Rex and the others, who entered the dungeon, went straight to the place where the incident occurred, that is, outside the dragon's lair.

"I heard that a dragon appeared here not long ago?" Rex asked.

The attendant on the side immediately stepped forward and nodded in response: "Yes, Your Highness, at that time, thousands of adventurers came to crusade against the dragon, but all of them were defeated, and the casualties were quite heavy, and most of them became the dragon's dung. ”

"It's a dragon." Rex couldn't help but sigh, "If I can get a dragon with me, what will my brothers do." ”

The corners of the attendant's eyes twitched, and the people who followed Rex showed expressions of wanting to eat peaches.

"This human, if you just want to sigh about life here, please get out of the way." Lan Lan's voice came from behind.

The attendant hurriedly explained: "Your Highness, the elven clan has a special prop to detect the fluctuation of undead magic, let them come." ”

"Okay, a few troubles." Although he was not welcomed, Rex still showed proper manners.

Ignoring him, she crouched down in front of the already stinking dwarven corpse and pulled out a clear crystal.

In just a few seconds, the crystal turned black.

"The undead indeed!" Lan Lan's narrow eyes narrowed slightly.

Everyone suddenly felt bad, and at the same time secretly rejoiced that there were enough people brought today.

"The order is given, everyone uses the team as a benchmark, and looks for the traces of the undead clan separately, and after finding it, immediately notify the large army." Rex also had a solemn face, but he was more eager to try it than others.

If he can catch the undead here, it will definitely be a great achievement, enough to affect His Majesty's evaluation of him.

Soon, orders were passed out layer by layer, and people from all walks of life launched a carpet search in the form of squads.

And Rex and the others are following behind the elves, there is no way, who makes the family have tracking technology.

The group walked along Lu Qi's escape route yesterday and came to the entrance of the monster base camp...... One!

Here, they found the skeletons of three dwarves scattered on the ground.

"It looks like the other side abandoned these skeleton soldiers." Rex said a word of nonsense......

The attendant on the side hurriedly stepped forward and proposed: "Your Highness, since the undead clan abandoned the skeleton soldier here, it means that he should have been here, and there will definitely be traces nearby." ”

"Yes, the order will go down and intensify the search of this area." Rex immediately ordered.

"By the way, Your Highness, it's best to find someone to watch the passage to the second floor to ensure that during the search, there are no people entering and leaving between the first basement and the second basement floor." The squire continued to propose.

Rex nodded again and again, and gave another order.

At this scene, Qi Lan on the side sneered, thinking that he was a character who dared to eradicate evil, but he didn't expect that he was a waste prince who had no opinions.

Because it was a dead end, the crowd began to turn back. And at the moment of leaving this dead end, the group of elves found that the tracking magic had failed, and in desperation, they could only follow the others and search aimlessly.

……

On a certain road in the basement level, two mercenary squads carefully searched for the whereabouts of the undead.

At this moment, one of the people in the team with a more sensitive nose smelled a strange smell in the air.

"Do you smell anything?" The man paused and sniffed carefully: "Something seems to be burned." ”

"The smell of torches, right?" The teammate next to him smiled.

"Absolutely not, the torch is stained with fire oil, and it smells of tar, which is different from this smell." The man shook his head and retorted.

As he spoke, the taste became a little stronger.

"I smell it too, it looks like someone is burning firewood!" Another person in the line shouted.

"Yes, yes, it's the smell of firewood!"

"Wait, could it be that the undead are camping in front of it and making a fire?"

"Possibly!"

"Wait a minute, aren't the undead all skeletons? What do you do with a fire? Roasted bones? ”

"Who told you the undead are skeletons? People are also flesh and blood, and they need to eat and drink Lazar...... Go back and read more books by yourself, quick, come to someone, and report the situation here! The credit for discovering the undead is ours! ”

"Okay."

One of the sharpest men in the group carried a torch and passed the word to the rear.

But soon the messenger found out that he was not the only one who was looking for His Royal Highness the Fourth Prince to report the news, and everyone smelled the burning smell.

