Nine Transformations of the True Spirit.

Chen Yuan meditated and practiced in the spiritual medicine garden until four days later, when a spiritual energy storm broke out and he woke up from his meditation.

He raised his hand, made a gesture, injected a wisp of true energy into the stone tablet, and summoned a sand table.

The black evil energy that cut off the large spiritual vein rolled over and over, like boiling water, spreading violently in all directions.

The colorful barrier at the edge of the sand table lit up, and long crystal ropes extended from the large spiritual veins, interweaving into a large net, surrounding the black demonic energy.

The spiritual energy and the demonic energy collided with each other and continued to dissolve, making a hissing sound, like two entangled yin and yang fish, gradually blending into one, forming a strange light gray gas that gushed out from the earth and spread.

The protective formation became brighter and brighter, emitting colorful rays of light that swept in like a strong wind, sweeping away the gray air.

But the black demonic energy continued to expand, colliding and dissolving with the spiritual energy, forming a continuous stream of gray gas.

The colorful spiritual storm lasted for seven days until the black evil energy calmed down and the protective formation also subsided.

During these seven days, Chen Yuan stared at the sand table silently, his eyes fixed on the black evil energy, motionless.

He suddenly raised his sleeve and flicked it, and the sand table disappeared. He turned and walked out of the thatched hut, and came to the edge of the green light curtain. Still without stopping, he went straight through the light curtain and walked out of the spiritual medicine garden.

After refining the stone tablet, although he was still unable to control the protective formation and could not enter and exit the secret realm freely, the restrictions in the secret realm could no longer stop him.

These restrictions were not set up to protect the spiritual medicine garden. Their main purpose was to lock in the spiritual energy and ripen the spiritual herbs. Secondarily, they were to prevent any captive monsters from breaking in.

After the spiritual storm subsided, the blue sky was exceptionally clear, as if it had been washed by water.

All the Qi Refining disciples have left the secret realm, leaving only low-level monsters wandering around.

They have lived in the secret realm of Dongxu Mountain for tens of thousands of years, and their bloodlines have undergone significant mutations. They have adapted to the spiritual energy storms that erupt every ten years.

No monster could find Chen Yuan's trace. It only took him a quarter of an hour to reach the western part of the inner ring, above the large spiritual vein shrouded in black demonic energy.

This place is no different from other places in the secret realm, except that it is a little dimmer. Even under the sunlight, it still gives people a gloomy feeling.

Chen Yuan spread out his spiritual sense and went deep into the ground, but within a hundred feet, he was completely blocked.

After tens of thousands of years of nourishment from spiritual energy, the soil in the secret realm of Dongxu Mountain is much harder than that in the outside world.

But this distance is enough for his spiritual consciousness to reach the earth veins and the spiritual veins attached to the earth veins.

A thick layer of black air enveloped the earth veins and spiritual veins like a thorn in the flesh. The surrounding rocks and soil had been melted away to form a huge hole, like an underground cave.

Chen Yuan pondered for a moment, then activated Kunpeng's true blood. The black wings behind him spread out, and with a flap of his wings, his figure disappeared from the spot and teleported to a hundred feet underground, next to the earth vein.

At the same time, he used all his strength to circulate his true energy, and his Void Escape robes turned pure black with a silver-white glow. He then took out the Zixu Sword, held it in his hand, and stared closely at the black demonic energy in front of him.

But the black evil energy did not move at all. It just attached itself to the earth veins and flowed slowly.

Chen Yuan felt relieved, but still did not dare to be careless. His true energy kept flowing in his meridians. The silver-white light on his Void Escape robe became brighter, illuminating this huge underground cave.

He saw the full picture of the earth vein on the sand table. It was a dark yellow stone dragon covered with rough stone scales and had four claws. It was entrenched deep in the earth, and it looked lifelike.

But when you get closer, you can only see the rough and uneven body of the dragon. The huge body is a hundred feet thick, with no head or tail visible, let alone dragon claws or whiskers.

Chen Yuan came in front of the dragon, suddenly raised his hand and waved it, the purple sword flashed, and a green sword light flew towards the black evil energy.

