Around seven o'clock in the evening, a milky-white elemental portal opened in the courtyard. From the portal emerged a man and a woman, both dressed in seamless celestial robes, with light blue long hair and an aura of harmonious elemental energy surrounding them. Xiao Jie, who was about to head home, walked out of the house and bumped into the two newcomers. The girl who stepped out first saw Xiao Jie and excitedly rushed forward, grabbing his hand and looking at him with deep emotion. "Are you alright? Since I left, I haven't heard from you. Master Yuandun told me you had returned, so I came specifically to see you."

"Fuer Li, it's you. What brings you here?" Xiao Jie was equally excited. This woman shared a special bond with him, having spent a night together as husband and wife.

Fuer Li responded, "Actually, my visit is arranged by Master Yuandun. Before you went to ancient times, the master should have told you to see the truth and come back alive. The master, who rarely involves himself in worldly affairs, informed us about everything. I came this time to tell you some secrets. We might become comrades-in-arms in the future." As she spoke, Fuer Li leaned closer to Xiao Jie, clearly showing that she had deep feelings for him. She was not as carefree as when she left Laoshan; after all, she was a woman who needed someone to rely on.

Their moment was interrupted by an untimely cough. Master Wang and the others had already arrived in the courtyard, and they couldn't miss the elemental energy radiating from such a close distance. The usually calm Yue Nan'nan stepped forward, pointing at Fuer Li and her companion, questioning them sharply, "Who are you? What are you doing here?" Her eyes also glanced at Xiao Jie with suspicion.

Under Yue Nan'nan's sudden questioning, Xiao Jie instinctively let go of Fuer Li's hand and said nervously, "This is Fuer Li from the fifth dimension. What's wrong with you?"

Realizing her lapse, Yue Nan'nan quickly composed herself. Master Wang stepped in to smooth things over, "Actually, they're old acquaintances; it's just that some of you haven't met before. Let's talk inside."

Led by Master Wang, everyone returned to the house, and the earlier awkwardness gradually dissipated as they discussed serious matters. After brief introductions and pleasantries, Fuer Li got straight to the point. "We came to inform you of a significant matter. Our people from the fifth dimension have long foreseen an impending catastrophe. This was later confirmed by Master Yuandun, validating our predictions."

Under the expectant gaze of the group, Fuer Li recounted the facts shared by Master Yuandun with her and her companions in Laoshan. She explained that in the course of history, a species extinction cycle occurs every ten thousand years, leading to the emergence of new species. Examples of such cycles are numerous in the historical records held by the true fifth-dimensional beings. For instance, ancient manuscripts from the Vatican mention that Earth had four human generations. The first generation was giants, who perished from hunger. The second generation was destroyed by massive fires. The third generation, the apes, annihilated themselves through mutual slaughter. The fourth generation, the 'Sun and Water' phase humans, were decimated by a great flood. However, not all humans perished in these cataclysms; some wise individuals evolved into fifth-dimensional beings. Chinese people, notably, are descendants of the fourth generation who survived the flood due to the success of their mission. Yet, whether by fate or cyclical destiny, today's humanity faces an unprecedented catastrophe ten thousand years later. This generation of mission bearers will confront the invasion of three great demon kings.

Hearing this, Professor Wang asked, "Three great demon kings? Are there others besides Lucifer mentioned in the scriptures?"

Fuer Li gravely replied, "Yes, the bloodthirsty war god Chiyou will return with greater power. Moreover, a powerful alien species from the outer reaches of the Milky Way, from the planet Morgada, will invade Earth. These beings, born with the power of fifth-dimensional people, lack the immortality of true fifth-dimensional beings but possess parasitic abilities. They can find hosts and parasitize them, absorbing their life force to renew their own lives. Thus, they are known as cosmic marauders, a warlike and powerful race."

The story has been stolen; if detected on Amazon, report the violation.

Pillar, who had been listening, broke into a cold sweat, and Yue Nan'nan shivered with fear. Master Wang opened his mouth twice but couldn't speak. Xiao Jie exchanged a look with Professor Wang, who then asked, "Is this alien race close to Earth? Why have they chosen our planet?"

