Please be my partner.

On the way, Melen casually asked, "How do I trade Magic Gold Coins?"

Elder Rabbit gave Mellen a deep look and said, "It seems that the guest has just arrived in the Spirit World and doesn't know much about this place. If I'm not mistaken, the guest should be here for the exchange meeting in Blue Crystal City, right?"

Mellen didn't intend to hide it, so he nodded without hesitation and said, "That's right."

Elder Rabbit nodded slightly and said, "The spirit world also has its own currency. Gold coins can be traded as currency, and magic gold coins are no exception. Of these currencies, magic gold coins are naturally the most valuable."

"Of course, some spiritual communities prefer bartering as a trading method. These spiritual communities are not necessarily weak, but their living habits and thinking are usually more...conservative."

Melen nodded to show that he understood. As an equivalent currency that can be used in all realms, the magic gold coin naturally has a higher level of implicit added value.

Soon, Melen was taken to a vehicle. The vehicle was pulled by a three-meter-tall creature that looked somewhat like a dinosaur and seemed quite docile.

Entering the carriage, the view suddenly opens up. The space inside the carriage is at least a hundred times larger than what you see from the outside. There are fixed shelves in it, on which are placed a wide variety of goods.

There are all kinds of crops, spiritual plants, radiant minerals, glittering gems, and broken utensils imbued with mysterious rhythms...

The elder rabbit said, "These are just the exhibits of our merchandise for sale. If you like something and want to buy in bulk, we also have it."

Although he said so, the elder rabbit did not think that Mellen, a lone wolf, could buy too many things. He naturally had his own purpose in agreeing to the transaction.

Mellen looked all the way and found that these vegetables and fruits from the spiritual world all looked delicious. The rabbit elder indicated that he could taste them at will, so he just picked them up and started to chew them without any hesitation.

Some fruits that looked delicious made his eyes light up and he bought them right away. Some that looked even tastier made him put on a mask of pain the moment he took a bite. But he couldn't spit out what was in his mouth in front of the rabbit elder, so he had to eat them all and then stayed away from them.

Later he learned his lesson and politely expressed that he was a human being with normal taste and really couldn't accept some weird tastes.

The rabbit elder nodded with amusement and pointed out some vegetables and fruits that were highly regarded by humans. After tasting them this time, Melen couldn't help but give a thumbs up.

Minerals are what Melen is more interested in. There are at least thirty or forty kinds of minerals here, and they are all relatively common types in the spiritual world. The Spirit Rabbit Clan collects these purely to earn hard-earned money, and they can only get more profits from rare minerals.

As for common minerals, Mellen bought some of each at random, but what caught his attention was a rare mineral commonly found in the spiritual world called spirit crystal.

Spirit crystal looks like a translucent crystal, but it also has the properties of metal.

The reason why spirit crystals are rare is simply because of their precious properties. As long as they are in an unsaturated state, they can absorb and store various elements without limit. To a certain extent, this means absolute immunity to spells.

The reason why spirit crystals are common is that their birth relies on the universal rules of the spirit world. Their traces can be found in almost all the veins in the spirit world, and they are widely distributed.

The Colossus Fortress has three sets of power cores, namely the core furnace, the elemental energy pool, and the void engine. These three sets of power cores complement each other, can influence and add to each other, and are also related to the many functional accessories and weapon systems of the Colossus Fortress itself, and none of them can be missing.

And spirit crystal is one of the important materials for creating elemental energy pools.

Melen immediately asked, "How many spirit crystals do you have? I want them all."

Elder Rabbit was startled. After a moment's hesitation, he said cautiously, "Although we don't bring many spirit crystals this time, it's still about ten tons. Are you sure you want them all?"

Mellen asked directly: "How much?"

Elder Rabbit said, "Although Spirit Crystals have excellent properties, they are not actually a scarce resource in the Spirit World. Their only drawback is that they are too scattered, making them difficult to collect. Therefore, their price is slightly lower than that of ordinary rare resources. Based on our previous prices, they can be sold for around 800 Magic Gold Coins per ton."

Mellen's mouth twitched slightly. It was not that the price was too expensive. On the contrary, it was still within his acceptable range.

He mainly felt that the cost of building the Giant Fortress might be far beyond his expectations.

I didn't have any idea before, but now that I think about it carefully...

