"The second-level northern defense line hasn't changed much compared to the first-level."

"In addition to the durability of the building, these have increased."

"In addition, the unit of output, the daily consumption has also increased."

However, these were nothing in Fang Yuan's opinion.

He is most concerned about the conditions for subsequent upgrades, whether there are any new increases.

Fang Yuan pulled the building panel down.

The conditions for two to three were found.

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

2. Earn the title of First Champion of Gondor (completed)

Second, defeat a Prairie Orange Legion (completed).

See the conditions for the upgrade.

Fang Yuan's eyes couldn't help but light up.

"Actually!"

"It's that simple."

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

"It's just that the first condition will change a little, increasing the consumption of golden source crystals, gold coins, and resources."

"However, the mere 20 million gold coins and resources are completely sprinkled with water for the current self, and they are not worth mentioning at all."

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

"Defeat the Prairie Orange Army, I don't know how many I have defeated."

At this time, Fang Yuan couldn't help but think.

"It seems that even if it is a golden building, the conditions for its upgrade will not be too difficult."

"Otherwise, you won't be able to rise at all."

"It's still negative equity."

"That's just right, hurry up and raise the northern defense line."

"It's better for me to mass-produce the magic crystal cannon as soon as possible, and go south to attack Gondor as soon as possible."

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

"Ding, the upgrade is successful, and you have obtained the third-level golden military fortress northern defense line."

Upgrading to the third level does not change much from the second level.

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

Check out the conditions for three liters four.

And when he saw it, Fang Yuan's eyes showed a look of surprise.

"It's done again!"

"This fourth condition is actually so simple."

[Upgrade Conditions]: 1. 30 million gold coins, resources, and 30 golden source crystals.

2. Earn the title of First Champion of Gondor (completed)

Three, defeat a Prairie Orange Legion (completed).

Fourth, kill a Prairie Orange hero (completed).

The fourth new condition is simply to kill an orange hero.

On the grassland, let alone orange, the golden sword master has been killed.

Naturally, this condition can't get stuck on itself.

At the same time, Fang Yuan thought again.

"If you extrapolate from this."

"Is it possible to complete all the conditions for subsequent upgrades?"

"The only condition for you to upgrade to the ninth-level northern fortress may be the resources and golden source crystals in the first condition."

"And gold and resources!"

"Although the loss is relatively large when transmitting."

"But there are still billions."

"It's only level nine, it's enough to spend."

"It's this Golden Source Crystal!"

"There are only 150 in total, and they have just been upgraded to three levels, 30 have been used, and there are 120 left."

"Push down, you can rise to level six at most, and the golden source crystals will all be consumed."

Fang Yuan also didn't expect that it was still the golden source crystal that stuck him in the future.

He shook his head helplessly.

"Forget it, let's use up all of this first and then think of other ways."

Fang Yuan selects the building and selects the upgrade.

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

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

And the golden source crystals needed for four liters and five are 40.

You can still move up the next level.

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

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

[Upgrade conditions]: 1. 40 million gold coins, resources, 40 golden source crystals.

Second, omitted

Three, omitted

Fourth, omitted

5. Occupation of more than two hundred hectares of land in the steppe (completed)

Fang Yuan touched his chin.

"Just 200 hectares of land."

"Huh."

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

"It's an easy one."

"Keep upgrading."

A pop-up message is accompanied by a liege's mark.

The Golden Northern Defense Fortress has been upgraded to level five.

And when it came to five liters and six.

That's 50 gold source crystals.

And the remaining golden source crystal in his hand now is just enough to rise to level six.

Since he could level up, Fang Yuan naturally wouldn't hide it.

Pulled the panel to the sixth conditional view.

At this glance, a smile appeared on his face again.

"Sure enough!"

"It's still done!"

[Upgrade Conditions]: 1. 50 million gold coins, resources, and 50 golden source crystals.

Second, omitted

Three, omitted

Fourth, omitted

Five, omitted

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

Let's be honest.

It's really hard to get the sixth condition done now.

First of all, you have to pull the orcs over and fight, and you have to be able to win against the orcs.

Swap for another lord.

For this condition.

I'm afraid that the entire coalition can be mobilized.

