At the age of one hundred, I inquired about the Dao, awakening the supreme spiritual root that shatt

As Lin Mo spoke, he couldn't wait to take out his exquisite wooden box, inside which three cloud grasses emitted a clear and cool medicinal fragrance.

This strange herb is less than the size of a palm, completely white, without roots or leaves, and shaped like a cloud or a transparent mushroom.

As the faint fragrance entered his nostrils, Ling Xiu felt as if his soul had been cleansed and purified, his mind clear, and his whole body feeling incredibly comfortable.

It was the cloud grass he had been searching for that was the most essential ingredient in refining the Tongxuan Pill.

"I've finally fulfilled my mission!"

Su Hui was weak and her once beautiful face now bore a hideous bloodstain, making it clear at a glance that the two of them had paid a heavy price for their trip.

Upon closer inspection, all three herbs were over six hundred years old.

Overjoyed, Ling Xiu stepped forward, opened his arms, and embraced Lin Mo tightly.

"Brother Lin, from now on we are close friends. You two have truly worked hard this time!"

Looking at the delighted Ling Xiu, Su Hui still felt lingering fear when she recalled the terrifying monsters at the bottom of the abyss.

"Brother Li, the beast guarding the depths of that Black Abyss is a Blood-Eyed Demonic Ape, a Rank 1 Earth-level demonic beast. It is ferocious and most adept at attacking the souls of cultivators. We have nearly perished under its claws several times, and every step we take is fraught with danger."

After saying that, a look of relief appeared on her face.

"Fortunately, the trip was very fruitful."

Recalling the scene of the battle, the two still feel lingering fear.

The Blood-Eyed Demon Ape is far more ferocious than ordinary demonic beasts, and its combat power is comparable to that of other ferocious beasts of the same level.

Ling Xiu's smile slowly faded. Knowing that the two of them had a near-death experience, he immediately decided to fulfill all his promises.

"Since Brother Lin and his wife trust me so much and are willing to risk their lives, I will never break my promise."

These are six Spirit Fusion Pills that I prepared in advance. In addition, I previously promised to refine any pills you need; please ask at any time.

After saying that, Ling Xiu summoned 100,000 low-grade spirit stones from his Qiankun Ring.

"Please accept this small gift."

He handed the spirit stone directly to Lin Mo.

"One hundred thousand spirit stones?"

Lin Mo did not refuse, and his admiration for Ling Xiu's character grew stronger.

The other party, being an alchemist, was not short of spirit stones, yet still kept his promise. This unexpected windfall made the adventure all the more worthwhile.

Su Hui tried to persuade her from the side.

"Please accept it. Fellow Daoist Li is a very generous person. If we refuse, he will feel uneasy."

The three exchanged a smile, all their misunderstandings vanished, and they addressed each other as friends.

The two took out the prepared auxiliary materials and told Ling Xiu that he still needed to refine a few Soul Cleansing Pills.

"The Soul Cleansing Pill is not difficult to make. I will immediately heat up the furnace and refine it for you two."

Three days later, five mid-grade Xuan-level Soul Cleansing Pills were produced. Lin Mo and his wife were filled with gratitude and their respect for Ling Xiu deepened.

A mid-stage Nascent Soul alchemist is already at the Spirit Rank level and is respected wherever they go.

Ling Xiu felt quite comfortable having this couple as his neighbors.

With the Cloud Grass, Three-Tailed Wind Leaf, and Separated Earth Fruit—the three core ingredients—all gathered, the time to refine the Profound Mystery Pill has finally arrived.

However, the Tongxuan Pill is an Earth-rank spiritual pill, and its refining difficulty far surpasses that of all other spiritual-rank pills.

If the furnace explodes or there is even the slightest mistake during the alchemy process, all the medicinal herbs will be ruined.

Therefore, not only do you need top-grade auxiliary materials, but you also need to have a deep enough level of alchemy cultivation to increase the probability of successful pill formation.

He did not rush to start refining, but repeatedly studied the "Mysterious Origin Creation Elixir Canon", devoted himself to studying every step of the process, and constantly deduced the complete refining process in his mind, striving to control every detail.

With his current alchemy skills, he has only a 70% chance of successfully refining the Tongxuan Pill.

