For Huang Yu, the defensive performance of a rare-grade city wall can only be said to be quite satisfactory.

The reason for buying it is to use it as a spare city wall for the territory to advance to the fifth rank.

After all, the discount of Obsidian City Wall is very low. It would be a pity if you don't buy it this time.

If you encounter a more suitable city wall before and after the upgrade of the fire to the fifth level, you can also sell it and replace it with a better city wall.

After all, the obsidian city wall is a rare grade city wall, and it also has explosion-proof performance. Even for other human lords, the performance is very good.

Top lords such as Kashid, Chitian, and Kaguya should now be in the stage of upgrading the fire to Tier 4, and the obsidian city wall should not be weak to them.

Therefore, the 50KM obsidian city wall in Huang Yu's hands is a fixed asset that can be realized at any time.

If you need soul crystals urgently in the future, you can also sell them on the shelves of the Universal Store.

After all, the cost is only 150,000 soul crystals. As long as you don't mind, you can make a lot of money no matter how you sell it!

Moreover, with the removal of the alien forces around the territory, the Universal Territory must also consider expanding outwards, and it may be necessary to establish several important military towns at that time.

These obsidian city walls can also be used in these sub-territories, and it is difficult for general animal tides, alien armies, etc. to cause a destructive threat to them.

"The 50KM obsidian city wall is still a bit too much."

Huang Yu thought about it for a while, and divided the 10KM obsidian city wall, with a price of 50 soul crystals per meter, and set the 2KM obsidian city wall as one unit, and a total of five units were put on sale in the Universal Store.

He left behind a 40KM obsidian city wall for emergencies.

Rare grade city walls are cheaper by 10 soul crystals per meter, which is equivalent to a 13% discount on Chaos Mall. For every 2KM of obsidian city walls, you can save 20,000 soul crystals!

This price is already quite favorable.

Walls purchased in Chaos Mall can only be built within the territory.

Although the ten-kilometer city wall cannot surround the entire fourth-order territory, it can protect the buildings in the core area like the forbidden wall of the inner city of the universe.

Some lords who cannot raise the fire to Tier 4 in the short term, or who have insufficient soul crystals after raising Tier 4, should be more favored.

Sure enough, not long after it was put on the shelves, Huang Yu received a transaction notification after the obsidian city wall was sold.

[Lord Omenia paid 200,000 soul crystals to buy 4KM of rare obsidian city walls!

[Lord Zilan paid 200,000...4KM!

[Lord Starscar... 2km!

In less than half a minute, 500,000 soul crystals were credited.

Huang Yu still holds the 40KM city wall in his hand, but he has already made a net profit of 350,000 soul crystals!

Subsequently, Huang Yu picked out a few more discounted items to buy, and then began to resell other discounted items.

Just like yesterday, he put the awakening medium that appeared in the super-grade discounted products in the Universal Store.

By the time these are all sold out, there are already 4.75 million soul crystals in his hand!

Of course, earning so much is still related to Huang Yu's restraint in spending today.

For example, there is an epic special building in the Chaos Mall today, which is a spellcaster organization called the Clock Tower.

But because its original price is not as good as the crown of mystery, the price after 20% off requires Huang Yu to sell all the obsidian walls to make up enough.

And its functional properties are similar to the Crown of Mysteries, so Huang Yu gave up after a little hesitation.

The soul crystal in his hand is more for his long-awaited awakening medium, and buying a research-type spellcaster organization is not worth it.

For the same reason, there is a human warrior in the extraordinary grade, and Huang Yu did not buy it.

The current hero units in Huang Yu's territory have exceeded 300 people, and they are still increasing.

The future mid-to-high-end combat power in his hands is already enough to no longer be sufficient.

Flying to the observation deck at the top of the castle, Huang Yu briefly admired his own country for a while, then called up the information panels of the black-scaled leopard's nest and the stone horned beast's nest, and chose to upgrade them.

Gu[Please allocate the special building materials needed to upgrade the black-scaled leopard's nest to the fourth level!

"200 units of ambergris, 400 units of shadow stone, 200 units of imperial spirit stone, 200 units of blood sun stone!"

[Satisfy the upgrade... consumes 230,000 soul crystals... Please confirm whether to upgrade?

[Please allocate the special building materials needed to upgrade the black-scaled leopard's lair to the fourth level!

"200 units of ambergris, 200 units of soul-cultivating stones, 200 units of royal spirit stones, 200 units of blood sun stones, 200 units of dragon elephant stones!"

[Satisfy the upgrade... consumes 80,000 soul crystals... Please confirm whether to upgrade?

Huang Yu clicked to confirm one by one, and the 310,000 soul crystals and various materials disappeared at the same time.

And the fire separated two golden lights, covering the black-scaled leopard's lair and the stone horned beast's lair.

Tonight, two types of mount nests will be upgraded!

buzz~

At this moment, the communication crystal in Huang Yu's arms began to vibrate.

Taking out the communication crystal, Huang Yu found that it was Ryana who sent a video.

The aliens that the Amazon female warriors deal with today are ghost-faced bats with the ability to fly.

Therefore, Huang Yu specially asked Ryana to train a group of flying maglev fighters to act as air combat troops before the expedition.

This is the first air battle of the Universal Army, and it is of special significance.

So Huang Yu arranged for Ryan to send someone to record the battle information.

Soon after the battle, the video was sent to him.

In the southern bay of Universal City, there is a rock pile lined with boulders.

On these reefs, there are often some strange-shaped buildings, and in the most central position, there is an inverted triangle castle, which is fixed on the three thickest stone pillars.

And here is the ghost-faced bat man's territory.

The ghost-faced bat is a variant of the bat-man in the half-orc family. Because of the white lines on its face, it looks like a ghost, so it is called the ghost-faced bat.

The ghost-faced bat territory here, UU reading www. uukanshu.com is a third-order territory, and this reef forest is almost completely occupied by them.

During the day, they generally hid in the shadows between the boulders to rest, and only at night would they leave the territory to hunt wild monsters and collect resources.

Because they are born with the ability to fly, and the environmental structure of the territory is very complex, the threat to them is relatively limited every time the beast tide.

Thanks to this, their territory has developed quite well, and the number of territorial residents has almost exceeded 2,000.

But today, their peaceful and slumbering day was broken.

"Enemy attack!!"

A howl woke the ghost-faced bat lord from his sleep.

It grabbed the ceiling of the castle with its feet and slumped down.

The moment it heard the warning, its eyes had not yet opened, but its body was already wrapped in its wings and flew out of the castle.

Under the nasty sunlight, the ghost-faced bat lord opened his eyes to check his territory.

Immediately, it angrily discovered that at some point, more than 200 residents outside the territory, as well as dozens of sentry ghost-faced bat warriors, had fallen to the ground and died in a pool of blood.

In the territory, there is a group of humans swinging among the boulders, chasing and killing its subjects.
