……

The value of the materials can be seen in the names of the materials alone, which have not been seen before.

The blackiron alloy is a synthesis of three pieces of darkiron, but Su Yu's previous darkiron has been used in the monster farming tower, and there is nothing left in the warehouse, so she went to the monster spawner to remove three locks, and then replaced them with nine locks of silver-iron alloy.

Silver-iron alloy is literally, the alloy material made of silver and iron, the strength is several grades worse than that of Xuantie, but because the quantity has tripled, the effect is also similar.

The silver alloy is the same as the material synthesized from three silver ingots, and a hundred silver alloys are three hundred silver ingots, but Su Yu took a lot of gold, silver, iron and copper material ores when he received the system reward before, so three hundred silver ingots are still more than enough.

The last two materials are most noteworthy.

Colored pebble bricks are synthesized from seven pebbles of different colors, that is, seven stones are combined into one brick, and five hundred bricks are three thousand five hundred stones.

If it is an ordinary stone, let alone three thousand five, thirty-five thousand Su grapefruit can also be taken out, but this colored pebble brick must be synthesized with special colored pebbles, and this kind of pebble can only be collected by the sea, and the number is extremely small.

Because 500 pebbles of each color need to be collected, but pebbles of two colors are very rare, so the actual number of pebbles collected is far more than 3,500.

In short, Su Yu deliberately asked people to go to the beach to collect for a long time, and only then did he collect the materials of these five hundred colored pebble bricks.

As for the last glazed crystal stone, it is even more amazing, although the name has a 'stone', but in fact it does not match the stone at all, because this glazed crystal stone is actually synthesized with gemstone fragments.

Gem fragments are the product of failed gem setting and may seem useless, but when there are enough gem fragments, they can be used to recraft gemstones.

And because the gems synthesized from gem fragments are random, there is a very small probability that the best gems can be synthesized.

So at that time, some people even deliberately bought a bunch of junk gems, and then recruited a bunch of people who didn't know how to set gems casually, so as to obtain gem fragments, and then use the fragments to synthesize the best gems......

A glazed crystal stone requires ten gem fragments, and a synthetic gem requires ten gem fragments, which is equivalent to using a hundred gems to build this building, which can be said to be not simple at all.

In addition to the huge cost of building the Material Exchange Station, its function is actually not that powerful, because the system will charge a 'handling fee' for the exchange of materials using the Material Exchange Station.

It's just that the handling fee here is not money, but materials.

……

A minute passed quickly, and Su Yu came to the material exchange station, opened the material exchange panel, and saw the familiar exchange ratio.

Although stone is extremely rare in the early game, it seems that stone and wood should be materials of the same price, but if you want to exchange wood for stone, it is two wood for one stone, and the value is directly cut in half.

Similarly, the ratio of stone to wood is also two to one.

This is not the case for the lowest-level materials, not to mention the top-level things like dragon bones and elf spring water.

It is no exaggeration to say that if Su Yu sells the materials consumed to exchange for a bottle of elf spring water at the material exchange station, and then uses the money earned from selling the materials to go to the elf clan to buy elf spring water, he can buy at least five bottles!

This is still when Su Yu doesn't consider her current favorability bonus with the elves...... If you even take into account the favorability factor, then at least two more bottles will have to be added.

So although the material exchange station is easy to use, the pit is also a real pit.

Doubling pit for primary materials, triple pit for intermediate materials, five-fold pit for advanced materials, and top material ...... That's more than a dozen times the price, or even higher.

But none of this has anything to do with what Su Yu is going to do now.

Because these are the situations mentioned before that will only be encountered by exchanging low-level materials for high-level materials, but what Su Yu has to do is the opposite, she wants to use higher-grade materials for lower-grade materials.

After all, what she wants to exchange is just materials to upgrade the building, and it's not a good thing.

As for what to exchange for...... That is, of course, the pile of beast materials in the warehouse.

Although Su Yu's exchange of high-grade materials for low-level materials will definitely not be like the system, which can double the value of materials, this ratio will at least not suffer a loss, and may even make a small profit.

Because the method of calculating the value of materials at this material exchange station is based on the quality level of the material itself.

In other words, a slightly flawed blue skin and a complete blue skin, because the quality is equal, the materials they can exchange for in the material exchange station are also equal, and the value is calculated according to the value of the full hide, not the value of the flawed hide.

But if you take it out and sell it, it will definitely be that the value of the former will be lower, so the correct way to open the building of the material exchange station is to exchange high-grade defective materials for low-level demand materials!

Su Yu took out all the defective materials and exchanged them for a large number of building materials, and then used them to upgrade the buildings in the territory.

Originally, this kind of thing was left to Ain, which not only saved time, but also reduced material consumption, but because they had been very busy recently, Su Yu didn't add any more burden to them.

Upgrade all upgradable normal buildings in your province to level 6.

Most of the level 6 buildings take twenty-four hours to upgrade, and some special buildings take longer to upgrade, starting at least three days.

One day of upgrading is not a long time, but three days and five days is definitely too long, so these special buildings were left by Su Yu and handed over to Ain to upgrade when the time came.

Just because the source of pollution has been solved, although there will still be beast tides from tomorrow, the frequency and number of beast tides and the intensity of attacks will be greatly reduced, so Ain's side will also be more leisurely.

When the time comes, it is just right for them to be busy with the things that are upgraded, so that there will be no work to do.

Although the construction team is paid when it is not working, Su Yu can't give money for nothing, so the salary when there is no task is about one-third of what it is on weekdays.

However, they themselves will occasionally take on some private work, and without affecting the progress of the construction tasks she has assigned, Su Yu does not limit these, so the construction team is definitely a good job in the territory, no worse than the guards.
