Chen Xiaojun glanced at Yang Zhicheng and Ma Zhibin and continued, "When Second Uncle deduced this formation, he had already taken into account the characteristics of each family's martial soul."

"The Ma family's Nine Heavens Phoenix has three powerful natal flames. The Flame of Destruction needs to be nourished by the vast energy of destruction, the Pure Glazed Flame needs to be tempered by the pure Yin energy, and even Uncle Zhibin's Southern Brightness Flame needs the firewood of malevolence and destruction."

"The Yang Family Seven-Skill Bow is a heavy weapon on the battlefield. Every arrow it shoots is stained with blood. In the past, it required fierce energy and malevolent spirit to hone its sharpness. Now, by studying the way of Yin and Yang and the Five Elements, one can try to draw upon the pure Yin and Yang energies transformed by the magic array to broaden the path of cultivation."

"The negative energy gathered and transformed by this formation can be used by all parties, and even all the Soul Masters under our command can take it as needed."

Indeed, Qin Luguang, Zuo Jinhua, and even Xia Yun were all useful.

Ma Zhibin slapped his thigh, his eyes gleaming, his face beaming with undisguised delight: "Good heavens! Xiao Jun, your magic array is truly 'all-encompassing'! It can absorb and use any kind of energy? It's practically a treasure tailor-made for us!"

Chen Xiaojun's lips curled up slightly, with a hint of helplessness in his smile: "Uncle Zhibin, you flatter me. This formation can only draw in 'negative energy'; other forms of spiritual energy are not included."

"That's all?" Ma Zhibin's eyes widened dramatically, his mind churning. He couldn't help but mutter to himself, "To be able to manipulate so much deadly 'qi' so easily, the word 'that' sounds truly terrifying!"

Chen Xiaojun played a tiny role in the creation of this formation.

Four years ago, after Chen Xiaojun awakened his second martial soul, the Seven Kill Sword of the Underworld Sea, he tested it with the Seven Kill Concealing Qi Technique.

The result was shocking: the mysterious and unpredictable Netherworld Killing Sword not only devoured killing intent and evil energy like a whale swallowing the sea, but also strangely attracted and absorbed several kinds of negative energy of different colors and properties!
It was precisely based on the valuable "experimental data" provided by Chen Xiaojun's unique martial soul characteristics that Chen Cong was able to break through the bottleneck. He not only improved the Seven Killings Qi Condensation Technique passed down by the Chen family for thousands of years, but also perfected the concept of the Qi Absorption Array, giving it the extraordinary ability to absorb and transform various negative energies!

"Uncle Jinhua," Chen Xiaojun said no more, turning to Jinhua behind him, "please fetch a detailed layout map of the mountain fortress."

"Yes, young master!" Zuo Jinhua responded, immediately taking out a finely drawn parchment scroll from his personal storage soul tool and slowly unfolding it on the table.

As the newly appointed commander of the Ironjaw Fortress garrison, he had already memorized every inch of the fortress in the past few days.

Chen Xiaojun's slender fingers landed on the huge diagram of the evil-absorbing formation, pointing to the nine core areas marked with mysterious vortex patterns: "Please look, everyone. This formation has nine 'Nine Yin Returning to Origin' nodes, which are the source of the negative energy and also the nine sub-formation eyes, arranged according to the nine palaces."

"The nodes will be connected by a network of guiding runes, which will gradually gather and purify all the negative energies, such as violent resentment and bloody evil energy, remaining within the entire Ironjaw Fortress area."

He paused, his fingertip tracing an invisible path on the drawing: "Part of the purified energy can be further refined into an extremely refined, almost primordial 'sharp' killing force. This power will be sealed within a specially made soul-guiding container."

"In the future, under absolutely controllable conditions, elite disciples from various families who are proficient in the art of killing or possess specific dark-elemental or negative-attribute martial souls can use this to stimulate their cultivation, break through bottlenecks, or briefly unleash their potential in critical moments to turn the tide of battle!" Then, his finger moved to the Ironjaw Fortress layout map spread out by Zuo Jinhua, and he emphasized several key locations: "Taking advantage of this opportunity for post-war reconstruction, we can select these nine locations within the city to establish the Fiend Absorption Nodes."

"For example, at the main entrance, people gather, emotions are mixed, and the negative energy is most noticeable; the Soul Arena, a place of fierce battles, is naturally filled with murderous and violent energy; the taverns and gambling dens are filled with intertwined desires and resentment; in this underground city, it can be said that there is no end to the resources."

"There's also the City Lord's Mansion area where our central hub is located, and the 'Negative Martial Soul Training Base' that we just agreed on... These places are all excellent choices for setting up nodes."

He raised his head and glanced at everyone: "The energy transmission channels between nodes, as well as the energy transmission channels from nodes to the final main array eye, will be laid using soul guide tubes made of special energy-conducting materials such as mithril mixed with dark patterned steel and sunken star sand. These tubes, like veins, will continuously transport the absorbed and purified negative energy to the core container of the main array eye."

"The cost, the resources required, and the time spent are considerable."

"Mithril?!" Qin Luguang's eyes lit up, and his face showed surprise. "Isn't this the associated mineral that was just discovered in our Ironjaw Fortress mine? The reserves seem to be quite large!"

“Exactly!” Chen Xiaojun nodded affirmatively, a wry smile appearing on his face. “That’s why I said this might be fate’s arrangement. Mithril has excellent conductivity and is one of the core materials for constructing high-level soul tools, making it priceless.”

"Our capture of Ironjaw Fortress has given us access to these invaluable resources; it's a godsend, and we've seized this opportunity!"

Yang Zhicheng's steady voice rang out: "This formation is ingeniously designed, but its core lies in the array core, especially the main array core of the main array eye. It needs to contain, transform, and store so many different kinds and such a vast amount of negative energy, so the material requirements must be extremely demanding. Xiao Jun, is there any progress on this?"

Chen Xiaojun smiled slightly, without answering directly, but calmly took out an exquisite treasure box carved from warm jade from his storage soul tool.

The moment the box was opened, an indescribable aura brimming with vitality filled the air, instantly dispelling the slightly somber atmosphere in the council hall caused by the discussion of negativity.

Inside the box lay a gemstone about the size of a pebble.

Its entire body presents a deep and warm green color, and on this rich green base, there is a strange flow of beautiful red and blue light, like water waves and flames coexisting harmoniously.

The gemstone's irregular shape gives it a sense of natural perfection, exuding an indescribable, vibrant yet all-encompassing charm. It possesses both the gentle nourishment of water and the vigorous passion of fire.

"The Heart of the Divine Tree!" Qin Luguang, Zhu Yanfeng, and Yang Zhicheng exclaimed almost simultaneously.

Ximen Wenye and Chen Zhang exchanged a glance. The old poplar tree of the Yang family was the one-foot-sized divine tree heart that broke through to become a 100,000-year-old soul beast.

The Heart of the Sacred Tree!

It contains the power of life's origin, and because it has undergone countless years of baptism by the Yin and Yang of ice and fire during its growth process, it naturally possesses the characteristics of harmonizing Yin and Yang and bearing all things!
Uh, a jack-of-all-trades.
