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

boom!!!

boom!!!

Each of Chen Feng's powerful punches caused the patterns and decorations on his armor to flow with golden light, outlining the mysterious and majestic silhouette of his armor.

As the heavy punch was thrown, the muscle lines of the armor's arms appeared exceptionally strong and powerful under the golden light, as if golden flames were burning above the armor, or as if power was surging, giving people an unstoppable feeling of strength.

Each time the golden light collided with the black mist emanating from the demon, it was like the night being dispelled by the rising sun, or the sea rapidly receding.

This time, the incomparably powerful Greedy Demon was firmly suppressed!

In an instant, the face of the greedy demon was smashed to pieces.

His slender body trembled violently.

With his vision already shattered, the greedy demon could only watch helplessly as the next heavy punch came crashing down!

Every punch Chen Feng threw after that was like a heavy hammer striking a block of wood, relentlessly attacking the face of the greedy demon Ding!

Each of Chen Feng's full-force attacks generated a wave of holy flames that spread outwards, scorching all the Seven Kill Demons who wanted to help the Greedy Demon!

After one minute of enhancement time...

The immense power within Chen Feng began to dissipate like the receding tide.

The all-out attack nearly exhausted all of Chen Feng's spiritual energy and depleted most of his physical strength.

Chen Feng also knelt down on one knee, panting and supporting himself on the ground with his hands.

But a muffled thud sounded right in front of Chen Feng!

The 3-meter-tall corpse of the greedy demon also collapsed helplessly to the ground. Not only was most of its upper body scorched by holy flames, but its head was also almost smashed into a piece of rotten flesh.

At this moment, the Greedy Demon had been defeated, and the eight demons that obeyed the Greedy Demon were turned to ashes in the fire.

Chen Feng raised his head and glanced at the corrupt demon Ding, who had completely lost his life. He felt a lingering fear in his heart.

The true strength of the Greedy Demon is actually above Chen Feng's! If Chen Feng hadn't been able to borrow luck points and decisively put them into the Golden Demon-Slaying Armor, greatly enhancing his combat attributes...

Then Chen Feng has probably already become nourishment for the corrupt devil.

Ding!Ding!Ding!

Ding!Ding!Ding!

(๑•̀ㅂ•́)و✧ A firework suddenly exploded in the center of Chen Feng's vision...

[Lucky Contract: Congratulations, host, for defeating a demon two levels higher. +1000 Luck Points]

[Lucky Contract: Congratulations, host, you have achieved the accomplishment of eliminating 10 Xuan-rank Demon Lords. Reward: Luck Points +3500]

[Lucky Contract: Congratulations, host, you have achieved the accomplishment of eliminating one Earth-rank Demon King. Reward: Luck Points +20000]

[Lucky Contract: The system has automatically repaid your Lucky Points loan. Current Lucky Points: 19500]

Chen Feng smiled calmly.

Before taking action, Chen Feng had already reviewed the Lucky Contract System's event tasks.

He can gain a lot of luck points as long as he kills the greedy demon or completes the mission objective.

Furthermore, Chen Feng had seen the Lucky Contract System's relief agreement and learned about the existence of Lucky Value Loans, which is why he so quickly agreed to the system's Lucky Value Loan request...

However, system activities are ultimately...

With the rapid recovery provided by "Fate-Breaking Blade", Chen Feng's exhausted body was gradually repaired.

His spiritual energy and physical strength were recovering at an exponential rate.

He began to look at the colossal underground fortress before him, his gaze fixed on the control room above.

With these 19500 luck points, Chen Feng can enhance one of his skills by nearly 200 times!

Let alone just being a holder of a "main card Green Harbor," even if a powerful Desolate-rank card master like Atreides were here, Chen Feng would have a fighting chance against him!

As Chen Feng walked step by step toward the underground fortress.

Chen Feng's understanding was constantly being refreshed by this magnificent architectural fortress.

In the vast, deep, and secluded space of the colossal underground city, which resembles the belly of a giant beast, a massive iron rock fortress stands behind the Firepower Corridor.

The fortress walls were constructed of massive stone blocks, each infused with metal, exuding a primal and rugged power. These blocks formed the second solid line of defense behind the firing corridor.

The fortress stands in the heart of the underground city, with hundreds of automatic firearms on top, their range covering almost the entire vast underground space.

If the Super Beast Dungeon is a refuge that provides people with shelter from the apocalypse, then this central fortress is the most impregnable and difficult-to-break safe house in the entire refuge.

Chen Feng walked to the entrance gate below the fortress.

Then, based on the 26-digit gate password given by Ye Qingnan, they began to enter the gate password.

However, at that moment, something unexpected happened to Chen Feng!

The gate's display screen showed constantly changing numbers and symbols, but a conclusion was quickly reached.

[WARNING: Incorrect password!! If the password is entered incorrectly twice, the automatic fire control system will lock the current visitor and eliminate them!!]

Chen Feng glanced warily at the automatic firing mechanism atop the fortress, then took out the code slip again, reviewed it once more, and began entering the code once more...

[WARNING: Incorrect password!! If the password is entered incorrectly once, the automatic fire control device will lock the current visitor and eliminate them!!]

Now, Chen Feng finally understood.

The owner of the "Green Harbor Main Gate" must have changed the gate password in some way, which is why the password I entered was incorrect!

Even with a high luck stat, Chen Feng now felt a bit overwhelmed.

Even if I could forcefully break through the alloy gate in front of me, once the fortress's defenses are activated, countless traps will still be set in motion inside the fortress, and I would have no chance of reaching the control room.

However, Chen Feng still had some good news.

That is, the fortress's fire lock-on mechanism was set by the engineers at the time, except for a complete system reinstallation and rule rewriting.

Otherwise, the fortress's fire lock-on mechanism cannot be actively triggered by the holder of the "main card Green Harbor".

Chen Feng let out a deep breath.

After thinking for a while, Chen Feng looked up at the top of the fortress's defensive wall.

Above the towering defensive wall, there is a hidden entrance to the fortress.

Chen Feng had to carefully navigate through the numerous fire traps and use his enhanced power to break through the hidden entrance to the fortress. Only in this way could he greatly reduce the probability of being targeted by the fortress's firepower.

And this is Chen Feng's only remaining plan...
