Radioactivity

Hozuki Castle.

After Liao Wu returned, he went to find Natsuhi.

Natsuhi had trained with the Star. The Star was radioactive, and severe radiation had already accumulated within her body.

It was only because she was a jonin, and Chakra gave her a greater tolerance for error than ordinary people, that she had lasted this long.

If it weren't for the positive effects brought by Chakra, Natsuhi would already be like an ordinary person.

Due to prolonged exposure to radioactive substances, her white blood cell count would decrease and her immune system would weaken, eventually leading to death from infection or cancer.

Because of the "Star," Natsuhi had obtained the miraculous ninjutsu system known as the Mysterious Peacock Method. Yet because of the Star, her immune system had also deteriorated.

Liao Wu sat beside Natsuhi and implanted a Spore into her body.

If she stopped coming into contact with the Star from now on, the Spore's effects would gradually restore Natsuhi's immune system.

With the support of Liao Wu's Chakra, Natsuhi slowly recovered.

Soothed by Wood Style Chakra, Natsuhi's condition improved considerably. She touched her head in confusion. "I..."

Liao Wu sat on the hospital bed beside Natsuhi, stroking her hand as he explained, "It was the Star."

"The Star of your Hoshigakure is radioactive. Your immune system was damaged by your long-term exposure to radioactive material."

"Radioactive?!"

Natsuhi stared at Liao Wu in confusion.

Liao Wu then explained the harm radioactive substances could inflict upon the human body.

If the radiation level was low, below 0.25 Sv, it would only cause minor cellular damage. The body could repair it, and there would basically be no harm.

But beyond that range, it would harm the body.

Lymphocyte counts would drop, immunity would temporarily weaken, and one would suffer fatigue and
