Mortal: Even with a Heavenly Spiritual Root, I still have to try and get my hands on the Little Gree

Yin-Yang Cave is one of the ten most dangerous places in the Great Jin Dynasty. It is extremely dangerous, so few cultivators usually come here.

But today, inside the Valley of Ten Thousand Poisons, the main entrance to the Yin-Yang Cave, a hurricane carrying poisonous substances has swept through the land.

The one who caused this phenomenon was Mu Yu.

At this moment, Mu Yu was holding a small purple wooden cauldron and was frantically harvesting all kinds of poisonous insects and creatures in the Valley of Ten Thousand Poisons.

This treasure is the Myriad Poisons Condensing Yuan Cauldron, specially crafted by Mu Yu.

Although this treasure is only of ordinary ancient treasure quality, it is perfectly suited for storing poisonous creatures and insects.

If time allowed, Mu Yu could even use this cauldron to pack up and take away all the poisonous insects in the entire Valley of Ten Thousand Poisons.

Unfortunately, things won't go that smoothly. Those poisonous insects, though ferocious, aren't stupid; they won't let him slaughter them at will.

Later on, some of them will definitely escape.

But now...

Around Mu Yu, there were eighteen flying purple-striped scorpions, each over ten feet tall, slaughtering various poisonous insects in the area.

The two smaller scorpions following behind each flying purple-striped scorpion were frantically feeding on various poisonous creatures.

Each mature Flying Purple-Striped Scorpion possesses strength comparable to that of a Nascent Soul cultivator, and its hard shell is strong enough to withstand attacks from late-stage Nascent Soul cultivators.

Therefore, when facing these poisonous insects in the Valley of Ten Thousand Poisons, these eighteen flying purple-striped scorpions could almost be said to have a crushing advantage.

However, the poisonous creatures in the Valley of Ten Thousand Poisons are not to be trifled with. Due to the excessive slaughter by the Flying Purple-Striped Scorpions, all the poisonous insects in the entire Valley of Ten Thousand Poisons went on a rampage.

This level of venomous insect wave has reached an extremely terrifying level, enough to easily kill any Nascent Soul stage cultivator who enters it. Even some late-stage Nascent Soul stage cultivators dare not approach it easily.

But at this moment, Mu Yu was hiding in the formation, leisurely collecting the poisonous insects that had died from the flying purple-striped scorpions.

"If Fellow Daoist Mu can collect all the poisonous insects in the entire valley, it should be enough for those thirty-six small flying purple-striped scorpions to grow to adulthood."

Silver Moon's voice came from her right wrist. Even though she had regained some of her memories, she had never seen such a scene of swarming poisonous insects before.

"It won't be that easy. Although these poisonous insects haven't developed intelligence yet, they're not the kind of fools who would willingly throw their lives away. I estimate they'll disperse soon."

As if to confirm what Mu Yu had said, the swarm of poisonous insects, which resembled a wave, dispersed after about a third of them were destroyed, and could no longer reassemble.

Upon seeing this, Mu Yu immediately activated the Myriad Poisons Condensing Cauldron in front of him, collecting large swarms of poisonous insects.

These are all food for those young flying purple-striped scorpions.

In the end, Mu Yu only managed to collect about half of the poisonous insects in the entire Valley of Ten Thousand Poisons. The rest had scattered and fled, with some occasionally disappearing into the soil or into the crevices of rocks.

The Valley of Ten Thousand Poisons, shrouded in poisonous creatures year-round, finally saw a sliver of sunlight at this moment.

Seeing this scene, Mu Yu had no choice but to reluctantly withdraw the Myriad Poisons Condensing Yuan Cauldron.

Unless it takes months or even years to collect them bit by bit, given the current distribution of poisonous insects, Mu Yu has no choice but to give up on continuing to collect them.

After retrieving the thirty-six small flying purple-striped scorpions into his spirit beast pouch, Mu Yu turned to look at a certain spot behind him and said:

"Fellow Daoists, you've been watching for so long, isn't it time to come out?"

As soon as he finished speaking, Han Li and Nangong Wan appeared before Mu Yu's eyes.

"Brother Mu, it's been a long time!"

Han Li greeted her somewhat awkwardly. Although he had known that Mu Yu would suddenly appear at some point, he really did not expect to see such a spectacular scene.

One person actually managed to completely wipe out a dangerous place in the Great Jin Dynasty.

