After killing the old woman, the surroundings returned to silence...

Heather did not hesitate and jumped directly into the spring pool. Entering it, he felt a sense of comfort, as if all the pores in his body were opened.

The spring pool is very deep, not ordinary deep. But this just proves that what Heather thought was right. The bottom of the spring pool is the source of this spiritual energy!

Heather quickly sank down, descending about twenty meters, and finally reached the bottom. At this time, he could feel a burst of extremely strong spiritual energy emanating from a certain location under his feet.

The spiritual water should be formed by the upwelling of underground water. All you need to do is find the entrance of the cave.

Heather unleashed his energy and searched the bottom of the spring. A few minutes later, he found a hole at the edge of the bottom of the spring. The spring water gushes out of this hole!

Heather didn't hesitate and swam directly in. After that, there was a dark passage.

Heather was extremely excited because he knew that he was getting closer to the source of spiritual energy. After passing through the dark passage, a dazzling blue light appeared in front of him!

Looking at the scene in front of him, Heather's eyes were filled with excitement. This was a spiritual vein that was more than 300 meters long and glowed with blue light!

Spiritual energy is absorbed by the ores in the earth's veins to form spiritual stones, and the earth's veins absorb a large amount of spiritual energy to form spiritual veins.

Ley vein ores contain various chemical elements, which cultivators call impurities.

Different earth veins contain different impurities, and even if it is the same earth vein, each section of the earth vein contains different proportions of impurities, so spiritual stones of different purity are produced in the spiritual veins.

The closer to the center of the spiritual veins, the higher the spiritual energy content and the fewer impurities in the collected spiritual stones. If the spiritual stones are divided into grades according to the spiritual energy content, they are divided into four grades: lower, middle and upper.

Lower grade: Lingshi with a spiritual energy content of 50% to 70% and low transparency, which is lotus root pink, bean green, light green, and milky yellow (the Lingshi has no spiritual power properties, and the color is caused by the penetration of impurities), containing cotton wool or sesame seeds

There are obvious flaws in the shape. This type of spirit stone is mainly used in small formations or cheap machinery and teaching equipment, and is often mixed with monster beast cores.

Medium grade: 70% to 80%, spiritual stone with slightly higher transparency, including dark red, brown red, ocher red, duck egg blue, sky blue, green seedling, etc., with a greasy luster, no obvious flaws or few flaws to the naked eye. This type

Spiritual stones are often used in small and medium-sized formations; to provide energy for mechanical equipment such as fighter jets and tanks; for heather, medium-grade spiritual stones are commonly used to provide energy for automatic alchemy furnaces.

Top grade: 80% to 90%, with glass luster and good brightness. It is usually only produced in mines in areas where the five monsters are densely populated. Other flowing veins are sporadically produced. Most of them are white, milky white ice-like translucent crystals.

There is no blemish to the naked eye, and there are also fish belly blue and light green.

Color, moon white production. This type of spiritual stone is generally used in large-scale formations such as formations in dense areas of monsters; to provide energy for large machinery such as aircraft carriers and spiritual power submarines; and in addition, it is used in scientific research computers, precision testing instruments, etc., as well as

Some special spiritual weapons and mechanical equipment.

Top quality: 90% to 95%, with very little output. The few existing ones are pure and transparent colorless crystals, large in size and with strong spiritual power. As important energy reserves for the country and several major forces, they are generally not easily

use.

For thousands of years, earth cultivators or people with supernatural powers have needed to use the aura contained in spirit stones to enhance their strength. In modern times, its wide range of applications has been gradually discovered, and spirit stones have become the hard currency of the earth.

In the past, every major immortal cultivating sect would have a spiritual vein within the sect. The spiritual vein is the foundation of a sect, and it is also the lifeblood of a sect. Although most of the spiritual veins have been nationalized in modern times, there are still some

It has been rumored for countless years that the powerful sect possesses some spiritual veins.

The two world wars that have occurred on earth were triggered by the fight for spiritual veins. It can be said that the value of a spiritual vein far exceeds the value of an ordinary modern sect!

"Damn it, I'm not dreaming...I can actually find such a big and long spiritual vein!?" Heather even couldn't believe it.

Heather has been a human being in two lives, and the differences between the two lives have smoothed his character. But facing this spiritual vein, he can no longer remain calm!

This is a whole spiritual vein! But it now belongs to Heather alone!

Whether he absorbs the spiritual energy or uses it as money, the benefits it brings to him are self-evident.

Heather no longer hesitated and moved toward the spiritual pulse.

"Boy, stop immediately! You have trespassed into the forbidden area of ​​our Supreme Valley, and you want to attack the spiritual veins of our Supreme Valley?" At this time, a deep voice, like thunder, penetrated into Heather's ears.

"Supreme Valley?" Heather was a little surprised. There are only a dozen sects in China with spiritual veins, and they are all registered with the Cultivator Administration Bureau and can be found online. Heather thought quickly, but she had no impression at all.

"I am the guardian of the Supreme Valley. If you come even half a step closer, I will kill you immediately!" The other party was quite angry.

"If you could kill me, you would have killed me long ago, so why bother talking?" After saying this, Shi Nan ignored him and quickly swam towards the spiritual veins.

Floating out from the depths of the spiritual vein【299】

"Boy, die!" the guardian roared, and the power of the sound wave made the calm water bottom faintly tremble.

Suddenly, a whirlpool spread from the spiritual veins. The water was swept away by the whirlpool, and a huge force began to tear the heather around.

Ordinary cultivators, even those in the foundation-building stage, would probably be crushed into pulp in an instant if they encountered such a huge force.

