Global Demon King: Choose the Abyss Dragon at the start

[Undead Building Upgrade Volume], consume this item, undead gem (first order) × 8, gold × 2000, only valid for first-order undead buildings, can increase the level of undead buildings.

[Blueprint: Wraith Tower], consume 1 undead gem (first order×), 1 stone ×, 50 wood ×, and × 500 gold coins, you can build a wraith tower, the number of times this drawing can be used: 5.

It's a lord-level area.

The greater the difficulty, the greater the reward.

Both of these items are good things.

The former can be used to upgrade undead facilities in the realm, while the latter appears to be a blueprint for a tower defense building, which can be reused five times, unlike normal architectural drawings.

In addition to these two items.

The gold coins are harvested as high as 5,000.

This amount of money is a huge amount of money at this stage, no matter how you look at it.

Zhang Mu didn't leave immediately, he called his men in and asked the dragonmen to dig the area where the resentful spirit tree was located, digging a large pit more than ten meters deep.

"Master!".

"Found out!".

At the base of the thousand-year-old spirit tree, there are dense gems, as many as fifteen, all of which are undead gems.

Zhang Mu showed an unsurprising expression.

The reason why he can predict the prophet is, of course, also from the hint of Goldfinger.

The Wraith Tree can absorb the energy of the undead, and the huge energy accumulates over time, which can be condensed into undead gems, which can be used as power banks by the Wraith Tree when necessary.

But it's a pity.

It met Zhang Mu.

The savings were useless and hung up.

This Wraith Tree was very old, condensing fifteen undead gems, the number of which greatly exceeded expectations, and it was an unexpected surprise.

These undead gems.

Just a lot of usefulness.

After spending a day cleaning the mine.

The Dragonmen took out all the zombies, dragged the corpses out and burned them, and began to renovate the mines, which would soon be ready for mining.

Mining requires a lot of labor.

Goblins, skeleton soldiers, small arms and legs, and no strength, no way to do it, and they have to recruit a group of dragonmen to do it.

Zhang Mu returned to the territory.

[Hint: Do you consume upgrade volume × 1, undead gem × 8, and gold × 1000 to upgrade the Dry Bone Grave?].

"Yes!".

Zhang Mu made a choice.

[Hint: Your "Grave of Dry Bones" has been upgraded to "Grave of Bones"!].

The upgrade was successful.

Zhang Mu can't wait to see the changes.

The first is that the shape has changed a lot.

The Tomb of Dry Bones is like a messy mass grave, and the Tomb of Bones is a huge tomb of bones, at least a few notches higher.

Of course.

Zhang Mu is not so superficial.

He is more concerned with changes in function.

Inside the Skeleton Grave.

Undead regeneration rate increased by 50%.

Skeleton limit increased tenfold.

In addition, two new units have been added.

Skeleton Mage, a first-order elite, has a recruitment price of 150 gold per one, and the maximum recruitment limit is 50.

Skeleton Boss, 2nd Order Normal. The recruitment price is 100 gold coins per recruitment, and the recruitment limit is 100.

Very good.

It's not in vain to move up this level.

The difference between the functions of the Skeleton Grave and the Dry Bone Grave is too great.

After Zhang Mu owns the Skeleton Tomb, he will be able to recruit 1000 skeleton soldiers + 100 skeleton bosses + 50 skeleton mages, which is enough to greatly increase the strength of the territory.

As for why a first-order skeleton mage is more expensive than a second-order skeleton leader.

It's normal.

Skeleton Mages are elite monsters.

The Skeleton Boss is just a second-order normal monster.

Let's not say that French units are more precious, but compared to combat effectiveness, skeleton mages are slightly better than skeleton leaders.

The Skull Boss is not for nothing.

Second-order skeletons are several times larger than first-order skeletons, and both defense and attack and strength have greatly increased, making it very convenient for both combat and coolies.

Arguably.

There is a grave of skulls.

The strength of the territory has undoubtedly increased significantly.

Zhang Mu was not satisfied, he wanted to further strengthen the defense of the territory, and at this time, he would use the "Resentful Spirit Tower" blueprint.

The Wraith Tower is a defensive undead structure.

Its ability is somewhat similar to that of the Wraith Tree, and once an enemy enters the sensing range, it will automatically summon a self-detonating Wraith to chase down the enemy.

There are two suitable places to build.

They are: in the Dark Canyon, or near the Demon King's Castle.

The former's narrow terrain is the main passage of the valley, and the Wraith Tower can play a great role in this environment. The latter is the base camp, where the core facility Demon King Altar is located, and it really needs extra protection.

Weigh it over.

Or put it in the canyon.

If the enemy has hit the base camp.

There will be a lot of damage to the facilities in the territory.

Therefore, it is better to try to keep the enemy out of the territory.

Half a day later.

Gloomy Canyon.

Five towers of bones rose from the ground.

They were piled up with terrifying skulls from top to bottom, and the mere appearance was scary enough, and the warriors who entered the canyon and saw it would feel Kikube tight.

Zhang Mu has completed the deployment.

I am very pleased with this masterpiece.

At this time, a dragon man hurriedly came to report.

"Tell my lord!"

"There's a minotaur out there!".

"They are trying to enter the territory!".

Zhang Mu felt that he was a warrior who wanted to steal his family again.

Coincidentally.

Isn't this a guinea pig?

Let's use them for experiments!
