Immortality begins with equipping a worn-out talisman pen.

Inside the cave.

Li Mufeng sat cross-legged at the table, teasing the gold-sniffing rat in his palm.

Just now, he signed a spirit pet contract with this little guy.

It must be said that Bai's after-sales service is indeed very thoughtful; when you buy a spirit pet, you also get a spirit pet contract as a gift.

At this moment, the little one who has just been adopted is full of curiosity about his new environment.

It leaped down from Li Mufeng's palm and, like a little lord surveying his territory, sniffed around the cave.

Every now and then, it would straighten up and twitch its little nose vigorously in the air.

Its round body, paired with two big, dark eyes, makes it look adorable.

However, after circling around, it suddenly stopped.

Its small eyes darted around, then its nose twitched slightly, and it ran straight towards Li Mufeng.

The closer it got to Li Mufeng, the more its little nose twitched.

Finally, it actually crawled straight down the hem of Li Mufeng's robe and into his robe.

"squeak?"

Li Mufeng looked down, still not having reacted.

The next moment, a fluffy little head peeked out from under the clothes, holding a storage bag in its mouth.

It dragged the storage bag, which was bigger than its own body, onto the table with great effort, and then excitedly circled around the storage bag.

As it spun around, it made a soft "squeak" sound, and its fluffy tail almost became a blur as it shook.

They looked as if they had discovered a treasure mountain.

Li Mufeng couldn't help but chuckle.

This little thing has a good eye for things; it spotted the most valuable item in the entire cave at a glance.

With a thought, he took out the items from the storage bag one by one.

A mysterious black porcelain shard, several mid-grade spirit stones, a top-grade talisman brush, a mid-grade magic weapon called the Cloud-Piercing Shuttle, a Spirit-Gathering Jade Talisman...

The moment these treasures appeared, the gold-sniffing rat's eyes gleamed with golden light.

"squeak!"

It was as if it had been injected with chicken blood; the whole mouse was full of energy.

One moment they would pounce on the spirit stone to smell it, the next they would hug the talisman brush and rub it against it, they were extremely busy.

Finally, it suddenly stopped in front of that inconspicuous little black porcelain shard.

The little nose twitched slightly.

The next moment, it excitedly jumped up on the spot.

She skipped and hopped up to it, carefully holding the black porcelain shard in her arms.

Then it looked around, as if afraid someone would take it away.

He actually parted the thick, soft fur under his armpit and stuffed the small porcelain shard inside.

Then it pressed down with its two little paws.

After confirming that it was hidden properly, it patted its belly contentedly.

During this time, it even glanced warily at Li Mufeng, looking like a miser. Li Mufeng nodded slightly, thinking, "As expected of the treasure-hunting rat, it actually found the most valuable thing in this pile of treasures at a glance."

Li Mufeng reached out to try and pull the small fragment out of the golden sniffing rat's arms, but the little guy protected it like a cub, refusing to let Li Mufeng take it.

"You've gone too far! Hand it over!"

Li Mufeng laughed and scolded, then casually flicked the little guy's forehead.

The gold-sniffing rat covered its head, took two steps back in grievance, and even had a layer of mist in its big eyes.

It looked down at the small porcelain shard in its arms, then looked up at Li Mufeng.

Finally, as if resigned to his fate, he dejectedly took out the small porcelain shard.

He walked to Li Mufeng's palm, turning back every few steps.

He gently placed the small porcelain shard down, then raised his head and looked at him expectantly.

Li Mufeng, however, would not indulge it. Spirit pets should be trained well from a young age. If this little thing finds a treasure in the future and keeps it for itself, then what's the point of buying it?

Seeing that Li Mufeng remained unmoved, the Golden Rat quickly put its sadness behind it again.

It burrowed back into the pile of treasures, rummaging through them.

In the end, they chose a mid-grade spirit stone.

The little guy struggled to hug the spirit stone, then lay down on the corner of the table, sprawling out on the spirit stone.

It closed its eyes with a satisfied look on its face and even rubbed against them comfortably.

Before long, he started snoring softly.

Seeing this, Li Mufeng couldn't help but shake his head and chuckle. What a heartless little thing.

He put the treasures on the table into his storage bag, leaving only the mid-grade spirit stone for it.

Then, he turned his attention back to the small black porcelain piece in his palm and equipped it.

[Prayer Wheel (Fragment) - Gold]

[Rank: Fragment of a Magical Item]

[Effect 1: Cultivation speed +30%]

[Effect 2: Comprehension +20%]

[Effect 3: Inheritance of the Nascent Soul Chapter of the Ancient Cultivation Technique "Boundless Vast Ocean Technique"]

Now that Li Mufeng was already familiar with this method, he didn't hesitate at all and directly focused his divine sense on [Effect Three].

