Glancing at him, Zhong Yuxiu finally noticed that something was wrong with him. He had only been caring about the child before; he didn't pay attention to Yan Rushan and ignored his courtyard.

"It should be fine..."

In the end, she hesitated. She had never taken care of a child and didn't understand the child's habits; she didn't even know how many times the child had woken up at night.

"They shouldn't get up too often at night, right?" Zhong Yuxiu made a final desperate struggle.

Wang Daya opened her mouth and repeated it several times before speaking. "Liji, they wake up three times every night. Sometimes the time is fixed, sometimes not. It depends on how much they eat and drink at night. Also, because they are growing, they sometimes wake up with a twitch at night, and then we need to coax them back to sleep."

"Draw out?" Zhong Yuxiu thought of the word first.

"Yes, other children also went through this; of course, not all children are like this, some won't even wake up after having a convulsion." After Wang Daya finished speaking, Zhong Yuxiu couldn't help but think deeply. The children were very healthy, and it was normal for them to grow taller after having convulsions.

After considering for a moment, Zhong Yuxiu nodded to indicate that she understood, and no longer insisted on taking the child back to take care of him.

Everyone went back to their rooms. Old man Yan Guofeng sat alone in the room for a while, then went to wash his clothes before going to bed.

After Zhong Yuxiu and Yan Rushan returned to the room, the first thing they thought of was the children's reaction to the pulling out; they looked up at the back of the person who was taking off his clothes and called out softly.

"Brother Yan."

"Hmm?" Yan Rushan turned around and looked at her doubtfully, "Are you sleepy?"

Yuxiu shook her head and sighed softly, "I'm not very sleepy. Comrade Wang just said that the children get twitchy when they fall asleep at night. I think they might be calcium deficient. Let's find a house in Province C and stew some bones and some calcium supplements for the children."

"Sure, we have a house in Province C." He had no objection to whatever his wife wanted to do. "Last year, when I bought a house, I asked someone to help me buy a house in Province C. It's quite large, and I gave you the property certificate and title deed at the time."

Zhong Yuxiu calmed down and recalled carefully, and she actually found the relevant memory, "The house was in the suburbs, not in the city."

"Yes, the suburbs are suitable for living. Living in the city is convenient, but it's really noisy, so it's not as good as the quietness of the suburbs." Yan Rushan added, "Besides, my friend said that house is not far from the city. It takes about ten minutes to get there. It's a village next to the provincial capital."

"That's fine. Let Grandpa and Comrade Wang go to Province C to relax tomorrow. We'll go check out the house and get anything we need and clean it."

Yan Rushan chuckled, walked over, put his arm around her shoulders, and coaxed her, "If Grandpa knew what we were going to do, he probably wouldn't go and have fun. We just arrived in Province C and will be here for at least five days. No matter what, Grandpa will focus on the children first. I don't have a place in Grandpa's heart anymore. All he cares about are his great-grandchildren. He knows his great-grandson is calcium deficient, so he has to do his best to supplement it for him. I guess he won't be able to take care of anything else."

This was the fact, and Zhong Yuxiu could not find any words to refute it.

"Just don't let Grandpa know, that's all. Just tell him we're going to visit your friends, and let Grandpa and his friends go play first. We'll meet up with them after we're done here."

"That's fine. I can borrow a car. It'll be useful in the next few days in the provincial capital."

The couple agreed, took off their coats and slept in each other's arms. There was a fan in the hotel and it wasn't on the top floor, so it wasn't too hot.

When she woke up, it was pitch black outside the window. Zhong Yuxiu rubbed her sleepy eyes and turned her head to look at the man sleeping beside her. He had long eyelashes, long eyeliner, a straight nose, thin and sexy lips, and a facial contour as sharp as a knife.

Such a man is destined not to be weak and easily controlled; on the contrary, he has a domineering personality, has his own way of doing things, and has very strict principles and bottom lines. He is cold and almost cruel in front of outsiders, but he is much gentler at home.

Zhong Yuxiu lifted the thin quilt, turned over and sat up, and sat down on the chair. When she woke up, her mind was clear and she could not fall asleep again. The night sky outside was full of sparkling stars, brighter and clearer than those in later generations.

Stars are rarely seen in later generations. Due to atmospheric pollution, the night sky is always covered with a layer of haze that is invisible to the naked eye.

Leaning back on the chair, she glanced at Yan Rushan again. He was still fast asleep, showing no signs of waking up. She idly opened her storage ring and took out some research materials she had done during her time in the interstellar space. She took these things and walked to the back of the bed, where there was information on space-time black holes.

It is not useful now, and I hope that I can research a method of traveling through space-time black holes in my lifetime; in interstellar space, the method of traveling through black holes is not popular, and each travel has certain risks, so it has been constantly being refined.

So many years have passed, and black hole travel has changed a bit, but it is still not truly safe.

Black holes can devour everything and are extremely unstable. Stability is crucial, and creating a shuttle path through them is incredibly difficult. In the interstellar age, black hole travel is a form of transportation, but not every small planet has it. Most interplanetary travel relies on spaceships.

She was very interested in black hole shuttle method and had studied it in depth. In the interstellar era, she failed to crack the true mystery of black hole shuttle method. In this era, it would be difficult for her to do so in her lifetime.

Zhong Yuxiu was a little discouraged for a moment, but she would try her best.

She took out her optical computer and searched for data on the black hole shuttle method to continue her research. She played a video of the operation of black holes that existed in the interstellar era. According to the subtle mysteries of the operation of black holes, she only found out some sporadic operating principles. Combining them with the operating principles that had been cracked in the interstellar era, she only discovered one-third of the essence of the mystery of the operation of black holes.

This is a long-term task that cannot be completed in a short time.

Estimating the time, it was past six in the morning when the first ray of sunlight shone through the window; she turned off the computer and put it into the storage ring, then took out a pen and paper to write down her observations.

Yan Rushan woke up in a daze and subconsciously touched the person next to him, but found nothing. He suddenly opened his eyes and found that there was no one around him. The quilt was cold and he didn't know when he woke up.

"daughter in law."

"daughter in law?"

Zhong Yuxiu quickly put away the paper and pen in her hand, turned around and responded, "I'm here."

Yan Rushan was obviously relieved. He quickly walked over and sat down on the stool beside her. "When did you get up? You didn't even call me."

"I didn't get up for long. I woke up and couldn't fall asleep again."

"Are you familiar with your bed?" This thought flashed through my mind.

Zhong Yuxiu shook her head, then nodded, "Maybe, I don't know, I just can't sleep."

"Maybe it's because we're new here." It looked like we couldn't stay in a hotel anymore. It would be best if we could move into our new home today. "After breakfast, tell Grandpa and the others that we're going to the suburbs and pack up and move in early."
