(Three more more.) ）

After decades of perseverance, the boy became a young man, and his cultivation also reached the foundation building period, and he was recognized by everyone.

He settled down on an ordinary hill and cattle herding mountain in Xingchang County, and began to study what he had learned, write books and lectures, and began to treat diseases and save people.

If the people he saved were poor people, he did not take money, but asked them to plant an almond tree on the mountain.

However, the good times didn't last long, but in half a year, he found that the Tsukidan he had refined was actually poisonous. Some practitioners who have taken Tsukidan have experienced severe erysipelas.

If it is light, the true element is unstable, and it is difficult to continue cultivation; if it is a little heavier, the meridians will be blocked; and even more seriously, even the meridians and acupuncture points will begin to shrink, and there will be many people who have gone mad.

The crowd condemned.

In order to appease the anger of the public, he killed himself three times in accordance with the rules of the rivers and lakes. It's the so-called three cuts and six holes.

Later, after repeated research, it was discovered that the problem was in the alchemy furnace.

More precisely, it is the material of the alchemy furnace.

The inferior alchemy furnace contaminated the elixir.

He had to buy expensive, alchemy-specific spiritual materials. But they are shy in their pockets and can't afford to buy expensive red copper, pure gold, etc., so they can only look for relatively cheap dark iron.

It's just that the high-purity, non-toxic Xuaniron, which is suitable for making alchemy furnaces, has always been controlled by the East. A pound of 99% pure black iron, a merchant from the East, offers a sky-high price of 100 to 500 high-grade spirit stones!"

"Poof...... Five hundred high-grade spirit stones!" Zhang Hao was dumbfounded. Five hundred high-grade spirit stones are five million lower-grade spirit stones! That's a thousand tons of spirit stones, which can be piled up into a small mountain!

Zhou Jue sighed leisurely, "This kind of dark iron for alchemy is said to come from the Kunlun Continent, and even the country of Canglan and Taihua cannot produce it.

The cheapest one hundred high-grade spirit stones, the best five hundred. Fixed price, no room for bargaining. ”

After listening to Zhou Jue's little story, Zhang Hao was very distressed. He suddenly found that just now he said that he could produce more than ten tons of special dark iron for alchemy a month, which was still a bit shocking.

Obviously I've been very careful~~~

However, Zhou Jue is still telling his story: "If you want to refine the smallest and simplest alchemy furnace, you also need ten catties of dark iron." Then it will take a thousand high-grade spirit stones.

He couldn't take it out.

At this time, the surrounding people came, and some of them sent three or five lower-grade spirit stones, and some sent more than a dozen lower-grade spirit stones. Each person didn't give much, but it only took three days to gather the wealth of more than a thousand high-grade spirit stones.

After that, he spent a month building a new alchemy furnace. Since then, there have been no more erysipelas incidents.

But the good times didn't last long, and there was a problem with the alchemy furnace.

Alchemy for a long time, roasting for a long time, the alchemy furnace is no longer pure. It has to be replaced. ”

"Wait, I heard that a good alchemy furnace can be used all the time, right?" Zhang Hao interrupted Zhou Bo's story.

"It's an alchemy furnace made of pure gold. Generally speaking, an alchemy furnace made of dark iron can be used for one year, but not more than three years. Made of red copper, it can be used for more than ten years. Made of Mithril, it can be used for about fifty years. Made of pure gold, it can be passed on. ”

"I see. Thank you. ”

Zhou Jue nodded and continued to tell the story: "Fortunately, at this time, he already had fame and some savings, and he began to study abroad. He communicated with all parties, and even spared no expense to borrow books from the Jiuyang Sect and various families.

He has traveled all over the country of Qixia, he has been to the country of Canglan in the East, the country of Taihua, and even more eastern countries.

After traveling for more than 50 years, until the peak of the Jindan period returned to Fangniu Mountain.

It was summer, and at this time, the cattle herding mountain had already become a forest of apricot trees, and the mountains were full of apricot fragrance, and many children were playing in the forest.

For more than 50 years, the surrounding people used the money from selling apricots to build a Taoist temple that began to take shape.

Xinglintang.

From that moment on, there was an apricot forest hall in Fangniu Mountain, and an acopricot forest hall in the country of Qixia.

He is his father, Zhou Shuhai.

From that day on, my father settled in Fangniu Mountain, and a few years later married a female disciple of the Jiuyang Sect. Until today, a hundred years have passed in a hurry.

Now, for anyone who is interested in alchemy, my father will provide free support.

Every year, many people come to Xinglintang, some from the West, and some from the East.

There are hundreds of alchemy masters living in Xinglin Hall. This is already the largest alchemy holy place in the country of Qixia and even in the entire West.

However, my father knows that 'there are many celebrities in front of him', so he deliberately keeps a low profile, so that he can also refine the pill with peace of mind. ”

Zhang Hao listened to it and was in awe. Although I haven't seen this Zhou Shuhai yet, I already have a yearning for it.

The reason why the world can continue to progress is because there are always people who are quietly giving and thinking about the whole group.

With a faint sigh, Zhou Jue turned his head to look at Zhang Hao: "Brother Shi, do you know that if you refine Pei Yuan Dan, even if you use the most ordinary alchemy furnace, according to 20 furnaces per day, an average of 100 pills per furnace, and 1,000 days in three years, the cost of each Pei Yuan Dan alchemy furnace will be evenly apportioned, and there will be 5 low-grade spirit stones."

If you include the failure rate, the spirit stones that give birth to flames, medicinal materials, etc., the cost of one Peiyuan Pill is as high as more than 15 spirit stones. If you include the alchemist's income and consumption, the cost price is as high as 16 spirit stones!"

Zhang Hao exclaimed: "I heard that the price of Pei Yuan Dan in the Eastern Kingdoms is even only three or two spirit stones. ”

"Yes, there's even a spirit stone. Zhou Jue's face was angry, "But we can't help it, we lack medicinal materials, we don't have special dark iron for alchemy, everything can only be purchased from the east, and the country of Canglan and the country of Taihua have monopolized the trade routes."

We can only stretch our necks and let others slaughter!"

Zhang Hao didn't answer immediately, but thought for a while before asking, "How much special Xuanxian for alchemy does Xinglin Hall need in a year?"

"If the purity is 99.1% to 99.3%, 500 ordinary Dan furnaces are required every year. Dan furnaces are large and small, almost 2,500 stones. Close to 10 tons.

If the purity is between 99.3% and 99.5%, it takes 100 Dan furnaces, which is almost 2 tons.

If the purity is higher than 99.5%, it should be more than 20 pieces and 0.4 tons.

Every year to purchase special dark iron for alchemy, we will spend more than 3 million high-grade spirit stones.

If you count the medicinal materials, just here in Xinglin Hall, the annual outflow of high-grade spirit stones is as high as 10 million.

Today, Xingchang County already has sixty percent of the spiritual stone deposits...... It has been depleted, and most of the rest is overexploited.

It is expected that in a hundred years at most, we will have no spirit stones available!

At that time, the Western countries may no longer be able to cultivate a cultivator above the foundation building period!"

Zhang Hao was shocked by this astronomical number. Compared to these, the achievements of the Zhang family now are really insignificant.

After a while, Zhang Hao asked, "How much special dark iron for alchemy is needed every year in the whole country, and even in the entire Western countries?"