The green sword light moved extremely fast, penetrating the evil spirit and landing on the earth veins, leaving a deep scar.

But the next moment, the earth's energy surged in, smoothed out the scars, and the earth veins returned to normal.

Chen Yuan put away the Zixu Sword and stimulated Zhu Yan's true blood. His black hair turned snow-white and Zhu Yan's true fire rose above his hands.

At this time, he was less than ten feet away from the earth vein. With a thought, a wisp of Zhuyan True Fire suddenly appeared in the black demonic energy and burned fiercely.

But after Chen Yuan waited for a while, only his true essence was lost, and the black demonic energy was still intact.

Chen Yuan frowned and continued to activate the Zhuyan True Fire, but it was still of no avail.

Next, Chen Yuan tried other methods, such as the black blade, the devouring technique, etc., but they were of no use to the black evil energy.

It was not until he bit his tongue and spurted out a drop of blood containing the power of the stars in the sky that the black evil spirit began to melt away as if it were dry wood encountering a raging fire.

But this drop of essence blood can only wipe out a few wisps of black evil spirit.

The black demonic energy that enveloped the earth veins was hundreds of feet thick. Even if Chen Yuan exhausted all his blood and energy, he could probably only eliminate one percent of it.

He took a deep look at the black evil spirit, flapped his wings, teleported above the ground, and flew into the sky with a flash of light, but his expression was a little gloomy.

He has already regarded the secret realm of Dongxu Mountain as something in his pocket, and the existence of this black evil energy is always a hidden danger.

But it is unknown how long this thing has existed. Since the Dongxu Mountain Secret Realm has not collapsed and the large spiritual veins are not seriously damaged, it is better to put it aside for the time being and deal with it later.

Chen Yuan recalled the situation on the sand table and came to the nearest spiritual medicine garden. He passed through the forbidden light curtain, swept up all the spiritual medicines, and then went to the next spiritual medicine garden.

Most of the spiritual herbs in these spiritual medicine gardens are three hundred or five hundred years old. There are fewer eight hundred years old spiritual herbs, and thousand years old spiritual herbs are even rarer. Tens of thousands of years have passed since Ziyang Sect found the flaw in the protective formation, broke the ban, and entered the secret realm to search for spiritual herbs.

At least twenty remaining spiritual medicine gardens were found by the Qi-refining disciples, and all the spiritual herbs within were looted.

After the destruction of Ziyang Sect, Dai Qing found the records about the secret realm of Dongxu Mountain in the Sutra Library and gave them to Chen Yuan.

It records three well-preserved spiritual medicine gardens, which were discovered by Qi-refining disciples who entered the secret realm in the past. However, the protective power of the restrictions was too strong to be broken.

These three spiritual medicine gardens were marked on the sand table. The restrictions that were unshakable for Qi Refining disciples became meaningless after Chen Yuan refined the stone tablet.

A day had passed when he had searched all the preserved medicinal gardens.

Chen Yuan did not simply pick the spiritual herbs, he also left seeds in the spiritual medicine garden. With the nourishment of the rich spiritual energy, they will soon take root and sprout. With the cultivation of the formation, they will be fully mature in another hundred years.

After returning to the spiritual medicine garden in the center of the inner ring, Chen Yuan carefully counted them. From other spiritual medicine gardens, he had obtained more than three thousand three-hundred-year-old spiritual herbs, more than five hundred five-hundred-year-old spiritual herbs, more than two hundred eight-hundred-year-old spiritual herbs, and eight thousand-year-old spiritual herbs.

Among the dozen or so remaining spiritual medicine gardens, there are two extremely large ones, where they grow the main medicines for refining foundation-building pills - Yin-Yang Ganoderma, Angelica dahurica, and Seven-Star Grass, with a total of more than 1,400 plants.

It seems that even in ancient times, Foundation Establishment Pills were highly valued.

Chen Yuan classified these spiritual herbs and sealed them up, leaving behind the eight thousand-year-old spiritual herbs, more than seventy eight-hundred-year-old spiritual herbs, and more than one hundred and fifty five-hundred-year-old spiritual herbs.

