As the voice faded, a golden magical sword appeared in Lu Qingshan's hand. With the magical sword in hand, his entire demeanor instantly became more formidable. The already vigorous and sharp character of his spirit immediately turned fierce and compelling, as if he were about to tear the sky asunder and rearrange the sun and the moon. This caused both Lu Quanzhen and Lu Wangshu standing nearby to be exceedingly astonished. They had not expected that this brother, who had returned after many years away, would be so astonishingly formidable. Especially Lu Wangshu. Confronted with Lu Qingshan's sharp and powerful momentum, he even felt his heart palpitate. Seeing this, Lu Changsheng also inwardly praised him. As expected of a Fourth Rank Seed of Law! Not to mention anything else, just this aura alone would cause an ordinary Energy Refining Cultivator to weaken significantly upon encountering it. "Dad, be careful," Lu Qingshan said, his magical sword trembled lightly, giving his father a heads-up. Facing his mentor, Tianyuan True Immortal, he would draw his sword without any reservations. But his father was, after all, a Foundation Establishment Cultivator. Moreover, listening to his grandfather's words, his father's prowess lay in Talismans. Thus, he was worried about inadvertently injuring his own father, which would be unfilial. "Just strike without worry," Lu Changsheng said, his tall and straight figure standing with one hand resting behind his back, like an ancient pine or cypress, as elegant as a handsome tree facing the wind. "First Yang!" The magical sword in Lu Qingshan's hand thrust straight out, and in an instant a white-gold Sword Qi burst forth. "Whoosh!" Lu Changsheng lightly raised his right hand, his two fingers came together, and a burst of Sword Qi shot out, erasing his son's Sword Qi. "Continue, there's no need to hold back," Lu Changsheng said calmly and indifferently. "Understood!" Lu Qingshan, realizing he couldn't possibly harm his father, immediately went all out. "True Yang Twelve Swords! Whoosh whoosh whoosh!!!" A fierce and brilliant golden brilliance burst forth from Lu Qingshan's magical sword, making it seem as if a round of golden sun were emerging behind him, shining with dazzling light. These sword lights all surged toward Lu Changsheng. "Such power, is this the strength of an Immortal Sect disciple!?" Lu Quanzhen, looking on from the side, felt as if waves of awe and shock surged in his heart. He had been away for many years and was aware of the strength of Loose Cultivators and Family disciples. Even though he had never crossed swords with an Immortal Sect disciple. Yet because of the Cultivation Technique taught by his uncle, which laid a robust foundation, he did not believe an Immortal Sect disciple would be stronger than himself. But now, seeing Lu Qingshan's prowess, he realized he had been somewhat arrogant before. "Hum hum hum!!!" An energy shield formed around Lu Changsheng, who stood quietly amidst the sword light, allowing the Sword Qi to attack. A moment later, all the Sword Qi dissipated, and Lu Changsheng still looked as graceful and dignified as before. "Not bad," Lu Changsheng said, looking at his son and giving his comment. His words were genuinely heartfelt. Even though he was at the Ninth Level Energy Refinement and possessed the Profound Origin Bead, he wouldn't dare say for sure he could beat his son Lu Qingshan without using Talismans or Puppets. At this moment, seeing Lu Qingshan's strength, he felt much more at ease about the upcoming journey to the Purple Shadow Secret Realm. It seemed that it was precisely because of Lu Qingshan's abilities that his mentor, Tianyuan True Immortal, felt confident to send him to the Purple Shadow Secret Realm. Considering such a perilous Secret Realm as a trial to temper himself. "Did you integrate the Seven Luminaries Great Freedom Sword Scripture with your Great Gengjin Sword Art in this sword technique?" Lu Changsheng asked Lu Qingshan. He detected a trace of the Seven Luminaries Sword Scripture in that strike. "You can tell with just one look, Dad. You're amazing," Lu Qingshan said with a grin, buttering up his father. This demeanor was in stark contrast to the earlier sharpness and unrivaled spirit, creating a strong contrast. This left Lu Quanzhen truly unable to understand his brother. Aren't Sword Cultivators supposed to be uncompromising and full of pride? His brother did seem to fit the description of the Sword Cultivators as mentioned in the books, but now... Lu Wangshu, seeing Lu Qingshan act this way, curved her beautiful eyes into a smile, revealing an amused and somewhat empathetic expression. After asking briefly about his son's Sword technique, Lu Changsheng made a few comments and then stopped there. Given Lu Qingshan's condition, his natural talent in the Sword Dao meant he could carve his own path and didn't need too much guidance from him. Saying too much might actually affect Lu Qingshan. "Quanzhen, what do you think of Qingshan's strength?" Lu Changsheng asked his other son, Lu Quanzhen. "Qingshan's strength is greater than mine," Lu Quanzhen shook his head in reply. He felt within his current abilities, it would be difficult to block that sword from before. "Qingshan will also go to the Purple Shadow Secret Realm this time," Lu Changsheng continued. "Qingshan is going to the Purple Shadow Secret Realm?" Lu Quanzhen was surprised. "Yes, Brother Quanzhen, are you also going to the Purple Shadow Secret Realm?" Lu Qingshan asked, raising his eyebrows. He had some impression of Lu Quanzhen. He was very smart in school earlier on, but his talent for cultivation seemed to be only average. However, looking at Lu Quanzhen, he discovered the latter's Cultivation Level had been concealed, preventing him from seeing through it. "Yes, Quanzhen will also go to the Purple Shadow Secret Realm, and when the time comes, you can look after each other," Lu Changsheng said. "The Purple Shadow Secret Realm? Daddy, is that the Purple Shadow Secret Realm that opens every thirty years? I want to go too!" Lu Wangshu's interest was piqued upon hearing this. "Do you think the Purple Shadow Secret Realm is child's play?" Lu Changsheng immediately retorted, tapping on his daughter's forehead. "I was just saying, Dad. If you keep tapping like this, you'll make your smart and cute daughter stupid," Lu Wangshu pouted, playing the innocent. "Dad, don't worry," Lu Qingshan nodded in response. "Father, I'd like to spar with Qingshan, to see the gap between us," Lu Quanzhen said at this moment, looking at Lu Changsheng. Although he felt his combat prowess was not as good as Lu Qingshan's, he wanted to see the specific gap.
