After unlocking the first node of Dragonblood and Rush's Dragon's Blood ability, the fog behind the tech tree cleared a bit, revealing the second node of the line.

They have been shown to consume more dragon blood crystals to unlock to further increase the concentration of dragon blood in their bodies, thus increasing the strength of dragon power skills.

This made Ji Chen's heart a little nervous, thinking about where to find a giant dragon to trade.

Dragons are greedy for money, but he happens to have a huge amount of gold coins, and this wealth makes dragons excited.

You bleed, I pay, it's fair.

But to get such a deal, he still has to continue to improve.

Otherwise, according to the same level of greed as the dragon and the natural greed for money, seeing them so weak, let alone trading.

It is estimated that they will directly greet them with a mouthful of dragon breath, easily kill them, and directly snatch the gold coins.

And if the strength is enough, he doesn't mind being a dragon slayer warrior once... After all, more dragon blood is obtained by slaying dragons.

Ji Chen and the others approached the lake again, and this time no monsters jumped out, stretched out their hands to condense a "water path" on the surface of the lake, and the group crossed it very smoothly.

Before coming to that huge cave.

Looking at the all-view map, you can see that there are no monsters or animals inside, not even the animals that have since invaded the area.

Even though the dragon was gone, the scent and traces it left behind still intimidated other creatures.

So far, Ji Chen has never seen a monster that can escape the detection of the all-seeing crown, so he also walked in with great confidence.

After a brief period of darkness, the eyes suddenly opened up.

Compared to the cave entrance, the interior of the cave is more spacious, about hundreds of meters long and wide, and tens of meters high.

The interior is not dark, there are a large number of glowing plants growing on the ground, on the rock wall, and on the top of the cave, and the faint blue light illuminates the entire cave as if it were day, which actually looks a bit mysterious.

The ground looks like it's been deliberately tended, and it's quite flat and regular, even if you can play football on it.

In the middle was a large rocky platform where the dragon slept.

Something was faintly visible in the dirt around the stone platform, and in the corner of one side were piles of skeletons as high as mountains, presumably creatures that had been caught by the dragon to fill their stomachs.

I don't know why, it's quite cold outside the cave, which is hundreds of meters high, but inside the cave is as warm as spring, as if there is a fire burning continuously.

Ji Chen didn't think much about it, but sighed that the dragon was really good at finding a nest.

Looking at the bare cave, a trace of disappointment flashed inexorably in his eyes.

I saw that the dragon had already transferred most of its treasure before leaving here.

All that was left was leftovers buried in the dirt.

But it's slightly better than nothing, maybe the dragon has seen something wrong and missed something?

"Half of the Naga warriors are stationed at the entrance of the cave to prevent any targets from approaching."

"The rest spread out in search of anything of value."

Hearing this, half of the Naga warriors who were pointed out by Ji Chen immediately turned around and left, returned to the entrance of the cave and became vigilant.

The rest scattered and searched everywhere.

Use the bone blade or trident in your hand to pry up the top layer of dirt and sweep away the fluorescent plants to see if there is anything buried underneath.

The cave suddenly became a construction site, and there were potholes dug everywhere.

As soon as I dug up, I dug up a lot of things.

Scattered gold and silver coins, chewed broken bones, broken weapons and armor...

It seems that there are also many dragon slaying warriors, who have been chewed up by the dragon.

"My lord, I found a dragon scale!" Not far away, Anina, who was interested in joining the excavation army, suddenly picked up a palm-sized scale and said excitedly.

Ji Chen walked over quickly and picked it up.

Take it in your hand and gaze at it.

【Falling Dragon Scales】

[Level]: 3-star treasure

[Uses]: It can be used as a forging material for weapons and armor

Good guy, just a detached dragon scale is a 3-star treasure, and it seems that the rumors that the dragon is a treasure are not false.

One after another, the army also discovered a lot of things.

A small amount of dragon scales, cloudy dragon blood mixed with dirt, dragon feces, etc., but there are no treasures such as dragon claws and dragon blood crystals.

This made him sigh again.

It's really scraped clean, and there's not even a whole thing.

An hour later.