Excluding the consumption of ordinary materials and some technical costs, the three power cores alone are already terrifying.

The core furnace is actually the simplest. The low-end version can be replaced by Garuru's Source Energy Furnace. Of course, this must be done after the mechanical dog is promoted to legendary. The high-end version requires a mechanical saint-level furnace core.

The elemental energy pool requires at least one hundred tons of spirit crystals, and there is no upper limit. The more, the stronger. The high-end version needs to integrate the complete law core of the four elemental worlds of earth, water, fire, and wind. Of course, the low-end beggar's version only needs fragments of the four elemental laws to barely run.

The Void Engine requires the brain and complete cerebrospinal fluid of a Void Behemoth, as well as a crystalline cage made of metal that has at least very strong Void properties. This is a low-end version. If a living and adult Void Behemoth can be imprisoned, all the Void Laws it possesses can be used.

In addition to the above low-profile and high-profile versions, there is also a real top-profile version...

You know, even Mechanical Saints have strengths and weaknesses.

You know, there are also differences in the elemental world.

You know, there is a king among the monsters in the void.

Even if it is built according to the lowest standards, the elemental energy pool and void engine alone may cost 50 to 100 million magic gold coins. If you add the supporting weapon system, defense system, space shuttle, etc., it is estimated to cost more than 200 million magic gold coins.

To be honest, after roughly figuring out the price, Melen hesitated. He had wanted to build the Giant Fortress first because, according to the description, this kind of weapon of mass destruction was too suitable for large-scale wars. Whether it was the war that was bound to come in the space-time rift or the invasion of the abyss world later, he would need war weapons of this level.

But, it’s so damn expensive!

He only has over 7 magic gold coins on him now, which is a bit far from enough.

The transaction with the Rabbit Elder was completed smoothly. In addition to ten tons of spirit crystals, there were also many miscellaneous items, which cost a total of 8100 magic gold coins.

With this friendly transaction, the two sides have established initial trust.

Mellen returned to the small camp she had built and continued cooking. Not long after, a few little rabbits came over with some food, saying they wanted to give it to Mellen. Then they stared at the giant carrot and drooled.

Mellen chuckled, cut some of the giant carrot into pieces, and gave them to the little rabbits.

He originally threw out this giant carrot as a way to attract others, to feed it to the rabbits to increase their favorability, so of course he wouldn't be stingy with it.

As long as the favorability is high, Melen will not only be able to get more information about the spirit world from the rabbit, but may also be able to unlock more products.

Based on the dragon's blood's natural sensitivity to treasures, Golden Hair discovered that there were some more precious treasures hidden in the other carriages of the rabbit team. Perhaps the rabbit elder still had some concerns, so he did not take them out in the transaction just now. Of course, it is also possible that those things have been reserved in advance by others, so they cannot be sold to the outside world.

It was understandable that the elder rabbit had concerns. After all, in its opinion, Mellen's behavior was indeed a bit strange.

Although he seemed to be in danger after being besieged by the six-eyed sand scorpions, Melen never showed any panic. After the danger was over, he followed their team without hesitation and was not worried that they would take tough measures. Later, he even entered their team alone to trade.

Such existence is either stupid or has support and confidence.

In the opinion of the rabbit elders, being on guard is one thing, but as long as Melen does not show any ill will towards the Spirit Rabbit Caravan, they should not take the initiative to make enemies with him.

The convoy was moving much slower than Mellen's own travel. Since he was not in a hurry and also needed to adapt to the rules of the spiritual world, he just moved forward slowly, just to appreciate the scenery of the other world.

After the communication, Melen also got more information from the rabbits.

For example, this desert suddenly appeared in Tianfeng Territory decades ago. Some powerful people in the spiritual world suspected that there were rare treasures buried in the desert, but after spending a lot of money to search, they found nothing. However, the monsters born in this desert are of high value and are the gold-mining ground for several small spiritual tribes nearby. The Spirit Rabbit Tribe is one of them.

For example, there are not two suns in the spiritual world, this is only the case in Tianfeng Territory. In other areas of the spiritual world, you may see the wonderful sight of three, five, or even ten suns across the sky. Of course, there are also areas where there is no sun, but a bright moon in the sky and starlight.

