Boss Jiang spoke with utmost respect and even some fear in his words. "Those associated with Boss Jiang are likely not good people..." "Calling him ’Gentleman’ would mean he’s not a brute, not a Body Cultivator, not a hands-on executioner..." "He’s either a Calculation master or a Formation Master, or possibly both?" "Could this Four Symbols Formation be the creation of ’Mr. Tu’?" ... Mo Hua nodded slightly, a clear goal gradually forming in his mind: To capture this mysterious "Mr. Tu." He was sure to possess the inheritance of the Four Symbols Formation, and it certainly wasn’t just any ordinary inheritance. This "locking class" Formation Pattern made Mo Hua feel it was incredibly profound, close to the deepest mysteries of the Four Symbols Formation, and it even had a hint of the ’Five Elements Source Pattern’... Mo Hua couldn’t help but lick his lips. This Mr. Tu... was like a fat sheep! If he could really capture him, not only could he shear this sheep, but he could even eat the meat, roast the ribs, and use the bones for soup! Then there was Yu Er... Their intentions towards Yu Er were definitely not benign. He couldn’t let them off. However, this "Mr. Tu" likely had high Cultivation and substantial Array Formation Skill. Even his Calculation skills were probably sharp... And he was hidden in the shadows, which meant he wouldn’t be easy to expose... "We need to find some clues, and plan this carefully..." "If all else fails, report to the Taoist Court, and involve Taixu Gate, the Shangguan Family, and the Wenren Family, with Uncle Shangguan and Aunt Wan..." Mo Hua counted on his fingers, realizing that he actually didn’t need to act personally; there were plenty of "hired thugs." He just needed to play smart and "pick up the pieces." Mo Hua nodded, feeling this approach was safer. "But how can I find this ’Mr. Tu’?" Mo Hua went through everything that had happened after entering Qian State in his mind, realizing that clues about Mr. Tu were dismayingly scarce. The most obvious was the "human trafficker." Mo Hua silently thought, "It looks like my future Sect missions should specifically target these traffickers’ bounties..." "And there’s also Boss Jiang, and Bald Eagle..." "Though they are dead, their social connections are still there, and birds of a feather flock together; they’re likely all Sin Cultivators wanted by the Taoist Court." "Find these people, subject them to harsh interrogation... no, ’reform’ them with Fireball Technique; once their conscience is awakened, they should tell me some truths..." "And then there’s..." Mo Hua took out a jade token from his Storage Bag. It was the Letter Token that had been in Bald Eagle’s possession. He had checked it, and it was clean, blank inside. But being a Formation Master, he knew the principle of "from nothing comes something." "Existence" can become "non-existence," and "non-existence" can also transform into "existence." Furthermore, Uncle Zhang Lan had also warned him, "Rain leaves traces, geese leave sound, and a Cultivator, in anything they do, always leaves a mark..." Invisibility doesn’t mean non-existence. Mo Hua planned to study and see if he could find any clues about Bald Eagle’s connections from the Letter Token. To see whom he had communicated with, what words he had conveyed. ... For the next two days, Mo Hua spent his time studying the Letter Token, yet he made little progress. He still knew nothing about the secrets within the Letter Token. Mo Hua sighed. Indeed, developing theories in isolation wasn’t working... His skills and experience in Array Formation weren’t sufficient to quickly unravel the mysteries of an unfamiliar formation, even though he was skilled in both Tricky Calculation and Heavenly Secret Calculation. However, he was now a Sect disciple at Taixu Gate, and it was time to learn and ask... Mo Hua went to ask Elder Master Xun. There were some questions that couldn’t be asked. Such as the Taixu Mind Transforming Sword True Art, or things related to Heavenly secret Tricky Calculation and Heavenly secret Calculation. But asking about the "Letter Token," which didn’t have significant Karma, should be fine. Elder Master Xun was somewhat surprised and asked, "Why are you suddenly asking about the ’Letter Token’?" Mo Hua shyly replied, "I came from Little Immortal City in Li State and had never seen a Letter Token before, so I got curious..." "I think the Letter Token must involve some basic Array Formation principles, but I’ve been pondering it for a few days without a clue, so I came to ask you, Elder..." Elder Master Xun nodded slightly. To be inquisitive and to seek knowledge. To be curious about things, to reflect on one’s thoughts. To be able to ask humbly when in doubt. Good... Elder Master Xun was pleased. As for the matter of the "Letter Token," although it was a bit early to teach him, giving him a few pointers in advance would help him be prepared, doubling the efficiency when he actually learned it... Elder Master Xun thought to himself, then said, "This kind of formation is complex, not suitable for your current learning, but since you’re curious, I’ll tell you some basic principles of Array Formation, just so you know..." "But don’t reach too high and waste too much effort, stick to learning the regular formations solidly step by step..." "Right!" Mo Hua nodded repeatedly. Elder Master Xun then said, "The Letter Token is used for communication; the Array Formation involved is of the Eight Trigrams type, specifically the ’Zhen’ series, also commonly known as the ’Thunder Pattern’ formation..." That was within Mo Hua’s expectations. Mo Hua thought for a moment, then asked, "Elder, is the Thunder Pattern related to ’Original Magnet’?"
