High-level martial arts: Contract cashback, invincible starting from the Zerg.

The morning sun illuminated the western defense zone.

The alloy doors of the secluded training room slowly slid open to both sides, and a bone-chilling wind instantly rushed in, carrying with it the unique chilling atmosphere of the border. The wind and snow howled inside the elevator, creating a biting cold.

Chen Feng slowly walked out of the elevator.

Dressed in simple black outfits, without any cold protection or thermal insulation gear, they simply let the biting cold wind beat against their bodies.

It was already deep winter on the western front.

It is adjacent to the territory of the Purple Insect Clan, where cold winds rage year-round, the low temperature is biting, and it is also covered with the unique aura of the insect clan. If ordinary Earth-level martial artists do not wear special cold-proof equipment, their physical body will stagnate in a short time, and their combat power will drop sharply. If they stay there for a day, they may even suffer from cold-related illnesses, damaging their martial arts foundation.

However, at this moment, Chen Feng had received the power of the [Han Yue Hou] Marquis Seal, which greatly enhanced his physical strength and power. This level of cold could not cause any damage to Chen Feng's body.

Chen Feng looked at his hands and discovered that, with the power of the [Hou Seal], his hands could generate a blue power at any time, and the core of the universe was the source of this power.

A smile appeared on Chen Feng's lips as he began to walk step by step toward the western defensive wall in the distance.

......

When Chen Feng stood at the highest point of the city wall, he looked up and gazed into the distance.

At the edge of the horizon, where heaven and earth meet, there are no longer ordinary mountains and clouds, but a vast expanse of eerie purple.

That was the territory of the Purple-Blue Zerg. The entire land was covered with purplish-black Zerg buildings and vegetation. The floating cocoons and flying units seemed to be layered on top of each other, blocking out most of the daylight. Even the air seemed to faintly carry the unique, cold, and bloody scent of the Zerg.

Even across a thousand miles of defense lines, Chen Feng could still sense the endless danger lurking deep within.

Like a lurking ancient beast, ready to pounce and devour human territory at any moment.

The cold wind howled sharply as it swept across the city wall's edges; the freezing temperatures, enough to crack ordinary steel, continued to rage relentlessly.

However, Chen Feng stood in the center of the cold wind, his clothes fluttering slightly, his blood and qi flowing smoothly throughout his body, and not a trace of coldness penetrating his body.

Since the Marquis of Shaking Mountains' seal was fully awakened, and the souls of a million soldiers were condensed into his bones and blood, Chen Feng's physical foundation has been completely transformed.

Although his cultivation was only at the early stage of the Desolate Rank, with the blessing of the [Marquis's Seal], Chen Feng's physical strength had already approached the peak of the Desolate Rank.

A powerful fighting spirit spontaneously enveloped him, forming an invisible barrier that kept out all the cold and chill.

The mere wind, snow, and extreme cold were not even enough to freeze his skin and flesh.

Just then, two footsteps sounded from behind Chen Feng.

Two guards, dressed in full-body cold-weather armor and carrying automatic rifles, were conducting a routine patrol along the city wall. When their eyes fell on Chen Feng standing on the wall, they suddenly stopped, their faces showing deep confusion and surprise.

The two exchanged a glance and quickly stepped forward.

The young guard on the left spoke with a mixture of urgency and goodwill, whispering a reminder: "Sir, why aren't you wearing any protective gear? The cold winds on the western front are far worse than inside the city. Even a martial artist of the Earth Rank couldn't withstand prolonged exposure to the wind; it would easily freeze their blood and qi!"

The veteran on the right echoed, saying solemnly, "Yes, the border winds have a unique composition, mixed with the chilling and malevolent energy of the insectoid nests and the Illusionary Realm. They easily invade the meridians. Even ordinary martial artists might not be able to withstand them even with their full protective energy. You..."

Both were veterans of the western front defense zone, and they had seen many examples of martial artists ruining their martial arts careers by neglecting to protect themselves from the cold and being infected by cold poison.

Seeing Chen Feng standing in the cold wind without any protection, he couldn't help but feel worried.

Hearing this, Chen Feng finally withdrew his gaze from the Zerg territory, turned to look at the two dutiful guards, a gentle smile appearing on his lips, and nodded slightly: "Thank you for reminding me. I am Chen Feng, the commander of the 79th Field Regiment. I know what I'm doing."

Chen Feng did not offer much explanation.

Because he himself knows that he no longer needs these external things to protect him.

With the Seal of the Marquis of [Shaking Mountains] on his body, his physical body is as solid as a rock of ten thousand mountains, and his fighting spirit is as strong as a thousand-strong army.

The two guards were taken aback when they heard Chen Feng's name, but they didn't dare to say anything or disturb him. They saluted Chen Feng and continued their patrol.

Even as he walked further away, he couldn't help but look back frequently, his eyes filled with confusion.

As the two men turned and continued their patrol along the crenellations of the city wall, walking several dozen steps until they were sure the howling wind had drowned out their voices, the young guard could no longer suppress his doubts and lowered his voice to speak.

"Squad leader, don't you think it's weird? It's freezing cold, even we're bundled up in two layers of winter gear and it's bone-chilling, but he's just wearing a single layer of clothing, standing in the wind and not even shivering?"

The veteran glanced at him sideways, not stopping his steps, and kept his voice low: "Say less... Someone who can stand alone at the highest point of the city wall like this is not someone we can just talk about. Didn't you hear him introduce himself? The commander of the 79th Field Regiment."

"Could it be that demon tamer?" The young guard's pupils contracted slightly, as if he had suddenly remembered something, and his steps slowed by half a beat. "Squad leader... do you think this demon tamer might be the one that was all the rage a while ago, the Great Xia Demon Tamer Chen Feng?"

The veteran stopped abruptly, turning to look at the young guard with shock on his face: "What nonsense are you spouting? Who is Chen Feng? Why would he come to this godforsaken place on the city wall to get some fresh air?"

"But the unit name matches!" the young guard exclaimed urgently. "And look at his demeanor, can an ordinary officer have such an imposing presence? When he approached just now, I felt a tightness in my chest, unlike when he was facing our division commander."

The veteran was silent for a few seconds, his brows furrowed, and he waved his hand: "...The 79th Field Regiment suffered a terrible defeat. Its main force was almost wiped out, and a bunch of greenhorns were crammed in. Now the regiment looks like it's at full strength, but its actual combat power is less than half of what it used to be. It's called the 79th Field Regiment, but it's actually more like a recruit training camp."

"I heard about it too. They said they ran into an ambush by the Zerg, and even the commander was caught in it."

The veteran stopped, turned around and glanced at the figure still standing quietly in the cold wind in the distance, and exhaled a heavy breath of white air.

However, the white mist was torn apart by the cold wind as soon as it drifted out, turning into ice shards.

"If this Captain Chen Feng really is that Demon Slayer, then Regiment 79 might still be saved. But if it's just a coincidence of names... with this crippled regiment, can they withstand the next wave of insect swarms?"

"Master, what you said makes a lot of sense," the young guard quickly complimented.

"Patrol more carefully, and when we get back to the barracks, I'll give you an extra chicken leg," the veteran grumbled.

"That's great!!" the new recruit exclaimed happily.

The veteran didn't reply, but gripped his automatic rifle tighter and quickened his pace forward.

On the city wall, the black figure remained unmoved, like a mountain nailed to the border.
