Omens of Tribulation 

As soon as they entered the invisible spirits realm, it was as if they had moved to a completely different realm, where the landscape around them changed dazzlingly. A wide area stretched in front of them, towering mountains rose on the horizon, enveloped in light and soft clouds, reflecting the golden rays of the star on their peaks. 

These mountains seemed like silent guardians of the hidden realm, keeping its deep secrets within their dark caves. Between the mountains, green valleys descended, with pristine streams flowing.

Caves have spread throughout the realm, some open and revealing dark depths, while others hide hidden entrances between rocks and climbing plants. 

Among the wild nature, ancient buildings have emerged scattered around the realm, dating back to different eras. These buildings had unique architectural designs, reflecting diverse civilizations. Some were ruins of ancient towers, which found their way high, while there were temples decorated with spiritual patterns, telling stories of ancient rituals and forgotten gods.

The sky above them was dark and strewn with thin white clouds. As time passed, there was a star casting a golden shadow on Earth, before they were greeted by the night sky with its twinkling stars telling stories from time immemorial. It was like they entered into a dream rather than a world that only God knew how long he was here.

"Well, remember very well what was said in the sect, we only have forty days and the invisible spirits realm will close again. Do not rush to search for treasures, and let destiny take you in your search. Also, don't stray too far from our group," said master Qing Shan, looking at the surprised disciples and telling them firmly and in a cautious tone.

The disciples stood around her, ranging in age from young people to experience, with their eyes full of questions and anticipation. They knew that entering the invisible spirits realm was a seldom repeated opportunity, as each of them could have enough experience and gains to come back stronger. 

When she finished speaking, master Qing Shan pulled out an old sniffing scroll from her storage bag, but it was radiating with mysterious and curious vitality. She raised her hand with a majestic move and carefully removed the seals and restrictions that surrounded it, sounding the grunts of admiration among the disciples.

This scroll was known as the "Heavenly Spirit Scroll". For each sect, such as the eternal spirit sect, there was its own version of this scroll, and it is considered one of its most precious and valuable treasures. It was not just a map, it was the result of the efforts of former masters, who roamed this invisible realm and carefully transcribed the sites of precious treasures and rare herbs.

"Let's go," said master Qing Shan with a sigh as she led the disciples to the first place in the heavenly spirit scroll and near them, watching carefully and looking at Zhao Yongchen.

Zhao Yongzheng, on the other hand, was walking with his older sister leisurely, looking around with wonder as well, and said curiously, "I didn't really expect it to be that big."

"Me too, oh, what is this?" As they walked, Zhao Xiaohui noticed a strange herb from afar as she walked, and certainly she wasn't the only one who noticed this.

The plant shimmered with a silver-blue color, radiating a mysterious aura that attracted attention from all directions. Its green leaves resembled shiny crystal flakes, while its tiny flower resembled a pearl shining in sunlight, beating with a radiance that attracted the eye and captivated the heart.

What made the plant more distinctive was the sweet smell that smelled of it, as it mixed lavender perfume with wildflowers, which made the students rally around it in amazement, as if it were a hidden treasure in the midst of wild nature.

Zhao Xiaohui stopped for a moment, then she said with surprise, recalling where she had seen the description and shape of this plant before, "This is not an ordinary plant. It is a heavenly ether plant, said to have strong therapeutic properties, and used in making many powerful potions."

Zhao Yongzheng smiled as he looked at his big sister: "My big sister is really smart, you knew it from just a few quick glances, come on get it"

When she was about to go quickly to get it, there was another figure who went to pick it up quickly before someone else went to it, the first disciple of the Phoenix Hall, Jing Yi, said with an arrogant laugh "Hehe, we just entered and I got the heavenly ether plant, the invisible spirits realm was not really just a name." 

