Cultivation of immortality begins with an eighty-year-old eunuch.

"call……"

Chen Fan slowly opened his eyes and exhaled a long breath of dark red turbid air.

The turbid air condensed in the air and did not dissipate. After churning for a while, it gradually turned into nothingness.

He clenched his fist slightly, and his knuckles made a series of popping sounds like popping beans. The surrounding space even rippled slightly because of this pure physical strength.

"Early stage of Core Formation..."

Chen Fan felt the surging, ocean-like power of his bloodline within him and murmured to himself.

After ten years of arduous cultivation, he managed to push his body, which originally belonged to the lower third grade of aptitude, to the early stage of Core Formation by relying on his improved blood tempering method.

Now, his physical strength is absolutely comparable to that of the clan leader, Iron Bone.

Even in terms of the purity of his bloodline power, his "upper-level three" bloodline is extremely stable, and there is even a faint tendency for it to transform into a higher level.

However, Chen Fan was not concerned about cultivation level.

He immersed his consciousness into his mind, looking at the test boundary that still showed little movement, and frowned slightly.

"Ten years have passed, and is the sense of belonging still only so faint?"

Chen Fan muttered to himself.

Over the past decade, he has integrated into this tribe, watched those ancient demon children grow up, watched the old miners die, and watched the warriors laugh around the campfire and bleed on the battlefield.

He also prescribed medicine to regulate the blood and qi of newly born little demons, and he also saw off the deceased elderly members of his clan.

Subconsciously, he did develop a sense of identification with this seemingly brutal yet strangely tender race.

He no longer viewed them with the indifferent perspective of a mere bystander, as he had initially done.

But this is not enough.

This slight sense of recognition is nothing more than a drop in the ocean when it comes to getting past this "demon heart" test.

"Forget it, you can't force someone to agree with you."

Chen Fan shook his head, a gentle smile appearing on his lips. "Since there's no rush, let's just continue living like this. This life... is passable."

After ten years of reflection, his mindset has become extremely peaceful, and he is no longer anxious about the challenges ahead.

For him, practicing medicine, treating illnesses, and cultivating himself here is a rare form of quiet retreat.

"Uncle! Uncle!"

A crisp, slightly stiff shout came from afar.

Chen Fan looked in the direction of the sound and saw a little ancient demon, about seven or eight years old, running towards them.

This little ancient demon is called Shi Dou, the child of Shi Chi, the miner who suffered a leg injury years ago. Chen Fan accepted the thank-you gift from Shi Chi and his wife back then, and thereafter had more dealings with the family.

Now that the child has grown up, he has a head of red hair and two small, fuzzy, curved horns on his forehead, which makes him look rather adorable.

Why are you running so fast? Be careful not to fall.

Chen Fan stood up and looked at Shi Dou gently.

Shidou ran to the big rock, put his hands on his knees, and gasped for breath. His little face was red from the strenuous exercise.

"Uncle... my father, my father sent me to call you." Shi Dou finally caught his breath and pointed towards the center of the tribe. "Chief, the chief is waiting for you in the council hall. He said he has something important to discuss."

"event?"

Chen Fan raised an eyebrow slightly.

Over the past decade, although the Black Rock Tribe has expanded considerably, most major matters are resolved internally by the soldiers and the elders, and Iron Bone rarely disturbs his secluded cultivation.

Why are you sending someone to invite me in such a hurry? Could it be that you've encountered some trouble that even Tiegu can't solve?

"Do you know what it is?" Chen Fan asked.

Shi Dou shook his head, his pair of red, curved horns swaying: "I don't know, but I saw the chieftain wearing his most magnificent set of bone armor, and he even saddled the tribe's few remaining 'Iron Horned Beasts,' as if he were about to embark on a long journey."

"Going on a long trip?"

Chen Fan pondered for a moment, then patted Shi Dou's head: "Alright, I understand. You go back first, I'll pack up and head over."

"Alright! Hurry up, uncle!"

Shi Dou responded crisply, then turned and ran away like a gust of wind.

Chen Fan returned to the stone house, tidied his clothes, and took a few bottles of commonly used medicine powder and a newly sharpened bone sword before heading towards the council hall in the center of the tribe.

As he walked along the tribe's stone-paved road, the tribespeople he encountered all bowed to him.

"Good morning, Pharmacist." A burly ancient demon who was carrying ore stopped and greeted him with a somewhat simple and honest smile.

"Pharmacist, my husband was able to get out of bed and work yesterday after taking the medicine you prescribed. Thank you so much!" Another ancient demon woman called out from afar as she washed clothes by the ditch.

Chen Fan smiled and nodded in response to each question, his demeanor gentle and without any airs of a powerful figure.

Upon arriving at the entrance of the council hall, several heavy carts pulled by giant unicorns were already parked there.

The vehicle was piled high with boxes of all sizes, some of which even had the faint glow of spirit stones seeping through the gaps, clearly the most precious possessions accumulated by the Black Rock Tribe over the years.

Tiegu was standing next to a cart, directing several soldiers to move goods.

Ten years have passed, and Tie Gu looks even more robust than before, but also bears the marks of time. His bone armor is polished to a gleaming shine; it is ceremonial armor worn only during tribal rituals.

"Chieftain, are you going to empty out all your possessions?"

Chen Fan stepped forward and made a casual joke.

Tie Gu turned his head and saw Chen Fan. A bitter smile appeared on his somewhat stern face.

He hurried forward, sighed, and said, "Pharmacist, you've finally arrived. This time, I'm taking you to the 'Skyfire Tribe'."

"Skyfire Tribe?"

Chen Fan's brows twitched slightly.

Over the past decade, although he has paid little attention to the outside world, he has gained a general understanding of the power structure of this planet through his interactions with Mugu and others.

This ancient demon star is extremely vast, with countless wastelands, on which thousands upon thousands of ancient demon tribes are scattered.

Above these tribes, controlling the order of the entire planet, are several super tribes with ancient heritage.

The Tianhuo tribe is the strongest and most profound among them.

It is said that the holy city of the Tianhuo tribe is located on a volcano that has never burned for thousands of years. The tribe not only has ancient demon priests in the Nascent Soul stage, but also an ancient demon ancestor in the Divine Transformation stage.

Compared to the Skyfire Tribe, the Blackrock Tribe is now nothing more than an infant just learning to walk.

"What are you going to the Heavenly Fire Department for?" Chen Fan asked.

Tie Gu pulled Chen Fan to a secluded spot and lowered his voice, saying, "Rules. The ironclad rules of the Ancient Demon Clan."

He paused, his tone tinged with helplessness and self-deprecation: "Over the past ten years, our Black Rock tribe has swallowed up several smaller tribes in the vicinity, leaving only our voice for thousands of miles around. In this area, we are the boss. But according to the rules above, any tribe that unifies the surrounding region must go to a larger tribe to show submission, offer tribute, and register their territory. Otherwise..."
