"Ah, Brother Han, you're referring to the 'Concentration and Unity Technique,' aren't you? Indeed, this technique is remarkably extraordinary. However, it's quite demanding—first, the practitioners must be full-blooded siblings from the same lineage, and second, their cultivation methods and attainments must be quite similar in order to perform the technique. The Qing clan differs from other clans in that most of their offspring are born as twin or multiple siblings, with six or seven siblings in a single birth being quite common. Yet, after growing older, they can eventually separate on their own. At the four city gates of Yun City, there are Qing clan members stationed specifically to detect those entering the city. Once the technique is activated, the consciousness of several individuals merges into one—no matter how much higher their cultivation level, even three or four tiers above, they cannot escape detection." Tianmu smiled and added a few remarks. "Now I understand! Brother Han, I truly lacked knowledge in this matter. Nevertheless, I am quite interested in this technique. Would you kindly share with me the method of practicing it?" After listening carefully, Han Li felt initially a bit disappointed, but upon reflection, he found the technique truly marvelous and began to take interest in adapting and refining it. He thus asked, "The Concentration Technique is not particularly emphasized by the Qing clan. Although it circulates less outside the clan, I am still able to locate a copy. If my friend truly wishes to have it, I will arrange to reproduce one for you." Jia Tianmu spoke with exceptional generosity. "Thank you very much," Han Li replied, smiling and bowing in gratitude. "That's nothing at all. Master Han has saved my life on more than one occasion—what could this possibly be? By the way, I need to pay a visit to several elders within the clan first. I may not be able to accompany you further. This is my dwelling in Yun City. You may visit any time within a few days to collect the spirit-controlled automaton I previously promised. I must confess, I have several such automata in my residence, but when I wish to gift one to a foreign clan, I still need the approval of the elders. However, please rest assured." "I still hold a certain status within the clan, so there's no question about this matter." Tianmu smiled, lifted a stone slab and handed it to Han Li, then spoke his parting words. By this time, the two had already stepped out of the city gates, and before them lay a broad avenue lined with shops of varying heights. While not bustling, it was far from deserted. "That's fine. I have my own matters to attend to, so I'll bid you farewell here." After receiving the stone slab, Han Li used his divine awareness to briefly scan it, then smiled and replied. "In Yun City, the Tianyun clans live together, and there are many outsiders as well. Some residents stay for several hundred, even thousands of years. Besides temporary accommodations, there are also dedicated rental cave-fortresses. However, the cost is quite substantial. Yet if Brother Han intends to remain in the city for an extended period, I believe this expense will surely be manageable." Moreover, Master, there's one thing you must remember—within the city, avoid any disputes with others or unnecessary use of your spiritual energy. Otherwise, should the seal detect your actions, you may be expelled from Yuncheng, or even have your spiritual abilities and cultivation permanently compromised. This principle is one that even our thirteen clan elders would never easily break. With that, I shall now step down. Jia Tian Mu specifically shared many more details, and then truly turned into a mortal, departing without further hesitation. Han Li did not attempt to detain him, merely watching from afar as Jia Tian Mu boarded a spiritual carriage drawn by two deer-like spiritual beasts, and then swiftly vanished toward the far end of the street. Only then did Han Li turn his gaze back and carefully examine the buildings lining the streets. Indeed, this city is no ordinary one—home to the thirteen great clans—the buildings are not only densely packed but also vary greatly in style, so that upon first glance, no two shops appear to be alike. These buildings ranged from over a hundred zhang in height, towering like small mountains, to those only a few zhang high yet exquisitely refined and graceful; some were square and resembled human-style pavilions, while others bore the form of a colossal tree, their entire bodies shimmering with lush, emerald green hues. Han Li only took a moment to observe them, and by then, he was completely captivated by the city. In reality, the war between the Jiaochi clan and Tianyun has erupted almost periodically. Either the Jiaochi clan has invaded and seized certain territories of Tianyun, or the thirteen Tianyun clans have united to reclaim their lost lands. Of course, in most cases, the more powerful Jiaochi clan has held the upper hand. Yet, through mutual support and complementarity among the Tianyun clans, they have not suffered significant