Chapter One Hundred and Twenty-Three: Tech Casts a Shield to Block the Demon Tide, Surviving Stragglers Reveal Secrets

The cold wind of the Northern Border carried the scent of blood as it swept across the frozen border line.

The emergency passage of the Huaxia Outpost had just opened, and the last few Bear Country survivors stumbled in. The Hell Envoys behind them had already closed in to within a hundred meters. They spread their bone wings, their crimson vertical pupils locked onto the passage entrance, and the dark purple energy fluctuations on their bone swords grew increasingly violent, clearly preparing to break into Huaxia territory before the passage closed.

"Close the passage! Activate level two defense!" the outpost commander roared as he pressed the button. The alloy gate slowly descended, and the Magnetic Storm Power Grid lit up again with faint blue arcs.

But at the very moment the Hell Envoy's bone sword was about to touch the gate, a sudden change occurred.

A soft yet incredibly brilliant golden radiance suddenly gushed out from beneath the Huaxia border line, like the rising sun at dawn, instantly enveloping the entire border area. Wherever the radiance reached, the dark purple mist melted away as quickly as snow meeting fire. The scales on the Hell Envoys began to emit a "sizzling" burning sound, and their originally violent energy fluctuations abruptly weakened.

"What is that?!" Whether it was the Huaxia soldiers, the Bear Country survivors, or the approaching Hell Envoys, everyone was stunned by this sudden golden radiance.

The golden radiance condensed into a translucent light screen on the border line. Upon the screen, intricate energy patterns faintly emerged—those were the Magnetic Storm Resonance Runes unique to red alert technology. As they flowed, they emitted a purifying aura specifically targeting dark matter energy. The Hell Envoys tried to break through the light screen, their bone swords and sharp claws striking the radiance simultaneously, only to be knocked back repeatedly by the golden energy rebounding from the screen. Their scales shattered, and dark purple blood spurted out.

"Anti... Anti-matter Purification Energy?" The Hell Envoy's raspy voice echoed in everyone's minds, filled with unprecedented wariness and rage. "How could humans... master such power?"

They paced unwillingly outside the light screen, their bone wings flapping as dark purple energy continuously struck the radiance, yet they remained unable to budge it in the slightest. The energy patterns on the light screen grew brighter, and the golden energy spread out in waves like a tide, purifying all the dark purple venom and mutated plants near the border line, revealing the original soil.

Inside the outpost, the Bear Country survivors widened their eyes, their faces filled with unbelievable shock. They had never seen such powerful defensive technology that could suppress these demon-like invaders with absolute advantage. "Is this... Huaxia's new weapon?" a survivor murmured, eyes filled with the relief and awe of having survived a disaster.

The transport plane Lin Zhou was on happened to arrive over the Northern Border. Through the window, he saw the golden light screen on the border line, and his tense nerves finally relaxed slightly—this was exactly the "Ultimate Purification Shield" that the red alert Research Team had spent three months of hard work secretly developing. He hadn't expected it to play a role at such a critical moment.

"Connect to the Research Center immediately and inquire about the shield's operational status!" Lin Zhou ordered into the communicator. "Also, tell the outpost to stay on alert and closely monitor the Hell Envoys' movements. Report immediately if they show any signs of retreating!"

The transport plane landed at a temporary airport near the outpost. Lin Zhou stepped off the plane quickly and headed straight for the outpost's command room. Inside, researchers were synchronizing the shield's monitoring data in real-time. The screen showed that the shield's energy output was stable, and the core resonance frequency formed a perfect offset against the Hell Envoys' dark matter energy, with a purification efficiency reaching 98%.

"commander, the Ultimate Purification Shield did not disappoint!" The Research Team Leader's voice carried uncontrollable excitement. "This is an ultimate defensive weapon we developed by combining magnetic storm energy, anti-resonance technology, and purification genes extracted from God Devourer larvae. It can actively identify dark matter energy signatures and decompose and purify them through high-frequency resonance, specifically countering alien evil creatures like the Hell Envoys. We have deployed shield generators across the three major defense lines of the Northern Border, Southwest, and East Sea. Just now, the highest defense mode was automatically triggered!"

Lin Zhou nodded, a hint of approval flashing in his eyes. The wisdom of red alert scientists always brought hope in humanity's most desperate moments. His gaze turned to the Bear Country survivors being housed in the medical area. One of them, an old man in a white coat covered in injuries, caught his attention—a Bear Country Academy of Sciences badge was pinned to the old man's chest, and though his eyes showed exhaustion, they held a trace of determination.

"Who is he?" Lin Zhou asked.

