An emperor in his later years is summoned by his sister to save the nation's fate.

Dragon Kingdom, Tianhai City, 749 Bureau Branch, Awakening Room.

Intern investigator Lu Xueyao was standing alone in the center of the room with her back to the door.

Three years ago, Earth was subjected to a bizarre and comprehensive invasion, rendering its firearms ineffective and plunging humanity into dire straits.

To combat the supernatural, the Dragon Kingdom quickly established Bureau 749 and, through constant sacrifices, discovered the only way to fight back—the Ghost Keepers.

Those with strong willpower may awaken their destined supernatural pet when facing bizarre events, thus gaining control of supernatural power to deal with the strange occurrences.

Lu Xueyao was originally a freshman in college. Three years ago, her brother Lu Li, who depended on her for survival, mysteriously disappeared when something strange happened.

In order to find her brother, she resolutely joined Bureau 749 and, after three years of training, finally arrived at today's awakening ceremony.

She wore a specially made black tactical uniform, which accentuated her tall figure and graceful curves.

Lu Xueyao was stunningly beautiful, with a neat ponytail, but her temperament was as cold as ice, her eyes fixed on the white wall in front of her.

Not far behind her, there was an open golden containment box.

A blurry gray mist was constantly moving behind her.

It is indeed a Class D Mystery—the Screaming Mystery.

Its killing rules are simple: call its name, and if it turns around, it will die. To awaken a strange pet, one must endure the eerie calls and never turn around.

The longer you persist, the greater the probability of awakening. On the other side of the safety glass, several figures are watching the scene.

Ten people participated in the awakening in this batch, but now only Lu Xueyao is still persisting.

Seven people were eliminated due to mental breakdowns, and only two succeeded.

One of them is Liu Mengxi, hailed as a genius investigator.

She looked arrogant. Not long ago, she successfully awakened the purple-quality pet, Chu Renmei.

The other person is Zhou Yang, who has awakened a blue-quality painted skin. He is slightly less talented and is also Liu Mengxi's suitor. He is standing next to her at this moment.

"Lu Xueyao is quite resilient," Zhou Yang remarked, observing the scene.

Liu Mengxi snorted coldly, a hint of jealousy flashing in her eyes.

She had always disliked Lu Xueyao's kind of beauty—a natural beauty that could steal everyone's attention.

"What's the point of enduring it for so long? If you can't awaken, you're still just an ordinary person."

Standing in front of the two was Qin Chuan, the official investigator for this assessment.

Qin Chuan, a C-level Ghost Master, stared intently at the data panel, his face filled with anticipation.

In case of any unforeseen circumstances, he could forcibly sever the supernatural connection and suppress this Class D anomaly.

"I've held on for five minutes now," Qin Chuan thought to himself.

Being able to survive for five minutes under the rules of killing means that Lu Xueyao has a high probability of awakening a powerful ghost pet.

Inside the awakening room, a chilling, bone-chilling atmosphere constantly assaulted Lu Xueyao's senses.

The gray mist emitted various sharp sounds, constantly calling her name.

She clenched her fists so tightly that her nails dug into her palms, forcing herself to stay awake.

Just then, the tone of the voice calling out suddenly changed.

The piercing ghostly sound disappeared, replaced by a gentle and helpless male voice.

"Xue Yao..."

Upon hearing that sound, Lu Xueyao's body trembled violently.

This is the voice of her brother, Lu Li, who has been missing for three years!

"Xueyao, brother is so cold, turn around and look at me..."

The voice was filled with painful pleas, as if the ghost had invaded her subconscious through supernatural powers, perfectly mimicking Lu Li's voice.

……

Meanwhile, in the Xuan Tian Realm, in the forbidden zone of life, at the Undying Mountain.

Above the endless black dead mountains, the sky cracked open, and black mist intertwined.

A tall figure clad in black stood in the void.

His face looked somewhat aged, his white hair danced wildly in the wind, his vital energy was almost depleted, and the flame of his life was like a candle flickering in the wind.

However, his body was surrounded by overwhelming demonic energy, with faint signs of stars being born and dying, causing the space to collapse continuously.

