"Well, the first-line Heavenly Canyon has been designed by the masters in the Demon Domain with three barriers, from the inside, the middle, and the outside, and the defense has gradually increased." Nan Chaosi nodded.

Tang Feng glanced at a pair of blazing dragon eyes, which was only more than ten zhang away, and revealed an inexplicable murderous aura. It seems that what the four Southern Dynasties said is true, because from the offensive and defensive point of view, if you attack the Heart Refining Domain from the periphery, then the outermost defense should be the strongest.

Nan Chaosi said leisurely: "This line of Heavenly Canyon, there is another point, if it is attacked from the inside, then from the inside to the outside, the defense will gradually increase." If you attack from the outside, then from the outside in, the defense gradually increases. ”

Originally, Tang Feng thought that the speculation was correct, but when he heard Nan Chaosi say this, he was stunned for a while, but soon, he said resolutely: "Whether it is strong inside or outside, we have no choice." The only way is to kill it!"

"Yes, we don't have a second way to go!" Nan Chaosi flicked his long sleeves, and the long flute clenched in his hand, "I suddenly thought of a way, maybe I can get twice the result with half the effort." ”

"Uh, what's the method?" Tang Feng asked.

"Joint operations!" Nan Chaosi said thoughtfully.

Chu Yu sneered disdainfully, and glanced at Nan Chaosi, "If you have any bad ideas, you just hurry up and say, don't mother-in-law!"

"Hehe, don't you claim to be smart and unbeatable in the world?" Nan Chaosi lost no time in "taunting" Chu Yu.

"You ......" Chu Yu was speechless for a while, and he didn't know what to say, so he only glared at Nan Chaosi viciously.

Nan Chaosi seemed to have cultivated a natural cheekiness, but he didn't care, and then said: "The four of us, if we say that the most lethal power is Tang Ye and his chivalrous sword. However, in such a natural terrain, for Chu Yu, who is good at sound waves, I mainly use the sound of the flute, and the great protector is mainly based on the 'lion's roar gong', it can be said that the three of us rely on sound waves. ”

"Therefore, in such a narrow canyon, the sound wave can be strengthened by several times, so we will join forces to use the sound wave to stimulate Tang Ye's sword qi, and it is conceivable that the lethality will be more than ten times stronger. He rolled his eyes full of wisdom, and commanded.

Tang Feng sighed, the sword in the dragon's claws was raised, and he said calmly: "In this case, what are we waiting for, kill it!" After speaking, he had already taken the lead.

Chu Yu, Nan Chaosi, and Chu Long swept up almost at the same time, and swept towards the valley mouth of the First Line Heavenly Canyon.

Before everyone reached the center of the Heavenly Canyon, suddenly, a gust of wind rolled up on the ground, "whoosh", the wind roared, and gradually, it condensed into a cyclone that was enough to block the direction of progress, and it was actually a coiled tornado.

The tornado rolled up all the dust in the Sky Canyon, and the surrounding grass and trees and fallen leaves were all condensed in the tornado that was a hundred times stronger. From a distance, the fierce hurricane hovering can be described as a white dragon that wants to fly into the sky.

However, gradually, the tornado devoured everything, destroyed all the surrounding plants and trees, and collided with Tang Feng and the others.

Tang Feng, Chu Yu and the other four couldn't help but panic for a while, if it was an ordinary object monster, it could still be dealt with, but how could this raging tornado be resisted?

Admittedly, it would not give the four of them room to think, and this tornado rolled towards the four of them as if it had eyes.

Tang Feng calmed down slightly, the dragon claw clenched the hilt of the sword, and the strong current around his body was condensed, and suddenly, the body of more than 100 zhang glowed with flashing golden scales, and the already hideous dragon head face was even more grinning, and he actually swept out the purple and cyan sword of the chivalrous sword without fear.

Chu Yu, Nan Chaosi, and Chu Long saw the situation, and they didn't flinch, Chu Yu first volleyed into the air, and the thirteen-string Luo Yin Qin turned into a strong light, and her jade fingers plucked extremely quickly, "Ding Dong...... Ding Dong ......" The melodious sound of the piano exudes an infinite murderous aura, and the sound waves are everywhere, almost piercing into the tornado at the same time as the sword waved by Tang Feng.

The four generals of the Southern Dynasty placed the long flute horizontally, and a stream of air at the dantian of the sea of qi slowly condensed, and the long flute was played, and the sound of the flute was harmonious, and the sound wave was also long and powerful.