Some of these messengers were just routine reports, while others, like their team, believed that the burnt smell was related to the undead.

As a result, the smell of burnt fire naturally became unremarkable, and the messengers who thought they had found the undead returned disappointed, inhaling the smell of burning, and continued to search for the whereabouts of the undead.

Gradually, some people began to feel dizzy, and people with weak constitutions even fell to the ground in a coma!

"What's going on?"

Everyone finally sensed that something was wrong.

And not only their teammates, but even they themselves began to feel dizzy.

Suddenly, in the darkness at the end of each passage, a beating flame appeared, and only skeletons with a clump of burning weeds tied to their feet approached them.

"Undead?"

"No, it's just a one-layer skeleton monster!"

Although the skeleton monsters and the skeleton soldiers summoned by the undead clan are both bone bodies, there is a clear difference.

To put it simply, the skeleton monsters are all printed from a template, and the skeleton soldiers look strange because of the different origins (corpses).

Those with less bright brains couldn't understand why there was a burning weed tied behind these skeleton monsters? Haven't you come to the basement to explore for so many years, and a new variety of monsters has appeared here?

Of course, there are also many alert people who are aware of the danger!

"No, Your Highness, we've been tricked!"

The quickest to react was the squire beside Rex, who said anxiously: "Oh no, Your Highness, they want to lower the air here by burning weeds, raise smoke, and suffocate us to death!" They also lit jatropha and wanted to stun us! ”

"What do you mean? Can the air still be used up? And who are 'they'? Rex felt like he was in a blind spot.

The attendant was so anxious that he almost spit out a mouthful of old blood, common sense, Your Highness! This is common sense! And 'they', of course, refer to the enemy!

However, Rex doesn't understand, it doesn't mean that others don't understand, especially Qi Lan, as a wind whisperer, that is, a learner and user of wind magic, her face changed greatly after a little inspection.

"I've been tricked, retreat!"

Without saying a word, Qi Lan activated the wind magic to isolate the smoke, and ran towards the exit with the people of the elf clan.

Rex still hadn't figured out why, but he was right.

At the same time, more and more burning skeletons appeared, their feet and bodies tied to the burning weeds and wet and dry.

For a while, the entire underground floor was filled with smoke, countless people inhaled smoke and dust, and the entire lungs burned like fire. And the more the body wants fresh air, the more it will inhale a lot of smoke, and the feeling of suffocation will further increase, and the vicious circle will be.

However, there are also people who are more intelligent and know how to cover their mouth and nose with a cloth dipped in water.

It's just that......

"Wait, I remember the exit is going this way, huh? Why is there no way? ”

"Ahem~ You're mistaken, it should be over there!"

"Damn, who the hell is it!"

"Ahem~ Captain, I can't do it, leave me alone, you guys go quickly!"

……

In this way, the humans who came to track down the undead clan, one by one, fell to the basement floor.

Rex, who fled with the elves, found that he had unknowingly lost the other party, and not only that, but the attendants around him were also falling one by one, and he could only barely rely on the purification magic on his armor to support himself.

Rex looked bitter, he knew he wouldn't come.

At this point, he had no choice but to go alone, but soon he discovered a rather difficult problem, and he was lost.

As a prince who has just come of age, he has never even been out of the royal capital a few times, let alone a dungeon, and he is not familiar with this place at all. I had a map in my hand, but I couldn't read it at all......

"This ......"

Rex panicked and began to run around the basement. The smoke, the heat, and the corpses all over the ground broke his heart little by little. Gradually, the purifying magic on the armor wore off its effect, and the pungent smoke rushed into the mouth and nose with the breath, and rushed to the lungs.

He began to cough, and the toxin of the jatropha made his brain dizzy and his limbs stiff.

With a pop, he fell to the ground.

"I ...... I'm going to die? ”

Rex's mind was in a state of confusion, and his parents, brother, sister, and fiancée flashed in front of him...... And so on.

At the end of the Phantom Land, he vaguely saw a short figure, approaching him.

