out the silver arrow inserted in his body, the silver arrow disappeared not long after he held it, and returned to the hunting bow in Mu Ziyun's hand, the old knife king had not tasted the taste of being penetrated for a long time, licked the fresh blood, held the big knife in his right hand, and struck hard to the side with a fist in his left hand.

It seemed to hit the wall, and with a bang, a white rune array appeared in front of the left fist, and a big knife slowly appeared in the rune array, one pulled out the big knife, and the two big knives were compared in front of him, the old sword king became serious, his body was heated to the extreme, and there was really a bit of the taste of martial arts practice, and the new invisible knife mountain was covered on top of the previous one, and Mu Ziyun, who was pressed below, doubled the pressure in an instant.

The fireball was cut into pieces, and the fire qi flowing from the fireball barely blocked the blade outside Mu Ziyun's skin, but it still caused a lot of cracks to appear on Mu Ziyun's body.

Mu Ziyun was very anxious in his heart, the tip of his nose could already feel the cold air emitted by the blade, and in a hurry, he suddenly had an idea, and he raised the hunting bow in his hand with difficulty, attaching a large amount of fire qi to it, and his fingers buckled hard, hissing.... Sou... A rocket pierced through the mountain, dragged its long tail, flew fifty zhang away, and stabbed straight into the body of the old sword king.

The old sword king knew the power of the hunting bow, and immediately raised his double knives to withstand the impact of the rocket, so that the force on Mu Ziyun's body was much smaller, taking this opportunity, Mu Ziyun turned into a fire blade again, first cut out a few paths, and then threw the fire blade to the top of his head, separating the falling knife mountain, and then aimed at the old knife king, and sent out the second and third rockets, the fire gas attached to the rocket was stacked high, and in the end, the two arrows gathered together, roaring and stabbing at the old knife king's chest.

The old sword king stacked the two big knives together, first resisted the first rocket, and then ushered in the next one, the arrows of the three rockets gathered at one point, such as the crisp sound of hitting the metal, and like the noise of thousands of birds screaming together, in the roar of the old knife king, the sky above the dragon valley exploded, countless blades shattered, bounced to the ground, and the Bu Pumen disciples on the ground were pierced into a sieve.

Mu Ziyun found Huzi in time and wrapped the two of them with fire beads, even so, from time to time, a broken blade pierced through the fire qi and cut off the flesh and blood of the two.

This rain of blades fell for a whole hour, and apart from Huzi and Mu Ziyun, there was no living person in the Tattooed Dragon Valley, and there was not even a complete corpse that could be seen.

In the sky above the Dragon Valley, a large area of smoke and dust slowly dispersed, the abdomen of the old knife king was penetrated by silver arrows, and blood was spilling from all over his body, at this moment, the old sword king was not enough to describe it as a killing god, living like a Hades, a pair of eyes were blood-red, the small eyeballs hid an ocean of anger, his teeth were bitten in a few in a vicious way, and the handles of the big knives in both hands were cracked under its huge force, this old guy who had not moved for more than ten years was really angry at this moment.
