The spirit stone veins are so hard that they can't be knocked down with an iron pickaxe alone.

Only with the help of spiritual power can the monk use a sharp weapon to cut off the raw ore bit by bit.

Therefore, mortals are not up to the job of mining.

However, there were only one or two hundred monks in the Black City, and less than half of them were willing to work in the mines, so there was always a shortage of manpower in the mines.

As a monk Su Xing, he didn't have much trouble getting in.

According to the regulations of the Castle Lord's Mansion.

Wages were paid in the caves in the form of more work and more pay, and each time the monk dug up a piece of raw ore, his salary would rise a little more that month.

If this is changed to the statement before the Su Xing crossing, it is the piecework system.

Although the piecework system is hard, most of the monks in the mine are at the end of their lives and come here to work to buy life-saving medicines.

As a result, they hardly ever go into slacking off at work.

In order to buy life pills to continue their lives, these people will work from morning until dark, living a life of cattle and horses all day long....

They dream of raising their salaries.

Or, the price of longevity drugs can be lowered.

In this way, Su Xing, as a life-saving medicine dealer, is tantamount to a savior for these people.

In the mine, Su Xing is the god of medicine, because his medicine is cheap enough.

The spirit stones of the monks are all earned by hard work.

Since Su Xing had a cheaper life pill in his hand, why didn't he buy him?

…

During the first three days of entering the mine, Su Xing'an kept to himself, and everything was prioritized to familiarize himself with the environment and build good relationships with others.

But on the fourth day, Su Xing began to have seizures.

In the mines.

Su Xing looked around and saw that not many people noticed him, so he carefully approached the target he had already selected.

Su Xing lowered his voice, like a thief: "Fellow Daoist, do you want a life pill?" Sell you cheaply. ”

"How much?"

As soon as he heard that Su Xing was selling the life pill in his hand, the monk immediately became interested, and he did not have any doubts in his heart.

Because the drug dealers in the black city are far more than Su Xing....

Corruption has existed since ancient times, and it cannot be eradicated.

This black city is no exception.

Some high-ranking monks working in the City Lord's Mansion, as well as high-ranking celestials, will have more or less access to life-saving pills.

The most critical thing is.

Because of their noble status, even if these people are caught doing bad things, there will be no serious consequences.

At most, he was transferred to another position.

Then it is logical for these people to take some of the life pills issued by Heavenly Court and put them in their pockets.

The celestials and the high-ranking monks took it, but because of their own status, it was impossible for them to sell it themselves.

As a result, there are countless 'life medicine dealers' like Su Xing in the black city.

They act unscrupulously.

Even if a steward bumps into it, he will choose to turn a blind eye for fear of offending the boss behind him.

The life pill sold by the City Lord's Mansion is one of the Five Spirit Stones, so in order to compete with the City Lord's Mansion, the price on the black market is generally below the Four Spirit Stones.

Su Xing thought for a moment and said conservatively: "One of the four spirit stones, or?" ”

"Yes."

The monks at the bottom could not afford to buy storage bags.

After the monk escaped from his arms and handed them over to Su Xing, he couldn't help but ask, "Fellow Daoist, which one are you selling for here?" ”

Apparently.

This low-level monk also wants to help the 'big guy' behind Su Xing.

And Su Xing had expected this to happen.

He said with a mysterious face: "The man behind me said that he didn't want to expose himself.... But if you really want to sell, you can get it from me. ”

Is there still such an operation?

Hearing what Su Xing said, the monk showed a confused expression, obviously shocked by the sales concept far beyond this era.

After hesitating for a moment, he felt that this matter was feasible: "How do you do it?" ”

"It's easy."

Su Xing replied: "You take the life pill from me, I will give you one of the three spirit stones, and you will sell the four spirit stones to others, won't you have to make money?" ”

"Indeed!"

The monk was quick-witted.

Su Xing's plan, he just thought about it a little, and he felt that it was feasible.

But now there is still a problem that has not been solved: "But, brother, I really don't have any spirit stones now, can you give me a few life pills first, and then return the spirit stones to you when I sell them?" ”

"Of course you can."

Su Xing said with a hint of threat in his tone, and said as a matter of course: "The entire Black City is so big, are you still afraid that you won't be able to escape?" ”

The monk said sincerely, "Yes, I can go even if I want to." ”

The two talked to Jian, and Su Xing took out four life pills from the storage bag and handed them to the other party.

"Sell out at any time, you can come to me at any time."

"Okay!"

…

After opening up the market, Su Xing was in a good mood.

After digging a few pieces of raw ore in the mine, he hid in a corner and sat cross-legged, silently running the exercises in his body.

Unlike other monks, Su Xing fought for spirit stones by selling life-saving pills.

He didn't need to mine in this cave at all.

Instead of being a cow and a horse here, it is better to seize the time to cultivate in order to improve your cultivation.

After staying up to the end of work, Su Xing handed over the raw ore to the steward, and after receiving a 'spiritual light talisman', he returned to his foothold.

There was no sunlight in the city, and the climate was hot, so it was impossible to grow crops normally.

But there is no shortage of food in the Black City.

This is because there is a food called 'crystal mushrooms'.

'Crystal Mushroom' is a very fast-growing plant that can only be grown in the dark, and its appearance is like a mushroom.

They do not need to be tended, fertilized or watered, and they can grow a large patch on their own.

The only caveat is that the mushroom must not see any sunlight until it is fully ripe, otherwise it will burrow into the ground and disappear.

'Crystal mushrooms' are extremely productive and can be sown everywhere.

The nearly 100,000 people in the black city are almost all fed by this mushroom.

But because he disliked the bad taste of this 'crystal mushroom', Su Xing had been eating the dry food he had brought with him almost all the time in the past few days when he came to Heicheng....

…

And so it went on for more than two months.

Through the word of mouth of the monks in the cave, Su Xing's life medicine business is getting bigger and bigger.

Not only did he develop two life pill agents, but his own cultivation was also successfully promoted to the tenth level of qi cultivation after absorbing a large number of 'black silk threads'.

He only needs to take a further step in his cultivation before he can be promoted to a foundation building monk.

Meanwhile.

After getting acquainted with the monks in the cave, Su Xing also discovered a secret.

When the raw ore is cut, it will more or less emit some spiritual power.

These spiritual powers can be absorbed by monks to improve their cultivation, or they can be stored in 'spiritual energy bags' and sold to others in exchange for spiritual stones.

In short, these escaping spiritual powers can be regarded as the 'wool' in this mine.

With wool, wool pickers naturally came into being.

Some miners who were eager to improve their cultivation simply stopped working hard after discovering this, but repeatedly used the aura to cut the ore veins and continuously absorb the aura that escaped from it.

This includes Su Xing.

And that's not all.

When Su Xing was absorbing a newly born ore vein, he also discovered another strange thing:

While this vein emitted a large amount of spiritual energy, there was also a trace of 'black silk thread' that appeared from it.

But the 'black thread' can only be generated by humans.

So, could it be that there are still living people hidden in this vein?
