Soaring above the sky every day, looking at the unchanging scene below, Lao Jiu really felt bored. Fortunately, I can occasionally see some ocean overlords hunting on the surface of the sea, which can be regarded as adding some fun to Lao Jiu.

As the saying goes, hard work pays off. After two days, Lao Jiu finally found an island in the southeast of the Peace Islands. This island is about 20,000 kilometers away from the Peace Islands. The size of the island is not very large, less than five square kilometers.

It's a pity that there are no mineral resources on this island, but it can be a springboard for Lao Jiu to search for other islands. Just when Lao Jiu was preparing to reconnoiter the island, Mi Baoer sent him a message, which made Lao Jiu have to rush back as soon as possible.

Because of the news sent by Mi Baoer, it really made Lao Jiu too excited. That's the mine under the extinct volcano, which has been mined to the cuprite vein. This is not important, the important thing is that on top of the copper vein, there are a large number of colored copper ore particles.

These colored copper ore grains, in the form of colored crystals, vary in size and shape. According to their attribute prompts, the only function of these particles is to make spatial attribute equipment.

After getting this news, can Lao Jiuyan not be excited? And according to Mibaoer, the number of these associated colored copper ore particles is still very considerable. If it is used well, it is enough to build a powerful gold empire.

So after receiving the news, Lao Jiu rushed back as soon as possible. What resource-rich islands, in Lao Jiu's current opinion, are not as good as space equipment, and they came out in batches. Because this is the equipment that players urgently need at the moment.

Along the way, Lao Jiu only took less than three hours to come to the bottom of the extinct volcano. Beneath the extinct volcano today, it has long been transformed into a real underground city by Mibauer. And when Lao Jiu arrived, the other women had already gathered here.

Coming to the dungeon, here is a renovated factory, at this time the women are in a circle, in the middle, there are three craftsmen building something. One of them was a bit older, while the other two looked a bit like apprentices.

"What's going on?" Lao Jiu leaned in with a curious face, and by the way, patted Mi Baoer in front of him and asked.

"Yikes! Brother Jiu, are you all back? Turning around and seeing Lao Jiu, Mi Baoer exclaimed in surprise, and then explained to him, "This is the best jewelry craftsman in our empire, which is equivalent to an alchemist, who can make attribute jewelry, and those two are his disciples." ”

"Oh? Is it done? Lao Jiu asked curiously, "Didn't you just find out?" Looking at the situation here, it seems like it's been a few days. ”

"I'm not afraid that you will be happy in vain, and I will tell you if you don't make a result, what if it doesn't work?" Mibael rolled her eyes and said, "At present, it is already possible to make space jewelry, but the space is limited and it is still in the experimental stage." ”

"What? Are there still hurdles to overcome? Lao Jiu looked at her and asked.

"hard, look at this." At this time, Bai Ruyu glanced at Lao Jiu, handed him a ring and said.

Lao Jiu was puzzled and found that it was a golden ring, which was inlaid with colored crystals the size of a bean, which looked really difficult to see. However, Lao Jiu took a look at the attributes, but his eyes couldn't help but light up.

Ordinary storage ring, one cubic meter of storage space! Although the properties are very simple, they are very practical. If ordinary players can have one, it's definitely the equivalent of an artifact.

"This is very good, there is enough cubic meter for ordinary people, it doesn't matter if it looks ugly!" Lao Jiu looked at Bai Ruyu suspiciously and said.

"It's okay to look ugly, but the cost is not low." Baili Piaoxue said a little speechlessly, "This ring must be made of gold and copper of high purity, and colored copper. Gold and copper are just that, our current storage is still very large, but the color copper is pitiful. ”

"Just this cubic meter of space consumes nearly a pound of colored copper ore, so calculated, this kind of cubic meter of space rings, we can make hundreds of them, it is too much. The cost is high and the quantity is small, which is simply chicken ribs. ”

"Don't jump to conclusions, didn't Master Wu say that there was a new discovery? Let's listen to what Master Wu has to say. At this moment, the three craftsmen in the middle finally stopped, and Long Sifeng glanced at a few people, frowned and said.

