Auf stood in place waiting for Ruan Chi, and he didn't know how long it had been, but there was a violent vibration on the ground, followed by a very large green mushroom cloud rising from the sky.

The entire sky was dyed green, and just as Auf was shocked, a huge shockwave blew in.

Although he was mentally prepared from the beginning, Auf did not expect it to be exaggerated to such an extent, and he had no time to defend at all, and the person was blown away by the sudden air current.

Finally crawling out of the thick sand, Auve looked ahead in amazement, only to see that a few kilometers away from his current position, all of them had turned into a piece of scorched earth, and the original desert seemed to have been scalded by the flames of high temperature, turning into crystals.

Not only that, due to the excessive momentum of the explosion, there were obviously many places in this subspace that were cracked, and Auf looked up at the sky, and clearly saw where several gray spatial cracks were horizontal, and he felt as if he had been torn apart.

"The realm of a god-level powerhouse is really powerful, this kind of Cheng dù's attack can actually be performed twice a day." Auf was amazed, and once again felt terrified and admired by Ruan Chi's strength.

In fact, even a god-level powerhouse would not be able to use two forbidden spell-level attacks in a short period of time, because it would easily cause backlash. In this world, probably only a freak like Ruan Chi can do it.

Auf stood in place and waited for a moment, and a figure flew in the distance, who else would it be if it wasn't Ruan Chi.

Ruan Chi is in a very good mood now, not only has he successfully brushed 500 angry Ah Feng, but he has also gained a lot of experience points.

Originally, he had just been upgraded to level 99 and returned to 0 experience bar. Now it's up to 40% again. It's faster than riding a rocket. If it weren't for the Despair Explosion, the cooldown time of this skill would have been 72 hours. Ruan Chi really wants to stay here all the time to brush up on experience.

"Big brother, you're too powerful." Seeing Ruan Chi come back, Aufu looked at Ruan Chi with admiration.

System: NPC Of's opinion of you has increased by 15 points, and is currently respected.

Ruan Chi was stunned for a moment, a little puzzled why Aofu's favorability value had inexplicably improved, seeing his eyes full of "basic feelings", Ruan Chi just felt goosebumps.

"By the way, when I came back just now, I found the boss room on the third floor. Come with me. Ruan Chi hurriedly changed the topic.

More than an hour later, the two arrived at the final level of the third floor of the dungeon, located under a stone gate under a low hill deep in the desert.

The structure of the stone gate is the same as that of the first two floors of the underground palace, and after Ruan Chi handed over 500 angry hearts, the stone gate automatically opened, and a huge mine cave appeared in front of the two of them.

Ruan Chi and Auf walked in and found that this was really a mine, and in addition to some traces of excavation, there were some railroad tracks and tools for mining ore on the ground.

"Why are there caves here?" Auf muttered with a confused expression.

"Leave that alone, the boss is in there. Let's take out the boss. Ruan Chi looked at the system map, which showed that there was a big red dot in the depths of this mine.

The two then walked along the railroad tracks beneath the mine. After a while, I found the boss inside, and as expected, the boss is an enhanced version of an angry Ah Feng, whose name is Angry Ah Feng, level 96, health 230,000, and is also immune to physical damage.

This time, Ruan Chi didn't have a desperate self-explosion to use, so he could only slowly cut this boss, and after half an hour of "fighting", he finally grinded this boss to death.

"This is definitely Lao Tzu's most tiring battle, even more tiring than going head-to-head with the heavenly wheel and the nine ghosts." Ruan Chi wiped his sweat and then opened the system backpack to count the loot.

Anyway, it is also a level 96 boss, this angry Ah Feng snatched it than the stone spirit beast on the first layer, and even broke out two pieces of golden supreme quality equipment, and the most important thing is that it is knight equipment, and Ruan Chi can use it.

Tyrant's Leg Armor (Gold): Quality Supreme, Physical Defense 197, Magic Resistance 154, Strength +40, Constitution +35, Critical Hit +2%, Requires Professional Knight, Warrior. Requires level 95

Asura Heart (Gold): Supreme Quality, Max HP +20%, Physical Defense +130, Magic Resistance +130, Constitution +40, Intelligence +30, Requires Class None, Requires Level 96

One is leg armor and the other is jewelry, Ruan Chi took stock of the original equipment on his body, removed some outdated equipment, and replaced it with a new one.