This feat is no less impressive than the legendary supernatural powers of Nascent Soul stage cultivators who could change the world.

"Oh, it's you guys..."

"Oh, Fellow Daoist Nangong has successfully advanced to the mid-Nascent Soul stage. That's certainly good news."

Mu Yu casually offered his congratulations to Nangong Wan.

Immediately afterwards, Mu Yu fixed her gaze on Fu Cheng, her eyes narrowing slightly.

"This place is the entrance to the Yin-Yang Cave."

"I have come here because of the poisonous insects in the Valley of Ten Thousand Poisons."

"But none of you practice poison arts, could it be... you're planning to search for treasure in the Yin-Yang Cave?"

"Would it be alright if I, Mu, were to come along?"

Mu Yu spoke without any politeness.

If these people are sensible, then Mu Yu wouldn't mind giving them a ride.

If they don't know what's good for them, Mu Yu can naturally search Fu Cheng's mind to get what he wants.

At this moment, although Fu Cheng and the others realized that something was wrong, they had no idea that their lives depended on the next few words.

At this moment, although Fu Cheng and the others realized that something was wrong, they had no idea that their lives depended on the next few words.

After hearing Mu Yu's words, the group led by Fu Cheng exchanged a few words and then made a decision.

"I have long admired Fellow Daoist Mu's name. Since Fellow Daoist Mu is interested, then this old man is naturally more than happy to welcome you."

"My purpose in coming here is to obtain the flesh and blood of the Yinzhi Horse, which is needed to refine the Infant Cultivation Pill..."

Fu Cheng tactfully revealed everything and sincerely invited Mu Yu to join him.

Of course, the reason he was so sensible was not only because he was wary of Mu Yu's power, but also because each person could only take one Nascent Soul Pill at most, otherwise it would be ineffective.

Therefore, Fu Cheng did not believe that such a thing would lead to him being killed to silence him.

"Nurture Pill... Not bad, my luck has indeed arrived."

"Now that I'm at the mid-stage of the Nascent Soul realm, this pill is just right for me."

Upon hearing Mu Yu's words, Fu Cheng and the others realized that this person, who had become famous in the Great Jin Dynasty in recent years and had been rumored to have killed late-stage Nascent Soul cultivators, was actually at the same level as them.

And so, Mu Yu smoothly joined them and stepped into the Yin-Yang Cave.

The Yin-Yang Cave is named after Yin and Yang because of the Yin wind within. Just now, outside, one could witness the vortex of Yin energy formed by the Yin wind, from which came bursts of ghostly wails and howls.

This strange phenomenon is not the most dangerous and terrifying Yin wind in the Yin-Yang Cave; it is simply a phenomenon caused by the strong Yin energy.

"If we were to refine some magical artifacts from here, their power would probably be quite impressive."

Mu Yu said with some emotion.

These words surprised Fu Cheng and Bai Yaoyi and the others from Xiaoji Palace.

Because in the human realm, most of the time environmental factors are not considered when refining magical artifacts; the materials used to create them are the only considerations.

The art of weapon crafting that truly involves the external environment is at best able to imitate spiritual treasures, and often only one can be produced every few years.

The replica of the magical artifact that was auctioned at the previous auction in Jinjing was already considered one of the most top-tier treasures.

"I never imagined that Fellow Daoist Mu was also proficient in weapon crafting."

Fu Cheng offered a compliment, then took out the sect's most prized treasure, the Purple Nether Pearl, which emitted a faint purple halo, isolating most of the surrounding Yin energy.

"Fellow Daoists, please note that what we are seeing now is not the terrifying Yin Wind, but simply a Yin wind formed by the condensation of Yin energy."

"I don't need to remind you of how dangerous that terrifying, eerie wind is."

After Fu Cheng finished speaking, he held a ball of purple light and slowly walked into the Yin-Yang Cave.

Mu Yu smiled, watching Han Li momentarily lose his composure because of the Purple Nether Pearl, and then secretly tried it herself.

Indeed, this treasure is quite extraordinary; it can be considered a top-grade antique.

This terrifying yin wind was something Mu Yu had considered before refining the Myriad Souls Banner, since yin spirits can only exert their strongest effect when refined into vengeful ghosts.

But why did Mu Yu change his mind and ultimately refine the myriad souls in the Myriad Soul Banner into demonic spirits?

It's very simple: the birth of a vengeful ghost requires a large amount of yin energy, and there aren't many places in Tiannan with abundant yin energy, making subsequent upgrades a problem.

