Global Ocean Tortoises: Developing Cities on Their Backs

[Upgrade cost: Standard wooden board x10000. Standard square stone x10000. Red brick x10000. Glazed tile xlOOOO]

[Upgrade effect: Minting efficiency is higher]

[Consumable materials: copper, silver, gold, mithril, purple gold, coal, fire magic stone, etc.]

"Sure enough, it is a building that can cast ordinary metal into currency."

Lu Yun was secretly happy because this meant that he would have the right to mint coins from now on.

As long as the relevant metal is available, the relevant currency can be produced.

This is important.

Because the entire Black Turtle world only recognizes standard Black Turtle coins.

It's not a standard coin, and even the natives of the Black Turtle Realm don't recognize it.

At the same time, you cannot recruit bugbears, golden beasts, etc. with gold.

Don't recognize it.

Can only be recruited with standard gold coins.

So in this way, one can imagine how important it is to have this mint.

All copper, silver, gold, etc. can be minted into regular gold coins.

Lu Yun thought that the construction cost of this building was quite expensive, and the construction time was quite long, taking three days.

So let’s wait and let Luban build it.

It saves time and a lot of resources.

Then, he couldn’t wait to take out the reward [Gold Mine Vein].

Literally speaking, this is a gold mine given to Lu Yun as a reward!

View this object's data panel.

There is no detailed data, just a few lines of introduction.

[This gold vein is of high quality and can produce a lot of gold every day. 】

[Its duration is up to one month. So please try to mine as much as possible within a month. It will disappear automatically after a month. 】

[You cannot place this mineral vein on the black turtle. You must find an island, or a piece of land, to successfully place this vein and mine it. 】 Lu Yun immediately selected this vein and saw a large illusory vein.

That’s the vein of the gold mine.

But everything is red and it says it cannot be placed.

"Sure enough, you can't place a mineral vein on the back of the black turtle."

Lu Yun secretly pondered: "If I were asked to find a piece of land to place this mine, wouldn't I have to stay there for a month? "

After all, the veins can only last for a month before disappearing on their own.

Of course, Lu Yun must make good use of this month and collect as much as possible.

As a result, I will be trapped in one place for a full month.

Lu Yun didn't want this.

Then, an idea struck.

I thought, all I need is a piece of land.

Can I go to the World of Heavenly Books?

With this thought in mind, Lu Yun immediately opened the portal to the Heavenly Book World and entered the Heavenly Book World.

Select the gold mine vein again, and it really all turns green.

That means it can be placed!

Lu Yun knew that mining ore veins would destroy the environment.

In this world of books, the environment is so beautiful.

It would be a shame if it were destroyed.

So he stayed away from the river, went far away, found a remote flat land, and placed the metal veins.

Then, he ordered all the hard workers to start working.

No matter how many gold mines were dug out this month, they all belong to Lu Yun.

Of course, the more you dig, the better.

Lu Yun has become more understanding since he got the [Golden War Beast House].

This gold coin from the Black Turtle Realm has so many uses!

No matter how many gold coins you have, it's not enough.

So Lu Yun is now very focused on grabbing more gold coins.

At this point, a treasure chest has been completely arranged.

Lu Yun then continued to open the treasure box.

Soon, the remaining three treasure chests were all opened by him.

All the supplies obtained are as follows:

[You got purple gold coins x 500,000]

[You obtained “oo? Fertile soil” X1 million catties]

[You have obtained 10,000 True Essence Pills xl]

[You obtain the Zhenqi Gong method "Hunyuan Gong\
