Lord of Bones

Chapter 710: Past Promise
Li Yuan stared at these strange patterns, curiosity and amazement in his eyes.

Although these patterns appear to be chaotic, they seem to follow some profound rules.

Fortunately, there are some brief notes in the gaps between the lines.

The annotations were written in ancient characters, allowing Li Yuan to gradually understand the meaning behind those strange patterns.

As he read deeper, he seemed to be brought into a whole new world.

"It's... a sword formation!"

Li Yuan's heart suddenly shook, as if he was hit by an invisible force, and his eyes instantly lit up like stars.

He stared closely at the ancient book in his hand. The strange patterns and brief annotations were like keys, slowly opening the door to the mysteries of the sword formation.

Each pattern seemed to contain the sharpness of the Earthly Blade and the mystery of the sword formation, making him deeply trapped in it, unable to extricate himself.

The air around him seemed to freeze, with only the sound of Li Yuan's heartbeat and the subtle sound of turning pages.

He forgot the passage of time and immersed himself completely in the world of sword formations presented in the ancient books.

There, the Earthly Blade is not only a sharp blade, but also the key to building a sword formation and controlling the battle situation.

It was unknown how long it had passed before Li Yuan slowly pulled himself out of the contents of the ancient book.

He gently closed the ancient book, with a thoughtful and excited look in his eyes, and said to himself:
“It turns out that these few pages of the book are the problems and insights that Emperor Yin Lei encountered when he was exploring the layout of the Earth Demon Blade sword formation.

“Although he was not able to fully comprehend it, these difficult points provided me with valuable ideas and inspiration.”

Li Yuan stood up and glanced around the jade platform. There were a variety of jade display cabinets with various scrolls of Yuanshu, all of which were related to Wen Yuanshu.

However, at this moment, Li Yuan's mind was already occupied by the idea of ​​how to use the Earthly Evil Blade to set up a sword formation.

Although those scrolls of tattoo art are tempting, they have temporarily lost their appeal.

He began to carefully sort out the information in the ancient books in his mind, trying to transform those strange patterns and annotations into actual sword formation layouts.

"Using the Earthly Blades to set up the sword formation is a profound understanding and application of the rules of heaven and earth." Li Yuan thought to himself, "Even Emperor Yin Lei can only linger at the threshold.

"I want to forge my own path and create my own sword formation!"

As his thoughts flew, Li Yuan seemed to have found himself in a battlefield filled with sword lights.

He controlled the Earthly Blade, guided by his heart and moved by his mind, and countless blade shadows shuttled and intertwined in the air.

.........

The following days.

Li Yuan was immersed in the exploration of the mysteries of ancient books and the Earthly Blade Sword Formation.

As he studied the ancient books in depth, he gradually discovered some subtleties that even Emperor Yin Lei had never touched upon.

Those seemingly chaotic patterns began to come alive in his eyes, guiding him like stars to find direction in the maze.

Time flies, and several months have passed in the blink of an eye.

Li Yuan's life in the hall was monotonous but fulfilling, and his efforts finally paid off.

some day.

He activated the Earth Demon Blade, which flew with his thoughts and eventually formed a simple sword formation in the air.

Although this sword formation is still crude and its power is limited, for Li Yuan, it is an important milestone in his journey of using the Earthly Evil Blade to set up a sword formation.

After several months of hard training, Li Yuan's mastery of the sword formation became more and more proficient.

An unprecedented rumbling sound was heard in the Jade Hall, as if thunder had descended from the sky.

Li Yuan's body was as fast as lightning, shuttling between the Earthly Blades, and each Thunder Blade was shining with colorful thunder.

They were arranged in a mysterious pattern in the air, forming a heart-pounding sword net.

"boom--"

A powerful aura suddenly erupted, and the entire hall trembled.

Li Yuan stood in the center of the sword formation, looking at the thirty Earth Demon Blades circling and dancing in the air, his face revealing an unconcealable joy and pride.

"It's done!" he whispered to himself, "Finally increased the power a little.

“I can then polish it in detail and create my own sword formation.

"I spent too much time on the sword formation. I should improve my skills."

.........

Li Yuan sat on the mat and looked around.

Every corner of the hall reveals traces of time and the aura of the strong.

He was thinking about how to use the place where Emperor Yin Lei once meditated to improve his own cultivation.

However, when he activated the Soul-Devouring Bone and drew upon the vital energy of heaven and earth for cultivation, he unexpectedly discovered that the space here seemed to be closed by some force.

The energy from the outside world cannot penetrate in, and it is like a pool of stagnant water, losing its vitality.

This discovery made Li Yuan frown, and a chill surged in his heart, as if a basin of cold water was poured from head to toe.

Without the nourishment of the vital energy of heaven and earth, the path of cultivation will become extremely difficult.

