Spellcasting is a permanent addition and my skills are all forbidden spells.

Listening to the system prompts, Lu Cheng's heart raced, and he instantly activated the flash and moved more than ten meters away.

At the same time, he quickly raised his hand to summon an energy barrier.

"Bang, bang!"

The next second, several black spheres bombarded his original position, exploded, and turned into dark attribute airflow to escape.

Avoiding the blow, Lu Cheng followed the reputation and walked away.

Behind him, he saw humanoid monsters with horns on their heads showing their fangs and roaring as they approached him.

These monsters look very similar to the demon servants in the ice cave. They have long tails and are surrounded by dark air currents.

I don't know if it was an illusion, but with the appearance of these monsters, the gray-black mist covering the top of the mountain became much thicker.

"This is... an elemental monster?"

Lu Cheng looked up and recognized the type of monster.

This kind of monster is quite special. It can combine source stones with various attributes and master spells with corresponding attributes.

The special thing is that after the elemental monsters are killed, the source stones they fused can be stripped out!

Looking at the previous spells, the source stones fused by these monsters are obviously dark attributes.

While his mind was spinning, he raised his hand and threw out the True Sight.

Under the true sight, the attributes of monsters are revealed.

…

【Elemental Monster】

[Level: Level 50]

[HP: 100,000/100,000]

[Status: Fusion of dark attribute source stone crystals x10]

…

Lu Cheng looked happy after seeing the monster's attributes clearly.

After searching for so long, the dark attribute stone is finally found!

As long as these elemental monsters are killed, the broken crystals will explode.

However... a thousand Origin Stone fragments can make up a whole Origin Stone.

There are just a few monsters, and the Origin Stone fragments contained in their bodies are not enough.

Lu Cheng looked around quickly.

It can cause fluctuations in the dark attribute airflow, covering the nearby area. There cannot be only three or two monsters around.

Sure enough, around the top of the mountain, the gray-black fog became thicker.

In the black mist, there was a low roar, followed by the sound of chaotic footsteps.

It was more monsters coming one after another, surrounding him from all directions!

"Well done!"

Lu Cheng's eyes lit up.

These monsters are all fused with dark attribute stones. The more they come, the more he gains!

"Roar……"

Several elemental monsters were running fast on their hands and feet, and they were close in a blink of an eye. Dark energy surged between their sharp claws, and they were trying to catch him!

"Cang! Cang!"

-

10524!

-

9191!

Manipulating the energy barrier to block the attack, Lu Cheng waved his staff, and the surrounding cold air condensed into an ice spear! -

110342!

-

105879!

-

109903…

The ice spear swept across and directly cut off these elemental monsters!

[Ding, you killed 4 elemental monsters (level 50), gained +130,000 experience points, and gained +04 source energy limit! 】

"thump……"

The body of the elemental monster fell to the ground, its vitality cut off, and fragments of Origin Stone crystals precipitated from its body.

At the same time, the beasts roared together, and a large number of elemental monsters jumped out of the black mist and attacked him!

Lu Cheng calmly waved his staff towards the group of monsters.

"boom!!"

The fireball exploded among the monsters and monsters, sending a large number of monsters flying away!

In his ears, system prompts also sounded one after another.

[Ding, you killed 11 elemental monsters (level 50), gained +20,000 experience points, and gained +51 source energy limit! 】

[Ding, you killed 9 elemental monsters (level 50), gained +280,000 experience points, and gained +69 source energy limit! 】

【Ding……】

The rewards for leapfrog kills are quite generous. On average, each elemental monster can provide him with more than 30,000 experience points!

He kept casting spells in his hands, but Lu Cheng had some doubts in his heart.

He climbed the mountain all the way and saw no trace of elemental monsters.

So where did these elemental monsters come from?

While thinking, he raised his staff, and thunderous rays of light gathered at the tip of the staff.

"Boom boom boom..."

Thunderclouds condensed, and streaks of lightning surged through the clouds.

Along with the lightning comes fierce wind!

He doesn't have any wind attribute skills at the moment, but Thunderstorm has both wind and thunder attributes, so it can be used as well.

A strong wind swept across the place, blowing away large swaths of black mist in a blink of an eye.

At this time, all the elemental monsters hidden in the fog were exposed!

