Pure copper!

Looking at the purple-red copper block the size of a quail egg in his hand, Lin Luo thought in shock in his heart.

At this time, the wound at the main stem of the Zhijin Spirit had healed, and the copper liquid flowing out in a liquid state was also separated from the Zhijin Spirit's body, and quickly solidified into a solid copper block.

Then, the copper block was rolled up with a leaf by the golden spirit and handed to Lin Luo's hand.

Lin Luo didn't expect that the pure copper of the Zhijin tribe would be "smelted" in such a way.

A plant that can absorb the metallic elements in the ore and separate them to form high-purity metals.

It's definitely amazing, so to speak.

Copper grass!

In an instant, a plant on the earth appeared in Lin Luo's mind.

The scientific name of copper grass is Haizhou fragrant herb, which is an annual herbaceous plant.

Because it mainly grows in the area where copper mines are located, people often look for copper mines based on the distribution of copper grass.

Similar to the golden grass, the copper grass is also a magical plant that can absorb copper metal from the soil, which is also the origin of the common name copper grass.

Because of this miraculous ability, copper grass is widely used to control copper metal pollution in the soil in modern times, and it is a very rare environmentally friendly plant.

Even, in the case of high copper content in the soil, the copper metal absorbed by copper grass can reach one-third of the same amount of ordinary copper ore, which can be used as a raw material for copper smelting.

Of course, compared to the golden grass, the copper grass is undoubtedly a small thing.

After all, copper grass can only absorb trace amounts of copper from the soil, while it can absorb metal elements directly from metal ores and separate them from the plant.

But it has to be said that the magical effects of the two plants are extremely similar.

However, this is obviously not good news for Lin Luo.

Originally, he had always thought that the Zhijin tribe had some unknown unique smelting technology, so it could smelt pure copper with extremely high purity.

Unexpectedly, the pure copper of the Zhijin tribe was all refined by the Zhijin Spirit in such a special way.

Such a result naturally disappointed Lin Luo.

At the same time, he finally understood why when he proposed to trade the smelting technology, both the Golden Witch and the Golden Spirit had puzzled expressions.

"I'm sorry, but I had some misunderstanding about your Sachin tribe. ”

After thinking about all this, Lin Luo immediately got up and said, "Since the smelting technology doesn't exist, then I won't bother much. ”

The pure copper of the Zhijin tribe is all refined from the Zhijin Spirit, not some smelting technology, and it is impossible to take it away at all.

Therefore, Lin Luo's previous thoughts were naturally in vain, and there was no need to stay any longer.

As for pulling the Zhijin tribe into the tribal alliance, this special smelting technology can be obtained through this method.

Lin Luo also thought about it in his heart, but he quickly vetoed it.

After all, he is only one person now, and it is impossible to use force to deter him like he did with the fox tribe in the beginning.

Moreover, this place is too far away from Zhushan, even if the Zhejin tribe is willing to agree to join the tribal alliance.

If the entire Zhijin tribe were to be relocated, it would take at least a little more than a month to get there.

With the current strength of the Zhejin tribe, it simply cannot withstand such a long period of migration, and it is very likely that it will be wiped out in the process of migration.

At that time, if you don't get it right, he will also be implicated.

Therefore, Lin Luo made a decisive decision to leave.

"Don't rush to leave. ”

Seeing Lin Luo's movements, Zhi Jinling opened his mouth and said, "Regarding the technique of refining gold, it is not that it cannot be traded. ”

"What?"

Hearing this, Lin Luo suddenly stopped, looked at Xue Jinling in surprise and asked, "Ling, are you telling the truth?"

"Of course it's true!"

Xue Jinling replied affirmatively.

After receiving confirmation from Zhi Jinling, Lin Luo immediately sat back on the stake with a happy face.

He didn't expect that there was still a possibility of success in this matter.

"I heard Jin Mu Yu report before, you and he met at the Evil Tribe, then you should have seen it, the former residence of our Yakin Tribe, right?"

After Lin Luo sat down again, Xue Jin Ling did not immediately talk to him about the transaction, but said as if recalling: "In the past, the residence of our Xue Jin tribe was not what it is now.

At this time of year, the whole mountain should be full of purple flowers, although those golden grasses are ......"

