Global Demon King: Choose the Abyss Dragon at the start

【Undead Building Upgrade Scroll], consume this item, undead gems (first level) × 8, gold coins × 2000, only valid for first level undead type buildings, can improve the level of undead type buildings

【Blueprint: Wraith Tower], which consumes Undead Gem (First Level) × 1, Stone × 100, Wood × 50, and Gold Coin × 500 to build the Wraith Tower. The number of times this blueprint can be used is: 5.

It is indeed a lord-level area.

The greater the difficulty, the greater the harvest.

Both of these items are good things.

The former can be used to upgrade the undead facilities in the territory, and the latter seems to be a blueprint for a tower defense building. Unlike ordinary architectural blueprints, this blueprint can be reused five times.

Except for these two items.

The harvest of gold coins was as high as 5,000.

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

Zhang Mu did not leave immediately. He called his men in and asked the dragon men to dig out the area where the resentful spirit tree was and dug a large pit more than ten meters deep.

"Owner!"

"Something was discovered!"

Under the roots of the Millennium Wraith Tree, there are densely packed gems, as many as fifteen, all of which are undead gems.

Zhang Mu showed an unexpected expression.

The reason why he can predict the future is, of course, the prompt from Goldfinger.

The Wraith Tree can absorb the energy of the undead. The huge energy accumulates over time and can be condensed into undead gems. When necessary, these gems can be used by the Wraith Tree as a power bank.

But it is a pity. It met Zhang Mu.

The savings are useless. Hanged up.

This resentful spirit tree is very old. It has condensed fifteen undead gems. The number is much more than expected. It is another unexpected surprise.

These undead gems are very useful.

After spending a day cleaning the mine.

The dragonmen eliminated all the zombies, dragged the corpses out and burned them, and began to rebuild the mine tunnel. Mining here will soon be possible.

Mining requires a lot of labor.

Goblins, skeleton soldiers, small arms and legs, and no strength , there is no way to do it, and a group of dragon laborers have to be recruited.

Zhang Mu returned to the territory

【Tip: Do you want to spend 1 upgrade scroll, 8 undead gems, and 1000 gold coins to upgrade the Tomb of Bones?】

"yes!"

Zhang Mu made a choice

【Tip: Your"Comb of Bones" is upgraded to"Comb of Skeletons""！】

The upgrade was successful.

Zhang Mu couldn't wait to see the changes.

First of all, the appearance has changed a lot.

The Tomb of Bones is like a messy mass grave, and the Tomb of Skulls is a huge tomb of bones, at least it has been upgraded a few levels.

Of course.

Zhang Mu is not so superficial.

He pays more attention to changes in functionality.

Inside the Tomb of Skulls.

Undead recovery speed increased by 50%.

The maximum number of skeleton soldiers has been increased tenfold.

In addition, two new units have been added.

Skeleton Mage, a first-level elite, the recruitment price is 150 gold coins each, and the recruitment limit is 50.

Skull leader, second level ordinary. The recruitment price is 100 gold coins each, and the recruitment limit is 100 people. very good.

It's not a waste to upgrade to this level.

The functional gap between the Tomb of Skulls and the Tomb of Dry Bones is too great.

After Zhang Mu owns the Skeleton Tomb, he will be able to recruit 1,000 skeleton soldiers + 100 skeleton leaders + 50 skeleton mages, which is enough to greatly increase the strength of the territory.

As for why the first-level skeleton mage is more expensive than the second-level skeleton leader.

Very normal.

Skeleton Mage is an elite monster.

The skull leader is just a second-level ordinary monster.

Not to mention that magic units are more valuable, but in terms of combat effectiveness, the Skeleton Mage is slightly better than the Skeleton Leader.

The Skull Leader is not without its faults.

The second-level skeleton is several times larger than the first-level skeleton. Both its defense against attacks and its strength are greatly increased. It is very convenient for fighting or doing hard work.

It can be said.

There is the Tomb of Skulls.

The strength of the territory has undoubtedly increased significantly.

Zhang Mu was not satisfied. He wanted to further enhance the territory's defense, and at this time he would use the"Wraith Spirit Tower" blueprint.

The Wraith Tower is a defensive undead building.

Its ability is somewhat similar to the Wraith Tree. Once an enemy enters the sensing range, it will automatically summon a self-destructing Wraith to chase the enemy.

There are two suitable places to build.

They are: in the dark canyon, or near the Demon King's Castle.

The former has a narrow terrain and is the main passage of the valley. The Wraith Tower can play a great role in this environment. The latter is the base camp and the location of the core facility, the Demon King's Altar, which indeed needs special protection.

After some consideration.

Or put it in the canyon.

If all the enemies have reached the base camp.

The facilities in the territory will definitely suffer heavy losses.

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

Half a day later.

Dark Canyon.

Five towers of bones rise from the ground.

They are piled with terrifying skulls from top to bottom, and their appearance alone is scary enough. When a warrior enters the canyon and sees them, his anus will tighten.

Zhang Mu's deployment is completed.

Very pleased with this masterpiece.

At this time, a dragon man hurriedly came to report

"Report to my lord!"

"There are minotaurs out there!"

"They are trying to enter the territory!"

Zhang Mu feels like he is another warrior who wants to steal his home.

What a coincidence.

Aren't these guinea pigs?

Let's use them for experiments!
