After Chen Ming left, Lin Xuan entered the courtyard. Three sets of clothes were neatly arranged on the bed in the room; they were the uniforms of the Sky Patrol Guard. Besides these, there was also a book, the Sky Patrol Guard Code that Chen Ming had mentioned.

Lin Xuan ignored the clothes and instead picked up the Sky Patrol Bureau's rules and began to read them.

The Sky Patrol Bureau is the core institution of the Xuanhuang Ancient Kingdom. Lin Xuan has reason to believe that if there is any major conspiracy or secret in this era, the Sky Patrol Bureau will definitely know about it.

However, with his current authority, he is certainly not qualified to know these things. He needs to familiarize himself with the rules of the Sky Patrol Bureau, then quickly promote himself to become a core member of the Sky Patrol Bureau. Only then will he be qualified and authorized to know some real secrets.

The rules weren't thick, only a few dozen pages long, and Lin Xuan quickly finished reading them. His eyes gleamed with a sharp light, and he gained a more comprehensive understanding of the Sky Patrol Division.

The Sky Patrol Division, the core institution of the Xuanhuang Ancient Kingdom, was originally established with only one sect leader.

Acting as a guardian of Heaven.

This "heaven" does not refer to the heavens and earth, but rather to the emperor of the Xuanhuang Ancient Kingdom. To put it simply, the Heavenly Patrol Division is the eyes of the Xuanhuang Emperor, patrolling the world on his behalf and suppressing the entire Xuanhuang Ancient Kingdom.

The only way to get promoted within the Sky Patrol Division is through military merit. The Sky Patrol Division patrols the heavens on behalf of the heavens, so the tasks are naturally complicated. The Sky Patrol Guards can accumulate military merit by completing tasks, and as long as they have enough military merit, they can be promoted.

At the same time, military merits were still a valuable asset within the Sky Patrol Division.

Military merits can be used to purchase elixirs, spiritual treasures, martial arts techniques, cultivation methods, and even intelligence information—all obtainable through military merits. There's even a saying within the Sky Patrol Bureau that means, as long as you have enough military merits, you can obtain anything within the Sky Patrol Bureau; there's nothing you can't exchange for within the Sky Patrol Bureau, only things you haven't thought of.

"The rules of this Sky Patrol Division are not much different from those of the Demon Suppression Division of the previous Great Zhou Dynasty."

Lin Xuan muttered to himself, "Perhaps, the Great Zhou Dynasty's Demon Suppression Division was established with the help of the Xuanhuang Ancient Kingdom's Celestial Patrol Division..."

Lin Xuan believed this was highly likely. After all, back then, the Xuanhuang Ancient Kingdom and the Eastern Wilderness were connected, so the martial artists of the Eastern Wilderness at that time should not have been as unfamiliar with the Xuanhuang Ancient Kingdom as they are now. Therefore, it was quite normal for them to imitate some things from the Xuanhuang Ancient Kingdom.

"Now, all I need to do is accumulate military merits. Only by reaching the level of a three-pattern Sky Patrol Guard can I be qualified to go to the state capital. If I can reach the level of a seven-pattern Sky Patrol Guard, I can be considered a high-ranking member of the Sky Patrol Division, or go to the headquarters of the Xuanhuang Ancient Kingdom's capital. If I reach the level of a nine-pattern Sky Patrol Guard, I'm afraid I will know all the secrets of the Sky Patrol Division."

Lin Xuan muttered to himself, "Upgrading a Sky Patrol Guard from one-pattern to two-pattern requires ten thousand military merits."

However, a single-patterned Sky Patrol Guard is not qualified to take on missions independently and can only wait for the Sky Patrol Division to assign missions.

"In that case, I'll leave a sliver of my consciousness here in the Ancient Era; my main consciousness will return to the Cosmic Era!"

One-patterned Sky Patrol Guards cannot accept missions alone; they are usually assigned group missions by the Sky Patrol Division, operating in groups or teams. Lin Xuan didn't know when the Qingyun Prefecture Sky Patrol Division would have a mission, so staying in the Ancient Era indefinitely wasn't realistic. He could leave a consciousness clone to control this body. If a mission came up, his main consciousness in the future universe would know immediately, and he could come instantly.