Looking at the bones everywhere, broken weapons and armor, and feces bigger than a skull, but with only a few dozen dragon scales and more than a hundred gold and silver coins, Ji Chen completely lost his patience.

Directly let the pure water sea elf shoot water arrows towards the ground.

A powerful arrow of water plunged deep into the ground and exploded, blasting the soft earth into the sky, and falling with the feces and broken bones in the sky.

Such a violent excavation method quickly plowed the nearby soil and lowered the height by half a meter.

Another round of water arrows exploded.

But this time, a whole thing exploded.

A door panel, ah no, a greatsword that looks like a door panel.

The giant sword was broken two-thirds of the way through the blade, and the tip of the sword was gone.

He gave the order to stop the bombardment, walked over, and tried to pick up the greatsword.

But the greatsword weighed far more than he had imagined, and it didn't move like moving a rock.

Ji Chen's heart suddenly became energetic, and he used mana to bless the strength of his hand, and reluctantly lifted the giant sword out of the dirt and inserted it on the ground.

The sword is cross-shaped, with a ruby in the center, and a lifelike two-winged dragon engraved on the broken body, the blade of which is so sharp that it breaks its hair, even when buried deep in the earth.

Even if Ji Chen didn't know anything about swords, he could know that this was a rare divine weapon.

Get your heart pumped and check out its information panel.

【Dragon Slayer Greatsword (Fractured State)】

[Level]: 5-Star Treasure (Monomer)

[Effect]: 1 Increases the damage of dragon creatures by 50% 2 The stronger the user's strength, the more lethal 3 the user will be more vulnerable to dragon creatures' hatred

[Dragon Slayer Lyons Kuka's sword, killed during the crusade against the dragon, and his sword was broken in battle]

5-star treasure, dragon slaying sword... Ahh

This is still a level in a broken state, and it is conceivable that when it is repaired, the level will become even higher, and it is not impossible to become a 6-star or even 7-star treasure.

With such a heavy sword, not many people can use it intact.

Anina's eyes were already shining, and she was crisp: "My lord, can you give me this big sword?" ”

Her greatsword had been damaged in battle, and she was missing a new weapon to work with.

Ji Chen smiled and gave up his position.

Seeing this, Anina couldn't wait to come over, picked up the big sword with one hand, and waved it in her hand at will, crackling and shattering the skeletons piled on the side.

It's like a child on the way to play, and he found a wooden stick that is worth his hand.

Although this stick is a little longer than her height.

Seeing Anina beating bones flying around, Ji Chen made a voice to tell her to stop.

Anina stopped, looked at the mess around her, and immediately touched her head in embarrassment.

After some searching, he dug up the broken tip of the dragon slayer sword in the nearby soil.

Now, as long as you find a good enough blacksmith, you can repair this greatsword and exert its strongest power.

With this harvest, Ji Chen's spirit also perked up and ordered to continue digging.

This time it's the Dragon Slaying Sword, maybe the next one will be the Heavenly God Sword.

Once again, the cave was being dug in full swing

More than ten minutes later.

Knock –

A Naga warrior thrust his bone blade into the dirt, and there was a metal clash.

Ji Chen's eyes suddenly lit up.

Probably dug up something.

Immediately let a few Naga warriors work together to dig out the soil.

Soon a bright color was seen.

Ji Chen squatted down, pinched the strip with the thickness of his middle finger, put it in the palm of his hand, and then brushed away the dirt on it.

This is a key, the texture is unknown.

But there is a strange light on the outside, and it always looks familiar.

After looking at it for a while, he suddenly realized.

This outward glow has been seen from treasure chests.

Ji Chen must have guessed a possibility in his heart, could it be that this is...

When even viewing its information panel.

【Four-Star Chest Key】

[Level]: 4-Star Treasure (Special)

[Effect]: Able to open locked treasure chests with a level of no more than four stars

【Lady Luck's Gift】

Treasure Chest Key!

Ji Chen was ecstatic.

Because deep in the rainforest of the main island, under that water-filled patio, there is a locked four-star treasure chest!

You have a key to open it!

I didn't expect to accidentally find it here, which can be described as an unexpected joy!

