"Brother Leg, what should I do next? There are still two hours left for the first wave of monsters to attack the city, but I can't even get out of my room right now. ”

Zhang Yao hurriedly asked.

"Don't worry, that's one of the reasons I mentioned at the beginning that your situation isn't really that bad."

Cheng Shen opened the trading market and replied at the same time.

"I was just speculating at first, but the information you provided continued to confirm my thoughts.

The fact that the castle has patrolling guards, cooks, and habitable safe houses shows that it is not as chaotic as you might think, but has some kind of special operating rules.

It's just that this kind of rule may not be very friendly to ordinary people.

The monsters in the castle will follow the rules, so they won't let the monsters outside in easily.

It's even less likely that you'll be able to participate in a tower defense game before you take control of that castle.

And the items you get from the chests are an important proof of this.

The treasures we opened are basically materials, recruitment volumes, but yours is equipment.

So, the danger you will face will only come from inside the castle, and you don't have to worry about monsters attacking the city. ”

After speaking, Cheng Shen felt that these words were not rigorous enough, so he added a sentence.

"At least not worry about it now."

"I see."

Zhang Yao suddenly softened when he heard this, "Then I will be relieved!" Wait a while for the monsters to attack the city, and I'll just hide in the room and not go out! ”

“……”

Cheng Shen's thoughts paused for a moment.

He saw a transaction of exchanging wood for stone, the ratio was naturally 1:1, and both materials belonged to basic resources and would not be at a premium.

He had a total of 53 units of stone.

After building the Ice Arrow Tower, there are still 23 units left.

He replaced them with wood.

Repairing a fence requires 10 units of wood, repairing training stakes requires 5 units, and a campfire consumes wood on a continuous basis.

Timber is now much more important to him than stone.

Cheng Shen checked that the territory was surrounded by forests, and there were no towering mountains or obvious mineral veins.

In other words, he will definitely be short of stones in the future.

But relatively.

He was able to exchange stone with other lords with plenty of wood.

At this stage, the key is to make use of all the resources at hand and try to survive the monster siege.

And water.

There is only 1 unit of clean water in the territory, which is barely enough for him to consume for a day.

But Cheng Shen remembered that when he watched the World Channel before, there was a river directly near someone's birthplace, so there must be no shortage of water resources.

After searching for specific criteria, he found out that he was wrong.

Couldn't be more wrong.

Although some people start by guarding a river and a wheat field, the exchange price of food and water in the market is still ridiculously high.

Not every liege starts with food and water in resource packs.

Each person starts with only two loaves of bread and a bottle of water, which is barely enough for one person for a day.

Not to mention the fact that the demand doubled after recruiting a unit.

In the market, the price of a loaf of bread has reached the same value as an iron ingot!

The price of water is slightly lower and much more expensive than basic supplies.

Such prices are clearly unreasonable.

"Someone is trying to control the trading market......"

Cheng Shen saw the clue.

There must be a reason behind such a crazy food deal. If it was just the high price of food, he could understand it, but now there is even a shortage of water, and there is no other explanation than that someone is deliberately controlling sales.

Think for a moment.

And he understood.

No one can guarantee that you will be able to get food resources after the monsters attack the city.

This first batch of food and water is the most precious, once it is snatched up and cannot be replenished in the future, then the lord who has a large amount of food and water resources in the early stage must be a strange commodity and can exchange it for anything he wants.

Everyone has selfish intentions.

Including him, too.

Controlling the sale of water resources can help a lord accumulate a large amount of important resources in a short period of time, giving him more hope of survival.

But in fact, by squeezing the living space of others excessively in this way, to achieve the purpose of strengthening oneself, it is just a chronic suicide.

Even the capitalists know how to cut leeks in a sustainable way.

Pity.

Few people can see the long term.

However, at the moment, this trend does not seem to be serious.

The main thing is that the first wave of monsters hasn't appeared yet, and no one knows what the situation is here.

If the food problem is not alleviated after the first wave of monsters, then something will happen.

Cheng Shen thought a lot, but the resources in his hands were not enough for him to take precautions.

He just took out five pieces of bread and exchanged ten units of clean water.

Then I checked and found that I couldn't exchange good things, so I closed the market.

Before the first wave of monsters, it was impossible for anyone to take out the recruitment scrolls or architectural drawings to exchange for materials, and they all asked to exchange for the same items.

Only after the first wave of defense is completed will the trading market be enriched.

"You're wrong."

Cheng Shen replied at this time.

"I guess that the monsters in the castle must be much stronger than the previous waves of siege monsters, and even more than the first ten waves of monsters.

Even if you have the equipment, it's definitely not something you can handle at this stage.

The purpose of the system should be to allow you to face the monsters that are besieging the city and grow in battle.

If you choose to hide in your room, you will lose your chance to survive once the weakest first few waves of monsters are dealt with by the castle guards. ”

“…… Oh! I see, Leg! Isn't this just a game of fighting monsters and leveling up!

Brush up experience, level up, and explode equipment, this is my strength!

Wait for my good news, Brother Legs! ”

Zhang Yao seemed to have a sudden realization.

“…… Be careful. ”

Cheng Shen still has something to say.

He felt that there should be a lot to explore in the castle.

For example, the chef on the first floor.

The red room on the second floor.

Since that monster castle can always be maintained in a unique way, there must be some kind of special rules.

If Zhang Yao can figure out the rules, he will definitely be able to move in the castle more easily, and even master the castle.

But it's all based on the fact that he can survive.

As a stranger he had never met, Cheng Shen had given him enough help, and the next thing was to see his own creation.

[Do you want to build the Ice Arrow Tower?] 】

"Yes."

In the prompt sound of the system, Cheng Shen took out the construction materials and chose to use the drawings behind the wooden fence at the gate.

Thundered......!

The earth trembled.

The light emerged, and a three-meter-high cyan stone tower slowly rose from the ground, and the upper part of the arrow tower was a stone sculpture in the image of an archer, covered with pale hoarfrost, and even the surrounding temperature dropped a lot out of thin air.

The moment it was built, the icon of the arrow tower also appeared in the territory model in his mind.

Cheng Shen can freely control the arrow tower to attack any unit.

Its range enveloped the entire courtyard.

Therefore, even if a monster attacks from the side or rear, you don't have to worry about getting out of its attack range.

"The attack speed of 1.6 is almost one hit in two seconds, to be honest, it's still a little slower, after all, it's a secondary defense tower controlled by the main control......"

"But the first wave of monsters shouldn't be too strong."

Cheng Shen said in his heart.

The Ice Arrow Tower is also a rare-level defense tower, and even if it's not an output tower, it's not a problem to defend the first wave of monsters.

This point, Cheng Shen deduced from Zhang Yao.

Very simple.

Look at the attribute strength of his two pieces of equipment.

Combined, those two pieces of equipment are probably equivalent to the attributes of an Ice Arrow Tower, or even worse.

If the system thinks that it can survive at that level, the arrow tower will definitely be able to easily defend the first wave of monsters.

Of course.

He also had to make some preparations.

Wooden fence, fixed!

Cheng Shen chose to invest 10 units of wood.

The wooden fence surrounding the entire courtyard suddenly took on a new look in a white light.

【Wooden Fence】

【First Order】

[Level: Normal]

[Level: 1]

[Effect: The basic fortifications that protect the territory, no monster can invade your territory through the ground until the durability of the wooden fence is exhausted]

[Characteristic: None]

[Durability: 5000/5000]
