This special corpse demon is an iron-smelting corpse demon that is one grade higher than the ordinary corpse demon, in addition to the characteristics of ordinary corpse demons such as infinite strength, tenacious vitality, and not afraid of pain, there is also a layer of sharp carapace like a hundred refined iron growing in various places on its body.

These high, raised and extremely sharp carapaces not only cover the location of the weak points in the whole body, but also the defensive energy is extremely strong, and even the medium-grade spirit weapon cannot be cut and broken.

Zhang Mu stood in the cave and observed for a while, and after weighing it in his heart, he began to silently mobilize the aura in the dantian, the ever-changing Ganges Jinsha Array Base.

Two days ago, he had just broken through to the realm of foundation building with the "Ming Dao Sutra" based on the two peerless scriptures of the "Sun Sutra" and the "Taiyin Sutra", and he could just use the more than 100 corpse demons in this cave to test the results of his cultivation and see what level his strength had reached in the foundation building realm.

Zhang Mu made a decision, his dark eyes immediately became bright and sharp, and a whirlwind of spiritual qi also stirred up around his body, blowing the gravel at his feet to fly upside down in a circle, hitting the stone wall in the cave, making a crisp sound.

This movement immediately attracted the attention of more than a hundred corpse demons, and the bloodshot eyes on the hideous face looked here, and when they saw someone appearing, they were all agitated.

However, due to the suppression of the iron-smelting corpse demon, he did not immediately rush towards Zhang Mu, but hooked his claws and bent his back, making a look of being ready to go.

After the iron-smelting corpse demon noticed the abnormality, it slowly turned its head to Zhang Mu with a creaking sound on its neck that seemed to be a dilapidated door panel turning.

His bloodshot eyes stared at Zhang Mu gloomily, and said in a hoarse voice.

"Who are you?"

Zhang Mu looked at this iron-smelting corpse demon and said grimly.

"The one who wants your life!"

Before the words fell, the figure had already rushed towards the corpse demons and took the lead in launching a thunder attack.

Seeing this, the iron-smelting corpse demon showed a sneer on its hideous face, and then let out a piercing scream.

After more than ten corpse demons heard the strange scream, they immediately rushed towards Zhang Mu with a low and muffled roar like a pack of wolves predatoring.

Since it is to test one's own extreme, it is natural that there can be no reservations.

Zhang Mu kept at his feet, waiting to get close to him, and pointed like a sword, his fingertips were full of light, directly hitting the weakness of the corpse demon.

The movements were clean and fast, just a look, and the corpse demon in front of him was instantly lifeless, and stood straight in place.

After the strong wind brought out by Zhang Mu blew, it began to fall slowly.

The bloodshot eyes of the Iron Refining Corpse Demon instantly tightened, and it clearly distinguished that Zhang Mu was only in the early stage of foundation building through the qi machine, but the strength he showed was not at all like that of a monk in the early stage of foundation building, and it was a few points stronger than the peak of foundation building.

Moreover, as an iron-smelting corpse demon, of course, it knows the weaknesses of ordinary corpse demons, but like Zhang Mu, not only can it find these fleeting weaknesses in an instant, but it can also complete the killing through these weaknesses in an instant.

He didn't dare to hold it up, and let out a strange scream again, causing all the remaining nearly 100 corpse demons to pounce on Zhang Mu.

At the same time, it itself also stood up blatantly, exuding a terrifying momentum, and also rushed towards Zhang Mu.

Zhang Mu saw that the corpse demons wanted to surround him, so he deliberately slowed down a few points, so that the corpse demons formed a situation of encircling him.

On the one hand, this move is to test the cultivation extreme, and on the other hand, it is also to kill all these corpse demons once and for all, and then go to the troublesome side after they escape.

Zhang Mu's fingertips shone brightly, stepping on the eight desolate steps, his body was like a dragon, shuttling between the corpse demons.