An ancient and melodious bell rang in my ears, and a majestic and magnificent sect slowly emerged from the long river of time.

The mountain gate stands tall, and the sacred peaks stretch endlessly.

One by one, cultivators with profound auras sat cross-legged before the scripture transmission cylinder, imprinting their life's learning into it; generation after generation of outstanding disciples received the inheritance, cultivated, rose to prominence, and finally turned into dust.

Immediately afterwards, the screen shattered.

Heaven and earth shattered, and mountains and rivers were stained with blood.

The once-powerful sect was destroyed in the great war, countless magical treasures were broken and fell, and the inheritance was scattered and eventually lost to the long years...

A massive amount of information flooded into Li Mufeng's mind like a tidal wave.

I don't know how much time has passed.

All the images vanished, leaving only an ancient and desolate cultivation manual, quietly floating above his heart.

——【The Boundless Ocean Secret】.

This is clearly a top-tier water-attribute cultivation technique that allows one to cultivate all the way to the Nascent Soul realm.

Cultivating this method will make one's dantian as vast as the sea and one's meridians as deep as a river. At the same cultivation level, one's magical power will be far superior to that of ordinary cultivators, and may even be several times greater.

What's even more mysterious is that this technique excels at protracted battles.

As the battle continues, the spiritual energy within a cultivator's body will become increasingly harmonious, and their magical power will flow endlessly. They may even be able to continuously condense their spiritual energy during the fighting, making their magical power increasingly pure.

In addition, the Boundless Ocean Technique also nourishes the physical body and slows down aging.

Cultivators who practice this method have long lifespans and abundant energy, giving them more time to hone their skills and break through bottlenecks.

As one's skill level deepens, one can gradually awaken various mysterious supernatural abilities.

In the early stages, one can use the vast water element to cleanse oneself, slowly eliminating hidden dangers such as poison, evil energy, and yin energy; when one cultivates to a higher level, one can be more inclusive of all laws and cultivate many secret techniques and supernatural powers without damaging one's foundation.

The more Li Mufeng looked, the more alarmed he became.

This is the ultimate lineage that can directly lead to the Great Dao.

Compared to that, his previous practice of the "Mysterious Water Technique" was as crude as a child's scribbles.

He even had a vague feeling.

The "Mysterious Water Technique" circulating in the cultivation world today is very likely a simplified version that evolved from the "Boundless Vast Ocean Technique" after a senior studied it, removed countless mysteries, and deteriorated over several generations.

When he eagerly began to circulate his energy according to the inherited methods, his spiritual power flowed naturally without any stagnation, like rivers flowing into the sea.

【Boundless Ocean Technique +1】

The long-awaited notification reappeared on the panel.

Li Mufeng's mind was refreshed, and he immediately sat cross-legged and immersed himself in cultivation.

Before I knew it, the night had passed.

As the first light of dawn appeared in the east, he slowly opened his eyes, his eyes filled with undisguised joy.

Perhaps because he had already mastered the "Mysterious Water Technique," his entry into the "Boundless Vast Ocean Technique" was unexpectedly smooth; he had mastered it in just one night.

However, this rapid progress did not last long.

In the latter half of the night, the rate at which the skill proficiency increased returned to its familiar slow pace, increasing by only 0.1 for each complete cycle.

Li Mufeng was not disappointed by this.

Over the years, he has become accustomed to the gradual, persistent practice of self-cultivation.

The path of cultivation is inherently a journey alongside the passage of time.

He slowly raised his hand, feeling the surging magical power within his body.

Compared to before, the total amount of spiritual power has increased dramatically. The spiritual power in his dantian is vast and continuous. In terms of sheer strength, it is comparable to that of an ordinary Qi Refining Level 8 cultivator.

To his even greater surprise, as he successfully switched cultivation techniques, his spiritual sense also grew stronger.

Just then, Li Mufeng suddenly felt something and looked up at the outside of the cave.

He got up and pushed open the door.

A pure white dove emerged from the morning mist and gently landed on the stone steps in front of the door, with a small jade tube tied to its leg.

"A message delivered by carrier pigeon?"

Li Mufeng was slightly taken aback, reached out and took the jade tube, scanning it with his divine sense.

A moment later, the expression on his face became somewhat strange.

It turned out to be a message from Chen Jingyuan.

The other party invited him to a gathering at Zuixianlou tonight. Judging from the contents of the letter, it seems that he will not be returning to Blackstone City for a long time.