Lightning fell and instantly killed each elemental monster!

"Ouch..."

Without the protection of the black mist, the elemental monster was at a loss, roaring and dodging the lightning.

And on the opposite side.

Looking at the group of monsters, Lu Cheng nodded slightly.

The number of these elemental monsters is at least two to three hundred.

Counting 10 broken crystals per monster, you can have two or three dark attribute source stones together!

But soon, he realized something was wrong.

In the center of the mountain top, a large hole was opened at some point, and streams of gray-black air blew out of it. It was extremely dense and hung in the air and condensed into black mist.

While he was watching, he saw an elemental monster climbing up the edge of the hole with its sharp claws and leaping out of the hole.

Looking over, Lu Cheng suddenly understood.

I see!

It seems that this big hole is the source of the black mist and elemental monsters.

So...are there more monsters in this cave?

Judging from the intensity of this dark attribute airflow, it is estimated that the possibility is not small!

Thinking of this, his mind became excited.

In the diary of the God of Luck, it was only written that dark attribute stone can avoid debuffs, but did not mention the specific amount needed.

He wants to search for source energy crystal nuclei in the Toya ruins, and his stay is expected to be quite long. The more prepared he is, the better.

While thinking in his mind, Lu Cheng kept firing out spells one after another.

As his skills continue to decline.

The surrounding elemental monsters fell to the ground in batches, and their numbers decreased rapidly!

Although elemental monsters continued to appear in the cave, adding to the group of monsters, they were not killed as fast as him!

With his current combat power, it is too easy to deal with these ordinary monsters, which is no different from mowing grass.

A few minutes later.

"boom……"

[Ding, you killed 10 elemental monsters (level 50), gained +50,000 experience points, and +1 source energy limit! 】

After killing the last few monsters, Lu Cheng put down his staff and looked around.

At this time, around him, there were corpses of elemental monsters everywhere.

"The harvest is good."

Lu Cheng nodded secretly.

The number of these elemental monsters is close to three hundred, providing him with more than 9 million experience points.

However, the main gain is the dark attribute source stone!

His mind turned and he looked at the storage space.

In his storage space, thousands of broken crystals are neatly arranged, giving a different sense of order.

These were all picked up by the metal flower spirit.

This little thing seemed to have an irresistible interest in collecting loot. He couldn't wait for the battle to end and picked up a lot of broken crystals.

At this time, the metal flower spirit just flew back with the last batch of broken crystals.

[Ding, you got Source Stone Crystal Shards (Dark Attribute) x120. 】

After placing these broken crystals neatly, the metal flower spirit stopped on Lu Cheng's shoulder, looking very satisfied.

[Origin Stone Fragments (Dark Attribute): Quantity 3101]

Looking over, Lu Cheng felt satisfied.

The harvest from this battle was quite good.

More than three thousand broken crystals are equivalent to three complete dark attribute source stones.

Then, he walked towards the previous row of stone pillars.

The hole looks quite shallow, so it may take some time to go back and forth.

It’s not too late to collect this batch of rock, iron and sand before exploring.

Arriving in front of the stone pillar, Lu Cheng quickly took action.

On the side, the metal flower spirit also flew down, hessing, hessing, hessing, carrying the rock iron sand with all his strength.

Fortunately, these rock iron sands are only attached to the ground and are not firm. It can barely handle it, but it is a little difficult.

[Ding, you get 1 unit of rock iron sand. 】

[Ding, you get 1 unit of rock iron sand. 】

…

Listening to the system prompts, Lu Cheng felt comfortable.

This is one of the benefits of exploring the Demonic Exile.

If he were in the outside world and wanted to find Yantiesha, he would have to wipe out several monster forces, but he might not be able to gain anything.

But in this secret realm, this kind of one-turn material is not so scarce.

If you have enough time, you might even be able to find the spirit wood core!

By then, the five special materials for building the city have been gathered.

Thinking in his mind, Lu Cheng acted quickly.

One person worked together and collected a lot of rock, iron and sand in a short time.

But at this moment, a golden light suddenly burst out on the ground nearby!

The metal flower spirit had just picked up a piece of rock iron sand, and was startled by the golden light, and fell to the ground with a thud.

"Um?"

Lu Cheng turned around and looked.

