I picked up skill fragments in the demon world

Chapter 81: Crystal Core Mutation

"Lei, Fox Spirit, go and do some work!"

"As for the benefits, Zhang Chen, you can just take them!"

Because Zhang Chen's gunpowder explosion not only sent rocks flying outside, but also sent some rocks flying into the stone chamber, fortunately without causing too much damage.

"What is that thing of yours? It acts up without any warning. Even a Twelfth Realm existence, without a natural warning sign or a unique escape skill, would probably be caught!" The Fox Spirit was now standing in the stone chamber, looking at the wreckage after the explosion, her eyes full of horror. She suddenly felt that it wasn't unfair that her physical body had been blown to dust back then.

Looking at the Fox Spirit's stunned appearance, her cherry-like mouth unable to close, Zhang Chen's heart suddenly stirred. He remembered the various unpleasant smells when he was making gunpowder, and the corners of his mouth slightly curled up: "Want to learn?"

He seemed like a wolf in sheep's clothing, looking at a little lamb with a smile.

This was free manual labor! With the Fox Spirit helping him make gunpowder, how much time could he save?

As for the gunpowder technology being leaked? Now the Fox Spirit was his skill, and his Soul-Hooking Chains were still linked to the Fox Spirit. Where would she have the opportunity to leak it? As long as he kept a close eye on her, the Fox Spirit would have no chance to betray him.

"Can I learn? Are you willing to teach me?" The Fox Spirit was stunned when she heard this, her eyes full of disbelief, filled with joy.

Even the Fox Spirit was drooling over such methods!

It acted up without any warning, making it impossible for people to resist. Even if an old Twelfth Order monster encountered it without preparation, they would be doomed!

"Learning this stuff is very hard, are you sure you want to learn?" Zhang Chen asked again to confirm.

The Fox Spirit nodded vigorously when she heard this. Of course, she wanted to learn! If she learned this method, she would probably be able to stand up and take revenge on one of her mortal enemies.

Zhang Chen smiled when he heard this, revealing two rows of white teeth: "I'll teach you when we get back!"

"But now I need you to move the rubble out," Zhang Chen pointed to the countless rocks on the ground.

Looking at the rubble scattered all over the ground, the Fox Spirit's small face suddenly collapsed, but she had no way to disobey Zhang Chen's order and could only pick up the rubble and throw it into the underground river outside.

"I said, instead of thinking about escaping, you're wasting time here. If we look for an escape route earlier, maybe there's still a chance of survival. If you continue to delay, we won't have much time left," the Fox Spirit said, turning her head to look at Zhang Chen while carrying the rubble.

Zhang Chen looked at the delicate and graceful Fox Spirit in white, constantly carrying large rocks, and suddenly felt a sense of contrast like Lin Daiyu uprooting a willow tree.

But after the Fox Spirit carried the rocks for a while, looking at Zhang Chen standing aside leisurely watching, she suddenly became unhappy: "I said... can't you help me with something? Look at how little strength I have, how thin my arms are. Isn't it hard to carry them back and forth? Can't you have a little chivalry?"

"You are my skill now! Have you ever seen anyone cherish their own skill? And you are in my skill state now, shouldn't you not know fatigue?" Zhang Chen unhesitatingly countered the Fox Spirit's words.

The Fox Spirit stopped talking, but started to mutter and complain about Zhang Chen, constantly murmuring something while carrying the stones.

Looking at the Fox Spirit swallowing her anger, especially as she carried the large stones panting, Zhang Chen felt extremely good.

The Fox Spirit did not know fatigue. In just the time it takes to burn an incense stick, the stone chamber was cleaned up. Then, Zhang Chen held the night-luminescent pearl and came to one side of the wall. He did not go to see the human race's illustrations. He wanted to see the demon race's illustrations so that he could learn from them.

The orange aura he had seen outside before was emitted from the patterns on the stone wall.

The stone chamber was very empty, and the height should be twenty meters. The light of the night-luminescent pearl could barely illuminate the stone chamber, but it was not difficult for Zhang Chen. He directly controlled the Fox Spirit to float in the air, hovering back and forth on the stone wall, using the light of the night-luminescent pearl to illuminate the stone wall.

"It's actually a mural," Zhang Chen said in surprise.

"This mural is a visualization secret method obtained by my Qingqiu clan. My Qingqiu clan's ability to touch the mysterious inner spiritual refinement method also comes from this illustration. As long as you visualize this illustration and obtain its true meaning, you can enter a mysterious spiritual induction realm and use that realm to temper your soul, thereby expanding your soul to the point where it can leave the body. It's just that this illustration is too dangerous and only suitable for my demon race to visualize. You shouldn't visualize it. If you become mentally disordered and your soul flies away, don't implicate me," the Fox Spirit floated in the air, using the night-luminescent pearl to illuminate the illustration.