Now, more than half of the equipment on Ruan Chi's body is of golden supreme quality, and he feels that he is already worthy of his current level.

In addition to the equipment, the BOSS also exploded a skill book, and it was also a magic skill, Ruan Chi didn't care much at first, after all, he had no reason to learn magic skills as a physics profession, not to mention that the professional requirements for magic skills were either magicians or elemental mages, and Ruan Chi couldn't learn them if he wanted to.

However, to Ruan Chi's surprise, this magic skill book turned out to be a general skill, and this was the first time he had encountered it. What's even more rare is that Ruan Chi found that he was actually qualified enough to study.

Skill Book (Thunder Spear): After using it, the player will automatically acquire the skill Thunder Spear, which will inject the power of thunder and lightning into both hands, inflicting 420% lightning magic on the target, and a 100% chance to paralyze the target for 5 seconds. Requires level 80, requires no profession, requires no pre-skills, requires attribute configuration spirit 150 points, and intelligence 267 points.

Ruan Chi definitely couldn't learn this skill before, but since he got the three fragments of the Apocalypse, the improvement of his full attributes alone has exceeded 300 points on average, and the mental and intellectual attributes are properly enough.

After learning this skill, Ruan Chi and Aufu walked around the cave and soon found the entrance behind the boss.

System: You have found the fourth floor of the dungeon.

"Finally on the fourth floor!" Ruan Chi stretched, pulled out the system menu and looked at the time, showing that it was 20:43 in the evening.

Ao Fu also realized that he had entered this dungeon with Ruan Chi for a long time, and said a little worriedly: "Big brother, there is still one day before the treasure hunt ends. Shouldn't we go back now? ”

Ruan Chi touched his chin and said, "Time is a little short. So be it. After a while, we will find a safe place to have dinner and take a nap, and then we will brush the last fifth layer and go back immediately. ”

The corners of Auf's mouth twitched, and he said, "Big brother, I didn't mean this ......"

Ruan Chi was about to speak, but suddenly stopped and looked in a certain direction.

Offchi said: "Big brother, are you okay?" ”

Ruan Chi said in a low voice: "There seems to be footsteps." You hear me? ”

Auf was stunned for a moment, then pricked up his ears, and sure enough, there was a sound of footsteps coming from in front of him, and in addition to the sound of footsteps, there was also a sound that seemed to be made when dragging a heavy object.

Ruan Chi muttered to himself, "Could it be the guard of the fourth layer?" ”

The terrain on the fourth level felt like a huge underground cavern, and at the foot of the two of them now stood there was a rusty railroad track.

"Bell, bell, bell......"

The footsteps grew louder and louder, interspersed with the sound of the heavy object crashing against the rails. As the sound approached, a large shadow gradually appeared in front of it.

"Squeak!"

The shadow stood in front of Ruan Chi and Auf and shouted twice. He took a step forward, completely exposed to them, and surprisingly, the true face of the shadow turned out to be a giant gopher.

But this gopher looks a little funny, or a little cute......

Covered in light gray fur, he wore an engineering helmet on his head, a pickaxe on his shoulder, a towel around his neck, and a bucket truck with pieces of ore on it.

Ruan Chi was shocked by the gopher-like creature in front of him, and he raised his forehead for a long time and said, "This guy shouldn't be the guard of the fourth layer, right?" I feel that the painting style is a little different from the first three layers. ”

However, at this time, Auf suddenly lost his voice and said, "The dark rat clan? Why are they in this place? ”

"Dark rats?" Ruan Chi was stunned for a moment, looked up at the top of the gopher's head, and sure enough, there was a name on it, but it was not called the dark rat clan, but called Mimidi.

Huh? Monsters still have names?

With a hint of doubt, Ruan Chi immediately threw a reconnaissance technique at the head of the gopher in front of him.

Mimidi: Level 41, HP: 4500/4500, MP: 0/0

Physical Attack: 534, Physical Defense: 257

Magic Attack: 0, Magic Resistance: 0

Hit: 190, Evasion: 125

Profession: Engineer

Sex: Male

Age: 9 years old

Faction: Neutral

Country of Birth: Enchanted Isle

Note: The sub-human race living in the territory of the dwarves at the southern end of the Miracle Continent has low intelligence, and is often hired by the dwarves to dig underground ores because they are good at digging holes.

