When Song Nian saw the so-called "magic medicine", he became more and more shocked.

This so-called miracle medicine, she actually knows.

It was the famous Gu Ke in the previous life.

Speaking of orthopedics – no, it's Coo-Ke, probably most people don't know very well.

But a beautiful boy who is good at using web search tools will immediately know that it has a famous extract.

Can!

Card!

Cause!

A gift from God, unique from South America.

Song Nian finally understood why she was so familiar with the medicinal properties of this "miracle medicine".

But even greater doubts came to mind.

In a place like the northern steppes, she can understand how opium is grown and grown, but how is it that cocoa, which is a tropical plant, is grown in large quantities here?

Did it come from the south?

Song Nian shook his head slightly, the case of the human-faced sheep corpse had long shown that this magic medicine was transported from the grassland to the mainland, and if it was planted in the south, there was no need to go through such a lot of trouble.

……

Under the affectionate gaze of several archbishops, Song Nian completed a simple purification in front of them.

There's nothing to hide from that. Because laboratory purification and large-scale pharmaceutical industrial production are not the same concept at all.

Song Nian only needs to prove that he understands.

Looking at the small pile of white powder in front of him, the Archbishop of the East twisted a little, put it under his nose and sniffed, frowned: "The quality is indeed good, but this amount is ......."

Song Nian said lightly: "You prepare what I want, this amount is naturally no problem." ”

Several archbishops glanced at each other, and the northern archbishop said lightly: "Everyone, there is no doubt about employing people, not to mention, do you have a better way?" ”

The other three archbishops nodded slightly.

This matter was decided in this way.

But the place where the elixir is refined is not here, but ...... Continue north.

Song Nian was calm in her heart, this was exactly what she wanted.

Since the other party wants to rely on her to manufacture "miracle medicine" on a large scale, there is only one way to bring her to the cultivation base of the miracle medicine and produce it nearby. In this way, the complications of preserving and transporting the miracle medicine are avoided, and the purified miracle medicine is not only more effective, lighter in weight, but also has no problem of corruption and deterioration, which greatly compresses the comprehensive cost.

But to Song Nian's surprise, she went all the way north, arrived at the northernmost part of this grassland, and then ...... Passed through the vast Gobi ......

This made Song Nian even more puzzled.

Could it be that you have to cross the North Pole to reach the other side of the world? If it was really transported from such a long distance, then Song Nian would have to admire the perseverance of the Black Sky Demon God Sect.

However, half a month later, Song Nian crossed the Gobi and arrived at his true destination.

Zheyin Mountain!

Looking at the majestic Zheyin Mountain, Song Nian sighed slightly.

No wonder the Chu River can't find the way to the Yin Mountain no matter what, it turns out that the Yin Mountain is actually behind the grassland, behind the Gobi, over layers of dangers, in order to see the Yin Mountain.

The former Dragon City flying general, who can really step on the Yin Mountain, is really a generation of fierce generals.

Looking at the mountain and running a dead horse, it took a lot of time from looking at the Yin Mountain from a distance to arriving at the Yin Mountain.

When Song Nian arrived at the foot of Zheyin Mountain, he really felt the ferocity of this mountain.

Suddenly, the mountains shook, and the horses around them jumped in shock. Jiuzhou Chinese

But the people who were able to go deep into this place were all the most loyal fanatical believers and core personnel of the Black Sky Demon God Sect, and they had long been surprised by this scene, and they controlled the horses one after another, and soon, the scene quieted down.

Song Nian glanced at the Northern Archbishop suspiciously, and the Archbishop smiled and said, "Don't be afraid, this is the power of the Black Sky Demon God, and it won't hurt you." ”

Hearing such words as the power of the Black Heaven Demon God, the surrounding Black Heaven Demon God disciples knelt down feverishly one by one, and Song Nian, who was watching, laughed in his heart.

What is the power of the Black Sky Demon God, isn't it just a small-scale earthquake? What is mysterious?

After a few more days of travel, the group traveled through the huge Zheyin Mountain Range and finally arrived at their destination.

It's a river valley.

The moment he arrived in the river valley, Song Nian was shocked.

Along the way, it was all cold and cold, who would have thought that in front of him, there was actually a green river valley.

The hot and humid breath was blowing in her face, and the lush plants were growing wildly, and at this moment, she seemed to return to the rainforest where she had traveled in her previous life.

After the rainforest, there is ...... Endless fields.

The swaying of the fields is the enchanting greenery of the coo-coa.

It turned out that these people of the Black Heaven Demon God Sect were able to find such a paradise on earth in the bitter cold land of the desert and use it to grow Gu Ke.

As for the formation of the tropical climate here, Song Nian is clear.

The ground movement just now illustrates the problem.

Zheyin Mountain is supposed to be the product of crustal movement, and among the large mountain ranges formed by this crustal movement, hot springs and geothermal heat are most likely to be generated. It's like the Huaqing Pool where the concubine bathes. Therefore, it is the geothermal heat that creates the wonder here, and the surrounding mountains perfectly block the cold from the north.

This is a natural logistics supply base...... Song Nian finally understood why Chu He was obsessed with Yinshan.

It's not a fanatical general trying to use human lives and bones to write fame and fortune for himself, but this Yin Mountain is really enough to be used as a core to dominate the northern grasslands.

Whoever owns this geothermal valley is equivalent to owning the grassland.

But to make the dragon city fly general, do not teach Humadu Yin Mountain...... Song Nian chanted in a low voice.

The Archbishop of the North looked at the green river valley in the distance and said with a smile: "Let's go, over there, we have prepared everything you need." ”

……

At the same time, at the northern end of the river valley, Chu He looked at the scene in front of him and muttered to himself.

"But the dragon city will fly and will not teach Humadu Yinshan...... I see, I see, I see......"

What appeared in front of him was a huge iron mine.

There is no need to dig rocks, this iron ore lies calmly on the ground, let others grab it.

This is an open-pit iron mine of excellent quality.

Next to the iron mine, there are iron-making furnaces, which produce and manufacture all kinds of iron tools day and night.

Machete, horseshoe, armor, arrowheads......

Countless things have been cast simply and crudely.

Zheyin Mountain is not only a logistics base for the Hu people, but also a huge arsenal.

But to make the dragon city fly will not teach Humadu Yin Mountain.

Without the iron ore, the nomads who raged on the grassland could only use white bones as arrowheads, and from then on, they changed from being able to fight well to being good at singing and dancing.

As for the fuel for ironmaking, along the way, the Chu River has also seen it, and it is a gift from nature.

Grain, miracle medicine, coal mines, iron ore - this is the true face of Zheyin Mountain.

Syllable!

A fierce whip was whipped on Chu He's naked back.
