Wing training doesn't have a variety of levels like practice.

As long as there are materials, Zhang Xuezhou's wings can continue to be practiced after the tempering and cooling period.

Just as as there are enough materials to build a blade, as long as there are enough materials, Zhang Xuezhou can also continuously improve and transform his wings.

In the "Cloud Technique" explained by Venerable Lei in the future, Zhang Xuezhou knew very well that the pair of wings on his body had the possibility of training meat wings, wooden wings, iron wings, copper wings, golden wings, jade wings, and wind and thunder wings.

Flesh Wings are the wings he originally possessed, and when this kind of wings are raised to the limit, they will enter the Wood Wing stage.

Wooden wings do not mean that they are rigid, but they mean that they are beginning to have the ability to soar for a long time like a ship that can float in the sea.

If the wings of the flying bird demon have the level of Zhang Xuezhou's current wings, the opponent's flying ability has at least doubled or tripled, and he has an extremely long-term soaring ability.

Zhang Xuezhou can only fly 30 miles, which is related to his halfway monkhood and the reason for his personal condition.

In the practice of "Cloud Technique", this situation was extremely normal for him.

Even Venerable Lei was only able to fly tens of miles when he first cultivated.

On top of the wooden wings are iron wings, this level of wing feathers are like iron sheets, with iron wings not only make the ability to fly stronger, but also have the ability of iron wings to protect themselves, and resist the blows of feather arrows in the air.

With the help of the resources of Wuchao, Zhang Xuezhou completed the collection of wings and also completed the transformation to wooden wings.

Right now, he's on his way to the stage of iron wings.

The materials such as Mithril, Zhu Dansha, Yunying, High-grade Blood Jade, Iron Meridian Ginseng, Cloud Grass, and Yin Jujube that were originally required were no longer able to meet the requirements, and they were turned to materials of a higher level.

Zhang Xuezhou sat in the carriage and looked at the century-old iron essence in his hand with a solemn face.

"Senior brother, can this kind of iron lump really fit into your arm?"

Zhang Xuezhou was dignified, and Wuchao was also curious, it was difficult to imagine how a piece of iron could be integrated into the human body.

Centennial iron essence is a very high-grade casting material, which is born from extremely high-quality iron ore and belongs to the essence of iron.

The hundred-year-old iron essence born in an iron mine is only more than ten catties, and the quantity is extremely rare.

But a person's arm is not an iron tool, and in the absence of a furnace, how can Zhang Xuezhou melt this iron lump.

And thinking that Zhang Xuezhou's body forcibly poured this kind of iron lump into his body, Wu Chao shuddered in his heart, and felt that the cultivation method of this technique seemed to be extremely extreme.

"Fusion can still be integrated!"

Zhang Xuezhou nodded and began to prepare the solution again.

Rao also has a certain amount of chemical knowledge, and Zhang Xuezhou did not fully understand the principle.

No matter how rare the iron essence of a hundred years and a thousand years, this is a piece of metal with extremely high purity.

This is really the need to dissolve this piece of metal, and then absorb this dissolved liquid into the wings by smearing, and then continuously temper the wings through the operation of the exercises.

"It's unscientific, it's unreasonable, I don't need to supplement iron in this way......"

All kinds of thoughts swirled in Zhang Xuezhou's mind, and in the end, it was experience that overcame Zhang Xuezhou's reason.

He was not the first person to practice the "Cloud Technique", and there is still a living cultivator in the Holy Land of the Tuo Yu River.

Zhang Xuezhou didn't understand the principle of cultivation, but if he practiced in the way that his predecessors had already succeeded, he would not die.

"What is this thing, it actually dissolves all the iron essence, and this kind of thing is applied to the hand, so it can be returned?"

Seeing that in the solution prepared by Zhang Xuezhou, the hundred-year-old iron essence continued to dissolve into a mass of black-red substance, and Wu Chao only felt that the liquid prepared by Zhang Xuezhou had a stronger effect on his body than the corpse water.

Correspondingly, Zhang Xuezhou is likely to lose his arm when he plays like this.

Watching Zhang Xuezhou practice "Cloud Technique", Wuchao couldn't help but be a little frightened, feeling that the other party was practicing with his life.

"Senior brother, don't worry, a solution that can dissolve iron may not dissolve your hands!" Zhang Xuezhou waved his hand and said, "I just feel that this thing melts into my arm, and my weight is likely to increase!" ”

"Uh, that's what you're worried about?"

