After about three or four hours, Nie Fan synthesized three runes-guard, and there were also a lot of broken rune stones, plus the ones that exploded before, there were thirty or forty pieces.

There are a lot of repetitions, Nie Fan was dazzled, and after a careful search, Nie Fan found that he actually pieced together another rune-exemption, and his luck was not bad.

The remaining rune stones seemed to be fragments of rune-elemental, rune-life, rune-guardian and rune-immunity, and the remaining two rune stones were not even fragmented. It seems that the red-robed undead caster can't get together the remaining two rune stones alone.

Walked forward for a distance, and a large number of red-robed undead spellcasters appeared in the aisle in front of him, there were six or seven of them, Nie Fan hesitated for a moment, and then retreated, let's brush outside for a while, there are so many red-robed undead spellcasters, it is not something that he can deal with.

The fourth floor of the mine is still full of rivers, like spider webs, crisscrossed and crisscrossed.

Nie Fan thought for a while, he might be able to go deep into the deepest part of the fourth layer of the zombie mine along the river, but the refreshed number of red-robed undead spellcasters on the fourth layer of the mine made Nie Fan a little worried, and it should be a very dangerous thing to enter the depths of the zombie mine.

After swiping for a while, a crisp system prompt sounded, and Nie Fan glanced at his level and upgraded another level.

Finally thirty-one.

After staying in the zombie mine for so many days, Nie Fan's current level is not particularly high among players, if he can't explore the inside of the zombie mine, it's no longer interesting to continue to stay here, the upgrade is not particularly fast, and he can't get new rune stones. I didn't know how dangerous it was inside, and after hesitating for a moment, Nie Fan decided to take the risk and give it a try!

In various ways, as long as you can enter the depths of the fourth layer of the zombie mine, you can do it.

The big deal is to hang up the first level, if you haven't even been to the depths of the fourth layer of the zombie mine, you will definitely regret it in the future.

Nie Fan walked to the edge of the river, activated the transformation seal skill, jumped down, poof, splashing, he was like a nimble swimming fish at the bottom of the water, swimming along the current towards the depths of the zombie mine.

After diving forward for five minutes, he poked out of the water and saw that there were more than a dozen red-robed undead spellcasters densely packed on the riverbank, and after some found him, a large fireball technique shot towards him, Nie Fan was startled, immediately dived back into the water, continued to dive forward, and after another three minutes, he finally found a place where there were no monsters, went ashore, transformed back into human form from a seal, thought about it, turned into a werewolf again, and continued to grope ahead.

He didn't know where he was anymore, the maps here were unknown, and he had to drill around like a headless fly.

Five red-robed undead spellcasters were wandering in front, and Nie Fan started sneaking and slowly touched them, preparing to bypass them.

Keeping a distance of more than three yards from those red-robed undead spellcasters, Nie Fan slowly walked forward, and just as he was about to get rid of those red-robed undead spellcasters, a red-robed undead spell caster seemed to have discovered something, and a strange cry came out of his mouth, and with a wave of his staff, a large fireball shot towards Nie Fan.

It's over, it's been discovered! Nie Fan's heart jumped, sprint!

He started to sprint, his movement speed suddenly increased, and he ran wildly outside.

A series of big fireballs shot towards Nie Fan, and Nie Fan hurriedly blessed himself with a guard, and the speed was still unabated, during which he poured another bottle of acceleration potion.

Those red-robed undead spellcasters followed closely behind Nie Fan.

Just as Nie Fan was running away, three more undead spellcasters appeared around the corner in front of him, and he suddenly had a bitter face, and the roof leak happened to rain overnight, and he actually got into the monster pile.

There can be no momentary hesitation.

Pounce!

Nie Fan suddenly pounced and pounced on a red-robed undead spell caster in front of him, and this one jumped more than three yards away.

Bang, Nie Fan swooped down and hit the red-robed undead spellcaster.

It's a flame clone!

However, Nie Fan was not ready to kill him, and now fighting with these red-robed undead spellcasters was an act of seeking death! The swoop skill needs to have a target before it can be cast, and Nie Fan is just using him to increase his speed.

Several fireballs shot towards him, and Nie Fan jumped over the head of a red-robed undead spellcaster, and rushed forward.

Five magic spells hit Nie Fan in a row, directly knocking out Nie Fan's more than 1,000 HP, Nie Fan quickly used the rune-life, and the HP returned to about 50%.

Two more fireballs shot at him.

Escape!

Bang bang, two magic bolts fell on Nie Fan's body, but they didn't cause any damage to Nie Fan.

Nie Fan suddenly disappeared, and those red-robed undead spellcasters searched for it, but found no trace of Nie Fan, and then slowly dispersed.

Nie Fan hid in the corner, and when he saw those red-robed undead spellcasters disperse, his hanging heart was relaxed, and he continued to wait quietly until all the skills cooled down, then he turned into a cheetah and continued to sneak inside.

