Sudden Attack Arrives, Full Resistance

Hu Shu's expression drastically changed upon hearing the rumbling sounds from the foot of the mountain. He rushed out of the cave and saw flames soaring into the sky below Shouyang Mountain, with shouts of killing deafening. "Not good, it's an attack from the Heavenly Origin Sect and the Demon Race!" Hu Shu cursed inwardly. He turned and shouted to the Mysterious Rogue Cultivator inside the cave, "Senior, we're under attack! We need to quickly organize the Human Race to resist!" With that, his figure flickered, and he dashed towards the center of the Human Race settlement, preparing to activate his Invincible Domain and face this battle for survival.

At this moment, below Shouyang Mountain, the combined army of the Heavenly Origin Sect and the Demon Race surged forward like a black tide. The Golden Immortals of the Heavenly Origin Sect, clad in Daoist robes and wielding Magic Treasures, had stern expressions. Powerful spells poured from their hands, directly targeting the Human Race settlement. Meanwhile, the experts of the Demon Race varied in form, some with human bodies and beast heads, others transforming into massive Demonic Beasts, charging towards the Human Race defense line with bared fangs and claws.

Hu Shu arrived at the center of the settlement, his hands forming seals rapidly as he chanted incantations. Instantly, a transparent barrier of light spread out from him, his Invincible Domain. Wherever the domain reached, the Human Race felt a powerful force enveloping them, their fear instantly lessening. "Everyone, don't panic! Follow my command!" Hu Shu shouted loudly, his voice echoing within the domain.

The Human Race quickly took their positions according to Hu Shu's prior arrangements. The young and strong took up weapons, guarding key points of the Defensive Formation, while the old, weak, women, and children hid in the rear, providing logistical support for the warriors in front. Hu Shu felt a slight relief seeing the orderly Human Race, but he knew the upcoming battle would be exceptionally difficult.

The Golden Immortals of the Heavenly Origin Sect's expressions shifted slightly upon seeing the Invincible Domain activated. One Golden Immortal snorted, "This Hu Shu indeed has some tricks up his sleeve, but today will be the end for him and the Human Race!" With that, he waved his whisk, and a golden light shot out like a sharp sword towards the Invincible Domain. The light struck the domain's barrier, causing ripples and making the barrier tremble slightly. Seeing this, the other Golden Immortals unleashed their spells, and for a time, various colored lights intertwined, constantly assaulting the Invincible Domain.

The experts of the Demon Race were not to be outdone. They roared, using their powerful physiques to charge directly at the domain's defenses. Each impact caused the domain's barrier to shake violently. Some enormous Demonic Beasts even used their sharp claws and teeth to try and tear through the barrier.

Hu Shu stood at the center of the domain, doing his utmost to maintain its stability. He could feel the pressure on the domain increasing with every attack from the Golden Immortals and the Demon Race experts. Sweat dripped from his forehead, but his gaze was incredibly resolute. "Everyone, hold steady! We can defend this!" Hu Shu shouted to boost morale.

Inspired by Hu Shu, the Human Race erupted with unprecedented fighting spirit. They controlled the Defensive Formation, and beams of Spiritual Power shot out from it, attacking the incoming enemies. The newly forged Magic Treasures also proved their worth, emitting rays of light that inflicted some damage on the Demon Race experts.

The Mysterious Rogue Cultivator also arrived on the battlefield. He moved his hands, chanting obscure incantations. Dark clouds suddenly appeared in the sky, flashing with purple lightning. The lightning descended like dragons, striking towards the Golden Immortals and the Demon Race experts. This sudden attack threw the enemy into disarray. Some of the weaker Demon Race experts were directly hit by the lightning, letting out painful roars.

The Golden Immortals of the Heavenly Origin Sect quickly adjusted, joining forces to cast a massive shield, protecting themselves and some of the Demon Race experts. Lightning struck the shield, creating countless sparks but failing to break through the defense.

The Demon Race experts seized the opportunity to charge again. This time, their attacks were even fiercer. A massive White Tiger Demon, radiating white light, leaped forward and slammed into the Invincible Domain. The force of this blow was incredibly powerful, causing numerous fine cracks to appear on the domain's barrier.

