Breaking the Restriction and Obtaining the Immortal Herb

Hu Shu stared at the Restriction, his mind rapidly recalling knowledge about ancient spells from the Invincible Domain System. He knew time was of the essence; the Human Race was waiting for him to return with the Immortal Herb. After a moment, a resolute glint flashed in his eyes. He raised his hand and reached towards the Restriction, preparing to attempt a breakthrough for the first time. The instant his hand touched the Restriction, a powerful force repelled him, causing Hu Shu to stumble back a few steps. However, he showed no signs of retreat and resolutely walked towards the Restriction again.

A biting cold wind howled outside the ice cave, its sharp sound like wailing ghosts, as if trying to blow away Hu Shu's resolve. The ice cave emanated a faint blue light, contrasting with the surrounding white snow, making it appear mysterious and eerie. Hu Shu took a deep breath, forcing himself to calm down. His gaze moved inch by inch over the Restriction, trying to find a flaw in its complex patterns and flickering light.

"This Restriction..." Hu Shu muttered, his brow furrowed. He realized it was indeed an extremely ancient sealing spell, its structure complex and imbued with unique Rune laws. These Runes intertwined, forming a tight defensive system that ordinary methods of breaking it could not overcome.

Hu Shu closed his eyes, searching his mind again for knowledge within the Invincible Domain System. He remembered browsing an entry about ancient sealing spells in the system, which mentioned similar Restrictions. Perhaps he could find inspiration there.

After a moment of thought, Hu Shu rapidly formed hand seals, chanting words under his breath. Golden light streamed from his fingertips, flying towards the Restriction. As the light touched the Restriction, it emitted a "sizzling" sound, like hot oil dripping into water. However, the Restriction merely trembled slightly before returning to its calm state.

Hu Shu was not discouraged. He tried several other methods, either striking with Spiritual Power or attempting to penetrate with mental energy, but the Restriction blocked them all. With each failed attempt, Hu Shu's face grew paler, and the consumption of his magic left him feeling somewhat powerless.

"Is there no other way?" Hu Shu gritted his teeth, a surge of unwillingness rising within him. He looked up towards the depths of the ice cave. The strange light emanating from the Immortal Herb seemed to be calling to him, while also reminding him of the Human Race's current crisis.

Just as Hu Shu felt at a loss, he suddenly noticed that the frequency of the Runes' flickering on the Restriction seemed to follow a pattern. His heart stirred, and he observed it more closely. After some study, he discovered that the flickering of these Runes coincided with a certain ancient rhythm.

"That's it! Perhaps I can break it by following this rhythm!" A flash of excitement lit up Hu Shu's eyes. He focused his mind, adjusting his Spiritual Power output frequency according to the rhythm of the Runes' flickering.

Hu Shu formed hand seals again, this time his movements slower and steadier. His Spiritual Power, like threads, extended towards the Restriction. When the Spiritual Power came into contact with the Restriction, it was no longer a fierce collision as before, but a slow infiltration following the rhythm of the Runes.

As the Spiritual Power continued to penetrate, the Restriction began to show noticeable changes. Its originally solid light became somewhat wavering, and the flickering of the Runes grew more rapid. Seeing this, Hu Shu was overjoyed and increased his Spiritual Power output.

"Boom!" Finally, through Hu Shu's unremitting efforts, the Restriction let out a loud roar, and a crack appeared on its surface. Immediately, the crack spread rapidly, and the entire Restriction shattered with a bang.

Hu Shu let out a long sigh, wiped the sweat from his forehead, and stepped into the ice cave. Inside, the cold air rushed towards him, like countless tiny ice needles pricking his skin. The cave was carved from ice and jade, with various strangely shaped ice pillars and ice flowers standing tall. Under the illumination of the Immortal Herb's light, it was dreamlike and fantastical.

The Immortal Herb grew in the center of the ice cave. It was verdant green all over, its leaves shimmering with crystalline dew, emitting a fresh and rich fragrance that was invigorating. Hu Shu quickly walked to the Immortal Herb, carefully plucked it, and placed it in a specially made jade box.

After securing the Immortal Herb, Hu Shu dared not delay for a moment. He hurried towards the Human Race settlement. His figure was like lightning as he darted through the icy landscape, his heart filled with worry for the people of the Human Race.

At the Human Race settlement, the atmosphere was somewhat oppressive. Some members of the Human Race were still lying in their beds, their breaths weak. Others stood guard nearby, their eyes filled with anxiety and anticipation.

"Why hasn't Lord Hu Shu returned yet? Everyone is almost at their limit..." a young Human Race man said worriedly.

"Don't talk nonsense. Lord Hu Shu will definitely return with the Immortal Herb to save us!" an elder glared at the young man and said firmly.

However, behind this seemingly calm wait, a crisis was quietly approaching.

Hu Shu, on his way back, had no idea that during his absence, the Human Race settlement was about to face a new upheaval.
