Rist didn't know what Chen Gu wanted to do, but the big goblins and biochemical forest spirits that Chen Gu pointed out were all soldiers of relatively good quality that he himself was optimistic about.

Seeing that Chen Gu wanted these soldiers, Lister quickly called people out.

At this time, Chen Gu was already on the side of selecting the appropriate hero credentials and synthetic materials.

Soon Chen Gu picked out the right thing.

The hero credentials are from the eyes of the walking corpses, and the crafting material is the water from the hot springs in front of you.

"Come here."

Chen Gu pointed to a biochemical forest spirit and said.

As soon as this biochemical forest spirit heard this, he immediately stood up.

These Biochemical Forest Spirits and Great Elves have been synthesized at least once.

They all knew what Chen Gu had called them out for.

"Stand over there, this water is not for you to drink, you hold it in your hand, I'll see what else there is, this is a life potion, you can take it too, it doesn't seem to work, then change this?"

Just as Chen Gu was there to adjust the synthesis formula, a corpse vine came out of the ground.

He spat out an ice-blue stone, although the stone was cold-colored, but in his hand, he could clearly feel the temperature coming from inside, and at the same time, there was a strong smell of sulfur on the stone.

"Is that it?"

Seeing the ghoul vine spit things out, Chen Gu had a guess, "The hot spring was created because of this?" ”

The ghoul vine nodded, and made a motion.

Chen Gu immediately knew that there was a large mineral vein underground.

The original Shadow Moon Fortress was prepared for this ore.

"How many of these things are down there?"

An idea suddenly appeared in Chen Gu's heart.

To be able to build a city here, this vein below must be huge.

The ghoul vine writhed continuously, but there was no way to explain how big the veins below were.

Chen Gu looked at it for a moment and said directly: "Forget it, you lead the way in front, I'll go down and take a look." ”

Saying that, Chen Gu called the vine carriage, sat in the coachman's position, and went directly to the ground.

After entering the ground, Chen Gu and the others first passed through a layer of spring water, and then they saw a small vein about thirty meters underground.

This vein is about 300 meters long, and it is full of such stones.

According to Chen Gu's estimate, if all the stones here are mined, not to mention the rest, it will be enough to rebuild this Shadow Moon Fortress.

Originally, Chen Gu thought that such a vein was already quite remarkable.

After all, these things are not real stones, they must have other functions.

But Chen Gu never expected that the corpse eating vine would find more than that.

About forty meters further down, there was an even larger vein.

This vein is more than 3,000 meters long, more than 60 meters wide, and more than 30 meters high.

And this is only the discovery of human attachment now, not far away, there are still intermittent veins.

Chen Gu estimated that in the past, the total amount of ore veins here should be calculated in 10,000 tons.

Now it's not clear what this ore does.

Chen Gu thought for a moment and immediately returned to the ground.

At this time, the Great Goblin and Biochemical Forest Spirit who were called out by Chen Gu were still waiting there.

"Put the water down from your hands and take this stone."

As the stone was put up, Chen Gu quickly got a new synthesis formula.

[Biochemical Forest Spirit] + [Light Absorber] = [??? (23.7% success rate)】

Chen Gu was not surprised that the success rate of synthesis was so low, he mainly wanted to take a look at the situation of these stones.

This type of stone, called absorberite, absorbs the temperature and power of sunlight.

It can be used to craft weapons and equipment, and it can also be used to craft magic scrolls or something.

It's a good material.

It's just that this thing doesn't fit into the biochemical forest spirits.

If the biochemical forest spirit wants to be strengthened, it is most suitable to strengthen materials such as trees, this kind of light absorbing stone, even if it has the effect of absorbing the power of sunlight, it is also a stone, which is not compatible with the attributes of the biochemical forest element.

Therefore, Chen Gu simply took the light-absorbing stone back, and put the hero certificate that he was going to give to the biochemical forest spirit on the side of the light-absorbing stone.

Chen Gu planned to use the light-absorbing stone to clean up the undead aura on the hero credentials.

This time, the situation is exactly what Chen Gu thinks.

When the light-absorbing stone is placed together with the hero credential, a moonlight-like light lights up.

At first, Chen Gu thought it was a light falling from the sky.

But soon Chen Gu understood that this was the sunlight that the absorber had absorbed before.

It's just that it was stimulated by the breath of the undead, so it was released directly.

Under the influence of the moonlight, the hero's credentials, which looked like the eyes of the walking corpse, also slowly changed.

The hero certificate still looks like an eye in the end, but instead of an eyeball of a walking corpse, it is a knot that looks like an eye.

At this time, the attribute of the hero voucher is also transformed from the attribute of the undead.

Chen Gu looked at the situation in front of him, and a smile appeared in his eyes.

When he started, he was always worried about the conversion of hero credentials.

As he thought, there was no way he could turn all of his men into Light Magma or the same kind of troops.

Now that he had the means to cleanse the undead aura on the hero credentials, Chen Gu was naturally much more relaxed.

"You try it with this."

Throwing the Ying voucher to the biochemical forest spirit, Chen Gu retreated to the side to observe.

The biochemical forest spirit also understood that this was another opportunity, although it was not as powerful as the one synthesized in Chen Gu's hands, but it was also a way out.

After all, not every soldier can get a hero credential and turn into a hero.

The biochemical forest spirit took this hero certificate, thought about it, and directly pressed this knot-like thing to his abdomen.

Then the vines around the biochemical forest spirit quickly pierced in, and at the same time, turquoise leaves grew on the vines, quickly forming a set of armor-like things.

This change lasted about seven or eight minutes.

After the change was over, an elf who was obviously much bigger appeared in front of Chen Gu.
