Chapter 443: Yin-Yang Mutual Aid, Dual-Core Resonance

Yage seemed to have sensed a threat. Its massive Void entity accelerated its condensation, gradually shifting from a blurred outline to something clear and concrete. At the same time, countless purple-black tentacles extended from within its body, writhing and twisting like living things, launching violent attacks toward the headquarters and various energy nodes across the globe.

"Increase defense system power to maximum!" Xu Feng commanded the technical team to adjust the parameters, "Concentrate energy, prioritize protecting the Five Cores and Lin Xuan!"

Despite the defense system operating at full capacity, several purple-black tentacles broke through the barrier and struck Lin Xuan directly. Lin Xuan let out a muffled groan of pain, his body trembling violently, and the flow of energy immediately became chaotic. The five-colored light flickered, and the positions of the Five Cores began to deviate from their preset orbits.

"Oh no!" Xu Feng's expression changed drastically, "Lin Xuan's Spirit Body has been damaged again, the energy flow is out of control!"

Monitoring equipment showed that the connection between Lin Xuan's Spirit Body and his physical body had dropped to a dangerous level and could completely sever at any moment. The Energy Network became turbulent as a result, and the connections between the Five Major Cultivation Centers across the globe became unstable.

Xiao Yuan stood to the side, watching Lin Xuan struggle in pain, her heart feeling as if it were being twisted. She had wanted to share some of the pressure through the Energy Diversion Device, but Yage's attacks were too fierce; the device alone could no longer cope.

"No, if this continues, Lin Xuan won't be able to hold on!" A flash of determination crossed Xiao Yuan's eyes, "I must... enter the fray myself!"

Ignoring Xu Feng's attempts to stop her, Xiao Yuan rushed into the energy field without hesitation. The terrifying energy impact made her almost unable to stand, but she gritted her teeth and persisted, moving closer to Lin Xuan step by step.

"Xiao Yuan! Come back! It's too dangerous!" Xu Feng shouted, but it was already too late.

Xiao Yuan finally reached Lin Xuan and grabbed his hands without hesitation. In an instant, an unprecedented, excruciating pain spread through her entire body; she felt as if her soul were being torn apart, yet she still gripped Lin Xuan's hands tightly, refusing to let go.

"Xiao Yuan..." Lin Xuan opened his eyes with difficulty, seeing the person before him, "You... go away... it's too dangerous..."

"No!" Xiao Yuan shook her head firmly, "I won't leave you to fight alone! We'll do it together, Lin Xuan, we'll face it together!"

Just then, a shocking scene occurred. Where Xiao Yuan and Lin Xuan made contact, the previously chaotic five-colored energy suddenly became exceptionally stable, and the light grew brighter and softer. A special energy resonance began to form between the two, gradually spreading throughout the entire energy field.

"This is... Yin-Yang Mutual Aid?" Xu Feng looked at the scene before him in disbelief, then suddenly realized, "The Dual-Core Resonance predicted by Yang Zhiyuan!"

Everyone watched this scene in astonishment. As Practitioners of Yin-Yang Dual Cultivation, a unique energy resonance had formed between Lin Xuan and Xiao Yuan. Lin Xuan focused on the power of Yang, while Xiao Yuan focused on the power of Yin; the two energies complemented each other perfectly, forming a small, naturally balanced circulatory system.

As the two energies merged, the operation of the Five Elements Core became even smoother. The previously wavering cores returned to their preset orbits, and the five-colored light stabilized once more. The entire Energy Network resumed normal operation, becoming even stronger than before.

Yage seemed to perceive the danger brought by this change. Its attacks became even more frantic, with almost all its power concentrated on Lin Xuan and Xiao Yuan. Countless purple-black tentacles fell like rain, attempting to interrupt this dangerous resonance.

At this critical moment, Practitioners across the globe simultaneously unleashed the strongest secret arts of their respective systems.

In the Beijing Forbidden City, Zhang Qingsong led the Daoist cultivators in forming a special hand seal, guiding the pure Taiji Power: "Taiji Yin-Yang Great Transformation!" A massive Taiji Pattern formed above the Forbidden City, rotating continuously and releasing a powerful force of balance.

At the summit of Mount Fuji, Yamada Ichiro raised the ancestral Yata Mirror, the surface reflecting a mysterious light: "Yata Mirror: Amaterasu Reflection!" A beam of pure golden light shot from the mirror, purifying the pollution of the Void.

At the Ganges Source, Lakshmi led the Yogis in performing the highest secret rite: "Great Sun Tathagata Vajradhatu Mandala!" A massive Mandala pattern unfolded in the sky, releasing the supreme power of the Buddha Sect.

Practitioners in Europe and Africa also unleashed their strongest secret arts; energies from five different systems traversed space and converged at the headquarters, forming a five-colored light shield that surrounded Lin Xuan and Xiao Yuan, resisting Yage's fierce attacks.

Protected by this light shield, Lin Xuan and Xiao Yuan were able to guide the energy with all their might. Their consciousnesses seemed to reach a marvelous resonance, even allowing them to communicate directly.

"Xiao Yuan, follow my lead," Lin Xuan's voice rang directly in Xiao Yuan's mind, "We need to readjust the flow of the Five Elements Energy."

Xiao Yuan nodded, cooperating fully with Lin Xuan's guidance. Under their control, the Five Cores formed a more complex energy circulation pattern. The Five Elements generated and restrained each other in a continuous cycle, and each cycle produced even purer, more powerful energy.

This energy began to strike Yage's main body, and fine cracks appeared on the surface of the purple-black Void entity. Yage's attacks weakened slightly as a result, but its body continued to solidify, having already completed 90% of its descent.

"Keep going!" Lin Xuan encouraged Xiao Yuan in his consciousness, "We are gaining the advantage!"

However, at this moment, Yage made an unexpected move. It stopped attacking the headquarters, and all its tentacles retracted into its body. Immediately after, its body began to expand rapidly, releasing Void Energy several times more powerful than before, forming a massive energy field to contend with the Energy Network constructed by humanity.

The energy fields of both sides collided in mid-air, forming a massive energy vortex. At the center of the vortex, purple-black and five-colored energies intertwined, neither side able to completely suppress the other. This war of energy attrition fell into a stalemate, a test of who could hold out until the end.

Lin Xuan and Xiao Yuan felt immense pressure. Despite the Dual-Core Resonance, Yage's power was simply too great. Both of their Spirit Bodies began to sustain slight damage, but neither had any intention of backing down.

"We must hold on," Lin Xuan's voice rang in Xiao Yuan's mind, "Yage is exhausting its own energy; as long as we can hold out long enough, victory will be ours."

Xiao Yuan gripped Lin Xuan's hand tightly, her eyes full of determination: "I will stay with you until the very end."

Xu Feng stood before the console, closely monitoring the energy changes. Although both sides were in a stalemate, he could feel that the human side's energy was more stable and enduring. Yage's energy, while powerful, possessed a quality of impatience and instability.

"Maintain the current status," Xu Feng issued instructions to the Global Cultivation Center, "Everyone conserve energy and prepare for a long-term battle. This war of attrition may last a long time; whoever can hold out until the end will be the winner."
