After falling rapidly for more than thirty yards, with a "poof", Nie Fan plunged into the water again, and a more than fifty point injury floated on his head, fortunately there was a puddle below, if it was a stone, it would really fall into flesh.

The water flow near here seems to be much smoother, and after estimating the height, it should already be the third layer under the Nelze Mine, and it will take at least three hours for the average player to advance from the first floor of the Nelze Mine to the third layer below, and there are countless mobs along the way, killing them endlessly.

Nie Fan determined his current position, looked ahead, the water flow was divided into five tributaries here, flowing in all directions, compared the map, he just swam towards a tributary on the left, it should be this one! Swimming forward in the dark river, it was pitch black in front of him, and he could barely see his fingers, but fortunately there were no monsters in the river, so he was safe.

The river in the Nierze Mine was crisscrossed, Nie Fan took a fork in the road several times, and the skill of transforming into a seal soon ended, he could only rely on swimming, and walked around the river for more than an hour, and finally found the right direction and kept the correct route firmly in his mind.

The speed of the river gradually calmed down, and a large flat ground appeared on both sides of the river, and thirty or forty zombie mages were standing, and they soon spotted Nie Fan swimming in the river, and fireballs shot in his direction.

Nie Fan was startled and plunged headlong into the water, bang, bang, and dense magic exploded on the surface of the water.

It's good to hide quickly, otherwise you'll have to be bombarded to pieces by these magics!

After diving forward for a distance, he finally dodged the zombie mages far away, and swam forward for a while, and it seemed that the front was already the end of the river, and above the river was a cold rock wall.

Is this place blocked?

However, the river marked on the map did not end here, and the flow of the river could be felt below, so he thought of something, plunged into the water, groped on the rock wall, and there was indeed a passage under the water! He got into it and swam forward for more than a minute, when he saw a bright light ahead of him, and then he came out.

After another five or six minutes of continuous swimming, Nie Fan finally arrived at the destination of this trip, which was a riverbank, full of rubble, scattered with countless corpses, like a mass graveyard, among the rubble, a zombie wearing tattered metal chain mail, three or four yards tall, dragging a huge hammer was limping back and forth, stopping from time to time, looking back and forth.

That's it, Zombie Overseer! A level 30 boss with 22,000 HP.

If you take the right path from the beginning, from the entrance of the dungeon to here, it is estimated that it will only take more than ten minutes, and the distance is not too far, if Lin Suyue and Xue Yu want to come here, it will not be so simple, at least a bottle of underwater breathing medicine is needed, and you have to pay attention to the dangers along the way, but it is not too much of a problem.

Nie Fan observed the terrain and looked into the distance, there was a huge crack on the rock wall fifty or sixty yards away from here, and his heart moved, this is there, it is a terrain that can be used.

He climbed up to the river bank from the corner of the rock wall, activated the transformation cheetah skill, and entered a stealth state, slowly approaching the direction of the rock crevice.

The zombie overseers seemed to have discovered something, and went back and forth.

Nie Fan slowed down, and the zombie overseer didn't notice him and walked into the distance.

After sneaking for a distance, Nie Fan finally came to the crack in the rock wall, the space in this crack is still quite large, it can accommodate up to five people, the entrance is very narrow, only one person is allowed to enter, with the fat body of the zombie overseer, he can't enter at all.

Use magic to lure the zombie overseer over, and just stand in the crack and output it with confidence.

This terrain is not very hidden, and after the dungeon is opened, I believe that players will soon find it, but this terrain bug is within the tolerance range of the server, so the server will not fix it.

If you follow the conventional method, from the entrance of the dungeon all the way to here, it will take three or four hours at the earliest, and there are many difficulties along the way, and the group will be wiped out at every turn, and this b0ss can be harvested without effort, which is equivalent to a reward for players.

Nie Fan happened to find a shortcut to get here in a short time through the complicated river channels in the mine, so that he could frantically farm the zombie overseers.

He couldn't help but feel a little excited in his heart, knowing that with such a method of farming zombie overseers, they could accumulate a lot of money in a very short period of time, and they had to earn a little more before the next update of the server.

According to Article 26 of the Regulations on the Administration of Virtual Games, the items obtained by players in virtual games are all private property, and the game company has no right to take them back.

In other words, even if the system finds a loophole and patches it, and repairs the items obtained by Nie Fan by killing the zombie overseer before, the game company will not be able to get it back.

Thinking of this, Nie Fan took a deep breath, calmed down his excitement, came out of the crack, and slowly approached the zombie overseer who was wandering around.

Small fireballs!

A fireball shot towards the zombie overseer, and with a bang, it exploded on the zombie overseer's body, and sparks flew everywhere.

The zombie overseer was attacked, roared violently, and walked towards Nie Fan with a huge hammer, this big man is very powerful, if it is according to the normal monster fighting mode, a team of ten level 30 players may not be able to deal with it!

Nie Fan quickly retreated, retreating into the rock crevice.

The zombie overseer swung the hammer in his hand and smashed it with a bang, smashing it on the rock wall, and the rubble powder fell down in a torrent.

Nie Fan, who was hiding in the stone crevice, was unharmed, no matter how the zombie overseer roared, its huge body could not squeeze into this narrow stone crevice.

Bloodthirsty Vines!

Nie Fan used a vine technique, and a vine grew on the ground, winding the zombie overseer.

"Smack!" "Smack!" The vines slammed into the zombie overseer's body.

System: The Bloodthirsty Vine skill is successfully released, and you gain 3 skill proficiency points.

Due to the relatively large difference in levels, Nie Fan's skill proficiency obtained by using the Bloodthirsty Vine Technique is quite considerable, and it seems that he can practice more skill proficiency here.

The zombie overseer swung the hammer and broke up the vine technique in just two clicks, and the sixth-level vine technique only caused two damage values of more than seventy points!

But it doesn't matter, in the face of a level 30 boss, this kind of damage is already very good!

The Zombie Overseer's HP is restored quickly, but ten minutes of continuous output should be able to get it done!

Nie Fan thought about it, and another black oil technique and a small fireball burst out in a row, and one by one fifty or sixty injuries floated up from the zombie overseer's head, and the zombie overseer roared angrily, swinging a huge hammer and smashing the rock wall constantly, although it was close at hand, it was never able to reach Nie Fan.

Under Nie Fan's continuous attack output, about eight minutes later, the zombie overseer's blood volume finally bottomed out, and he roared in the sky and fell to the ground.

Succeeded, it was easier than expected, Nie Fan thought with a smile, walked out of the stone crack, searched under the zombie overseer for a while, and picked up two things, a bronze gauntlet of a level 30 mage, and a potion, I don't know what it is.

Nie Fan took out a bottle and looked at it, the test tube-like glass bottle contained a green liquid, the mouth of the bottle was firmly sealed, and the green mist inside kept rising.

Primary Severe Corpse Poison Potion: Sixteen bottles, throwing damage, throwing hits the opponent can cause corpse poison damage to them, splash attack.

Like the Fierce Burning Elixir, this corpse poison potion is also used to throw, Nie Fan had a trace of expectation, the corpse poison elixir is higher than the Fierce Burning Elixir, and the effect is stronger.

That mage's bronze gauntlet, +21 spirit, +12 mana, can also be sold for a good price, after all, bronze equipment is still quite rare now.