But demonic energy is different. Nowadays, demonic energy from the demon realm is almost everywhere in the human world. It is not only easy to find, but also of high quality.

More importantly, the difference between demonic energy and spiritual energy is not that great. Even if demonic energy cannot be found, Mu Yu can use the Myriad Soul Banner to demonize and use spiritual energy.

However, finding Yin energy is quite troublesome, and vengeful spirits are easily restrained by various things.

For example, right now, there's the one-horned ghost being treated like a buffet by the Howling Soul Beast.

Within this Yin-Yang Cave, yin energy permeates the air, and there exists something called the terrifying yin wind, which naturally gives rise to an almost endless number of ghosts.

For Tihun, all of this is like a buffet.

Han Li might be wary of the presence of others, but Mu Yu didn't need to care at all. He simply released Ti Hun to devour ghosts. Occasionally, some talented ghosts would be taken into Mu Yu's Myriad Soul Banner to make up for the number of demonic spirits inside.

After venturing deeper into the Yin-Yang Cave for several days, they encountered more and more forks in the road. Finally, Fu Cheng suggested that they split up, and he would cast a spell on everyone to isolate them from some of the Yin energy.

Mu Yu knew exactly what was going to happen next, but he wasn't in a hurry. He refused Fu Cheng's offer to cast a spell on him, and a layer of light enveloped Mu Yu, easily isolating him from the surrounding yin energy.

"I'll go take a walk around. Just let me know if you find Yin Zhima."

After casually tossing out a sentence, Mu Yu chose a cave and entered it.

Rushing headlong along the way, Mu Yu quickly discovered the end of the road with his speed.

Unfortunately, this road is a dead end.

Most of the passages in this Yin-Yang Cave are interconnected, so encountering a dead end is considered a stroke of luck.

Perfect timing, I can practice my sword techniques briefly.

And so, Mu Yu made a sword incantation with his hands, releasing all sorts of sword energies that kept slashing at the wall in front of him.

After about an hour, Mu Yu lost track of how far she had gone before finally breaking through to another passage.

Inside, Mu Yu saw something that surprised him—the Yinzhi Horse!

"It's not the Silver-Winged Yaksha after all? Interesting..."

Mu Yu only knew that there were good things in this direction, but he really didn't expect it to be Yinzhi Horse. It seems that the Nurturing Pill has a great effect on him, and it can even reach the level of Xiaoji.

Moreover, this Yinzhi horse seemed a bit strange; it didn't run away after seeing Mu Yu.

It should be noted that the noise Mu Yu made when he used his sword energy to open up the passage was not insignificant.

A flash of lightning, and Mu Yu quickly caught the Yinzhi Horse. After inspecting it and confirming that there were no problems, he sealed it and put it into his storage bag.

After thinking for a moment, Mu Yu took out several communication jade slips and called Fu Cheng and the others over.

His goal wasn't just the Yinzhi Horse; if they were willing to wait, Mu Yu wouldn't mind refining pills in this kind of place.

It should still be some time before the opening of Kunwu Mountain.

The first to arrive were Han Li and his wife.

Next came the burly man surnamed Yuan and Bai Yaoyi from Xiaoji Palace. Not only were the men surnamed Chang and Fu Cheng the slowest to arrive, but they were also being chased by a large group of corpse wolves.

As if sensing the approach of the Corpse Wolf, the Howling Soul Beast roared and transformed into a giant ape to meet it.

Just as Tihun was fighting the giant wolf, several dried corpses appeared in the corner and attacked everyone present.

"Everyone be careful, that is not ordinary corpse energy. Corpse evil energy cannot be destroyed at all, it can only be sealed."

Upon seeing this, the person surnamed Chang quickly spoke up to remind him.

The others' expressions changed drastically, but when they saw the dried corpses that had been killed twist and reappear, they understood what the surname Chang meant.

"I will seal it..."

The burly man surnamed Yuan seemed to have some secret technique he wanted to use, but before he could finish speaking, the weeping soul abandoned its battle with the corpse wolf and ran over.

Immediately afterwards, Tihun exhaled a yellow glow from its nose, swallowing the three monsters composed of corpse demons into its belly.

After doing all this, the Crying Soul Beast joined Han Li and the others in their battle against the several enormous corpse wolves.

"Fellow Daoist Mu's spirit beast... truly possesses extraordinary abilities!"

