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

Looking at those eager eyes, Jiang Zhiyu felt a little reluctant to refuse.

But she wasn't sure. The damage caused by nuclear radiation to the human body is continuous and penetrates to the cellular level, which is completely different from clearing environmental radiation.

"This... I'm not sure if it can be cured..."

Before she could finish speaking, Gao Xiaolan interrupted her hastily.

"It's alright, it's alright, it doesn't matter if you're unsure. You just need to take a look; even if it can alleviate their suffering a little, it will be good."

Before Jiang Zhiyu could even respond, she ran off, waving back as she went.

"I'll go push the teacher over here!"

The group had no choice but to stand still and wait.

Jiang Zhiyu asked Seventeen in her heart, "Do you think I can cure these people suffering from nuclear radiation?"

"In principle, the radioactive residue in their bodies is quite complex. Simple washing can only remove residues on the surface of the body; radioactive particles remaining inside the tissues and organs are difficult to eliminate. These particles will continue to release radiation and damage the body, and since they frequently enter high-radiation environments to conduct experiments, the damage will only increase."

"Let's bring him over in a bit and see how it goes. I can help you pinpoint the location of the microparticles inside his body."

"good."

In less than five minutes, Gao Xiaolan pushed a wheelchair over.

An elderly man wearing an old white coat was sitting in a wheelchair.

Jiang Zhiyu's heart sank after just one glance.

The old man was so thin he was unrecognizable; his oversized white coat hung on him like an empty sack. His hands were withered and bony, covered with dark red spots and ulcer scars. His knuckles were deformed and swollen, and even his hand, resting on the wheelchair, trembled slightly from the constant pain.

The condition on his face was even more severe. His cheekbones were prominent, and his skin was so thin it was almost transparent, revealing a network of dark purple blood vessels underneath. There were large patches of brown scars from radiation burns on his cheeks and forehead, and even his scalp had several irregular bald patches.

But his eyes were unusually bright, and though cloudy, they held a stubborn determination to never give up.

Even Jiang Zhiyu, an outsider, felt a pang of sadness watching this.

How many people like this are there in China, silently toiling away in the laboratory, seeking neither fame nor fortune, just to push their research projects forward?

When Old Zhou saw Jiang Zhiyu approaching, a hint of gentleness flashed in his cloudy eyes.

"Little girl, don't force yourself."

His voice was hoarse and dry, like sandpaper scraping against a tabletop.

"I've been like this for two or three years now, and I'm already very grateful that I can still go in and do experiments. The physical damage is irreversible; Xiaolan was just grasping at straws in her desperation."

"Teacher, please don't say that," Gao Xiaolan said, her eyes red-rimmed. "Let Comrade Jiang think of a solution, maybe..."

She didn't dare to continue.

Jiang Zhiyu squatted down and looked Zhou Lao in the eye.

"May I give it a try?"

Her voice wasn't loud, but her tone was very serious.

"Mr. Zhou, if you take good care of your health, you'll have more energy to serve the country, won't you?"

Old Zhou was taken aback, seemingly not expecting the young woman to say that.

Jiang Zhiyu stood up and glanced at Qian Weiguo.

Qian Weiguo immediately understood and turned to wave to the crowd in the corridor.

"Clear out Lab 7 and let this comrade go in and show it to Old Zhou. You all stop crowding around and go about your business."

"Gao Xiaolan, you go too. It'll just be me, Comrade Jiang, and Old Zhou going in here."

Although everyone was full of curiosity, no one dared to linger after Qian Weiguo gave the order, and they all returned to their posts with trepidation.

Qian Weiguo took the wheelchair armrests and pushed Old Zhou into Laboratory No. 7. Jiang Zhiyu followed behind and closed the door behind her.

The laboratory was small and simply furnished, with a lab bench, a few chairs, and experimental operating procedures hanging on the wall. In the corner were a thermos and several enamel mugs.

Jiang Zhiyu walked over, poured a glass of water, and took a very small amount of sleeping potion from her spatial storage and dissolved it in the water.

She walked up to Old Zhou with her water glass in her hand.

"Mr. Zhou, I'm not sure if I can cure him. Please have a glass of water first, and I'll take a look."

Old Zhou looked at her, readily took the cup, and drank it down in one gulp.

