It is rumored that there are thirty-six Heavenly Thunder Balls in the cultivation world, but it was a powerful man who personally sealed and refined the power of Heavenly Thunder into thirty-six Heavenly Thunder Balls when he experienced the Thunder Tribulation. It is said that these thunderballs contain the energy to destroy the heavens and the earth, and no matter who is caught up in the thunderballs, there is only one way to fall.

Among them, there was also an incident recognized by the cultivation world, more than a thousand years ago, there was a medium-sized sect in the cultivation world called the Purple Sword Sect that was broken into the mountain gate overnight by his opponent, the Water Moon Sect. Seeing that the entire sect was about to be completely annihilated, in the end, the master of the Purple Sword Sect led all the disciples to hide at the altar of the sect.

When the monks of the Water Moon Sect chased after the altar, they were about to destroy the Purple Sword Gate, when suddenly a huge explosion broke out from the altar of the Purple Sword Gate, and then all the monks in the center of the altar were martyred.

Later, according to the monk who escaped from it, the thing that exploded was the thunderball.

The obese monk among the ten seemed to have studied the Celestial Thunderball very well, and told what he knew.

"You know better, this Heavenly Thunder Ball has already been consumed a lot after countless months since it appeared in the world, and the remaining ten are collected by my Heavenly Sword Sect. In fact, its power is not as great as rumored, and it takes a certain amount of time to activate the Celestial Thunder Ball, so it is not practical in monk battles. Mo Wuji explained.

"The Heavenly Sword Sect actually has such a sharp killing weapon, it really deserves to be one of the six major sects. Yu Feifan sighed in his heart.

"Then each of you will be given a scroll, and I'll tell you how to drive it. When the time comes, you can find the eye of the formation, and you just need to activate the Sky Thunder Ball. ”

"Where is the eye of the Demon Suppression City Array?" Yu Feifan couldn't help but ask.

"In fact, the destruction ban has long been laid in the underground of the Demon City, and it is only because the demon clan's attack speed is too fast that the true law cannot be activated. ”

"I see, now that the Demon City has been completely occupied by the demons, even if we can hide the identity of the demons, I'm afraid we won't be able to pass through the layers of levels. ”

"Don't worry, someone will take us into the city. Mo Wuxian said confidently, "And this destruction of the Demon City is not only from our Heavenly Sword Sect, but also from the Bodhi Sect, and there are also monks from the Bodhi Sect who infiltrate at the same time as us." ”

"Bodhi Gate?" Yu Feifan's expression moved, and a flash of inspiration flashed in his mind, he seemed to know the female cultivator on the street who snatched the magic ring from him.

"I've already told you about it, and I'll let you know at the end that, as the boss said, if this mission fails, none of you will be able to return alive. I'm not going to show mercy. Mo Wuxian said with a murderous aura at the end, which made the last bit of thought in the hearts of several people also be dispelled.

Mo Wuxian didn't restrict the movement of a few people, perhaps he knew that these people couldn't escape his control. Life and death were in his thoughts.

Yu Feifan was not ready to rest twenty and quietly left his own residence in the inn, although he did not fly with all his strength, his speed was not slow in the night sky.

It was only an hour before and after, and Yu Feifan flew to the mountain range closest to Fu Demon City, the Feiyun Mountain Range. Standing on the empty mountain peak, you can almost see the lights of Fu Demon City without mobilizing your spiritual power, and you can even hear the noise of the demons in the city.

He did not rush into the city, but found a very remote valley in the Fuyun Mountains and used the dripping sword to open a simple cave in it.

"Come out!" Yu Feifan muttered to himself, and then a yellow light flew out of his body, and several runes flew in the yellow light, and after a burst of light, he turned into a boy with red lips and white teeth.

"Xiao Yuanzi has seen the master!"

"You're welcome, is it true that you can teleport over long distances?"

"My body already has a void teleportation ban, but I am now in the state of the primordial spirit and can't fly, but if I use some magic circle assistance, I can transfer a short distance. Xiao Yuanzi said confidently.

Yu Feifan didn't hesitate any longer, his spiritual sense moved, and dozens of materials flew out of the storage bag, all of which he had purchased before leaving the sect, since he knew that this mission was very dangerous, Yu Feifan couldn't help but make some preparations, and put his fate in the hands of unpredictable things, he still couldn't do it.

The teleportation array is a high-level magic circle in the cultivation world, especially the long-distance teleportation array, most of which are sect secret techniques, and only strong sect financial resources can be built. Moreover, immature teleportation circles are very dangerous, some simple teleportation circles are extremely risky, and the teleported monks are easily crushed by the power of time and space.

Although there are only dozens of materials, they are all high-grade materials, which almost emptied all of Yu Feifan's net worth. In particular, the Starry Sky Stone is a necessary material for the teleportation circle.

According to Xiao Yuanzi's guidance, Yu Feifan portrayed the magic circle little by little, although the process was a little slow, but fortunately, he had already deduced it countless times in his heart, and finally succeeded.

In fact, this is not a successful teleportation array, because the most important thing about this kind of circle arranged by Yu Feifan is that it needs the brand of Xiao Yuanzi.

"If the master wants to teleport here, it is not enough to have this magic circle, I can't directly sense this magic circle now, and I still need to arrange another magic circle in the teleportation place. Moreover, this simple teleportation circle is extremely risky, and the load on the monk is very heavy, and it seems that it cannot be teleported without absolutely. Xiao Yuanzi reminded.

|“ Got it!" Yu Feifan's bright eyes flashed, and the depths of his eyes revealed perseverance and sharpness. He also thought about escaping, but chose to stay. If he had to find a reason, he was really a little reluctant to leave the Heavenly Sword Sect, after all, it was still a place where he could stay. Let's talk about the war between man and demon, although Yu Feifan is nothing, he should do his part.

In addition, if he wants to re-cultivate the 'Xuanwu True Demon Skill', he must use demonic energy, so he can't avoid having to come into contact with the people of the demon race, and only real life and death can make the perception of cultivation go further.

That being said, it's not that easy to sneak into Fumo City alone. Yu Feifan secretly unlocked the 'Five Yin Seal' in his body, and the huge demonic qi instantly spread all over the meridians. After taking out the red mask that Xuan Ku gave him from his body, there was no demon clan who could see through his identity.

As soon as his figure moved, Yu Feifan walked directly towards Fu Demon City, and at this moment, a demon cloud fell from above, and seven or eight demon people dispersed and appeared, and in the middle of them actually gathered these dozen or so human monks. It's just that these people are bound by chains, with magic talismans on their foreheads, and their expressions are sluggish.

Several people walked to the gate of Fu Demon City and were blocked, it seems that there is a curfew.

Yu Feifan hid aside, and after only half an hour, there were several groups of demons like the previous one who were detaining the Terran monks to enter. Yu Feifan's mind moved, and his body disappeared in an instant, and soon he found three blue-cheeked demons not far from Fu Demon City, and behind them were also escorted two women, three men, and five human monks.

"With these demon slaves, we can get a lot of magic stones. One of the tall demons laughed maniacally.

"Yes!" one of the remaining two demons chimed in, his tone equally full of excitement. These demons didn't have any special awareness of fighting at first, and just listened to the decisions of the higher-ups. But after tasting the sweetness, he can no longer suppress the killing in his heart, and now even if the upper level demons want to end the war, I'm afraid they have to consider the opinions of these people
