Kebas took out the things one by one, and Chen Gu also looked at them carefully.

[Heart of the City - Rotten Evil Temple: You can build an undead city in a designated location, mainly to produce skeleton soldiers, and the city level is capped at level 3. 】

[Heart of the City - White Bone Beast Fence: An undead city can be built in a designated location, mainly to produce white bone monsters, and the city level is capped at level 5. 】

The attributes of the two city hearts were quickly discovered.

However, the energy source that is valued by Kebas has not been born.

Chen Gu only knew that this was a synthetic material, and he could also feel the powerful energy inside.

However, this energy is all the energy of the undead, and at a glance, you can tell that all the souls are burning inside, and if this thing is placed in the hands of other lords, it will definitely be usable.

But here in Chen Gu, it's different.

His lordship world had problems at the beginning.

All undead are under the control of Black Castle.

Even if Chen Gu got the undead troops, there was no way to control them.

Whether it was the heart of the city or this undead energy, Chen Gu had to adjust it before using it.

Chen Gu thought for a moment, he took out the heart of the city in the White Bone Beast Fence, and then Chen Gu pointed to the ground, and ten holy light magma and thirty fire elements were released in this way.

Then Chen Gu rummaged through the carriage and found a few pieces of the Fire Elemental Heart.

It's just a pity, the holy lake water brought by Chen Gu before has been used up, or the water of the holy lake is a high-grade holy water, and it is best to use it to wash the heart of the city.

【Lair Synthesis Begins......】

[Please provide a piece of the corresponding attribute building stone or the heart of the city (0/1), please provide a formula that has been synthesized successfully (0/1), please provide ten copies of synthetic materials (0/10)]

Chen Gu quickly dealt with the heart of the city in his hands.

He arranged the Holy Light Holy Pulp and the Fire Elemental into it, and put in a few Fire Elemental Cores.

Then the heart of the city, which looked like a beast's skull, quickly lit up.

Then a flame burned around the heart of the city.

Chen Gu quickly changed some of the information in the heart of the city.

Changing and changing, Chen Gu felt that he had miscalculated, and he should use that level 3 city heart to change the synthesis.

The development direction of this heart of the city is dominated by the Bone Behemoth, and all the technology in it revolves around the Bone Behemoth.

This time, Chen Gu's synthesis can be regarded as a major change.

But he had already started synthesizing, and even if Chen Gu had any more ideas, it would be too late.

At this time, he could only bite the bullet and continue.

Fortunately, the success rate of nest synthesis is not considered, as long as everything that needs to be changed in it is changed, then there will be no problem.

It took about four hours for Chen Gu to complete the change to the heart of the city.

The heart of the new city was like a flame, held in Chen Gu's hands.

[The nest is synthesized and you get the Level 5 City Heart - Flame Behemoth]

Description: This is a building stone transformed from the heart of the undead city, and although everything has been washed away, some things are still left, such as the base for training ordinary beasts and synthetic behemoths.

Glancing at the attributes of the heart of the city, Peter and the others glanced at each other.

Finally, Peter had to say, "My lord, this is a great way to do this. ”

"Average, it's nothing."

Chen Gu smiled, and then said to Kebas: "Kebas, there is a task given to you now, you know the previous Holy Helmet Valley, right?" ”

"Oh, that place, I know, but I haven't been there."

"One of my subordinates over there in the Holy Helmet Valley, the Holy Rock has occupied it, he controls nearly 200,000 fire elements, this city heart is prepared for him by me, you help me send this city heart over.

I'll head south first, and you'll come back to me as soon as you send the heart of the city. ”

"Don't worry, my lord, I will definitely send this heart of the city."

Only then did Brufeld raise his head and say with some sighs: "It's a pity that this city heart is really a pity, if it can be combined into the city heart of Hydra, the effect will be much better." ”

Chen Gu turned his head to look at Brufeld and found that he was looking at the heart of the city that Kebas was holding in his hand with a look of pity.

Chen Gu was stunned for a moment before saying: "Yes, next time I encounter such a situation, I must first see the direction of each city heart, this time when synthesizing, I am almost tired."

If you use that level 3 one, it won't be like this. ”

Listening to Chen Gu's words, Peter and the three of them sighed at the same time.

It's a shame this time.

But no matter how sorry it is, it's useless.

The level of hydra is relatively high, whether it is Chen Gu or Brufeld, you can't use a level 3 city to raise a group of hydra.

In the future, the hydra can only hang in the city of the black nest.

There is no way to go any further and come out of a city on its own.

And Peter wouldn't be willing to take the city of the Black Nest to synthesize.

So the synthesis is almost over.

At this time, Chen Gu was thinking about another thing.

"Brunfield, did you feel anything about that huge guy when you fought him before?"

Big guy, Brunfield reacted as soon as he heard it, Chen Gu was talking about the white bone giant beast that had moved and urbanized.

Speaking of which, the white bone giant beast was really a bit wasteful, in order to turn this white bone giant beast into a mobile city, it actually directly applied two pieces of city hearts.

Normally, for those who have this technology, it is enough to use a piece of the heart of the city.

However, he used two pieces, although there was a need for the technology and technology in the heart of the city.

But deeper it is a different story.

The undead leader has a background.
