Spirit stone, Lin Mu had already come into contact with before.

Earlier, the power core of the Heavenly Rank puppet that Lin Mu obtained from Xu Zhao's Rebellion was a medium-grade spirit stone!

Medium-grade Yang Spirit Stone!

It is this spirit stone, Lin Mu is very rare, and he wants to break it and use it as a hundred.

Even in Lin Mu's previous life, he had never heard of a spirit stone vein! Maybe it's because he doesn't have enough contact with the level, maybe it's because after those forces discovered the spirit stone veins, they all hid them, tightened the rumors, and made a fortune in the ground!

But in the world of mythology, there are a lot of rumors about spirit stones!

Lin Mu, who likes to hear anecdotes, has heard a lot.

In the library of Xu Fu Town, Lin Mu had also seen information about the spirit stone.

There are countless veins in the mythical world, but the ones that can make people rich overnight, the spirit stone veins are the most typical examples.

If you want to say that the stone is the most valuable, you have to mention the two spirit stones in the mythical world!

[Yang Spirit Stone] and [Yin Spirit Stone]!

To analyze these two spirit stones, we have to start with their origins.

What is a spiritual stone vein?

The spirit stone is the ore formed by the condensation of the spiritual energy of heaven and earth. It is the essence formed by the transformation of gaseous state into solid state after a long period of precipitation in the thick earth or other rather strange places!

Where heaven and earth are rich in spiritual energy, spiritual stones may not necessarily be born.

The birth of the spirit stone needs to have an origin, which is called the spirit source!

The spiritual source is the foundation of the formation of the spiritual stone vein!

Based on the spiritual source, it gradually absorbed the spiritual energy of heaven and earth, and after endless years of accumulation, it slowly formed a vein with countless spiritual stones!

Therefore, without the spiritual source, there will be no spiritual stone veins.

After the spiritual source in the spirit stone vein is dug up, this spirit stone vein will gradually be abandoned, which is equivalent to the earth that has lost the sun!!

……

Since the Spirit Stone is a pure aura condensation, it is of great help to cultivation!

Spirit stones, according to the amount of spiritual energy condensation in them, can be divided into four grades: lower-grade spirit stones, middle-grade spirit stones, high-grade spirit stones, and top-grade spirit stones!

The exchange ratio between the four is 100:1.

The price of spirit stones, to be honest, does not have a law, because this kind of thing is a rare cultivation resource in the Han Dynasty, and its circulation is very small, and it is generally in the form of barter, which is circulated among military generals and strategists.

The spirit stone is a very high-end cultivation material, which is more pure than the resources such as spirit feasts, pills, and herbs that you usually eat!

Between heaven and earth, there are two qi of yin and yang!

After the spiritual source absorbs the yin and yang qi between heaven and earth, it will form two spirit stones with different attributes, which is the origin of the yang spirit stone and the yin spirit stone.

Yang Spirit Stone has a wide range of uses, even if it is a practice of cultivating femininity, it can also use Yang Spirit Stone to assist in cultivation. As for the Yin Spirit Stone, it has very big limitations. It can only assist those who are cold and dark practitioners, such as Li Dian Yu Ban and others, and they can't use Yin Spirit Stones to cultivate casually.

The night shadow of the Night Shadow Department can be cultivated with two spirit stones, yin and yang.

Of course, it is not impossible for Yu Ban Li Dian and other generals who take a strong path to cultivate, but the rate of their absorption is very low, which can be described as turtle speed.

And the Night Shadow of the Night Shadow Department, the speed of using the Yang Spirit Stone to cultivate is also much lower than the efficiency of using the Yin Spirit Stone.

This is a relative issue.

……

Lin Mu knew that a low-grade Yin Spirit Stone could allow a ground-level martial artist to accelerate his cultivation for three days!

This information was summarized by the Night Shadow Department. The Night Shadow of the Night Shadow Department can be used with spirit stones, because Lin Mu opened up the path to the ghost city of Xudu early, allowing [I am a legendary merchant] to enter it and buy Yin spirit stones in a big way!

The improvement of its strength can be improved day by day, because it is assisted by a large number of Yin Spirit Stones.

………………

At dawn in the sky, the morning sun gradually rises, and the brilliant red light reflects the skyline.

When Xi Zhi discovered the Yin Spirit Stone vein, the battle on the Ghost Peak outside also entered a white heat.

Because of the limitations of the cultivation system of the eight living dead, the eight battlefields did not have the same explosive and stormy aura as the generals of the Great Wilderness Territory and the Taiping Dao before.

This battlefield is more appropriate to describe with the word hand-to-hand combat.

Eight battlefields, in a semicircular arc, are distributed on the top of a very wide hillside.

Huang Zhong's battlefield is located at the top of the arc, starting from the top of the arc and to the right are Yu Ban, Jiang Qin, and Li Dian; And to the left, it's Feng Zhong, Zhou Tai and Zang Ba!

Feng Zhong is limited in the mythical world because his divine power is limited, so his strength is just the strength of a peak of the ground level!

However, even if Feng Zhong's current strength is at the pinnacle of the ground level, his assistance to the battlefield is indeed indispensable!

Feng Zhong continued to use his skills, and the Huangquan Heavenly Nine Formations came to assist everyone.