Fuer Li explained, "They're not close to Earth. My analysis suggests they initially had no interest in Earth because Earth's life force is too weak for their parasitic needs. Additionally, they don't exist in the same dimensional world as us; they live in another dimensional world with the power of fifth-dimensional beings in a three-dimensional space. Their motives for this cross-dimensional invasion are unclear to me." Each word from Fuer Li sent tremors through the fragile hearts of everyone in the room.

Tang Xiao Jie asked, "How many are there? The demon king you mentioned, is he their leader? How powerful is he?"

Fuer Li responded, "There aren't many of them. Their planet is only a third the size of the moon, with a total population of just over fifty thousand. Including those parasitizing other planets, their numbers don’t exceed four hundred thousand. The third demon king is indeed their leader, a mysterious figure whose capabilities match those of Lucifer and Chiyou."

The room was filled with gasps. Another monster like Chiyou, whom even the highest-level magic couldn’t easily defeat, was terrifying. Fuer Li continued, "Besides informing you of these matters, I have another purpose for my visit."

As soon as she said this, Yue Nan'nan cast a wary look at her, like a jealous woman eyeing a rival. Fuer Li glanced at Yue Nan'nan without reacting and said, "Chiyou and Lucifer are obviously allies, but the Morgada aliens shouldn’t have any inherent connection with them. We can disrupt their plans first, then focus on the other two demon kings."

Yue Nan'nan quickly asked, "How does this relate to your purpose? It seems this catastrophe also affects your fifth dimension, doesn’t it? Otherwise, why would you be so concerned?"

The other fifth-dimensional being beside Fuer Li interjected, "You're right, beautiful young lady. Xuanyuan (the Yellow Emperor) successfully evolved into a fifth-dimensional being and became our great elder. Out of gratitude, he decided to help you."

With this explanation, everyone understood. The battle from 4600 years ago was continuing today, a cyclical relationship indeed. However, Yue Nan'nan had a different perspective. "You wouldn't help us if it weren’t necessary, right? Because Chiyou would inevitably find his way to the fifth dimension, correct?"

The interjecting fifth-dimensional being blushed and fell silent. Fuer Li, unconcerned, said, "You have a point. This time, I am here on behalf of my father to invite Tang Xiao Jie, Miss Yue Nan'nan, Dong Yuan Zhu, and Master Wang Yong to visit the fifth dimension. My father, along with the ten greatest sages of our world, will bestow new wisdom and abilities upon you. We hope you understand our intentions."

Hearing this, Yue Nan'nan finally relaxed and stopped worrying about whether the girl opposite her was a romantic rival. Fuer Li continued, "Xiao Jie, bring your Extreme Heaven Blade. My father said this artifact could become even more powerful."

Xiao Jie, pleased, replied, "Don’t worry. This divine artifact goes wherever I go. You can’t see it, but when I need it, I can summon it with my mind."

This time, it was Fuer Li’s turn to be surprised. She murmured, "No wonder my father said you are the true master of this artifact."

Professor Wang interjected, "Alright then. We’ll split up. I’ll take the samples collected from Dawei and go with the security bureau to Beijing for analysis. You will go with Fuer Li to the fifth dimension. When you return, come directly to Beijing to find me. I’ll send someone here in the meantime."

Everyone agreed with this plan, smiling at each other. Master Wang was the most excited. Since meeting Xiao Jie, his reputation as a sword immortal had faded. If he could upgrade, maybe even his elder brother wouldn’t look down on him anymore. Tang Xiao Jie felt increasingly that life was unpredictable. The Yellow Emperor had become a fifth-dimensional being and a leader at that. Truly, destiny had its way of asserting itself. As for himself, he didn't want to be a king or a hero. One day, having a farmhouse like the contact point and living there with his beloved would be enough. Ideally, living there with Yue Nan'nan would be perfect. But now, as a mission bearer, he had to fulfill his duty. He had to strive forward.