For example, Tianfeng Territory was originally just an ordinary area in the spiritual world. It was a long time ago that a spiritual world tribe called the Lifeng Clan rose up and tried to stabilize this area into a new spiritual world node, and then the name Tianfeng Territory gradually came into being.

Unfortunately, for some unknown reason, the Gravel Wind Clan failed, and the entire clan inexplicably died out. Then the Blue Crystal Clan discovered this place. After a period of exploration, the Blue Crystal Clan decided to continue the unfinished work of the Gravel Wind Clan. After all, the spiritual world node is too important for the development of a spiritual world clan.

Apart from anything else, just stabilizing the rules that often change suddenly is enough to avoid most of the risks in the spiritual world. A comfortable living environment can attract a large number of spiritual tribes to come and seek refuge, and at the same time, it will also attract covetous eyes.

However, even if the Blue Crystal Clan inherited the legacy of the Gravel Wind Clan, it would not be an easy task to build the Sky Wind Territory into a node. This would require the efforts of the entire clan for thousands or even tens of thousands of years, and it might not be successful in the end.

Of course, even the current 'semi-finished product' has already brought unimaginable huge benefits to the Blue Crystal Clan.

Chapter 224 Arrival at Blue Crystal City

“Gulp gulp!~”

The soup in the pot continued to surge with a rich aroma. In addition to stewed vegetables such as greens, carrots, and lettuce, some sliced deep-sea fish was also added to enhance the flavor.

There were only Melen and Elder Rabbit at the dinner table. The sauce in front of Melen was a little red and contained spices similar to chili, while Elder Rabbit's was lighter.

Melen watched the rabbit elder eat the fish fillet without hesitation and couldn't help but say, "I thought you Spirit Rabbits were all vegetarians. I've never seen you eat meat before."

The rabbit elder glanced at Mellen and explained, "We Spirit Rabbits are omnivores. We prefer vegetables, but it's not that we can't eat meat. We've already eaten all the meat we brought with us on the way, and the meat of desert monsters is generally tainted with poison and cannot be eaten."

The elder rabbit picked up another piece of carrot and chewed it. After a while, he said, "It's delicious."

After a brief pause, it said, "Mr. Mellen, we in the Spirit Rabbit Tribe really like these giant carrots. I wonder if you could sell us some seeds?"

The rabbit elder initially agreed to Mellen's trade request, and wanting to get the giant carrot seeds was one of the important reasons.

After a period of verification, the rabbit elder has determined that although the giant carrot is not a spiritual crop, its taste is very popular with the spiritual rabbits and it has no other side effects, so it is ready to trade with Mellen.

This was a result that Mellen had anticipated long ago, so he naturally had no reason to disagree.

To put it bluntly, the only attribute of giant carrots is "delicious", and they need a specific target audience (rabbits), so to be honest, their value is not that high.

but……

Mellen first expressed his agreement to the deal, then added, "Elder, this giant carrot requires a very special environment to grow successfully. Even if I give you the seeds, you probably won't be able to grow it."

This was a precautionary measure to prevent the rabbits from thinking he was deceiving them if they couldn't produce any crops.

The so-called special environment naturally refers to the fairy tale kingdom. This kind of thing born in fairy tale fantasy is difficult to perfectly replicate even if the seeds are materialized into reality.

Hearing this, the rabbit elder said confidently: "Don't worry, we, the Spirit Rabbit Clan, are the best at farming. As long as we have seeds, we can grow them even without a suitable environment."

Mellen didn't say anything more about this and completed the transaction directly.

After that, Melen's relationship with the Spirit Rabbit Clan became more and more harmonious, and the Rabbit Elder also invited him to a new transaction.

The rabbit elder said, "In fact, we, the Spirit Rabbit Clan, are somewhat gifted in spiritual perception, so we are able to find some unique treasures through excavation and exploration. I wonder if you are interested in taking a look, Melen."

Of course, Mellen agreed happily.

He joined the convoy again. This time, the rabbits looked at him with friendly eyes. Some brave little rabbits even surrounded him with a smile.

Feeling this simplicity, Mellen's mood also improved.

The two came to a slightly smaller carriage. The space here was also very large, but there were fewer goods on display. Among them were mysterious instruments, rare minerals, spiritual plants, crystal gems, etc.

Mellen looked at the nearest shelf, on which was placed a weapon that looked like a long stick, but this stick was as thick as two hands held together and more than three meters long. It was obviously prepared for large life forms.