But Heather didn't even change her swimming posture and looked indifferent.

The area where the spiritual veins are located is very wide, several thousand meters wide.

The spreading whirlpool was extremely turbulent. Suddenly there was a strong aura in the spiritual veins approaching the heather, and a huge figure became clear in the whirlpool, and then a huge blue dragon head emerged, with a pair of huge eyes.

His eyes were staring at Heather with some dissatisfaction.

A 1.8 meter human being is not as big as its eyes, the gap is too big, Heather is like a tiny person in front of it.

The huge dragon head suddenly rose into the sky, and only then did Heather see the appearance of this giant dragon clearly. Its whole body was covered with blue scales, and it had a body nearly a hundred meters long. Each of its four limbs had three fingers on its claws.

The moment Heather saw it clearly, the huge head suddenly pressed down and swooped in, biting directly at Heather with its bloody mouth.

Heather looked at the giant dragon that was swooping down, especially the teeth in the huge mouth. They were extremely sharp, but had rust stains. Heather looked carefully at a large gear that attracted him, which showed that this was not something at all.

What kind of creature is it? It's a machine made by an ancient sect.

Seeing that the big mouth was about to swallow up the heather, but...

Heather was not in a hurry to evade, but calmly suspended in the water and watched, watching the bloody mouth approaching quickly!

"Huh?" The mechanical dragon obviously hesitated for a moment. It was a little confused, why didn't this human hide? Do you want to resist him head-on? If a human foundation-building cultivator dares to confront him head-on, isn't he looking for abuse?

"Stab!" Heather suddenly shouted.

Buzz!

A sword energy merged three kinds of flames, and also contained the penetrating sword intent, and it immediately flew towards the swooping mechanical dragon! The entire mechanical dragon's body suddenly tightened, and it seemed that invisible power penetrated the whole body from beginning to end.

Everywhere! Following the mechanical dragon, it flew backwards. Although its sinuous body was twisting and struggling, it still couldn't withstand the sword energy.

Flying upside down at high speed!

"Boom!!!" With a loud noise, the nearly 100-meter-long mechanical dragon was directly stuck to the wall of the cave at the top of the spiritual vein area like a big cake! Its body was still twisting and struggling, and some parts began to fall down.

Fall.

Fortunately, there was a magic circle protecting the spiritual veins and it was not damaged at all. Otherwise, with such impact force, an ordinary cave would have collapsed long ago.

"If I hadn't stayed here for too long, you would have been little..." The mechanical dragon's body was twisting, and more and more parts on its body were falling off.

Indeed, this mechanical dragon has been here for who knows how long, and no one has maintained it. In addition, it looks like it has water properties, but it is actually metallic, and it is restrained. Otherwise, Heather's sword energy would not have such a good effect.

But who made its sect disappear in the endless years?

Soon, only the upper half of its head was left of its huge body! When the two corners were lowered, a blue dodecahedron split open in the middle of the head.

The blue dodecahedron floats out【799】

"I, I..." The blue dodecahedron issued the voice of the guardian of the mechanical dragon. His tone was full of anger, but only the core was left to make it helpless.

Finally, after a few seconds of silence, its tone was full of unwillingness and helplessness, and it let out a low growl, "I lost!"

With a move of his hand, Heather used his spiritual power to pull the dodecahedron into his hand.

"Boy, I have been here for more than three thousand years, and you are the first human cultivator I have seen. I have nothing else to ask for, I just want to know if the Supreme Valley is still there?" the dodecahedron made a pleading voice.

.

"I said, I have never heard of the Supreme Valley. Is this your core? What kind of monster are you refined from?" Heather was also full of questions. She thought it would take a lot of effort to refine it.

He was defeated, but he didn't expect that he could solve the problem with just one sword strike.

"Hey, it seems that the Supreme Valley no longer exists. My name is Ao Min. I was originally a dragon. My body was broken into pieces by human cultivators, leaving only the Nascent Soul. I met the owner of the Valley by chance, and he made me a new one.

Body, my strength has also reached the Dongxu stage one step closer. The Valley Master asked me to guard the spiritual veins,

He came back from time to time to repair this body for me. Unfortunately, one day I heard that there was chaos in the valley, and shouts of killing were everywhere... I have never seen anyone since then..." Ao Min still couldn't accept that he was being killed by a person.

The boy in the foundation building stage was defeated and recalled various past events.

Shinan took Ao Min's core and swam towards the spiritual veins, and said to the core: "Don't worry, I can help you find Wu Valley, but I can't guarantee you whether I can find it."

"Thank you..." Ao Min's tone was full of gratitude, and he paused and continued: "There is a book about machinery in this spiritual vein, which was left by the owner of the valley to facilitate the maintenance of my mechanical body by future generations.

"

"Oh? Does that mean your parts are still usable? As long as I help you repair them, you can return to your peak strength?" Hearing this, Heather was shocked.

"It stands to reason... yes, but don't worry. As long as we sign a contract, you will be my master." As he said that, a purple circle appeared around the core, covered with runes, but Heather didn't recognize any of them.

"Ignore it, this is an equal contract between spiritual beasts and humans." Xiao Ling appeared in front of Heather, crossed his arms and said with disdain.

Heather stopped, stared at the Ao Min core in his hand, and said: "Equality contract? If you want me to help you regain your strength, sign a master-servant contract, my master, your servant!"

【99】 floats out from Ao Min’s core

"You...you have to push yourself further!" Ao Min said angrily.

"Like to sign or not! Today's mechanics are not comparable to those of your time!" Shi Nan nonchalantly put Ao Min's core into the five-pointed star space magic weapon.
Chapter completed!
