"Stay for now, and when the research is over, it's not too late to dispose of it. Pen, fun, pavilion www. biquge。 info" Mu Yu muttered, he was very curious and hot about the soul energy contained in the ghosts, if he could transform the soul energy of the ghosts into a power that could be absorbed, then it would be quite beneficial for him to cultivate the "Great Yan Divine Technique", it would not be much worse than swallowing the high-level Yun Shen Pill, and even better in some aspects!

Exhaling lightly, Mu Yu's eyes looked deeply into the distance of the dark deep hole, he licked his slightly dry lips, and continued to move forward with his palms lightly.

After continuing for more than ten miles, suddenly, Mu Yu stopped again.

The consciousness slowly spread forward, and he sensed a dried skeleton, leaning against the wall, with a slightly drooping head and a large mouth, as if he had experienced some severe pain before he died.

Mu Yu hesitated for a moment, released a mechanical bird, quickly flew to the side of the air-dried skeleton, looked at it carefully, and then walked over with a light footstep.

The skeletal skeleton, wrapped in a gray robe, held a rusty sword in one hand and a strange gesture in the other, as if it wanted to pull out some kind of magic spell, but before it could be used, it was already whining to death.

"This skeleton must be some years old, at least more than a hundred years old......," Mu Yu muttered, walking to the other side of the air-dried skeleton and removing the two storage bags hanging from his waist.

The divine consciousness imprint on it had already dissipated with the death of the owner of the bones, and Mu Yu struck out a spiritual power, and easily opened the two storage bags, shaking out all the contents of the bags.

In addition to more than 3,000 spirit stones, most of the elixirs, spirit grasses, talismans, etc., have rotted and even turned into powder, and only one of the inferior acquired spirit treasures is still very well preserved.

After some searching, Mu Yu took out a yellowed and old codex from the pile, spread it out, read it carefully, and after a while, there was a hint of sudden and happy expression on his face.

The text on it is the Yue script, and the owner of the bones is a person who cultivates the immortal realm in the Yue country, or was born in the Yue country, and later settled in the Zhao country. The only thing that interested the pastoral in the Codex, apart from a few useless trifles, was that there was a description of the dark gray ghost.

According to the codex, those dark gray ghosts are unique to the three-star demon cave. They huddle in the three-star magic cave all day long, never leaving the hole, as if this magic cave itself has some kind of limitation.

Ghosts are strong and weak, ordinary ghosts are at the level of ghost soldiers, and their combat effectiveness is roughly equivalent to that of monks in the Qi refining period. And those with slightly stronger combat power, even the early stage monks of Lian Dan can deal with it, such as the ghost general who fought with the Leaping Money Dragon, which is this kind of existence.

On top of that, it is the ghost king level, with extremely strong combat power, and the average monk in the Yudan period is not the opponent of a ghost king, only such a strong person in the middle and late stages of the Yudan can dare to say that with the help of the power of the spirit treasure, he can stabilize the ghost king.

As for the ghost king, is there a more powerful ghost spirit?

Maybe, but the number is pitiful, basically they are all pets in captivity by the power of the Demon Dao, in terms of theoretical combat effectiveness, they can barely fight with the ancestor of the Yuanying!

However, ghosts are ghosts after all, even high-level ghosts are no different from human beings. But flame and thunder have always been the nemesis of ghosts, as long as a monk in the early stage of the knot Dan is holding a thunder spirit treasure, it is enough to fight with the ghost king peak level ghost things!

Of course, the premise is that the thunder spirit treasure is at least the best acquired spirit treasure, or the level of the middle grade innate spirit treasure, the general thunder spirit treasure, for the existence of the ghost king, although there is some restraint ability, but the effect has become much weaker. Even some mutated ghost kings are basically immune to ordinary lightning and fire attacks.

In addition, the codex also said that once you kill the ghosts in the three-star demon cave, it will be like stabbing a hornet's nest, and countless ghosts will smell the special aura emitted by that ghost after it dies, and find the killer, rush one after another, and even alarm the existence of the ghost general!

Unfortunately, the owner of this skeleton made this mistake by accident, and after killing a ghost, he was consumed alive by an army of hundreds of ghosts, and his skin and flesh were eaten by a ghost general, and he died a miserable death.