Zhang Chen carefully looked at the lines on the stone wall, which were half a foot deep into the stone wall. The lines were soft and perfect, without any pauses. They looked as if they had been engraved on the stone wall in one go.

"The power of the ancient gods is truly incredible," Zhang Chen secretly said, looking at the depth of the marks. He saw that the lines were not damaged at all, as if, to the owner who outlined the lines, the bluestone in front of him was like flowing water, without any obstacles.

"Only if the other party's palm is sharp enough can it cut through the stone wall as if cutting through flowing water, without causing any damage," Zhang Chen said to himself.

At this time, Zhang Chen's eyes were looking at the lines on the stone wall, but unfortunately, the light of the night-luminescent pearl was too dim, and it was impossible to completely illuminate the pattern on the stone wall at once. Zhang Chen could only see the scattered lines on the stone wall, but he couldn't see the whole picture of the lines at all, and he couldn't tell what was carved on the wall.

"Is there anything brighter?" Zhang Chen looked at the Fox Spirit Nannan, who was holding the night-luminescent pearl as a light bulb.

"There are some torches," Fox Spirit Nannan said.

"Go and get them quickly!"

Zhang Chen hurriedly urged.

How could the brightness of the night-luminescent pearl compare to a torch?

There was no comparison at all!

Fox Spirit Nannan glared at Zhang Chen, reluctantly handed the night-luminescent pearl to Zhang Chen, and then turned into a puff of green smoke and disappeared into the stone chamber.

After the Fox Spirit left, Zhang Chen did not move around, but stood in front of the wall, carefully pondering the changes in the lines. Before he had waited long, he saw Fox Spirit Nannan holding seven or eight torches, and also holding a flint in her hand, coming to Zhang Chen's side:

"These torches are all specially made by my Qingqiu clan. One torch can illuminate for a day and a night," Fox Spirit Nannan said.

Zhang Chen took the torches, then signaled Fox Spirit Nannan to light the torches with the flint. Then, in the next moment, he saw a small sun rising in the stone chamber, like a 120-watt light bulb, making the entire stone chamber as bright as day.

"What are these torches made of?" Zhang Chen asked curiously.

"I don't know," Fox Spirit Nannan said irritably: "I'm not an omniscient person."

Zhang Chen ignored the Fox Spirit's impatience, but raised the torch and looked at the stone wall. Only then did he see the pattern on the entire stone wall clearly, and he couldn't help but be stunned: "That is... a fox with nine tails?"

"That's right! That is my fox clan's ancestor, a twelfth-order god!" The fox spirit's voice was full of pride: "My fox clan has a unique talent, the substitute death technique. As long as the bloodline returns to its ancestor and grows a tail, it can constantly substitute death. It's a pity that I suffered a great enemy a few years ago and wasted a tail. When I tried to seize a body, I encountered an accident and wasted another tail. Otherwise, how could I have been ambushed by you?"

Fox Fairy Nan Nan's voice was somewhat sorrowful. She, the dignified Fox Fairy Nan Nan, a seventh-order existence, actually capsized on a boorish man. How could that kind of resentment be described in a few words?

It was simply screwed!

The feeling was as if you were a Golden Core realm expert, but you were hacked to death by a mortal with random knives. Tell me, wouldn't you feel aggrieved?

She, Fox Fairy Nan Nan, was about to die of grievance!

If she had died, perhaps it would have been the end of it all, but now, an accident had happened, and she couldn't die!

Zhang Chen ignored the fox spirit. Instead, his eyes were fixed on the carving. After observing it for a long time, he didn't feel anything.

However, there were four large characters above the stone carving. The four characters were bold and powerful, with a kind of murderous aura. They looked full of killing intent, but he didn't recognize the characters.

"I still need to learn to read as soon as possible, so that I won't miss any opportunities in the future because I can't read," Zhang Chen thought to himself.

"What do those four characters say?" Zhang Chen asked.

"Celestial Fox Devouring the Moon," the fox spirit said.

"Celestial Fox Devouring the Moon?" Zhang Chen looked at the pattern. It was indeed a fox spirit with nine tails, stretching its neck and holding a ball in its mouth.

The most important thing was that the ball was engraved with thousands of strange symbols the size of rice grains, which looked very mysterious.

"What are those symbols?" Zhang Chen asked.

The fox spirit hesitated upon hearing this: "Those are the life-source characters of my fox clan, describing the true meaning of the moon. Only by visualizing those symbols can you draw in the essence of the moon. You must not try it. You don't have the fox clan's bloodline, and there will definitely be big trouble."

