Before formally starting work, the big array needed a site selection. Zhou Zhangsi and Elder Yu specifically sought out Mo Hua to ask for his opinion. The big array was drawn by Mo Hua and also designed and built by him, so the site selection naturally had to be decided by Mo Hua. After careful consideration, Mo Hua finally set the location for the big array at Heishan Zhaibao.

The Wuxing Tudemon Big Array is a trap-kill type of big array, not a defensive protective array for a sect. Therefore, it cannot be placed in Tongxian City and must even be far away from Tongxian City. Otherwise, once the big array is activated, Tongxian City will be affected by the killing spiritual power waves of the big array. The most suitable location is in the deep mountains. The best choice is to directly suppress and kill Feng Xi in the deep mountains, preventing it from entering the city. In the deep mountains, the most suitable place is naturally Heishan Zhaibao. Heishan Zhaibao is situated between two mountains, easy to defend and difficult to attack. In other words, the interior is relatively enclosed, which is also suitable for array trapping and killing. The Qian family’s old ancestor built Heishan Zhaibao here also because the location of Heishan Zhaibao is suitable for constructing arrays. Moreover, although Heishan Zhaibao was destroyed, it still retains some array foundations. Building the big array on this foundation can save a lot of effort. Although Zhou Zhangsi and Elder Yu were somewhat surprised, they both nodded in agreement.

Mo Hua then said to Commander Yang: “Uncle Yang, on Feng Xi’s side, we still need to find a way to contain it a bit and delay for some time.” The big array takes a minimum of two months to build, but if there are accidents and the construction period is delayed, and it hasn’t been built yet, and Feng Xi starts seeking food, that would be a big problem. So, we need to do our best to prevent Feng Xi from refining blood energy and buy more time. Commander Yang nodded: “Rest assured, I have used the Yang family’s connections and already submitted a report to the Daobing Department, requesting the transfer of two branches of dao soldiers. In the coming days, we will try to harass Feng Xi and delay its speed of refining blood energy.”

After that, everyone divided the work clearly. Zhou Zhangsi was responsible for allocating spirit stones and materials, Elder Yu was responsible for dispatching manpower, and Mo Hua was fully responsible for the array formation. The Wuxing Tudemon Big Array then officially began construction.

The overall diagram of the big array was designed by Mo Hua based on the big array’s core, referencing records of other big arrays, and listening to the opinions of master craftsmen. First, they cleared the damaged buildings of Heishan Zhaibao and reconstructed the foundation and framework of the big array. This part was the responsibility of the craftsmen. At the same time, the refining workshop in Nancheng worked day and night, the refining furnaces did not stop day or night, and they began refining the components needed for the big array, such as array disks, array locks, and array doors, as array mediums. The alchemists then refined some pills for dispelling heat, detoxifying, removing miasma, and restoring physical strength and spiritual power, to supply to the craftsmen building the big array. Fushan Lou and the An family’s dining hall in the city provided meals for everyone.

The demon hunters, led by Yu Chengyi, Mo Shan, and others, opened a road in Daheishan starting from Tongxian City, passing through the inner and outer mountains, straight to the deep mountains, leading to the mountain path of the old site of Heishan Zhaibao. The mountain path followed the mountain terrain, winding, wide, and flat, convenient for transporting the many materials needed for the big array. At the same time, the demon hunters were also responsible for driving away the demon beasts on both sides of the mountain path to prevent them from attacking cultivators.

Several days later, some scattered cultivators from Qingxuan City also came to help. Cultivators from some nearby immortal cities heard that Tongxian City wanted to build a big array against a great demon, and they all gathered to contribute their strength. The number of cultivators building the big array also increased, and the entire cultivation project became more and more grand.

Mo Hua stood on a mountaintop at Heishan Zhaibao. Looking down, he could see a continuous mountain road, starting from the foot of Heishan Zhaibao, winding along the terrain of Daheishan, and extending all the way to Tongxian City. The mountain road was crowded with people, densely packed cultivators, orderly transporting cultivation building materials and various materials. The Heishan Zhaibao under his feet had already been dismantled and rebuilt the foundation, and some basic frameworks of array mediums had already been set up. Master Ban led numerous craftsmen busy in it, and the prototype of the big array had initially appeared.

And in the distant Tongxian City, the refining workshop was blazing, the alchemy workshop’s furnace fires were prosperous, and Fushan Lou’s cooking smoke rose. The prepared food boxes, pills, and spirit tools were either delivered to the hands of various cultivators or sent along the winding mountain road into the deep mountains… Tens of thousands, even hundreds of thousands of cultivators, united their efforts to build a large-scale cultivation array – the Wuxing Tudemon Big Array.

This scene made Mo Hua feel an inexplicable shock in his heart. “This is a big array…” If a single array is not strong enough, then gather enough single arrays and form a big array through the core array hub. If a single cultivator is not strong enough, then gather enough cultivators and work together with all their might for a common goal. Human power has limits, but as long as there are enough people, power is endless. In a daze, Mo Hua’s heart was enlightened. He could draw a big array, kill Feng Xi, and save the cultivators of a city. But in reality, it was not him saving others, but all people saving themselves. Without him, no one would draw the big array, but without so many cultivators united as one, it would be fundamentally impossible for him to build the big array. Fate never relies on one person to change, but only when all cultivators unite their efforts can they truly go against heaven and change fate!

