Doupo: His understanding is incredible, and he shocked Yao Lao at the beginning!

After arranging tasks for Liu Ling, Xiao Yan began to work on his own affairs - upgrading the flying fighting skills!

Generally speaking, the greatest value of flying fighting skills is in the early stage.

Because the most powerful effect of flying fighting skills is to have the ability to fly before advancing to the Dou Wang realm. Secondly, the double wings of the flying fighting skills can be superimposed with the wings transformed by Dou Qi, bursting out a speed that is not weaker than that of Dou Zong strongmen.

Such a strange fighting skill is almost negligible for Dou Zun-level strongmen.

However, one of the most important reasons is that the flying fighting skills are not of high quality.

The fighting skills of Dou Qi Continent are divided into four levels: Huang Xuan Di Tian.

The appearance of flying fighting skills at the Xuan level is already extremely rare, and the flying fighting skills at the Di level are only available in several surrounding empires, plus the Black Horn Region, and only one Tianyan Jiuxing Wing has appeared, which is enough to prove its rarity.

The fighting skills of the earth level, even the flying fighting skills, are no longer suitable for the powerful strength of the Dou Zun realm. If the strength is further improved, the gap between Dou Zun and Dou Sheng is like a natural chasm, and the effect of ordinary flying fighting skills will be even more negligible.

But if the flying fighting skills can be upgraded to the heaven level, or even higher, Xiao Yan believes that this flying fighting skill is still a very useful fighting skill.

He twisted the best storage ring that was offered, and a monster corpse suddenly appeared not far from Xiao Yan.

The body of the monster corpse is more than ten feet wide, but it has been dead for a long time, and its bones and flesh are all in a state of wind drying. The most eye-catching thing about this thing is the pair of giant wings that have become white bones.

This pair of giant wings is quite strange, like jade, emitting a faint fluorescence. Anyone with a discerning eye can see that there is actually some strange energy contained in these wings.

This mummy of the demon beast was exactly what was searched out from the Black Emperor Sect's treasury, the mummy of the seventh-level demon beast, the Sky Demon Phoenix!

Although he had always known about this thing, Xiao Yan still saw it in person.

With light steps, Xiao Yan stopped at the pair of jade bone wings that were about two or three feet wide, then squatted down and gently stroked the bone wings with his palm.

It was cold at the touch, but in this coldness, there was a trace of warmth. It was hard to imagine that this mummy that had been dead for who knows how many years could still emit heat.

This pair of jade-like bone wings was slightly transparent, so it was very easy to see the strange energy wandering around in the bone wings.

After understanding the characteristics of this bone wing, Xiao Yan flicked his finger and shot out a touch of Emperor Flame, and began to burn the remaining meat of the Sky Demon Phoenix mummy.

Under the terrifying temperature of the Emperor Flame, waves of terrifying heat penetrated into the meat.

The terrifying white flesh didn't even make a hissing sound, but under the burning of the Emperor's flame, blue-red blood emerged.

Seeing the blue-red blood, Xiao Yan took out the jade bottle of excellent quality from the bone flame ring and collected the blood.

After all the flesh of the mummy was burned clean, Xiao Yan got five drops of blue-red blood.

Looking at the five drops of blue-red blood in the jade bottle, which were in one place but could not blend with each other, Xiao Yan was a little surprised.

After all, this thing came from a demon beast, and it was independent. It was worthy of being the blood of the best demon beast among demon beasts.

After the flesh and blood were refined, the dry skin of the Sky Demon Phoenix was not affected by Xiao Yan's powerful fire control ability.

A drop of blood was ejected from the jade bottle and fell on the dry skin.

As soon as the blue-red blood fell on the dry skin, it quickly melted into the dry skin. Immediately, the gray-white dry skin seemed to be stimulated violently, and it began to wriggle like a snake. A blue-red color quickly spread out from where the blood fell.

The speed of this blue-red color spreading was extremely fast. In just a few blinks, the dry skin was completely changed. The gray-white color was replaced by a strange blue-red color, which was completely different from before. Moreover, when the blue-red color spread, the dry skin that had been motionless all the time gradually emitted amazing energy fluctuations.

Looking at the dry skin that had changed greatly, Xiao Yan immediately ejected a wisp of Emperor Flame again and tempered the skin of the Heavenly Demon Phoenix.

Although it was just skin, it contained the energy of the Heavenly Demon Phoenix Demon Core.

Under the high temperature of the Emperor Flame, the blue-red monster skin released wisps of special energy mist, like a special blue-red cloud, releasing waves of energy fluctuations that made the Douhuang feel pressured.

As the Emperor Flame continued to burn, the blue-red mist became thicker and thicker, and there was a strange roar in the air.

When the last ray of energy was refined, the beast's withered skin had turned to ashes.

A vortex suddenly appeared in the blue-red mist, enveloping the blue-red clouds, and the volume of the entire energy cloud began to shrink slowly at a speed visible to the naked eye.

Not long after, when the blue-red clouds disappeared, a dazzling blue-red light suddenly appeared in the vortex.

In the strong light, a blue-red crystal with a slightly irregular shape was suspended in the air without any support.

As it slowly rotated, fine blue-red rays of light emanated, and just these leaked energy rays caused the surrounding space to slightly distort.

"The magic core of the Heavenly Demon Phoenix has also come out." Xiao Yan took a deep breath, and his eyes burst into an astonishing heat.

Although it was only the material of a seventh-level demon beast, with the Burning Art as the starting technique, he did not think that the value of this thing would only be at the seventh level.

Looking at the bone wings, blood, and magic core separated from the corpse of the Heavenly Demon Phoenix, Xiao Yan calmed down and swallowed the remaining four drops of blood in one gulp.

Although there were only four drops of blood refined from the corpse of the Heavenly Demon Phoenix, just smelling it would have the effect of increasing strength.

However, Xiao Yan was not doing this to increase his own strength.

After swallowing the blood, Xiao Yan threw the bone wings and the demon beast behind him. With a thought, two pairs of gorgeous fire wings emerged, instantly wrapping the bone wings and the magic core, and releasing terrifying temperature.

In order to use this demon beast material to evolve the flying fighting skills again, it is necessary to refine the residual breath of the demon beast in the material.

For materials of the seventh-level Heavenly Demon Phoenix, even if a Dou Zong strongman wants to refine it, it will be a headache.

However, Xiao Yan possessed the soul-killing Super·Falling Heart Flame, which was the best at removing the remaining breath of demon beasts.

Under the calcination of the Super·Falling Heart Flame, the bone wings quickly responded, and strands of gray airflow that seemed to be substantial quickly penetrated out.