Having witnessed Ti Hun's instant kill of the Corpse Fiend, the burly man surnamed Yuan could only speak somewhat awkwardly.

Meanwhile, with the help of Han Li and Nangong Wan, the corpse wolves had been completely killed, and Tihun was excitedly absorbing the corpse energy from their corpses.

"Alright, the trouble has been resolved."

"As for Yin Zhima, I have already found him."

"However, I am going to a secret realm here, which I estimate will be very dangerous. Even a late-stage Nascent Soul cultivator might die inside."

"So, are you choosing to stay here for a while until I finish refining the pills, or are you planning to come with me to that place and give it a try?"

Mu Yu's words caused the others to look at each other in bewilderment, completely unaware of what had happened.

Han Li, however, was prepared for this and pulled Nangong Wan to stand behind Mu Yu.

After hesitating for a while, Fu Cheng and the others decided to take the pills and return.

So, Mu Yu first expanded the space in this place, and then took out the Heavenly Mystery Palace that he had refined and released it.

The magnificent and enormous Heavenly Secrets Palace shocked everyone present, including Han Li.

The portable cave dwelling that Mu Yu has just crafted is even more powerful than the fixed cave dwellings of some of them.

Even so, Mu Yu was still somewhat dissatisfied.

"Han Li, go set up the Reversed Five Elements Formation. Although the largest one can't get out, there are still some smaller ones that are quite annoying."

After giving this instruction, Mu Yu asked Fu Cheng for the materials he had prepared to refine the Infant Nourishing Pill, and later found that he didn't have enough, so he added some more himself.

At first, Fu Cheng wanted to mention his alchemy skills, but Han Li's few words of telepathy broke his defenses, and he never mentioned his alchemy skills again.

Monster, you're not only incredibly strong, but you also know how to forge weapons and even refine pills. What is it that you can't do?

Three days later, Mu Yu successfully refined twenty-seven Infant Nourishing Pills, maximizing the proportions of the ingredients.

When Mu Yu came out of the cave, everyone except Han Li was a little uneasy because the time spent refining the Nascent Soul Pill was too short.

Mu Yu casually tossed out six pristine white jade bottles and said:

"Alright, the pill refining is complete, it went smoothly."

"Han Li, let's go..."

Mu Yu retrieved the Heavenly Mystery Mansion and then set off in one direction.

Han Li, after retrieving the array plate and flags of the Reversed Five Elements Array, followed with Nangong Wan.

After hesitating for a moment, Fu Cheng and the others decided to return.

Although they and Mu Yu were both at the mid-stage of the Nascent Soul realm, the difference in their actual combat strength was too great. Even if there were some treasures in the place Mu Yu mentioned, they were definitely not something they could covet.

Not to mention the crisis that Mu Yu mentioned, where even those in the late Nascent Soul stage might die.

If the difference in combat strength between them wasn't so obvious, Fu Cheng and the others would have gone along no matter how dangerous the situation was.

But for now, being able to obtain the Infant Nourishing Pill safely is already the biggest gain of this trip.

If we continue, we'll be courting death.

At this moment, the group of people who had already begun to move away from the Yin-Yang Cave were completely unaware that they had been given a second chance at life. They were still somewhat annoyed that they had encountered such a secret realm but had not dared to venture into it.

Meanwhile, Mu Yu had already led Han Li and Nangong Wan to a small square.

In the center of the square stood a giant, emerald-green bamboo. The top of the bamboo was completely dark, with no visible tip, while a huge magic array was set up at the bottom.

There were dozens of stone pillars around, and on each pillar, a desiccated corpse was bound with iron chains.

But what is most eye-catching is actually the green-haired humanoid monster standing under the giant bamboo.

"I never expected that you would actually come to me of your own accord."

As early as when Mu Yu stepped into the Yin-Yang Cave, the Silver-Winged Yaksha sensed the danger. Later, when the Demon Corpse's divided soul was destroyed, the Silver-Winged Yaksha became even more cautious.

As for the so-called Yinzhi horse, it was actually sent by the Silver-Winged Yaksha, but unexpectedly, they still came.

But all that came were three cultivators at the mid-Nascent Soul stage. Silver-Winged Yaksha suddenly became arrogant and could no longer care about the extremely mysterious sense of crisis he had felt before.

In reality, even if Silver Winged Yaksha believed in that sense of crisis, it would be of no use whatsoever.

The Silver-Winged Yaksha, sealed here, had absolutely no choice.
