Zhang Nu opened up the reward treasure chest.

[You've opened the Gorgeous Mithminite Treasure Chest. You've gained "Gold" x 1,800,000, "Level 4 Building Upgrade Scroll" x1, "Blueprint: Tower of Evil Eye" x1, "Blueprint: Beholder's Lair" x1, "Dark Gem" x300, "Undeath Gem" x500!]

The Sealed Land was dangerous and treacherous.

However, in terms of scale, it was not very large.

After Zhang Nu and the young city lord took out the group of mannequins, they did not encounter any other monsters and ran straight into the encounter with the Eye of the Evil God.

Usually, in this case.

The gold reward would be relatively lesser compared to other areas with the same level and rank.

But the other types of rewards were still quite bountiful.

[Blueprint: Tower of Evil Eye] Level 4 blueprint. Costs gold x800,000, undeath gem x300, dark gem x200, stone x10,000. You may summon a Tower of Evil Eye within your territory.

[Blueprint: Beholder's Lair] Level 4 blueprint. Costs gold x1,000,000, dark gem x500, stone x20,000. You may summon a Beholder's Lair within your territory.

There were no Level 5 blueprints included in the rewards.

It was probably due to the extreme rarity of Level 5 blueprints.

Even in Level 5 areas, the drop rate of these blueprints was low.

Nevertheless, these two Level 4 blueprints acquired were not bad either.

The former was similar to the Tower of Grudges, Tower of Detection, Tower of Barrier, etc., which were defensive and precautionary structures.

However.

The Tower of Evil Eye was a Level 4 building.

Its functionality, effectiveness and power would be incomparable.

The latter blueprint of Beholder's Lair was obviously a barrack type structure and the value of a Level 4 barrack type building was extremely high.

The treasure chest this time.

Though it did not drop any Level 5 blueprints.

But it did give a Level 4 Building Upgrade Scroll.

This item could upgrade any Level 4 building into a Level 5, which could be considered to have indirectly obtained a Level 5 structure. This was more than enough to please Zhang Nu.

"The Evil God has been taken out!"

Nancilia was very thrilled and ecstatic.

The seal had bound the Giantree tribe for eons and had wrought disasters upon them numerous times. Was it finally completely resolved this time?

"Wait!"

"Something's wrong!"

Only now did Zhang Nu notice that after the Eye of the Evil God was blown to bits, its particles and fragments were still levitating in mid-air, and took the form of a mist-like mass.

When the cloud of mists gradually coalesced.

It reassembled into an eyeball once more.

Nancilia was utterly horrified, "The Eye! It resurrected!"

Zhang Nu shook his head, "No. It no longer possesses any power. This thing can't pose any threat to us anymore."

As he spoke, he grabbed onto the eyeball.

The moment Zhang Nu came in contact with the eyeball, the familiar bizarre and chaotic energy could be felt once again.

[You're under the effect of a negative energy. HP -5!]

[You're under the effect of a negative energy. HP -4!]

[You're under the effect of a negative energy. HP -5!]

[......]

The Eye of the Evil God no longer had any power, but its aura remained. It was still a very hazardous item for ordinary folks.

[You've obtained the "Evil God Fragment" x1. Would you like to assimilate it?]

[Note: The Evil God Fragment is extremely powerful. After absorbing the fragment, you will gain the power of the Evil God. However, your talents, bloodline and physique will be permanently affected. Please make the choice after utmost consideration.]

Zhang Nu received the information prompt.

Evil God Fragment? This thing could actually be absorbed!

Zhang Nu carefully observed the giant eyeball in his hand and examined it with his cheat ability for a more detailed description.

[Evil God's Eye] Orange grade special item.

......

Description: This is a fragment of the Evil God that has become temporarily dormant. You may take the opportunity to absorb it and thus ripping the talents and strength of an Evil God for yourself. However, you will inevitably succumb to the powers of the Evil God and eventually transform and trigger mutations. Only a bloodline with divinity can counteract this side effect.

Zhang Nu now understood.

Evil Gods were nigh impossible to be truly and completely vanquished.

It was only temporarily inactive.

This thing was currently an item and a material, but if left alone, it would come back to life within three months.

For Demon Kings and Heroes.

The Evil God fragment could be absorbed directly.

The function of this item was similar to skill stone but much more advanced.

Skill stones could only grant users a single skill. Whereas the Evil God fragment had the potential to give its user a whole set of skills.

Now, Zhang Nu only had to absorb this fragment.

And he would be able to obtain the skills of the Eight-Eyed Evil God and even gain a portion of its talents.

However.

Of course there was a price to pay for something so great.

There was the side effect of mutation and aberrations.

It would still be somewhat fine if the one kept absorbing the fragments from the same Evil God. As long as all the fragments were collected, the probability was the user would eventually become the Evil God itself.

But if fragments from different Evil Gods were assimilated and their power collided within the user's body, then the side effects and mutations would be completely uncontrollable. Who knew what kind of abomination or monstrosity one would turn into?

All in all.

This eyeball was of great value.

It was the biggest haul of this expedition.

But Zhang Nu did not intend to assimilate it now, as the description had shown, the side effects were not insurmountable.

Within Zhang Nu's Level 4 talents, there was one named "Dragon God Bloodline". As long as the talent was activated, he could access the potentials of the Dragon God.

First, acquire this divine bloodline.