"Now my true essence is abundant, my divine sense has a wide range of exploration, my physical body is incomparably strong, and my cultivation has reached the peak of the Great Perfection of the True Essence Realm. Everything is ready!"

During this period, his alchemy skills steadily improved, reaching a level of perfection. He successively refined multiple batches of spirit-grade pills, firmly establishing himself as a mid-stage spirit-grade alchemist.

"Thirty years have passed in the blink of an eye. I, a centenarian, have undergone a tremendous transformation in my physical body, soul, and cultivation."

Ling Xiu sighed inwardly.

Now he can finally refine the Tongxuan Pill and use it to break through to the Tongxuan Realm.

His physical body, soul, true essence, and alchemy were all at their peak.

Let's begin!

He had already refined many batches of Xuan-level spiritual pills, laying a solid foundation.

Today happens to be my birthday, which is considered a rare auspicious sign. The three cloud herbs represent three opportunities to refine elixirs.

Ling Xiu neatly arranged the Three-Tailed Wind Leaf, Cloud Grass, and Separation Earth Fruit on the alchemy table, then cleansed himself, took a bath, and changed into a brand-new alchemy robe.

The alchemy furnace used this time is a brand new ancient alchemy furnace in excellent condition. The furnace body is carved with birds, beasts, stars and clouds, and is dark gold all over. It is solid and can greatly reduce the probability of the furnace exploding.

The furnace lid radiates a restrained spiritual light and is surrounded by precious aura, its grade far exceeding that of ordinary alchemy furnaces; it is a superior spiritual artifact alchemy furnace.

His Qiankun Xuanhu has long been tempered and upgraded into a top-grade pill furnace. Even when refining top-grade Xuan-level spiritual pills, the furnace will never explode. It can completely withstand the violent medicinal power impact of the Tongxuan pill.

The fragrance of the spiritual herbs filled the quiet room. Ling Xiu took a deep breath, focused his mind, and concentrated all his attention on the three spiritual herbs.

The earth's heat is activated, the furnace is warmed and the fire is adjusted, and the medicines are added in the order recorded in the alchemical texts. The mixture is then quenched over a gentle fire to solidify the elixir base.

As a Rank 1 Earth- elixir, the Tongxuan Pill is fraught with peril in its refining process. The three spiritual herbs each contain two diametrically opposed forces: extreme yin and cold, and pure yang. During the fusion and tempering process, they constantly collide, causing the soul to tremble.

The immense medicinal power caused the alchemy furnace to vibrate and hum incessantly. Ling Xiu used his divine sense to precisely detect and control the heat at all times, continuously infusing it with longevity essence. Every step of the operation was extremely rigorous.

Three Cloud Grasses correspond to three refining opportunities, allowing no room for error.

The first attempt at refining the medicine failed at the stage of merging the medicinal power. The earth flames fluctuated slightly, and the balance of yin and yang medicinal power collapsed instantly.

boom!

A burnt smell billowed out of the furnace, and the most fire-sensitive of the three main herbs was burned to ashes.

Ling Xiu dared not delay, quickly cleared the residue from the furnace, and put in the second cloud grass to start refining again.

This time he was extra cautious, but the refining cycle of the Three-Tailed Wind Leaf and the Separated Earth Fruit was extremely long, and the consumption of divine sense over a long period of time meant that the second batch still failed.

"No, the spiritual energy is being severely depleted; the cultivation method must be adjusted!"

Although this batch of spiritual herbs did not completely turn to ashes, it condensed into a considerable amount of pure spiritual liquid, which can be considered a turning point. It is only one last step away from forming the pill.

After two failures, only one cloud grass remained, and the medicinal power of the two main ingredients in the furnace was also reduced by more than half.

Ling Xiu sat cross-legged and regulated his breathing for seven days, calming his mind and nourishing his spirit. He reviewed the oversights of his previous two failures again and again, and repeatedly rehearsed the entire process of refining the medicine in his mind.

After a long while, he suddenly opened his eyes, his gaze gleaming, and he already had a perfect plan in mind.

Calm his mind, remain humble and composed, and get up to prepare for the third refining.

This is the last chance; you must succeed!

Open the furnace!

He put the last cloud grass into the furnace and started the tempering process again.