Mu Yu sighed lightly, rubbed his palms, and an orange-red fireball rose, and then threw it on the body of the dried bones, and suddenly there was a strange sound of "Zizi" in his ears, and after a while, only a pile of charcoal was left in the place, and even the ashes were burned.

"Perhaps, his today is my tomorrow, but I don't know if I will be as lucky as him, and the bones after death can enjoy the treatment of cremation. Mu Yu sighed with feeling, and slowly, he shook his head and smiled self-deprecatingly. Since you have chosen this path, unless you are retreating bravely, you should move forward without regrets.

......

......

In the gloomy three-star magic cave, a figure walked quickly.

Outside, it was already morning dew, the three stars were slowly hidden in the clouds, and the scorching sun in the eastern sky was also rising over time.

However, whether it is day or night, the three-star magic cave will always be the same: silent, cold and secluded.

"Huh?" At some point, the pastor paused, and noticed some noticeable changes in the temperature of the air around him.

"Looks like it's ...... taller," Mu Yu frowned and muttered softly.

For the rest of the journey, as the surrounding temperature became warmer and higher, the ghosts along the way became scarce, and by the end, there was not even a single ghost within a few miles.

Maybe it's luck, or maybe it's some factors that are mixed in with the Leaping Money Dragon, which caused Mu Yu not to bump into a ghost general-level existence, and it seems that all the ghost general-level ghosts have run to kill the Leaping Money Dragon.

This also made a boulder that had always hung in Mu Yu's heart slowly fall to the ground, but in those bright black eyes, he still maintained extra vigilance and composure.

After walking for about two hours, suddenly, in the dark space ahead, a fiery red color appeared.

Mu Yu's eyes flickered slightly, and then he released a mechanical bird, trembling its iron wings, and flew forward.

Sneer~~

Not long after, the terrifying heat from the air melted this first-order mechanical bird, and with a wisp of divine consciousness in it, it didn't last long before it exploded into a shattered soul energy and was quickly evaporated by the heat wave.

Mu Yu's eyes sank, and he secretly smacked his tongue at the terrifying heat contained in the air.

"Even if it's the heat of the underground magma, it's just that, right?" Mu Yu muttered to himself.

After a slight hesitation, Mu Yu gritted his teeth and recited a mantra in his mouth, and a defensive spirit gang was raised, and he cast a small diamond technique, causing the brilliant golden mangs to turn into a layer of gauze and cover his whole body.

After making these preparations, Mu Yu took a step forward and walked towards the depths of the demon cave that shone with fiery red light.

In a short time, the scene in front of him suddenly became clearer, the fiery red color dispelled the previous darkness, and also made the atmosphere of silence here a little thinner, and the heat in the air also made Mu Yu's throat dry, and his lips turned from dry to chapped.

Hot!

This is the hottest time that the pastoral has ever experienced in his life!

Even a few years ago, when he was in the depths of the leyline of Xiling Kingdom, Mu Yu had never felt so hot, and compared to now, he was slightly inferior.

Beads of sweat ran down his forehead, slid down the bridge of his nose and sideburns, soaking his clothes, and in a short time, Mu Yu was like being scooped up in water, sticky and wet.

Sweat smudged his clear eyes, and Mu Yu gently exhaled a breath of hot air, wiped the sweat from his eyes, and looked down at the scene under the rift in front of him.

It was a field of orange-red magma! Countless bubbles filled the magma, and the gurgling flowers burst one by one, and more bubbles quickly appeared.

"Hey, the aura here ......" Suddenly, Mu Yu sighed lightly, stretched out his hand and grabbed a handful in the void, and suddenly, a pure pale red cyclone appeared in his palm.

"What a pure fire attribute energy! It seems to be ...... It is also very beneficial to the cultivation of the human body!" Mu Yu was surprised, slowly, a slight vortex was generated in the palm of his hand, diverting the light red cyclone, introducing a trace of it into the body, refining, and when it merged into the dantian along the specific meridians, the aura in the dantian suddenly increased by one point, which was equal to absorbing one-third of the spiritual energy of the lower grade spirit stone!!

"If I practice here for ten or eight years, even if it's a knot, I can expect it!" Mu Yu's gaze suddenly became hot, and his breathing was heavy, making the hot breath he originally exhaled even hotter.