There are mottled marks of battle on the long stick. Although it no longer has extraordinary properties, the rhythm still remains. Some professionals may be able to figure out something from it.

There are many similar things here, not just weapons, but also some other kinds of tools.

Elder Rabbit said, "These are what we found in the ruins, and some are from ancient battlefields. They all look broken, but there may be dormant extraordinary items mixed in, waiting for their true owner to arrive."

Melen hadn't expected that there was such a thing as spiritual objects teaching themselves in the spiritual world, and he couldn't help but show interest, but he looked left and right and didn't find any special instrument.

As he walked, he suddenly saw stones of various sizes placed on the shelves in front of him.

Elder Rabbit said, "These are hidden stones unearthed from the mines. Some mysterious objects containing extraordinary things were buried underground. After the changes in the rules, these hidden stones may have formed. Because of the chaotic rules of the spiritual world, even saints find it difficult to discern the specific treasures within. Therefore, the trading model of gambling on stones was naturally born."

"It's possible to find ordinary minerals or spiritual plants in hidden stones, or rare items and divine materials. It all depends on luck, knowledge, and courage, so it's sought after by many people."

Mellen was also familiar with this game of 'one knife makes you poor, one knife makes you rich'. Having a pair of eyes that can see through everything is almost a standard feature of many novel protagonists, so games like gambling on stones are usually their first pot of gold.

Unfortunately, Melen did not have this ability. Although the stones in front of him contained a strong spiritual glow, they were blurred under the cover of chaotic rules, and he could not tell what was inside.

Suddenly, Melen had an idea and thought of the golden retriever in the fairy tale kingdom. The latter has the blood of a dragon and might be more sensitive to precious treasures.

Thinking of this, he no longer hesitated and immediately contacted the golden retriever. After hearing the call from his master, the golden retriever was also very excited and immediately began to sense those hidden stones with all his strength.

Soon, under the confident command of Golden Hair, Melen picked three hidden stones with a smile on his face.

Seeing Mellen's expression, Elder Rabbit was a little suspicious, but he quickly completed the transaction.

The next step is to cut the stone. Although it is not simple, it is not too demanding either.

As the first hidden stone was cut open, a pure light bloomed out, and a flower that looked ordinary but was between reality and illusion was seen floating in the air, swaying gracefully.

Melen's eyes rippled. Could this be some kind of amazing medicine?!

Elder Rabbit said calmly, "Orchid flower, one of the ingredients for the spirit recovery potion, is of average value."

Mellen: ...

Seeing Mellen in a daze, Elder Rabbit kindly explained, "This kind of orchid isn't very common in Skywind Territory, but it's said there's a vast sea of orchids in Shadowmoon Territory. Every time March is high in the sky, the sea of orchids collectively releases a spiritual aura, creating a rare spectacle."

The second hidden stone was opened, and a long spiritual charm spread out, revealing a corner of some kind of instrument.

Melen's eyes rippled again. Could this be some dormant extraordinary object? !

Elder Rabbit said calmly, "It's a broken fragment. The mysterious element within it has completely disappeared. While the material itself might be good, its overall value is average."

Mellen: ...

Next came the third and largest piece. Compared with the previous two times, this one was very normal and could be called unremarkable.

Mellen's eyes rippled for the third time. Could it be that...

Elder Rabbit said calmly, "This time it's not bad. Although it's just an ordinary spiritual crystal, it's better than the previous two. At least I broke even."

Mellen: ...

Mellen looked at the golden retriever in the fairy tale kingdom, who tucked his tail between his legs, shrunk his head, and made a "woohoo" sound.

He sighed, realizing that this matter could not be blamed on Golden Hair. If the dragons could sense the items in the hidden stone, then this kind of thing would not have formed a fixed industrial chain, because with the greed of dragons, if there were any good things, they would have taken them all away long ago.

Today's incident has further strengthened his determination to fight against gambling and drugs.

Mellen himself doesn't like uncertain things. In his opinion, whether it is a battle or something else, it is best to be able to lock in the final result before things happen.

Next, Melen bought some precious minerals, thus completing the transaction.

The journey after that was very peaceful. Because of their close relationship, the Spirit Rabbit Tribe seemed to have included Melen in their protection. Occasionally, when he was besieged by monsters, they would even come to help him.