Facing Zhi Jinling's reminiscence, Lin Luo did not interrupt, but just listened quietly.

And as Zhi Jinling continued to tell, Lin Luo gradually understood what it meant by the refining technique it said before was not that it could not be taken out for trading.

Just as bamboo grows all over the Bamboo Mountain, there was also a golden grass growing all over the mountains and fields on the Golden Mountain, where the Zhijin tribe lived.

Although those golden grasses cannot be compared to the golden spirits, they also have the ability to absorb metal.

They have well-developed root systems and are deeply rooted to absorb metals from ores buried deep underground.

In fact, most of the pure copper owned by the Zhijin tribe comes from these ordinary Zhijin grass.

Like the copper grass, these common herbs are all annual herbaceous plants, and when they wither during the dry season, the people of the Khaejin tribe collect their seeds first.

It is then harvested and thrown into a crucible to refine pure copper.

This point is very similar to copper grass in theory, which can be used as a copper smelting material.

However, the ability of the golden grass to absorb metals is many times stronger than that of the copper grass.

The metal content of its plants is comparable to that of the finest quality ores.

In addition, the plant itself also has a magical catalytic effect, which can have a catalytic effect on the metal and reduce the temperature of its melting point.

It is precisely because of such a natural catalyst that the Zhijin tribe can melt and cast copper into various utensils just by the temperature of firewood burning.

However, after the Shan tribe occupied the Golden Mountain, they uprooted all the golden grasses that were still in the growth stage and smelted them.

Because, although the copper can be obtained by refining it with golden grass, it is extremely low in terms of yield, and it is far from meeting the needs of the Yakini tribe.

Therefore, the Hideous tribe abandoned the method used by the Yakjin tribe and chose to directly use slave mining and refining to quickly obtain a large amount of copper.

In addition, Zhi Jinling also told Lin Luo some more detailed things about Zhi Jincao.

For example, metal is necessary for the growth of the golden grass, and in the process of growth, the golden grass must absorb metal elements in order to grow more vigorously.

Therefore, the golden grass absorbs a large amount of metal from the ore and stores it in the plant, in fact, it is only for its own growth needs.

In addition, it is theoretically possible to absorb any metal not only copper, but also copper.

The reason why the Zhijin tribe only has bronze artifacts is because their residence is built on a large copper mine.

Here, the rest of the metals are very low.

Of course, being able to absorb any metal is only theoretical.

Because of the relationship of strength, at present, it can only absorb softer metals such as copper and lead, and cannot absorb metals with higher melting points and stronger hardness such as gold and iron.

That's why the Yakin tribe chose a copper mine as their place to live.

......

Originally, Lin Luo listened with great interest when he first heard Zhi Jinling's story.

But as Zhi Jinling talked more and more, the more detailed he became, and even included some secrets that would not be casually revealed to strangers, Lin Luo gradually panicked.

"Ling, let's talk about the transaction first!"

Lin Luo immediately spoke, interrupting Xue Jinling's words.

He was looking for the Zhijin tribe this time, just to trade smelting technology, and he didn't want to cause other things.

Xue Jin Ling told him in such detail at this moment, these things involving the secrets of the Xue Jin tribe made Lin Luo suddenly have a very bad premonition.

"Okay!"

For Lin Luo's interruption, Zhi Jinling didn't get angry at all, and asked him, "Then how are you going to trade?"

"I have some jerky of ferocious beasts on me, and I can trade them with your tribe for the seeds of the golden grass. ”

Lin Luo said directly.

Through what Zhi Jinling said just now, Lin Luo already knew the wonderful use of Zhi Jincao.

Although the production is limited, it is a good way to refine high-purity metals.

"No problem. ”

Hearing Lin Luo's words, Zhi Jinling nodded very simply in agreement.

That's agreed?

Seeing that Zhi Jinling nodded in agreement so simply, Lin Luo couldn't help but be slightly stunned.

To be honest, it was a bit of a surprise.

After all, Xue Jinling had revealed so many secrets before, which made Lin Luo feel very uneasy.

However, just when Lin Luo just breathed a sigh of relief and was secretly happy that the transaction was successfully completed.

