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

"E-grade pickaxe, only 35 stones?"

Su Bai's message shocked District 10086.

After all...

Just now everyone was discussing 'Boss Su'!

Su Bai had previously thrown out countless wood to buy iron boxes, and then suddenly fell silent, causing everyone to talk about it.

Unexpectedly, as soon as he turned his head, the other party threw out a bunch of E-grade pickaxes!

"How is this possible?"

Liu Yunjie looked at the furnace that had been built not long ago: "The smelting speed of F-grade ore starts at least 5 hours, and E-grade must be longer... How did he make so many E-grade tools?"

"Abandoned iron boxes?"

"Yes! That thing is also E-grade!"

"Does the abandoned iron boxes not need to be smelted, and can directly make equipment?"

"Damn! Sold at a loss!"

Not to mention the reactions of Liu Yunjie and others.

At this moment, the reactions of many survivors in District 10086 are actually similar to those in District 9527!

That is... saved!

Because of the broken stone axes and stone pickaxes, many people have completely lost the means of mining, which has directly led to the rise of various mining equipment!

Just now, someone sold the extra stone pickaxes in his hand for a sky-high price of 15 stones!

What about now?

E-level iron pickaxes only need 35 stones!

You can even trade with fire stones and abandoned iron boxes!

What a good man!

Is this boss Su sent by God to save the suffering?

"Brother, I want it!"

Someone decisively issued a transaction and threw out 10 fire stones and 15 stones without saying a word.

"Brother, leave one for me!"

Someone also took out the black iron treasure box and put all his wealth together to start the transaction.

There is no way not to change. His stone pickaxe has been broken. He can't just stare at it all day, right?

"Brother, can you give it a discount?"

Someone also tried to bargain: "I don't have enough stones on me, and there are not many fire stones left... How about I give you 5 stones first, and pay the rest slowly?"

"Go!"

Su Bai directly blocked the other party.

What? Want to take advantage of Su's labor for free?

Maybe it's because the quantity is scarce.

It took Su Bai only 5 minutes to sell all 40 pickaxes.

Glancing at the remaining time of the cross-zone talent, Su Bai was surprised to find that it had risen to more than 50 minutes!

When he sold wood in large quantities before, it could only increase by a few seconds each time, and it was not a loss overall...

But now, he adds at least half a minute to each transaction!

Sure enough, the higher the price difference, the better the effect!

Glancing at the private chat that had exploded, Su Bai directly exited the 10086 zone.

He had to count the harvest!

The pickaxe harvest was good, including 120 fire stones, 20 iron boxes, and the rest were 550 stone and 260 soil.

The materials received by the iron saw were 690 wood, 390 soil and 13 iron boxes, and 10 iron saws went through the "mortgage purchase" mode, and there will be 300 materials in the future.

As a result, the wood that was originally only three or four hundred pieces has once again exceeded the 1,000 mark, the number of stones has also soared to 700, and even the soil that was originally used up has now soared to 650 units!

There are also a lot of blueprints and equipment.

"Let's take a look at the D-level formula first!"

[Physical strength potion]: A D-level formula that can mix specific medicinal materials to make a physical strength potion, which can restore a certain amount of physical strength after consumption. Requirements: Pharmaceutical items, dragon root grass, deer whip grass, tiger yang grass, cow ding grass, etc., can be selected.

[Nutritional potion]: A D-level formula that can mix specific medicinal materials to make a nutritional potion, which can enhance the speed of nutrient absorption after consumption. Requirements: Pharmaceutical items, gluttonous grass*1, wild hawthorn*2.

There is no doubt.

These two formulas are very important to him, but it is probably not easy to make them.

Su Bai asked in two regional channels, and no one answered what the "pharmaceutical items" are... Either everyone hasn't got them yet, or they are held in their hands and are unwilling to sell!

But this time he got several E-level and F-level drug formulas.

It is estimated that these people have secretly tried it, and they are willing to sell it because they found that they cannot make it.

"Let's buy some medicinal materials first?"

"By the way, ask the rubber used to make toilets..."

After thinking about it.

Su Bai sent a message to Yu Jian, asking him to help buy it.

His contract with Yu Jian has not expired yet, so he is not afraid that the other party will conceal or deduct.

After returning Zhao Heng's 100 soil, Su Bai took out a few drawings and prepared to strengthen the defense of the shelter.

[City Wall], [City Gate], [Heavy Crossbow].

Two D-level and one E-level.

[City Wall]: D-level building drawings, you can use additional resources to gradually upgrade the wall to a city wall, and the specific effect depends on the materials used. Requirement: At least 200 stones of any quality are required each time.

[City Gate]: D-level building drawings, you can build a city gate that can be gradually reinforced at the gap in the wall, and the specific effect depends on the materials used. Requirements: 100 wood per enhancement.

[Heavy Crossbow]: E-level weapon, you can build an immovable heavy crossbow in the shelter and inflict heavy damage to the target! The effect depends on the distance of the target. Requirements: 20 E-level wood, 10 E-level iron blocks, 1 E-level tendon. Each launch consumes 1 wood and 1 iron block.

"Tendon?"

"Qin Xueer must have it!"

Not long after opening the private chat, Su Bai got a D-level tiger tendon.

Perhaps the other party was busy killing monsters, so he didn't mention the price at all, and only said that he would talk about it in the evening.

There was nothing to say, so Su Bai directly placed the heavy crossbow on the window.

"Sure enough!"

"Abandoned iron boxes can be used directly as iron blocks!"

"But the premise is that there must be a casting table... I can smash this thing flat enough!"

After trying the operation of the heavy crossbow, Su Bai walked out of the shelter.

Stone -200.

Wood, -100.

A flash of white light passed by.

A circular city wall with a height of 3 meters and a diameter of 10 meters came into view, but the thickness was only a dozen centimeters... Su Bai was worried that it would be directly broken by the giant wolf!

[City Wall]: F-level building, can consume 200 arbitrary stones for reinforcement, up to D-level.

[City Gate]: E-level building, can consume 100 arbitrary wood for reinforcement, up to D-level.

"E-level?"

Su Bai's eyes lit up.

So, these two buildings can be improved by stacking low-level resources?

If the brother who sells blueprints knew, would he faint in the bathroom?

Oh...

No one has a bathroom yet! That's fine!

"Reinforce it more!"

Su Bai glanced at the remaining resources and directly reinforced the city wall twice and the city gate four times.

The city wall was finally upgraded to E-level, the height increased to four or five meters, and the thickness was more than doubled to about sixty centimeters.

The city gate directly entered D-level, half a meter thick, Su Bai didn't know if it could be opened after closing... But no matter what, it looks safe!

No other meaning!

Because the furnace is exactly two hours each time, the time for the last batch of steel to be smelted is exactly the time when the safe zone is closed.

Su Bai plans to reinforce both the [city wall] and [city gate], which can at least stop the giant wolf for a few seconds, giving him a chance to take away the molten iron.

"It seems that we need to make more iron pickaxes to exchange for stone materials, and raise the city wall as soon as possible!"

"Level 2 shelters can also upgrade wooden fences to wooden spike fences... I wonder if they can be built on the city wall?"

Thinking.

The second batch of molten iron in the F-level furnace has been smelted.

Su Bai also participated in the tense and exciting iron-making process, and an iron saw or iron pickaxe was born every 10 seconds!

Don't ask why it can be so fast...

It's nothing, just practice!
