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

"Boss Su, can this silver blueprint be exchanged for a C-level saw?"

The private chat on the other side was still urging.

Su Bai thought for a while before slowly replying: "I'm sorry, brother, this thing has random attributes... If it gets a bad effect randomly, it will be a huge loss!"

"How about this, I still have weapons, equipment and D-level saws here, see if anyone is willing to exchange?"

After a conversation.

Su Bai exchanged a C-level snow boot and a D-level saw for the silver blueprint.

Is it a loss?

Maybe a little!

After all, the value of C-level equipment is equivalent to that of C-level tools in a sense!

But Su Bai knows how important high-level facilities are!

After all...

Isn't it because of the B-level workbench and C-level casting table that he can have a C-level saw today?

The question is, which facility should be upgraded?

Casting table?

Or workbench?

If it is a workbench... Su Bai can't get 10 times the B-level materials at present!

As for the casting table...

[Casting Table]: C-level shelter facility, can forge, repair, and upgrade weapons and tools, the effect depends on the materials used. Requires hammers, fire sources and other tools and facilities to assist!

Upgrade \u003e\u003e\u003e [Excellent Casting Table]: B-level facility, requires 1 gold, 1 silver, 50 steel ingots, 50B-level stone, 50B-level wood.

Upgrade \u003e\u003e\u003e [Lucky Casting Table]: C-level facility, requires 10 silver, 100 steel ingots, 500 units of C-level stone, 500 units of C-level wood, 1 silver blueprint.

Very good!

Su Bai cannot meet the two upgrade methods.

But in comparison, the lucky casting table obviously has a greater chance.

After all...

Steel ingots may be obtained through E-level iron blocks converted from "iron core stones", and C-level wood and stone can also be obtained through screeners and refiners.

The most important thing is that this thing can be received!

"Then..."

"Sell the goods quickly!"

Su Bai decisively sent a message in the regional channel, and the D-level iron saw was exchanged for C-level resources first.

For most survivors, they love and hate advanced resource cards...Everyone knows that they are good things, but they hate that they can't be used immediately!

Especially those who got 30 units of C-level resources!

It's useless to keep them, but it's a pity to throw them away, and it always feels too bad to exchange them for D-level saws...

However...

When Su Bai showed the C-level snow boots, all doubts disappeared completely.

More than 60 D-level saws, 4 snow boots, 2 crossbows, 3 giant wolf armors, 5 giant wolf wrist guards and 7 giant wolf leggings...

In total, more than 400 units of C-level wood, more than 300 units of C-level stone, more than 300 units of C-level soil, as well as 150 iron boxes and more than 10 copper boxes, as well as fertilizers, nutrient water, and tonic liquid were brought to Su Bai.

Including the remaining ones in Su Bai's hand, as well as the ones produced by the steam filter and refiner, his C-grade wood has reached more than 480.

"There are still 5 C-grade resource cards!"

Su Bai was excited.

When he traded just now, he was lucky to trigger two talent crits and get two extra resource cards.

And now, it depends on whether his luck is good enough!

"Come out!"

The first resource card was crushed, C-grade stone +50.

"Come again!"

C-grade stone, +40.

+30.

+30...

+100!

It should be said that the survival world always likes to give you a surprise at a critical moment.

The C-grade stone problem has been solved, and the C-grade wood only needs to wait patiently for the filter and refiner.

Now there are only silver and steel ingots.

"Qin Xueer must have an abandoned silver treasure chest!"

"As for the steel ingots..."

Su Bai looked at the [Mineral Deposits] in the golden safe zone.

It seems that the speed of obtaining E-level iron blocks must be accelerated... Anyway, what he needs least now is E-level resources!

7 E-level mines were built in succession, and Su Bai put all the [iron core stones] into them.

A total of 8 mines can obtain 40 E-level ores per hour.

For this reason.

