"Communication Talisman?"

Seeing the confusion on Lu Ren's face, Cao Dejing suddenly remembered: "I forgot about this matter. You just arrived at the Border City, so you wouldn't have any Communication Spirit Talismans."

Immediately, he pulled out a small card from his pocket that was neither gold nor wood, and said: "This has my communication code. You just need to activate it with Divine Thought, and you can contact me anytime if needed." 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

Seeing that Cao Dejing didn't linger, he turned around easily and quickly walked over to the Spirit Halberd that had just come out of the courtyard. She was still clad in armor, holding a long halberd, looking valiant, yet the slightly bewildered expression on her face indicated her confusion with everything before her.

Cao Dejing continued conversing with the same words, but Lu Ren was too lazy to listen further and just walked forward aimlessly.

This road was extremely wide, with an eight-lane carriageway, bustling with traffic. Above, flying boats and chariots mingled with technological flying devices, even two Exotic Beast horses galloped through the void, dragging rainbow light trails, and Sword Immortals rode their swords, their Escape Light nimble. The surrounding aura was overwhelmingly strong.

After a while, Lu Ren finally withdrew his gaze, slowly walking down the street, silently taking in everything before him. Some things he didn't even understand how they were constructed.

What surprised him was that each building was inscribed with Shielding Arrays, which seemed profound to him yet extremely common, preventing all Abnormal Power from spying.

Using Superdimensional Perception, he felt these buildings were like stubborn stones, impenetrable.

He walked until darkness fell, as the Great Sun, far larger than the star in the Current Cosmos Solar System by tens of thousands of times, set. At night, three bright moons gradually rose into the sky, and Lu Ren finally stopped.

During the span of a day, he merely wandered through a small area of the Border City. All written words here were Divine Texts, Innately formed, requiring at least the Celestial Immortal Realm to use them. Though complex, just looking at them made the meaning clear.

Understanding was one thing; when Lu Ren subconsciously tried to mimic with his fingers, he suddenly felt a terrifying force sweeping from the heavens, warning him that continuing would bring great peril upon him.

The feeling almost shattered his Physique, forcing him to stop. His expression was grave, realizing each Divine Text bore immense power, conveying vast Legal Principles.

Take, for instance, the character for fire. If written in the Current Cosmos, it could ignite an entire River System.

Despite the terror, this place was filled with these characters. He even saw small ads pasted on street corners using this script.

This Border City could suppress all such powers, preventing them from unleashing their true strength...

Lu Ren's eyes sparkled, his pupils shifting as the surrounding world rapidly transformed, stretching, shrinking, twisting, shattering, then reassembling. As his perspective elevated, Lu Ren clearly saw countless dense Array Marks filling the air, extending into every corner. At their origin, Lu Ren saw it clearly, resembling a gigantic Divine Tree towering across the starry sky, with its lush branches spreading outward.

That was the center of the Border City, the Array's center.

What shocked Lu Ren further was that this great formation fortified the surrounding space to a new height, offering a detailed perspective on the wave-particle duality application in cosmic space.

With this foundation, those ubiquitous Divine Texts shouldn't have been recorded on paper or carved on plaques, but here it became possible.

Simultaneously, the Celestial Immortal's power capable of stirring River Systems rapidly diminished here.

Lu Ren tested it; without using the Circulation Body God Fist, he struck with full force, yet the space hardly trembled, only producing a muffled sound in the air, drawing peculiar glances from several passing Female Cultivators.

Even with Lu Ren's thick skin, he blushed and quickly left the scene.

After a day of roaming, food, clothing, shelter, and transportation were all available, but Lu Ren keenly sensed the area's formidable armed forces. Over the day, over a thousand military personnel passed by him alone.

This made him realize why the city was called the Border City.

Yet, he didn't know what exactly they were battling against, given that the lowest rank required a Celestial Immortal as a soldier.

Still, he wasn't in a hurry. By staying long enough in this Border City, he would naturally come to understand.

Walking until dusk, Lu Ren paused by a closed house door on the street, looking up at the sign above.

"Armor Path!"

Lu Ren softly murmured, his gaze firmly fixed on the character 'Dao.' These three Divine Texts were distinctly different from the standard Divine Texts he had seen before, deeper and more nuanced, obviously written by someone with profound understanding of the art of Divine Texts, giving them a unique style.

What excited Lu Ren even more was that the character, written in this way, exhibited a substantial part of its Legal Principle.

"Hey, you've been standing there for almost two hours. Haven't you had enough?"

A slightly lazy voice rang from above the sign. Lu Ren snapped back to reality, somewhat reluctantly shifting his gaze upward, only to see a window on the second floor open, revealing a head that was watching him with a bit of displeasure.

It was a short-haired woman with an oval face, possessing an extremely heroic appearance. Even with just a frown, one could feel a sense of boldness, indicating her undoubtedly hearty nature.

Having concluded this in his heart, Lu Ren cupped his hands and said: "Did you write this sign, fellow Daoist?"

Noticing the appreciative tone in Lu Ren's voice, the woman's displeasure slightly faded. She muttered something, gazed at Lu Ren for a while, then suddenly spoke: "Are you new to the Border City?"

Lu Ren nodded slightly: "Indeed, just passing by, and got inadvertently absorbed by the words 'Armor Path.' I apologize."

Seeing Lu Ren's politeness, the woman couldn't stay mad. She scrutinized him for a moment and suddenly said: "You have a strong Physique, and haven't found a place to stay yet, have you?"

Lu Ren nodded: "I pursue the Body Ascension path, naturally focusing on Physique. I've made some progress in Horizontal Training."

Honestly, if not for the environment where Celestial Immortals were everywhere, Lu Ren would claim unchallenged superiority among Ultimate Celestial Immortals.

The woman showed anticipation and quickly said: "Our Armor Path needs a Blacksmith Apprentice—requirements include a very strong Physique, with preference for those pursuing the Body Ascension path. Interested?"