The outpost commander replied, "He is Professor Ivanov, the chief physicist of the Bear Country's Siberian Branch. According to other survivors, he has been studying the meteorite that fell in the Amazon three months ago. During this Hell Envoy raid, he was specifically protected and brought out by a winter war god mecha."

Lin Zhou's heart stirred, and he immediately walked toward the medical area. Seeing Lin Zhou, Professor Ivanov struggled to get up, but Lin Zhou held him down. "Professor, there's no need for formalities," Lin Zhou said in a deep voice. "We need your help. Regarding the Hell Envoys and that meteorite, you must know something."

Professor Ivanov nodded, a flash of grief in his eyes. "Yes, I have been studying that meteorite for three months. It is no ordinary meteorite; it is the key to a 'Hell's Gate' from an evil dimension called the 'Abyss Demonic Realm.' The Hell Envoys descended upon Earth through the spatial rift opened by that meteorite."

He paused and continued, "These demons feed on life energy. Their goal is to devour the life energy of the entire Earth and open a larger spatial rift to allow more abyss demons to descend. The reason Bear Country's defense lines collapsed so quickly is that they possess 'Spatial Anchor' technology, which allows them to precisely locate weak defense areas for instantaneous raids."

"Then what is their weakness?" Lin Zhou asked urgently.

"Their weakness is the purification energy contained in your shield." Professor Ivanov looked at the golden light screen outside the window, a glimmer of hope in his eyes. "The demons of the Abyss Demonic Realm are composed of dark matter energy; once they encounter high-intensity purification energy, their structure will collapse. But I'm not sure how long this shield can last. The Hell Envoys will surely find a way to adjust their energy frequency to crack the defense. Furthermore, hidden at the core of the Amazon rainforest meteorite is an 'abyss core.' That is the key to maintaining the spatial rift. As long as it is destroyed, the Hell Envoys will be unable to obtain energy supplies, and the spatial rift will close automatically."

A sharp light instantly ignited in Lin Zhou's eyes. He immediately ordered into the communicator, "Notify the Amazon stay-behind squad to immediately head deep into the meteorite's core area to find and destroy the abyss core! Research Team, combine the data provided by Professor Ivanov to optimize the Ultimate Purification Shield's energy frequency. Simultaneously, integrate purification energy into the Star Core Demon-Breaking Cannon to develop 'Purification Demon-Breaking Shells' that can actively attack! Northern Border troops, hold the line and closely monitor the Hell Envoys' energy fluctuations. If they attempt to adjust their frequency to crack the shield, use the Railguns to interfere immediately!"

The orders were issued, and all units moved quickly. The stay-behind squad in the Amazon rainforest, under the cover of the Star Core Interference Cannons, quietly advanced toward the meteorite's core area. The Ultimate Purification Shield and the magnetic storm defense belt in the Northern Border formed a double layer of protection. Soldiers stood ready, staring at the Hell Envoys pacing outside the light screen. In the Research Center, scientists worked side-by-side with Professor Ivanov, racing against time to optimize technology and develop new weapons.

Outside the light screen, the Hell Envoys' patience was gradually wearing thin. The leading Hell Envoy raised its bone sword, and dark purple energy surged violently on the blade. It was clearly adjusting its energy frequency, attempting to break through the shield. It swung the bone sword down fiercely, and a blade of energy condensed from pure dark matter energy slashed toward the golden light screen.

The energy blade collided with the light screen, producing a deafening roar. The golden light screen flickered violently, and the flow of energy patterns instantly accelerated, barely managing to decompose and purify the energy blade, but the shield's energy reading still dropped by 5%.

"They are adjusting their energy frequency!" the outpost observer shouted.

"Activate magnetic storm interference immediately!" Lin Zhou ordered.

The Railguns on the border line fired simultaneously, and blue magnetic storm energy beams shot toward the Hell Envoys' energy field, disrupting their energy resonance rhythm. The Hell Envoys' second attack instantly lost control, and the energy blade exploded in mid-air, instead injuring the surrounding companions.

Lin Zhou clenched his fists, knowing clearly that this contest between technology and evil had only just entered its white-hot stage. The appearance of the Ultimate Purification Shield had bought precious breathing time for humanity, but the Hell Envoys' attempts to crack it never stopped. The mission to destroy the abyss core in the Amazon, the development of the Purification Demon-Breaking Shells, and the continuous optimization of the shield's energy—every single task concerned the survival of humanity.

Meanwhile, at the core of the Amazon rainforest meteorite, the dark purple spatial rift was continuously expanding. More Hell Envoys were stepping out from the rift. Their leader—a giant demon surrounded by black flames and holding a Dark Crystal Scepter—was coldly watching the direction of the Northern Border, a desire for destruction flickering in its crimson eyes.
