Chapter 507, New Functions of the Level 9 Northern Defense Fortress

"The second-level northern defense line has not changed much compared to the first level."

"Except for the increase in building durability."

"Also, the units produced and daily consumption have increased."

But these are nothing to Fang Yuan.

What he is most concerned about is the conditions for subsequent upgrades and whether there are new increases.

Fang Yuan pulled down the building panel.

Found the conditions for upgrading from level 2 to level 3.

[Upgrade conditions]: 1. 20 million gold coins, resources, 20 gold source crystals.

2. Obtain the title of Gondor's first warrior (completed)

2. Defeat a grassland orange army (completed).

Seeing the conditions for the upgrade.

Fang Yuan's eyes lit up.

"Actually!"

"So simple."

"And the upgrade conditions are different from the main city. Not all conditions will be refreshed, but a new condition will be added progressively."

"Only the first condition will change a little, increasing the consumption of gold source crystals, gold coins, and resources."

"But a mere 20 million gold coins and resources are just a drop in the bucket for me at the moment, not worth mentioning at all."

"The most important thing is that the newly added third condition is not difficult to complete, and it can even be said that it has been completed."

"Defeat the grassland orange army, I don't know how many I have defeated."

Fang Yuan couldn't help thinking at this time.

"It seems that even for golden buildings, the conditions for upgrading them will not be too difficult."

"Otherwise, it will not be upgraded at all."

"It's still a negative asset after it's taken down."

"That's just right, quickly upgrade the northern defense line."

"I can also mass-produce magic crystal cannons as soon as possible and attack Gondor as soon as possible."

After Fang Yuan made up his mind, he selected the upgrade option again.

"Ding, the upgrade is successful. You have obtained the third-level golden military fortress Northern Defense Line."

The upgrade to level three is not much different from the second level.

Fang Yuan directly pulled the panel of the Northern Fortress to the bottom.

Check the conditions for upgrading from level three to level four.

When he saw it, Fang Yuan's eyes showed surprise.

"It has been completed again!"

"This fourth condition is so simple."

[Upgrade conditions]: 1. 30 million gold coins, resources, 30 points of golden source crystals.

2. Obtain the title of Gondor's first warrior (completed)

3. Defeat a grassland orange army (completed).

4. Kill a grassland orange hero (completed).

The newly added fourth condition is just to kill an orange hero.

On the grassland, not to mention orange, even the golden sword master has been killed.

This condition naturally can't hold him back.

At the same time, Fang Yuan thought of it.

"If we extrapolate from this."

"Is it possible that I can complete all the conditions for subsequent upgrades?"

"The only condition that blocks me from upgrading the Northern Fortress to level nine may be the resources and golden source crystals in the first condition."

"And the gold coins and resources!"

"Although the loss is relatively large during transmission."

"But there are still billions."

"It's just level nine, which is enough to spend."

"It's this golden source crystal!"

"There are only 150 in total. I just upgraded to level three and have used up 30, leaving 120."

"If we extrapolate further, I can upgrade to level six at most, and then all the golden source crystals will be used up."

Fang Yuan didn't expect that the golden source crystals would still be the ones that blocked him later.

He shook his head helplessly.

"Forget it, let's use up the ones I have first and then think of other ways."

Fang Yuan chose a building and chose to upgrade.

"Ding, your golden building, the Northern Fortress, has been upgraded to level four."

After reaching level four, Fang Yuan saw that there were still 90 golden source crystals left in his hand.

The number of golden source crystals required to upgrade from level 4 to level 5 is 40.

It can still be upgraded to level 5.

Of course, the premise is that the fifth condition can be met.

Fang Yuan pulled down the panel to check the fifth upgrade condition.

[Upgrade Condition]: 1. 40 million gold coins, resources, 40 points of golden source crystals.

2. Omitted

3. Omitted

4. Omitted

5. Occupy more than 200 hectares of land on the grassland (completed)

Fang Yuan touched his chin.

"Only 200 hectares of land."

"Hehe."

"I have occupied all the land south of the river on the grassland."

"This condition is easily met."

"Continue to upgrade."

Along with the Lord's Seal, a message popped up.

The golden North Border Defense Fortress was upgraded to level 5.

When it comes to upgrading from level 5 to level 6.

The number of golden source crystals required is 50 points.

And the remaining golden source crystals in his hand are just enough to upgrade to level 6.

Since it can be upgraded, Fang Yuan will not hide it.

He pulled the panel to the sixth condition to check.

He smiled again after seeing it.

"Sure enough!"

"It's still completed!"

[Upgrade conditions]: 1. 50 million gold coins, resources, 50 gold source crystals.

2. Omitted

3. Omitted

4. Omitted

5. Omitted

6. Build a fortress on the grassland, the quality cannot be lower than orange, and it can withstand the attack of the orcs (completed)

To be honest.

It's really difficult to complete this sixth condition now.

First, you have to pull the orcs over to fight, and you have to be able to beat the orcs.

