"City Lord, are you sure it's a keel?" After Su Mu was shocked, he didn't believe that the dragon bone was such a holy thing, even if it was just a small section, it was enough for the heavens to fight, and it was impossible to appear in such a small place.

If it was a real dragon bone, Danwang City would probably have ceased to exist a long time ago!

"Of course." The city lord bowed his head, and there was a hint of pride in his eyes, such holy relics as dragon bones may not be among your ancient relics, right?

"City Lord, I want a keel." Su Mu spoke decisively, whether it was true or not, take it first.

The city lord's expression was slightly stiff, and he wanted a keel when he opened his mouth, and he had such a big appetite, and he was not afraid of blowing himself up?

"Canglan Danshi, keel ......"

"Does the lord want to break his promise?"

"Of course not, Canglan Danshi misunderstood." The city lord shook his head, since he dared to say that you should pick three things at random, including the dragon bone.

"It's just that the keel is afraid that you won't be able to take it away."

Su Mu raised his eyebrows slightly, but he didn't speak, he wanted to see if he couldn't take it away.

"The dragon bone was obtained by the previous city lord by accident, from the time it was obtained to the time it was put into the treasure house, a lot of divine power has been lost, and now it has been relying on the aura to nourish it, once it is taken away, it will immediately become a waste product!"

The dragon bone, a holy thing, if it is not in a specific environment, if it is not properly protected, it will continue to lose divine power.

But it was not as serious as the city lord said, Su Muhu looked at the city lord suspiciously, and he was now very suspicious of the authenticity of that keel.

Seeing that Su Mu still didn't give up, the city lord simply nodded and raised his hand to invite him to the fifth layer.

When the two of them reached the fifth floor, Su Mu didn't feel anything, and the city lord's face rose with comfort.

In the central position, there is a formation made of spiritual stones, which exudes extremely abundant aura at all times, but Su Mu is still only in the Heavenly Extreme Realm, and he can't perceive or absorb the aura.

"Canglan Danshi, that's the keel."

Su Mu looked up at the sky above the formation, and saw an arm-long white bone wrapped in spiritual energy, glowing with a faint light.

Just looking at it like this, I couldn't see any difference at all, gushing out soul power and reaching for the keel.

"Groan!"

A dragon roar exploded in his mind like thunder, and Su Mu took a step back, his face slightly pale.

"Canglan Danshi, although the divine dragon is dead, it still cannot be offended." Seeing Su Mu like this, the city lord knew that he was using his soul power to test it, and reminded.

"It's just a pseudo-dragon." Su Mu didn't listen to the words of the city lord, and looked at the dragon bone and muttered.

In addition to the ancient congenital dragons, the acquired dragons are mostly cultivated from snakes, snakes turn into pythons, pythons become dragons, and dragons become dragons......

But it can't be called a dragon under the cockroach, at most it can be regarded as a pseudo-dragon, and this keel is the bone on the body of a dragon, which is far from the real keel.

However, even if it is a dragon bone, it is also a rare holy object, if you can refine the essence of the dragon bone, it is a kind of cultivation holy object!

"Canglan Danshi?"

"Try it."

Su Mu's fists were clenched, and a fierce light flashed in his eyes, the dragon bone really can't be taken away, try refining it on the spot!

With his right hand outstretched, a ball of beast fire pulsed in his palm and flew towards the keel.

The city lord was still wondering what Su Mu was in a daze, and when he saw the beast fire flying over, his color immediately changed.

"Canglan Danshi, what are you going to do?"

"Boom!"

As soon as the words fell, the beast fire instantly expanded, enveloping the keel!

"Stop!"

Seeing Su Mu's reckless movements, the city lord jumped up in shock and hurriedly stopped him.

"What the hell do you want to do?"

"Refining the keel."

What? The city lord was stunned for a moment, and then he was angry and whimsical!

"It's a waste to keep the keel here, since you can't take it away, refining is the best."