Everywhere they passed, the corpse demons trembled all over, all of them were cut off from all life in an instant, and they slowly fell to the ground.

This scene is really ten times more ferocious than a tiger entering a flock!

Of course, the corpse demon is a lamb to be slaughtered, and Zhang Mu is a tiger descending from the mountain!

Seeing that it was only a few breaths, there were only thirty or forty of the more than 100 corpse demons left, and before they had time to meet Zhang Muzhao, they had already retreated in their hearts.

While directing the remaining corpse demons to pounce on Zhang Mu, he began to quietly touch towards the entrance of the cave.

Zhang Mu was paying attention to the Iron Smelting Corpse Demon's every move from beginning to end, and when he saw that the Iron Smelting Corpse Demon wanted to escape, he immediately escaped from the siege of the Corpse Demon and stopped in front of the Iron Smelting Corpse Demon.

At this time, the iron-refining corpse demon was already shocked by Zhang Mu's superior fighting ability and did not dare to make a move, and his bloodshot eyes flashed, thinking that Zhang Mu knew so much about the weakness of the corpse demon, he immediately said in a hoarse and heart-scratching voice.

"Looking at your method of dealing with corpse demons, were you once also a member of the Bloodthirsty Demon Palace?"

When Zhang Mu heard the inquiry of the Iron Smelting Corpse Demon, his heart moved, and he didn't make a move for the time being, but showed an interested look and said.

"Yes and what, and what is not?"

Zhang Mu pretended to look like this, in fact, he wanted to see if he could extract some information from the mouth of the iron-smelting corpse demon, to see why they were gathering here, and why they frequently attacked the spirit stone mine caves in Beishan Town.

Seeing that Zhang Mu had stopped, the iron-smelting corpse demon relaxed his hideous face slightly, but he still said very hardly.

"If not, if you kill so many corpse demons from me, you and I will naturally be endless!"

"If so, in the case of the same door, I will be merciful to let you go, let's go to the sky, and today's matter will be revealed!"

Zhang Mu smiled when he heard this, feeling that the iron-refining corpse demon in front of him was slightly different from the one he had seen in the Bloodthirsty Demon Palace.

Those are all blood-drinking, extremely ferocious, not as sleek as the head in front of them, to put it simply, there is no brain in front of them.

"There aren't many iron-smelting corpse demons who are as cunning and active as you."

When the Iron Smelting Corpse Demon heard Zhang Mu's words, he was taken aback, thinking that Zhang Mu wanted to continue to do it, and hurriedly asked, "What do you mean by this?" ”

"What do you mean?" Zhang Mu stared at the iron-smelting corpse demon with sharp eyes, and said, "I mean you still have a little brain. ”

After a pause, he continued.

"I'll ask you a few questions, and if you answer truthfully, I don't mind letting you go!"

"What's the problem?" The Iron Refining Corpse Demon said.

"First, why are you gathered here?" Zhang Mu said, looked at the remaining thirty or forty corpse demons, and said, "Although I don't know much about corpse demons, I also know that this place is not suitable for keeping so many corpse demons in captivity. ”

Zhang Mu's later sentence was to knock the iron-smelting corpse demon and ask the iron-smelting corpse demon not to fool him with lies.

When the Iron Smelting Corpse Demon heard this, his bloodshot eyes narrowed slightly, knowing that he couldn't fool Zhang Mu, so he said truthfully.

"I was ordered to hide here with these corpses."

"Whose command?" Zhang Mu asked.

"Turning into a silver corpse." The Iron Refining Corpse Demon said.

The grade above the iron-smelting corpse demon is the red bronze corpse demon, and the strength generally corresponds to the monk's realm of gathering spirits, and the higher up is the silver corpse demon, and the strength has also increased to the realm of condensation.

Zhang Mu didn't expect that there was a silver corpse demon with condensation strength behind this, so he hid the surprise in his heart, and continued to ask calmly.

