In the last experiment, the Endless Realm invasion Basler faced lasted only one minute and nineteen seconds.

The one before that, which led to the demonic invasion and the creation of the flesh-mountain Mutant, lasted only two minutes and fifty seconds.

Normally, the results of the experiment—whether it was successful or not—should have been clear by now.

Chen Gu also felt something was amiss. Chu Zheng indeed possessed exceptional qualities. Furthermore, with Dr. Meng Ji secretly manipulating variables, she already had significantly more resources than for a standard Profession Conferral, and this had been increased by another thirty percent. If a problem occurred, the resulting Mutant would be exceptionally powerful, perhaps even surpassing the previous one.

Could Shi Chenghua and Fei Ji actually be right? If Chu Zheng mutates, will it lead to an even more severe disaster?

Chen Gu grew more cautious. He exchanged a glance with Gong Shuxu, and the two powerful Profession Holders each took several steps forward, positioning themselves to the left and right of the generator. They were ready to launch a pincer attack if anything went wrong.

The alarm blared piercingly, and the flashing red light was dazzling, but the inside of the generator remained calm. Another six minutes passed, and then the alarm and the lights suddenly vanished.

The Endless Realm invasion had silently retreated.

Dr. Meng Ji then saw the data representing the test subject's various skills begin to skyrocket. They quickly surpassed the limits of an ordinary person in unison and continued to climb, reaching the peak of the First Energy Level before finally stabilizing.

The doctor's jaw dropped. It took him a while before he rubbed his eyes in disbelief and looked at the data again. There was no mistake—it was real!

His two senior research associates leaped to their feet, pumping their arms in the air and cheering, "Success! It's a success!"

Dr. Meng Ji showed a relieved smile but, ever rigorous, shook his head. "We can't determine if it's a success yet. This data only shows that Chu... this volunteer has successfully undergone her Profession Conferral again. We still don't know if she's a Multi-Profession Holder."

"Next, let's proceed according to protocol."

Although everyone was anxious to find out if the Multi-Profession Holder experiment had succeeded, they methodically checked the contamination levels first before finally releasing Chu Zheng.

When the generator opened, Chu Zheng sat inside, looking disoriented. The researchers called her name twice, but she didn't respond. It was only after they unbuckled her safety restraints that she suddenly jerked awake, looked around, and asked, "Did I... undergo my second Profession Conferral?"

The researchers smiled. "Yes, congratulations!"

Chu Zheng stood up on her own and slowly walked out, feeling as if she were treading on clouds. But just as she was about to leave the generator, she suddenly frowned. "I feel like something's not quite right."

Dr. Meng Ji rushed over at once, asking nervously, "What's the problem?"

Gong Shuxu instantly appeared beside Dr. Meng Ji, pulling him behind for protection. If something was indeed wrong with Chu Zheng, she absolutely could not be allowed to harm the doctor—he was an important "asset" of the Bureau of Mystic Security.

Chu Zheng's expression suddenly twisted in pain. Then, with a scream, she clutched her head and knelt at the generator's doorway. "AH—"

"I... It seems like there are two completely different sets of memories in my mind..."

Her features contorted in agony, and she screamed repeatedly before her eyes rolled back, and she fainted completely.

Gong Shuxu was greatly alarmed and ordered, "Special Operations Team, advance! Highest-level security restraints!"

The Special Operations Team quickly moved in and secured Chu Zheng, who looked as if she was about to mutate and lose control, with the highest-level security restraints.

Dr. Meng Ji, held tightly behind Gong Shuxu, finally couldn't help but cry out, "Chu Zheng, Chu Zheng... what's wrong with you..."

The entire underground hall instantly descended into chaos. However, no one noticed that Chen Gu, who should have been a "pillar of stability" like Gong Shuxu, was left dumbfounded, frozen in place after Chu Zheng uttered her last words.

「Two full days later.」

In a room with the highest security level in the deepest part of the base, Dr. Meng Ji personally conducted a series of the most stringent contamination checks on Chu Zheng.

Chu Zheng showed no risk of mutation.

Her contamination level was 10.07%. While not low, this value was completely acceptable for a Profession Holder who had just undergone her second Profession Conferral.

Chu Zheng had also calmed down by then. Although she still suffered from the two distinctly different sets of "memories" in her mind, she had gradually learned to self-regulate and no longer fainted at the slightest provocation.

At that moment, Dr. Meng Ji, Gong Shuxu, and Chen Gu stood before Chu Zheng's bed. Dr. Meng Ji, filled with anticipation, said, "Next, we need to conduct some tests to verify if our experiment was successful this time."

In fact, two days earlier, Chen Gu had privately told the other two that the experiment was very likely a success. He knew all too well what the so-called "two sets of different memories" implied.

This made Dr. Meng Ji extremely excited; holding back until now had been his limit.

Chen Gu also hadn't expected that something he believed to be impossible had actually resulted in a "miracle."

During these two days, Chen Gu had also been pondering: Why was it successful?

Perhaps my ability to use multiple Profession skills isn't solely because of "Four Hundred People's Past"; or perhaps Dr. Meng Ji stumbled upon the method for holding multiple Professions by sheer luck.

In any case, everything would be revealed today.

But when Dr. Meng Ji spoke, Chu Zheng's expression grew even colder. Just hearing the word "experiment" from the doctor's mouth made her feel like a "human lab rat."

"Come with us," Gong Shuxu said.

The three of them took Chu Zheng to the largest and best-equipped Profession Holder training ground in the base.

Dr. Meng Ji gripped Chen Gu's hand tightly, his voice filled with trust and expectation. "Chen Gu, it's up to you now."

Chen Gu nodded and led Chu Zheng to the center of the training ground to impart his "experience."

"If I'm not mistaken," he said, "your so-called two completely different sets of memories are the abilities of two different Professions. Because that's how it is for me."

"You need to work hard to control them, to completely separate the two."

"When using the abilities of one Profession, don't think about any knowledge related to the other Profession at all. Otherwise, interference is very likely to occur, leading to skill activation failure."

Chen Gu explained a few more details and then had Chu Zheng begin attempting to activate her skills under his guidance.

The Profession Chu Zheng had naturally awakened before was the old Profession [Mist Singer], the same one as the "little demoness" Selena.

The second Profession she awakened, through conferral, was the new Profession [Medium Instructor].

She first tried to use her [Mist Singer] abilities. However, as soon as she opened her mouth, no sound came out; the memories of the two Professions were intertwining and interfering with each other.

"Don't rush," Chen Gu said. "Take it slow."

Gong Shuxu stood to one side, calm and composed, while Dr. Meng Ji was like an anxious old monkey, scratching his head in frustration.

This training, which appeared tedious but was actually crucial and incredibly difficult for Chu Zheng, continued unknowingly for two hours. Chu Zheng was utterly exhausted, and Chen Gu had no choice but to announce, "Let's stop here for now. Get something to eat and rest. We'll continue this afternoon."