The black nest was stunned.

He felt that his brain circuit was completely different from Zhang Xuezhou, and what the other party was worried about was not on the point at all.

"Don't worry, no, there's a lot of stuff stuffed into your arm in the back!" Zhang Xuezhou had a headache and said: "Stuff two catties today, stuff three catties tomorrow, and stuff ten catties the day after tomorrow, I feel that my limbs are likely to be uncoordinated." ”

"How is it not coordinated?"

"Compared to my body, my arms are probably too heavy to walk!"

"It's okay if you don't move your hands when you walk!"

"You're right!"

"And you're not a martial artist, heavy arms won't lower your martial arts level!"

"Makes sense!"

Zhang Xuezhou nodded.

He looked at the blood-like solution, and when Mithril was blended, Zhang Xuezhou began to frown and smear the thin lines of his arms that hid his wings.

The wings of "Cloud Technique" are more like smelting a physical magic weapon.

In the introduction of the Thunder Venerable, the ancestor of the Thunder Venerable, not only has the wings of wind and thunder, and the level of flying is the first in the world, but also has a magic weapon-like body, and has great power when striking.

Zhang Xuezhou felt that this is how Lei Zhenzi's body magic weapon came about.

His current behavior is to make his wings into magic weapons, and even need to add Mithril, the material for forging magic weapons, every time.

Zhang Xuezhou only tempered his wings, and Lei Zhenzi probably tempered his whole body.

This made Zhang Xuezhou swallow his saliva, and it was difficult to know how the other party's body could withstand this kind of construction.

The numbness and itchy feeling of his arm came, and Zhang Xuezhou took a deep breath.

He looked at the sky outside the car, then took his mind back.

"Senior brother, you help me slowly brush this solution on my arm until I finish brushing, I'm going to sleep!"

Zhang Xuezhou's arm numbness and itching were difficult to stop, and he couldn't scratch his skin, Zhang Xuezhou finally felt that he had slept well.

After all, in that state, Zhang Xuezhou didn't care about what happened to his body at all.

"Can I help you? Can you practice so casually? ”

Wuchao also looked at the sky, and knew very well that the time for Zhang Xuezhou to fall asleep was coming.

But he had never seen this kind of cultivation.

It doesn't matter if the body is integrated into the iron bump, the key is that Zhang Xuezhou showed the previous steps, and the back was directly handed over to Wuchao to do.

Wu Chao felt that the practice of "Cloud Technique" was too casual.

In addition to consuming too many cultivation resources, this technique can be called the least worry-free cultivation that Wuchao has ever seen.

"Senior brother, you can definitely do it, the time or so for you to help me apply three sticks of incense should be almost finished!"

Zhang Xuezhou nodded, and he forcibly pressed his right hand that wanted to scratch his arm and tickle.

No one can stop the itching sensation under this numbness of the body, and without the help of someone, this technique cannot be practiced at all.

"When others practice, they may be smeared after being knocked unconscious......"

Zhang Xuezhou handed the solution to Wuchao, and after the thought came to his mind, he immediately collapsed in the carriage.

"Senior brother's cultivation of this kind of technique is really enviable!"

Wu Chao just thought about the spell practice that he never dared to relax, and compared Zhang Xuezhou's spell practice, he felt that people's lives were simply different.

The only flaw of Zhang Xuezhou's practice is that it consumes resources.

With the help of the requisition of royal resources, Zhang Xuezhou entered the second stage of the cultivation of "Cloud Technique", but in the third stage, there was a lack of a material called Bodhi fruit, and it was difficult for even the royal family of the fierce country to recruit this material.

This is likely to put Zhang Xuezhou's practice in a bottleneck.

After thinking about it for a while, he finally adjusted his mentality and balanced his heart.

When the solution was constantly applied to Zhang Xuezhou's arm, Wu Chao occasionally looked at the night outside the carriage.

Zhang Xuezhou's lack of cultivation materials will lead to a bottleneck in his cultivation, and his lack of cultivation resources will undoubtedly lead to a slow grinding of his cultivation.

That's not what the Black Nest wants.

As for the resources needed for cultivation, the Black Nest must strive to obtain the maximum amount of the current level.

Only in this way can he maintain his advantage in the leading position of the corresponding age stage, instead of getting older, the more ordinary he becomes.

For anyone who prevents him from taking the royal family's cultivation resources, Wu Chao will not be polite.
