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

"Alright, I'll have a few Blue Leopards follow you down there." Wu Yingguang nodded.

At TN71 base, the equipment of the Red Fox Squad would be considered T0 level even by the standards of the Great Xia army, and they also bear various other labels.

—Such as multi-functional modular combat components, tactically versatile, high-end combat power, and tactical overwhelming.

The Blue Leopard Regiment is simply a special forces regiment within the TN71 base area.

Their armor and weapons have super impact resistance, but their combat functions are limited, and the number of combat components in their armor is only one-fifth that of the Red Fox's.

This also means that base personnel entering the Blue Leopard Legion do not need to become high-ranking combatants.

All that is needed are combat-oriented individuals with outstanding physical abilities.

Just as Chen Feng was about to lead several Blue Leopards towards the water, Xu Ri Dong Cuo called out to him.

"What's wrong?"

"I'll go down with you later." Xu Ri Dong Cuo smiled as he took off his combat backpack and even his defensive armor.

"Then why did you take off your protective armor?"

"Let me show you the true combat power of this demon slayer. Oh, and I forgot to tell you, the water is my home turf."

Before he could finish speaking, Xu Ri Dong Cuo had already stepped into the icy water ahead of Chen Feng.

His footsteps were extremely light; the moment his toes touched the water, not even a tiny splash was made, a stark contrast to the blue leopards beside him, who wore heavy armor and made a clanging sound when they waded through the water.

Just then, a large cloud of water vapor suddenly surged up from the waters surrounding Xuri Dongcuo.

As if drawn by an invisible hand, fine water droplets rapidly condensed and shaped upwards from his ankles, eventually forming a Nightmare Demon-Slaying Armor that perfectly conformed to the contours of his body!

The Nightmare Demon-Slaying Armor, seemingly sculpted from water, featured streamlined, thin-edged ridges on its shoulder armor, elbows, and knees, eliminating any gaps that might hinder movement.

From the outside, it seems to have no restrictions on movement at all, like a second layer of skin formed on the skin.

On the tactical detector in Wu Yingguang's hand, the cursor representing Xuri Dongcuo even flashed several times, and several times it directly left the detection range.

Even the most precise underwater motion capture module in Red Fox's possession could not completely lock onto the movement trajectory of Rising Sun Winter.

"Is this the home-field battle armor you were talking about?" Chen Feng said quietly.

"The Nightmare Demon-Slaying Armor combines the abilities of the Nightmare Clan's Dark Gods and Demon Slayers. As long as I'm not in someone else's territory, there's no limit to my movement speed."

"Sunrise Winter Mistake said softly."

"How about it? This outfit isn't any worse than your Starry Sky Demon-Slaying Armor, is it? Let's get in the water."

Looking at the arrogant Xu Ri Dong Cuo before him, Chen Feng, unusually intrigued, immediately summoned his Starry Sky Demon-Slaying Armor, grabbed the decoding terminal given to him by Su Wan, and led several Blue Leopards underwater...

However, as soon as Chen Feng stepped into the underwater sealed passage, he felt a bone-chilling cold emanating from the Starry Sky Demon-Slaying Armor.

This body of water is an underwater blockade line built by TN71 base specifically for wartime in-depth defense; it is a standard military-grade death tunnel.

The narrow passage, no more than fifteen meters wide and a few meters high, is flanked by reinforced concrete walls inlaid with explosion-proof materials. The pitted walls are covered with bullet holes and charred marks left by explosions.

In this body of water, the only source of light is an emergency red light that hangs every ten meters overhead. The scarlet light can only spread out within a range of three or four meters in the murky water.

What alarmed Chen Feng the most was that the water was also riddled with various kinds of mines.

"The tunnel is 320 meters long and contains magnetic fuse mines and induction anchor mines. Automated firing points will be deployed in the middle section, and heavy anti-armor blocking devices will be at the end. Be careful, everyone." Wu Yingguang's voice came through the communication headset.

Magnetic fuse mines are a type of mine designed to target metal components such as alloy armor, weapons, and tactical modules worn by combat personnel.

When these combat metals pass over the mine body, they will disturb the surrounding magnetic field. When the change in the magnetic field reaches the preset threshold of the fuse, it will directly trigger an explosion.

The induction anchor mine is suspended at a preset water depth, and will not sink to the bottom or drift with the water flow.

The core triggering mechanism is also a composite induction fuse, integrating acoustic, magnetic, water pressure, and infrared multi-mode detection. It can not only sense metal, but also actively capture signals such as water flow disturbances and underwater sonar signals based on the updated target characteristics of the base personnel.

These weapons and equipment constitute a military-grade containment system designed for narrow underwater passages.

From passive concealment and delay, to active precision annihilation, and finally to absolute firepower annihilation, it can be said that once locked on, almost no strong person below the Earth Rank can survive.

"Blue Leopard Squad, form a triangular shield formation and follow me, maintaining a distance of three meters. Avoid touching the rock walls and mines on either side, and be especially vigilant for potential attacks from the alien beasts," Chen Feng commanded in a deep voice.

"receive!"

The six Blue Leopard team members, in pairs, held their blast-proof energy shields horizontally in front of them, carefully avoiding the various mines floating in the water all around.

However, Xu Ri Dong Cuo swam around the group at an extremely fast speed, narrowly missing the detonation threshold of the mines each time.

"Don't be too nervous. The defense design of this passage is aimed at those wearing heavy iron shells. For me, it's no different than walking through my own backyard." Xu Ri Dong Cuo chuckled.

However, as soon as he finished speaking, Xu Ri Dong Cuo suddenly stopped and raised his hand to press down hard on the shoulder of a Blue Leopard team member beside him.

"stop!"

These words instantly put everyone on edge.

The Blue Leopard team member who was being held down by Xuri Dongcuo immediately looked down and saw a cylindrical, jet-black mine flashing a blinding red light at his ankle.

Clearly, the magnetic fuse mine had been activated by his alloy armor; the countdown was ticking rapidly, and there were less than two seconds left until the explosion!

Several Blue Leopard team members froze on the spot, holding their breath.

However, at this critical moment, Asahi Dongtso took action once again.

No one saw how he made his move; they only saw a pale blue afterimage flash across the water.

As soon as Xu Ri Dong Cuo's fingertips extended, countless water needles as thin as hairs pierced precisely into the core interface of the mine fuse.

At the same time, the surging water in his palm suddenly tightened, like an invisible giant hand, tightly wrapping the entire mine and locking the impending shockwave within the water barrier.

"Sizzle—"

With a faint sound of short-circuiting electricity spreading along the water flow, the red light on the mine went out immediately, and the fuse was completely disabled by the water needle.

Only then did the group of blue leopards realize the cold sweat seeping down their backs.

Even through the armor, one could feel the lingering fear of surviving a catastrophe.

"Some of the mines in this passage have magnetic fuses that target metal armor. You guys in your metal shells need to be careful and follow Chen Feng closely." Xu Ri Dong Cuo smiled and patted the stunned Blue Leopard in front of him.
