Just when Xiong Lie regrouped his men and horses and was about to approach the Dragon Slayer Alliance to find out the whereabouts of the princess and the black dragon, Zhang Qingfeng had already taken Du Dayan into the dragon's lair.

As for Shangguan Yunhe's frequent return to the so-called transmission of news, it was naturally arranged in advance, in order to buy him time to hunt for treasures.

Originally, after the little black dragon Bai Xue recognized the master, Zhang Qingfeng had lost interest in the so-called dragon's lair treasure.

In his opinion, even if there were mountains of gold and silver hidden in the cave, and they were full of artifacts, they were not as important as a piece of dragon scales of the little black dragon.

But after all, this is the place where the little black dragon is imprisoned.

He is also the owner of the little black dragon, and everything in the dragon's lair is naturally his own, if it is left to outsiders like this, he is really a little reluctant.

Especially the rope that penetrated into the body of the little black dragon was actually harder than the keel, which meant that this was at least a high-grade holy weapon, if it was not taken away, it would be too tyrannical.

Zhang Qingfeng left everyone outside to delay time, and only brought Du Dayan, who could see at night.

After entering the cave a few steps, Du Dayan found a pile of bone fragments on the ground.

"This is the keel of the snow. ”

Zhang Qingfeng took matters into his own hands and picked up all the bone fragments without pulling them, and actually packed two four-grade storage bags.

Dragon bones, versatile and valuable, are the top alchemy materials in the mainland, Zhang Qingfeng naturally collected them not to refine the elixir, everything about the little black dragon, he had to take it away and treasure it, in order to make up for the carelessness and dereliction of duty he had taken care of her for thousands of years.

The cave was deep, with a twist and turn, and the ground beneath your feet was high and low, but you could feel that it was leading deeper underground.

After walking for about two thousand meters, a magnificent underground hall suddenly opened up in front of him, and a magnificent underground hall appeared in Zhang Qingfeng's sight.

This hall is extremely wide, the surrounding lamp walls are brilliant, five white jade totem poles with a diameter of seven or eight meters rise from the ground, supporting the top of the cave a hundred meters high, and the surrounding walls are burning with everlasting lamps made of unknown materials, and the bright lights illuminate the hall as bright as day, even without the guidance of Du Dayan, Zhang Qingfeng can also see clearly.

"Your Highness, quick, look, good, what a big treasure!"

Du Dayan suddenly grabbed Zhang Qingfeng's clothes, pointed to a mountain in the depths of the hall that exuded colorful light, and said that the words of excitement were not good.

Zhang Qingfeng naturally saw the treasure mountain, but his attention was attracted by an inconspicuous dark red rope on the ground.

"Be careful, follow me, don't walk around, and don't touch it, there may be an ambush here. ”

Du Dayan's excited heart was about to jump out of his throat, and he had not even seen a few pieces of kyanite for more than 20 years, and he resisted the urge to pounce on the entire treasure mountain, and nodded fiercely.

Zhang Qingfeng walked to the side of the string, bent down to pick it up, and his hand was delicate and silky, as light as nothing, as if grasping the finest silk in the world, indescribably comfortable.

"Your Highness, this, this is the rope that ties the dragon girl?" Du Dayan quickly remembered the rope he had seen before.

"That's it. ”

"Wow, what is this made of? Even the dragon girl can lock it!" Du Dayan stared in surprise at those small eyes that were half smaller than ordinary people.

"There are not many things on the continent that can lock the Divine Dragon, and the spider silk of the Flower Kiss Demon Spider is one of them, and this red rope is woven from the silk of the Demon Spider. ”

"Flower Kiss Demon Spider ......" Du Dayan muttered, looking dazed, this name is very unfamiliar, I have never heard of it.

Zhang Qingfeng held the head of the rope and shook it gently, and the red rope shook like a wave, spreading all the way to a stone pillar fifty meters away.

"The spider silk of the flower-kissed demon spider is not only tough, but the biggest feature is that it is elastic, this fifty-meter spider silk can be stretched fifty times! It is one of the most elastic materials in the upper continent, if it is auctioned, one meter can sell hundreds or even tens of millions of amethyst stones, and the person who can use it to trap the little black dragon is by no means an ordinary martial artist. ”

"Amethyst, or tens of millions?" Du was stunned, he really didn't care about how much wealth it was.

Zhang Qingfeng ignored the stunned Du Dayan, wrapped the spider silk in his hand, and walked as he went, until he stopped under the stone pillar.

"No wonder you can't break free, it's actually the Twelve Weeks Heavenly God Evil Array. ”

Seeing the intricate runes under his feet and the spider silk buried deep in the stone pillar, Zhang Qingfeng finally understood why the little black dragon couldn't break free, and a powerful magic circle was actually laid in the pillar, no wonder, if it didn't use the magic circle, no matter how hard the pillar was, it couldn't withstand the collision of the divine dragon.

"You take two steps back, I'll break the formation first. ”

Zhang Qingfeng waved his hand to signal Du Dayan, who had caught up, to step back, opened the Qiankun bag, and took out a broken sword that Du Dayan had never seen before.

"Qianli, do you believe in your fate?" Zhang Qingfeng suddenly asked.

Du Dayan was stunned, and he didn't understand why Zhang Qingfeng suddenly asked this, and said with a smile: "I used to believe it, but after I met His Highness, I didn't believe it." ”

Zhang Qingfeng obviously didn't care about Du Dayan's answer, looked at the chaotic remnant sword in his hand and said, "Do you know where this sword came from?"

Du shook his head: "No, I don't know." ”

"This is the first reward I got when I participated in the hunt in Zhou Yuan, don't look at him as just a broken sword, but he is the nemesis of all magic circles in the world, if I don't get it, this red rope made of thousands of spider silks can only stay in the cave. ”

Zhang Qingfeng's preface did not match the question, and Du Dayan, who listened to the question, was confused, thinking about the treasure mountain not far away, and did not ask about the origin of the Chaos Divine Sword, and said: "Then Your Highness, hurry up and break the formation, this underground palace is so big, I'm afraid it will take a lot of time to finish, don't let the rabbits wait for them." ”

Hua Mantian, the strongest person in the Western Regions of the Dayan Continent thousands of years ago, is known as the nemesis of the formation mage, his chaotic remnant sword specializes in breaking the world's top magic array, although Zhang Qingfeng's attainments in arranging the formation are far less than Hua Mantian, but the ability to break the formation is not much worse than him.

The Twelve Weeks Heavenly God Demon Great Array is one of the eight great heaven-level Great Arrays in the famous cultivation world thousands of years ago, and what is in front of him is only a reduced version of the transformation, for the little black dragon who has not yet reached adulthood, it may be unbreakable, but in front of Zhang Qingfeng's Chaos Divine Sword, it becomes vulnerable.

I saw Zhang Qingfeng insert the remnant sword into the stone pillar, and as the spiritual energy in the body poured into the sword body, the runes on the sword body were quickly lit up, only to hear a burst of clicking sound from the stone pillar, and the half of the rope buried in the pillar suddenly popped out, and the magic circle on the stone pillar was broken.

"Let's go. ”

Putting away the spider silk red rope and the Chaos God Sword, Zhang Qingfeng greeted with a calm face, Du Dayan was very unfamiliar with the Divine Evil Array and the Chaos God Sword, and he didn't ask too much, and it wasn't until many years later that he understood what kind of feat Zhang Qingfeng had accomplished in less than a cup of tea just now.

"This is the treasure mountain you dream of. ”

It wasn't until he walked to the side of the jeweled mountain that Zhang Qingfeng stopped.
