This feeling is not the first time, it has appeared when it is inextricably wound before, but how can she feel like this? Tan Shuangshuang thought a little distractedly.

In his mind, the goddess named Changge and Shuangshuang said something again, and then Shuangshuang began to learn the formation with the goddess called Changge.

Some incomparably complex formation knowledge was told by Changge, and it became easy to understand, Tan Shuangshuang couldn't help but learn with the Shuangshuang goddess with the same name as her, and soon immersed herself in the world of formation.

Changge is really a teacher who is very good at lecturing, just like Ling Wuchen, so that Tan Shuangshuang, who has always had a headache and is difficult to understand the formation, is addicted to it, and unconsciously memorizes these originally boring knowledge.

The time of learning passed quickly, and when the picture of Changge teaching Shuangshuang disappeared in her mind, Tan Shuangshuang, who came back to her senses, looked at the phantom array around her and found that this mysterious phantom array that originally made her helpless was really pediatric.

Before, Tan Shuangshuang looked at the phantom array and had nowhere to start, but now at a glance, she found that this phantom array was simply full of flaws, with the formation knowledge in her mind now, she came up with countless ways to easily crack this phantom array in an instant.

However, Tan Shuangshuang didn't really break this phantom array, if the phantom array was broken, the fool would know that there was a problem, and she didn't come to attack the other party, she just quietly probed the news to determine the true and false size of the spirit stone vein, as for the fight, she had to wait until the people from the sect came.

Tan Shuangshuang easily walked out along the flaws in the phantom array, as soon as he walked out of the phantom array, the entrance of the spirit stone vein he had seen before appeared again, this entrance was low, and there were weeds outside the cave to cover it, and people had to climb in half-lying on their stomachs to enter.

Such a small cave, if you don't pay attention, it will be regarded as a nest of some animal, and you can't imagine that it is actually a spirit stone vein inside, which shows that the secrecy of this entrance is excellent.

Looking at this entrance, Tan Shuangshuang didn't dare to drill directly into it, if there was a guard inside, she wouldn't ask someone to chop it up, Tan Shuangshuang cautiously used spiritual power to carefully probe and perceive it, and found that there were indeed people guarding the entrance inside, and it was impossible to get into it silently.

Tan Shuangshuang thought about it, and did not venture in, but decided to stay at the door of this place and wait for the opportunity first, she didn't believe that if this place was a spirit stone vein, the other party would not send spirit stones out, would not come out to buy food, and the people outside would not come to replace the people inside.

Tan Shuangshuang waited patiently for a few days, and sure enough, the people who came to replace them were all wearing black clothes and masks, and they were dressed tightly, they couldn't tell who they were, and they couldn't even tell the difference between men and women, and the meaning of hiding their identities was obvious.

Although these people wrapped themselves very tightly, Tan Shuangshuang still had a bad conjecture from their walking posture, no matter how people hid it, some habits still couldn't be changed.

These people swagger when they walk, even if they can cover it, they can't stop the regular movements between their gestures, which is the posture that can only be seen in the army after a long period of training, these people are actually from military background!

Tan Shuangshuang's mood sank, if there was official intervention in this matter, it would be troublesome, everyone had selfish intentions, if it was the lord of a city who wanted to swallow this spirit stone vein, it was no wonder that the small family was destroyed so quickly but it did not attract any official attention at all, and no one came to investigate.

Tan Shuangshuang frowned, took advantage of these people walking through the phantom array, quickly sneaked into the phantom array, and used a flaw in the phantom array as a cover, quietly put down the last person of this group, changed into this person's clothes and mask, and quietly followed.

This time, Tan Shuangshuang smoothly followed these people into the low mine, and no one found it at all, only to find that there was a cave inside, and the dark cave was lit up by the fluorite dotted with daylight, and it was not stuffy at all, obviously there were enough ventilation holes.

The huge cave is connected to the mine road in all directions, and there are many people stationed in the cave, all of whom are wearing masks and robes, and none of them are talking, although there are many people, there is no sound, so many people gather together silently, and the atmosphere is inexplicably a little weird and terrifying.

In the corner of the cave, there was a stone table, and behind the table sat a masked man, who was wearing a mask, but instead of a black robe, he was wearing a turquoise robe.

When Tan Shuangshuang followed the crowd in, he happened to see a group of people dressed in the same mask and black robes as here coming out of the mine, these people walked to the stone table in an orderly manner, and then took out storage bags and put them in front of the masked man.

After the masked man inspected, he would put away the storage bags, and when he put away the storage bags, the masked man would place a storage bag on the table plus a row of low-grade spirit stones, the number of spirit stones ranged from a dozen to dozens of pieces, and the black-robed masked man who put down the storage bag would put these spirit stones into the storage bag and take them away.

The value of a piece of spirit stone is sky-high, the money traded by ordinary people is mainly silver coins, copper coins and a small amount of gold coins, and the money traded by cultivators is mainly gold coins and spirit beads, and it is rare to use spirit stones.

The reason is also simple, 10,000 spirit beads can only be exchanged for a low-grade spirit stone, and the purchasing power of spirit beads is extremely strong, except for a few places where money needs to be spent, cultivators can easily use so much money.

Spirit stones are more commonly used for cultivating or driving various alchemy refining items, such as flying magic weapons and the like.

The spirit bead that the masked man placed on the stone table was obviously the reward of the person who handed over the storage bag, and the reward was so generous that although there was still silence in the cave, Tan Shuangshuang still felt a wave of joy and excitement permeating the cave.

Then the group of people came one by one, handed over the storage bags, and then got their own payment, and when they had received the payment, they lined up, and crawled out of the entrance on their stomachs silently, leaving quietly without hearing their footsteps.

After those people left, the team followed by Tan Shuangshuang quietly divided into five squads and entered the mine road with five forks.

"You have also seen that the last wave of people made a lot of money and left, we work harder, but we can't earn less than them, brothers, work hard here, work here for a few days, and when you go out, you can do whatever you want if you have money in your hands."
