Jiang Cheng remained calm. "Of course, I want to help you, but you must cooperate. I need to know exactly what happened here."

Liu Hui suppressed her excitement and sighed. "What else could happen? As you can see, this place is the Watchers' testing ground."

"After the first generation of Shen Hong... after you defected, the Watchers secretly launched a new generation of Shen Hong cultivation plan. That's when I was chosen as one of the backup leaders for this project."

"I was very young back then. I swear, before I came here, I never imagined it would be like this. But my superiors told me that it was all for the sake of humanity's survival, that we had to eliminate the defected Shen Hong, otherwise they would bring disaster to this world."

"I believed it, and so did many other young people like me. We all believed that the Watchers were the cornerstone of guarding the order of the night. That was our belief when we joined the Watchers."

"We devoted ourselves wholeheartedly to various complex experiments and treatments, hoping to cultivate more powerful warriors. But unfortunately, our experimental subjects... they were far from having the talent you guys had. During the forced acceptance of the Door, most of the experimental subjects died, and the surviving ones suffered varying degrees of erosion. In the end, less than one in ten survived."

"What kind of people were those experimental subjects?" Jiang Cheng asked.

Liu Hui slowly shook her head, the sadness in her eyes touching. "They weren't criminals, not people who were sent here to atone for their sins. They were Watchers like me. Most of them were very young, and a large number of them voluntarily joined this plan with a passion to completely eradicate the Shen Hong scourge. But who would have thought... who would have thought that the code name given to them by the higher-ups was also Shen Hong!"

With a bleak smile, Liu Hui's emotions fluctuated violently. "For a long time, the experiment made no progress. The higher-ups were furious. A few days later, we suddenly discovered that children were being sent as experimental subjects. Several researchers immediately objected, but by then, many people had gone crazy for this experiment, and the voices of opposition were quickly drowned out. What made everyone even more ecstatic was that these children's talents, obedience, and especially their acceptance of the Door, were much stronger than those of the previous experimental subjects."

"As the experiment progressed rapidly, more and more children were sent here. And the few researchers who had protested before disappeared silently. No one knew where they went, and their work was naturally replaced by others."

"Of course, for us, who were already in a state of fanaticism at that time, the smooth progress of the experiment meant everything. Nothing else mattered."

"As we deepened our contact with those children, we gradually learned some inside information. It turned out that these children were not seriously ill or neglected orphans. Most of them had families, they had relatives. They were kidnapped."

"The Watchers conducted a wide range of screenings, intentionally selecting children with extraordinary talents. This practice was utterly wicked, but it must be admitted that it did play a huge role in promoting the experiment we were conducting at the time. So batch after batch of Shen Hong members were created."

"They grew up here, seeing only us researchers in white isolation suits, and seeing only this scenery dozens of meters underground, these cold reinforced concrete structures."

"They rarely saw the sunlight, and the clothes they wore were all hospital gowns. In their subconscious, they were all patients who needed treatment, and we were their doctors, the people who could prolong their lives."

"You're all so damn evil!" Fatty gritted his teeth in hatred. He couldn't understand how these people could have no bottom line for the sake of so-called benefits.

Jiang Cheng glanced at Fatty, and Fatty slowly quieted down, but still stared at Liu Hui with unkind eyes. "Continue," Jiang Cheng said, looking at Liu Hui.

Now Liu Hui had also calmed down. So many years of repentance had been suppressed in her heart, and at this moment, she also needed a listener. "As the Shen Hong we created became more and more powerful, we also realized the problem. The speed and extent to which these experimental subjects were eroded by the Door gradually escaped our control. They became more and more uncontrollable, and the communication between them and us became weaker and weaker."

"We tried to assign a dedicated listener to each qualified product, that is, experimental subjects with a level one danger rating or higher. Our internal call sign for this was 'keeper'."

"This configuration did play a certain role at the beginning, greatly alleviating the violent nature of the experimental subjects, but this was by no means a long-term solution. What we needed was not only powerful ability users, but more importantly, we needed them to be controllable, to be able to obey our orders and be used by us."

Hearing this, Jiang Cheng couldn't help but frown. He suddenly thought of the whistle he had heard not long ago. The situation was extremely critical at the time. Dozens of experimental subjects had surrounded them, but after that whistle, they quietly retreated. Those experimental subjects showed great obedience to the whistle. This was unimaginable for disciples eroded to that extent.

It was the masked man... the whistle was hanging under his neck!

That unique level three danger monster!

Noticing Jiang Cheng's expression, Liu Hui was not surprised at all. "That's right, you've noticed him too. His code name is Vortex (Wo)."

"Vortex (Wo) is the most unique of all the experimental subjects, and the only experimental subject in history to reach a level three danger rating, but what's dangerous is not himself, but his ability. He can communicate with many dangerous experimental subjects in a way we can't understand at all."

"Even now, we don't know how he does it. After all, some experimental subjects have severely mutated limbs, or even parts of the torso and brain. The most extreme case is that a level two danger experimental subject has lost most of his brain, but he can still receive Vortex's (Wo) signals and show considerable affinity and obedience."

"With him, these uncontrollable experimental subjects are no longer independent individuals, but a whole." Liu Hui took a deep breath and slowly exhaled. "It's no exaggeration to say that if the Shen Hong outside are compared to an army, then Vortex (Wo) is the brain of this army."

Jiang Cheng fully understood how terrifying an army composed entirely of level one, or even level two, dangerous experimental subjects would be. What was even more terrifying was that this army could be commanded.

It was all because of this masked man codenamed Vortex (Wo)...