Xue Jinling continued, "However, are you sure you can find a suitable place for the growth of Xue Jincao?"

"Uh......"

Hearing Zhi Jinling's words, Lin Luo was instantly stunned.

It was already obvious what he meant, questioning whether he could find a metal ore and a softer metal.

After all, the growth of the golden grass must absorb metal elements, otherwise let alone refining and harvesting metals, even the golden grass will not be able to grow and survive at all.

In the face of Zhi Jinling's questioning, Lin Luo's answer was naturally no.

He didn't know anything about how to find metal veins, and he didn't even know what copper ore looked like until he went to the Recalciner Refinery.

Looking at Lin Luo's dumbfounded appearance, Xue Jinling spoke again: "I can personally breed a seed for you, as long as you carry that seed in a suitable place for its growth, the seed will produce strong spiritual power fluctuations.

This will allow you to find a suitable place for the goldenrod to grow. ”

"Spirit, say whatever you want!"

Regarding Zhi Jinling's words, Lin Luo's face did not have the slightest joy, but instead said directly to Zhi Jinling with a serious face.

As the saying goes: nothing to be courteous, either a traitor or a thief!

The preciousness of the seeds nurtured by the spirit was very clear in Lin Luo's heart.

After all, there are three peach trees planted on Zhushan, which were nurtured by Pan Taoling himself.

Usually, there are special people who take care of them day and night.

Now, Xue Jinling suddenly said that he would personally breed a seed for him, and Lin Luo naturally didn't believe that it was a good thing that fell from the sky that he had touched it.

This made Lin Luo understand why Xue Jinling had told him in detail about all the things about Xue Jincao before, and even did not hesitate to expose some secrets.

The purpose is to first let him know the various uses of the golden grass, and then tell him at the last moment.

If you want to grow the golden grass, you need the seeds that it has cultivated itself.

"Okay, then I'll make it clear. ”

Seeing that Lin Luo had already guessed its purpose, Zhi Jinling stopped detouring around the bend and said directly to Lin Luo: "In exchange, I hope you can help us rescue the clansmen." ”

"I'm sorry, but I can't do that. ”

When Zhi Jinling's words fell, Lin Luo immediately got up and stood up without thinking about it.

Help the Yakin tribe rescue their people?

In Lin Luo's opinion, this kind of behavior is simply no different from sending him to death.

When he went to the refinery of the Hideous Tribe to investigate before, Lin Luoke clearly sensed that there were four bloodline warriors in the refinery.

Although the flesh warrior he met at the beginning had already left and was not in the refinery, the four bloodline warriors were not something that Lin Luo could deal with.

After all, the Zhijin tribe didn't even have a bloodline warrior now, so it couldn't help much at all.

Therefore, after Lin Luo heard the conditions put forward by Xue Jinling, he decisively chose to refuse.

"Don't be in a hurry to refuse, it's not as dangerous as you think. ”

Looking at Lin Luo, who was about to get up and leave, Zhi Jinling spoke again to stop him.

"There are four bloodline warriors in the refinery of the Hideous Tribe, how can it not be dangerous for me to go there to save people?"

Lin Luo said to Xue Jinling with a depressed face.

"It's not for you to actually fight the people of the Hideous Tribe, you just need to cause a riot to attract attention. ”

Xue Jinling explained to Lin Luo, "Three days ago, we had a totem warrior pretend to be captured and enter the refinery of the Vicious Tribe.

He would secretly inform the other fighters to flee in the event of a riot.

Today, Kaneki went to the refinery to communicate with the totem warrior with a signal.

Now, confirming that he has informed the other fighters, Kaneki has also informed him that he will do it tomorrow. ”

Speaking of this, Xue Jin Ling paused slightly, and then said: "You have also seen the current situation of our Xue Jin Tribe, with this strength, tomorrow's plan is very likely to fail.

So, I hope you can help our tribe.

And as a token of appreciation, I will give you some seeds of the golden grass, as well as a seed that I have nurtured myself. ”

After saying this time, seeing that Lin Luo was about to shake his head, Zhi Jinling directly interrupted him and said, "You don't have to rush to answer me now, it's not early now, and there is no suitable place to live around here."

Why don't you stay in our tribe tonight and give me an answer tomorrow!"