Then, absorb the Evil God fragment.

Not only could Zhang Nu attain the power of the Evil God this way, he would be able to avoid its influence.

With the divine bloodline, even if Zhang Nu absorbed fragments from multiple Evil Gods in the future, he would not turn into a freakish abomination or monster while preserving his original talents, which could be said to be the best of both worlds.

"The Evil God is inactive now."

"It will no longer constitute a threat to the Giantree Forest."

Nancilia let out a long sigh of relief. She immediately relayed the good news to the elven elders, and the elves all cheered and bursted into tears.

"Thank you, Your Majesty!"

"Thank you for taking back the homeland of our tribe!"

"The elves of the Giantree tribe can finally return to their homeland and live in peace!"

Upon learning that the threat within the Giantree Forest was thoroughly settled, the elves were ecstatic and overwhelmed. Their loyalty to the great Demon King once again surged immeasurably.

From now on.

Not only could the elves live in Giantree City.

They could return to the Giantree Forest to restore and rebuild their homeland.

In the future, once Nancilia broke through to become an Elven King and the elven tribes from all over the world came to unite under her, the Giantree Forest could accommodate at least two or three hundred thousands of elves, which was also a positive in Zhang Nu's eyes.

After resolving the issue.

He returned to the Darkness City.

Zhang Nu then began the preparations for constructing the new buildings.

The "Tower of Evil Eye" and "Beholder's Lair" were both very pricey to build, but they were not a liability to Zhang Nu, as the yieldings from the expedition were more than enough to cover the relevant costs.

[Tower of Evil Eye successfully constructed!]

The Tower of Evil Eye was built within the Demon King's castle.

[Tower of Evil Eye] Level 4 building. 

Able to instantly reconnoiter all areas within a 500 km radius and detect all kinds of stealth units. Capable of inflicting violent psychic attack upon any target in a 50 km radius.

Judging from the description.

The Tower of Evil Eye was a defensive building integrated with both reconnaissance and offensive abilities.

It could both reconnoiter and attack, and its recon range was up to 500 km, which was several dozen times that of a Tower of Detection!

Its detection for stealthed and camouflaged units were also unmatched by the Level 1 Tower of Detection.

In addition, the Tower of Evil Eye was also capable of carrying out super long range attacks.

It could perform psychic attacks on any targets within its 50 km radius.

The Tower of Evil Eye itself was not all tall or eye-catching. By placing it next to the Demon King Altar would be both concealing and safe. No enemies would be able to get to it easily.

With it.

The territory's and the altar's security were undoubtedly improved significantly.

[Beholder's Lair construction successful!]

[You've unlocked the ability to summon beholder units!]

[You've gained a new summonable population: Beholder +50,000, Greater Beholder +10,000, Super Beholder +3,000, Abyssal Beholder +1,000, Beholder Lord +50, Greater Beholder Lord +10, Hellish Beholder Overlord +1!]

This was a Level 4 barracks-type building.

The strongest unit summonable was actually a Level 4 overlord unit.

The beholder race was a species of daemon that was relatively common in the underground world as well as the abyssal realm.

The strength and weakness of the beholders were very extreme.

Their disadvantages were: low intelligence, slow movement, incredibly fragile, and weak defense. They were basically doomed if an enemy got close to them, even if the enemy was lower level than themselves.

The advantages were: exceedingly long range perception, high attack power, and exceptionally long attack range. When encountering an opponent of the same level and rank, the beholder unit could usually detect the other party in advance, and instantly kill them.

Zhang Nu took a glance at the price list.

[Beholder] Level 1 elite unit. Costs 90 gold.

[Greater Beholder] Level 2 elite unit. Costs 900 gold.

[Super Beholder] Level 3 elite unit. Costs 5,000 gold.

[Abyssal Beholder] Level 4 elite unit. Costs 20,000 gold.

[Beholder Lord] Level 3 lord unit. Costs 40,000 gold.

[Greater Beholder Lord] Level 4 lord unit. Costs 200,000 gold.

[Hellish Beholder Overlord] Level 4 overlord unit. Costs 1,000,000 gold + 500 flame gems.

Overall.

The beholder units were not expensive.

In general, units summoned from barracks-type buildings were far less cost effective than the units of their own race.

For example, the orcish and elven Level 1 elite units cost 300 gold, while the price of a draconian soldier was only 100 gold.

In terms of overall combat strength.

The draconian soldier was superior.

The beholder, while being a Level 1 elite unit, cost only 90 gold, which was very affordable.

And the main reason for being so affordable was.

The beholders were not the same as the orcs and elves.

Not only did they embody some extremely obvious weaknesses, their intelligence was little to none and were incapable of performing any complex tasks, which was somewhat similar to the cheap undead units.

But for Zhang Nu.

The beholders were of great use.

These magical creatures possessed incredibly long attack range and high attack power, which could be used as a long-range attack force.

If the Darkness Valley, Giantree City and Berserk Beast City were equipped with a large number of beholders, they would suffice to greatly enhance the city defenses.

Every single beholder unit.

Was equivalent to a powerful sniper unit.

It would definitely become the enemies' nightmare!

It could both scout and attack against ground and aerial targets. It was a very practical unit species. Furthermore, when the beholders were out of combat, their daily consumption was very low as well!

For Zhang Nu.

The unlocking of beholder species was the perfect addition to his army.
