With three superpowers at his fingertips, he could dominate the 1970s.

Suppressing his excitement, Qian Weiguo was the first to step out.

He removed his protective mask and took a deep breath. The harsh white light from the corridor lamps shone on his face, clearly revealing his expression—calm and composed, though his heart was in turmoil.

Only he himself knew what he had just seen behind that door.

The image of that girl sitting cross-legged in the center of the nuclear contamination room, surrounded by a faint purple light, was impossible to suppress.

The girl's secrets were far greater than he had imagined.

But he won't ask anything. There are some things he shouldn't know, so he'll pretend not to know.

Qian Weiguo glanced at the researchers waiting anxiously in the corridor and raised his hand to press down.

"Don't panic, everyone, they're alright."

He paused, his tone as calm as possible, as if he were stating something perfectly ordinary, "This is a comrade sent by the Second Administration Bureau, specializing in nuclear radiation research. We just had her go in and conduct a test, and it actually worked."

Behind her, Jiang Zhiyu followed her out. The zipper of her protective suit was zipped up to the top, and her face mask was pushed up to reveal a clean and peaceful face, showing no signs of anything unusual.

Gao Xiaolan was the first to rush forward, looking her up and down, her voice trembling.

"Are you really okay? No dizziness? No other discomfort? Feeling nauseous? Any pain anywhere?"

Jiang Zhiyu felt a warmth in her heart from the barrage of questions. "I'm fine, everything's alright. I'm so sorry to have worried you all."

Gao Xiaolan finally let out a sigh of relief, but her eyes were red. She blinked hard twice to suppress the soreness, then turned around to attend to other things.

Qian Weiguo gestured with his chin towards the researcher next to him, "Go in and measure the radiation levels, measure everything thoroughly."

Two researchers, dressed in protective suits and carrying testing equipment, quickly entered the nuclear contamination room.

Jiang Zhiyu stood outside the door, chatting with Seventeen.

"Host, your absorption just now reduced the radiation concentration in the core area by at least 90%."

"Ninety percent? Is the remaining ten percent enough for them to continue their experiments?"

"That's enough. The residual radiation level is well within safe limits. There's no problem going in to conduct experiments wearing proper protective gear; in fact, the protection level can be lowered."

"That's good, then it wasn't a complete waste of time."

"Host, you've done more than just a lot of work; your poison-based abilities are almost at level three by now."

"Don't be too happy yet, you're still far from it, just one step away."

A few minutes later, a gasp suddenly came from the nuclear contamination room, followed by hurried footsteps.

A researcher stumbled out, clutching a testing device, his face contorted in horror.

"Mr. Qian, the radiation level in the core area has dropped by 90%!"

The corridor fell silent for a second, then erupted into chaos.

"What did you say? Ninety percent?"

"Impossible, the instrument must be broken!"

"Get another one for testing! Go get it now!"

Qian Weiguo remained expressionless, as if he had expected this. With his hands behind his back, he spoke calmly and unhurriedly, "Don't rush, test again. Test both the middle and outer layers."

The second researcher ran in carrying another testing device.

Gao Xiaolan stood in the corridor, her hands tightly gripping the hem of her white coat, her knuckles turning white.

She spent five years in the lab, dealing with nuclear radiation every day. She understood the meaning of radiation levels better than anyone, and she knew better than anyone what it meant to reduce the radiation concentration in the core area by ninety percent.

That's not an amount that can naturally decrease in a day or two.

That was decades ago.

No, it might take decades. They've tried countless purification methods, none of which have been effective. The decay cycle of nuclear radiation is measured in years; it's something that cannot be interfered with by human intervention.

But this young woman went in and did it in just a few hours.

Gao Xiaolan felt that her worldview was being repeatedly crushed.

A few minutes later, the second researcher came out, his face even paler than the first.

"Radiation levels in the middle layer decreased by 85 percent, and in the outer layer by 78 percent."

He swallowed hard and added, "All three instruments have been calibrated, and the data is correct."