This fourth-layer dungeon of the mine cave requires an elite team of at least twenty or thirty people to pass through, and Nie Fan dared to break into it alone, which can be regarded as very bold, and he almost hung up several times.

In the depths of the dark mine, there are crises everywhere, Nie Fan has searched for a long time, but he has found nothing, and he can't help but be a little disappointed, is there not even a boss here?

It's a little unwilling.,At least you have to see a boss before you go!

Although Nie Fan couldn't get the boss here, he had been in the depths of this mine for more than an hour, and he only found some small monsters, which was too depressing.

After searching for more than half an hour, Nie Fan finally found something amazing, there were some artificially carved traces on a passage he passed, a layer of stone bricks was laid on the ground, and he walked along the aisle towards the inside, and found that it was a very wide space, about 100 yards in radius, and in the center was a tall skeleton, it was completely black, and a pair of bone wings grew on its back, looking towards its chest, I saw a five-star pattern on its chest, as well as those six runes.

It walked back and forth, as if guarding something, and there was a blue ball of light floating in the center of the hall, and something was silently floating in the center of that blue ball of light.

Check out its rating.

Necro Inquisitor: Level 35, big boss, 37000/37000 HP.

Big boss-level monster, Nie Fan couldn't help but feel a little depressed, it was very difficult to kill this undead judge, did he want to find someone else to form a group to kill it?

Nie Fan was silent for a moment, the fourth layer of this zombie mine cave cannot be known to others, not to mention the rune stones on the fourth layer of the zombie mine cave are very valuable things, if many players come in, then soon the rune stones, which are now very scarce, will become stalls everywhere. And now, he can get a rune stone or two and put it up for auction on the market, and he can sell it for the price of a piece of black magic bronze-level equipment. Moreover, the power stones produced in the zombie mine cave do not know how to use them for the time being, and if they can be used, these things will be very precious.

If he can know how to use the power stone, Nie Fan can find a few low-level players to help him mine secretly, if it is exposed, then the fourth layer of the mine will no longer be a secret.

Even if he didn't kill the Undead Inquisitor, he couldn't leak the secret of the fourth layer of the mine, and in just a moment, Nie Fan had already made up his mind.

Looking at the suspended blue light in the center of the hall, he didn't know what it was, after thinking about it, he stayed quietly in place, patiently waiting for the transformation cheetah skill to cool down, and after more than ten minutes, he turned on the transformation cheetah skill and slowly sneaked towards the center of the hall.

The Undead Inquisitor didn't stand still, it wandered back and forth, its wings flapping endlessly, but it had no intention of flying.

Patiently waiting for the opportunity, getting closer and closer, only about ten yards away from the blue light, Nie Fan paused as he saw the Undead Inquisitor walking towards him.

Nie Fan didn't dare to move, seven yards, six yards, his heartstrings were tight, as long as there was something wrong with the undead judge, he could only fight hard.

The Undead Inquisitor was three yards tall, with black ribs and a skull, giving a heavy sense of oppression. If he was discovered by the Undead Inquisitor, Nie Fan didn't know if he could run away.

It stopped, as if it hadn't noticed anything, looked around, and then patrolled in another direction.

Seeing the Undead Inquisitor gradually walking away, Nie Fan exhaled softly and approached the blue light, he saw a scroll suspended in the blue light, but the light was too dazzling for him to see clearly.

It won't be long before the Undead Inquisitor will be over, no matter what! Nie Fan thought that death would be death, and his right hand reached over and scooped up the scroll in his hand, only to see the blue light pause.

The moment he got the scroll, Nie Fan turned around and ran, sprinting!

At this time, as long as you can run out, you will earn it!

The Undead Inquisitor suddenly turned around and found that Nie Fan had snatched the scroll, let out a deafening roar, and pounced on Nie Fan, and a black lightsaber quickly conjured up in his hand, and the black sword light slashed down.

With a loud bang, the sword light slashed down on the ground, and the ground suddenly sank into a deep pit!

Nie Fan jumped away, he was startled by the incredible power of the Undead Inquisitor, how dare he stay in place, use up a bottle of acceleration potion, and run wildly.

Another sword light slashed down, almost on the head, Nie Fan couldn't escape at all!

Seeing that he was about to die on the spot, Nie Fan escaped, just blocked the attack of the undead judge, and his body rushed forward, burrowing into the cave next to him, the cave was very complicated, there were many complex caves above his head, and it seemed to lead to the third layer of the mine.

Nie Fan's body quickly transformed, turning into the shape of a falcon, and his body flew up sharply, flying towards the complex cave above.

The undead inquisitor rushed out, looked around, didn't find Nie Fan, looked up, and found that Nie Fan turned into a falcon and flew away, the wings behind him vibrated rapidly, and rushed towards Nie Fan.
