Because of the secret market, there are really a lot of good things here, such as the purple gold that Wei Tianchong needs, and there are several stalls here that are sold, and the prices are cheap. A fist-sized piece of purple gold can be sold for more than two or three thousand spirit money in Wenxin China, but it may not be able to be bought. And here, the price is only 1,800 yuan. If you can bargain, you can buy it for 800 to 1,020.

This is mainly because precious resources like Zijin are not sold to the outside world, but they are controlled by the Dadao faction, which controls exports, not to mention the limited quantity, and the price is still high, which naturally causes the price to remain high. And to put it bluntly, this secret market is a smuggling market and a black goods market in the realm of cultivating immortals, and without so many intermediate links, the price will naturally drop significantly.

In the final analysis, Zijin is only refined from the ore produced underground, and there is almost no cost in itself, and eight hundred spirit money is already a huge profit.

According to the rules of the Evil Jiao Gang, each item of goods sold here must be charged 20% of the selling price. This commission is not low, but even so, it is still a very profitable business.

Wei Tianchong calculated the account, he brought a total of 10,000 yuan this time, if all of it is used to buy materials, and then bring it back to sell, the price can be at least doubled, and the profit is equivalent to 100%.

This made him excited, in the end, he was born in a merchant family, Wei Tianchong seemed to have found a way to make money, and grabbed Tang Zheng and said: "This business is worth doing, Tang Zheng, this is the benefit of the Ben and the Profit." If this is a hundred thousand dollars of spiritual money, wouldn't we have made it?"

Tang Zheng looked at him coldly: "Do you have a million spirit money?"

Wei Tianchong was immediately dumbfounded, not to mention that he didn't have it, even Wei Mansion didn't have it.

Besides, with so much money, there may not be such a big market.

"In addition, this secret market is only once a year, and the risks along the way are also great, and it takes more manpower and time to buy and sell goods. You and I have to cultivate, and we don't have the energy to ask at all. If you really have to worry about this kind of thing, if you have earned the money, what should you do with your cultivation? Have you ever heard of a great power who made a fortune by doing business? Or do you think that as long as you find a way to make a fortune, you can sit there and enjoy the success?" Tang Zheng added.

Wei Tianchong scratched his head: "Aren't I also worried about money." ”

Even young masters, there are times when they worry about money.

After Wei Tianchong became the true heir, the money given to him by the Wei Mansion did not increase, but actually decreased.

There is no way, the resources spent on cultivating immortals are too great, and even the big families cannot support such a huge consumption for many years, so they usually provide a lot of resources for their children in the early stage to lay the foundation, and they must reduce their investment in the later stage.

Generally speaking, when students reach the Linghai level and have a large number of trial tasks, they must make money on their own, and at this time, half of the family's investment and their own money.

When the student enters the world, the family investment will be further reduced.

When you go to the next level, get out of the peak or enter the heart of heaven, it's time for the cultivator to give back to the family.

Because of this, don't look at Wei Tianchong who brought 10,000 yuan over this time, in fact, only 5,000 of the 10,000 money was given by Wei Fu, and the remaining 5,000 was saved by himself in the past two years.

Because it is a passer, and he is a cultivator himself, he has mustard seed bags with him, and the safety and transportation costs are extremely low, so he can have these profits. And strictly speaking, this is not a profit, it is just a saving of expenses, and if it wants to become a profit, you have to continue to spend time selling it after returning to China.

For example, for those caravans, 100% of the profit is already good if it deducts a lot of manpower and material resources and possible risk losses.

There are unlucky ones who have been robbed several times in a row, and it is difficult to say that they are bankrupt.

But having said that, Tang Zheng still said: "We can't do it, Wei Fu can still do it." When you go back, you can tell your wife about the situation here, and there should be no problem for the Wei Mansion to do the business. ”

"That's a good idea. "Samurai also supports it.

To be able to open up an extra source of wealth for the Wei Mansion is to earn more cultivation resources for yourself.

During the conversation, the three of them did not forget their business, Wei Tianchong had already bought a piece of purple gold and was looking for other materials.

Tang Zheng is also walking around, looking for what he needs.

As he was walking, Tang Zheng saw an item on a stall not far away.

