Inspection Officer Zhang is approaching, and a storm is brewing in the building.

The message talisman imprinted with the star sword seal was like a giant rock cast into a calm lake, stirring up a thousand waves within Ye Yan Palace.

Patrol Envoy!

A high-ranking official of the Sky Patrol Alliance with immense authority, responsible for overseeing a region and suppressing all unstable elements. Their strength is at least Late-Stage Transformation Spirit, perhaps even Soul Transformation Perfection! What they represent is nothing less than the will of the behemoth that is the Sky Patrol Alliance!

Such a figure, actually coming in person to the Black Fiend Wasteland to "pay a visit" to the Palace Master?

The word "visit" might sound polite, but the pressure behind it is enough to make any power in the Northern Region pale. This is clearly an ultimatum before bringing charges!

Mo Yuan held the gradually dissipating talisman, his expression grave, and hurried to the outside of the Immortal Cave where Nightmare was in seclusion, respectfully reporting the situation from the outside.

Inside the Immortal Cave, Nightmare slowly opened his eyes, his gaze devoid of joy or sorrow, as if what he had heard was merely an insignificant piece of news.

"Understood."

A calm voice came from within the Immortal Cave, without the slightest ripple.

"Palace Master, that Patrol Envoy..." Mo Yuan hesitated, worried in his heart. A powerhouse at the Late-Stage Transformation Spirit or even Perfection level is by no means comparable to that green-clad guest from before.

"No matter. If he comes, let him come. Does This Sovereign need to hide from him?" Nightmare's voice remained indifferent. "Everything as usual. If he is polite, This Sovereign will talk to him. If he wants to bully others with his status..."

Nightmare paused, a trace of icy killing intent seeping into his voice: "...then let him try and see if my Ye Yan Palace is a place where he can run wild."

"Yes! This subordinate understands!" Hearing the Palace Master's calm and even domineering response, the unease in Mo Yuan's heart dissipated, replaced by a surge of hot-blooded passion. That's right, the Palace Master's Divine Ability is invincible, having even killed Soul Transformation Cultivators; why should he fear a Patrol Envoy?

After Mo Yuan retreated, he immediately gave orders for the entire Ye Yan Palace to enter a state of alert, but outwardly relaxed while inwardly tense, showing no panic, and everything was orderly.

The news spread like it had grown wings, quickly sweeping across the Black Fiend Wasteland and the surrounding areas.

"Did you hear? The Sky Patrol Alliance's Northern Region Patrol Envoy is coming in person!"

"My god! That is a truly big shot! It is said he has the cultivation of the Late-Stage Transformation Spirit! Palace Master Nightmare is in big trouble this time!"

"Not necessarily! Palace Master Nightmare is unfathomable. Didn't that Sky Patrol Alliance Elder flee in a sorry state last time? Perhaps the Patrol Envoy is just here to go through the motions?"

"Hmph, the Early Spirit Transformation Stage and Late-Stage Transformation Spirit are worlds apart! I think Ye Yan Palace is doomed this time!"

"Just wait and see, this is going to be a good show..."

Various forces discussed it, their gazes once again focused on Ye Yan Palace. Some gloated, some worried in secret, while more were watching, wanting to see how this mysteriously risen Palace Master of Ye Yan would handle this unprecedented pressure.

Profound Yin Bone Mountain.

The Xuanming Sect Master naturally received the news as well. He sat on the bone throne, his fingers tapping gently on the armrest, his eyes flashing with calculated light.

"The Patrol Envoy comes in person... Heh, good. It's perfect to use this knife from the Sky Patrol Alliance to test the depth of Ye Yan Palace. If the Palace Master of Ye Yan is suppressed or killed by the Patrol Envoy, that would be for the best. If he can actually withstand or even... then it means this person must have a massive secret or backing, and this Sect will need to plan carefully..."

For a time, the entire border area of the Northern Region was filled with undercurrents, and a storm was about to break.

Yet, Nightmare, who was at the center of the storm, remained as calm as still water inside his Immortal Cave.

Suspended before him were three things: that mass of star source core, the Jade Slip recording the Myriad Poison Demonic Scripture (Soul Transformation Chapter), and that incomplete star chart.