The corridor was so quiet you could hear everyone breathing.

An older researcher pushed his way to the front, grabbed the testing device, and said, "I'll do the test myself!"

He rushed into the nuclear contamination room carrying his equipment, his steps quick and large, the hem of his white coat flying up in the air.

Everyone held their breath and waited.

The air in the corridor seemed to freeze; no one spoke, only the faint hum of the fluorescent lights could be heard.

Jiang Zhiyu stood quietly in place, her gaze peaceful.

Qian Weiguo stood beside her, his hands still behind his back, his emotions unreadable.

Two minutes later, the old researcher came out.

He walked slowly, as if he was processing what he had just seen with each step.

On the screen of the testing device in his hand, the value remained steadily within the green safe zone. He checked it three times and pressed the retest button several times, and each time the result was exactly the same.

He slowly raised his head, his gaze falling on Jiang Zhiyu. His lips moved, but he couldn't utter a word for a long time.

Finally, he turned to Qian Weiguo, his voice hoarse.

"Mr. Qian, the retesting of the entire area is complete. The residual radiation level in the core area is below the safety threshold, and the middle and outer layers have fully met the standards."

"In other words... that nuclear-contaminated chamber is now ready for normal use."

The corridor instantly erupted in excitement.

"Is it working normally?"

"You mean we can go into that room now? And we don't need to wear protective suits?"

"Yes! In the past, we had to go in for experiments even knowing there was radiation. Now, wouldn't it be better to periodically clean out the radiation to reduce our risk of being exposed to it?"

"Who exactly is this comrade? The Second Administration Bureau? I've never heard of him before?"

Qian Weiguo raised his hand to gesture for silence, "The specific methods are classified and cannot be discussed in detail. In short, you've all seen the results. From now on, that lab can proceed with its experimental schedule as normal, and the protection level should follow standard procedures. Once it exceeds the safety threshold, we'll have Comrade Jiang come and clean it up."

He paused, then added, "What happened today is something for everyone here to keep to themselves; please don't spread it around."

Everyone nodded in agreement. Those who could get into this lab were all quite adept at maintaining secrecy.

Gao Xiaolan's eyes reddened again.

She turned around abruptly, her back to everyone, and forcefully wiped her eyes.

Only she knew what this meant.

Old Zhou no longer needs to endure nausea and pain to enter that laboratory. Those elderly scientists who were tormented by radiation will no longer need to wear that thick, stuffy protective suit when conducting experiments, will no longer need to race against time amidst radiation alarms, and will no longer need to have their bodies swollen and red for days after each experiment.

They can have more time to do research and suffer less.

Qian Weiguo walked to Jiang Zhiyu's side and lowered his voice, "Girl, you've worked hard."

Jiang Zhiyu shook her head. "It's only right."

"Host, their expressions are really interesting, like they've been struck by lightning."

"Shut up."

"That's for sure. That old researcher went in all aggressive, but came out with his legs trembling."

Jiang Zhiyu's lips twitched slightly, but she ignored it.

Gao Xiaolan took a deep breath, calmed herself down, and walked up to Jiang Zhiyu.

Her eyes were still a little red, and the tip of her nose was also red, but her gaze was very serious.

"Comrade, can I ask you for a favor?"

"you say."

Gao Xiaolan's voice trembled slightly, but she spoke each word with great effort.

"Several senior scientists in our lab have been exposed to nuclear radiation for years, and their bodies have been severely damaged. Some have red, swollen, and ulcerated skin all over their bodies, while others are already in wheelchairs and have difficulty even eating normally."

"They are still persisting in their research, but their health is deteriorating day by day. My mentor, Professor Zhou, would tremble so much that he couldn't hold the spoon when he ate, and he would wince in pain, yet he still insisted on going to the lab."

"Since you can remove nuclear radiation from the environment... could you also help check if their bodies might be...?"

She didn't finish her sentence, but the meaning couldn't be clearer.

The corridor fell silent, and everyone's eyes were on Jiang Zhiyu.
