"Chen Feng, we've completely cleared out the Soul Suppressor Golems on our side. How's it going on your end?"

Ye Qingnan's voice came through the communication equipment.

Upon hearing this, Chen Feng immediately stopped in his tracks.

In his assessment, even the well-trained Starfish City Guard, facing 20 Earth-rank Soul Suppressor Golems, could only manage to buy enough time at best.

It wasn't until Chen Feng personally shut down the control system of the colossal dungeon that this continued.

However, what Ye Qingnan and Chen Feng are saying now is that they have dealt with all the Soul Suppressor Golems.

"The situation doesn't seem as simple as Ye Qingnan thought."

The fortress corridor is outlined with smooth, curved lines, cleverly utilizing curves and angles to create sniping positions.

In addition, the walls inside the fortress are made of a special composite metal material that is not only incredibly strong but also has the ability to adaptively regulate temperature and provide sound insulation.

No matter how harsh the external environment, the corridor always seemed to maintain a suitable temperature and absolute quiet, providing a safe and comfortable space for the people inside the fortress.

However, this fortress had not been used for hundreds of years, so along the way, Chen Feng encountered more than a dozen traps that were damaged due to years of disrepair.

This made Chen Feng quite emotional, as he simply couldn't imagine how difficult it must have been to infiltrate that fortress back then.

"Chen Feng, the defensive fortress has three main control rooms, each with independent management authority. But since the Greedy Demon is dead, I guess the 'Green Harbor Holder' is in the control room of the Firepower Corridor," Ye Qingnan said.

"I know, I'm right in front of the alloy gate."

"We'll be there in about 10 minutes."

After shutting down the communication system, Chen Feng began entering the password for the display screen next to the main control room door.

The main control room has a very spacious interior with a multi-layered ring structure.

The central area features a massive holographic sand table, surrounded by multi-layered operating platforms. Each layer houses different functional areas, ranging from intelligence analysis and weapons control to communications dispatch and strategic planning.

Each region is both relatively independent and closely connected, forming an organic whole.

However, to Chen Feng's surprise, the main control room seemed to have been destroyed by some powerful force, with all the monitoring screens and instrument panel monitors damaged.

Within a short period of time, the control room that operated the various systems of the colossal dungeon was no longer usable.

Chen Feng reached out and stroked the alloy outline of the operating platform, immediately feeling a scorching heat next to the saw cut that tore through the metal.

Chen Feng's eyes sharpened.

Chen Feng immediately realized that the system was being disrupted by extremely rich life energy.

Using life energy is precisely what "Green Harbor" excels at.

Chen Feng continued walking towards other places...

Just as Chen Feng walked to the management platform that Li Chongji had repaired, his keen senses allowed him to hear a faint mechanical sound.

Chen Feng frowned.

They immediately used the high-energy Zerg blades to insert into the alloy baffle of the management platform and cut a square slit in it.

With a forceful pull of both hands, he tore the alloy baffle off the control panel.

Inside the complex interior of the control panel, numerous precision components are tightly arranged, resembling a mysterious labyrinth forged by technology.

However, next to the machine filled with complex circuits and modules, a faint sound particularly caught Chen Feng's attention.

Beep!Beep!Beep!

Beep!Beep!Beep!

Chen Feng crawled into the control panel and immediately discovered a small machine hidden in a relatively secluded corner deep within the control panel.

Its outer shell is made of a special alloy material, and the machine is not large, about the size of an adult's fist.

The small machine also has a tiny indicator light on top, which flashes on and off rhythmically with a "beep beep beep" sound, as if telling some unknown secret.

After thinking for a moment, Chen Feng carefully removed the small device.

It is an automatic programming device that can control various types of machinery or production processes through technical means of input or output.

However, the machine did not look like it was made hundreds of years ago.

Because if a small machine were to be used to infiltrate the most advanced defense system of the Great Xia Kingdom at that time, the virus to be implanted would need to meet multiple technical requirements, including virus implantation, vulnerability exploitation, and automated control.

This was almost impossible at the time.

Chen Feng used the Lucky Contract System to click on the small machine in front of him and immediately obtained its ownership information.

[Machine Type: Automatic Program Rewriting]

[Mechanical Function: This hacking machine employs a highly modular technical architecture, with each module operating independently yet working closely together, capable of automatically rewriting system program functions.]

[Mechanical Modules: Intelligent Scanning Module, Virus Generation and Injection Module, Program Rewriting Engine, Remote Control and Communication Module]

[Machinery Ownership: Li Chongji]

Li Chongji?!

Chen Feng suddenly remembered that he had also found him on the guard's wanted list.

What puzzled Chen Feng the most was that although his combat strength was the lowest among the wanted people, his wanted level had reached the high-risk standard, which showed that Ye Qingnan obviously knew about this person as well.

Just then.

The automatic rewriting program held in Chen Feng's hand stopped beeping, and a sentence began to appear on the screen.

Chen Feng looked inside and immediately saw two words.

Run!

Before Chen Feng could react, a rapid buzzing sound rang out throughout the control room.

These buzzing sounds, like ferocious beasts lurking in different parts of the control room, kept emitting piercing shrieks, but soon stopped abruptly.

Chen Feng immediately knew what had happened. His eyes hardened, and he activated the Silver Demon-Slaying Armor, which had the strongest defense, and used "Army" to strengthen the armor's toughness three times.

The next moment!!

Several blinding white lights suddenly shone, as if the sun had been compressed and released its energy in an instant.

Immediately afterwards, a deafening roar exploded like thunder, the surveillance screens on the wall shattered, and glass shards flew like raindrops.

The shockwave generated by the bomb spread outwards with overwhelming force.

The instruments on the control panel were violently overturned, and various wires and parts flew wildly in the air. Documents and papers were caught in the violent airflow and scattered everywhere like helpless butterflies.

Even Chen Feng, clad in silver armor, was thrown to the ground by the powerful impact!

The moment Chen Feng looked up, he saw the control rooms, constructed of tough materials, rapidly disintegrate in a flash of white light!
