Under the incantations and spellcasting of Han Li and Dao Ancestor Leng Yan, the five spirit treasures emitted brilliant five-colored light, from which countless five-colored runes flew out, swirling around the spirit treasures.

The five-colored light rolled and intertwined in mid-air, quickly merging together to form a huge five-colored light sphere.

Deep within the light sphere, the five spirit treasures formed a circle, spinning rapidly.

With each rotation, the five-colored light sphere grew larger, quickly reaching a hundred zhang in size, its dazzling five-colored light almost obscuring the sun.

This scene left Lu Yuqing, not far away, dazzled and mesmerized, her apricot mouth slightly open.

At this moment, Han Li and Dao Ancestor Leng Yan simultaneously raised their hands, each striking a magic seal towards the light sphere.

"Chi la" sound!

A five-colored beam of light suddenly shot out from the center of the light sphere, striking the starry sky light curtain.

Upon contact, the star river flowing on the surface of the starry sky light curtain remained unaffected. From a distance, it looked as if a five-colored passage connected to the vast starry sky.

Han Li and his companion chanted incantations, circulating the Great Five Elements Spirit-Gathering True Light technique. The five-colored light beam immediately intensified, with dazzling five-colored light flowing within.

These lights then gathered together, transforming into five-colored light arrows, each about ten zhang in size, and then suddenly rained down, striking the starry sky light curtain.

Rumble!

The originally calm surface of the star river shook violently. Starry arrows and light intertwined, instantly creating clusters of five-colored light, spinning rapidly, and countless stars were swallowed, emitting continuous bursts of loud explosions.

The starry sky light curtain rumbled and shook, its starlight quickly dimming. The originally thick light curtain rapidly became thin.

Upon seeing this, Han Li's heart stirred.

This starry sky light curtain seemed extremely mysterious, but its interior was so fragile. They had only just begun, and the light curtain was already unable to withstand it.

Although he was quite surprised, he did not stop his movements, continuing to cast spells.

Under the frantic flickering of the five-colored light beam, more five-colored light arrows emerged and shot down.

As time passed, the starry sky light curtain became increasingly thin. After only a quarter of an hour, only a thin layer remained.

Han Li's eyes flashed, and the magic seals in his hand changed. Almost at the same time, Dao Ancestor Leng Yan beside him made the same action.

The five-colored light beam suddenly brightened, and countless light arrows emerged, then merged into one, transforming into a giant arrow about a hundred zhang in size, with streams of five-colored light rolling up and down on its surface.

Accompanied by an ear-piercing screech, the five-colored giant arrow crashed down, striking the starry sky light curtain.

With a earth-shattering roar, the starry sky light curtain could no longer withstand it. Large patches of stars and star rivers collapsed within, and the light curtain shattered inch by inch.

Seeing this, Han Li waved his hand.

The five spirit treasures in mid-air dispersed. The three spirit treasures flew into his sleeve, disappearing from sight.

The other two spirit treasures also transformed into two streams of light, which Dao Ancestor Leng Yan caught with a wave of his hand.

With the restriction gone, the original courtyard was clearly revealed, and a rich spiritual Qi and herbal fragrance wafted over.

Han Li's figure flickered, and he immediately flew down. Dao Ancestor Leng Yan and Lu Yuqing naturally followed closely.

The moment the three of them landed in the courtyard, the stone pillars in the four corners of the courtyard suddenly lit up with clusters of starlight. Points of starlight reappeared on them, and streams of spiritual light shot out, intertwining and wrapping around each other in mid-air.

In almost one or two breaths, the starry sky restriction above the courtyard reformed, but only as a thin layer.

As the array patterns on the four stone pillars flickered, a stream of starry sky power emerged in mid-air, falling down and merging into the stone pillars.

The starry sky restriction flickered slightly, slowly becoming more solid.

Han Li raised his head, glanced at the starry sky restriction, and frowned slightly, as if realizing something.

He then shook his head, withdrew his gaze, and looked towards the medicinal field beside him.

The medicinal garden within the courtyard was divided into different areas, separated from each other by barriers of green jade.

Each area was shrouded in various colored restrictions, within which grew various spiritual herbs and flowers.

Han Li turned his gaze to a medicinal field several zhang in size beside him.

This medicinal field was surrounded by a layer of faint red restriction. Within it, dozens of red spiritual herbs, each about two chi tall, were planted.

This herb was entirely crimson red, its leaves oval in shape, and its apex bore a palm-sized bright red flower, looking like a burning flame.

Even through the restriction, one could sense the astonishing fire-attribute spiritual power fluctuations emanating from this herb.

"Raging Flame Grass..." Han Li's heart stirred.

This crimson spiritual herb was called Raging Flame Grass, a rather famous fire-attribute spiritual herb that could be used to refine some top-grade fire-attribute pills, even fire-attribute Dao pills.

And the reason why this grass was famous was due to one of its characteristics, namely, once its age exceeded 100,000 years, it had a considerable chance of giving birth to a trace of fire-attribute law.

Apart from some special spiritual herbs and medicines, not many could spontaneously give birth to the power of law, and most required hundreds of thousands of years of medicinal age, but this Raging Flame Grass was an exception.

Although even if this grass gave birth to the power of law, it was not very strong, but containing the power of law allowed it to be used as medicine to refine Dao pills. Coupled with the low age requirement, it naturally became the ideal object for major forces to cultivate alchemists.

However, judging by the size of these Raging Flame Grass, they were at least 300,000 to 400,000 years old, and the fire-attribute law power born within them was naturally far from comparable to those of 100,000 years.

