Diamonds are also a material, but this kind of material is generally rarely used, and even often used by people as decorative items for rings.
And most of them are used by ordinary people on the Canglan Continent as diamond rings, and they are divided into many colors of diamonds, such as: red diamonds, pink diamonds, blue diamonds, green diamonds, etc. Depending on the market, the price of each diamond will fluctuate.
Low-grade diamonds are relatively easy to buy, but reaching six-star quality is probably not easy to find.
Fortunately, this diamond did not specify the type of diamond, and it is assumed that any color of diamond can be upgraded.
Zhou Yan informed Jin Sanyi, asking him to pay attention to whether there were any six-star quality diamonds for sale, and if so, to buy some six-star quality diamonds.
After everything was explained, Zhou Yan looked at the attributes of the upgraded [Fine Iron Vein].
[Building: Fine Iron Vein]
[Level: 60 (Needs Upgrade)]
[Quality: rrr]
[Special Attribute 1: A batch of fine iron ore can be randomly refreshed every 9 hours]
[Special Attribute 2: Increases the probability of high-level veins]
[Special Attribute 3: A batch of six-star fine iron ore is guaranteed to appear with each refresh]
[Special Attribute 4: At least three-star or above ore will appear]
[Special Attribute 5: There is a certain chance of appearing Fine Iron Yuan Stone]
[Special Attribute 6: Improves the efficiency of miners]
[Introduction: Rich mountains, the higher the level, the more high-level ore will be refreshed. Each refresh of ore requires 60,000 spirit coins.]
Zhou Yan was very satisfied with the attributes of this building. The refresh time has changed from 24 hours to 9 hours.
And the initial attributes are also very good, with at least three-star quality fine iron ore that can be mined.
Fine iron ore is much better than ordinary iron ore. Iron ore has a lot of impurities, and it needs to be refined after excavation to become fine iron.
This mine, when dug out, is fine iron, which can be directly used to forge equipment, saving a lot of time for blacksmiths.
As for iron yuan stone, it is a more precious material than fine iron, and iron yuan stone does not have a star rating. It can be directly used to forge spiritual equipment or above, which is very precious.
Zhou Yan contacted Xun Yu and told him about this building, asking him to arrange for people to come in and mine every day. The advantage of this mine is that it can be refreshed every day and can be mined every day.
As for the output and quality, it depends on luck.
Upon receiving the news, Xun Yu immediately arranged for personnel to come and mine. The miners in the territory had nothing to do, and with this mine, they could mine every day.
Zhou Yan also wanted to build more such mine buildings, but he had to encounter them first.
"I don't know what it's like inside." Zhou Yan walked in to take a look.
Walking in, he found that it was not dark inside, just like daytime. The mine tunnel was very large, and it was no problem for more than a dozen people to walk side by side.
After walking around, Zhou Yan found that it was very large. He thought that spatial stones were used as materials before the building was upgraded, so it is likely that this place has also been modified with spatial stones.
Such a large mine, even if thousands of people mine together, will not be crowded.
Not long after, Xun Yu had already arranged for people to come in, and happened to see Zhou Yan.
"My Lord, the people have been arranged." Xun Yu stepped forward and said.
"Let's see how the output of these ores is." Zhou Yan was very curious.
"Dig and see how the output of these ores is." Xun Yu quickly said.
The miners immediately started working, holding their mining shovels and picks to dig. Soon, they dug out pieces of fine iron ore, all of which were of five-star quality.
The quality of the ore mined is also related to the miner. The miners in front of them are all top miners with various bonuses, so they can naturally mine good ores.
"Not bad, this mine is only level sixty now. When it is raised by another thirty levels, I believe more high-quality fine iron ore can be mined."
Zhou Yan was very satisfied and said to Xun Yu: "This place will be left to you to arrange, I will go out first."
"Okay, Lord, please take care." Xun Yu still needed to stay and observe the specific output, and also to see the probability of iron yuan stone besides fine iron ore.
After Zhou Yan left, he began to build other buildings, the first of which was the previously obtained [Cultivation Room]. He was naturally very satisfied to have successfully obtained this building this time.
Territory prompt: "Building [Cultivation Room], [Cultivation Room] evolves into [Seclusion Room]."
Since a cultivation room had already been built, there was nothing to check for this building, so it was upgraded directly.
However, the second [Seclusion Room] could only be upgraded to level 50. Six-star materials were still too scarce.
Zhou Yan still had two special buildings to build. He took out one of them, which was the [Equipment Repair Workshop]. Zhou Yan was very excited to see what changes would occur after this building evolved.
Territory prompt: "Building [Equipment Repair Workshop], [Equipment Repair Workshop] evolves into [Automatic Equipment Repair Space]."
Zhou Yan smiled with satisfaction when he heard this.
"Could it be a place that can actively repair equipment?" Zhou Yan eagerly looked at this building.
It was a teleportation portal similar to space. Besides this portal, there were no other buildings. It was very simple and did not take up any space. Zhou Yan clicked on the attributes of this building to view them.
[Building: Automatic Equipment Repair Space]
[Level: 1 (Needs Upgrade)]
[Quality: rrr (Needs Upgrade)]
[Special Attribute: Can automatically repair equipment below Silver, currently can repair 100 pieces simultaneously, consuming sixty minutes.]
[Introduction: Damaged equipment can be thrown into the space. Each repaired equipment will consume a certain amount of spirit coins. The higher the quality of the equipment, the more spirit coins it will consume.]
The function of this building is very simple, but its effect is very powerful.
Countless pieces of equipment are damaged every day in the entire world, and it takes a lot of blacksmiths to repair them each time, which is a waste of manpower and resources.
With this automatic equipment repair space, the time of blacksmiths in the territory will be greatly reduced.
"Good building." Zhou Yan immediately began to upgrade this building.
After level twenty, Zhou Yan used spatial stones to upgrade it. After level thirty, the required material was still spatial stones.
However, after level forty, the material was replaced by spirit stones, of which Zhou Yan had the highest seven-star quality.
Fortunately, the subsequent materials did not change. Zhou Yan continued to use spirit stones to upgrade this [Automatic Equipment Repair Space] building to level 80.
After that, it would require eight-star spirit stones to upgrade.
He also ran out of materials, so he could only wait until later.
