The Courtyard House: The story begins with He Yuzhu beating up the White Widow.

Madam Jia Zhang looked at Jia Dongxu in terror and shouted, "I'm not going back to my hometown! If you want to go back, you can go back yourselves!"

"Mom! If you don't want to go back to your hometown, you'd better behave yourself for a while and not cause any trouble." Then Jia Dongxu said to Qin Huairu, "Huairu, buy some meat tomorrow, and we'll have a good meal together as a family." Then Jia Dongxu took out two yuan from his pocket and handed it to Qin Huairu.

"Hey!" Qin Huairu took the money and said, "I'll also buy some bones to make soup for Mom."

In the blink of an eye, another hour had passed. People who went to work outside gradually returned. As He Daqing and Liang Wanping entered the courtyard, they heard the neighbors discussing Jia Zhangshi's return. At first, He Daqing didn't pay much attention, but when the neighbors reminded him that Jia Zhangshi's daughter-in-law, Qin Huairu, had gone to their house to borrow meat, He Daqing's face instantly darkened, and he stormed home.

"Dad!" He Yushui, who had finished her homework and was playing in the courtyard, immediately ran to greet He Daqing when she saw him return. He Daqing, being a doting father, was happier than anything else to see his daughter. He picked up He Yushui and asked, "Daughter, were you bullied?!"

He Yushui was taken aback by He Daqing's abrupt question. She tilted her head, sizing him up, and asked, "Dad, are you worried I'll be bullied by the Jia family?!"

He Daqing said, "You're my daughter. If I don't worry about you, who will I worry about?!"

He Yushui kissed He Daqing on the cheek and said, "Dad, my brother's here! That good-for-nothing Jia Dongxu dared to bully me; my brother will definitely teach him a lesson!"

Following behind, Liang Wanping couldn't help but laugh at He Yushui's arrogant demeanor. He Yushui, acting like a little adult, said, "Aunt Liang, don't let my brother's seemingly simple-minded appearance fool you; he's actually quite shrewd! It's just that my dad gave him the nickname 'Silly Pillar.' Anyone who actually thinks he's a fool is the real fool." Then, He Yushui gave He Daqing a strange look and said, "Dad, why did you think of giving my brother such a nickname?! Don't you know that a foolish father makes a foolish son?! You say my brother is foolish, doesn't that prove you're even more foolish than him?!"

He Daqing reached out and tapped He Yushui on the forehead, saying, "You little brat, have you gotten too bold?! How dare you joke about your father?!"

"Hehe!" He Yushui grinned and said, "Dad, what I said is true! If it weren't for my brother's hard work, with that nickname 'Silly Pillar,' my brother would never have been able to get a wife in his life."

"Fine! Whatever you say goes?! You're right!" With that, He Daqing glanced at the Jia family out of the corner of his eye, thinking to himself, "If it weren't for Jia Zhangshi's commotion, I would have almost forgotten about the Jia family. Jia Zhangshi loves to curse the Jia family as having no descendants; I'll make sure your Jia family really does die out!"

He Daqing put He Yushui down, pushed the bicycle home, and then went into the kitchen. He Yuzhu brought the food to the table and said, "Dad, the food is ready. You can eat anytime."

"Hmm!" He Daqing responded, then asked, "Zhuzi, when I came into the yard, I heard the neighbors saying that the Jia family came to cause you trouble?!"

"They didn't really come to cause me trouble. It was more like they came to test me. To see if our family is round or square, and whether our family will become the second Yi Zhonghai, the blood bag for the Jia family." After saying that, He Yuzhu walked to the cabinet, opened it, took out a bottle of wine, and put it on the table.

He Daqing carefully considered He Yuzhu's words, then suddenly laughed and said, "I really didn't realize you were so quick-witted!

He Yuzhu said, "It's not that I'm smarter now, it's just that I was too lazy to use my brain before. Since the Jia family wants to play mind games, I'll play along to the end. I want to see who has the last laugh!"

He Daqing said, "Your father isn't dead yet! There are some things you don't need to do."

He Yuzhu understood what He Daqing meant, smiled, and without saying anything more, invited Liang Wanping and He Yushui to wash their hands and eat.

For the first few days after Jia Zhangshi returned, she was relatively well-behaved, living like a sow, eating and sleeping, at most grumbling a few times about Qin Huairu. But after about a week, presumably because her leg had improved, she began to show her true colors. Every day she either complained about Qin Huairu's cooking or cursed everything and everyone except her parents. She also forced Qin Huairu to work, begging for food from the neighbors. In short, no one in the courtyard wanted anything good for the Jia family. If Jia Zhangshi hadn't been still injured and staying home all day, she would have been dealt with long ago.

Time flew by, and it was two days before National Day. That morning, He Yuzhu had just returned to the Military Control Commission after buying groceries when Wang Xia called out to him as he passed by her office: "Zhuzi, come here for a second!"

"Oh!" He Yuzhu responded, walked into Wang Xia's office, and asked, "Aunt Wang, what's the matter?!"

Wang Xia gestured for He Yuzhu to sit down and said, "Zhuzi, National Day is just around the corner. Our military control commission is short-staffed. From this afternoon until the second day of National Day, you will patrol with the security team."

"Oh!" He Yuzhu readily agreed.

Wang Xia said, "Zhu Zi, the police station wants to transfer you there. I'd like to hear your opinion."

He Yuzhu asked, "Aunt Wang, do you really want me to be transferred there?!"

Wang Xia said, "It's up to you to decide this."

He Yuzhu thought for a moment and said, "Aunt Wang, I'm doing fine at the Military Control Commission, and I don't want to move."

Wang Xia chimed in, "Since you don't want to move, then stay here. Tell Grandpa Xu that the vegetables we eat these next few days will be picked from your garden."

"Oh!" He Yuzhu responded, then said, "Aunt Wang, if there's nothing else, I'll go back to the cafeteria now."

"Go on!" After sending He Yuzhu away, Wang Xia picked up the documents on the table and started reading.

After lunch, He Yuzhu went to the Public Security Section: "Section Chief Zhang, I'm here to report for duty on orders from Deputy Director Wang!"

Zhang Shun sized up He Yuzhu and said, "So, after all this time, you're the one I brought here?!"

He Yuzhu was taken aback and asked, "Section Chief Zhang, am I not allowed to come?!"

"Why are you calling me Section Chief Zhang?! Just call me Brother Zhang. It's not that you can't come, it's that I'm eager for you to come. Come on! I'll take you to get your weapons first." With that, Zhang Shun led He Yuzhu out of the security section office.

The military control commission's weapons depot was opposite Wu Jiangyong's office. It was converted from two west wing rooms. Upon entering the depot, Zhang Shun said to the custodian, Huang Weimin, "Old Huang, pick out a weapon for Zhu Zi."

Huang Weimin, who was reading, glanced up at Zhang Shun, took out his keys, placed them on the table, and said, "Take him in and choose for yourself!"