After breaking through to Mid-stage Dao Replenishing, his understanding of rule fragments and the star source core deepened. He took this opportunity to re-deduce and perfect the subsequent Cultivation Technique of the Myriad Poison Demonic Scripture, and better integrate it with the Law of the stars.

His Divine Sense sank into the Jade Slip, and many previously obscure and difficult parts now became clear. The rule fragment acted like the most efficient deduction hub, constantly optimizing the operation route of the Cultivation Technique and incorporating the power characteristics of the star source core.

The Demonic Essence in his body circulated according to the new route, faster and more fierce, carrying the vastness and grandeur of the stars, and its integration with his Physical Body became even tighter. The dark gold patterns on the Myriad Poison True Demon Body glowed slightly, automatically absorbing the Power of the Stars from the Void Realm, slowly strengthening.

【 Myriad Poison Demonic Scripture (Soul Transformation Chapter) optimization complete... Cultivation efficiency increased by 15%, Demonic Essence purity increased by 10%, compatibility with star source core increased to 25%... 】

【 rule fragment Fusion degree slightly increased: 8.3%... 】

The System's prompts confirmed his progress.

Subsequently, he turned his attention to that incomplete star chart. His strong Divine Sense at the Mid-stage Dao Replenishing, combined with the spatial perception ability of the rule fragment, allowed him to parse out more information from it.

"This path... seems to require crossing an extremely dangerous space storm belt... Hmm? There is a mark here, seems to be some kind of temporary rest point or transit station?"

"Fallen Star Ancient Ruins... This name seems to have been mentioned in some of the oldest Jade Slips. It is said to be an ancient battlefield where countless stars fell, incomparably dangerous, but also full of infinite opportunities..."

He carefully pondered the star chart, trying to find a safer path or more clues about the inside of the "Fallen Star Ancient Ruins". This concerned his future Dao, far more important than dealing with a Sky Patrol Alliance Patrol Envoy.

Time passed quickly in this focused cultivation and deduction.

In the blink of an eye, the Qixi Festival had passed.

On this day, at noon.

At the horizon of the Black Fiend Wasteland, the originally clear sky was suddenly rendered by a layer of faint golden brilliance.

An indescribable, vast pressure, like a tide, slowly permeated from afar to near. This pressure was not the brutality of the Demonic Path, nor the treachery of Demonic Qi, but upright, peaceful, grand, and vast, yet carrying an unquestionable supreme majesty, as if the Heavenly Dao itself had arrived to inspect the four directions!

All Cultivators on the wasteland, regardless of their cultivation level, felt their hearts tighten at this moment, involuntarily giving rise to a sense of awe, and looked up at the sky one after another.

They saw a magnificent jade carriage pulled by nine pure white, single-horned exotic beasts called "Moon-Gazing Rhinos" stepping through the air. Around the jade carriage, guards wearing silver star armor stood solemnly, their Auras all clearly at the Nascent Soul Stage! Sitting on the carriage was a middle-aged man wearing a light golden star robe, with a scholarly face but deep eyes like a sea of stars.

He did not deliberately radiate his Aura, but the vast Aura naturally flowing from him, blending with the Laws of heaven and earth, already explained everything—

Late-Stage Transformation Spirit!

The Sky Patrol Alliance Northern Region Patrol Envoy, has arrived!

The jade carriage did not seem fast, but it traveled a thousand miles in an instant, and soon arrived above the Profound Yin Ravine, stopping slowly.

A huge shadow loomed over, the vast pressure making all the Disciples of Ye Yan Palace feel difficulty breathing, their faces turning pale. If not for the Formation within the palace automatically activating to offset part of the pressure, they would likely have all knelt down already.

Mo Yuan and Su Wanqing endured the palpitations, flew out, and arrived in mid-air, bowing to the jade carriage: "Ye Yan Palace Attendants Mo Yuan (Su Wanqing), respectfully welcome the Patrol Envoy!"

On the jade carriage, the man in the golden robe swept his gaze indifferently over the Profound Yin Ravine below, paused slightly for a moment on those Formations and Restrictions, a flicker of imperceptible surprise flashing in his eyes, then looked at Mo Yuan and the other, his voice peaceful yet carrying unquestionable majesty:

"This Seat is the Sky Patrol Alliance Northern Region Patrol Envoy, Ouyang Shuo. Where is your Palace Master?"
