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

"What's going on?" Chen Feng, who came out of the stairwell, hurriedly entered the assault vehicle of the second squad.

Inside the Combat Academy's underground parking garage, all three squads' assault vehicles were on fire, ready to speed off to their destination at any moment.

Qu Lu, who was sitting inside the assault vehicle, immediately handed the mission documents in his hand to Chen Feng.

"We received an anonymous tip that the owner of the artifact 'Main Card Green Harbor' is located in an underground building."

Qu Lu paused, but a serious look flashed in his eyes.

"To our surprise, the anonymous report included traces of energy bursts from the magical artifact 'Main Plate Green Harbor.' After verification by Captain Ye and the analysis department, the authenticity of the evidence was confirmed."

Upon hearing this, Chen Feng took out the photo from the document.

In that photograph, it's as if all the colors have been reconstructed by a strange force.

The background is a deep black tunnel, above which is a large clump of emerald green smoke, the dust particles in the smoke refracting an emerald halo at certain angles.

Beneath the emerald green smoke was a figure entirely in black.

What he was holding between his index and middle fingers was a long card engraved with vine patterns—the spirit artifact "Main Card Green Harbor".

Looking at this bizarre scene, Chen Feng couldn't help but feel a little puzzled.

"Team Leader Qu, you mentioned before that the main Green Harbor possesses powerful vitality, and its strongest ability is to infuse it with vitality, turning inorganic matter into semi-organic life forms," ​​Chen Feng said.

"That's right, the 'Main Talisman Green Harbor' can rewrite the original code of life. It was originally a fragment of the ancient World Tree's core, containing the essence of the World Tree's energy accumulated over billions of years."

Chen Feng looked at the photo again and continued to state his question.

"But in this picture, I don't seem to see any other living beings next to the 'Green Harbor' user. Does this mean that the person who took the picture already knew his identity and deliberately took the picture to show us?"

Upon hearing this, Xiao Song's eyes widened.

"That makes sense...? As the holder of the 'Main Green Harbor,' he can sense the life force of living beings. Logically, if he doesn't want his location to be revealed, he shouldn't be photographed face-to-face."

Qu Lu nodded, seemingly approving of their analysis.

"We've already discussed this with Ye Qingnan. Based on our analysis, the person who took the photo might be a rival that even the owner of the 'main property, Green Harbor' could potentially lose to..."

"Could it be a demon?" Liu Siyu asked.

"Very likely."

Chen Feng was stunned. He remembered what happened to Wei Yang when he arrived at the scene later.

Chen Feng felt he would never forget that scene.

......

When the three guards' armored vehicles quickly arrived at an abandoned subway entrance.

Qu Lu and Dali immediately got off the assault vehicle and led their respective teams to the abandoned subway entrance.

Dali: "I'll have Captain Wu guard the exit, and the two of us will lead men down to search. Captain Qu, are there any problems?"

Qu Lu: "Of course not."

Dali: "This operation is dangerous, but it may be very close to the truth. I hope that our two teams can work together."

Qu Lu: "This is what I've been telling my teammates just now."

Qu Lu turned around and looked at Liu Siyu and Chen Feng as soon as he finished speaking.

At this moment, Liu Siyu was holding a demon-hunting spear on her signature Sirius mechanical gauntlets, while Chen Feng held a defensive shield...

As the defensive force guarding Starfish City, the Starfish City Guard not only needs to be constantly vigilant against the expansion of the giant beast's territory, but also needs to guard against the invasion of the city by demons.

Therefore, in their decades of defense work, the Starfish City Guard has designed a variety of weapons specifically designed to target demons.

[Demon Hunter Pistol - The streamlined body is covered with obsidian patterns, and the barrel is wrapped with silver runes. It can fire demon-suppressing bullets/tracking micro-bullets, and the barrel cooling system uses liquid nitrogen circulation to ensure continuous firepower.]

[Demon Hunter Spear - The spear body is forged from the dragon bones of a sacred beast, its surface covered with dark red patterns. The spearhead is a three-pronged spike capable of piercing 30-centimeter-thick demonic scales. The dragon blood toxin injected into the spearhead will destroy the demon's cellular structure. Holding down the trigger activates "Holy Shield Mode," briefly knocking the demon back.]

[Defense Long Shield - The shield surface has an irregular hexagonal shape, which can withstand direct fire from anti-materiel sniper rifles. The "energy deflection layer" on the shield surface can convert magical attacks into heat energy and dissipate them. The anti-magic coating on the surface can generate a small defensive force field against demonic attacks.]

[High-powered semi-automatic sniper rifle - the bullet is made of depleted uranium alloy, which can detonate twice inside the armor after penetrating the demon armor. The magazine can be loaded with 10 bullets instantly without manual operation.]

[Automatic Rifle - Theoretical rate of fire 800 rounds/minute, bullet with built-in micro explosives, blast radius 2 meters, suitable for repelling attacking demons]

"We're going in now," Liu Siyu said half-jokingly to his teammates behind him, while weighing the Demon Hunter spear in his hand, his face immediately showing a heroic and dashing expression.

"Check the communication system, check the defensive force field device," Chen Feng added, and began adjusting the equipment he was wearing.

"Automatically calibrate the time and do a final check..." Xiao Wei said at the end.

Once all the guards had completed their preparations for the operation, they donned their helmets and masks and carried various types of weapons.

We began to walk step by step into the subway entrance, which was completely swallowed by darkness.

...

Although the guards' weapons were equipped with lighting devices, compared to the subway station, which resembled the belly of a steel behemoth, the twelve constantly searching searchlight beams looked extremely small.

The larger number of military and police personnel could have provided more assistance; however, in battles involving spirit artifacts, their casualties would be greatly increased, and in the chaos, their firearms might accidentally injure members of the guard.

Therefore, no Starfish City military or police personnel were involved in this operation.

"It stinks here..." Xiao Wei couldn't help but complain in a low voice.

Xiao Song relaxed his guard and walked back to Xiao Wei's side, comforting her, "Remember to let me protect you later. I have a high-powered sniper rifle, specially designed to deal with rage and gluttony."

"You two, be quiet," Liu Siyu ordered.

The environment inside the abandoned subway station is terrible.

The subway tracks were corroded and rusted, and the walls of the train passages were covered with mold. The air was filled with the damp smell of rust and even the stench of old urine stains.

Just as the echoes of the guards' footsteps collided repeatedly in the narrow train tracks and carried into the depths of the subway tunnel, Qu Lu and Dali both raised their right hands simultaneously.

He made a gesture indicating that he should be on guard.

Only then did all the guards notice the anomaly...

Those were faint, indistinct roars of demons.