Hu Shu was greatly alarmed. He knew that if the Invincible Domain was breached, the Human Race would face annihilation. Gritting his teeth, he poured all his Spiritual Power into the domain, attempting to repair the cracks on the barrier.

Seeing Hu Shu's desperate efforts, the Human Race also gave their all. They channeled their Spiritual Power into the Defensive Formation, which then shone brightly, launching a counterattack against the enemies.

However, the combined attack of the Heavenly Origin Sect and the Demon Race was too powerful. Under the continuous assault, the Invincible Domain's barrier developed more and more cracks, becoming precarious. Despite the Human Race's desperate resistance, the situation remained critical.

Hu Shu gazed at the faltering Invincible Domain, his mind racing for a solution. His eyes quickly scanned the battlefield, searching for the enemy's weaknesses. At this moment, he noticed some flaws in the coordination of the Demon Race experts as they charged. Furthermore, the Golden Immortals of the Heavenly Origin Sect had consumed a considerable amount of Spiritual Power to maintain their shield.

A thought struck Hu Shu, and he quickly shouted to the Human Race, "Concentrate your attacks on the Demon Race's left flank! Disrupt their formation!" Hearing this, the Human Race immediately controlled the Defensive Formation and Magic Treasures, focusing their attacks on the Demon Race's left flank. For a time, the Demon Race experts on the left flank were engulfed by the powerful attacks, and screams filled the air.

The Demon Race's formation began to break down, their previously tight attack rhythm disrupted. The Golden Immortals of the Heavenly Origin Sect, seeing this, had to divert some of their Spiritual Power to help the Demon Race stabilize their formation.

Just then, a deep thunderclap echoed from the sky. Hu Shu's heart leaped with joy, knowing that the Mysterious Rogue Cultivator was unleashing another powerful spell. The dark clouds in the sky rapidly gathered, forming a massive vortex. Within the vortex, a thick purple lightning bolt was gestured into existence.

With a deafening "Boom!", the lightning struck the enemies like a falling meteor. This bolt of lightning was several times more powerful than the previous ones, directly shattering the Golden Immortals' shield and striking the Demonic Beasts and Golden Immortals below.

For a moment, screams filled the battlefield. The Demon Race experts suffered heavy casualties, and the Golden Immortals of the Heavenly Origin Sect also sustained injuries of varying degrees. They had never expected the Human Race to launch such a powerful counterattack in such a desperate situation.

Hu Shu seized this opportunity and increased his Spiritual Power output to the Invincible Domain. On the domain's barrier, the cracks began to heal gradually. Seeing the situation improve, the Human Race's morale soared, and their attacks became even fiercer.

However, the Heavenly Origin Sect and the Demon Race were powerful after all. After a brief period of chaos, they quickly regrouped. The Golden Immortals of the Heavenly Origin Sect unleashed a more potent combined spell. Their Magic Treasures glowed brightly, forming a complex circuit of Spiritual Power among them.

As the Golden Immortals chanted, a massive golden Rune appeared in the sky. The Rune flickered with dazzling light, emitting a power that sent shivers down one's spine. The Demon Race experts also unleashed their innate abilities, echoing the Golden Immortals' spells.

The golden Rune slowly pressed down towards the Invincible Domain. Wherever it passed, space itself seemed to distort. Hu Shu felt unprecedented pressure, his body trembling slightly, but he held firm, supporting the Invincible Domain.

The Human Race also felt this immense oppressive force, their expressions turning extremely grim. But not a single person retreated; they tightly gripped their weapons, ready to face the final onslaught.

Under the pressure of the golden Rune, the Invincible Domain emitted "cracking" sounds. Numerous cracks reappeared on the barrier, and this time they were thicker than before. Blood trickled from the corner of Hu Shu's mouth; his Spiritual Power had been depleted to its absolute limit.

Seeing this, a look of determination flashed in the Mysterious Rogue Cultivator's eyes. Disregarding his own weakness, he unleashed another spell. Rings of mysterious Runes appeared around his body, their light flashing and gradually converging into a massive shield, which moved to meet the golden Rune.

"Boom!" The shield collided with the golden Rune, erupting in a blinding flash of light. The light illuminated the entire Shouyang Mountain, and a powerful shockwave swept out, uprooting trees in its path.

