Chapter 751: Chapter 344: Secretly Altering the Array, Elder’s Changing Face Up until now, Zheng Fa could finally say that the “First 50-Year Plan” had a success rate of ninety-nine percent! He watched as Zhang occasionally tapped on the water screen, and a stream of light flew out towards the outside of University Island. Some flew towards the Medicine Garden, some towards the workshops, and others towards Gongkai Island. Zheng Fa knew that this meant Zhang had calculated the results and was issuing orders to various departments within the Jiushan Sect. With the Nine Chapters of Mathematical Array, the entire economic system of the Jiushan Sect was like having a brain. After just a brief period, Zhang set down the pen and looked at Zheng Fa with bright eyes, smiling: “Usually, this kind of thing would take me half a month to calculate.” Zheng Fa grinned; if someone as exceptional as Zhang could take half a month, the time others would take might be no less than half a year. After planning the Jiushan Sect’s resource allocation for this period, Zhang appeared not to have had enough fun, her pen tip once again tapping the water screen, which changed to show a dense array of runes. Zheng Fa naturally recognized that these were the runes of the Heaven and Earth Divine Evil Formation. He couldn’t help but focus his attention. The Heaven and Earth Divine Evil Formation was crucial to his life, so he naturally paid attention. Moreover, if he could add a backdoor to the great array, his room for maneuver would increase significantly, and he might even find a way to obtain the True Inheritance Technique of Haori Mountain. “The backdoor of the Heaven and Earth Divine Evil Formation… the design is excellent, but the only problem is how to inscribe it in the Spirit Stone without being detected.” Zheng Fa watched as Zhang frowned and calculated, shaking his head as well. Shi Nandang wasn’t a fool; at least for now, he didn’t fully trust Zheng Fa or even the three Nascent Souls of the Chongxuan Sect. He would inspect every Spirit Stone they imprinted. If the spells in the Spirit Stones differed, he would naturally notice. Zhang nodded slightly, the Fei Xian Pen tapping continuously on the water screen, her frown growing deeper. After a while, her eyes suddenly brightened as if she had thought of something, tapping the water screen, “Junior Brother, take a look at this!” Zheng Fa looked at the water screen. He saw that the screen now displayed a complex yet familiar talismanic diagram structure. He looked for a while and suddenly laughed, “Senior Sister, you’re really… bullying people!” The talismanic diagram structure on the screen was ninety-nine point nine percent similar to the one Zheng Fa originally intended to inscribe in the Spirit Stone. But upon closer inspection, it contained many additional structures compared to the original talismanic diagram— But Shi Nandang probably wouldn’t notice: Originally, Zheng Fa and others used topology to simplify various talismanic diagrams, pursuing minimal Spiritual Power consumption. But Zhang went against this, using topological transformations to twist and distort some diagrams, complicating them while making them appear almost identical to the original, yet their topological nature was drastically different. Students good at topology in the Jiushan Sect might notice it. But Shi Nandang hadn’t studied this at all! It’s about taking advantage of Shi Nandang’s lack of knowledge! “Senior Sister, I think other talismanic diagrams can also try this…” Zheng Fa surprisingly began to push his luck; he originally just wanted to quietly leave a backdoor to ensure his safety. Now he was considering whether to tear down the entire backyard. Chongxuan Sect, Divine Fire Mountain. “Come to my cave residence.” A transmission sounded from the mountainside, and Zheng Fa, without hesitation, flew toward the cave residence of his affordable master, the Ninth Elder. Official source ıs 𝙣𝙤𝙫𝙚𝙡•𝙛𝙞𝙧𝙚•𝙣𝙚𝙩 Inside the cave, only the Ninth Elder was present. She sat on the Cold Jade Bed, with a storage bag placed by her knee, seemingly examining it. Zheng Fa’s gaze also fell on the storage bag, his mind stirring as he partially understood the reason she summoned him. “These are supplies sent by my people…” As expected, the Ninth Elder’s words confirmed his guess. This storage bag contained the goods from the trade between the Supreme Dao and the Jiushan Sect. Currently, the transaction between the two sects was actually conducted through the Ninth Elder’s channel, with Zheng Fa handing over the goods to her, and she transporting them to the border of the Supreme Dao and then bringing back their goods. As for which items were exchanged and at what prices, these were naturally negotiated by Zheng Fa with the Tongming Master using a Communication Talisman. Actually, the volume of traded goods wasn’t large. Yes, to be factual, it couldn’t even compare to the economic contribution of Haori Mountain to the Jiushan Sect. After all, the Ninth Elder didn’t dare to be too blatant, as it was essentially smuggling. But the trade was nonetheless crucial to the Jiushan Sect: Because in the East Continent, the lands occupied by the Supreme Dao were the largest and its resources the most abundant, possessing many spiritual materials unavailable to the Hundred Immortals Alliance. Some spiritual materials required conversion to obtain, at costs far exceeding those of trading with the Supreme Dao, making it practically uneconomical. Hence, the Ninth Elder could be considered to have significantly aided the Hundred Immortals Alliance. Zheng Fa also took out a storage bag, handing it over to the Ninth Elder. “This is the reward for the Elder.” Zheng Fa always respected working people, and it was the same for the Ninth Elder as a courier, which was what they had agreed upon— The Ninth Elder helped him deliver goods, and Zheng Fa compensated with Spirit Stones and resources. Unexpectedly, the Ninth Elder shook her head, seemingly intending to refuse. “…The one trading with your sect from the Supreme Dao is a person of considerable status, isn’t it?” The Ninth Elder was able to guess this, and Zheng Fa wasn’t surprised. He had previously told her to pick up goods at the Supreme Dao’s border. But the spiritual materials in this storage bag were rich and valuable. Many were exclusively owned by the Supreme Dao. Without a certain status within the Supreme Dao, it would be impossible to obtain so much. Behind the Tongming Master was the Xuande Chief, a person seemingly at the Corpse Dissolving Cultivation level, only a step away from the Dao Fruit within the Supreme Dao system.