Ruan Chi also noticed at this time that the name of this gopher was still neutral yellow, that is, it was not a monster, but an NPC.

Auf was also shocked at this time, and muttered: "The Dark Rat Clan has always been a vassal race of the Dwarf Race, and it stands to reason that they can't appear here?" What's going on? ”

Ruan Chi asked, "Is there still a Dark Rat clan in the Miracle Continent?" Aren't there only nine races? ”

Ruan Chi has lived in this world for almost a year and a half, and he still has some understanding of the racial forces of the Miracle Continent, the so-called nine races, strictly speaking, refers to the human race, orc race, dwarf race, elf race of the neutral camp, elf race, Tianyu clan, mermaid clan, as well as the dragon clan, sea monster clan and blood elf clan of the chaotic camp.

As for the hidden races such as the Titans, because they rarely appear, they are not classified as the tenth race.

So what's going on with the dark rat clan in front of you.

Auf explained: "The dark rat race is actually a subhuman race, because of its limited intelligence, it is not a regular intelligent race, and can only be regarded as a vassal race of the dwarf race......

Because Auf was too shocked, he didn't notice why Ruan Chi, a "senior master" who had lived for 500 years, didn't even understand this kind of common sense.

After listening to Auf's explanation, coupled with the information obtained from the reconnaissance technique, Ruan Chi almost understood, it turned out that in addition to the nine major races, there were many subhuman creatures on the Miracle Continent.

Like the dark rat clan in front of him, as well as the goblin clan living in the orc realm, and the harpy clan in the elven realm are all subhuman races.

Their intelligence is lower than that of normal intelligent races, but it is higher than most of the magical beasts, so they are called subhuman races, because the number of subhuman races is not large, and there is no complete social system, so under normal circumstances, subhuman races like the dark rat race will generally be attached to any of the nine major races.

The Dark Rat are vassals of the Dwarves, and under normal circumstances, they will only live in the mines developed by the Dwarves all year round, and will not take a step out of the mines all year round.

Therefore, it is no wonder that Auf showed such a surprised look when he saw the dark rat in front of him, after all, this magic island, but on the vast sea thousands of kilometers away from the Miracle Continent, not to mention that it is impossible for a subhuman race like the dark rat to cross the ocean to come here, even if it is a dwarf race, it takes a lot of effort to run to such a far place.

When Ruan Chi and Ao Fu were looking at the dark rat in front of them, this dark rat named Mimidi was also tilting his head to look at the two intruders in front of him.

Surprisingly, Mimidi didn't attack, instead, its two red eyes looked at Ruan Chi and Aufu for a moment, then suddenly squeaked twice, then stretched out a hand, pointed in a certain direction behind him, and then pointed at himself.

"Huh? It told us to go along? Ruan Chi said.

"Big brother, it's too strange for this dark rat to appear here, let's not go with it." Auve persuaded.

"It's okay, this guy has no ill will." Ruan Chi smiled, it didn't matter.

The reason why Ruan Chi is so sure is naturally because of the color of the name on the head of this dark mouse called Mimidi, since the system marks its name as yellow neutral, then there should be no problem.

Ruan Chi insisted on following the dark rat, although Auf felt that it was wrong, but after thinking about it, he agreed, but he did not let his guard down, but drew his weapon and followed with a vigilant face.

The two of them walked along the underground railroad track to the depths of this underground mine, and along the way, Ruan Chi looked relaxed, looked around, and looked at the environment of this mine.

There are obviously many traces of artificial excavation in the mine, and some of the traces are still new, and it seems that the dark rat in front of him has really lived here for a long time.

Ruan Chi's gaze then fell on the bucket truck dragged by Mimidi, where there was a pile of black ore, and it seemed that it was no longer able to tell what kind of ore it was.

The road in the mine is very complicated, and along the way, Auf is also worried that the fourth floor of this dungeon will run out of guards such as stone spirits and fire monsters.

But more than an hour passed, not to mention the guards, not even a single mouse appeared. After another half an hour, the road ahead suddenly became clear.

What is surprising is that this dark rat named Mimidi actually took the two of them to a huge crypt, and what is even more shocking is that a small town has been built under the crypt. (To be continued......)