Feng Zhong's Huangquan Dutian Nine Array is a heart array skill, that is, there is no need to use materials to arrange and depict array inscriptions and runes like Xu Yuan.

The heart array can be used as much as you want, as long as the divine strategy and internal force are enough to squander.

Divine Wisdom is a subsidiary attribute derived from intelligence, some skills will use the support of Divine Strategy, and some skill specialties are not required.

Especially Lin Mu, who was transferred to the Honghuang Dragon General, his divine power seems to be dispensable to him at present. Lin Mu has not yet learned the skills and specialties of the strategy class, and his divine strategy power has never been consumed.

And the specialties and skills of Yu Ban, Zhou Tai and others belong to the commander's strategy category, which requires a lot of divine power.

The assistance of Yu Ban and other generals has always been added to the soldiers, which is also one of the reasons why the Great Wilderness Territory is extremely fierce!

In the battlefield, in addition to Feng Zhong's assistance, Yu Ban Zhou Tai and other assistants are not bad, if there are players in the same camp as them, seeing such a series of auxiliary buffs, they will definitely be shocked that their eyeballs will fall.

The assistant to the pinnacle of the mythical world, that's basically it!

Compared with the assistance of Zhou Tai and other military generals, Huang Zhong's assistance state seems to be a little backward. Huang Zhong's assistants are basically focused on the archers, or his own blessings, which is inferior to the buffs of the whole army such as Forbidden Zhou Tai.

Of course, the eight ferocious generals, after blessing each other, were like gods descending from the earth, fighting fiercely against the eight invulnerable living dead with endless power.

Among them, the most ferocious and fierce battlefield was the fight between Huang Zhong and the golden armor corpse.

Huang Zhong swung the big knife and kept slashing at the golden armor corpse, and the sound of countless metal collisions spread out and rattled.

"These living dead, after experiencing the tempering of the yin veins, the tempering of the years, and the washing of the moonlight, are really invulnerable!" Huang Zhong slashed hard, splitting the golden armor of the living dead back a step and shouting loudly.

When the others heard this, they all nodded involuntarily and felt the same way.

Huang Zhong kept swinging his broadsword, taking light steps to dodge the enemy's attacks, secretly frightened.

"I used my divine power to assist, but I couldn't even break through his defenses, this defense is too desperate!" Huang Zhong said again.

"Maybe it's better to use the Blood Spatula to destroy its defenses as planned, so that you can kill these living dead." Yu Ban leaned on one side slightly, and after dodging an attack, he said in a loud voice.

"No! Didn't the military advisor say it before, these eight living dead people have the Spirit Pill in their bodies, and after using the essence blood, it will hurt the Spirit Pill. ”

"It's also fortunate that these living dead don't have too high intelligence, and only rely on the fighting instinct of their previous lives, otherwise, we wouldn't have dealt with it so easily." Zhou Tai fought against the living dead in front of him, quite easily.

"You can only wait for the military advisor to destroy the formation in the tomb palace before you can find a chance to break the situation!" Li Dian struggled to cope with the enemy, his brows furrowed.

……

Huang Zhong frowned slightly, and his face was quite solemn. But Huang Zhong's bright eyes still showed a glow of interest.

The living dead, he had only learned about it in some classics, and now he was fortunate enough to see the murderous and living dead appear in front of him.

Although he had heard the relevant information from Xu Yuan and others earlier, when he faced the enemy, he experienced it first-hand and saw it with his own eyes, which inevitably shocked his heart a little.

Huang Zhong's whole body strength slammed up, and he swung his sword fiercely and slashed forward, fierce and invincible, but the opponent was neither mortal nor human!

I saw that the skin that was like platinum paper was shining, and every time Huang Zhong slashed at his body, the glowing skin would instantly tremble.

The golden living dead, all the organs of the whole body, seem to be tough and sharp.

It waved its arms with a cold, metallic sheen and wrestled with Huang Zhong. Those hands that have been tempered for thousands of years, and ten golden fingers that are as hard as diamond drill bits, can brazenly take Huang Zhong's big knife!

You must know that in the previous battle with Dian Wei, Huang Zhong only took over Dian Wei's halberd blade once, and he didn't have it since, because the price paid and the gain were disproportionate.

However, for the living dead, it was as easy as a daily routine.

"Bell !!" A piercing sound of metal clashing suddenly sounded.

The five fingers of the golden armor living dead man's left hand slammed into force, tightly grasping Huang Zhong's knife. And with his right hand, he grabbed Huang Zhong's head fiercely, and the whirring whistling sound made people's scalp tingle.

Huang Zhong, in the face of the enemy's brazen blow, did not panic, staggered slightly, drew his knife suddenly, and the whole person was separated from the enemy.

And the right hand attack of the golden armor living dead did not stop because of Huang Zhong's push, but instead violently grabbed a stone on the hillside.

"Boom!" The right hand, as hard as a diamond, tore the stone of the hillside into rubble and burst out.

These devastation are not at all a level compared to the devastation brought about by the previous battle of Dian Wei and Huang Zhong. But the danger is compared to some of them.

If he was hit his body, even if it was Huang Zhong, the Divine Power Gang Mask would respond to it, and maybe he would be injured a little.

On the slope of the Ghost Peak, it was already black and withered, but after the appearance of these eight battlefields, it became even more bare.
