It's completely dark now, and after night falls, the wilderness will become even more dangerous and unfamiliar.

There are many powerful monsters that like to hunt at night.

Leaving the territory now will lead to death!

They now have a deep understanding of what it means to have a moment of pleasure, the whole family crematorium!

Challenge mission is imminent.

Everyone had no choice but to grit their teeth and exchange for meat.

The remaining resources cannot be used to immediately increase combat power. In this case, there is no need to use them all in exchange for meat, recruit militiamen, and increase combat power in order to complete the challenge mission!

This time, no one dared to complain at all and obediently exchanged their resources for meat.

Don't look at the lords in nearby channels who often cry about poverty. Only they themselves know how much wealth they have.

Challenging tasks is related to their lives, so they must ensure that nothing goes wrong!

Ten thousand units of food were simply not enough, and they were quickly exchanged.

Seeing this, Lu Tong directly put another 30,000 units of beef on the shelves.

For some people, because they have just upgraded their main city, not only the difficulty of the tasks has increased a lot, but the resources are also gone.

In desperation, I could only take out the treasured drawings and trade them.

"Boss Lu Tong, I have no resources, can I exchange them with drawings?"

"Drawings? Of course!" After hearing this, Lu Tong became interested and asked:

"What kind of blueprint is it? Send it up first and take a look. I will decide how much meat I will use to exchange it with you!"

The other party directly hung up the drawings.

[White Item Drawing-Quilt]

Regarding blueprints, Lu Tong always accepted everyone who came and traded ten units of food to get the quilt blueprints.

Seeing someone exchange blueprints for food, everyone also took out their own blueprints to trade with Lu Tong.

For a time, Lu Tong gained a lot.

[White Item Drawing-Wooden Box]

[Green Item Drawing-Magic Stone Lamp]

[White Item Drawing-Wood Board]

[White Armor Drawing-Animal Skin Coat]

[Architectural drawings of first-level breeding farms]

…

A total of more than twenty drawings were traded this time, most of which were of white quality, and only two were of green quality.

Most of the types of these drawings are drawings of ordinary daily necessities, and there is no drawing of weapons.

But these are not the point.

The point is, among those who use blueprints to trade, some actually have blueprints for [Stone Bricks]!

The main city and other buildings in the Lutong territory cannot be upgraded because they do not have the synthetic material of stone bricks.

As a result, Lu Tong's territory cannot be expanded.

He also asked on nearby channels to see if anyone had the [Stone Bricks] blueprints and he was willing to pay a high price to buy them, but no one responded to him at that time.

Stone bricks will be a material that will be frequently needed in the future, and most buildings will require stone bricks.

Even though the price offered by Lu Tong was very attractive at that time, no one would trade the [Stone Brick] blueprint.

If it weren't for the sudden challenge mission, it would pose a threat to many weak lords.

I believe that Lu Tong may not be able to collect the [Stone Bricks] drawings in a short period of time.

Obtain the [Stone Brick] blueprint, and Lu Tong opens the information.

[Level 4 main city: wood x5000, stone bricks x5000, granite x500, leather x300, sand x100, iron x100]

Lutong now only needs one material, granite, to upgrade its main city.

Granite is not a precious material and can be found everywhere in general mines.

In the nearby channel, there are several lords whose territories are near the open-pit mine, and they should have granite resources in their hands.

Lu Tong posted a trading link on the channel, exchanging meat for granite, and one unit of meat was exchanged for 20 units of granite.

In an instant, I exchanged 2,000 units of Huanggang Rock.

With these materials, Lu Tong can finally upgrade the main city!

He first synthesized five thousand units of stone bricks. Two units of stone can be synthesized into one unit of stone bricks.

After gathering all the building materials, Lu Tong clicked on the Book of Lords to confirm construction.

Lu Tong's cabin was shrouded in a dazzling light.

After waiting for almost thirty minutes, the light slowly dissipated.

A new and solid rock fortress appeared in front of Lu Tong.

[Level 4 Simple Stone House (Main City)]

【Population:130/400】

[Storage: 10000/50000]

After the upgrade, the area of ​​the main city has become larger, and the original wooden buildings have all been replaced by stone buildings. The simple stone houses have a delicate and strong structure, and they are somewhat like a castle.

Inside the house, one room is divided into five rooms.

As soon as you enter the door, the largest room is the living room, with the kitchen and dining room on the left, and a bathroom on the right. There is a slightly larger bedroom further inside.

If you want to upgrade the main city next, you will need two synthetic resources, hardwood board and colored glaze.

Unfortunately, the drawings just traded with Lutong include drawings of wooden boards, but not hardwood boards.

As for the synthetic material Liuli, Lu Tong had never even heard of it.

Only when you find the hardwood planks and glazed blueprints can you upgrade the main city.

After upgrading the main city, Lu Tong's territory has expanded a lot.

In addition to the main city, there are many buildings he wants to upgrade.

[Level 4 warehouse: wood x5000, stone bricks x1000, sand x500, leather x100, iron block x100, straw rope x50]