Everyone watched with apparent interest as Jing Yi got the heavenly ether plant, which shone like a piece of candy falling into her hands. The disciples were jealous and dissatisfied that they had not acted early, and some whispers began to creep in. However, master Qing Shan intervened quickly to calm them down, saying in a firm and reassuring voice:

"Don't worry, there are a lot of treasures in this place, and each of you will find something valuable. Good job, Jing Yi, the heavenly ether plant will be of great benefit to you in your cultivation. And you, too, Zhao Xiaohui, have shown great skill in identifying it quickly."

As master Qing Shan spoke, Zhao Xiaohui looked resentfully at Jing Yi, and remembered how she could have reached the plant first if she had acted faster. She whispered to herself angrily: "That bastard!"

Zhao Yongzheng saw his older sister's expressions, so he tried to console her with a warm smile and said, "Don't worry, I believe you'll find something better soon."

The group continued within this magical realm, as each turn held the potential for a new discovery. Some found grasses as good as, but not rare as, heavenly ether, while others found raw materials that could later be converted into powerful spiritual weapons. 

Zhao Xiaohui walked with determination, and her eyes shined with clear determination. Soon, the treasures began to unfold one after another. Whenever she found a new treasure, she would proudly smile at her brother and display it proudly, saying, "Look, Zhao Yongzheng, I seem to be starting to find my share of luck too."

The treasures Zhao Xiaohui found were no less impressive. There was an amazing jewel that shimmered in rainbow colors, and a number of rare herbs that were unnoticed by the eyes of others. 

As the group continued to explore this world full of secrets, Zhao Yongzheng's expression became a little serious, but went unnoticed by others as they indulged in discovering the treasures around them. There was something that drew Zhao Yongzheng away from the other things around him.

Zhao Yongzheng kept a special secret that was unique to him from the rest, and it is one of the main reasons he came to the invisible spirits realm: his extreme sensitivity to the life energy and spirit that emanates from all objects and bodies around him. 

Because the spiritual sphere absorbed its spiritual power, Zhao Yongzheng has become very sensitive to spiritual power, so that he can distinguish rare and powerful things from merely releasing life energy from them. This made him superior to other cultivators, and allowed him to discover treasures so easily that no one else could.

He looked around carefully, making sure no one was paying attention to him, and slowly moved towards a field of flowers. Master Qing Shan watched him carefully, but when she found him heading towards a seemingly normal flower field, she did not catch on to anything, thinking that Zhao Yongzheng might be looking for something different or trying his luck. 

Zhao Yongzheng came closer to the flower field until it was near a certain flower. At first sight, this flower seemed normal, but Zhao Yongzheng felt an energy release that he had never felt before. The flower glowed in a smooth, blackish color.

He carefully reached out to the flower, where he noticed that the leaves wrapped in a magnificent spiral around it, shining with tiny starlike dots on a clear night. That flower was beating with a strong and unique life energy, Zhao Yongzheng felt that this flower was not just an ordinary plant, but did not know what it was. 

Zhao Yongzheng leaned cautiously, touched the flower gently and said with a smile: "Hey, good harvest."

This was one of his goals in entering the invisible spirits realm: complete spiritual sphere. He knew that collecting high life energy would help him achieve that goal, so he desperately wanted to collect as many of these treasures as possible before he left this realm.

Outside the invisible spirits realm, in eternal spirit sect. 

Dark clouds loomed on the horizon, covering the sect in a sweeping darkness that prevented any small ray of the sun from passing through. It was not only this darkness that caused concern in the souls, but the sounds of thunder and lightning that permeated it, which made everyone's hearts jump in their chests, undoubtedly telling them what would happen next.

It was similar to what happened thirty-three years ago, when the sinful heavenly tribulation occurred, a mythical tribulation that represents a serious test for the sinful son, as they have to face the supernatural forces of nature to survive and advance on their spiritual paths. 

The sec master, Zhao Jian, stood in the center of the sect's main square, surrounded by his disciples and the sect's top leaders. He looked up at the dark sky hovering over him, his eyes glistening faint. "The most terrifying thing about the heaven is ability to predict,"