……

"Oh, Lu Qi, this person seems to be a prince! Look at the little crown on his head. ”

"Hey~"

Lu Qi looked at the people on the ground and sighed, fire plan, fold life......

"Kill him, give him a relief, and you can also upgrade a few more levels." The little skeleton said.

"Okay." Lu Qi began to chant the incantation very simply, and then a sharp blade of air broke through the smoke and slashed at the prince's neck.

With a ding, the air blade was blocked by the protective magic remaining on the armor.

The scene is a little embarrassing......

"Oh, Lu Qi, I guess you can't split this layer of magic, it's a pity. It seems that he can only die in agony. The little skeleton sighed.

Lu Qi is also very helpless, sometimes, it is not a good thing to wear too thick.

The two monsters moved on.

One of them is a lime and the other is a skeleton monster, neither of them needs to breathe and is not afraid of poisoning, so the two monsters can walk in this extreme environment with impunity.

The flames continued to burn, and the smoke became more diffuse.

And Lu Qi's level is rising steadily.

Level 10 ...... Level 13 ...... Level 15 ......

Wind spells. The proficiency of the blade is also increasing little by little, from the beginning when you can only hit one blade, to now, you can fire three blades at a time!

"Wait, go to that place!"

When leveling up, Lu Qi made some unexpected discoveries, and worked hard to gather the liquid in his body in one direction, so that his round body could support a small protrusion and point out the direction for the little skeleton.

When he arrived at his destination, Lu Qi jumped off the shoulders of the little skeleton and landed on the corpse of a female elf. Her companions lay around the corpse, and it seemed that they didn't hold it either.

Of course, under normal circumstances, this group of elves must have the ability to escape, and it is not only them, about thirty percent of the human beings have hope of escaping. It's just that Lu Qi made a little fireworks and trapped them all here.

After some exploration, Lu Qi found a inheritance crystal!

With a snort, Lu Qi sucked the inheritance crystals into his body, and the scene in front of him changed slightly.

He saw a tall ancient elf, wand in hand, muttering a large number of complex and unfamiliar words in his mouth, and then a green light flashed in his eyes, and a seemingly soft breeze enveloped him.

With that, a cloud of flames shot towards the Ancient Elf, engulfing him, but the breeze around him easily blew away all the flames.

Wind spells. Mu Chunfeng!

A protective wind magic that works wonders on things like fire, smoke, and poison gas.

Lu Qi twisted and twisted, and began to chant incantations with a pop, and then a breeze surrounded his body, isolating him from the smoke around him.

"Was that the bloodline essence just now?" The little skeleton came over and asked, it couldn't see it, but that didn't stop it from guessing.

And the bloodline essence is another name for inheritance crystallization.

"Yes." Lu Qi replied casually, but he didn't say much, and the little skeleton naturally didn't ask much.

Then Lu Qi twisted his body and climbed onto the shoulders of the little skeleton again, and the two monsters continued to look for the unlucky humans who had not lost their breath, giving them a relief.

When the level was raised to level twenty, Lu Qi found that he could not go up any further.

"Looks like that's all it takes." The little skeleton said.

"What do you mean? Why can't I continue to upgrade? Lu Qi was very surprised, level twenty was also a little too low. You know, he has the bloodline of a hundred clans, and he shouldn't be only level 20!

"Oh, Lu Qi, don't panic. This is the rule of the underground layer, all the creatures born here, the maximum can only reach level 20, even the city lord is no exception, but the city master is ten levels more than us, and the upper limit is level 30. The little skeleton explained.

Lu Qi was stunned for a moment, and his heart was full of unwillingness, and he hurriedly asked:

"That'...... Can't change it? ”

The little skeleton patted Lu Qi and comforted: "Don't worry, there is a way!" I'll talk to you about it when I get back. ”

Hearing this, Lu Qi's heart was a little better, but it wasn't much better.

And since the level can't continue to rise, there is naturally no reason for the two monsters to continue to wander here. So the two monsters turned back to the base camp from another passage and went to the snail city lord's room to check the harvest.
