Survival: What kind of unscrupulous businessman is this? He is obviously a kind person.

The good news is that Su Bai knows what to collect.

The bad news is...

This thing is probably rarely sold!

For example, the gold blueprint!

If Liu Wei hadn't snatched it from Zheng Bailin, the other party would have kept it for himself!

For example, Liu Wei...

Would rather live in the initial small shabby house, but also want to hold back a big one!

If Su Bai hadn't used his talent to plunder and take away all the other party's items at that time, according to the number of high-level resources that appeared in the past few days, Liu Wei might have succeeded.

Unfortunately, there is no if.

"Let's save enough resources first!"

Su Bai didn't plan to buy it immediately. After all, the ranking list had just ended, and few people were willing to sell good things.

Precious items like the gold blueprint can only be tried during the beast tide.

"Maybe I should expand the scale of mortgage purchases!"

"What if someone is willing to mortgage?"

Thinking for a moment.

Su Bai returned to the shelter, walked up the stairs to the second floor, and looked at the empty surroundings.

Opening the construction page of the shelter, relevant information slowly emerged.

External facilities that can be built: [Pharmacy], [Arrow Tower], [Livestock Pen], [Lighthouse], [Mines].

Internal facilities that can be built: [Design Room], [Well], [Gym], [Energy Room], [Basement].

"Wow, so many?"

Su Bai checked them one by one.

Several of the internal facilities looked familiar.

[Well] seems to be an upgraded version of [Water Cellar], and the stone and soil consumed have also doubled.

[Basement] should be an upgraded version of [Cell], and it also has the function of storing food.

Of course.

The survival world is now covered with ice and snow, so there is basically no need to worry about food storage.

[Energy Room] is connected to the fireplace, which can provide more efficient steam for floor heating, toilets, screeners and refiners.

[Gym] has a large space, and can also consume energy to build equipment for exercise.

The last [Design Room] is the real surprise.

[Design Room]: Shelter facilities, which can be analyzed and designed by building a design room. The specific effect depends on the level of the design room and the level of the item.

"Sure enough, shelter is always the most important!"

Su Bai was filled with emotion.

With the design room, he could put those rare equipment into it to analyze the drawings, and then let Hu Sandao mass produce and sell them.

As for the profit...

The crazy bidding at the weapon auction is enough to prove it!

"Build, must build!"

Su Bai looked at the requirements, the lowest F-level does not require many materials.

But C-level requires at least 1 silver, 1 bronze, 50 stone, 50 wood, 50 soil.

B-level is even more exaggerated, requiring 1 gold, 5 silver, 5 bronze, 50 wood, 50 stone, 50 soil.

"Gold!"

"It seems that we have to wait until we kill the Frost Giant Wolf before we can build it!"

"And I don't have any B-level materials!"

Li Dalong and Zheng Bailin helped him get the B-level resource card and got 100 units of B-level wood, and then Su Bai upgraded the workbench.

But with the filter and refiner, it's only a matter of time to save enough materials!

What's more, after dealing with the Frost Wolf, there is a guaranteed gold treasure chest, and you may get new resource cards at that time.

"Let's take a look at the external facilities first!"

Su Bai looked at the other options.

Among the 5 external buildings, the function of [Pharmacy] is similar to that of the Design Studio, and it can also analyze drugs to obtain formulas.

[Livestock Pen] is similar to [Animal Stable], and can raise domesticated livestock.

The more special ones are...

[Arrow Tower], [Lighthouse] and [Mineral Deposits].

[Arrow Tower]: Shelter building, you can build one or more towers that can launch arrows to attack the designated area. The specific effect depends on the building level, energy stone grade, and arrow grade.

It's obvious.

This thing also needs to be driven by energy stones, and the preciousness of fire stones is becoming more and more obvious.

However...

Since there is such a specialty in District 10086, will District 9527 also have similar energy stones?

[Lighthouse]: Shelter building, you can build a lighthouse that can be used for lighting, and illuminate and heat the designated room through light refraction. The effect depends on the building level and the grade of the energy stone.

[Mineral Deposit]: Shelter facility, you can artificially design a mineral deposit, and artificially manufacture stone, ore, energy stone and other items. The specific effect depends on the grade of the core energy stone.

"Hiss~~~"

Su Bai was completely stunned.

All three buildings are related to energy stones.

The last [Mineral Deposit] can simply manufacture energy stones!

"Core Energy Stone?"

Su Bai looked at the item bar thoughtfully.

The B-level resource card gave him 4 thunder spirit stones, and he also had a B-level fire stone in his hand... Should they all be used?

"Try it!"

Su Bai decisively clicked to build.

F-level wood -100, stone -100, soil -100.

The white light dissipated.

A 1 square meter stone road appeared in the golden area.

There was also a groove in the center, the size of which was just equal to the fire stone and thunder spirit stone.

Take out a Thunder Spirit Stone and put it in, and the properties of the [Mineral Deposit] will change accordingly...

[Mineral Deposit]: F-level shelter facility, which can consume certain resources to transform into energy items.

Current core: B-level Thunder Spirit Stone.

Production rate: F-level lightning wood +5 per hour.

"Can only produce F-level?"

Su Bai frowned, rebuilt an E-level [mine], and took out the fire stone and put it in.

[Mine]: E-level shelter facilities, which can consume certain resources to transform energy items.

Current core: B-level fire stone.

Production rate: E-level fire stone +5 per hour.

Total number that can be manufactured: 1000.

Compared with F-level mines, E-level mines are obviously more effective...but this thing has a total number!

Although it sounds cost-effective to exchange 1 B-level fire stone for 1000 E-level fire stones, Su Bai is not going to do it.

After all, B-level fire stone is the strongest energy stone that the Fire Spirit Crossbow can currently use.

This is related to today's Frost Giant Wolf and Golden Treasure Chest!

"We can build a few more F-class mines, and then put the thunder spirit stones in first!"

"When the number of thunder-struck wood increases, we will use the screener to decompose it and the refiner to re-melt it!"

After a little thought, Su Bai began to build one by one.

4 F-class mines.

20 units of F-class thunder-struck wood can be produced per hour. It should be noted that... the wood consumed by the mine must be replenished every once in a while, otherwise it will stop running.

This is not a big deal for Su Bai at all, after all, he only needs to set the effect of the automatic loader.

In addition to these.

Su Bai also looked at the E-class mines.

Among the many items he had acquired before, there were several C-class [Iron Core Stones] with unknown uses. Although they were marked as energy stones, Su Bai had never found a use for them.

[Iron Core Stone]: C-class item, a special energy stone.

Now it seems...

Could this thing be used to make ore?

As expected, after putting the [iron core stone] into the E-level [ore deposit], the total number of ore deposits produced became 100.

"Each iron core can be exchanged for 100 E-level ores?"

Su Bai was very satisfied.

Although it is C-level, the iron core is useless in hand. Su Bai also asked in the regional channel, and did not see any equipment manufacturing that needs this thing!

In this case, it is better to convert it into E-level ore... After all, the ore he purchased from District 10086 is almost used up, and the number of iron boxes is not much.

The most important thing is...

F-level ore can be smelted into E-level iron blocks.

So can E-level ore be smelted into D-level steel?

If D-level materials are used to make weapons and equipment...C-level weapons, let me ask you how much money you are willing to pay for it!
