After teaching Davina some tricks on how to maintain the highly poisonous corpse flower, Nie Fan came out of the manor and continued to go down to the zombie mine.

Although it is faster to make money in the zombie mine, as the level increases, the experience points obtained by killing zombie overseers gradually decreases, and the upgrade speed is relatively slow, after all, most of the time is wasted on the road. However, compared to farming ordinary monsters in the wild, the upgrade speed of Nie Fan and the others is still relatively fast.

Browsing the forum, it is said that the elite groups of the major studios have already hit the seventh boss on the third layer of the zombie mine, and the zombie overseer is only the fifth boss, and there are eleven more powerful boss-level creatures behind.

Their progress was much faster than Nie Fan imagined, after all, they were a team of dozens of elite players, and their strength should not be underestimated.

Brush to level 30, Nie Fan is going to change places, although it is very fast to make money here, but after reaching level 30, the upgrade speed is very slow, if the level is too big by others, it is useless to make more money, not to mention that after his manor is on the right track, the speed of making money is much faster than when he farms monsters here!

After killing the zombie overseer for the sixth time, Nie Fan also exploded into a strange item, which was a piece of broken leather, I don't know what material it was, it was very tough, and some complex road maps were depicted on it, as if it was a map, and I took a look at its attributes.

Mine Level 4 Map: Abandoned Ruins, Unique Items.

Nie Fan was a little puzzled, the information published on the official website showed that the mine cave was only three floors, and he had never heard anyone say that there were four floors! Maybe the fourth floor is a hidden area for players to explore, but where is its entrance?

Maybe this map can find some answers, Nie Fan studied this map, but unfortunately it only has some broken fragments, and some paths can be vaguely seen, as if it is going down the waterway.

Would you like to go down and have a look?

Nie Fan had a strong curiosity about the fourth floor of the mine, after all, it was a hidden area that had not been explored before, and there was no record even on the information given to him by his father. My father only recorded some of his experiences participating in the closed beta of Sword of Dictatorship, and some of them were developed by my father, but the area that my father walked in accounted for less than one percent of all maps of Sword of Dictatorship. There are some hidden areas that my father has never visited.

Nie Fan's heart is a little nervous, and if you go to the fourth floor, you may find something different! Anyone in the game who suddenly finds a place that no one knows about will want to see it.

He sent a message to Xue Yu and Lin Suyue.

"Xiaoyu, I'm going somewhere else, you guys continue to brush the zombie overseer."

"You're not going to keep farming zombie overseers?" Xue Yu asked in surprise, the income from brushing the zombie overseer is so good, and the upgrade speed is so fast, Nie Fan would actually give up here and go to other places, he was very puzzled.

"Hmm." Nie Fan responded.

"Alright then, if you need to message me again." Xue Yu said, Nie Fan may have other plans, maybe he can find a better monster farming point?

Nie Fan returned to Target Village and bought things such as acceleration potions, void potions, random teleportation scrolls, etc., and after thinking about it, the broken rune stone might be used on the fourth floor of the zombie mine, after all, it was also a task item that exploded from the zombie overseer, and he brought the rune stone with him, and ran towards the direction of the zombie mine.

According to the road originally discovered, Nie Fan went directly to the third layer of the zombie mine, followed the path depicted on the leather, and began to explore the next way.

It is two completely different paths from the river to the zombie overseer refresh area, swimming along the water flow all the way forward, the path drawn on the leather is blurry, I don't know how to go, looking ahead, the water is starting to surge, there are several rivers turning over there, which one should I take?

After pondering for a moment, Nie Fan suddenly had some thoughts, no matter which side of the river it took, if the zombie mine cave has a fourth layer, it must be deeper underground, of course, the water flow is from top to bottom, as long as you follow the water flow and don't go upstream, you should be able to find the fourth layer of the mine!

Nie Fan activated the transformation seal skill, dived underwater, and felt the flow of water swimming forward, he could clearly feel that the water was flowing far underground.

I don't know how long it will take, so in order to avoid not having enough time to transform into a seal, Nie Fan sped up his swimming speed.

There is a section of the river that is deep underground, and there is no end in sight going forward, if it goes down like this, and there is no way to reach the surface of the water after five minutes, then Nie Fan will have to hold his breath under the water and die. But in about a minute, he saw some golden light, and it seemed that he was about to go out.

There seemed to be something shining under the water, Nie Fan quickly stopped and swam down, the bottom of the water was covered with pebbles, and between the many pebbles, two pieces of something were emitting a faint white light.

Seeing their appearance clearly, Nie Fan was slightly stunned, this thing he was very familiar with, it was actually a broken rune stone!

Picked up the two broken runestones, plus the one in his backpack, a total of three, their shapes seemed to be slightly different, and the patterns on them were also inconsistent.

I don't know if I can put it together, Nie Fan thought, let's go ashore first, and continued to swim forward for a distance, and after seeing the bright light above, Nie Fan suddenly got out of the water.

The dazzling white light made Nie Fan quickly cover his eyes with his hands, it had been in the dark for too long, and these white lights made his eyes stinging a little, and at this moment, a system prompt sounded.

System: You have discovered the fourth floor of the Zombie Mine - Forsaken Ruins, and you have gained 20 Truth and 32,900 Experience.

After receiving this system message, Nie Fan saw that his experience points had skyrocketed, and he had risen directly to level 29, and under normal circumstances, he found that an ordinary map could only get 1 point of true knowledge, and it seemed that he found a hidden map, and there were some additional rewards, and he actually obtained 20 points of true knowledge, which made him a little surprised.

After checking the surrounding environment, this is a deep mine, I don't know how far from the ground, the walls around the mine are covered with white stones, they emit a faint white light, which is the material for making rune stones!

However, these white stones were inlaid on the rock wall, and it was impossible for Nie Fan to pick them off by hand, so it was estimated that he would have to find miners to mine.

The first layer of the zombie mine produces white copper, the second layer produces a small amount of bronze, and the third layer produces a small amount of black magic copper. I don't know what kind of ore they are, but I guess even if these stones are dug up, I don't know how to use them, can they be used to make rune stones? There doesn't seem to be a production class for making runestones in the game!

However, according to ancient legends, these stones are supposed to be useful and precious.

Let's dig them again when we know how these stones are used, Nie Fan thought.

~~ Yesterday I only received seven thousand recommendations.,It seems that the goal is set too high.,Today's goal is eight thousand.,When you reach eight thousand snails, you will add a more chapter ^_^.
