Blocking Yaochen's retreat, Qin Chen only gave him the two most clear and direct options.

Seeing that he agreed, Qin Chen smiled faintly: "In this case, summon the bone spirit cold fire, and I will refine it, so that I can also help you kill that Han Feng." ”

Humming noncommittally, Yaochen first hesitated slightly for two seconds, then shook his head, and finally sighed silently, spreading out his illusory palm, on which a cluster of the purest forest white flames could be seen, and this was the real bone spirit cold fire, the existence of the eleventh on the different fire list.

The bone spirit is cold and cold, the flame is cold, it is a strange flame that combines extreme cold and extreme heat, according to legend, only every hundred years, when the sun and the moon alternate, can you meet this fire in the land of extreme cold and extreme yin, which is extremely rare.

"How are you going to refine?" Yaochen said.

Qin Chen didn't answer at first, he stepped forward to take a look, and after groping for a while, his eyes narrowed, and he said in a deep voice: "This bone spirit cold fire was indeed refined by you with medicine dust, but the degree of refining is not the kind of state that does not distinguish between each other. I can reverse refine this Cluster of Bone Spirit Cold Fire of yours, and this process requires your cooperation. And you have to know that after this time, your current soul power will be consumed by at least half, which is at least! ”

"Hmm." Yaochen nodded heavily.

Seeing that Yao Chen had no doubts and was ready, Qin Chen did not procrastinate, looking at the cold fire of the bone spirit that was close at hand, he slowly stretched out his hands, the golden extreme fire covered his hands, and when he came into contact with the cold fire of the bone spirit, the two flames seemed to be the same as water and fire, and the flames of two different colors instantly entwined and clashed...

Controlling the extreme fire, Qin Chen frantically mobilized his spiritual power, blessed the flames, and devoured the cold fire of the bone spirit.

On the other hand, Yao Chen also kept his promise, he could clearly feel that the bone spirit cold fire he had worked so hard to find was getting out of control little by little, but he didn't resist, but cooperated with Qin Chen.

The bone spirit cold fire forest white flame is sheng, even without the support of medicine dust, the different fire has a spirit, and it is instinctively resisting when it is devoured, and Qin Chen's extreme fire is inferior to the bone spirit cold fire, so the speed of anti-refining is extremely slow, but it is also going on little by little.

The Extreme Fire is inferior to the Bone Spirit Cold Fire, not that the Extreme Fire is inferior to the Bone Spirit Cold Fire.

It must be known that the Extreme Fire was taken from the Three-Eyed Golden Lion in the Douluo Continent, the Imperial Rui Beast, and theoretically speaking, the Extreme Fire was not much inferior to the Bone Spirit Cold Fire. As for the main reason why the current extreme fire is no match for the cold fire of the bone spirit, it is still because when Qin Chen killed the Three-Eyed Golden Lion at the beginning, the Three-Eyed Golden Lion was just a thousand-year-old soul beast, and it was just a nascent stage that had not yet fully developed...

Therefore, there is still a lot of room for progress in the Extreme Fire, as long as Qin Chen's cultivation makes a breakthrough, his Extreme Fire will also grow little by little.

And right now, seeing that there is progress in refining, even if this progress is very slow, Qin Chen is also happy, because in this way, it only needs to be slowly reversed, but it will take some time, and it will not hurt.

Raging!

In the cave, hot and cold alternately, sometimes the sky is cold and the ground is frozen and the vines are frosty, and sometimes the red sun is scorching like a volcano that is about to erupt flames, and the anti-refining is continuing.

And under such persistence, it took nearly a week before and after, and Qin Chen had not yet refined the Bone Spirit Cold Fire, but he completely took out the Bone Spirit Cold Fire from Yao Chen's body, making it a short-lived ownerless fire.

In this week's time, Yaochen almost lost half of his life, at this time, his soul was empty, he glanced at the cold fire of the bone spirit burning in the air with emotion, and then turned his eyes sideways, he said to Qin Chen: "Now that the thing has been given to you, I am waiting for your good news." ”

After speaking, Yao Chen slipped back to the quaint ring worn on Qin Chen's left index finger to recuperate his soul.

Qin Chen was the only one left in the cave, looking at the cold fire of the bone spirit in front of him, since it became an ownerless fire just now, the fury of the cold fire of the bone spirit was completely displayed. I saw that its fire increased suddenly, and its power was no longer suppressed, and the dark white flames roared and incinerated the surrounding space into nothingness, and the stone walls on the side were also affected by it, evaporating at a speed visible to the naked eye, and the mountain peaks slowly collapsed...

"Gotta devour!"

The white flames rushed to his face, this strange cold Qin Chen couldn't stand it, took a deep breath, and continued to control the extreme fire to refine and devour the bone spirit cold fire.

While dealing with the cold fire of the bone spirit, Qin Chen took out a wisp of vigilant glance around, always on guard against demonic beasts, or those mercenaries who happened to pass by?

The cold fire of the bone spirit was located halfway up the mountain, even if it was in the power of refining its flame, it was still released, and the top of the mountain was crumbling under its influence, as if it would collapse at any time, and in place, Qin Chen's heart moved, and he controlled the power of the flame to incinerate below where he was...

In this way, the time for refining and devouring the cold fire of the bone spirit passed day by day, and after two days in a blink of an eye, Qin Chen had already burned through the green mountain, not only that, but he also came to the underground, where no one could snoop on, refining and devouring with peace of mind, and in this way, nearly a week had passed.

On this day, Qin Chen suddenly opened his eyes, and at this moment, although the flames around him were burning, the flames were all golden in color, this was the ultimate fire!

Perceiving his own flames, Qin Chen found that compared to before, the power of today's extreme fire had increased significantly, nodding, he withdrew most of the flames, leaving only a cluster in the palm of his hand, and as soon as his mind moved, the original golden flame changed immediately.

The golden flame gradually turned into a red with enchanting power, then into a blood-red fire with a little black in it, and then the color of the flame changed again, taking on a white shape, and a cold and eerie aura enveloped the place.

Bone Spirit Cold Fire!

"The characteristics have been perfectly preserved, and compared to the previous cluster of bone spirit cold fire, the power of the current bone spirit cold fire has also been greatly improved, not bad!"

Qin Chen's eyes flashed with satisfaction, now that he had just come to the Douqi Continent for less than a month, he had successfully obtained a strange fire, he was a little hot in his heart, thinking about the remaining strange fires, if they were swallowed one by one, how strong would they be?

Call.

With a long exhale, Qin Chen withdrew the cold fire of the bone spirit in his hand, looked up at the ground above that was nearly a thousand meters high, and jumped his body and quickly ran upward. Ten seconds later, he came to the ground to tidy up, then walked out of this demonic beast forest, followed the ancient path, and finally entered the city of Utan not far away.

At noon, the sky was bright and bright, returning to Utan City, Qin Chen's purpose was very simple, since he had already obtained the bone spirit cold fire on Yaochen's body, then the next step was to figure out how the level system of the Douqi Continent corresponded to the cultivation of immortals? Also, he didn't plan to buy a map in the city and plan his plan...
