After Kebas went out again, Chen Gu also turned his attention to the heart of the city and the building stones.

Kebas's idea just now told Chen Gu another idea.

If there was no Dao encounter to wash away the breath of the undead before, it was because the material properties were not strong.

Now that there is a material synthesis cabinet, the material properties are not strong, so it is better to strengthen it.

In this way, this level 9 city heart has a way to clean up.

Chen Gu quickly found out the various materials he had obtained before, and quickly combined them to upgrade.

Soon Chen Gu discovered that among the materials he was carrying, there was one that could just handle this level 9 city heart.

It was some of the dirt that Chen Gu had dug up on the Holy Lake Island before.

This dirt was originally used to craft Holy Light Magma.

However, he dug a little more, and when Chen Gu learned the magic of summoning holy light magma, he didn't use the dirt anymore.

But now it's different, after Chen Gu put the soil into the material synthesis cabinet, he immediately turned on the synthesis function.

The last thing that came out of the crafting cabinet was a much harder piece of dirt.

【Holy Earth (Green): Contains a powerful clay that can be used to make jewelry and can also be used as a crafting material. 】

Looking at the attributes of the holy land in front of him, Chen Gu shook his head.

He felt that this was not enough, but the green quality holy land could not affect the heart of the city at level 9.

Chen Gu put the synthesized holy soil into the material synthesis cabinet again, and after this synthesis, Chen Gu only took out a piece of black soil the size of a brick from it.

[Holy Earth (Blue): Sacred Earth compressed to the extreme, which can be used to make blue quality jewelry or used as a synthetic material. 】

Looking at this attribute, Chen Gu had the heart to suppress it again.

But the soil he brought could only be combined into such a piece of holy soil, and no matter how much it was, there would be no more.

Chen Gu had no choice but to find another way, he turned out all kinds of things he had found on the Holy Lake Island before, the branches of the World Tree, those aquatic plants, barnacles, and mussels.

As long as everything that can be taken out, Chen Gu took it out and used it as a material.

After a few rounds of processing, Chen Gu had several more blue quality things in his hands.

Sacred soil the size of a square brick, a branch the thickness of an arm, a barnacle the size of a fist, a mussel the size of a palm, and a three-meter-long aquatic weed.

These things all have strong Holy Light properties.

With these five things, Chen Gu was ready to wash the heart of the city first.

First wash the undead attribute on it, and then think about how to change 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 did not have a completed formula for success, nor did he have enough synthetics.

The five things he had just taken out were all now counted as Holy Light attribute materials.

It can be counted in ten parts of the synthetic material.

However, this calculation can only be counted as five.

When Chen Gu was about to synthesize, he got a hint.

If Chen Gu forcibly synthesizes, then the probability of failure will be quite high.

At that time, all the attributes of the heart of the city will be erased.

But that's what Chen Gu wants.

He just wants to change the undead attribute of the heart of this city.

He didn't care if the level dropped a little.

After all, Chen Gu of the Undead City had no way to control it.

With Chen Gu's order, the things placed on the edge of the heart of the city quickly turned into powder, and then a large amount of white light shrouded the heart of the city.

The humanoid statues that guarded the heart of the city twisted in the white light.

They want to resist this white light, but the white light is quite useful.

As soon as they moved, the white light would scatter the statues.

After a while, Chen Gu saw that the shell of the Heart of the City had been opened, revealing the dark green Heart of the City underneath.

The elven breath that Chen Gu wore on his hand lit up at this time, and the color of the dark green heart of the city directly changed from dark green to tender green.

Chen Gu also reacted at this time, the previous natural demon mark was not the heart of the city brought by the undead army itself.

Rather, it was the heart of the city that was snatched from the elves, and then transformed through the transformation of the undead power.

The way they transform is to inject the breath of the dead into the heart of the city.

Chen Gu happened to find an opportunity this time, and the power of the holy light and the aura of the undead were neutralized, but the original heart of the city was turned over.

Most importantly, this heart of the city should be one of the heart of several core cities of the elves.

The Elven Breath Ring on Chen Gu's hand can just affect the heart of this city.

Under the influence of the Breath of the Elves, the heart of the city swept away its previous decadence and flashed a bright green light again.

At this time, Chen Gu also got the corresponding information.

【You got the heart of the city - forest garden】

[Heart of the City - Forest Garden: You can build a nature city in a designated location, mainly elves and other nature-friendly troops, and the city level is capped at level 11. 】

"Level 11?"

Chen Gu looked at the information in front of him and was taken aback on the spot.

He never imagined that the heart of this city would be level 11.

You must know that in the world of lords, the difference between level 11 and level 12 is actually not much, the only difference is that the city of level 12 is called the capital, and you can upgrade the council hall to the capital level.

A level 11 city can only be called the main city.

But the size of the city, the area of influence is actually about the same.

The forest garden in front of him turned out to be level 11, which couldn't help but surprise Chen Gu.

Then he seemed to have discovered something.

"Wait, Forest Garden?"

Chen Gu flipped out the elven map and quickly searched for it on the map.

Soon, he found the level 11 main city belonging to the elves in the northern part of the elven kingdom.

The name of the city is marked on the map, the Forest Garden.

At the same time, the map also shows the situation of the city.

The Elven Holy City is the main residence of the Elven Race, and the Forest Garden is the main city of the Elven vassal races.

In this city, there are elves and dwarves, there are all kinds of natural creatures such as goblins, forest fairies, forest elves, jungle elves, as well as natural animals and plants such as centaurs, unicorns, pegasus, owls, dryads, and treants.

It can be said that the forest garden is the most important source of auxiliaries in the elven kingdom.

Looking at the heart of the city in front of him, Chen Gu couldn't help but have an idea in his heart.

Could it be that after the undead laid down the forest garden, they directly demolished the heart of the city?