After that, thousands of lords from other countries had to be hired.

Then the preparation has to be prepared for several months before daring to start.

Fortunately, I don't need to.

Before this, he had already made a move against the orcs on the steppe in advance.

Annihilated their main force southward.

This condition was met ahead of schedule.

At the same time, Fang Yuan was also happy.

This promotion condition is to recognize one's previous record.

Then Fang Yuan directly selected and selected to upgrade again.

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

And to the sixth level.

Fang Yuan also knew that if he was promoted to the seventh level, he should be out of action for the time being.

It's mainly stuck on the golden source crystal.

Now I really don't have one in my hand.

However, Fang Yuan was still more curious.

What is the seventh condition of this six-liter seven.

He pulled the fortress panel down.

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

Second, omitted

Three, omitted

Fourth, omitted

Five, omitted

Sixth, omitted

7. Defeat a Golden Army on the Prairie (completed)

When you see the seventh condition.

Fang Yuan breathed a sigh of relief in his heart, and then said in a rather relaxed tone.

"It seems that the next thing is to get together the golden source crystals."

"I will be able to raise the level of the Northern Defense Fortress to level nine."

"I really didn't expect that the upgrade of the Northern Defense Line is even easier than the level of heroes."

"My previous order was really careless."

"The real order is to ascend to the northern fortress first, and then build a branch city."

"Finally, with the help of the war in the south, upgrade the hero level of your subordinates."

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

"You might be able to reach the full hero level."

"So now the northern defense line is full."

"The next step is to build a branch city."

"It's just the construction of the Golden Branch!"

"It's a lot of resources."

"Now I don't have enough resources in my hands."

"It's better to sell some loot and replenish some resources."

Fang Yuan's thoughts moved slightly, and he was about to teleport to the warehouse.

But this time.

A message pops up in the Lord's Sign.

"Ding, the trade market is stationed in the caravan, and the other party asks for a trade."

Fang Yuan's face was overjoyed when he heard the news.

"I didn't expect to have a target customer so soon."

"That's right, first change the golden source crystal in your hand, and raise the northern fortress to the ninth level in one go!"

Fang Yuan immediately opened the panel of the trade market.

Check out the names of the caravans that came to trade with them this time.

"Grandpai. What a caravan. ”

See the name of the caravan.

Fang Yuan's face twitched slightly.

"The name!"

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

"A lord who can take the name of such a caravan."

"It's not 250, it's really powerful."

"But I'm more inclined to the former."

"Of course, it's possible to have both."

"Let's test it first, if it's a pure 250."

"Directly blocked."

Just when Fang Yuan was thinking in his heart.

Ye Ao's message popped up.

"Make an offer!"

"I'll do it all."

"Don't question my strength."

"I have everything you want!"

See this message.

Fang Yuan didn't bother to think about it, and left a message directly.

"300 golden source crystals, no matter what the attributes."

This price was very high in Fang Yuan's opinion.

Generally, normal people would not agree to this kind of price.

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

Just wait for the other party to make a counteroffer.

Fang Yuan's reserve price is 210 Golden Source Crystals.

These source crystals just happened to raise the Northern Defense Line fortress to level nine by themselves.

If the other party thinks that 210 is expensive, it is a big deal for him to make up some other items.

But Fang Yuan calculated so much.

But I didn't calculate that the other party would agree to the deal.

"Deal!"

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

And then the news popped up in the trade market.

"Ding, the transaction is successful, you have obtained the Golden Source Crystal*300."

And along with this prompt, there is a new message.

"You're good."

"I, the Night's Watch family, are optimistic about you."

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

"From now on, you are my Night's Watch family, lord. Proud of my friend. ”

Look at the news.

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

I even felt that the golden source crystal in my hand was a little unfragrant.

He uttered a sentence for a long time.

"It's not~"

"This man is sick!"

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

"Let's raise the level of the Northern Defense Line first."

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

Rebirth begins to ascend the northern defenses.

And this time.

Fang Yuan directly raised the level of the Northern Defense Line to level ninth.

And just when you get to the ninth level.

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, the golden annex building, and the altar of the evil god relics have been opened."
