Yu Zichong was very confident in his words, believing no one could resist the allure of attaining immortality and becoming a celestial immortal. Back then, Doctor Mo had once hated him deeply, yet under the same persuasion, he had eventually cooperated willingly. With just a little sweetener offered, Yu Zichong was certain that the man would surely comply. Yet, Yu Zichong was disappointed. After hearing the enticing proposal, Han Li showed no sign of excitement, his expression calm and composed—as if the words had stirred no ripple in his heart at all. "Regarding cooperation, I will consider it later. But I have one question right now—I hope you can answer it." Han Li gazed steadily into the glowing orb, speaking gently. "Once you answer my question, will you then agree to cooperate?" "It depends on whether your answer satisfies me." "Very well, then—go ahead and ask." Yu Zichong readily agreed, clearly deeply understanding the saying, "When one is under someone's roof, one must bow." Han Li did not immediately speak, but instead raised his head and gazed thoughtfully at the ceiling for a while, as if pondering how to express himself most appropriately. Yu Zichong was startled by Han Li's serious demeanor and kept murmuring to himself, wondering what difficult question Han Li might now raise. "I'd like to know," Han Li finally voiced the concern he had been harboring since waking up, "what adverse effects I might experience after reversing the absorption of Mo Doctor's and your portions of my spirit? Why do I feel a sense of pressure and fullness in my mind, as though there's an abundance of new elements, yet unable to access or examine them? Is there anything wrong with this?" Upon hearing that Han Li's concern was precisely this subtle issue, Yu Zichong immediately felt reassured, his tone now light and cheerful. "Ah! So it's this matter. Brother, you've been overthinking—there's absolutely no need to worry at all." To be clear, the things absorbed into your mind will gradually fade away over the course of one or two years—no effort on your part is needed. "So then, I'm essentially wasting my efforts in consuming these elements? I'm not even able to retain any of them? I don't believe that." Han Li glanced at the other with a skeptical expression, subtly conveying his lack of trust. "It's not entirely true that nothing will remain. However, what does remain is indeed quite limited." Yu Zichong quickly stepped in to clarify, eager to prevent any misunderstanding. "Memories, experiences, and emotions—these are absolutely irreplaceable. If you absorb them, the consequences could range from becoming a complete fool or suffering from personality fragmentation, to experiencing a mental surge so intense that your mind bursts. After all, the spirit is the most delicate of all. It cannot simply blend with other elements. While it's acceptable to temporarily house someone else's spirit within your mind, transforming it into your own is nothing short of a fantasy. Otherwise, merely by seizing someone's spirit, one could gain their experience, memories, cultivation techniques—how could the world not fall into chaos? Who would still diligently practice cultivation, seek enlightenment, or understand the subtle methods of inner cultivation, if all they had to do was simply seize a spirit and be done with it? After explaining the last sentence, Yu Zichong saw Han Li nodding, clearly believing what he had said. He felt a surge of joy and, in his inner light sphere, the glow seemed to brighten slightly. With eager anticipation, he asked, "Han Li, since you're satisfied with my explanation, shall we now discuss the details of our collaboration?" "Of course! To collaborate with a cultivator is the very thing I've longed for!" Han Li suddenly smiled warmly, his white teeth gleaming brightly, conveying sincere enthusiasm. "Really?" Yu Zichong became excited, not expecting that Han Li would already agree without any further persuasion. He quickly opened his mouth to confirm. "Certainly," Han Li replied promptly and clearly. Then, with a warm smile, he withdrew something from his sleeve and said to Yu Zichong in a friendly tone, "Now that we are officially partners, would you mind accompanying me through a small experiment before we proceed to detailed discussions?" "An experiment?" "Yu Zichong was taken aback. He stared at the cylindrical object in the other man's hands, feeling a strange familiarity—as if he had seen it before—his mind already tinged with an uneasy foreboding. "Yes, a poison test," said Han Li, and as soon as he finished speaking, his thumb on the cylinder moved slightly. Immediately, a thick, black liquid gushed out, carrying a foul, putrid odor, and surged straight toward the target across the room. "Ah!" Yu Zichong cried out in pain, his spirit drenched by the black liquid. The green glow surrounding him dimmed suddenly, indicating that he had sustained significant injuries. "You—you have poisoned me! You've attacked me secretly!" Yu Zichong screamed, his voice strained, still struggling to accept what had just happened. Han Li paid no attention to the other's fury. He reached out and grasped the belt buckle at the upper part of his waist. With a swift motion, he drew a gleaming sword from the inner layer of the belt. This sword is as wide as a finger, about one and a half feet long, uniformly flexible throughout—rarely seen, a true "jade-belt short sword." It was the final short sword crafted by the blacksmith, commissioned at great expense, and the most costly of all. However, since the blacksmith was not particularly skilled in such weapons, it had remained unused until now. Unexpectedly, it was finally put to use. Holding this sword, which he had carried with him for a long time yet had scarcely had a chance to deploy, Han Li's expression darkened profoundly; the earlier smile had nearly vanished. With a look of contempt, he fixed his gaze upon the still-trembling spiritual essence, then without a word, took a single step forward and launched a powerful strike directly at the glowing orb, treating the delicate sword as though it were a chopping tool.