Zhang Chen remained noncommittal upon hearing this, but he carefully looked at it for a while. Fortunately, his eyesight was very good after his bloodline transformation. Even if the symbols were only the size of rice grains, he could see them clearly.

As Zhang Chen observed, the crystal core in his heart suddenly trembled slightly, and the speed of blood flow in his body gradually increased. In the space of a breath, Zhang Chen's heart was beating like a war drum, which seemed particularly clear in this empty stone chamber.

"I'm telling you, kid, don't look at it. If something goes wrong, I'm afraid there will be big trouble. Don't get possessed and drag me, the old ancestor, into it," the fox spirit heard the rapid heartbeat in Zhang Chen's chest and immediately became anxious, quickly shouting.

Unfortunately, she didn't have Zhang Chen's order and couldn't move at all. She couldn't wake Zhang Chen, so she could only shout at him.

At this time, Zhang Chen's eyes were bloodshot, and he was staring at the symbols on the wall. He seemed to be bewitched, his eyes firmly glued to the thousands of rice-grain-sized runes. Then, with Zhang Chen's rapid heartbeat, the veins on his forehead bulged, and his skin was also crimson, looking like a cooked prawn.

"It's over!" Fox Fairy Nan Nan saw Zhang Chen's abnormality and couldn't help but feel sad: "My Fox Fairy Nan Nan is suffering! If this kid dies, I will have to be buried with him! If he doesn't die and becomes paralyzed, wouldn't I have to serve him, feeding him and cleaning his waste? If he becomes mentally deranged and becomes a madman, wouldn't I have to accompany him in those crazy things? Where will I, the old ancestor Fox Fairy Nan Nan, put my face?"

Thinking of that tragic future, Fox Fairy Nan Nan felt sadness from the bottom of her heart: It's uncomfortable! I want to cry!

"Wake up! Don't get trapped! You are a human, don't get trapped! Just be kind and pity me, the old ancestor Fox Fairy! What kind of karma have I created! Did I just eat a little rice from your house? Do I have to serve you like a horse for the rest of my life?" Fox Fairy Nan Nan looked at Zhang Chen, constantly muttering curses.

Unfortunately, Zhang Chen couldn't hear Fox Fairy's words. At this time, Zhang Chen's vision had been glued to the runes. As his vision came into contact with the runes, the Qi and blood in his body began to run wild. The crystal core flowing in his blood had now turned into a vortex, swallowing the blood around him, and then constantly using Qi and blood to simulate runes. However, the simulated runes quickly collapsed in the crystal core, turned back into Qi and blood, and then simulated again, and then collapsed.

Repeating this cycle endlessly, Zhang Chen's complexion became paler and paler. His originally flushed face suddenly lost its color, and his body stood in front of the stone wall, swaying constantly, as if he could fall to the ground at any time.

Zhang Chen stood there for three days. His skin was pale and completely devoid of blood, and even his heart seemed to have stopped beating. The fox spirit could no longer hear any heartbeat.

At this time, there was no blood in Zhang Chen's body. Only the crystal core was placed in the shriveled and withered heart, its silver light flashing, as if some kind of strange change was taking place.

At a certain moment, strange symbols suddenly appeared on the crystal core. There were very few symbols, only one hundred and twenty, which seemed much simpler compared to the thousands on the stone wall. The one hundred and twenty silver runes were combined together, according to some unique melody, engraved in Zhang Chen's crystal core.

Zhang Chen's crystal core was only the size of a rice grain, which was already small enough, but the one hundred and twenty runes were even smaller, as if they were etched into the microscopic world of the crystal core, occupying less than one ten-thousandth of the entire crystal core.

Then, with the engraving of the runes, the crystal core actually turned silvery-white after a burst of flashing.

That's right, Zhang Chen's crystal core directly turned silvery-white from a transparent crystal.

Then, the crystal core vibrated slightly, and drops of blood quickly flowed out of the crystal core. Then, Zhang Chen's heart resumed beating, and the whole person seemed to come alive.

"Huff ~"

A long sigh broke the heavy atmosphere in the stone chamber. Even the cursing fox spirit couldn't help but shut up, her eyes full of anticipation as she looked at Zhang Chen. She hoped that Zhang Chen was not crazy or disabled, so that she, Fox Fairy Nan Nan, would not have to be a servant to others.

Fortunately, Zhang Chen was indeed not crazy. He was still intact, but the way he looked at the mural was a little strange.

"Are you okay?" The fox spirit leaned forward and looked at him expectantly, her voice a little nervous.

"I'm okay!" Zhang Chen shook his head.

Zhang Chen replied, then turned to look at the fox spirit, his voice full of puzzlement: "Are you sure that observing this pattern can strengthen the soul?"

This mural and these symbols are very strange! They actually involve another kind of mysterious power.

It seems that I can become a vampire bat!