In addition, if he had the time in the future, he could use the palm bottle to further increase their medicinal age to 500,000 years. Such a batch of spiritual herbs containing rich fire-attribute laws would be of unimaginable value.

Han Li did not rush to pick this spiritual herb, turning around and walking towards other medicinal fields. After all, it seemed that no one had been here for a long time, and there must be many other valuable natural treasures more valuable than the Raging Flame Grass.

At this moment, Dao Ancestor Leng Yan and Lu Yuqing also walked away with pleasant surprises, each searching.

Han Li quickly stopped beside a medicinal field. In this medicinal field were dark purple spiritual herbs, only half a chi tall, very slender, and shaped like wheat seedlings.

A somewhat strange smell emanated from this grass, a fragrance mixed with a slightly pungent odor.

Han Li stared intently at these purple spiritual herbs, not paying any attention to the strange smell.

This grass was called Zenith Grass, and it was very famous in the Northern Cold Immortal Territory.

He had seen a record in a book that there was a Nightglow Island in the northernmost part of the Northern Cold Immortal Territory. A flying spirit beast called the Nightglow Spirit Falcon lived on the island. The most powerful one was only at the Integration Stage, and there were not many of them, so no one had paid attention to them.

Later, a rogue True Immortal cultivator accidentally captured a Nightglow Spirit Falcon on Nightglow Island and turned it into his own spirit beast.

Although this Nightglow Spirit Falcon had a low cultivation level, it had extremely strong eyesight and could actually see situations tens of thousands of miles away. This True Immortal cultivator was overjoyed and made a name for himself with this bird.

Later, this matter was leaked by chance, and many cultivators were immediately attracted to Nightglow Island to capture this Nightglow Spirit Falcon. However, they soon discovered that these Nightglow Spirit Falcons had ordinary eyesight and were not as powerful as rumored.

The True Immortal cultivator was surprised and came to Nightglow Island again to investigate the matter. Later, he discovered that there were several spiritual herbs growing near the nest of the Nightglow Spirit Falcon he had captured. His Nightglow Spirit Falcon had become so powerful because it had swallowed this spiritual herb.

After this matter spread, these originally strange-smelling herbs suddenly became famous and were named Zenith Grass. Their reputation quickly resounded throughout the Northern Cold Immortal Territory, attracting countless people to search for and pick them.

It was just that Zenith Grass grew slowly and had strict requirements for the environment. It was originally very rare, and it had been picked by countless cultivators, becoming increasingly rare. To this day, it had become extinct and had not appeared for nearly a million years. He did not expect to see it here.

Moreover, these Zenith Grass in front of him were at least 200,000 to 300,000 years old, making them extremely valuable.

A hint of joy flashed in Han Li's eyes. He looked at them a few more times before shifting his gaze and looking at the other medicinal fields beside him.

"Phoenix Pattern Flower!" "Silver Moon Ambrosia!" "Glittering Dew Grass!"

He quickly checked more than a dozen medicinal fields and exclaimed in surprise at these extremely precious names of spiritual medicines, many of which had become extinct in the outside world. His eyes became brighter and brighter.

Phoenix Pattern Flower and Silver Moon Ambrosia, among other spiritual herbs, contained extremely astonishing spiritual power and were excellent materials for refining constitution-strengthening pills.

Moreover, these spiritual herbs in the medicinal fields were all hundreds of thousands of years old, with extremely abundant medicinal power. Using them to refine True Immortal-level pills would be too abundant, and they should be able to refine Golden Immortal-level pills.

In addition, there were several spiritual herbs in the medicinal field that Han Li could not name with his current knowledge and experience.

These unfamiliar spiritual herbs were also full of spiritual power, containing spiritual light, and seemed to be extremely extraordinary.

Han Li was delighted in his heart, this medicinal garden really did not disappoint him.

Boom boom boom, a series of loud noises came from not far away.

Han Li looked up and saw that Dao Ancestor Leng Yan and Lu Yuqing had already begun to break the restrictions on those medicinal fields.

It was just that the restrictions in these medicinal fields seemed ordinary, but they were also exceptionally tough.

The two of them bombarded them repeatedly, but were unable to break them for a while.

Seeing this scene, Han Li did not hesitate and flicked his sleeve.

Seventy-two Green Bamboo Bee Cloud Swords surged out from his sleeve, and after circling in the air, they transformed into a verdant sword formation, enveloping several medicinal fields.

He chanted incantations and fully activated the sword formation.

Buzz buzz buzz!

Countless incomparably sharp sword Qi emerged and slashed at the medicinal field restrictions.

The Green Bamboo Bee Cloud Sword Formation, fully activated by Han Li, was extremely powerful. These restrictions trembled violently, and their light quickly dimmed.

After a few breaths, these restrictions shattered with a boom.

Han Li waved his sleeve again, and hundreds of dark yellow bean-sized objects shot out, then transformed into hundreds of Dao soldiers.

He waved his hand and released a dazzling blue light, which swept across the ground.

As the blue light dissipated, hundreds of jade boxes and jade caskets were revealed.

"Collect all these spiritual herbs." Han Li instructed indifferently.

Upon hearing this, these Dao soldiers took the jade boxes and quickly became busy.

"Dao soldiers!"

Dao Ancestor Leng Yan had just managed to break the restriction on a medicinal field and was collecting the spiritual herbs one by one when he heard the commotion and looked towards Han Li, his face once again showing shock.

Han Li's strength had already shocked him greatly, but he did not expect that he would also know this difficult and laborious Dao soldier technique, leaving him at a loss for words.