Change to other lords.

For this condition.

I'm afraid I can mobilize the entire alliance.

Then I have to hire thousands of lords from other countries.

Then I have to prepare for several months before I dare to take action.

Fortunately, I don't need it.

Before that, I had already taken action against the orcs on the grassland in advance.

Annihilated their main force heading south.

This condition was met in advance.

At the same time, Fang Yuan was also thankful.

This upgrade condition is based on his previous battle record.

Then Fang Yuan directly selected it and chose to upgrade again.

"Ding, the upgrade is successful, your Golden Northern Defense Fortress has been upgraded to level 6."

And it has reached level 6.

Fang Yuan also knew that upgrading to level 7 would be a long shot for the time being.

The main problem is the golden source crystal.

Now he really doesn't have any in his hand.

But Fang Yuan is still quite curious.

What is the seventh condition for this upgrade from level 6 to level 7.

He pulled down the fortress panel.

[Upgrade Conditions]: 1. 60 million gold coins, resources, 60 points of golden source crystals.

2. Omitted

3. Omitted

4. Omitted

5. Omitted

6. Omitted

7. Defeat a golden army on the grassland (completed)

When he saw the seventh condition.

Fang Yuan breathed a sigh of relief and said in a rather relaxed tone.

"It seems that all I need to do next is to gather all the golden source crystals."

"I can upgrade the level of the Northern Frontier Fortress to level nine."

"I didn't expect that upgrading the Northern Frontier Fortress is easier than upgrading the hero level."

"I was really careless in my previous ranking."

"The real ranking is to upgrade the Northern Frontier Fortress first, and then build a branch city."

"Finally, use the war in the south to upgrade the hero level of my subordinates."

"When the war is over, the output of the dragon breeding land may be high."

"I may be able to upgrade the hero level to the maximum."

"So now the Northern Frontier Defense has been fully upgraded."

"The next step should be to build a branch city."

"It's just the construction of the golden branch city!"

"It requires a lot of resources."

"The resources in my hands are a bit insufficient now."

"I'd better sell some spoils and replenish some resources."

Fang Yuan thought slightly and was about to teleport to the warehouse.

But at this time.

A message popped up on the Lord's Mark.

"Ding, a caravan has entered the trade market, and the other party is requesting a trade."

Fang Yuan's face lit up when he heard the news.

"I didn't expect that a target customer would arrive so soon."

"Just right, I'll get the golden source crystal first and upgrade the Northern Fortress to level nine in one go!"

Fang Yuan immediately opened the trade market panel.

Check the name of the caravan that came to trade with him this time.

"The caravan of Ye Ao. Nai Wo He."

Seeing the name of the caravan.

Fang Yuan's face twitched slightly.

"This name!"

Fang Yuan thought of the Samat family in the parallel world Blue Star.

"A lord who can give a caravan such a name."

"Either 250 or really powerful."

"But I prefer the former."

"Of course, it is possible that both are possible."

"Try it out first, if it is a pure 250."

"Just block it."

Just when Fang Yuan was thinking about it.

The message of Ye Ao Nai Wo He popped up.

"Name your price!"

"I'll take them all."

"Don't question my strength."

"I have everything you want!"

Seeing this message.

Fang Yuan was too lazy to think about it and left a message directly.

"300 golden source crystals, no matter what the attribute is."

This price seemed very high to Fang Yuan.

Normal people would not agree to such a price.

And Fang Yuan also traded with the mentality of asking for a high price and paying it back on the ground.

Just wait for the other party to bargain.

Fang Yuan's bottom price was 210 golden source crystals.

These source crystals just happened to upgrade the North Border Defense Fortress to level nine.

If the other party felt that 210 was too expensive, he could just buy some other items.

But Fang Yuan had calculated so much.

He just didn't expect that the other party would agree to this deal.

"Deal!"

When he saw these two words, Fang Yuan was a little confused.

And then the trade market popped up a message.

"Ding, the transaction was successful, you got 300 gold source crystals."

Along with this prompt sound, there was a new message.

"You are very good."

"I, the Night Watch family, have high hopes for you."

"There will be more in the future, contact me as soon as possible."

"From now on, you are my Night Watch family, my...arrogant friend."

Looking at this message.

Fang Yuan couldn't calm down for a long time.

He even felt that the gold source crystal in his hand was a little bit less fragrant.

He blurted out a sentence after a long time.

"No~"

"Is this person sick?"

"Forget it, for the sake of the golden source crystal, bear with it."

"Let's upgrade the level of the northern defense line first."

Fang Yuan closed the panel of the trade market and opened the building module.

Rebirth began to upgrade the northern defense line.

And this time.

Fang Yuan directly upgraded the level of the northern defense line to level nine.

And just when it was upgraded to level nine.

The message that popped up after the upgrade was successful made Fang Yuan frown.

"Ding, the northern defense line has been upgraded to level nine, and the golden auxiliary building, the evil god ruins altar, is open."
