The Demon Slayer Martial Saint Begins with Insect Refining

Chapter 398 A sudden turn of events
Su Yan climbed the sixth step and stepped through the doorway, as if he had passed through a special space.

The sixth floor is not large, only three to five hundred square meters, which is several times smaller than the previous floors.

The items here are divided into only three categories: spiritual treasures, rare items, and natural treasures. The distinction between them is obvious at a glance.

There are very few things that can be called sacred items, and their miraculous effects are difficult to categorize more precisely. Therefore, there are actually the most categories of rare items.

"As expected, there is no Xuan Shan Star Core."

Among rare and precious materials, there are many that can trigger the transformation of bloodlines, such as the Nine-Aperture Sacred Heart Fruit, but there is a lack of things like the Mysterious Mountain Star Core.

Such treasures are indeed rare, but they still exist in some great secret realms and dangerous places in the Wild Martial Realm.

However, very few Xuanshan Star Cores rely on meteorites falling from the sky and forming sacred mountains over the course of countless years.

"The Divine Fiend Locust, the Ancient Spirit Realm Insect, the Spring and Autumn Withering and Flourishing Insect, and the Moon-Eating Insect have all reached maturity. The Myriad Fiend Dragon Soul Grass and the Secret Realm Origin Crystal are both suitable. If I could obtain its bloodline, I would enter the metamorphosis stage even faster. However, this metamorphosis..."

The more ferocious insects you raise, the more materials you need for molting, and those materials become extremely precious. It's likely that the waiting time for the necessary materials will become longer and longer in the future.

Thinking about all this, Su Yan felt a sense of helplessness; this was the inevitable future that the bloodline transformation would bring.

"Fortunately, being restricted in bloodline does not mean being restricted in strength. The bloodlines of the Divine Fiend Locusts are not low to begin with. They are at least fifth-tier beast kings, and it is even possible for them to become sixth-tier demon saints."

Since there were no materials for transformation, Su Yan needed to carefully consider what he needed to exchange for a sixth-tier sacred item.

Taking Dao soldiers as an example, once they reach the sixth-order Saint rank, their power becomes incomparable, often possessing the power to destroy cities and countries.

Even with the Myriad Insect Prison Tower and the Myriad Insect Star-Eating Sword in his possession, Su Yan would still find it difficult to truly resist a sixth-tier holy weapon.

"We could take a sixth-tier holy weapon as one of our trump cards."

Thinking this, Su Yan walked past the dozen or so sacred weapons and carefully looked at their descriptions.

The sacred weapon is the martial saint's weapon.

At this level, it's rare for a master blacksmith to leave a finished product unused.

Most of them are weapons left behind after the Martial Saints refined them, due to reasons such as passing away in meditation or dying in battle.

For example, the first sacred weapon is described as: Crouching Tiger Overlord Halberd, a sacred weapon obtained from the secret realm of the Sacred Tomb of Tianyuan Prefecture. Investigations reveal it to be a sacred-grade Dao weapon of the Tiger Venerable Martial Saint from 50,000 years ago. It was forged from Tiger God Stone…

Each sacred-grade weapon possesses its own unique laws, which are part of the martial saint's enlightenment.

If a martial artist is not a good match for a sacred weapon, it is difficult to unleash its full power. This is why more than ten sacred weapons are still here.

Su Yan examined each item one by one. The Crouching Tiger Overlord Halberd was somewhat compatible with him, since it had the Golden Body of the Subduing Tiger King as its foundation, and the power of the tiger's fierceness could naturally unleash the might of the sacred weapon.

However, he already possessed another weapon, so he preferred a defensive holy weapon.

"Wait... what's this?!"

Su Yan's gaze swept over a pair of heavy hammers—the Primordial Mountain-Destroying Hammers, hammers heavier than mountains and capable of crushing mountains and seas, sacred-grade Dao weapons forged from the core of the Xuan Mountain Star...

"After the darkest hour comes the dawn; the material for the Primordial Mountain-Destroying Hammer is actually the Mysterious Mountain Star Core. I wonder if it's still of any use..."

Although some doubts remain, the current situation seems more likely than aimlessly trying one's luck outside.

"That's it."

After selecting the Saint-grade Dao Weapons, Su Yan glanced back at the Great Li Treasure Vault and muttered to himself, "If all these things were in my hands, the evolution of the ferocious insects would be much easier."

Returning to the entrance via the same route, the chief supervisor in charge of guarding the area looked somewhat surprised to see Su Yan emerge so quickly.

"Has the Marquis of Champion made his choice? According to custom, the Marquis of Champion can stay inside for an hour, and there is still time left."

"No need, I've already made my choice."

After Su Yan finished speaking, he showed him the selected items, and the head eunuch's expression became even more strange.