A thought crossed my mind.

In a short time, everything changed.

The next moment, Lin Xuanzhu's consciousness had returned to the future universe era.

The sacred land of the Big Dipper, Yaoguang Star, Xuanhuang Mountain, and the Nine Provinces Palace.

Inside the cultivation room, Lin Xuan slowly opened his eyes, his gaze gleaming. He exhaled a breath of turbid air, and an invisible pressure erupted from his body, only to be completely subdued in an instant.

"After three months, I have finally refined all the blood crystals completely, allowing my Ancient Sacred Body to advance further. My physical body has undergone a transformation, my soul has been reborn, and my strength has increased even further..."

Lin Xuan muttered to himself. He no longer needed to enter the dream world to enter the Ancient Era. He could enter directly with the help of the system and could also adjust the time flow between the two eras. So although a long time had passed in the Ancient Era, only three months had passed in the later universe era, which was just enough time for him to completely refine all the blood crystals on his body.

"call……"

After letting out a long breath, Lin Xuan had a thought, and in the next instant, he had already come out of the cultivation room and even walked out of the Nine Provinces Palace.

Standing atop Mount Xuanhuang, his eyes gleamed with divine light as he swept across the surroundings. His brows furrowed instantly, and he was filled with astonishment. Only three months had passed since he went into seclusion, yet the atmosphere on Yaoguang Star had become even more bizarre.

Calamity arose in abundance, and malevolent energy permeated the heavens and earth.

This is a sign that a great calamity is about to erupt!

"What's going on? Is it targeting the Yao Guang lineage, the entire Beidou Holy Land, or the entire cosmic era...?"

Lin Xuan's expression turned solemn. His eyes narrowed, and with a single step, he teleported out of Xuanhuang Mountain and then out of Yaoguang Star. Standing in the vast starry sky, he activated his spiritual eyes and divine gaze to their fullest extent, scanning the entire Beidou Holy Land.

Sure enough, this aura was very strange; the aura of calamity permeated the entire Beidou Holy Land and even filled the entire universe.

Although the aura of tribulation is still very thin, even his spiritual eyes wouldn't be able to detect it unless they were activated at full power. However, he could see that the aura of tribulation was increasing, and at a very rapid pace.

Moreover, he was certain that this calamity did not exist three months ago; at least, he could not see it with his spiritual eyes and divine vision at that time.

In other words, the aura of calamity had surged within these short three months, indicating a significant increase in power. This was a sign of an impending great calamity. A flash of inspiration struck him, and he subconsciously thought of the ancient powerhouses in the Blood Sea World.

Lin Xuan wasn't sure if the great calamity was caused by those ancient powerhouses, but one thing was certain: it was definitely related to them.

"The aura of impending doom is strong, something big is bound to happen. I'm afraid the next three months will not be peaceful. I should ask around."

Lin Xuan muttered to himself, and with a thought, his body transformed into a streak of light, streaking across the sky and returning to Yao Guang Star, the sacred land of the Big Dipper. Then, with a thought, he immediately used a communication talisman to send a message to Yan Ping, Xu Ning Shuang, and Li Ji Feng.

He didn't know many people in this sacred land of the Big Dipper, and he was only close to Yan Ping and the other two.

One hour later.

Yan Ping and the other two arrived simultaneously, flying into Xuanhuang Mountain.

Lin Xuan was already waiting at the main entrance of the Nine Provinces Palace. When he saw Yan Ping and the other two arrive, he immediately greeted them with a smile.

"Junior Brother Lin, you've finally emerged from seclusion..."

Yan Ping was the first to smile and say to Lin Xuan, "You have no idea what has happened in these three months."

"oh……"

Lin Xuan's eyes narrowed, a sharp glint in them. Just as he had predicted, the entire universe had likely been in turmoil for the past three months. However, he didn't rush to ask what had happened. Instead, he cupped his hands in greeting to Yan Ping and the other two, saying, "Senior brothers and sisters, let's go inside the hall to discuss this!"
