Yu Zecheng's gaze was fixed on the price of Xuantie, Xuantie belongs to the most popular material in the immortal cultivation world, and a pound of Xuantie is worth a low-grade spirit stone, which is almost a fixed price, and there will be no major changes.

And Yu Zecheng refined three catties of dark iron, and spent three thousand taels of silver to buy black iron. One catty of dark iron is worth one spirit stone, one spirit stone is worth one hundred taels of gold, and one hundred taels of gold is three thousand taels of silver, in other words, three catties of dark iron are worth nine thousand silver. There is a huge price difference in the middle, and you can buy it from the iron family, without the exploitation of the middlemen, the price of black iron will be cheaper, and the profit will be even greater.

These times, Yu Zecheng has now saved 3,000 taels of silver in his hands, plus the gold seized by the Medicine Picking Gang, the 100 taels of gold obtained by killing Tan Erlang, and the gold obtained from the Heating Gang, after deducting some expenses, now there are a total of 1,000 taels of gold, and the total net worth is 33,000 taels of silver, which can be regarded as a rich family.

If these gold and silver are exchanged for black iron, condensed into dark iron, and then exchanged for spirit stones, and then exchanged for gold and silver with spirit stones, this is simply doubling the money, and the profits are amazing.

His advantage over others is that the Yimu Great Array supports the operation of the Dan Furnace, and refining Xuaniron only takes time and energy, and does not consume True Yuan and Spirit Stones, so there is such a huge price difference in the middle.

Even if you don't exchange it for silver, you will embark on the road of cultivating immortals in the future, gold and silver will not be of much significance to immortal cultivators, looking at Yaxiang's appearance, immortal cultivators will always lack spirit stones, don't plan early now, save more money, so as not to suffer losses in the future.

Thinking of this, Yu Zecheng was immediately happy in his heart, and his heart was not as good as action, he immediately returned to Mangkhut City, found the peak, and asked him to contact the person in power of the Tie family for him, this is not a small transaction, it requires a large amount of black iron.

Gao Feng immediately agreed, replying:

"Helmsman, this is easy to do, Lin Yehong has now become the helmsman, the rudder where he is located is Ironstone City, where there are all iron mines of the Tie family, I will contact him now and definitely solve this matter." ”

Yu Zecheng nodded, even if this matter is arranged, it will take three or four days for the flying pigeon to pass the book back and forth, so just wait for the news.

So Yu Zecheng returned to his cultivation place, and was about to reach the top of the mountain, and Yu Zecheng remembered that he found something wrong when he was looking for the spiritual spring leyline, as if there was a strange aura in this mountain.

Yu Zecheng gritted his teeth, turned around and returned to Mangkhut City, hired a large number of stonemasons in the city, led them to the peak, found the place where the spiritual energy might gather, and ordered these stonemasons to dig down to see what was inside.

This is the benefit of money, under the reward of money, hundreds of people worked hard, and suddenly the place began to excavate, digging down three feet, it was all stone and rock terrain, Yu Zecheng continued to order them to dig, so under the work of these stonemasons, with a hammer and chisel to dig up the stone and rock little by little, straight down three zhang, and finally dug to the location of Yu Zecheng's induction, and sure enough, there was a spiritual object there.

Three zhang below, there is a hollow, this hollow is surrounded by rocks, chiseled the hole and suddenly a stream of spiritual energy spewed out, wait for a while someone to go down to explore, found that there is a spiritual tree in the hollow.

In fact, this hollow was originally a towering tree, I don't know how many tens of thousands of years ago, because of the change of terrain, the landslide was low cracked, trapped in the rock, it was not scorched and carbonized, absorbed the earth's vein aura, and gradually became a spiritual tree, but the volume became smaller and smaller, and it was found that it was only one zhang long and one foot thick.

Everyone ripped off the rope and tied the spirit wood, hey, hey, pulled it out, no wonder the aura of this mountain is compelling, this spirit wood is moistened by the spiritual spring vein, and at the same time it is fed back to this mountain, so there is such momentum on this.

Yu Zecheng is a treasure of joy, but unfortunately he doesn't know how to apply this wood, so he has to bring the spirit wood to the spirit spring and plant him in the spring, so that the spirit in his big array suddenly doubles and condenses, which can be regarded as a good effect.

In this place full of spiritual energy, Yu Zecheng began to cultivate, and his cultivation speed was suddenly three points faster than in Mangkhut. It's a pity that all my exercises are hanging in a bottleneck, this is not something that can be increased by penance, only by relying on accumulation and epiphany, and going with the flow.