"Did Master Wu find anything? Is there anything that can be done to improve the purity of the copper ore particles? If there are any conditions, Master Wu will open his mouth, and we will definitely try our best to satisfy the master. ”

"Little old man Wu Zhongtian, these are my two adopted sons, Wu Zhigao and Wu Zhiyuan." Master Wu, who stopped working, saw Lao Jiu at this time, and hurriedly saluted him first, and then said, "Mrs. Hui, at present, this kind of spatial attribute ore can only be combined with high-purity gold and copper. ”

"And our current production of colored copper ore particles, the purity is obviously not up to the requirements, in addition to the use of a large number of ore purification, there is an old way. It is nourished by using high-purity, low-grade mineral liquid. ”

"In other words, we can use high-purity gold-copper ore liquids to make the colored copper ore particles extremely pure. However, this method will not only consume a large amount of gold and copper ore, but also be very good-timed. ”

"To be specific, the proportion of consumption, as well as the requirements for purity, the more detailed the better." Lao Jiu frowned, then looked at him and said.

"Back to the Emperor, after my experiments in the past few days, I have come to some conclusions, so I will talk about them in detail first." Master Wu bowed to Lao Jiu, then thought for a moment and said, "To build a space, you first need high-purity colored copper, and the purity must be at least 90%. ”

"Secondly, it is supplemented by gold and copper with a purity of more than 95%, and the size of the space depends on the volume and purity of the colored copper. Like the ring in your hand, it is made of the smallest colored copper with a purity of just 90. ”

"And to improve the purity of colored copper ore, it is about one to one hundred. To put it simply, 100 cubic meters of pure gold and copper ore liquid can increase the purity of 10% of the color copper vein by 10%. ”

"Uh...... How many storage rings can be made from that cubic meter of colored copper? It's this one-cubic-meter. Lao Jiu didn't seem to care about the consumption of gold and copper ore, and directly asked the main question.

"Hmm...... After processing, it is conservatively estimated that there are about four million pieces! Master Wu thought for a moment and said.

"Uh...... So much? How long does it take to purify one cubic meter of colored copper ore? Lao Jiu was stunned for a moment, and then asked happily.

"According to the process of my experiment, one day is equivalent to one percent of the purity." Master Wu said.

"That's easy to do, we have gold and copper mines, and we will start purifying them now." Lao Jiu said happily, "But the ring you made is really ugly, it seems that we will have a special designer in the future." ”

"Can you not be too happy?" Looking at Lao Jiu's appearance, Baili Piaoxue glanced at him speechlessly and said, "Do you know what the purest gold and copper ore is?" That's the equivalent of gold coins! ”

"Do you know how many gold coins there are in a hundred cubic meters? That's more than 10 million gold coins! And depending on the jewelry, the gold and copper required to make each piece of jewelry are about five gold coins on average. ”

"And the color copper ore we are currently mining is only forty on average, if we want to improve it to more than ninety, how many gold coins do we need? In this way, the amount of gold we have to invest has almost reached 100 million. ”

"Even on average, the cost of a storage piece of equipment is about thirty gold coins, not counting labor and various handling fees. How much should we sell? Thirty gold or fifty gold? How many people do you think will be able to afford it? ”

"Uh...... For storage equipment, even a hundred gold coins are not expensive, right? Lao Jiu was stunned for a moment by what Baili Piaoxue said, and then looked at him and asked puzzled.

"That's a hundred gold coins, not a hundred RMB! Converted to RMB, it's a full 100,000! Long Sifeng looked at Lao Jiu, rolled his eyes and said, "What?" Now that you have become a local tyrant, hundreds of thousands of RMB, is it no longer money in your eyes? ”

"Uh...... I'm used to the game, and I always feel that a hundred gold coins is about the same as a hundred. Lao Jiu looked at her and said with some embarrassment.

"You, I think if you go bankrupt in the future, how will you live!" Baili Piaoxue also said speechlessly.

"Don't worry, as long as the game doesn't fall, I won't fall! Even if the game falls, the surplus food we keep is enough for us to live happily for the rest of our lives. Lao Jiu said very generously, "Besides, our real purpose is to earn gold coins from other empires." ”

"You know, if you have a storage ring, for an empire, it will often play a decisive role. In the case of that army, if every soldier was equipped with a storage ring, they could travel lightly. ”

"Whether it is carrying grain and grass, or weapons, etc., it will play a key role. Take the undead cavalry as an example, if it is equipped with a storage ring, it will definitely become a real ghost army, coming and going without a trace, which not only solves the problem of food and grass, but also speeds up the march. ”

"What do you rely on to fight? It's mobility and equipment! If all of our armies are equipped with storage rings, then our Escapees will become the most powerful army in the entire game. ”

"But if you sell to other empires, won't we have no advantage?" Mi Baoer looked at Lao Jiu puzzled and said.
