The deep cavern of the mine became more and more forky, leading in all directions, and the ghost led the way, and turned a few corners to a fairly open hall.

The hall is full of open-pit ore, but because the location is deeper, the light is more dark, so people can't see it clearly.

"Look, that's the guy!"

The ghost shouted as he pointed to a slightly shaky black shadow in the corner ahead.

It was a monster that looked like a black iron ore, a little smaller than a football, and it was not easy to find without the guidance of a ghost.

The ghost didn't notice the monster at first, but it came to the hall and attracted all the black bats around it, ready to blow it up.

As a result, after the self-detonation, the ghost found that there was a small black monster that had not been blown up by it and had not lost much blood, and after a closer look, he remembered what Mo Hai had said to it and asked it to find this monster.

"Sure enough, it's a black stone worm!"

Mo Hai looked at the little black monster who was munching on the ore in the corner, and his heart was happy.

If he didn't find the Black Stone Worm in this mine, he would have to run a long way to another cave in the quicksand mine to try his luck.

"Surround and kill, be careful not to let it run away."

Mo Hai commanded his subordinates, and a group of people scattered around him.

It's also a shame that they are monsters, and if the player Black Stone Worm had been scared away, it would have been scared away.

The body of the black stone insect is like an ore, it is different from hiding, and its escape speed is superb, so it is not easy to catch up with it in the mine.

"Roar!"

The Black Stone Worm sensed that Mo Hai and they were surrounding him, and it turned around and roared at Mo Hai and them, warning Mo Hai that they should not approach again.

Seeing that Mo Hai and the others didn't listen to the warning, the black stone insect was furious, a look of anger appeared in his eyes, and his body swelled several times violently.

Bang!

One mouth, and a piece of ore erupted from its mouth.

"Fence it out."

Mo Hai ignored the attack of the black stone worm, and he took the lead in rushing over.

It seems that the black stone worm treats monsters differently than the player, if it sees the player, it will run away as soon as possible, and it will choose to attack if it can't escape.

And the attack damage of the black stone worm is not high, and there will be no danger if the mining players with poor equipment encounter it, let alone the elites of Mo Hai and them.

However, Mo Hai didn't dare to underestimate the black stone worm, the black stone worm will activate the skill when the blood volume is small to a certain extent, its skill is not a damage skill, and the player is okay if it hits, but it is fatal to Mo Hai and them.

The black stone worm's HP quickly dropped to 80%, and as soon as the light flashed in its mouth, it was about to activate its skills.

Mo Hai had already prepared, and before the Black Stone Worm skill was activated, he knocked it down with a stick, interrupting the Black Stone Worm skill.

The Black Stone Worm skill doesn't do any damage, but the target it hits will be transferred out to the quicksand open space outside.

At most, the player will take a little time to run back, and Mo Hai and them will be beaten to death if they are alone.

After 80% HP, for every 10% decrease in HP, the Black Stone Worm will launch a skill attack.

The black stone worm is a special monster, does not eat hatred, although it is not an elite template, but the blood volume is higher than that of the elite of the same level, the giant sand wolf at level 18 is only 20,000 blood, and the black stone worm at level 15 has 30,000 blood.

The player fights the black stone worm, and it is impossible to say that a few people will move out of the mine, but they are surrounded by more than a dozen bandit leaders, and the black stone worm is beaten to death without releasing a skill.

If the player kills the Black Stone Worm, the Black Stone Worm will explode a large amount of ore, but if it dies at Mo Hai's hands, the Black Stone Worm does not drop anything.

However, Mo Hai didn't care, under his gaze, the corpse of the black stone insect gradually melted, and the ground corroded into a pitch-black hole the size of a person.

"What is this?" The ghost was a little surprised to see it.

The edge of the cave glows faintly blue, but the inside is unfathomable, as if leading to somewhere else.

"I'll go in first, you guys come in, there are a lot of monsters inside, and you're ready to fight when you enter." Mo Hai didn't answer the ghost directly, anyway, he would know after going down.

