Demon Blood Pool at the beginning: My troops are getting more and more.

In the Devil's Castle warehouse.

[Timber: 1.51 million units.] [

Stone: 1,580,000 units.] [

Crystal nucleus: 385 pieces.] [

Magic Crystals: 9 pieces.] Lin

Feng chose to upgrade the castle to level 10 first.

Then make a power-enhancing scroll.

After all, after the castle is upgraded, maybe some new features will come out.

[Do you want to upgrade the castle?

] [Yes/No?

] [Upgrade!] [

Consumes 500,000 units of wood and 500,000 units of stone.

[Congratulations to Lord Lord, for raising Castlevania to level 9.] It's

still the same white light.

Lin Feng forcibly opened his eyes with his thumb and forefinger this time.

Through the gaps in the white light in the air,

only a humanoid silhouette could still be seen.

In desperation, I had no choice but to give up.

[Continue to upgrade!] [Dudu Dudu!!

] [There are not enough materials, so I can't upgrade!]

"Well, I calculated that it should be enough!" "

Could it be that upgrading from level 9 to level 10 is not progressive, but doubled?"

With

questions, Lin Feng clicked on the attribute list of his castle.

【Castlevania. [

Level: LV9.] [

Population: 484/950]

[Castle Core Health: 800K (Invincible). 【

Territorial Range:9000m】

【Function: Within the territory, the lord has the ability to discover, decompose, and collect the warehouse. [

Normal buildings: warehouses, communicators, crafting tables.] 【

Special Buildings: Demon Blood Pool, Portal, Connecting Crystals.】 [

Upgrade required: 1 million units of wood, 1 million units of stone, and 2,000 units of fine iron.] [

Faction: None.] After

reading the list of attributes, Lin Feng suddenly realized.

It's not that there aren't enough wood and stones, it's that the castle has been upgraded from level 9 to level 10, and a new material, fine iron, is needed.

But fine iron has never been seen in the trading market.

Even the collected information does not mention it.

Listen to the name, it should be a metal.

We'll have to wait to see if we can exchange some quality food for some.

With regret, Lin Feng came to the production table.

Prepare to craft a power-boosting scroll.

The 3,000 units of scorpion tail that I just bought in exchange, plus the wolf's fangs and cat's claws in the warehouse.

Enough to produce 3,000 power-enhancing scrolls.

Lin Feng started to operate on the light curtain on the production table.

[Consumes 30,000 units of wolf teeth and 1 cat's claw.] 50,000 units, 3,000 units of scorpion tail. [

Obtain 3,000 power-boosting scrolls.] The

materials in the warehouse disappear instantly.

3,000 power-enhancing scrolls appear in the corner of the warehouse.

【Strength Enhancement Scroll.】 [

Beginner limited-time item.] [

After use, increase the lord and his 18 power for 10 minutes.]

[It can be reused, time is stacked, but the effect is not stacked!]

Lin Feng finished reading the attributes of the power enhancement scroll.

The heart is shrinking.

10 minutes attribute 18 points, this is also too perverted.

Although it didn't last long.

Lords like him who have a demigod class or higher have limited promotion.

However, it has a miraculous effect on the lords of the ordinary and elite classes.

Even the lord of the command class will have a huge boost.

A full 18 points of strength increase.

For the normal class, this is equivalent to a 9-level streak.

As for the lords with ordinary troops, the current population is almost more than 18.

All of them are increased by 18 points, and even if it is only for 10 minutes, you can kill all monsters within a 500-meter radius of the castle.

Thinking of this, Lin Feng began to calculate.

After all, he was called a profiteer by many lords for a long time.

I can't let them down.

According to calculations, a monster within 500 meters can obtain about 600 units of high-quality food.

For the other lords, 500 units of food should be fine.

In a 1 to 3 ratio.

That is, use a single power to enhance the gains of the scroll.

in 1500 units of base material.

And that's not even counting the experience of killing creeps, and the random drop of crystal nuclei.

After the calculation, Lin Feng immediately sent a message on the trading channel.

[Sell Power Enhancement Scrolls!]

[Increase the strength of lords and classes by 18 points in 10 minutes.] [

1 scroll for 1000 units of base materials or crystal nuclei/magic crystals of the same value.] 【

Limited quantity, first-come, first-served.】 [

Another 5 units of high-quality food purchase 1 unit of refined iron, some friends, please directly designate me to trade.] Lin Feng's

information immediately aroused the interest of scalpers in the trading market.

Strength enhancement scroll, this thing is definitely a rigid need of the weak chicken lord!

However, there are not many people discussing it.

Even those in the know don't talk about it.

[The profiteer is worthy of being a profiteer, and this Nima sells for a scroll at a sky-high price. 1 1000 units, just grab it!]

[Poor ghost, Lin Feng's boss is not faster than robbing

money!Everyone hasn't forgotten the previous system announcement, right?The blueprint of this power enhancement scroll is definitely the Commander Wild Monster Explosion!

Just now he acquired another 3000 units of Scorpion Tail. It must be the ingredient for making a power-strengthening scroll.

Presumably, other materials are available in Lin Feng's warehouse. Robbery has this to make money?

] [Resist profiteers, start with me!] By the way, sell Musashi Kojiro brand high-quality food. The last 800 units, a ratio of 1 to 9. Clearance Sale!]

[Sold out!! This is a whopping 1,000 units. Could it be that all the lords are rich, and I am the only one who is poor!]

[Big brother, you are taught math by a physical education teacher! As long as you do some calculations, you will know that this transaction is sure to make a profit!

Not to mention that you can also gain experience. Lin Feng's boss is quite kind. I guess if he sells 1500 units, someone else buys it. 【

In Xia Shen Wansan, on behalf of the Wansan Chamber of Commerce to sell power enhancement scrolls. 1 x 1498 units of wood/stone.

There are only 2,500 sheets, and those who want to exchange them should act quickly, and there will be no such store in this village after that!

] [Profiteer!!]

Lin Feng finished putting the scroll on the shelves.

Just grilled a few crispy pork belly sticks with wood.

Wait until he's done eating.

The power-enhancing scrolls have been sold out.

Many scalpers have sniffed out the opportunity.

Among them, the Wansan Labor Union established by Shen Wansan almost covered all the 10,000 scrolls.

Lin Feng didn't care, he wasn't prepared to change the price anyway.

After posting an order to acquire 10,000 scorpion tails.

Prepare to delete the friend request as usual.

But when he opened his friends list, it was no longer empty.

[Su Datou. 【

Level 5.】

【Level 1 Slime House Lord.】 [

Population 2/30.]

[Strongest class: Demigod-level Force Slime. Lin

Feng immediately clicked on the chat window.

I saw that there was already a message from Su Datou inside.

[Little madman, support my brother to order wood and beg for a pot to raise!]

This Su Xiaopang finally found out how to add friends.

If it was a few days later, Lin Feng would be ready to burn yellow paper for him.

[Su Xiaopang, why don't you go to the trading market to change it if you don't have wood?]

After Lin Feng sent the message, he specially added a jitter function, for fear that the other party would not be able to see it.

Su Datou is sorting out the materials in the warehouse.

After all, Virgo can't tolerate a little sand in his eyes.

A message popped up in the curtain, and it shook in front of his eyes.

Su Datou didn't think much about it, and immediately clicked on it to check.

After reading the news, I burst into tears.

It's not because I'm excited to see my old friend, but because I'm crying stupidly.