Although the Mysterious Rogue Cultivator's shield successfully blocked some of the golden Rune's power, it couldn't completely negate it. The golden Rune continued to press down on the Invincible Domain, which teetered precariously, seemingly on the verge of shattering.

Under this immense pressure, the Human Race was beginning to falter. Some of their bodies started to tremble, and their weapons almost slipped from their grasp. Yet, their eyes remained resolute; they knew they could not give up at this moment.

Hu Shu looked at the determined eyes of the Human Race, a sense of tragic heroism surging within him. He secretly vowed in his heart that he would protect the Human Race, even if it cost him his last ounce of strength.

At this critical juncture, Hu Shu suddenly felt a strange power emanating from the Invincible Domain System within him. This power rapidly replenished his depleted Spiritual Power, instantly restoring a portion of his exhausted energy.

Hu Shu rejoiced, immediately channeling this power into the Invincible Domain. The domain's barrier flashed, and the seemingly shattered barrier temporarily stabilized.

But Hu Shu knew this was only temporary. The combined attack of the Heavenly Origin Sect and the Demon Race was still powerful, and he needed to find a way to resolve the crisis completely as soon as possible. His gaze swept across the battlefield, searching for the enemy's weaknesses.

At this moment, he noticed a subtle fluctuation in the Spiritual Power connection among the Golden Immortals of the Heavenly Origin Sect after they unleashed their combined spell. Although this fluctuation was extremely faint, Hu Shu's keen senses detected it.

A thought flashed through Hu Shu's mind, and he quickly shouted to the Human Race, "Listen up, everyone! Concentrate all your strength and attack the location of the Golden Immortals' Spiritual Power connection!" Hearing this, the Human Race unhesitatingly focused the attacks of the Defensive Formation and Magic Treasures in the direction Hu Shu indicated.

Beams of powerful Spiritual Power attacks shot towards the Golden Immortals of the Heavenly Origin Sect, targeting the weak point in their Spiritual Power connection. The Golden Immortals sensed the Human Race's intention and tried to adjust their Spiritual Power connection to evade the attack.

But it was too late; the Human Race's attack had arrived. The powerful Spiritual Power surge struck the connection point of the Golden Immortals, instantly causing a Spiritual Power disturbance. The Golden Immortals' combined spell developed a flaw, and the light of the golden Rune began to flicker erratically.

The Demon Race experts were shocked to see the Golden Immortals' spell falter. Their attack rhythm was also affected, becoming somewhat chaotic.

Hu Shu seized this opportunity and increased his control over the Invincible Domain. The domain's barrier shone brightly, repelling the Demon Race experts' attacks one by one.

The Mysterious Rogue Cultivator also took the opportunity to unleash another spell. His hands moved rapidly, and mysterious Runes flew from his hands towards the Golden Immortals of the Heavenly Origin Sect. The Runes struck the Golden Immortals, causing a series of explosions.

Under the combined attack of the Human Race and the Mysterious Rogue Cultivator, the Golden Immortals of the Heavenly Origin Sect fell into a predicament. Their combined spell was broken, and they themselves suffered some damage. Seeing this, the Demon Race experts began to consider retreating.

But just then, a Demon Race leader roared, "We cannot retreat! If we don't eliminate the Human Race today, they will become a great threat in the future!" Inspired by his words, the Demon Race experts rallied again and regrouped their attack with the Golden Immortals of the Heavenly Origin Sect.

Hu Shu saw the enemies launch another attack and knew that this battle was far from over. He took a deep breath and shouted to the Human Race, "Don't let your guard down! We continue to fight!" The Human Race responded in unison, their voices echoing across Shouyang Mountain.

The two sides plunged back into fierce combat, spell lights illuminating the night sky, and shouts of killing deafening. The Invincible Domain, under the enemy's assault, still teetered precariously, but the Human Race, with their tenacious will, held their ground firmly.

Hu Shu maintained the Invincible Domain while contemplating a strategy to defeat the enemy. He knew that if this continued, the Human Race would eventually be unable to hold on. He had to find a permanent solution to completely repel the enemy.