All the eighth-level demon pills in his hand had been refined into pills, and there were still four ninth-level demon pills left. Before entering the secret realm of Dongxu Mountain, he had also prepared the corresponding spiritual herbs.

These spiritual herbs are prepared for the future refining of Yaoyuan Pills and are relatively rare in the outside world.

Among them, there are more than a dozen eight-hundred-year-old spiritual herbs needed to refine the tenth-level Demon Yuan Pill, and their rarity is even comparable to thousand-year-old spiritual herbs.

Elder Dan Jue had never refined a level ten demon essence pill, but demon essence pills with the same properties had commonalities.

He deduced the recipes for several level 10 Yao Yuan Pills from the level 8 and level 9 Yao Yuan Pills he had refined, and left them to Chen Yuan.

Chen Yuan has already refined dozens of eighth-level demon essence pills, and the demon essence pills he uses are of various types. It can be said that his experience is richer than that of old man Dan Jue, and he has derived the recipes for more than a dozen tenth-level demon essence pills.

With these spiritual herbs, Chen Yuan can save a lot of trouble when refining the Yaoyuan Pill in the future.

After processing the spiritual herbs he had obtained, Chen Yuan stood up and walked out of the thatched hut, coming to the front of the mountain wall on the left side of the valley.

There were two tightly closed stone doors on the mountain wall. Chen Yuan raised his hand and pushed, but the stone doors did not move at all.

Chen Yuan raised his eyebrows and exerted a little force. The stone door trembled and opened backwards, but at a very slow speed.

Chen Yuan exerted more strength, using 30% of his strength, and forcibly pushed open the two stone doors that required special spells to open.

Amidst a dull rumble, the heavy stone door, which was more than ten feet thick, slowly opened, revealing a stone staircase extending underground.

Chen Yuan stepped in, walked down the stone steps, and went underground step by step, his figure disappearing into the darkness.

On both walls of the passage, there were fist-sized luminous pearls embedded, but under the erosion of time, they were all broken and lost their function.

Chen Yuan moved freely in the dark environment. After walking for nearly a quarter of an hour, he finally reached the end of the stone steps.

This is a vast stone palace with a high dome inlaid with luminous pearls, like a star map in the sky, but it has lost all light.

On the other side of the stone hall, a huge and rough stone dragon head stretched out, exuding an ancient and vicissitudes of life.

On top of the dragon's head, there is a stone platform with a stone bowl enshrined on it.

This is the source of the earth veins and also the source of the large spiritual veins. It is exactly the same as what Chen Yuan saw in the sand table.

He walked through the open stone hall, and every step he took was echoed by the sound of crisp footsteps.

Chen Yuan came to the front of the dragon head, his body flashed, he flew to the top of the dragon head, and took out a jade bottle.

In the stone bowl, there is a ball of milky white spiritual liquid, emitting a faint fragrance that is refreshing.

Chen Yuan took a light breath, and all the true energy consumed on this journey was restored to its original state.

This is a thousand-year-old spiritual milk that can only be condensed by a large spiritual vein.

But after tens of thousands of years, there were only seven drops of the thousand-year-old spiritual milk in the stone bowl. Chen Yuan frowned slightly, picked up the stone bowl, tilted it slightly, and poured the thousand-year-old spiritual milk into the jade bottle.

In order to prevent the spread of the black evil energy, the large spiritual veins consumed a lot of energy, and the amount of condensed Millennium Spiritual Emulsion was reduced a lot.

As soon as the thousand-year-old spiritual milk left the stone bowl, it emitted an extremely rich spiritual energy. After falling into the jade bottle, it slowly dissipated.

Chen Yuan was surprised as he looked at the inconspicuous rough stone bowl in his hand. He scanned it carefully with his spiritual sense but found nothing.
He pondered for a moment and put it into the mustard seed ring.

It will take another thousand years for a large spiritual vein to condense a drop of thousand-year spiritual milk.

By then, Chen Yuan would have either made great progress in his cultivation or turned into a pile of dirt. It would be better to take the stone bowl away. Maybe it would come in handy in the future. (End of this chapter)
