The deep cavern, inlaid with expensive pyroxene lighting, is not too dim. But Cai Qingjia didn't feel good, as if something was always spying on her.

But no matter how much she searched, she didn't know where the feeling came from. There are only rock walls in all directions, and occasionally scattered waste ore can be seen. After the revival of the aura, strange demons often spontaneously form in this dark mine, such as gold-eating ants or yin wind monsters.

The unique demon clans in these pits are haunting and will cause great trouble to the miners. But in the eyes of practitioners, it is not worth mentioning. Cai Qingjia is strong and will definitely not be afraid. But that feeling of vicious hatred has always been with us.

She looked at Su Lei, and the man seemed completely unaffected. Then he opened his mouth and complained: "My dear, even if you hide something, don't hide it in such a deep underground." It makes me feel very uncomfortable here. ”

"Uncomfortable?" Surrey laughed, "Why don't we get comfortable here?"

"Dead ghost!" Cai Qingjia smiled and twisted him.

While laughing and playing, they finally reached the end of the mine. This is a very shallow cave, and the end is only more than 100 meters away from the entrance. Although there were several turns, there was no fork in the road.

There used to be a vein of gold here, but the amount was very small. After less than a year of excavation by the workers of Qianjiao, the vein was depleted and the cave was abandoned.

Su Lei stopped, looked at his lover and smiled without saying a word. Cai Qingjia knew that Su Lei was going to sell off again, and wanted to try his eyesight.

So she cooperated and looked around.

This is already the end of the mine. Cai Qingjia reached out and stroked the rough rock surface, and a trace of aura seeped into the interior through his fingertips. But apart from the stones, there was only a small amount of gold. There is no such thing as a hidden secret door.

"Honey, I really don't see what's going on here. She had no choice but to surrender to Su Lei, "You are such a smart person hiding things, where can I find them." ”

Su Lei was triumphant, he no longer played tricks, but took out a handful of Xuanjin powder and sprinkled it on the ground.

Strange to say, the ground that was originally empty, but because of this powder, a pale golden magic mark faintly appeared. Cai Qingjia half-knelt down curiously to look. This is not a mark that appeared out of thin air, but a structure of the dark gold powder sprinkled by Su Lei, which was affected by an unknown force.

But the form of technique that this highlighted was very unfamiliar, and Cai Qingjia recalled that this was not the type of any kind of technique that the New World Club had mastered. It's no wonder that so many spies have gone deep into this place but found nothing, and Qianjiao has somehow mastered a completely new technique.

She raised her eyes and pleaded, hoping for an explanation. However, Su Lei did not satisfy her this time, he just pouted and smiled, and did not speak. Alchemy is one of his hole cards, and although it is not the biggest hole card, it will not be handed over easily. Su Lei considers himself a cautious person, and now that the surrounding seven cities are not in his pocket, of course he has reservations.

You can't be like the stupid woman in front of you, and you have to explain everything when you get into bed.

He took Cai Qingjia's hand, and several obscure and mysterious runes appeared on his fingertips. The pale golden sigil on the ground was activated, and a curtain of light enveloped them. By the time the light was over, the pit was empty.

In the valley, Master Sun frowned. When Su Lei activated the alchemy, Sun Xiang was sneaking his divine thoughts into the vines of Lishuizhi, trying to find clues to the entrance. The aura fluctuations that the two of them infiltrated into the ore vein happened to be captured by him. Although judging from the fluctuation of casting, this alchemy is quite imperfect, and there are many very naïve places. But Sun Xiang was sure that this fluctuation was alchemy.

The spiritual roots of Lishui Zhi are deeply rooted in the leylines, and even in the last era, it would take a lot of effort for cultivators to enter the leylines. The leyline is the trajectory of the earth's spiritual energy, and it is buried tens of thousands of meters deep underground, which is not a depth that can be reached by digging a pit.

And it's not all quiet underground. There are many dangerous creatures lurking in it. Rash exploration, ten deaths.

But there are also ways to cheat. Because the leyline flow is not permanently hidden underground, when the leyline aura is too strong, it will occasionally emerge from the ground.

The exit is usually a volcanic crater or a very deep hot spring that connects to a crack in the ground. The power of the earth is vented through these outlets, spewing out the power of nature into the world.

Through these places, cultivators can easily reach the depths of the earth's leylines. At first, the head of Sun Da also thought that Su Lei had mastered such an entrance. But he had been exploring for a long time, but he had not sensed such a boundary near the Thousand Feet.

It wasn't until he just felt the fluctuations of the alchemy that he suddenly realized that it was such an ingenious method.

Alchemy is a special method of retreat that practitioners use to move through metal. The battle of this retreat is of little significance, because the battle of the previous era will not be fought on the steel plate. Dirt, wood, and even fog are all useful escape techniques. Alchemy, on the other hand, is actually a means of prospecting, and many practitioners who specialize in refining weapons will be proficient in this method.

