Gu Changhuai: "…" He felt that the issue probably wasn't with the Formation Master, but with Mo Hua instead. However, Mo Hua had stopped paying attention to him and took the lead, walking along the path toward the convergence of the Yuan Magnetic Formation. Gu Changhuai's gaze sharpened, he sighed, and could only silently follow. At the end of the little path, there was a wall. It was built of sturdy stone, carved with strange patterns and reinforced with Formations, but it looked no different from other walls in the area. The place was secluded with no one else around. Mo Hua felt and knocked on the entire wall, inch by inch, checking everything. He then stopped in front of a wall brick that bore the carving of an eye and pondered. There was something off about this brick... After locking eyes with the "eye" on the brick a moment later, Mo Hua took out his brush and ink, drew Formation Patterns around it, and broke the Earth Stone Formation reinforcing it. Cracks began to appear all around that very brick. Gu Quan stepped forward, removed the brick, and revealed a dark passage behind it. The passage was narrow, barely tall enough for half a person, and inside there was thick, crude Blood Ink. This ink was a trace of the Formation Pivot. Mo Hua's eyes gleamed faintly. He had guessed correctly. Just like when he constructed the Five Elements Slaughter Demon Great Formation, since it was necessary to use the Formation Pivot to control all the Single Formations, the ink "body" of the Formation Pivot had to connect the inner and exterior halls. At the same time, these Formation Pivots had to be concealed within the structure, unexposed. To prevent someone like himself who had intentions from targeting them. But no matter how well they hid, they still couldn't escape his clever detection... Mo Hua nodded in self-satisfaction. Next, he just needed to follow the trail, find the central control of the Compound Formation through this "vine" of Formation Pivots... The problem was... Mo Hua glanced at the entrance and then turned back to say to Gu Changhuai and the other two, "You guys are too tall, seems you won't fit in there..." Gu Changhuai and the others had complex expressions. They couldn't possibly shrink themselves on purpose just to squeeze through this hole... Mo Hua sighed, "No choice then, I'll go take a look..." Gu Changhuai frowned, "You're going alone?" "It's okay," Mo Hua said, "this is where the Formation Pivots are hidden. I'm very familiar with it, there won't be any danger..." Formation Pivots were supposed to be kept secret. Not only must they remain unknown to outsiders, but even insiders were forbidden to approach. The buildings near the Formation Pivots would only have some Early Warning defensive measures when building the Formation. But to Mo Hua, who had constructed the Large Formation himself, these measures weren't even worth mentioning. Gu Changhuai pondered, "You could take a Shrink Bone Pill, to temporarily reduce your size..." "Shrink Bone Pill?" Mo Hua was surprised. There was such a thing? The Tao Cultivation World truly had all sorts of oddities. Mo Hua thought for a bit but then shook his head, saying: "Shrink Bone Pill won't work, the flow of Spiritual Power is chaotic inside the Formation Pivot, which could easily affect the Formations on the Spiritual Artifacts, causing them to malfunction..." Mo Hua pointed at the Jade Pendant on Gu Changhuai's body, "Your Water Concealing Jade might be affected and fail to conceal you..." Gu Changhuai's gaze darkened. He hadn't considered this... After all, he wasn't a Formation Master and had only a shallow understanding of the subtle formation principles. "No, wait..." Gu Changhuai suddenly realized, "If our Water Concealing Jades become ineffective, doesn't yours become useless as well?" "I'm different," Mo Hua said. "I know Concealment Techniques." Gu Changhuai opened his mouth, at a loss for words: "When did you learn Concealment Techniques?" Mo Hua looked innocent, "I've always known how to do it..." Always known... Gu Changhuai wore a look of feeling deceived and couldn't find words to reply. "You never asked me..." Mo Hua muttered. If Uncle Gu didn't ask about the Concealment Technique, surely he had no reason to mention it... Gu Changhuai took a deep breath, glanced at Mo Hua, "Then why did you just accept the Water Concealing Jade I gave you?" "That's quite complicated..." Mo Hua spoke with conviction, "According to my research, combining Concealment Spiritual Tools with Concealment Spells can produce a dual hiding effect, providing even better concealment..." "The Demon's Cave is so dangerous, for a small Foundation Establishment Cultivator like me it's like walking on thin ice. The more thorough my survival methods, the better..." Gu Changhuai suddenly felt that Mo Hua made a lot of sense... Except throughout this journey, Mo Hua had been moving with such light steps, he didn't seem to be "walking on thin ice" at all... Gu Changhuai sighed. The surrounding air was eerily filled with Yin Qi, and a ghastly green glow was everywhere. Beneath the stone corridor, thick and foul-smelling rotting water flowed... Being in the middle of the Demon Palace wasn't the time to dwell on these issues. Moreover, a Concealment Spiritual Tool, no matter how precious, truly could not compare to Mo Hua's safety. Gu Changhuai sighed, "Alright then, be careful..." He thought for a moment, then added: "If you encounter any danger after entering, just call for help loudly, and I'll find a way to rescue you..." Mo Hua was somewhat surprised, nodding, he said: "Don't worry, Uncle Gu." Having discovered the Formation Pivot, the dangers of the Demon's Cave seemed diminished. Then, Mo Hua alone and crouching, entered the passage behind the wall at the Formation Pivot, using his hands and feet to move along slowly, following the pathway of the Formation Pivot, inching his way toward the core of the Yuan Magnetic Formation. The stone path was cramped, occasionally flattening out, sometimes vertical and steep. Above, there were Yuan Magnetic Formation Pivots as well as some Early Warning Formations. Mo Hua avoided these Formations and simultaneously used the Water Passing Step, applying Spiritual Power to his hands and feet, using Divine Sense to guide him, clinging to the walls, and carefully advancing in the Formation Pivot passage like a "little gecko." The magnetic current he had sensed before was only a weak flow of water.