Su Bai also deliberately dismantled all F-level furnaces and rebuilt 2 D-level furnaces and 3 E-level furnaces.

In this way, the number of furnaces becomes 4 D-level and 4 E-level.

If the E-level furnace can also smelt steel ingots, he can increase the number at any time...

"11 o'clock!"

Su Bai glanced at the time.

It has been 1 hour since the safe zone was opened, and he should plant the land well.

"Jiang Le, come to work!"

"Here I come!"

Jiang Le went online at the speed of light, curiously looking at everything in front of him.

The greenhouse was not upgraded, but Su Bai had just exchanged for a lot of soil, including more than 200 units of Class C [high-quality humus soil], which was just enough to build two Class C farmlands.

"Jiang Le!"

"Transplant the spirit tree here quickly!"

"I bought several bottles of tonic today. Can the spirit tree be upgraded?"

"I'll try!"

Jiang Le took the Class C medicine hoe and began to carefully dig the soil.

It took more than half an hour before he finally transplanted the spirit tree into the Class C farmland.

With the irrigation of bottles of tonic, the spirit tree, which was originally thin and long like a spirit boy, gradually became thicker.

"Almost done!"

Jiang Le felt something and hurriedly picked up the nutrient water and began to irrigate frantically.

A few minutes later.

The spirit tree, which was originally only as thick as a rolling pin, has become as thick as a bowl.

On its branches, five or six red fruits are hanging on the branches, and you can tell at a glance that it is definitely not an ordinary product.

[Thriving Spirit Tree]: D-level plant, can produce spirit fruit, which can temporarily increase the spirit attribute after eating, and become very energetic at the same time.

[Spirit Fruit]: D-level item, which can temporarily increase 6 points of mental power after eating.

[High-quality Spirit Fruit]: C-level item, which can temporarily increase 8 points of mental power after use, and there is a probability of gaining 2 points of spirit after multiple uses, which can be stacked.

"Perfect!"

Su Bai breathed a sigh of relief.

The strength of the spirit tree is beyond his understanding of E-level items.

After upgrading to D-level, the effect is even stronger!

Unfortunately...

The tonic liquid is a D-level item. If you want to go further, you may need enough C-level tonic liquid.

"A Le!"

Su Bai patted Jiang Le's shoulder: "We have nothing else to do today... You will focus on cultivating this spirit tree later. The more fruits, the better!"

"In addition, we will transplant other important medicinal materials to the C-level farmland. We can take our time with this matter. Don't worry!"

"When you are done, I will give you a big red envelope, plus a salary increase!"

"Don't worry, boss!"

Jiang Le was immediately full of energy and patted his chest: "Leave this to me, I guarantee it will be completed!"

20 minutes later.

Su Bai got 53 spirit fruits.

41 of them were D-level and 12 were C-level.

No need to say more.

Eat!

Not long after, all the C-level spirit fruits fell into his stomach.

Spirit, +8.

The original 11 points of mental power in the attribute panel directly soared to 19 points.

In addition to the short-term improvement of mental power by the spirit fruit, it is a full 27 points.

His current data is also luxurious!

Strength 22 (27), Constitution 19, Spirit 19 (28), Speed ​​19 (21).

This data.

It is close to the attributes of Qin Xueer before she opened the big one!

"Boss Su, the safe zone is about to open!"

Qin Xueer sent a message.

Glancing at the time, Su Bai stood up and looked at the quantum puppet next to him.

The four quantum puppets were already equipped, and the only A-level puppet was still being used by Jiang Le.

After saying something to Jiang Le, Su Bai took back the A-level puppet and then sent a message to Chen Ze, Zhang Sijie, and Zheng Bailin.

When it was 12 o'clock, Su Bai did not immediately let the others control the puppets, but moved the puppets outside the shelter while picking up the treasure chests left over from the beast tide last night.

10 minutes later, the five-man team went online together.

The first team-up to kill the BOSS in the survival world officially began!