Because alchemy can also travel through the veins of metal. Using this technique, practitioners can search for the finest ore hidden deep within the veins, thus saving them the trouble of digging caves.

Su Lei came up with the ingenuity to use this method to enter the extremely deep underground.

Then that makes sense. The Xuanjin Mine was originally a precious spiritual material formed by the rise of the golden sharp qi of the veins in the depths of the earth and the fusion of the true fire of the sun on the ground. Although the gold in that cave has been mined, its veins have not been broken.

As long as you use the golden magic to follow the golden sharp qi, you can enter the leylines below the thousand feet, no wonder so many people can't find this entrance.

So the question is, how did Qianjiao master the magic of gold? All the types of magic techniques today come from the head of Sun Da, and he is very sure that he has never taught this magical power.

Coupled with the fluctuations he had just felt, he was sure that the Imperial Alchemy used by Su Lei was only a half-finished product, and it was by no means as mellow and concise as Sun Xiang had mastered. Therefore, it is certain that there are people in Thousand Kicks City who have created their own alchemy type.

Su Lei: No way! The head of Sun Da categorically denied this speculation. The so-called phase is born from the heart, and Su Lei's scummy and exaggerated physiognomy is by no means the type that can create his own magical powers. He lacked the necessary focus.

All in all, Sun Xiang figured out the method, and the rest was not a problem. He instructed Guan Jie to leave first, break away from the main army himself, and march deeper into the valley.

He didn't try to infiltrate the locked cave, and although the guarding cultivators were useless to Sun Xiang, there was no need. The golden qi of the leylines has risen, and more than one vein has definitely been formed.

Sure enough, at the foot of the mountain in the opposite direction of the mine, he found another place where the aura of Jin Rui was strong. The rocks here have a yellowish tinge. Over time, these rocks will be scorched by the true fire of the sun and will coalesce into expensive gold one night. Only now, they're still worthless ordinary rocks.

Sun Xiang pressed his hand on the surface of the rock, and his palm was fictitious. Without any fancy sound and light effects, his figure vanished in the blink of an eye.

On the other side, Cai Qingjia knelt on the ground weakly, and finally recovered from the discomfort of Yujin. The alchemy technique used by Su Lei was not perfect, and as he traveled through the veins, he would feel violent vibrations and dizziness. Su Lei is better, after all, he is a driver.

The two of them traveled with gold, and the speed was extremely fast. In just a few minutes, it has gone more than ten kilometers underground. In the process of traveling, Cai Qingjia witnessed countless bizarre scenes, including upside-down white hollows, huge ice that looked cold to the bone, and even huge monsters that were dark and indescribable. But most of them are glimpses of auspicious feathers, like high-speed silhouettes. It seems that some impressions have long since disappeared when I look at them again.

The underground world is not a peaceful resting place, and it is sometimes even more lively than the surface. The reason why these strange creatures don't come to the ground to make waves is simply because the true fire of the sun is an intolerable poison to them.

And what they rely on for their survival is the abundant aura in the vast leylines.

Maybe it can't be called Reiki anymore.

Cai Qingjia got rid of his vertigo and was surprised to find himself in a wide underground cavern. There is no sunlight here, but it is not dim. The milky white soft light illuminates the surrounding world like the ground world at dawn. The air here is clean, but it doesn't seem to have oxygen in it. Here, the practitioner has to operate the inner breath so that he does not suffocate.

Surrounded by strange and magnificent black crystals, it is like being in a jungle of crystals. A milky white river passes silently through the place beneath his feet, and disappears into a bottomless dark abyss. Cai Qingjia noticed that the milky white light that filled the surroundings came from this river.

"What is this?"

The milky white liquid in the river aroused Cai Qingjia's great interest, and her hands even trembled slightly to touch it. Because she truly felt the outrageously abundant pure spiritual power in this liquid, it was really a great temptation for a cultivator.

The corners of Su Lei's mouth secretly crossed a mocking smile. He stopped Cai Qingjia's reckless moves.

"This is the leyline, the liquid river formed by the extreme condensation of spiritual energy. But don't touch it, the meridians and dantian will be burst. ”

Cai Qingjia trembled and retracted his hand. She hesitated for a moment, then decided to trust Suray on the matter. The reason is very simple, if this liquid can be absorbed and utilized by humans, I am afraid that Su Lei will already be an invincible existence.

"Follow me. ”

Su Lei led the way in front, and Cai Qingjia glanced at the leyline river regretfully, and reluctantly left. She followed Suray for a long time through the jungle of black crystals. It's like a labyrinth, with transparent crystals reflected from various angles, making it impossible to distinguish between things.

Su Lei walked through such a labyrinth with ease, and Cai Qingjia was puzzled at first, but later noticed that many crystals were marked with words. She pretended to stumble and approached a mark.

It's a stick figure cat with its paws pointing to the right, and it looks cute. Cai Qingjia glanced at Su Lei without a trace, this was definitely not his handiwork.