Gao Feng quickly sent back the information, and Lin Yehong over there completely understood the contact, and only received five taels of silver for a hundred catties of black iron, and the amount was very large, so that Yu Zecheng could negotiate in the past, and suddenly Yu Zecheng was overjoyed, returned to the rudder, and took Du Youzi and Fu Qiang and four disciples to go to Iron and Stone City.

Iron Stone City is located in the north of Linhai City 100 miles, and Mangkhut is 150 miles away from Iron Stone City. In fact, it is also the outer area of the 100,000 Great Mountain, with hilly terrain, rich underground iron mines, and countless iron and stone resources.

It can be said that hundreds of mining areas large and small are monopolized by the Tie family, and thousands of catties of black iron are refined in the steel furnace every day. With such a channel for money, Ironstone City is also very prosperous.

It is now the golden autumn and October, and the crops have been harvested, Yu Zecheng took his disciples and rode horses all the way to Iron and Stone City.

Now there is a hint of coolness, and the leaves are starting to fall, but the scenery at this time is the time to pleasing the eyes, and the mountain flowers are full of October days when you climb high to enjoy the flowers.

Although Yu Zecheng and they were not good horses, they could not reach the speed of traveling 1,000 miles and 800 in the night, but they were a hundred miles away, and they arrived in one day, and in the afternoon, they came to Ironstone City.

Before entering the city, I saw the sky full of smoke, which were all large and small steel furnaces refining steel, making the sky gloomy, as if the sky was full of dark clouds.

Lin Yehong was already waiting at the city gate, for what Yu Zecheng wanted, Lin Yehong made great efforts, went through the relationship between all parties, and finally got the reply of the iron fist of the iron family boss in Tieshi City, and sold the black iron to Yu Zecheng at the lowest price.

The reason why Lin Yehong is like this, there is a meaning of repaying Yu Zecheng, he was entrusted by Cui Renxiong to go undercover under Yu Zecheng to investigate the matter of the mountain tiger rudder, although neither of them said anything, as if it didn't happen, in the end, he was a little embarrassed to face Yu Zecheng, and now he is trying his best to compensate.

When the two met, Lin Yehong immediately gave a disciple salute and said:

"Lin Yehong greets the helmsman. ”

Yu Zecheng hurriedly stopped and said:

"Brother Lin, didn't you kill me? You are also the helmsman now, you are older than me, you should be ......"

Lin Yehong interrupted Yu Zecheng's speech and said:

"Anyway, I'm your disciple, if I hadn't survived the difficulties with you, how could I have today, I can't stand you for the previous things, please forgive me." ”

Yu Zecheng said with a smile:

"What's the matter? don't mention the past, you can help me take care of it so that I can save some money, then it's better than anything else. ”

The two talked enthusiastically, everyone said and I laughed, and the guests and hosts entered the city in harmony. This time to welcome Yu Zecheng, Lin Yehong really made a big investment, and took the best Qinglou Xiaoxiang Building in Tieshi City alone, entered the landlord, and hundreds of girls waited here, all serving Yu Zecheng and others, it can be said that Yu Zecheng spared no effort to welcome him.

Everyone is on the banquet, you respect me, I respect you, everyone is not happy, Lin Yehong is sacrificing his life to accompany the gentleman, he vomited twice outside or toasted, and finally the guests and hosts were all drunk, and this is the end of the reception.

Early the next morning, Lin Yehong took Yu Zecheng to meet the iron family boss Iron Fist, and the two sides reached a consensus that Yu Zecheng bought 100 catties of black iron at the price of 5 taels of silver, and bought 600,000 catties of black iron here, a total of 30,000 taels of silver and 1,000 taels of gold.

Yu Zecheng went home when he came to collect the gold, and handed over the surname to Iron Fist once, so it can be said that this time he put all his net worth on this.

These transactions made Iron Fist very satisfied, although the price was low, but there were enough reserves of one million catties in the warehouse of the Black Iron Iron Family, and half of it was sold at once this time, and it would definitely be rewarded by the Council of Elders at the end of the year.

A stand of black iron is exactly 15,000 catties, and Yu Zecheng has three Qiankun bags in his hand, one large and two small, which can be shipped 150,000 catties at a time, and it takes about four times to take all these black irons away.

Although the Qiankun bag can completely fit the black iron, the weight is still reflected on the Qiankun bag, and the three bags weigh a thousand catties, that is, Yu Zecheng's physical strength has increased greatly through cultivation now, otherwise he will definitely not be able to hold these three bags.

In this way, Yu Zecheng began to put black iron into the Qiankun bag, which was enough to be busy and a day, before it was over, at this time it was late, and he would have to walk at night when he went back, so it was better to spend another night here, and talk about it tomorrow.