setbacks. Thus, when the Jiaochi clan launched its sudden offensive this time, the upper echelons of the Tianyun clans were not surprised and swiftly responded, mobilizing their forces to prepare for a strong counteroffensive. These details were casually revealed by Han Li during his journey alongside Jia Tianmu. According to Jia Tianmu, while Tianyun indeed spans an exceptionally vast area, it is not the only neighboring powerful clan—the Night Clan, whose strength rivals that of Tianyun, and the Bo Ming Clan, slightly weaker than Tianyun, also exist in the region. Additionally, there are numerous smaller clans located nearby. Yet, generally, these smaller clans could only secure a foothold in the region by attaching themselves to or joining the larger clans. Otherwise, they would either be erased or driven far away, seeking new homes. This gave Han Li a general understanding of the conditions of the various clans in the region. Now, as he glanced at the streets on either side and walked steadily, he swiftly pondered his next course of action. Undoubtedly, his primary objective remained finding a super teleportation array capable of directly transporting him back to the Tianyuan Continent. However, such high-tier teleportation arrays could not be held by individuals—they were certainly in the hands of certain major powers. To utilize them, he would likely have to engage with the upper echelons of these powerful clans. This was also the reason he had not outright declined Jia Tianmu's invitation initially. Whether or not he would ultimately need to meet with the upper leadership of the Tianyun Clan would still depend on the information he gathered. What he now urgently needed to do was first find a place to settle in Yuncheng, and then gradually piece together the clues step by step. Once his plan was settled, Han Li no longer hesitated. He swept his gaze over the shops around him and casually chose a building resembling a human-style pavilion, walking toward it. The shop was not large, only two stories high. Inside, the displays on the shelves were varied and diverse, suggesting it was a typical general merchandise store. The store owner was a green-skinned member of the Moku Green race, originally seated behind the counter in a chair. Upon seeing Han Li approach, he immediately rose with a warm smile and greeted him warmly: "Senior, what would you like to purchase? Our store specializes in several specialty items from Yun City—maps, and some others…" Though this mid-40s outsider had only a Foundation Stage cultivation level, he showed no hesitation in front of Han Li, bowing first and then delivering a smooth, fluent series of introductions. It's no wonder, given the relatively low level of the other party—likely even the Yuan Ying and Lian Xu stages wouldn't be able to distinguish Chu. In Yun City, however, many individuals possess profound修为, and having seen so many such cases, they naturally come to adopt this manner of behavior. "Bring me a detailed map of Yun City, the more detailed the better. Also, I'd like to ask you a few more questions," Han Li glanced at the person before him, then suddenly moved his sleeve, sending a mid-tier crystal flying out. As he did so, he spoke softly. "This is our store's finest map! Should the elder have any questions, please don't hesitate—my utmost effort will be made to answer them fully!" Upon receiving the crystal, the shopkeeper immediately beamed and swiftly retrieved a pale red stone plate from the shelves, offering it to Han Li with evident enthusiasm. ...After a cup of tea's worth of time, Han Li stepped out of the shop with a composed expression and casually stopped a carriage on the street. He mentioned a destination to the driver and then settled into meditation within the carriage. The driver immediately set the carriage in motion, driving it swiftly forward. The beast-carriage carried Han Li toward one corner of the nearest cloud city. After crossing countless streets, it finally came to a halt in front of a towering, strangely shaped structure after two hours. Han Li casually set aside a few spiritual stones, then stepped down from the carriage and calmly surveyed the building before him. On either side of the great gate, strange characters are inscribed—so unusual that even with the multitude of foreign scripts that Fan Li has mastered, he cannot identify which ethnic script they belong to. Without hesitation, Fan Li stroked his chin and then stepped forward toward the gate. Upon entering, he found himself in an astonishingly spacious hall! The hall was over two hundred paces wide, with lush emerald jade laid out along the walls and floor. Rows of flowerpots several feet high stood around, each housing vibrant, radiant spiritual flowers and herbs. In the center of the hall, however, stood a solitary, dark, and weathered wooden table, upon which a man with snow-white hair and dressed in gray robes lay motionless—his face obscured. It seemed as though he were asleep. "I'd like a quieter room," Fan Li said softly as he approached the table. "I intend to stay for several days."
