Gu Yanzhi has always been in good health and rarely experiences menstrual cramps. This time, it's probably because she's been under a lot of stress lately, caught a chill in the extreme cold, and ate hot pot today.

Song Zhao thought about it and made another note in her mind: be careful to keep warm and not get cold. Eat less spicy food and get more rest.

Seeing Gu Yanzhi's pale face in pain, I felt extremely sorry for her.

He filled two hot water bottles with boiling water, placed them at Gu Yanzhi's feet, then turned off the light, got into bed, pulled Gu Yanzhi into his arms, and gently massaged her lower abdomen with his large hands.

Gu Yanzhi felt the warmth coming from her lower abdomen, and the pain subsided.

Gradually, her breathing became steady, and she drifted off to sleep.

The next day, when Gu Yanzhi woke up, she could no longer feel the pain. She was still in the same position as the night before, and Song Zhao's large hand was continuously transferring warmth to her.

Gu Yanzhi moved her feet and found that the hot water bottle under her feet was still warm, which meant that Song Zhao must have replaced it.

"Awake?" The first thing I heard was Song Zhao's slightly hoarse, deep voice.

Gu Yanzhi's movement startled Song Zhao, who then leaned down and kissed the top of her head.

"Did I wake you up?" Gu Yanzhi turned over, and the two lay face to face, their eyes meeting.

"No, I woke up a while ago, I just didn't get up," Song Zhao replied, unable to resist gently kissing Gu Yanzhi's forehead again. He just lay there quietly, without making any other movements.

When the two got up, the snow outside had stopped. Gu Yanlin had also gone out early with Building 10, leaving only Gu Yanzhi and Song Zhao at home.

After getting up, Gu Yanzhi first glanced at the thermometer, which read -60 degrees Celsius, indicating that the temperature had reached the lowest point of extreme cold.

After washing up, the two of them didn't sit at the dining table, but instead sat on the sofa and found a variety show to watch while eating.

The couple's breakfast consisted of a steaming bowl of congee with preserved egg and lean pork, soft steamed buns, and a small dish of pickled vegetables to accompany the congee. Gu Yanzhi also had a cup of brown sugar ginger tea that Song Zhao had brewed that morning placed beside him.

Looking at the brown sugar ginger tea, Gu Yanzhi frowned. Like Gu Yanlin, she disliked the taste of ginger. Thinking that Song Zhao was doing this for her health, she pinched her nose and drank it all in one gulp.

After finishing a cup of brown sugar water, Gu Yanzhi quickly shoveled a few mouthfuls of porridge into his mouth to suppress the unpleasant taste.

The congee with preserved egg and lean pork is delicious, with the lean pork tender and flavorful, and the preserved egg soft and melt-in-your-mouth. Served with pickled vegetables, it's even more delicious. A sip of congee, paired with a bite of steamed bun.

Gu Yanzhi ordered the steamed buns from a century-old shop in City C. She ordered over 1000 of each flavor, each carrying the unique taste of City C, a flavor Gu Yanzhi had loved since childhood. The sheer quantity required kept the century-old shop busy all day, even closing down, just to gather the number of buns Gu Yanzhi wanted.

After dinner, Gu Yanzhi and Song Zhao went up the stairs to the 17th floor to process the ginger seeds that had been soaked the day before.

The seeds need to be soaked in 50-degree warm water for 10-12 hours, but that time has already been exceeded, and I don't know if it will still work.

Desperate measures, I filled a planting pot with soil, dug holes, placed a few seeds in each hole, covered them, watered them, and added a few drops of nutrient solution. In no time, all the ginger seeds were planted.

They placed the planting pot in a sunny spot by the window, and then checked the ginger they had hydroponically grown the day before, adding some nutrient solution to it.

After confirming that the temperature in the growing room was between 20 and 25 degrees Celsius, which is the ideal temperature for ginger growth, the two of them, having nothing else to do, exercised for a while in the gym on the 17th floor.

Due to health reasons, Gu Yanzhi did not do any physical exercise, but practiced archery for a while to improve his accuracy.

Considering that Gu Yanzhi was still on her period and not suitable for activity, Song Zhao timed it carefully and didn't let her practice for long. The two of them went back upstairs and snuggled on the sofa to continue watching the variety show they had watched while eating breakfast.

For a whole week, Gu Yanzhi lived the same routine: getting up, eating, planting ginger on the 17th floor, exercising, watching variety shows, and eating again, without going out.

Gu Yanlin leaves early and returns late every day, only meeting briefly during dinner to chat and catch up on their day.

During this period, Song Zhao only went out once to collect the family's supplies, which were needed every five days. Perhaps due to insufficient preparation the first time, the second time they received supplies, in addition to compressed biscuits and steamed buns, there were also two boxes of self-heating meals and instant noodles.

After lying at home for so long, Song Zhao finally allowed Song Zhao to go out once her period was completely over.

The day after Grandma Zhang smashed the window with her son and daughter-in-law, everyone in Building 10 came to thank her. After learning about this incident, everyone was terrified, especially Sister Li, Xiao Lin, and the Gao couple. Fortunately, Gu Yanzhi and Song Zhao were there; otherwise, with only three elderly people, two infants, and a patient they didn't know well in the building, the outcome would have been very difficult.

At this point, there wasn't much of value to be had, and everyone knew that Gu Yanzhi's family had enough to eat and wear. So, they brought the firewood they had cut down the day before to thank them, but Gu Yanzhi refused to accept it. At this time, a bundle of firewood might be the lifeblood of a family.

She didn't need these things, and after saying it was just what she should do, she returned all the gifts.

After the snow stopped the next day, the task of everyone in Building 10 changed from logging to breaking ice and collecting supplies. The only things they needed for heating or daily life were the little bit they collected together on the second day of the extreme cold and the supplies distributed by the government.

Timber is also a very precious resource for everyone in Building 10.

Gu Yanzhi asked everyone to help take care of Gu Yanlin, who was the same age as Zhang Qian and the youngest besides Zhuang Nanyang. Neither of them had much social experience. Zhang Qian and Zhuang Nanyang had their parents to remind and guide them, but Gu Yanlin was all on his own.

Although Gu Yanzhi felt sorry for her younger brother, she couldn't keep him tied to her every moment. In the apocalypse, relying on anyone was not advisable, and who knew when they might be forced to separate.

Taking advantage of the fact that society is not yet in chaos during the early stages of the apocalypse, it is most important to seize the time to study and improve oneself. This is also why Gu Yanzhi wanted to let her younger brother go out alone.

The people in Building 10 are all very nice. Working with them ensures safety while also providing valuable experience and training.

Lin Cheng, the deputy captain of Squad 532, also came to express his gratitude with some gifts. That day, the squad had an emergency operation and called back those who stayed behind to take care of Chu Guodong. In just a few hours, something almost happened.

Gu Yanzhi also refused the things Lin Cheng brought. Regardless of whether Chu Guodong was there or not, she wouldn't stand idly by. These soldiers were always on the front lines of life and death when they were on missions, so it wasn't easy for them to accumulate any supplies.

After lunch, Gu Yanzhi and Song Zhao went back and took a short nap for an hour. Since they didn't have anything else to do, they decided to go out for a walk and see what the situation was like outside.