It was a piece of black wood, about a foot long, round throughout, with red lines wrapped around it.

Seeing this thing, Tang Zheng walked over and said, "Can I pick it up and take a look?"

The person who set up the stall was a middle-aged man, and when he heard this, he replied in a thick voice: "This is a thousand-year-old blood-patterned wood heart, worth 10,000 yuan, and ten pieces of spirit jade are pressed, whatever you want." ”

"I use this as collateral. Tang Zai took out two pieces of soft fragrant jade and put them on the stage. The middle-aged man saw that it was soft fragrant jade, and his eyes immediately lit up.

Tang Zheng had already picked up the wooden heart and looked at it carefully.

Blood-streaked wood is a good material for cultivating the realm, whether it is making puppets, arranging arrays, or even refining weapons.

It is not easy to get goods for a thousand years, so Tang Zheng didn't take the word "millennium" to heart, thinking that it would be good to have a hundred years. But with the blood pattern wood in hand, Tang Zheng found that this middle-aged man was really not blowing.

Blood-streaked wood is an extremely heavy piece of wood, and the longer it ages, the heavier it becomes. This small piece of blood-veined wood is at least a hundred catties in his hand, but I am afraid that it is really thousands of years, and I don't know where he got it.

If this is the case, 10,000 yuan is really not expensive, but because of this, Tang Zheng is suspicious in his heart.

Tang Zheng looked more closely, and finally found the problem.

This blood-streaked wood heart looks like a whole, but if you look closely, you can see that there are faint cracks.

This means that it is very likely that it has been disemboweled, but the blood-streaked wood has the ability to heal itself, and gradually makes up for the break, leaving only a few gaps.

In other words, this piece of blood-streaked wood was faked, and most likely it was shoehorned with metal to gain weight. This counterfeiter is also careful, using real blood-patterned wood to fake, just to increase the number of years, and the cost is not low, even the metal used to gain weight is also at the level of spiritual materials. If it weren't for Tang Zhengjing's insight, it would not be easy to find.

"It's a pity......" Tang Zheng sighed and whispered, "In order to create a fake thousand-year-old blood-patterned wooden heart, a real blood-patterned wooden heart was ruined." ”

"What nonsense are you talking about?" The middle-aged man changed color when he heard this, and glared at Tang Zheng angrily.

Tang Zao just shook his head and put it down, and was about to get his things back, when the middle-aged man had already pressed on the back of Tang Zao's hand: "Boy, if you don't buy it, don't buy it, what does it mean to slander it? If you don't make it clear today, don't want to take away the collateral!"

"What's the matter, do you fancy my baby?" Tang Zai smiled. He leaned over and whispered to the middle-aged man, "While there are not many people now, everyone will go their own way." If it really makes trouble, this business of finding fools will not be easy to do. ”

The middle-aged man laughed, "You're scaring me? Let me tell you, if you don't explain it to Lao Tzu today, I really can't let you go. ”

Tang Zheng sighed.

If he wants to prove that the other party's blood-veined wood is fake, it is very simple, just pick it up and smash it, but this is equivalent to directly smashing the other party's rice bowl, after all, the cost and effort of this fake wood is also a lot.

Cutting off people's wealth is like killing his parents, he doesn't want to do much, so he picks up the blood-streaked wood again. I wanted to pretend to take a look and admit that I was wrong, but at this moment, my heart suddenly moved, and I looked at the blood-streaked wood with my eyes, and there was a faint feeling of passing through the wood.

He was surprised and delighted in his heart, and stared at the blood-streaked wood with a calm mind, feeling as if he had entered a new world.

The lines of the blood-veined wood continued to amplify in his eyes, gradually filling the entire field of vision, and in its place was a bizarre wood world, every fiber, every pore was enlarged at this moment, just like the world under the microscope, and even continued to penetrate inward.

Finally, the gaze passed through the wooden skin, revealing a black metallic luster, as if the claustrophobic and dark space......

"Hey, you kid is talking!" The middle-aged man's roar still exploded in Tang Zheng's ears.

Tang Zheng could no longer concentrate his attention, and the scenery in front of him changed suddenly, as if he had suddenly returned to the human world from the dark and mysterious world.

