Chu Zheng's eyes flashed with an imperceptible brightness, her smile rippling even more. Today's training success rate had increased significantly.

Chen Gu saw this and nodded inwardly. After adopting a dual profession, the girl really had become much more cheerful, which was a good thing.

At the same time, in the hall where the device was located, Shi Chenghua stood to one side, enviously watching Fei Ji as she entered the device.

Both had undergone physical tests in the morning, meeting the standards. However, Fei Ji's results were slightly better.

Dr. Meng Ji stood with his arms folded behind the multitude of monitoring equipment, overseeing the orderly progress of the preparations.

Fei Ji, full of confidence within the device, buckled the chair's straps in cooperation with the researchers and then gestured triumphantly to Shi Chenghua outside, flashing a smile.

Subsequently, the airtight door descended uniformly and locked into place with a CLICK.

"Begin!" commanded Dr. Meng Ji, as the initiation procedure, already repeated several times, commenced once again.

Bright white light surged over everyone like a tide, including Shi Chenghua whose expression was somewhat complex.

Shi Chenghua and Fei Ji had always had issues with Chu Zheng. But were the two of them really that close? Perhaps not. Chen Gu only noticed the former, while Gong Shuxu, a Sixth Energy Level Psychological Spy, keenly observed the latter. Therefore, his confidence in them facing the Endless Realm was even lower, despite having used Psychological Spy techniques to mitigate their mental issues as much as possible.

On the monitoring equipment, the readings for Fei Ji's first initiation steadily climbed, quickly nearing a critical threshold. Crossing this threshold in certain data meant a mutation!

Then, that familiar alarm and red light appeared together: "Endless Realm invasion detected!"

Gong Shuxu immediately heightened his alertness. Just as Dr. Meng Ji was about to say something, the data on the monitors surged, turning blood red in an instant!

BOOM—

From within the device, a sound emerged, like an explosion or the growl of a colossal beast, followed by a cold, slimy, and frenzied aura that swept out wildly.

The researchers around felt as if a demon's tongue, drenched in foul saliva, had licked from their faces all the way to the backs of their necks!

"Ah!"

Several younger researchers screamed and fell to the ground, frightened by the aura alone, with the Mutant not even appearing yet.

Gong Shuxu's expression changed, and he swiftly stepped forward to block the entrance to the device. Dr. Meng Ji, shocked, exclaimed, "The Endless Realm has just invaded and she's already contaminated? Truly powerless against temptation, how much evil and greed must lurk in her heart..."

Some black, viscous fluid, like blood and carrying a foul stench, seeped out from the device.

Everyone knew that before the device was opened, the entire structure was completely sealed, making it impossible for any liquid to seep out. Clearly, this fluid was expelled by the Mutant using its abilities.

Then, as if finding a breach in a dam, the viscous fluid poured out rapidly, and soon the entire hall turned into a black pool!

「...」

Chen Gu suddenly sensed something. He looked down at his feet, and through the layers of the base's structure, seemed to directly see that black, viscous fluid!

Chu Zheng asked, "Instructor, what's wrong..."

An ear-piercing alarm suddenly resonated throughout the base!

Chu Zheng was taken aback. "It really is a mutation!"

Chen Gu grabbed her. "Quick, follow me."

Leading Chu Zheng away from the conditioning field and on high alert, they rode the elevator to the surface. A Bureau of Mystic Security special service team awaited them there, led by a Sixth Energy Level officer Chen Gu hadn't seen before.

The officer said, "According to the plan, take Chu Zheng away immediately!"

"Okay!" Chen Gu replied.

Chu Zheng suddenly grabbed Chen Gu, who was about to return to the base, her eyes filled with urgency. "Instructor, where are you going?"

"I'm going to check on Old Man Gong Shuxu and the doctor. They've been good to me; I can't just abandon them."

Chu Zheng grew anxious. "This Mutant is very powerful, isn't it? You could sense it in advance!"

Chen Gu feigned disdain. "I've killed more than one powerful Mutant! You go back first. I'll bring them to see you soon."

"No!" Chu Zheng clung to him tightly. "If you don't go, neither will I..."

THUD! The Sixth Energy Level officer knocked Chu Zheng out without any hesitation, then nodded at Chen Gu while carrying her away swiftly.

Chen Gu gave a wry smile. This officer, like Old Man Gong Shuxu, had a strong sense of responsibility and loyalty to the Bureau of Mystic Security, choosing to defend the bureau's interests first and foremost.

Chen Gu turned back and took the elevator downstairs. On the way, he encountered other staff retreating to the quarantine area. They couldn't provide any clear information but knew that Shi Chenghua and Fei Ji were in the device hall.

A notion struck Chen Gu, sparking a few possibilities in his mind.

「...」

Chu Zheng regained consciousness more than ten minutes after being placed in the vehicle. The Sixth Energy Level officer had not been heavy-handed. Her current physical condition, remarkably strong, was no less than Chen Gu's had been initially.

Seeing her indignant expression, the Sixth Energy Level officer knew what she was about to say and cut her off coldly, "Even if Chen Gu didn't volunteer to go back, the director had orders for him to handle this accident."