As the rock, iron and sand were continuously taken away, two small pits were sunk into the surrounding ground.

And this golden light comes from the pit in front of the metal flower spirit.

Looking over, Lu Cheng couldn't help but raise his eyebrows.

This golden light comes from another special material!

…

[Rock gold sand: a secondary material used to construct buildings, which can greatly increase the firmness and at the same time give the building a certain self-healing effect. 】

…

"Rock gold sand?"

After seeing the attributes clearly, Lu Cheng's heart moved.

This is a second-level material with earth attributes, which is one level higher than rock, iron, and sand.

Building a city only requires one turn of materials, and these two turns of materials are used in subsequent city wall upgrades.

It's a good thing that it can be found here.

As his mind turned, Lu Cheng quickly moved to collect it.

On the side, the metal flower spirit patted its butt and stood up, also coming to help collect it.

After a few minutes, the two materials were collected.

More than 300 units of rock iron sand and 200 units of rock gold sand are neatly stacked in the storage space.

During this period, elemental monsters occasionally sprang out of the cave, but fortunately, Lu Cheng killed them all in time without delaying the collection progress.

"Done."

After collecting the rock iron sand, Lu Cheng straightened up and breathed a sigh of relief.

Next, let’s see what harvest this cave can bring him!

With this in mind, Lu Cheng walked towards the cave.

But not far out of the cave, he realized something was wrong.

The light in the Demon Exile was already dim, but once you entered the cave, it should have been pitch black.

But in this cave, although it is not bright, you can vaguely see things clearly.

And... although the cave is winding and winding, the corners are very gentle and spiral downward, like a winding road inside the mountain.

"Is there any mystery in this cave?"

Lu Cheng's heart was filled with anticipation.

With his current combat power, monsters around level 50 would hardly pose a threat to him.

Unexpected situations mean unexpected gains!

Immediately, he quickened his pace and headed deeper into the cave.

Not long after, they had advanced a long distance.

"Hoo...ho..."

As he gradually went deeper, he could vaguely hear the roars of a group of animals deep in the cave.

Listening to the beast's roar, Lu Cheng raised his eyes.

This beast's roar was familiar to him. It came from elemental monsters.

However, something is wrong!

Now this beast's roar is not only very long, but also a little too neat!

This situation seems to be...

Many elemental monsters were organized and roared in unison in an orderly manner!

"Could it be that... there is a pure-blooded demon in this cave?"

Lu Cheng guessed, his eyes gradually lit up.

Elemental monsters have no intelligence. Even the BOSS among elemental monsters cannot command other monsters.

But if it were a pure-blooded demon, it would be different!

Pure-blooded demons can naturally suppress other demon subspecies, and they are easy to drive.

This probability seems quite small!

Thinking of this, Lu Cheng felt hot.

The reward for killing a pure-blooded demon is quite generous!

Immediately, he quickened his steps and headed deeper into the cave.

…

A few minutes later.

Lu Cheng stopped.

In front of him was a corner with light coming from the other side.

The roars of the elemental monsters came from it, and they were extremely real.

"This is it."

Lu Cheng took a deep breath and walked forward.

As he walked around the corner, his eyes suddenly lit up.

"This is?"

Lu Cheng couldn't help but be surprised as his eyes swept over the scene in front of him.

What he saw was an extremely huge cave, as if the entire stone mountain had been hollowed out.

In the center of the cave is a giant statue.

Around the statue, countless elemental monsters were prostrate on the ground, looking extremely pious.

In front of these monsters, a pure-blooded demon was surrounded by black flames and uttered syllables intermittently.

Every time he opened his mouth, many elemental monsters roared.

"I see."

Looking at this scene, Lu Cheng suddenly realized.

The beast roars he heard earlier were the elemental monsters being driven by demons to worship the statue.

After looking at it, he felt happy.

There are at least thousands of elemental monsters in the cave, and the experience alone is a huge sum.

And... there are also dark attribute stones and a pure-blood demon!

Pure-blooded demons in the Demon Exile are guaranteed to be Bronze level.

If it is slightly stronger, it can reach the silver level.

The harvest from this trip is probably quite amazing!

only……

Looking across the statue, Lu Cheng couldn't help but laugh.

The god carved in this giant statue looked very familiar to him. He was the demon god!
