Without waiting for the demon dust wind to ask again, the Seven Demon Lord's expression suddenly turned cold, and he stared at him with a cold gaze and said, "What I said just now, I hope you can rot in your stomach." ”

Demon Dust Feng's heart moved, as if he had grasped the handle of the Seven Demon Lords, and met the gaze of the Seven Demon Lords with a calm face: "Why?"

"You seem to have forgotten where you are?"

The Seven Demon Lord's narrowed eyes flashed with a hint of cold edge: "Don't try to provoke me, although I plan to refine your divine soul into a mountain and river ding instrument spirit, but it is not necessary for you, if you annoy me, you don't expect to be able to scatter your soul." ”

Thinking of the methods of the Seven Demon Lords, Demon Dust Wind couldn't help but shudder, and said, "I was just joking with you just now, you know, my mouth has always been very strong, otherwise Duan Chen wouldn't have known about my existence until now." ”

"Hehe, don't worry, he'll soon know of your existence. The Seven Demon Monarchs smiled and said, and before the Demon Dust Wind could react, a wisp of Duan Chen's divine sense was led by the Seven Demon Monarchs into the Mountains and Rivers Ding and appeared on the altar.

Duan Chen, who was suddenly summoned into the Mountains and Rivers by the Seven Demon Lords, looked confused, but when he saw the spirit of the demon dust, he couldn't help but have a look of astonishment on his face.

In the past, in order to cultivate with the help of the illusion space in the mountains and rivers, he often traveled to it, so he naturally had already noticed this altar built under the Divine Tomb Island and the broken ball of light suspended in the center of the altar.

Of course, he had also asked the Seven Demon Lords about the purpose of the altar, but the Seven Demon Lords always said that the time had not yet come.

Now it seems that the time has come.

He was suddenly a little curious, why the Seven Demon Lords left behind the spirit of the Demon Dust Wind.

The Seven Dead Demon Monarch seemed to have guessed what Duan Chen was thinking, and slowly explained, "Do you remember that I told you before that I was seriously injured back then, and in order to avoid the collapse of my soul, I had to choose to merge with the Mountains and Rivers Ding and become the Spirit of the Mountains and Rivers Ding in order to survive to this day?"

"Yes. Duan Chen nodded again and again, but a wisp of different color flashed in his eyes.

In the past, when he was a Qi refining cultivator, even if he suddenly heard that the Seven Demon Lords had been severely injured, (ròu) (shēn) had been destroyed, and his soul had been damaged, he didn't think much about it.

But after coming into contact with the Seven Dead Demon Lords over the years, Duan Chen felt more and more that the previous strength of the Seven Dead Demon Lords was absolutely unfathomable, and it was very likely that they had reached the realm of merger and even Mahayana.

What kind of person can inflict heavy damage on the Seven Demon Lords and injure him, and what did the Seven Demon Lords do before?

These questions were entrenched in Duan Chen's heart, and they had never been answered, after all, if the Seven Demon Lords didn't take the initiative to explain, even if Duan Chen asked, it would be in vain.

Just when Duan Chen was thinking like this in his heart, the Seven Dead Demon Monarch said to himself: "Because of the choice made back then, my divine soul has now completely merged with the mountains and rivers ding, unless there is another divine soul to replace me, I can't get rid of the shackles of the mountains and rivers at all." ”

"So you chose the Demon Dust Wind?" Duan Chen was not stupid, as soon as the Seven Demon Monarchs explained, he immediately understood the cause and effect of the matter (qíng).

"Well, it takes a long time to cultivate a new machine spirit, and the means are cumbersome, and under the conditions at that time, I can only choose him. The Seven Demon Lord muttered, "But there is one more thing you need to do before he becomes a new machine spirit. ”

"What's the matter?" Duan Chen asked curiously, followed by his reaction, and then asked: "

There won't be any danger, right?"

"There is no danger. The Seven Mortal Demon Monarch smiled gently: "This matter is only good for you, there is no harm, haven't you always wanted to refine the Shanhe Ding? To refine the Cave Heaven Spirit Treasure of the level of the Shanhe Ding, there is a problem that must not be avoided, and that is to accept the Instrument Spirit." ”

After a slight pause, he continued: "If the original Shanhe Ding's instrument spirit is still there, don't say that it is you now, even if you break through to the god transformation stage in the future, it will be very difficult to tame the Shanhe Ding's instrument spirit, but now, there is a great opportunity in front of you." ”

As he spoke, the Seven Demon Lords rolled their eyes and looked at the Demon Dust Wind Divine Soul with a smile.

This made Demon Chenfeng shudder in his heart, but now that people are swordsmen and I am fish (ròu), he can't resist at all, so he has to say seriously: "What do you need me to do?"

"You just have to be honest and happy. The Seven Demon Lord's eyes narrowed slightly, "Don't try to do anything, otherwise you should know the consequences." ”

After speaking, he turned his head to look at Duan Chen and asked, "Do you remember how to cast the ghost soul mark that was subdued before?"

"Yes. Duan Chen nodded, but in his heart he vaguely guessed the plan of the Seven Demon Lords.

"Let's get started. The Seven Demon Lords said lightly: "You first subdue the spirit of the demon dust wind, and when he becomes the instrument spirit of the mountains and rivers in the future, he will naturally be tamed by you, which is also one of the few methods that can refine the Cave Heaven Spirit Treasure below the god transformation stage." ”

And so it was. A flash of surprise flashed in Duan Chen's eyes, but his divine consciousness quickly condensed a divine sense imprint in a single move, slowly implanting it into the depths of the demonic wind's divine soul.