Suddenly, a flash of inspiration struck Hu Shu. He remembered the mysterious materials he had obtained from the Ancient Battlefield in the wilderness; perhaps he could use these materials to cast a powerful spell and deliver a fatal blow to the enemy.

Hu Shu quickly shared this idea with the Mysterious Rogue Cultivator. The Mysterious Rogue Cultivator nodded and said, "This method is feasible, but it will require my assistance." With that, the Mysterious Rogue Cultivator formed hand seals and channeled his Spiritual Power into Hu Shu.

Hu Shu felt the powerful Spiritual Power from the Mysterious Rogue Cultivator and was filled with gratitude. He immediately took out the mysterious materials and began to cast the spell according to the memories in his mind. Under Hu Shu's Spiritual Power, the mysterious materials began to melt, forming a peculiar Rune.

The Rune shimmered with multicolored light, emitting a powerful and mysterious energy. Hu Shu integrated the Rune into the Invincible Domain, and the domain's barrier instantly became vibrant and colorful.

As the runes integrated, the power of the Invincible Domain was greatly enhanced. The originally precarious light barrier became stable and emitted a powerful backlash.

The attacks from the Heavenly Origin Sect's Golden Immortals and the Demon Race's experts landed on the Invincible Domain, only to be reflected back by the backlash. Some weaker enemies were injured by their own attacks.

Seeing this, the enemies were greatly alarmed. They hadn't expected the Human Race to possess such a tactic. However, they had no intention of giving up and continued to launch frenzied attacks.

Hu Shu watched the enemies' frantic assault, a look of determination flashing in his eyes. He knew it was time to launch the final attack. He controlled the Invincible Domain, continuously gathering the backlash into a massive, multicolored sphere of light.

The multicolored sphere contained terrifying power, its aura distorting the surrounding space. Hu Shu shouted, "Go!" The sphere shot towards the enemies like a meteor.

As the multicolored sphere flew towards them, the enemies were filled with dread. They tried to dodge, but the sphere was too fast and covered too wide an area; there was nowhere to hide.

"Boom!" The multicolored sphere exploded in the midst of the enemy ranks, unleashing a brilliant flash of light and a shockwave. The light illuminated all of Shouyang Mountain, and the shockwave engulfed all the enemies.

For a time, the battlefield was filled with screams. The Heavenly Origin Sect's Golden Immortals and the Demon Race's experts suffered heavy casualties under the attack of the multicolored sphere. Some weaker ones were blown to smithereens, while the stronger ones were severely wounded.

Hu Shu looked at the miserable state of the enemies, but felt no joy. He knew that although this battle had achieved a temporary victory, the Human Race had also paid a heavy price. Furthermore, the Heavenly Origin Sect and the Demon Race would definitely not let this go, and the Human Race would face more crises in the future.

At this moment, the Invincible Domain, after this great battle, had become somewhat unstable. Hu Shu knew that he had to repair the domain as soon as possible, and at the same time, allow the Human Race to rest well and recover their strength.

He said to the Human Race, "You've all worked hard! Although we won this battle, we cannot let our guard down yet. Everyone, go back and rest first. I will handle the follow-up matters with the senior." The Human Race nodded in unison and, dragging their exhausted bodies, returned to their settlement.

Hu Shu and the Mysterious Rogue Cultivator looked at the devastated battlefield, their hearts filled with emotion. The Mysterious Rogue Cultivator said, "Although we repelled the enemy this time, the Human Race's situation remains difficult. What are your plans next?"

Hu Shu pondered for a moment and replied, "I plan to further enhance the strength of the Human Race and find more allies. At the same time, I will delve deeper into the Invincible Domain System to see if I can make the domain even more powerful."

The Mysterious Rogue Cultivator nodded, "Yes, it is good that you have this idea. I will continue to assist you, hoping that the Human Race can become strong as soon as possible."

Just as Hu Shu and the Mysterious Rogue Cultivator were talking, a mysterious aura suddenly appeared in the sky above Shouyang Mountain. This aura was powerful and enigmatic, giving people a sense of invisible pressure.

Hu Shu and the Mysterious Rogue Cultivator's expressions changed drastically. They looked up and saw that the sky had appeared