"I believe you, girl."

As soon as he finished speaking, his eyelids began to grow heavy. Before he could utter another word, his head tilted to one side, and he fell into a deep sleep.

Qian Weiguo was very perceptive. He got up, walked to the door, and stood guard with his back to Jiang Zhiyu.

Jiang Zhiyu found it somewhat amusing.

"Host, Commander Qian is getting better and better at handling things."

"Stop talking nonsense and get to work."

She first activated her poison-based supernatural ability, hovering her hands above Old Zhou's body, and a layer of pale purple light slowly covered his entire body. The radioactive residue on his skin was peeled away, neutralized, and cleared away bit by bit.

This step was quick.

The crucial part is what follows.

Jiang Zhiyu grasped Old Zhou's withered wrist, her poison-based supernatural power probing into his body along his meridians. Simultaneously, Seventeen activated her scan, marking the location of every radioactive particle accumulation in her mind.

Liver, lungs, bone marrow, thyroid gland...

Those tiny radioactive particles are embedded deep in the tissue like nails, releasing radiation day after day and eroding the surrounding healthy cells.

Jiang Zhiyu held her breath and carefully peeled, wrapped, and extracted those microparticles one by one.

The process is extremely meticulous and requires several times more mental energy than clearing environmental radiation.

After a full half hour, the last particle was completely removed.

This is just the first step.

Jiang Zhiyu took out a small bottle of spiritual spring water from her spatial storage, hesitated for a moment, and then poured out only a very small amount.

She also wanted to try whether the spiritual spring water could repair damaged cells.

The spiritual spring water slowly flowed down Old Zhou's lips.

The effect was almost immediate. The dark purple lines on Old Zhou's face began to fade, his atrophied skin gradually regained its fullness, and the edges of the ulcers on the back of his hands began to close up.

The changes are evident, but restrained. After all, the amount entering is extremely small.

"Host, thankfully you only fed him a small amount of spiritual spring water. Otherwise, the effect would be too incredible; Qian Weiguo would probably faint from fright."

"This is enough. He no longer needs to endure pain and can conduct experiments normally. The sources of radiation damage in his body have been eliminated. After a few days of rest, he will be no different from a normal person."

"But ultimately, these people's lifespans cannot compare to those of normal people. The damage has already been done and is irreversible."

Jiang Zhiyu nodded, tidied the table, and called out:

"Mr. Qian."

Qian Weiguo immediately turned around, his gaze falling on Old Zhou in the wheelchair.

He was stunned.

The emaciated, festering old man who had been wheeled in just half an hour earlier now looked noticeably better. His skin, though still aged, was no longer that sickly gray. The ulcers and scabs on the back of his hands had healed and were no longer a shocking sight.

His breathing became steady, no longer accompanied by heavy panting as before.

Qian Weiguo's lips trembled slightly as he looked at Jiang Zhiyu in disbelief.

"Is this... all done?"

Jiang Zhiyu nodded, "It should be ready by now."

Qian Weiguo was so excited that his lips trembled, and he couldn't utter a complete sentence for a long time.

"Little Jiang, I...I..."

"Alright, Mr. Qian, don't say anything more, I understand."

Qian Weiguo wiped away his tears, his voice choked with emotion.

"I thank you on behalf of Lao Zhou."

He was about to bow when he said that.

Jiang Zhiyu caught his bent-over waist.

"Mr. Qian, you're being too polite. We're all working for the country; there's no need to distinguish between us."

"Okay, okay, we're family, we're family." Qian Weiguo said repeatedly, then vigorously wiped his face twice.

How long will it take for him to wake up? What precautions should we take afterward?

Jiang Zhiyu thought for a moment and then told the truth.

"The damage is irreversible. I removed the residual radiation from his body, but the damage that has already been done cannot be undone. His lifespan will still be affected, but he will not experience those illnesses again."

"From now on, I will come regularly to clean up the environmental radiation for you, so you'll most likely not have to suffer like that anymore."

"That's good, that's good." Qian Weiguo breathed a long sigh of relief. "What about the other researchers who were exposed to radiation...?"

"It's all up to you, Mr. Qian. I've already started working on it; there's no reason to manage only one person. Let's arrange it in a bit. This is quite troublesome; let's take it one step at a time!"
