Desperate Survival, System Activation

The roaring sound made everyone's eardrums ache, and the ground trembled more violently. Hu Shu looked at the distant, dust-filled horizon, his heart pounding. Suddenly, a mysterious light erupted from within him, instantly enveloping his surroundings. A cold, mechanical voice sounded in his mind: "Invincible Domain System activated..." This sudden change surprised and delighted Hu Shu. However, he knew deep down that the road ahead was still full of unknowns.

Hu Shu's gaze frantically swept over every corner of Shouyang Mountain. That powerful aura was drawing closer like a dark cloud threatening to engulf the entire Human Race settlement at any moment. He was burning with anxiety, the terrified faces of the Human Race people flashing before his eyes. If he didn't act now, the Human Race would surely be annihilated here.

His feet ran back and forth on the rugged mountain path, his eyes urgently searching the forests, rocks, and sky, trying to find even a sliver of a solution. The wind howled past his ears like a prelude to death. The sounds of Witches and Demons fighting in the distance grew fiercer, as if urging on the doom of the Human Race. Hu Shu's breathing was rapid and heavy, each inhale filled with tension and anxiety. Sweat soaked his clothes, yet he was oblivious.

At this critical juncture, a flash of inspiration suddenly struck Hu Shu's mind. He remembered that when he transmigrated, he seemed to have brought some kind of mysterious power with him, but he had never noticed it before. With the mindset of a desperate gamble, Hu Shu concentrated all his mental energy, trying to explore the power hidden within his body.

In an instant, an even more dazzling mysterious light burst forth from his body. The light spread rapidly like a tangible substance, covering a three-thousand-mile radius around Shouyang Mountain in the blink of an eye. Wherever the light reached, the earth, which had been trembling from the Witches and Demons' battle, instantly calmed down. The wind stopped abruptly, and even the clamor of the Witches and Demons fighting in the distance seemed to be shut out.

At the same time, a cold, mechanical voice sounded clearly in Hu Shu's mind: "Invincible Domain System activated. The host is invincible within the domain. The current domain covers a three-thousand-mile radius of Human Race's Shouyang Mountain and can move with the host's will. The domain can be upgraded by completing system tasks, helping the Human Race overcome tribulations, and other methods."

Hu Shu's eyes widened, filled with surprise and disbelief. This sudden system was like a ray of dawn in the darkness, giving him hope to save the Human Race. He looked up at the area covered by the light, feeling the mysterious and powerful energy within it, and a sense of confidence he had never felt before surged within him.

The despair in the eyes of the Human Race people now flickered with a sliver of hope. They looked at the mysterious light enveloping Shouyang Mountain, as if seeing an indestructible barrier. Some began to whisper prayers, while others gathered around Hu Shu, their eyes filled with admiration and anticipation.

Hu Shu took a deep breath, trying to calm his excited emotions. Although the system's activation granted him invincible power within the domain, he knew clearly that this was only the beginning. He knew almost nothing about this system. How to use the system's power to save the Human Race, how to lead the Human Race step by step towards strength in this perilous Primordial World – these questions weighed on his heart like heavy stones.

Hu Shu looked down at the ground beneath his feet. The outline of the Human Race settlement was clearly visible under the light. He clenched his fists tightly, his gaze becoming resolute. No matter how many difficulties and dangers lay ahead, since Heaven had bestowed this system upon him, he would definitely shoulder the responsibility of protecting the Human Race.

At this moment, Shouyang Mountain was silent, with only the mysterious light slowly flowing. Hu Shu stood within the light, but his thoughts had already drifted to the distance, contemplating the next course of action. Behind him, the Human Race people waited quietly, placing all their hopes on Hu Shu.