After Mo Hai jumped, the ghosts couldn't wait to jump down, and on the 13th, they also jumped into the cave one by one.

"Strange, where does this lead to?"

After Mo Hai and the others all jumped in, the two Loli quietly appeared at the mysterious entrance of the cave and looked at the entrance of the cave curiously.

When Mo Hai and the Black Stone Worm were fighting, they had already sneaked back, and they wanted to wait for the opportunity to sneak attack, but they didn't expect the Black Stone Worm to be so weak, they didn't have the slightest chance, so they could only stand still.

"I don't know, let's go in too." Dongxue didn't think too much about it, her calves moved, and she jumped in lightly.

"Okay." Xia Guo was very curious, she had already had this idea, she jumped lightly, and the two jumped in almost at the same time.

After a short period of darkness, the vision of the two loli returned to normal.

"What a big mine!"

Xia Guo's eyes widened, and when he looked around, he saw them appear in the corner of a huge circular mine cave with a radius of nearly fifty meters.

As far as the eye can see, the floor of the huge mine is full of dense open-pit ore that emits a faint glow.

The bandit leader had retreated to the other corner of the huge mine, surrounded by a horde of monsters and fighting.

There are skeletons, bats, spiders, and rats, and the number of monsters seems to be a bit large.

But following all the way and being killed more than ten times, the two Lori took a look and knew that those monsters couldn't be the opponents of the bandit leaders, and they wouldn't have a chance to sneak attack.

And just as the two Lori expected, in less than ten minutes, all the monsters in the mine were killed.

If the two of them sneak past, they will probably be like those monsters.

The hole outside looked like it would disappear at any time, and the two Lori didn't dare to die as readily as before.

If the hole disappears, they won't have the slightest chance of completing their mission.

They just need to complete the task, and they don't care about the level. They have a lot of time to spend on this group of bandit leaders, this underground mine looks unusual, and there may be a chance to make a sneak attack, but there is really no chance to talk about it later.

Seeing that the leader of the group of bandits had already begun to dig the open-pit ore on the ground, Xia Guo and Dong Xue quietly discussed it and decided to wait for an opportunity while mining.

"Hey, sister, my mining skills have become level 1+1." Before Xia Guo waved the mine hoe with his small hand, he glanced at his mining skills, and then made an unexpected discovery.

"See, the map name here is 'Underground Mine EX-1 Floor', and there is a temporary buff of mining skill level +1." Dongxue is more careful than Xia Guo, she has already found out.

"This is good, we have to take the opportunity to mine more!" Xia Guo was suddenly eager to try.

The mine was obviously unusual, and it made her curious.

On the other side, Mo Hai was digging for high-level mines on the ground.

Their level 2 mining skills have become level 3 in the EX-1 floor of the underground mine, but the skill level experience is calculated according to level 2!

And the open-pit ore here is by no means comparable to the outer mines.

The number of copper ore and iron ore has been greatly reduced, the number of black iron ore has increased greatly, silver ore and gold ore can be seen at a glance, and there are even attribute ores such as cuprite and hematite!

This is the famous underground mine in the game, in the underground mine, the player's mining skills will have an additional buff level increase, and the quality of ore in the mine will be greatly increased!

The only way to enter the underground mine is to kill the Black Stone Worm, which feeds on ore.

The Black Stone Worm will only appear in high-quality mines, and it is usually only refreshed once a month or so, and after killing, a hole that can enter the underground EX mine will appear. Only 20 players are allowed to enter the cave, and when the number of people entering is full, the hole will be closed instantly.

There are very few mines that can refresh the black stone worm in the game, and the mine with the black stone worm will always be overcrowded, and it takes a burst of luck to enter it, many players have never had the opportunity to enter, and Mo Hai is now also the first time.

The scene inside the underground mine was even more spectacular than Mo Hai had ever known, with an astonishing amount of ore reserves, and the experience points of their mining skills began to soar.

But Mo Hai knows that this is just the beginning, and more powerful ones are yet to come!

It's only in the EX-1 level of the underground mine, but you can't collect the amber ore that Gavin needs.