Chu Long took a deep breath and condensed the air flow at the dantian, then opened his mouth and roared to release the most powerful cyclone.

"Boom ......"

The cyclone under the sword gathered three powerful sound waves, colliding with the tornado, and the tornado was actually exploded and gradually dissipated.

However, the tornado has not yet faded, and there are a few piercing sounds, but I didn't expect that in this line of heavenly canyons, there were dazzling lightning strikes, and the lightning that tore through the sky shook Tang Feng and others.

Nan Chaosi sneered: "The masters in the Demon Domain are really powerful, I'm afraid they have all been used, hum, let me do this lightning!"

After finishing speaking, Nan Chaosi jumped up, his hand shook, and with a "bang", it turned out to be a long chain of iron cables shaking out of his sleeve, and he threw it towards the constantly flickering current.

"Snort......" lightning struck the iron chain, and he threw the chain again, firmly into the stone crevice in the canyon of the first line of heaven. Everyone watched as the lightning that fell from the sky slashed into the crack in the stone along the iron chain.

"Bang!"

"Boom ......"

The stone wall was shattered by lightning, and suddenly, another boulder rolled and smashed, and the upper end of the crumbling first-line sky canyon collapsed, and dust and stones fell from the sky one by one, and there was a tendency to bury the four of them.

Tang Feng shouted: "Run!" His body of more than 100 zhang shook and rose into the air, and the purple and cyan light of the sword swept out, condensing into a barrier, protecting Chu Yu, Nan Chaosi, and Chu Long.

Chu Yu, Nan Chaosi, and Chu Long dared to coil over, and in a hurry, they had already jumped up and rushed out towards the First Line of Heavenly Canyon.

Tang Feng's giant tail swept wildly, rolling out a lot of dust and stones, and his body burst out, and he had already arrived at the position of the first line of heaven canyon three or four zhang away from the mouth of the valley.

Nan Chaosi grinned, patted his chest lightly, and glanced back at the gravel of the mound that had been piled up halfway up the mountain in the Heavenly Canyon, "Damn, the second barrier has finally passed, I don't know what the mystery of this last barrier is!"

Tang Feng glanced at the valley mouth at a distance of only three or four zhang, and couldn't help but say with a little urgency: "The master doesn't believe that he has a doomed entrance." Before the words fell, he jumped up, hovering his body more than a hundred feet and looking at the valley mouth crashing.

Nan Chaosi just wanted to stop it, but it was too late, staring at the big eyes, looking at Tang Feng's long body as if he had broken out, but he was bounced back by something. The entire body of more than 100 zhang was bounced back alive by the seemingly mysterious Taniguchi.

Chu Yu and Nan Chaosi couldn't help but be shocked, glanced at Taniguchi in disbelief, and then, they all took a few steps back and stepped forward to check Tang Feng's injuries.

"Tang Feng, are you okay?" Chu Yu asked with concern as he looked at Tang Feng, who was curled up in a ball, and the golden scales were dim.

"Wow!" Tang Fenglong's mouth opened and a mouthful of blood gushed out, and the dragon's eyes lowered a little dejectedly, and he breathed slightly before he said slowly, "It's okay, it's such a strong airflow!"

Nan Chaosi condensed his eyebrows and said abruptly: "Tang Ye, don't be impulsive, don't underestimate the distance of three or four zhang, in fact, it is full of dangers, and it is not simple." ”

Tang Feng said "um", and said silently: "The valley mouth that seems to have no obstacles, but it is an extremely strong barrier, just now I went up, I actually felt that my body was weightless, as if I was falling into the darkness of the endless void, the bottomless deep valley. However, suddenly, someone smashed a huge hammer at my head from the shadows......"

Nan Chao Sichang sighed, and also frowned, expressing his puzzlement.

"This barrier is called the 'Demon Seal', and it is a barrier formed by the death of the masters in the Demon Domain for thousands of years. Even if you have all the skills, it is difficult to break through this threshold. Because this 'magic seal' is strong when it is strong, and weak when it is weak, it is even more difficult for us to cross this barrier!" Chu Long frowned, strode over, and said in a deep voice.

Nan Chaosi muttered in his mouth: "Demon Seal? Could it be the legendary 'Demon Seal' that guards the territory of the Demon Domain?"

"Exactly, for thousands of years, the righteous path has attacked the Demon Domain, and no matter what magical power there is, it will not be able to break this 'Demon Seal', so the Demon Domain can survive for eternity. Chu Long elaborated. (To be continued.) )
