Generally speaking, the "spiritual root" is divided into five attributes: metal, wood, water, fire, and earth.

This kind of spiritual root, which is mixed with four or five attributes, is called "ethereal spirit root", just like a crystal containing impurities, it is flawed, and its color is greatly reduced.

"Void Spirit Root" practitioners can also sense the aura of heaven and earth, but the effect is not good, most of these people can only practice through the mortal realm, and there is no hope of success in building a foundation.

Some spiritual roots only have two or three attributes, and each attribute has abundant spiritual roots, and this kind of spiritual root is called "real spiritual root".

The cultivation of the "Spiritual Root" cultivators is fast and steady, and compared to the "Void Spiritual Root" practitioners, it is simply incomparable.

There are also people with a single spiritual root attribute, only one of metal, wood, water, fire, and earth, and this kind of person with a single spiritual root is born with a high cultivation talent.

In the country of Rato, a single golden spiritual root is called a "dragon spiritual root", and a wooden spiritual root is called a "tiger spiritual root".

By analogy, the spiritual root of water is called "Jiao Linggen", the spiritual root of fire is called "Phoenix Linggen", and the spiritual root of earth is called "Snake Linggen".

People who have a single spiritual root can practice several times faster than ordinary people, and they can cultivate across levels, and when they are at the peak, they can go all the way smoothly, and they can't hit a bottleneck at all.

Single Spiritual Root Practitioners, especially single Golden "Dragon Spiritual Root" practitioners, are very rare, and only one may appear every hundreds of years.

In addition to this top-level spirit root, there is also another "variant spirit root", which has a higher chance of appearing, one can appear every few decades.

"Variant Spiritual Root" refers to a spiritual root with several attributes mixed together and upgraded due to mutation.

For example, "Wood Spirit Root" and "Earth Spirit Root" mutated and upgraded to "Leopard Spirit Root"; "Golden Spirit Root" and "Wood Spirit Root" were mutated and upgraded to "Wolf Spirit Root".

In addition, there are a variety of "variant spirit roots", such as "fox spirit roots", "wolf spirit roots" and so on.

Practitioners of the "Mutant Spirit Root" do not have the talent to be exempt from the bottleneck, but once the bottleneck is broken, the speed of their practice cannot be underestimated.

Xu Dong read the section "Mutant Spirit Root" and remembered the conversation between the three killers when they were chased and killed in the barren meadow.

"Hahaha! Go back and explain to the sect master, in our Luotuo country, the last 'Morph Spirit Root' practitioner has been killed!"

Could it be that I, Xu Dong, am a master with a "Mutant Spirit Root"?

He had to test his spiritual root attribute as soon as possible.

Later in this section, the method of detecting the spiritual root is attached.

Detecting the attributes of the spiritual root is a complicated technical task, which involves intercepting the spitting and sucking of the tested body, and isolating the almost invisible spiritual root in it.

Then from the color, smell, aroma, density, flexibility and other indicators were analyzed, repeatedly demonstrated, and finally the conclusion was drawn.

However, in order to accurately identify the spirit root attributes, it is necessary to have a first-level inner vision spell.

Xu Dong secretly complained, the half-pulled inner vision technique he learned in Linggumen couldn't even be called the last stream.

He had an idea, and quickly flipped to the magic weapon branch to see if there were any ready-made magic weapons for testing the spiritual root.

There are indeed records of magic weapons, and the magic weapons that detect spiritual roots are: spiritual root detectors, soul reading yin charms, water and fire magic barriers, Changchun immortal gourds, etc.

But it doesn't say where to find these weapons, or how to find them, if the Lotus Cave doesn't have them, then it's a fool.

didn't wait for Xu Dongqi to be angry, his eyes lit up and he saw a line of annotations at the back: When detecting the spiritual root, you can also use the stone curtain to make a tool.

He turned to the section of "Stone Curtain" again, and it was recorded in the book that the stone curtain was originally generated naturally, and the first cave master, "Elder Longyin", used the power of the Dao to ignite the stone curtain before it was feathered.

It took a few more years for this stone curtain to accumulate energy and become a "universal detector" for detecting skills, leveling, and strata.

Xu Dong was extremely excited, with this "universal detector", he would be able to know his cultivation progress at any time in the future.

He quickly memorized the recipe for activating the stone curtain.

Xu Dong meditated in front of the stone curtain, silently reciting the spiritual formula, and there was a place on the stone curtain that lit up with a faint blue light, which was called "opening the eyes of heaven".

He breathed at the open stone curtain, to see what would happen to the stone curtain when his breath was intercepted.

The first to appear was a long horizontal dotted line, like white bubbles rising from the blue water, and as these bubbles burst, golden light appeared.

"Unisex is golden, dragon spirit root?"

These words flashed in the "eye of the sky".

Then, the picture was covered by some garbled characters, and after a long time, these garbled codes slowly clarified, revealing a classical bright yellow wood grain.

"Wood, Tiger Spirit Root?"

There were some garbled codes that swallowed the picture, and then a dazzling light jumped wildly, and the sound and light were very similar to lightning and thunder, and then gradually stabilized, and it was a cloud pattern like a glow.

"The variant of the Dragon Spirit Root and the Tiger Spirit Root, the Thundercloud Spirit Root, is also known as the Flame Storm. ”

Seeing the note in "Sky Eye", Xu Dong was so happy that he was about to go crazy.

"Sure enough, it's a mutant spirit root, oh yes!"

"Oh!"

Xu Dong found the entry for "Thundercloud Linggen", and when he saw it, his eyes were stunned.

Thundercloud Linggen: Also known as Flame Storm, also known as the Heavenly Wolf Tribulation, commonly known as "Thousand Words".

This kind of spiritual root only appears in about a thousand years, and it is a twin male spiritual root.

With the receptor of this spiritual root, there are a thousand calamities in the immortal path, and there will be a thousand bottlenecks when cultivating, and every time there is a bottleneck, the maid will have to re-cultivate.

The reason why it is called "thousand words" is because it is related to "thousand": a thousand calamities, a thousand women, and a thousand souls......

Heavenly wolf cultivators, they must find a female with a "snake spirit root" to match, and practice double cultivation in order to break through the bottleneck.

Once the bottleneck is broken, the practice speed is 100 times faster than that of the "Dragon Spirit Root" practitioners, and 1,000 times faster than that of ordinary "Real Spirit Root" practitioners.

The Celestial Wolf Cultivator was either robbed and killed by others, or sucked dry by the Demon Maiden, or destroyed by the Heavenly Tribulation......

If this kind of spiritual root survives after the catastrophe, it will be the supreme king of the cultivation world.

In the blank space behind the entry, I don't know who annotated the eight characters in light ink: "Wander the world, no more calamity!"

Xu Dong couldn't help but gasp.

"Wander the worlds, no more calamity!"

He groaned, and in order to read between the lines, he pointed to the page with the book in his hand, and read it again and again.

"This kind of spiritual root only appears in a pair for about a thousand years, and it is a twin male spiritual root. ”

It means that in this world, or in the country of Ratuo, at this moment, there is another Heavenly Wolf Cultivator.

This person is his Xu Dong's twin brother, otherwise why is it called "twin"?

Xu Dong naturally remembered his life experience, his life history is still a mystery, and it is likely to remain a mystery forever.

According to rumors, his mother was indeed twins when she gave birth to him.

His mother had a difficult birth, and it took only three days after the seizure to give birth to his brother, who collapsed like a paper man, and no longer had the strength to give birth to him.

Seeing that the adults and babies were not safe, the midwife left with her legs, and his father couldn't do it, so he used a kitchen knife to cut his mother's belly and dragged him out.
