In the next few days, Dugu Jian has been preparing for his cultivation.

The first is the "Eight Fierce Xuanhuo Array", Dugu Jian modified this formation according to his own needs, abandoning the performance of the flexible attack of the magic circle, narrowing the attack range of the magic circle, thereby strengthening its upper temperature limit.

The second is the incense valley's exercise "Incense Jade Book", Dugu Jian probably practiced after reading it, and had some in-depth understanding of the fire system Dao method, and made some modifications to the "Eight Fierce Xuanhuo Array".

In the end, Dugu Jian opened up a new method of refining the body according to the characteristics of his immortal body:

Xuanhuo Alchemy.

When one's body is burned by Xuanhuo, it will run automatically, and every time the body is burned by Xuanhuo and recovers, the strength of the physical body will increase to a certain extent.

In this way, Dugu Sword can refine its body at the same time in the process of transforming internal force and spiritual power, which greatly saves the time of cultivation.

Of course, this is just a purely theoretical, rough method of refining the body, and there will be many problems in the process of refining the body, but in view of the fact that you are immortal, there is no need to be so cautious, and you can slowly improve it in practice.

Ten days later.

A woman in a long white dress walked into the Xuanhuo Altar and brought the last thing that Dugu Sword's cultivation lacked.

"Xiaobai sees the ancient gods."

The woman knelt in front of Dugu Jian, her snow-white hands raised, and the palm of her hand was a palm-sized object like a jade pendant.

"This is what you look like?"

Dugu Jian took the Xuanhuo Jian, looked at it a few times, and then returned his gaze to Xiao Bai, staying on her exaggerated curves for a long time.

"Yes." Xiaobai's voice is clear and smart, as pleasant as a wind chime.

Maybe it's because she's a nine-tailed sky fox, and in her, there's a charm that emanates from her bones.

Dugu Jian has read countless beauties, and he has never seen such a charming woman.

"You look good like this, in the future, you should become a fox."

“？” Xiao Bai's bright eyes were full of incomprehension.

"Can you become a palm-sized fox?"

"Yes."

In Xiao Bai's light voice, a stream of aura surrounded her body, and the snow-white long skirt fell to the ground, and then, a palm-sized snow-white nine-tailed fox jumped out of the skirt.

At Dugu Jian's signal, the palm-sized nine-tailed fox jumped onto Dugu Jian's shoulder.

"Yes, it's like a pet."

Dugu Jian sighed in his heart, a little nostalgic for his comrades-in-arms, if his comrades-in-arms were here, how could he make Xiaobai become a fox.

As part of the remnants of the ancient gods, the comrades-in-arms were also coaxed by everyone, but the reason for the scramble was not a strong force.

The disciples of the famous and decent family are upright on the surface, but they can't get rid of worldly desires inside, and the two body parts that fell on Qingyunmen are all hidden by the disciples under the sect.

If it weren't for his comrades-in-arms who were doing well in Xiaozhufeng, Dugu Jian would have gone to find it a long time ago.

However, this matter can't be delayed, and when he finishes the matter at hand, he must go to Qingyunmen Xiaozhufeng to pick up his comrades.

Let's get down to business. ’

Dugu Jian's attention returned to Xuanhuo Jian.

Xuanhuo Jian is the most rigid and yang thing between heaven and earth, it is the essence of ten thousand fires, the quality is far beyond the Nine Heavens Divine Soldiers, looking at the entire Zhuxian world, there are few treasures that can be compared.

It is precisely because of this that if you take Xuanhuo Jian as the core and arrange the Eight Fierce Xuanhuo Array, its power will be greatly increased, and the five-fold increase that Yun Yilan said is still too conservative, if it is used well, the increase will be more than ten times, it is not a problem.

After Dugu Jian roughly observed the Xuanhuo Jian, he began to arrange the formation.

The sword qi was born out of thin air, and eight hideous-looking fierce god totems were carved around the Dugu Sword.

The ancient patterns connected the eight totems together, and the entire Eight Fierce Xuanhuo Array became brighter and more red, like a burning fire.

"Step away."

"Yes."

Xiao Bai jumped to the side and watched Dugu Jian cast the Eight Fierce Xuanhuo Array, and his heart was shocked, he actually made a lot of adjustments to the Eight Fierce Xuanhuo Array in Incense Valley in just a few days.

"Kai."

Dugu Jian's voice fell, and the Xuanhuo Jian flew into the air, becoming the eye of the entire Eight Fierce Xuanhuo Array, and the circle began to operate.

The Eight Fierce Xuanhuo Array connects the volcano under the Xuanhuo Altar, absorbing the power of the earth and providing a steady stream of energy, so that there is no need for Dugu Sword itself to provide energy, and the magic circle itself can be maintained by the power of nature.

"Shrink."

Dugu Jian once again controlled the magic circle, and the size of the magic circle shrank from covering most of the third layer to half a meter around Dugu Jian's body.

Because the realm of the circle shrank and the energy was concentrated in one place, the temperature in the array instantly increased by a hundred times.

Dugu Jian readjusted the temperature in the circle, controlling it to a level that was just enough to cause damage to himself, but not too tragic.

Then, Dugu Jian let go of his body and mind, no longer resisted the Eight Fierce Xuanhuo Array with his own strength, and allowed the scorching heat to invade his body, and even took the initiative to suck the fire into his mouth and stomach, allowing the flames to fully scorch every part of his body......

The "Xuanhuo Alchemy Technique" has entered a passive operation state.

Because of the immortal body, the burned body will actively regenerate, and in the process of regeneration, Dugu Sword's own spiritual power will participate in the repair process, strengthening all the reborn parts.

Every time the repair is completed, Dugu Sword's body will be one point stronger than before.

Of course, this process is extremely long and extremely painful.

Fortunately, Dugu Jian is very witty, and took the initiative to cut off his own pain nerves, so he can't feel anything, you can hurt you, I will continue my cultivation......

……

And just like that, the days passed.

Dugu Jian's body is scorched by the flames, and every time it is reborn, it will become more powerful.

When he was tired from cultivating, Dugu Jian would take a pinch of Xiaobai, or let Incense Valley send some food to enjoy, and the days of cultivation were not so boring.