If one wants to improve his cultivation, he can only engrave the Yuan Array and use the Yuan Stone to practice.

"Since it is impossible to collect energy from the outside world, I will put aside cultivation for the time being." Li Yuan said secretly.

At the moment, he didn't want to spend time studying treasure refining. As for engraving Yuanwen scrolls, there was no need for that. After all, Emperor Yin Lei had left him too many engraved scrolls.

He decided to continue polishing the Earth Demon Blade to set up the sword formation.

Now the Earthly Blade is no longer a simple thunder blade, but the key to building a sword formation and improving strength.

In addition, you can also start studying the Yuan techniques left by Emperor Yin Lei.

"This place is blocked by the formation and isolated from the outside world."

Li Yuan murmured softly, his eyes wandering around, passing over the intricate, ancient and delicate array patterns.

They are like sleeping dragons, winding on the jade.

Although it is quiet and silent, it reveals a power that cannot be ignored.

He thought to himself: "If I can refine a precious elixir here, I wonder if the power of the heavenly thunder can ignore the shackles of space.

"After all, this was once the place where Emperor Yin Lei refined medicine."

Thinking of this, Li Yuan did not hesitate and immediately began to set up the formation needed for refining medicine.

The formation was completed, and the Yuan Stones were embedded in various places in his hands like stars, gradually pushing the concentration of heaven and earth energy in the hall to the extreme.

The entire space seemed to be shrouded in a faint curtain of light, and the energy was so dense that it almost condensed into liquid.

Although he had quite a few materials for refining medicine on hand, they were nothing compared to the treasures left behind by Emperor Yin Lei.

In this way, there is no shortage of materials for refining medicine.

Everything was ready. Li Yuan took a deep breath, calmed down, took out the Qiankun Ding, and began to refine the precious pill. His cultivation level was raised to the half-step transformation realm. Although his soul power did not increase significantly, the Yuan force in his body was surging like the sea, continuously providing him with the energy needed to refine the medicine.

As time went by, the temperature in the hall gradually rose, and the air was filled with an increasingly strong scent of elixir.

suddenly.

Li Yuan's state of mind seemed to be touched by an invisible force, which immediately extended his soul power perception infinitely until it touched the subtle boundary between this enclosed space and the outside world.

Sure enough, although this place is isolated from the outside world and seems to be a desperate situation for cultivation, the formation area in the hall seems to have life.

When refining medicine, they absorb energy from the outside world silently in a mysterious way.

Li Yuan could clearly feel that a thunderstorm was brewing above the hall.

Red and orange thunderclouds rolled in, and thunder rumbled one after another, as if the gods were roaring in anger.

Thick streaks of lightning cut through the sky, striking the hall's defenses with devastating power.

However, these thunders that were frightening enough to scare people in the outside world, once they entered the hall, seemed to be gently caressed by an invisible hand, becoming soft and powerless, like tamed beasts that had lost their wildness.

This discovery made Li Yuan feel indescribable joy and he couldn't help laughing out loud:

“Emperor Yin Lei is indeed a peak expert who cultivates lightning elemental energy. He can actually come up with such an ingenious way to refine medicine.

“The array of the hall is so sophisticated that it is far beyond my imagination.

“With my current attainments in formation patterns, I am unable to fully understand its mysteries.

“I don’t know whether the Emperor arranged it himself, or invited some equally unfathomable power to help.

“With Emperor Yin Lei’s attainments in lightning elemental power, he can easily resist it even if he is refining elixirs.

"Could it be that he is refining higher-level pills here?"

Li Yuan looked around, his eyes filled with curiosity and desire for the unknown, but he did not find the answer.

"Since there is such a precious land to help me, how can I waste it?" Li Yuan thought to himself, with a smile on his face, "Since the thunder has become weak here, it is the best time for me to refine the precious pill.

"I will use this time to refine more precious pills and take my alchemy skills to a higher level."

What Li Yuan wants to refine most now is the elixir that can repair Cang Feng's soul.

Although it is not a elixir, it is far superior to ordinary special-grade elixirs and is infinitely close to a elixir.

At that time, Cang Feng's cultivation had reached the peak of the Yuanshen realm, and his soul realm had even risen to the treasure realm, which was rare among the Feilong clan.

As we all know, mythical beasts are mostly known for their strong bodies.

They tend to focus on strengthening their physiques, but are less interested in cultivating their soul power.

Although the cultivation level of the divine beasts is the same as that of human Yuanzhe, there is no such thing as a half-step into the realm of transformation, only the Yuanshen realm is perfect.

Most mythical beasts are born with the ability to travel through the void and can fly freely in the sky without any control equipment.