Mei Zizi received the key to the backpack, and he planned to go to the patio to open the treasure chest as soon as he finished exploring the dragon's lair.

Four-star treasure chests can at least produce things similar in value to four-star treasures.

If there is a big explosion of character, maybe there will be some legendary items, legendary weapons and the like.

For such a thing as fighting luck, Ji Chen is not false at all.

Up to now, the two dragon slaying swords and the four-star treasure chest key, which can be called treasures, have completely made him excited.

Let him decide that he will never leave if he doesn't dig three feet into the ground today!

Digging from morning to evening.

The third treasure is freshly baked.

An irregular yellow object two or three meters long.

It's a bit rough to the touch and smells very pungent.

【Sulfur】

[Level]: Level 3 resources

It turned out to be sulfur!?

Ji Chen looked surprised.

Sulfur, like Mithril and Adamantite, is a Level 3 resource, and its preciousness goes without saying.

Such a large piece of sulfur is equivalent to at least forty units.

But what puzzled him was why there was such a resource as sulfur in this place.

Could it be that the dragon brought it back from outside?

But the sulfur looks very bad, and the smell is very pungent, so it probably won't arouse the interest of the dragon, right?

Just when he was puzzled.

The army digging on the other side, suddenly reported.

"We've dug up a yellow object from here, too."

Ji Chen frowned, walked over and took a look.

It's also sulfur, but this one is even bigger, equivalent to eighty units.

Coincidentally.

The armies digging around were digging out the sulfur one after another.

The small ones are a few units large, and the large ones are hundreds of units.

It's like there's a sulphur vein underneath... Wait, sulphur veins!?

Ji Chen suddenly hammered his palm, and suddenly realized.

Why can't there be a sulphur vein underneath?

At this time, a discordant report came from the other side.

"My lord, we seem to have dug up diamonds."

When I looked over, I saw a transparent diamond in the dirt, the size of a fist.

If this is placed in Blue Star, it won't be worth hundreds of millions?

But unfortunately, in this world, diamond is only a low-level resource, and it is about the same value as copper.

What he really cares about is, why are diamonds produced here?

Suddenly, Ji Chen's heart was shocked.

He remembered that things like diamonds seemed to only be found in volcanic areas, and since they appeared here, didn't that mean that this was... A volcano?

If you explain it this way, then the appearance of this sulfur also makes sense!

Volcanoes are rich in minerals such as sulfur and diamonds.

All the way, all the way.

The temperature of this cave is easy to explain from the outside, and there is a volcanic crater underneath the cave.

In a volcanic eruption, magma carries minerals down the mountain to the summit, or simply the mountain or even the entire mountain in the northeast, or even the entire island, is the product of the eruption.

This oil explains why there are so many mineral resources under this mountainous area.

It all started with that raging volcanic eruption.

Thinking of this, Ji Chen suddenly felt that the minerals in front of him were not fragrant.

Although the geology of the Crescent Islands now looks quite stable, the thought that their territory is near a volcano makes me feel like a ghost.

Maybe one day the volcano will erupt again?

He can run, but he can't run the territory.

I don't know if I thought about it, but the ground under my feet suddenly began to tremble slightly.

The cave was pouring some dust.

It looks like the ground is shaking.

Ji Chen's face suddenly changed drastically.

Isn't it, sir, when you think about it, you really come?

Before he had time to think about it, he immediately ran down the cave with his army at a sprint speed and rushed towards the way down the mountain.

But before they could take a step down the hill, they shuddered and stopped as if they had never appeared.

Everyone was at a loss.

"My lord, what should we do now?" Alice asked in a low voice.

Ji Chen groaned, but chose to stay at the top of the mountain first and wait until dawn tomorrow before going back.

It was getting late.

Originally, it was quite difficult to go up the mountain, and if they had come down when the mountain was black and numb, I am afraid that before the volcano erupted, they would have fallen off the cliff and died.

So, they went back to the cave and began to set up camp.

The cave was warm and sheltered from the wind and rain, his back was packed with enough food, and the lake outside the cave had fresh water.

So you don't have to worry about hunger and cold.

On it together
