The three entered the house and simultaneously looked around.

But to the naked eye, neither Qin Zhihuai nor Qin Sheng and Fu Jingheng noticed anything amiss.

Qin Sheng closed her eyes and poured out her spiritual power, which covered the entire Qin family in the blink of an eye. She carefully sensed and searched inch by inch.

I had never thought about it in this way before and never paid attention to it, which is why I never discovered it. But now that I am basically certain that such a thing exists, it should be much easier to look for it.

That was Qin Sheng's original thought.

Half an hour passed, and although they had used their spiritual power to explore every corner of the Qin family's residence, including the relatively shallow underground area, they still couldn't find anything unusual.

No, still no.

Qin Sheng opened her eyes, a look of confusion flashing across them.

Fu Jingheng's expression shifted, a mixture of surprise and doubt: "Can't find it?"

"I can't find it." Qin Sheng shook her head, her gaze sweeping across the room again.

During Qin Sheng's search, Qin Zhihuai had been thinking intently with his eyes down. But upon hearing this, he suddenly raised his gaze.

He turned and walked towards the door.

He seemed to be in a hurry, clearly having thought of something.

Qin Sheng and Fu Jingheng exchanged a glance, then simultaneously followed him out.

As soon as Qin Zhihuai stepped out, he turned right and walked a short distance before stopping.

And in front of him at this moment was a greenhouse.

The greenhouse isn't very big, probably only about ten square meters. It's built with explosion-proof glass following the curve of the flower bed.

Because it was made of glass, the three of them could clearly see what was happening inside the greenhouse even without going inside.

In the very center of the greenhouse was a round table carved from rough jade, only reaching the height of a person's thigh. On the tabletop was carved a chessboard with the Chu River and Han Border, and some chess pieces were scattered on the board.

—That was a chess set made of ancient boundary stone, which Qin Sheng gave to Qin Yu as a gift when he first returned to the Qin family.

Since it was his granddaughter's first gift to him, and it was his beloved chess set, Qin Yu couldn't bear to take it to the laboratory to destroy it for research. Instead, he always carried it with him and would take it out to play with it from time to time.

Ever since Lu Yanqing was taken into the Qin family by Qin Zheng, the two have always used this chess set when playing chess.

Moving the gaze downwards, around the round table, there were four round stools made of the same rough jade material.

Three of the stools were empty, except for the last one, which had a small basket containing various kinds of yarn and knitting needles.

These belong to Gu Yueming.

I don't know what tweet she read, but she insisted that as a qualified good mother, she must knit a complete set of woolen hats, scarves, and clothes for her daughter by hand. Lately, she's been tinkering with this little basket every day.

But it's true, dexterity might be linked to intelligence. Almost half a year has passed, from September last year when the weather wasn't so cold until now, when winter is almost over, and Qin Sheng still hasn't received her mother's loving hat, scarf, and clothes.

Right now, there's only a crooked scarf in the basket that's not even as long as her forearm... let's just call it a scarf.

A smile flickered in Qin Sheng's eyes, but it was quickly replaced by a bone-chilling coldness.

Moving a little to the side, next to the innermost rough jade stool, there was an old pine wood tea table. It had probably not been used for a few days, and now it was covered with a thin red cloth to keep out the dust.

These were scenes she had seen countless times before, but seeing them again at this moment, Qin Sheng felt her heart beat a little faster.

Qin Zhihuai's face was equally gloomy.

But unlike Qin Sheng, his gaze was fixed on the various flowers and plants surrounding the greenhouse.

They lingered for a long time, especially on a patch of pale yellow orchids and a few green peonies.

Qin Sheng noticed and followed his gaze. When she saw the flowers, her eyes suddenly narrowed, and her voice deepened: "Where did these flowers come from?"

Qin Zhihuai's voice was a little hoarse as he answered her, "The green peony was a gift from my aunt, as were the two orchids. The rest were collected by me because I saw that my grandparents liked them."

Qin Sheng's fingers clenched tightly, and she couldn't speak for a long time.

Qin Zhihuai slowly came to his senses and knew that this was not the time to blame himself. After a moment of contemplation, he said, "It couldn't be my aunt."

Qin Sheng didn't think it was her, but even if it wasn't her, it was someone close to her.

And the most suspicious of them all...

"It's Xie Chao." It was Fu Jingheng who spoke.

Fu Jingheng gazed at the pale yellow orchids and green peonies, his eyes heavy with emotion.

"I heard Xie Fang mention it some time ago. His father has been tinkering with flowers all the time lately, and people often bring all kinds of orchids and peonies to his house."

Fu Jingheng had a deep impression of this, because Xie Fang complained for a while, saying that his father had either come to terms with reality or changed his ways, and hadn't come to fight for power with him for a long time, nor had he argued or thrown tantrums with his mother.

He spends all his time tending to flowers and plants, and they're all orchids and peonies that don't suit his temperament at all. People are starting to wonder if he's keeping a mistress on the side. Could it be that he's collecting these to please his mistress?

He talked a lot, but Fu Jingheng was so annoyed by him that he left and things quieted down.

“My mother likes peonies, and my grandmother likes orchids,” Qin Zhihuai said in a cold voice, glancing at the flowers again.

There was no need to try to verify anything further; Qin Zhihuai was certain: "It is Xie Chao."

Qin Sheng shook her head: "It's him, but it's not just him."

Qin Zhihuai turned to look at her: "What do you mean?"

Qin Sheng pointed to the other flowers in the greenhouse besides the orchids and green peonies: "Those flowers are growing quite well."

"If radiation can affect people, why are these flowers and plants, which are much more fragile than humans, unaffected?"

As Qin Sheng spoke, her gaze returned to the orchids and green peonies, her expression somewhat complicated: "That's because it contains radioactivity, not the soil or flowerpots that came in with the flowers, but the flowers themselves."

"These flowers were specially cultivated and are radioactive materials in themselves."

This radioactivity is very weak; it can only affect the area of ​​this greenhouse. Once outside the greenhouse, it is almost undetectable.

Not only is it weak, but it is also a radioactive substance that plants can accept, so that other flowers are not affected.

But people can't do that.

Even the weakest form of radiation, over a long period of time, will eventually cause some cells, chromosomes, and DNA fragments to mutate. These changes accumulate little by little until they reach a level that can affect human health.