Although he was a martial artist who had trained his body physically, as far as he knew, this person should be the one who controlled ferocious insects.

But to now exchange it for a pair of giant hammers is truly unbelievable.

However, the eunuchs trained in the palace were naturally cautious in their words and actions, so they didn't say much, only calmly saying, "The verification is correct, Marquis Champion can leave." Su Yan left the palace and went straight to the Long family residence.

Although Emperor Lihe of the Dali era bestowed upon him a marquisate, he had not yet ordered anyone to manage it. Although there was a formation, no one was ordered to control it, so living there would be inconvenient.

So he asked his master for help, and then began to gradually bring in people from the Sacred Insect Path.

Upon returning to the Dragon Mansion, Su Yan immediately retrieved the golden relic and the beast king's corpse.

At this moment, the Blood Bone Centipede King was also released, its enormous blood-red body almost filling the entire courtyard.

This is even after it has shrunk in size; otherwise, its hundred-foot size would probably be enough to break through the entire courtyard.

Su Yan took out the Concealing God Banner and threw it into the air. Instantly, the banner emitted blue arcs of electricity, which transformed into a barrier that enveloped the entire courtyard.

Although spiritual energy was still flowing inside and outside the courtyard, the special spiritual power of the Hidden God Banner concealed everything. From the outside, the courtyard appeared empty, and no trace of the Blood Bone Centipede King's aura could be detected.

"The Blood Bone Centipede King is already in the late stage of the fourth rank. If this transformation is successful, I wonder if it will break through to the fifth rank."

Thinking this, he patted the Blood Bone Centipede King's ferocious head: "Eat it."

The Blood Bone Centipede King immediately opened its blood-red maw and swallowed the golden relic and the beast king's corpse in front of it.

With each bite, its aura grew stronger, and the power of the Ferocious Insect Cauldron continuously intertwined with its body, allowing it to completely devour the molted creature and quickly transform into a giant blood-red cocoon.

As power continues to gather, the transformative force is causing the Blood Bone Centipede King to undergo a dramatic change within its cocoon.

Su Yan took out the remaining Yuan Stones from the Insect Realm space. They were all second- and third-tier Yuan Stones, which were worth about 20 million first-tier Yuan Stones.

He frowned slightly: "We're running out of Yuan Stones."

With his alchemy skills and the supply from the Sacred Insect Path, he wouldn't be short of spirit stones.

Based on the current trend of the Sacred Insect Path's goods being transported to the four prefectures, he can receive at least tens of millions of yuan worth of stones every month.

However, he needs to constantly replenish the spiritual energy levels of his inner world and the insect world with these elemental stones to ensure that they match the expansion level.

At the same time, the use of elemental stones is also indispensable in the cultivation of ferocious insects.

With increased expenditures, it's natural to encounter times when cash flow becomes tight.

"I'll go back to Lingnan Prefecture later."

Su Yan focused his attention on the ferocious insects. He was running out of spirit stones, but he would get more from the Sacred Insect Path later. If that wasn't enough, there were many Buddhist and Taoist sects in the thirteen prefectures of Dali, as well as many filthy forces that were affiliated with them. He might as well take some from them later.

Thinking this, Su Yan also took out the Wind and Thunder Insect and fed it the Wind and Thunder Divine Dragon Wood.

With flashes of wind and thunder and converging electric arcs, the aura of the Wind and Thunder Insect was also constantly increasing. The electric arcs were faintly tinged with a purplish-black color, and its strength was also constantly improving, faintly stepping into the late stage of the fourth rank.

As time passed, after the Wind and Thunder Insect devoured the Wind and Thunder Divine Dragon Wood, its aura stabilized at the late stage of the fourth rank, and its wind and thunder power completely transformed into purplish-black lightning.

The Wind and Thunder Insects, guarding the Dharma on either side, were currently digesting their own power.

Three days later, the Yuan Stone in the courtyard had been completely absorbed by the insect cocoons and turned into dust.

At this moment, the cocoon began to crack, and a red light shot into the sky. A thick, bloody stench enveloped the entire courtyard almost instantly.

The vegetation withered, and the artificial hills and paving stones were corroded by the bloody aura. A thick mass of blood gushed out like a tsunami.

Blood surged, concealing a pair of sinister insect eyes.

The blood re-coalesced, transforming into a blood-red centipede. Its carapace solidified, its barbs menacing, and endless blood coiled around its body, as if it were its domain.

[The Bloodbone Centipede King has completed devouring its molted form and has advanced to the Blood Prison Demon Centipede.]

Using blood as a curse, like a demon, like a god.

Su Yan only sensed it slightly, and immediately his face lit up with joy. At this moment, the Blood Prison Demon Centipede had already crossed the fifth rank and become a beast king.

A ferocious insect with pseudo-saint-level bloodline and fifth-order power.