However, when Mu Yu's gaze inadvertently caught a glimpse of a skeleton not far from him, he was stunned, and he walked over, crouched down, and looked carefully.

This skeleton is more decomposed than the skeleton that Mu Yu has seen before, and judging from the situation at the scene, the period of formation of this skeleton is about 100 years.

"Huh?" Suddenly, Mu Yu sighed softly, and his palm was wrapped in a cloud of dark golden light, as if wearing a thin glove, pressing the chest of the skeleton.

The blackened dead skin was easily peeled off, perhaps because there were too many fighting scenes experienced, causing Mu Yu to see such a disgusting and bloody scene, his expression would not be the slightest wave, and he was indifferent.

Peeling off a thin layer of rotting dead skin, Mu Yu looked intently and saw that on the sternum, there were a little fiery red markings imprinted on the white bones.

Mu Yu pondered for a moment, and his palm fingers suddenly erupted a dark golden sword light, gently on the white bones, mixed with light ashes, scraping off the fiery red markings.

With a pinch of the palm fingers, the fiery red markings turned into powder, with a terrifying temperature, "Zizi" corroded the dark gold Linggang covering the palm.

"It's so rich in fire-attribute aura!Compared to the free-flowing fire-attribute aura in the air, it's more than five times richer?" Mu Yu exclaimed, and it was only then that he understood why the owner of this skeleton had fallen here in no apparent terms.

He was burned to death by poison!

"By the way, the more intense the aura, the more it will give birth to such a thing as 'poison', such as the Cave of the Sword Sect, the cold poison is so strong that even the slightest carelessness of the foundation building monk will freeze to death and frostbite, and it is like the fire poison mixed in the pure fire attribute energy that is now free around......" Mu Yu whispered.

Thinking of this, Mu Yu felt a little afraid. If you can't wait to start practicing here like the owner of this skeleton, then it won't be long before the fire poison will quietly spread all over your body, and at that time, even if you find it, it will be too late.

Mu Yu pondered for a moment, slowly squatted down, rummaged through the skeleton for a moment, and took out three storage bags and a spirit beast bag.

The treasures in the four bags were all shaken out, except for some things that have a long shelf life, such as spirit stones, magic weapons, etc., the rest have either been decayed, or turned into powder, and some demon beasts and spirit insects in the spirit beast bag have also been dried for a long time, and with a light touch of their fingers, they will be shattered into a pile of powder.

"It's a bit of a pity, but overall, the harvest is pretty good. Mu Yu grinned, and after smiling lightly, he concocted a fireball and burned the skeleton to ashes.

Immediately, Mu Yu sat cross-legged, closed his eyes for a while, and his heart gradually calmed down, and the upset caused by the heat in the air was also quietly suppressed in the depths of his soul.

With a pinch of his hand, he spread it out and rushed up, and began to guide the pure fire attribute energy that was free in the air, circulating along a specific meridian, and converging into the dantian.

The cultivation plan set by Mu Yu for himself is to cultivate for an hour, rest for half an hour, and take advantage of this rest to expel a small amount of fire poison from the body.

Although this will greatly slow down the cultivation process, for the sake of his own life, Mu Yu doesn't want to become the owner of the skeleton that has just been cremated by himself, and die here in no apparent terms.

Time flies, and about three days have passed in the blink of an eye.

At a certain moment, Mu Yu, who was originally sitting cross-legged, suddenly opened his eyes, and the depths of his dark and bright eyes revealed a faint demonic fiery red.

"Alas, although I deliberately compressed the cultivation time, and each time I used half an hour to expel the fire poison in my body, but over time, there was still a small amount of fire poison, which precipitated in the body......" Mu Yu smiled bitterly, took out a ley of earth vein pill from his arms, and after swallowing it, the faint fiery red in the depths of his black eyes became a lot lighter, but there was still an extremely faint fiery red residue.

"These three days of penance have undoubtedly made my cultivation even more refined, and it is worth seven months of cultivation in the outside world...... After four days of cultivation, let's comprehend the Dragon Crouching Tiger Sutra. Mu Yu secretly said in his heart, he felt that in such an environment, he could persist for about a month, and after reasonable planning, the first seven days would be used to cultivate aura, and the next ten days would be used to comprehend the "Dragon Crouching Tiger Demon Sutra", as for the rest of the time...... Strive to master this refining method preliminarily!
