This carefree life lasted for more than a hundred years, during which she transformed from a Qi Refining cultivator into a Nascent Soul cultivator.

She initially thought the Mysterious Heaven Realm was just an exaggeration by outsiders, and not as terrifying as it seemed. Behind her master's back, she secretly entered the Mysterious Heaven Realm with her second and fourth senior brothers, believing that with their skills, even if they didn't gain much, they would definitely be able to protect themselves.

As it turned out, the dangers of the Xuan Tian Secret Realm far exceeded their expectations. There was no light source in the secret realm, the entire sky was gray and gloomy, and black winds were constantly blowing in the air.

Those black winds were filled with yin energy and evil energy, penetrating everywhere. Once the cultivator was completely permeated by these black winds, he would lose his mind, his eyes would turn red, his body would become stiff, his nails would grow wildly, becoming sharp and long, his face would turn blue, his lips would turn as red as blood, and he would become incredibly strong and have amazing defensive capabilities.

She watched helplessly as a mid-stage Nascent Soul cultivator was torn in two by a monster and then crunched and devoured.

This place is no secret realm; it's a living hell, a colossal tomb. She regretted more than once why she hadn't listened to her master, why she had been so playful, and why she had dragged her second and fourth senior brothers to such a horrible place.

They had been on the run all the way, and among those who ventured into the secret realm, more and more people were turning into those monsters. If someone was injured by one of these monsters and didn't get rid of the poison and heal their wounds in time, they would soon turn into one of those monsters themselves.

There are fewer and fewer living people around them.

Fourth Senior Brother was seriously injured while protecting her, his face as pale as a sheet of paper, but he still smiled and shook his head: "Junior Sister, you must live, or get out of here. The secret realm will reopen soon, and we will all get out of here alive."

The second senior brother's face was expressionless. There was almost no spiritual energy in the secret realm, and the only way for them to restore spiritual energy was through pills and spirit stones.

Although a lot of pills were prepared, most of them have already been used up, and Fourth Senior Brother's injuries are healing very slowly.

The second senior brother's sword has slain countless monsters. Each monster had a black crystal in its chest or heart, which should be the legendary Xuan Yin Stone, capable of nourishing the soul and promoting the cultivation of spiritual power.

The second senior brother was the strongest and most talented disciple on Heavenly Sword Peak. Along the way, he killed many monsters and fellow disciples. Those cultivators who came in with them tried to steal the spirit stones and pills from them, but they all died under the second senior brother's sword.

She had never seen so many dead people before. Gradually, she became numb, mechanically swinging her sword as if there were countless enemies in front of her.

She didn't know how long this went on, but her second senior brother always stood in front of them, even though his snow-white robes had turned gray and were mixed with countless dark brown bloodstains.

However, that figure remained standing ramrod straight.

She believed that as long as her second senior brother was there, they would definitely be able to get out alive.

She will absolutely never do such a thing again.

Unfortunately, her second senior brother, who always stood tall and straight with icy eyes and a sword gleaming white, had fallen right in front of her.

The fourth senior brother's body was half-stained red with blood, and blood kept flowing from the corner of his mouth. His two hands were still on the guqin, and the sound blades formed a protective shield to help him block the monsters that rushed at him.

"Second Senior Brother, Second Senior Brother." The Second Senior Brother's whole body was like a block of ice, and his face had become somewhat transparent, with blood constantly flowing from the corner of his mouth.

"Xiao Liu, you must live, you must survive."

"No, Second Brother, what are you going to do? I'd rather die here."

The fourth senior brother's eyes held a hint of madness: "Sixth, I'm sorry, I can't protect you anymore."

"No, Fourth Senior Brother, please stop, please stop!"

When she came to her senses, her second senior brother was enveloped in an icy blue light, making it impossible to see what was inside. She had never seen such explosive true energy before.

"No, Second Brother, if you die, I will definitely commit suicide." How could she? How could she watch her closest and dearest person die in front of her?

In the final days, the monsters went berserk, hunting down every living person. The entire black land of the secret realm was now stained crimson with blood, and the stench of blood lingered in the air.

They fought together for two days; if they could just hold on a little longer, they would be able to get out.

"Second Brother, no, Master and the others are still waiting for you."

The fourth senior brother let out a bitter laugh, snapping all the strings of his zither with both hands. Those strings transformed into giant sound blades, instantly annihilating half of the monsters.

Fourth Senior Brother also collapsed.

"Second Senior Brother, if anything happens to you, I'll self-destruct."

"Xiao Liu, you must live on." These were the last words she heard.

Before her were countless ice swords and dazzling sword lights. The intense light forced her to close her eyes, but she could still feel the power of the sword light. This was her second senior brother's Ten Thousand Swords, a magnificent display of ten thousand swords.

She had never seen it before.

Under the barrage of swords, all the monsters turned into countless ice shards and vanished into thin air.

The second senior brother's blood-red figure fell from mid-air, his black hair turned snow-white, and his whole body was ice-cold without a trace of warmth. Most terrifyingly, his life force was about to disappear.

"Second Senior Brother, Second Senior Brother."

She desperately poured all her true energy into her second senior brother's body, urging him to hold on.

"Second Senior Brother, if you can hear me, you must hold on." Her true energy was rapidly depleting, and her second senior brother showed no sign of waking up.

Even if it means death, we must protect our second senior brother's last chance at life.

And then there was the fourth senior brother. Her tears had long since dried up, and all that remained on her face was numbness and sorrow. She could never have imagined such a tragic ending, yet it was unfolding right before her eyes.

"Yes, pills, pills."

She fed all the pills to her fourth and second senior brothers. "You must, you absolutely must, survive. You must survive."

She couldn't remember what happened after that. The Mysterious Heaven Realm opened at the last moment, and all the survivors were teleported out.

She and her fourth senior brother were pulled back from the brink of death by their master's great effort, but her second senior brother burned his own bloodline, overdrawing his true essence and life. The master could only freeze him in an ice cave, hoping that the cold true energy inside could protect his body and soul.