If a human Yuanzhe wants to fly without a flying device, he can only improve his cultivation to the Half-Step Transformation Realm, so that he can barely possess some of the abilities of a strong person in the Transformation Realm.

However, even those who are half a step into the Huawen realm cannot survive in the void for a long time. After all, they have not yet truly entered the Huawen realm.

When Cang Feng tried to impact the higher level of soul power in the treasure realm, an incomparably powerful soul force suddenly descended, like a mountain torrent, unstoppable.

His original spirit was instantly damaged by the impact of this soul power, and the soul power failed to reach a higher level.

If Cang Feng's soul power can reach a higher level, it will be of great help to him in breaking through to the Huawen realm.

According to Nian Ling, in order to repair the damage to Cang Feng's soul to that extent, a top-grade elixir, Shou Yuan Dan, was needed.

However, as a divine flying dragon, Cang Feng possesses natural advantages and extremely powerful bloodline, which can make up for the low grade of the elixir.

Therefore, he did not need the top-grade elixir, the Yuan Shou Dan. Only one special-grade elixir, the Dragon Soul Yuan Shou Dan, was enough to repair his soul.

The materials needed to refine the Dragon Soul Guarding Pill are so rare that they are hard to find in the world.

Each of the five precious medicines contains the purest and most spiritual energy between heaven and earth.

The four kinds of magical medicines grow in extremely dangerous places. Finding one of them is like changing your destiny.

The seven-color green soul wood is a top-grade precious medicine. Its color is like a rainbow, and its wood is as warm and smooth as jade. It emits a faint green glow, as if it can communicate between heaven and earth.

Yuan Yao found the mysterious treasure house in Taiheng Peak of Qingmu Palace and put it in her pocket after going through numerous traps.

Li Yuan accidentally found an ice stone that was only an inch long, crystal clear and emitting a rosy glow at the Xueyue Lake in Qianjuechan Ridge. It was the Baihuan Soul Crystal.

That piece of Hundred Illusion Soul Crystal was most likely transformed from the Illusion Wave Crimson Snow Silkworm at the Half-Step Life Spirit Realm.

As for the Jinhun Diluo Lotus, Li Yuan cooperated with the Yanlin Yanque and captured it at Qianjue Chanling.

Li Yuan discovered a strange stone containing the power of ancient flame among the materials collected by Emperor Yin Lei. It emitted a blazing and endless light. It was the special precious medicine Earth Fire Amber.

Li Yuan had already prepared four of the five precious medicines needed for them.

As for the four inferior spiritual medicines, he had gained some from traveling around over the years.

The Earth Spirit Soul-Nourishing Ganoderma prefers shade and generally only grows in natural caves underground, so it is particularly difficult to find. It is a great tonic for nourishing the soul.

In the past, Li Yuan found it deep in the cave where Yuan Yao was discovered.

Cang Feng once obtained a Nine-Leaf Soul Grass, but it was stolen by the Crystal-Winged Nether Python.

Now, Li Yuan also found one here from Emperor Yin Lei.

Now, all that’s missing are the Soul Jade Fruit and the Fulong Soul Heart Ginseng.

Cang Feng once said that he had heard some clues about the Soul Jade Fruit, but whether he could obtain it successfully depended on fate and strength.

In addition to these materials, refining the Dragon Soul Guarding Yuan Dan also requires the inner elixir of a thunder-type monster. It must be a level six monster, which is a powerful beast in the Huawen realm.

For Li Yuan, he simply does not have the strength to contend with such a powerful person.

However, sixty years ago, Cangyu had already reached the peak of the middle stage of the Huawen Realm.

With her strength, it shouldn't be difficult to find a level six demon beast's inner core.

Finally, one drop of dragon blood essence from at least the late stage of Yuanshen realm is needed.

The essence of the dragon clan's power. Finding a drop of it is like mastering a little of the dragon clan's mystery.

Li Yuan asked Cang Feng to collect all the materials within two hundred years.

The main reason was that Li Yuan’s strength to refine the pill was not enough at that time, and the elixir was hard to find, like looking for a needle in a haystack.

Time flies. Sixty years have passed since I parted with Cangfeng, Cangyu and Cangyan.

At that time, Li Yuan probably would not have thought that he could overcome numerous obstacles and enter the Half-Step Transformation Realm in such a short time.

Although he now has the ability to refine the Dragon Soul Guarding Yuan Pill, the materials he lacks are all rare treasures.

Li Yuan stood in the Jade Hall, looking at the nine-colored divine flames dancing in the Qiankun Cauldron, and sighed softly:
"Forget it. I will consider refining this pill when I have truly advanced to the Huawen realm and my strength has improved."

After saying this, he stopped thinking about it and focused on refining the medicine.

Li Yuan planned to use the materials on his body and the materials left by Emperor Yin Lei to refine enough precious pills before leaving here.