He was Lu Li, who had been missing on Blue Star for three years. Three years on Blue Star, but ten thousand years had passed in the Xuan Tian Realm.

He is now the Great Emperor of the Human Race, known as the Eternal Night Demon Emperor.

However, he is now old and suffering from Daoist injuries, and is about to pass away. Today, he ventured into the forbidden area alone, only to seek an elixir of immortality so that he could live a second life.

"boom!"

Deep within the Undying Mountain, three auras soared into the sky, revealing three dormant supreme beings from forbidden zones.

A colossal phantom coldly sneered, "Eternal Night, your life force is exhausted. You dare to venture into the Undying Mountain alone?"

Another supreme being covered in red hair sneered, "You have been an emperor for thousands of years, yet you are still only a third-level emperor, the weakest emperor in history."

Do you also wish to emulate the sages of the past and pacify the forbidden zones of life? Why not follow our example, sever your own flesh, become a member of the forbidden zone, and devour the essence of all living beings to prolong your life!

Lu Li's eyes were icy cold; to live by severing his own life was definitely not what he wanted.

Just as the remaining imperial blood within him was boiling, preparing to unleash his imperial weapon for a life-or-death battle against these three supreme beings.

A faint yet familiar voice suddenly rang in his ears.

"elder brother……"

Lu Li suddenly stopped, his eyes filled with disbelief.

This is the voice of his blood relative, his younger sister Lu Xueyao!

He has been gone for ten thousand years. Even if the planet Earth has not been destroyed, his sister should have been reincarnated a hundred times by now. How can he still hear her voice?

Just as he was in shock, a mechanical voice sounded in his mind.

[Ding, congratulations host, you have awakened the Guardian System.]

[The current automatically bound guardian is the host's younger sister, Lu Xueyao.]

[System rules state that as long as you successfully protect Lu Xueyao, you will receive a protection reward for each successful protection.]

[It has been detected that the host and Lu Xueyao are not in the same plane. In order to ensure the smooth progress of the protection, a wisp of the host's will can be projected to Lu Xueyao's side.]

The projection strength depends on Lu Xueyao's cultivation level. Currently, Lu Xueyao is a mortal, and the projection power is only one trillionth of the host's strength. To ensure the host's protection, the time flow between the two realms has been permanently adjusted to 10:1, meaning 10 days in the Xuan Tian Realm are equal to 1 day in the Blue Star Universe.

[Do you want to confirm that you want to turn on the projector?]

Lu Li's eyes flickered. He had cultivated diligently for ten thousand years, relying entirely on his own efforts. He never expected that he would receive a cheat code as he was about to pass away. Moreover, judging from the system's words, it seemed that not too much time had passed on Blue Star.

"confirm."

Without any hesitation, Lu Li silently recited it in his mind.

Meanwhile, in the Awakening Room of Bureau 749 in Tianhai City, Dragon Kingdom, on Blue Star.

Upon hearing the desperate cry, Lu Xueyao's emotions ultimately triumphed over her reason.

Her eyes were red-rimmed, and she turned her head away.

Turning back means certain death; the killing pattern has been triggered!

In an instant, the gray mist emitted a piercing shriek, transforming into a vast expanse of chilling fog that swept out, its outline unfolding as it was about to completely engulf Lu Xueyao.

Outside the safety glass, a hint of regret flashed in Qin Chuan's eyes.

Lu Xueyao was just one step away from awakening, but if she turned back on her own initiative, it would mean the supernatural connection would be severed, and she would have no chance to awaken her supernatural pet.

He sighed, and supernatural power surged within him, preparing to suppress the ghost that was calling out to people and save Lu Xueyao.

Meanwhile, Liu Mengxi stood to the side with an arrogant expression, secretly pleased with herself.

If Lu Xueyao fails, she will only be relegated to a clerical position with no combat power, and will no longer be qualified to be compared with her.

However, just as Qin Chuan was about to make his move...

hum!

Without warning, the void behind Lu Xueyao rippled like water.

A phantom of an old man in black appeared out of thin air. He had a full head of white hair and an old face, but his posture was as upright as a pine tree.

Although it was just a phantom, the gaze of this projected image conveyed a terrifying sense of looking down upon all living beings and suppressing all ages.