Tang Zheng took a long breath and said with a smile: "It turned out to be Black Star Iron, no wonder it is so heavy." ”

As soon as these words came out, the middle-aged man's whole body trembled.

How did he know that the blood-patterned wood of the Dao was filled with Black Star Iron?

Seeing the other party's performance, Tang Zheng knew that he was not wrong.

This made him very excited, he never thought that his insight could be useful in this regard, if this was the case, wouldn't it be more convenient for him to find materials in the future, and he would not have to worry about being deceived or missing out on good things.

Forcibly suppressing the joy in his heart, Tang Zheng looked at the middle-aged man coldly: "Let go!"

The middle-aged man didn't dare to stop Tang Zheng anymore, so he could only watch him retrieve the things.

Tang Zheng already smiled and said: "Three hundred yuan, buy me and shut up, otherwise you won't want to sell this thing again." ”

As he spoke, he vomited brightly, making the cracks on the blood-veined wood more obvious, since this person made a fake and plotted for himself, he didn't mind blackmailing the other party at the same time.

Next, Tang Zheng went all the way around, experimenting everywhere with his newfound insight eye.

He soon discovered that the Eye of Insight did not work for every material, and that the higher the quality of the item, the more difficult it was for the Eye of Insight to penetrate. In addition, some high-level materials are extremely spiritual in themselves, and the eye of insight is not enough to penetrate their interior.

For example, soft fragrant jade is not good.

But in any case, at least seventy percent of the goods in this secret city have no secrets in Tang Zheng's eyes, and he only needs to look at many things at a glance to know the authenticity of good or bad, but unfortunately he has not been able to find any secret treasures.

At this moment, Tang Zheng was turning, and he saw Wei Tian suddenly squeezing over, and beckoned to Tang Zheng: "Tang Zheng, come and see this." ”

I saw Wei Tianchong beckoning to him with a small piece of broken jade in his hand.

Tang Zheng took it and looked at it carefully, and sighed: "This is a fragment of soul jade, where did you find it?"

Soul jade is an extremely rare spiritual material, which can be used to entrust the soul of the gods and cultivate the thoughts of the gods, and it is a treasure in the eyes of high-level cultivators. It's a pity that this piece in Wei Tianchong's hand is only a fragment, and the effect has been greatly lost, otherwise it would not have appeared in this secret city.

"It's the stall over there, it's only eight hundred dollars, not bad, right?" Wei Tianchong said proudly.

"Yes, it's the real thing. Tang Zai exclaimed.

If this thing is placed on the puppet, it can greatly enhance the effect of Wei Tianchong's Black Water Soul Technique.

"Anything else?" Tang Zheng asked.

"Looks like there's another piece. ”

Tang Zai hurriedly walked over, and sure enough, there was still a fragment on the stall, and after checking it, he found that it was also genuine, so Tang Zai asked Wei Tianchong to help him buy it.

Wei Tianchong wondered: "You don't know how to send souls in black water, what do you want it to do?"

"I have my usefulness. Tang Zai said with a smile.

He had planned to buy something that could be used for his soul this trip, but he searched around and didn't find it, but he didn't expect Wei Tianchong to find it.

At this moment, he habitually swept around, and Tang Zheng was about to leave, when he suddenly stopped and looked back, looking at a mirage stone on the stall.

The mirage stone comes from a giant beast in the sea called the mirage, which has the effect of transmitting shadows, and it was this thing that Ji Wuyi used to control the Nine Palaces Lost Heaven Array on Wind Demon Island.

The piece in front of Tang Zheng was much smaller than that on the Wind Demon Island, only about one-fifth of the volume on the Wind Demon Island, and it was also a rough stone, unpolished, and the quality was average.

What really made Tang Zheng care was that when he looked at this mirage stone just now, he habitually used the method of insight, but found that there seemed to be something in this mirage stone.

Tang Zheng simply took the mirage stone in his hand and looked at it carefully, but unfortunately, no matter how much he used his eyesight, he couldn't see the inside clearly, and after his eyes penetrated into the inside, it seemed to be swallowed by something, which surprised Tang Zheng.
