There weren't many people in the sleeper carriage at this time.

They got into the car and settled in, but the car hadn't started moving yet.

The three siblings, nicknamed "Little Soft Candy," looked out the window with curiosity, glancing at anyone who passed by their sleeper berth.

Soon after, the car started moving.

The three adorable children were overjoyed: "It moved! It moved!"

"Mommy, are we taking the train back?" Little Softie thought taking the train would be fun.

Ruan Yunxi nodded.

Little Gummy smiled and said, "Mommy, I like riding the train."

"If there's a chance in the future, I'll have your dad take you on more train rides!"

"Yay!" Little Softie immediately went to her father to act cute. The father and daughter sat on the dining bench by the window and chattered away.

The little candy charmed her father so much that he wanted to take her on the train every day.

Once on the train, there was nothing else to do, so Ruan Yunxi told the nanny to rest for a while.

The old woman was getting on in years and couldn't take much physical exertion. Seeing that the three children were being looked after, she lay down on the lower bunk and fell asleep almost immediately.

The little candies were quiet and didn't make a fuss; they even spoke in hushed tones.

When the flight attendants pushed out a cart selling food and drinks, the three siblings, including Little Soft Candy, stared intently, surprised that there was food for sale on the train.

They had no money, and they all looked at Ruan Yunxi.

Gu Weizhou also looked at Ruan Yunxi, and then at the stroller.

With four pairs of eyes watching her, Ruan Yunxi, who was in charge of the money, couldn't pretend not to see them, so she immediately relented: "Choose whatever you want to eat."

"Thank you, Mom!" The three little gummy siblings each chose one item.

Ruan Yunxi looked at Gu Weizhou, who smiled and, out of courtesy, chose one of Ruan Yunxi's favorite dishes.

Ruan Yunxi paid the bill, and the train attendant continued selling melon seeds, peanuts, biscuits, and delicious candies from her cart to other carriages.

"Mommy, eat!" Little Gummy chose peanut candy.

The youngest son chose roasted pine nuts.

The second child chose the small twisted dough sticks.

They all gave the snacks they had chosen to Ruan Yunxi.

Gu Weizhou chose melon seeds and even helped peel them, leaving only the kernels for her.

Ruan Yunxi gave the children a taste of the snacks they offered, saying, "You can eat them yourselves."

"Give this to the nanny!" They even knew to save some for the nanny.

The old woman, who was still awake, felt a warm glow in her heart upon hearing this.

These three children weren't spoiled in vain; they even know to think of her.

Besides snacks, the train also sells rice, noodles, and stir-fries; you can eat as long as you have money.

Ruan Yunxi and her family brought some food, but the children wanted to try the food on the train, so Ruan Yunxi bought one for each of them, and the children ate it with great relish.

The three adults ate the food they brought themselves, such as boiled eggs cooked by Sister-in-law Sheng. It would be a waste if they didn't finish them.

The three children had big eyes but small appetites, and Gu Weizhou cleaned up all the food they couldn't finish.

When the three children woke up after a nap on the train, it was almost time to get off.

Three adults, each holding a sleepy-eyed child.

Gu Weizhou was carrying the youngest child, who was the heaviest; neither Ruan Yunxi nor the nanny could carry him.

Ruan Yunxi was holding Xiao Ruantang, while the second child was being led by the nanny. The second child felt sorry for the nanny's old age and wanted to walk by himself.

After they exited the train station, Brother Gu drove up to pick them up: "Here!"

Ruan Yunxi said to Xiao Ruantang, "This is your uncle, remember to greet him!"

Little Gummy nodded and said in her childish voice, "Hello, Uncle!"

The eldest son also spoke up: "Hello, Uncle!"

The third child followed up: "Hello, Uncle!"

Looking at his three adorable and charming nephews and nieces, Gu Weihai could understand why the old couple doted on these three grandchildren so much, making them pale in comparison to their own children.

Now it seems Gu Weihai has solved the case.
