Is it a coincidence? After all, she is the fake daughter of the Xia family, not Xia Cheng and Su Yuerui's biological daughter, but Xia Qingqing.

"Buzz—"

The phone on the table vibrated, interrupting Xia Zhining's thoughts.

It was Ji Shuyun calling.

"Brother? What's wrong?"

Xia Zhining immediately answered the phone.

"Is there another case?"

On the other end of the phone, the usually calm Ji Shuyun's voice tightened a little: "Ningning, do you still remember the arsonist who set the fire with a kite?"

Xia Zhining responded, "Remember, Jiang Yunkai, Xia Cheng's confidant, the one who was almost silenced."

"What's wrong?"

Ji Shuyun's words made Xia Zhining's heart instantly rise: "I found something else."

"I found out that Jiang Yunkai opened a stir-fry restaurant near a paint factory in a small county town near Jiangcheng three years ago."

Xia Zhining complained inwardly when she heard this. Jiang Yunkai has both a cooking restaurant and a pet shop. His business scope is quite broad!

"He's definitely not opening a stir-fry restaurant to make money, right?"

——"Didn't you say that Xia Cheng gave you a few pages of manuscript fragments to research vaccines?"

Ji Shuyun dropped another bombshell: "I discovered that the time Jiang Yunkai's restaurant closed was only five days after Xia Cheng gave you the manuscript fragments!"

These words made Xia Zhining clench the chopsticks in her hand!

This means that the manuscript fragments in Xia Cheng's hand might have been obtained by Jiang Yunkai?!

And the source of the manuscript is a company or factory near the stir-fry restaurant?

Ji Shuyun: "And after he closed the stir-fry restaurant, he returned to Jiangcheng and opened a pet supplies store."

"I circled the point where the two timelines overlapped and asked him if he had helped Xia Cheng obtain a manuscript related to biological research."

"Jiang Yunkai's reaction was within my expectations. When I mentioned the manuscript, his first reaction was surprise, disbelief, and great confusion about how I knew about it."

After hearing these words, Xia Zhining's heart was already pounding. They were getting closer and closer to the truth.

Ji Shuyun asked, "Ningning, are you free this weekend? I have the weekend off."

"Let's go look around the area around that small stir-fry restaurant in the county town and ask if my mother has ever worked or lived there. We'll see if we can get any useful information or find someone she knows."

Xia Zhining immediately responded: "Yes!"

After hanging up the phone, Xia Zhining felt her hands still trembling with excitement.

The manuscript was obtained from Xia Cheng's mother by improper means. The incident of him being taken away by mistake was definitely not that simple.

The weekend came in a blink of an eye.

The county town where Jiang Yunkai had stayed before was called Yu County. It was surrounded by mountains and was very remote. There were many winding mountain roads that were very difficult to drive on, and it took two or three hours to drive there.

Xia Zhining and Ji Shuyun met at the zoo and set off for Yu County.

Xia Zhining also brought along a few small animals that could go outside, as if they were going on an outing.

Although the destination is remote, there are many mountains and trees, and the air is very good, which is suitable for the little ones to come out and exercise and breathe fresh air.