Because of the experience of subduing the ghosts, coupled with the fact that the demon dust wind did not resist, Duan Chen smoothly imprinted his divine sense imprint in the depths of the demon dust wind's divine soul.

From now on, as long as the demon dust wind had any intention of rebellion, Duan Chen's mind could make it disappear in an instant.

"The hosts. "Demon dust wind is also quite knowledgeable, immediately bowing (shēn) salute, his movements are calm, and his expression (qíng) is serious, which can make people feel his sincerity.

However, after Duan Chen's training by the Seven Dead Demon Lords, he was no longer the foundation building monk who could only run away in the face of the demon dust and wind, and he didn't eat him at all, he just nodded slightly, and then said to the Seven Dead Demon Lords: "Senior, I'll go out to find the veins of earth and fire first." ”

After speaking, as soon as his consciousness was scattered, his mind took the initiative to withdraw from Shanheding.

The Seven Demon Lords looked at the demon dust wind with a playful expression, and there was a trace of indescribable weirdness in the dark purple demon pupils.

Seeing this, Demon Dust Wind couldn't help but shrink his neck, and said in a low voice: "As we agreed, I didn't reveal anything to him. ”

"It's good that you know. The Demon Pupils of the Seven Demon Lords narrowed slightly, and said coldly: "Even if you really become the instrument spirit of the Mountains and Rivers in the future, I will also have a way to erase your existence, so you'd better not have any other thoughts." ”

"You don't need to threaten me. When the demon dust heard this, he calmed down: "I am a smart person, and smart people never do stupid things." ”

"Really?" the Seven Demon Lords smiled and said, "But smart people sometimes are mistaken by cleverness. ”

Dropping these words, the Seven Dead Demon Lord (shēn) moved and flew straight towards the center of the Divine Tomb Island, and soon disappeared.

……

Being able to see the hope of refining mountains and rivers, Duan Chen's heart (qíng) was very happy at the moment, but he did not forget his purpose

, followed by the ghost ghost (shēn), to the area where the veins of earth and fire they have found.

It didn't take long for the two of them to leave the barren river and find themselves in an undulating desert landscape.

Later, under the leadership of the ghost, Duan Chen went deep into this desert for hundreds of miles, and finally found a desert crack that went straight to the ground.

"Master, the veins of fire are in the deepest part of this desert rift, and I have already gone down to investigate it before, and there is no danger in it. The shēn shape hovered above the desert rift, and Chong Duan Chenyu reported with a respectful face.

"Well, thank you for your hard work, next I will use this vein of earth fire to refine the Tiandu spear, and you will protect the Dharma for me on the periphery. Duan Chen (shēn) floated at the entrance to the desert rift, and said to the ghost with a calm face.

"Yes. ”

The ghost's gaze looked around for a moment, and in an instant, the shēn shape turned into a bloody light, disappeared into the nearby desert, and quickly disappeared.

However, Duan Chen, relying on the spiritual connection between him and the ghost, could sense that he was hiding nearby, and at that moment, he couldn't help but turn into a magic light in his heart, and flew straight to the depths of that desert crack.

A moment later, on the mountain wall next to a lava river located deep in the crack, hundreds of blood light sword qi descended under Duan Chen's (cāo), quickly cutting through the rocks on the mountain wall.

After a few dozen breaths, a simple cave appeared in front of him.

For the sake of caution, Duan Chen first arranged several formations at the entrance of the cave mansion before entering the cave mansion without a face (qíng), and then under the guidance of the Seven Demon Lords, he began to arrange the formations to channel the power of flames contained in the vein of earth fire into the cave mansion.

After doing all this, he had a thought and took out all the five element materials that had been prepared in the storage ring.

Finally, Duan Chen summoned out the Tiandu spear that had been kept in the dantian, and under the traction of his divine sense, he gently floated in front of (shēn).

Glancing at these things with his eyes narrowed slightly, Duan Chen took a deep breath and immediately sat down cross-legged in place.

Although this was the first time he had rerefined his natal magic weapon, with the power of his divine consciousness that was now comparable to that of the early stage of the Infant, coupled with the guidance of the Seven Demon Lords, he naturally had a good idea of this.

Moreover, rerefining the natal magic weapon is not to re-refine a new natal magic weapon, but to use the original natal magic weapon as a tool embryo and integrate many high-level materials into it to achieve the purpose of improving the quality of the natal magic weapon.

As for whether the retrained Tiandu Gun can reach the top-grade magic weapon, it depends on luck.

If you're lucky, maybe with one retraining, you can raise the grade of the Tiandu Spear to the level of a high-grade magic weapon.

Thinking like this in his heart, Duan Chen immediately waved his hand, sacrificed the Purple Immortal Pill Ding, and followed the method in his hand to pinch it, and a blazing (rè) fire wave immediately gushed out from the ground, and under the guidance of the formation, it was injected into the Purple Immortal Pill Ding, causing the temperature inside the entire Danding to soar suddenly.

Duan Chen's eyes flashed, and with a wave of his hand, a magic trick immediately hit the Purple Immortal Pill Ding.

The next moment, I saw a flash of inspiration on the danding, and the dinglid levitated by itself.

Seeing this, Duan Chen immediately rushed to a piece of five-element material next to (shēn), and with a flick of his sleeve robe, the five-element material immediately flew into the Purple Immortal Pill Ding.

Then he no longer paid attention to this thing, and successively put the other five elements materials into the Danding and began to refine them.
