"Uncle Ghost, are you a miner?" Tan Chu asked suspiciously.

He handed over a junior shovel, wanting to see how mining was done here.

"I learned a life profession at random, and I have never mined, and if the veins here are too advanced, I can't dig them." The Night Ghost smiled.

There are only two kinds of ore veins that can be collected by a junior miner, that is, chalcopyrite and black iron, and the higher the grade, it will exceed his mining range.

"Okay, you try." Tan Chu nodded.

The environment here is indeed the same as the original mine, but to say that this is a mine, he can't believe it...

There's no reason for the system to hide the veins in such a mysterious map, right?

The night ghost smiled and took the mining shovel handed over by Tan Chu, and began to pound on the stone wall in the surprised eyes of everyone...

Ding!

As sparks splashed in the dim stone cave, a large piece of black ore fell from the stone wall!

Damn, it's really a vein!

Seeing this, everyone understood that this was indeed a lump mine...

Moreover, the grade of the veins here is not low, and as soon as you shovel it down, black iron ore will appear.

Tan Chu stared blankly at the black metal glittering ore on the ground, and suddenly his eyes widened in surprise...

He quickly picked up the black iron ore and began to check its properties.

Black Iron: Quality 2, Crafting Material for Blacksmiths...

．．．

Nima, it's ore anyway!

Tan Chu looked at the huge cave in front of him excitedly, and his heart was extremely excited!

He understood that the mine cave hidden in the mysterious dungeon beneath the ground must be a higher-grade ore vein!

Just at the exit, there are black iron veins, so if you go inside, isn't it a more and more advanced mine?

"Brother, I guessed right, this is really a mine." The Night Ghost laughed.

"Well, I know it, this place must be protected!" Tan Chu replied excitedly.

Looking at the black stone wall in front of him, he knew very well that this would be a hidden treasure in the future!

He was worried that he didn't have a suitable mine to train his miner level, and the map here gave him hope.

"Let's go in and have a look." The Night Ghost laughed.

"Which one should we go to the three caves?" Stygian Snow asked suspiciously, holding a red candle.

"It doesn't matter which one you go, the mine is accessible in all directions, and we will return to the final position after reaching the worst, as long as we don't get separated." Tan Chu explained.

"Then let's go to this cave in the middle." The Night Ghost laughed.

"Yes, Snow Beauty will give me the candle, and I'll lead the way." Tan Chu said.

Nightfall returned the candle to him, followed him closely, and walked towards the cave in the middle...

Tan Chu walked forward along the pitch-black cave, and at the same time, took out the positioning beads that had not been used up in the dark forest last time from the package, and dropped one at every fork in the road.

"What is this?" Nightfall asked strangely.

"Positioning beads, lest we get lost, and the large army will come in a while and mark the route." Tan Chu replied.

"My brother is really good, no wonder every time something good happens, you bump into it." The Night Ghost sighed with a smile.

Tan Chu smiled slightly, continued to hold the red candle in his hand, and explored the way forward.

On his system map, which was still pitch black at this time, only small white dots emitted by the positioning beads showed the path they traveled in a zigzag manner.

This mysterious dungeon is actually not shown on a map!

He marveled in his heart, and walked more carefully through the cobweb-like labyrinth...

Passing through the intricate caves, the stone walls on both sides are still pitch black, indicating that they are still in the mining area of the black iron veins.

However, Tan Chu knew in his heart that the magical effect of the positioning bead could tell him that he didn't have to take a detour, as long as he moved along a straight line, sooner or later he would find the location they wanted to go...

Ten minutes passed, and they traveled in the dark cave without knowing how far the road was, and the straight line formed by the positioning beads was no longer visible on the map.

But at the other end of the cave where they were now, a faint light flickered, and everyone was suddenly surprised...

"We're going to get out of it." Nightmoon followed behind her sister and exclaimed in surprise.

"Don't worry, you guys wait here, I'll go see if there's any danger first." Tan Chu said.

"No, I'm afraid of the dark, I'll go with you." Nightfall said, grabbing his arm.

"I'm dizzy, what kind of assassin profession do you play if you're afraid of the dark?" Tan Chu said speechlessly.

Everyone held back their laughter, looking at the coquettish Night Snow and the helpless Tan Chu, they all knew in their hearts that the delicate snow beauty had finally met the person she liked...

This Stygian Snow, who has the title of a goddess, is a little pepper that no one in the Styx Army dares to mess with.

Her superb operation skills, as well as her cold personality, few people generally dare to talk to her.

But today, seeing her actually coquettish in front of Tan Chu, everyone couldn't help but laugh out loud.

"Okay, you follow me, you can't make a sound." Tan Chu advised.

"I understand." Nightfall said with a smile.

"I'm going too." Nightmoon said suddenly.

Belch...

Tan Chu looked at the moon beauty behind him and couldn't help but be dumbfounded.

This is a sincere troublemaker.

"Yue'er, sister is going to explore the road ahead, you follow the eldest brother here." Styx said softly.

"Yue'er, don't make trouble, the beast brothers are going to explore the way, and they will be back in a while." Cangfeng said speechlessly.

"Okay, you guys come back early, I'm afraid of the dark." Styx Moon looked at the red candle in Tan Chu's hand and said aggrievedly.

"Let's go." The dark night snow finally appeased the girl and immediately urged.

Tan Chu held the Divine Candle in his hand, carrying the night snow, and quickly rushed towards the other end of the cave...

He knew in his heart that the light in front of him might be the end of this cave, and the boss he was looking for might be there.

The two of them ran quietly and quickly, and soon rushed to the end of the cave, hiding behind the stone wall.

Tan Chu quietly stretched out his head and looked out of the cave...

The environment outside the cave suddenly made him nervous!

I saw that the cave was connected to a spacious hall, and on the stone wall of the hall, several silver-white stones were hung...

These silver stones are like light bulbs, emitting a soft light that illuminates the entire stone hall.

The light they had just seen from the cave was emitted by the silver ore on the stone wall.

But what surprised them even more was that in this stone hall, a large group of monsters were walking around, guarding this place like guards!

On the other side of the hall, through the dense horde of monsters, a pitch-black hole stretched out beneath the cavern...

"Beast, is this the end of the first layer?" Stygian Snow asked.

"Seems so, but these monsters are not easy to deal with." Tan Chu said softly.

Inside the spacious hall, hundreds of monsters gathered together and kept walking around, completely blocking the road to the cave on the other side...