Listening to Su Mu's words, the city lord shook his head, how could he not understand this truth, but the keel has been placed here for so long, what has he not tried, you can refine the keel with a little doll? Pipe dream!

"Canglan Dan Master, this method has already been tried by the Dan King, and several Great Dan Masters have tried it, and he has also used the beast fire for more than a thousand years, and he has not been able to refine the dragon bone!"

A thousand years of beast fire can't do it, can it be that your eight-hundred-year-old beast fire can? It would only be a waste of those spirit stones he laid out!

"Huh?" After speaking, the city lord was stunned for a moment, looking at the beast fire, his brows gradually wrinkled, and he felt more and more that something was wrong.

"How can you ...... beast fire?"

"No, didn't you get the eight-hundred-year-old beast fire in the Danwang Temple? How can it be stronger than a thousand years? ”

City Lord Huo Ran looked back at Su Mu and said incredulously, how did the beast fire become like this?

Looking at the year, it is true that it is still 800 years, but looking at the energy, it is more than 1,000 years!

Uncanny!

"The beast fire is indeed that eight hundred years old, but when it is fused with the original beast fire in my body, it becomes even stronger."

Looking at Su Mu's indifferent appearance, the city lord was stunned when he heard it!

Can the beast fire still be fused?

Inability to fuse is the golden rule of the alchemy world!

"Canglan Danshi, you, how did you do it?" After thinking about it for a long time, the city lord still couldn't understand it, and asked with difficulty.

Su Mu didn't explain, and concentrated on refining the dragon bone.

"It's a bit hard."

The dragon bone did not change in the slightest in the beast fire, but only burned the surrounding aura in vain.

The city lord came back to his senses and couldn't help but shake his head as he looked at the dragon bone that had not changed in the flames.

"Canglan Dan Master, I have already said it, even if the Great Dan Master comes, it is useless, even if the power of your beast fire has passed a thousand years, it can ......"

"Woohoo ......"

"Boom!"

The clothes on Su Mu's body were gradually burned, and with the black ash fluttering, every inch of skin revealed a scorching flame!

Seeing Su Mu turn into a burning man, the city lord was so shocked that the rest of the words were stuck in his throat, and he looked at this scene dumbfounded!

"Really, it's really a five-element physique!"

That old guy from King Dan really didn't joke with him, Canglan is really the Five Elements Separation Fire Physique!

The Five Elements Physique is definitely among the best among all the innate physiques, and in addition to being shocked, the city lord also has more and more envy.

Who wouldn't want to have such a strong innate physique?

"Boom!"

The flames turned into a long dragon and rushed towards the dragon bone, replenishing the explosive energy for the beast fire!

The dragon bones finally began to change.

But, it's not enough!

"Wind Trick!"

The fire borrows the wind, and the wind veins run wildly, further raising the fire veins!

The city lord's face had begun to sweat, and now the entire fifth layer had turned into a furnace!

Looking at the dragon bones that had turned red in the flames, the city lord wiped his sweat and began to get nervous.

"Can it be refined?"

If you can really refine the dragon bone, even if all those spirit stones are invalidated, it is worth it!

"City Lord, Yuan Core!"

Su Mu's face was difficult, the dragon bone was not so easy to refine, and it was very difficult for him to use the two dark veins, and he had to be supported by the yuan core.

Meta-core? The city lord was stunned, and then hurriedly took out the yuan core and handed it to Su Mu.

"Smack."

In just a few moments, a meta-core will be invalidated.

The city lord glanced at the Yuan Core that had been thrown away, and his pupils shrank fiercely, what a terrifying cultivation speed it would take to absorb a Yuan Core so quickly!

"King Dan, that old thing, everything he said is true!"

Canglan is not only an alchemy demon, but also a cultivation demon!

Whether it is alchemy or cultivation, it is overwhelming, and it is rare to meet opponents!