In an instant, Mo Hua’s sea of consciousness slightly trembled, his divine sense brightened, and he only felt a sudden thorough understanding of the concept of the big array. The once somewhat awkward array hub patterns seemed to be clearly engraved in his sea of consciousness. A trace of enlightenment was suddenly born, and Mo Hua had a feeling in his heart. He could really build and control the entire Wuxing Tudemon Big Array as if commanding his arm!

Master Luo, who was following behind Mo Hua, was sighing at the complexity of the big array. Suddenly, he looked up and saw that Mo Hua seemed to be enlightened, his whole body emitting a mysterious aura that was difficult to fathom. It was as if he had understood some principle, and his array formation had taken another step forward. He even faintly had a bit of the demeanor of an array formation grandmaster. At that instant, Master Luo still thought his eyes were blurred. He rubbed his eyes, looked again, and found that Mo Hua’s body had no profound aura, he was still that pure little cultivator. Because noon had arrived, someone shouted “meal time”, and Mo Hua used his Passing Water Step, happily running to get a chicken leg… Master Luo stood blankly in place for a long time, then sighed with a complex expression and muttered to himself doubtfully: “Was my eyes not blurred just now…”

Ten days later, the framework of the bottom layer array mediums of the big array was built. Thanks to the united efforts of all cultivators, this speed was much faster than Mo Hua had expected. Next, they just needed to draw the formal array formation. The Wuxing Tudemon Big Array takes the array eye as the source, the array hub as the coordination center, the single arrays as the layout, and the array mediums as the foundation stone. The array eye of the big array is composed of multiple first-grade Spirit Gathering Arrays, used to refine spirit stones, absorb spiritual energy, condense array formation spiritual power, thereby providing the spiritual power source for the operation of the entire big array. The core of the big array is the array hub, which is the central hub for coordinating and controlling the opening and closing, starting and stopping, forward and reverse, strengthening and suppressing of spiritual power. Only after drawing the array hub well can the single arrays extending from the array hub be successively laid out. Similarly, among the entire big array, the array hub is the most difficult to draw, and also the most core and most secret part of the big array, and must be penned by the main array master personally. Or rather, only by being able to draw the array hub can one have the qualification to become the main array master of the big array and lead the construction of the big array.

Mo Hua chose a high peak for the position of the array hub. The terrain here is high, the view is good, and the distance from the central area of the trap-kill is relatively far, which is both suitable for overlooking the overall situation when controlling the big array and not easy to be affected by spiritual power during the trap-kill of Feng Xi. The array medium of the array hub is a very large array disk made of refined iron, which is extremely sturdy and not easily damaged. Before Mo Hua started writing, Master Luo led all the array masters to retreat. The array hub is the core of the big array and also the secret of the array master. Naturally, it must be kept secret when drawing. At the same time, Master Luo also knew that this array hub was not necessarily drawn by Mo Hua personally, it might have been penned by his master, so he led all the array masters out to prevent this matter from being exposed. Master Luo was very “considerate” of Mo Hua. But he did not know that the array hub of this big array was indeed penned by Mo Hua personally.

The array hub was very difficult to draw. Although Mo Hua had already understood it thoroughly enough, drawing this array hub was still very strenuous. Using an array disk cast from refined iron as the array medium, drawing the array formation consumed more divine sense. Mo Hua, due to insufficient divine sense, failed twice, then used Spirit Erasing Liquid to wipe away the array patterns and redraw. Again, because the patterns were too complex, he made mistakes in two places and redrew again. After continuously failing five or six times, Mo Hua was not discouraged. Because he benefited from the earlier enlightenment, the patterns of the array hub were clearly presented in his mind. He knew that he could draw it out, he just needed more familiarity and some trial and error opportunities.

Five days later, after Mo Hua had attempted countless times, the array hub of the Wuxing Tudemon Big Array was finally drawn out by him. Mo Hua penetrated the array hub with his divine sense. Each pattern was extremely fine, and the trajectories of the paths of different spiritual powers were all consistent with the records in the big array jade slip. Mo Hua was still uneasy and checked it several times from beginning to end, then lightly breathed a sigh of relief. Success! Mo Hua looked at the profound and complex array hub in front of him, and a feeling of joy arose spontaneously. The structure of the array hub was rigorous, accumulating fine strokes into heavy edges, having a kind of complex and profound beauty. The only regret was that it was Mo Hua’s first time drawing the array hub on an array disk, and his pen technique was not skilled, and he had erased it quite a few times, so it didn’t look too aesthetic. Although it wasn’t too aesthetic, as long as it could be used, it was fine! Mo Hua felt that for cultivators, practicality was more important, practicality was better than anything.

When the array hub was finished drawing, Master Luo led the other array masters in. Seeing the scene in front of them, everyone’s hearts and spirits were involuntarily shocked. This is the array hub of a big array… The complex patterns were intimidating to look at, and at first glance, it was clear that they could not learn them… Master Luo, after sighing, observed the array hub for a long time. On the one hand, he was shocked that the array formation attainment of this “high person” was superb, and he could actually really draw out the array hub of a big array; on the other hand, he had doubts in his heart, how could the pen technique of this “high person” look a bit unskilled, like a child’s scribbling, having been erased so many times…