"Second question, why did you attack the Lingshi Mine in Beishan Town and kill so many innocent miners?"

"This is also fate, I don't know the specific reason." The Iron Refining Corpse Demon said.

"You really don't know why?" Zhang Mu didn't believe that the Iron Smelting Corpse Demon didn't know anything, his hand lit up with a dazzling spiritual light, and he asked sharply: "I don't have the patience to accompany you to spend it!" ”

Seeing this, the iron-smelting corpse demon showed a hesitant look on his hideous face, and he was silent for a moment before he spoke out.

"The reason I know is to obstruct the mining of this spirit stone mine in Beishan Town, so that they can reduce the production of spirit stones."

Zhang Mu couldn't help but be a little strange when he heard this reason, hiding such a corpse demon here was just to reduce the output of the spirit stone mine in Beishan Town?

After thinking about it for a while, he suddenly remembered the task entrusted to him by Mi Muyun, the content of which was to check whether the county magistrate of Heishi County was suspected of embezzling the spirit stone handed over.

Reduced production? Embezzle spirit stones?

These two words coiled in Zhang Mu's thoughts, making Zhang Mu feel that there seemed to be some kind of connection between them, and then asked.

"Except for here in Beishan Town, are there any corpse demon attacks in the spirit stone mine caves in other places?"

"I don't know about the rest of the place, I'm just in charge of the town of Beishan." The Iron Refining Corpse Demon said.

"Last question, where is the silver corpse demon?" Zhang Mu asked.

When the Iron Refining Corpse Demon heard Zhang Mu asking about the information of the Silver Corpse Demon, a trace of fear appeared on its hideous face, but now that it knew that it was invincible to Zhang Mu, it still said truthfully: "That one is in the realm of Lingya Mansion, I don't know where it is." ”

Zhang Mu has been staring at the iron-smelting corpse demon, looking at its expression, he should really not know.

At the same time, I felt that I was almost the right to ask, and if I continued to ask, I might not be able to ask any useful information, so I said.

"Alright, you're leaving."

"You really let me?" The Iron Smelting Corpse Demon couldn't believe that Zhang Mu would let it go so easily.

Zhang Mu snorted and said, "What? I don't want to go yet! ”

"Let's go, I'll go right away." After the iron-smelting corpse demon finished speaking, he let out a strange scream and walked towards the outside of the cave with the remaining thirty or forty corpse demons.

Zhang Mu looked at the empty back of the iron-smelting corpse demon, and the corners of his mouth raised slightly, and said.

"I thought it would have more brains than other iron-smelting corpse demons in the demon cave, but I didn't expect it to be the same thing!"

When the iron-refining corpse demon heard this, his heart was cold, and the idea of speeding up to escape from here was just about to float, and he suddenly felt his whole body tremble slightly, and then he saw Zhang Mu's figure flashing from among the thirty or forty corpse demons.

Then, like many corpse demons, it was completely lifeless in an instant, and began to slowly fall to the ground, looking at Zhang Mu when it was dying, and said with difficulty in its throat: "For..."

Before he finished speaking, he had completely collapsed.

Zhang Mu took out dozens of fire talismans from the storage jade ring, and at the same time flew towards the cave, igniting the corpse demon corpses all over the ground, and then said lightly in the direction of the iron smelting corpse demon.

"Back killing iron smelting at the snap of my fingers, looking for flaws in the two ribs of red copper, rumors are honest and do not deceive me."

"I just don't know if the flaws of the red bronze corpse demon are really between the two ribs, I must give it a try if I have a chance!"

When Zhang Mu was trapped in the Bloodthirsty Demon Palace, he accidentally obtained an unknown book in the Tibetan Scripture Building, and these two sentences were recorded in that volume.

Back then, Zhang Mu also relied on the body refining exercises in this anonymous book to successfully lay a solid foundation for entering the Tao with martial arts!
