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

He Yuzhu said, "Uncle Ye, don't you think this combination is strange?!"

Ye Guoliang said, "It's perfectly normal! A family of three, what's strange about that?!"

He Yuzhu asked, "How old is that child?!"

Ye Guoliang said, "Based on the birth date in the household registration file, she's about nine years old now." Then he asked, "What's wrong?!"

He Yuzhu said, "If my memory serves me right, I've seen that child before. But he looked older than nine. I suspect he was an adult, what we commonly call a dwarf."

Ye Guoliang frowned and said, "If it's really as you say, then there's something wrong with this family!" He picked up a cigarette case from the table, took out a cigarette, lit it, took a couple of puffs, and said, "They live in a large tenement. It might not be easy to keep an eye on them."

He Yuzhu, knowing Ye Guoliang's thoughts, said, "Uncle Ye, since we can't keep watch, let's find an opportunity to take them down one by one. The man is easy to deal with. We can arrest the woman when she goes to buy groceries. The only difficult one is the dwarf."

Ye Guoliang pondered for a few minutes, then said, "Go and call Deputy Director Yao and the others over. Let's discuss this."

"Okay! I'll go right now!" With that, He Yuzhu ran out of Ye Guoliang's office. Seven or eight minutes later, He Yuzhu returned with Yao Qi, Zhao Yong, and Zhou Qinghe. Yao Qi pulled up a chair and sat down, asking, "Old Ye, why did you have Zhuzi call us here?!"

Ye Guoliang looked at He Yuzhu and said, "Zhuzi discovered enemy agents again last night."

"What?!" Everyone present looked surprised and turned to look at He Yuzhu.

He Yuzhu didn't waste any time and directly recounted how he discovered the enemy agent to everyone present. After listening to He Yuzhu's account, Zhao Yong suddenly said, "A month ago, a theft occurred in that area. When I led a team to investigate, I saw this family. I didn't pay much attention at the time, but after hearing what Zhuzi said today, this family really does seem suspicious."

Yao Qi said, "We've always thought of playing the long game against enemy agents. But after so many years of in-depth investigation, the enemy agents still active are either deeply hidden or have just been awakened. I don't think it's suitable to play the long game against them. I suggest we make contact immediately and wipe them out before they realize what's happening."

Ye Guoliang said, "When Zhu Zi went to call you just now, I was thinking about this too. Now the problem is, how do we catch that child?!"

Zhao Yong said, "We can use the pretext of looking for a thief to approach the child and then arrest him."

"I agree with Lao Zhao's opinion," Zhou Qinghe echoed, adding, "But we need to consider how to apprehend that woman!"

He Yuzhu said, "We can arrest her on the way to buy groceries. If she doesn't go grocery shopping, we'll have to do it in the yard. But I'm afraid they'll incite the surrounding residents to obstruct us during the arrest."

Zhao Yong said thoughtfully, "That's a large, crowded courtyard. The situation is very complicated. I'm not afraid of anything else, but I'm worried that they might have accomplices in the courtyard."

"Yeah! It's hard to say what if they have accomplices!" Yao Qi muttered thoughtfully, looking at He Yuzhu.

He Yuzhu said, "How about we work with the subdistrict office to investigate the situation?"

"That's a great idea!" Zhao Yong was the first to agree with He Yuzhu's suggestion. The others thought about it and felt that this was the only feasible method at the moment.

After discussing it, the group decided that He Yuzhu and Zhao Yong would team up, along with two staff members from the neighborhood committee, to investigate the large courtyard. Ye Guoliang then went to the neighborhood committee and spoke with Wang Xia. Upon hearing that it involved enemy agents, Wang Xia didn't hesitate and immediately sent two officers who had been transferred from the military to accompany He Yuzhu and Zhao Yong to the courtyard.

"Oh?! Comrade Gao, what brings you here today?!" Old man Lin Asan, the manager of the courtyard, greeted the people from the neighborhood committee with a smile, then looked at the other three people beside him and asked, "And who are these three comrades?!"

Officer Gao said, "Old Lin, Song Kui's house in the front yard was burgled a while ago. The thief hasn't been caught yet, but based on the current situation, it seems to be someone they know. It's very likely the thief lives in a nearby yard. We're accompanying the police officers to make a visit today." He then asked, "Who's in the yard today?!"

Lin Asan replied, "Those who went to school and those who went to work have all left. Only some elderly people, housewives, and some children who are not old enough to go to school remain in the compound."

"Let's go! Let's go in and take a look!" After saying that, the cadre led the way into the courtyard.

From the moment He Yuzhu arrived at the entrance of the courtyard, he spread his divine sense outwards. He knew exactly how many people were in the courtyard and where they were located. When the group reached the backyard, He Yuzhu asked, "Uncle Lin, your courtyard is really a mess! Quite a few illegally built houses!"

Lin Asan said, "Who can argue with that?! Many residents lived here before Liberation. But when Liberation came, the homeowners ran away. Many families couldn't fit in, so they found some bricks and expanded the houses outwards. It was a last resort."

He Yuzhu then asked, "Are there any people who moved into your compound after Liberation?!"

"Yes! Of course we have them!" Lin Asan chimed in, introducing, "The Yu family in the front yard, the Bai family in the middle yard, and the Liu family in the back. But the Liu family moved here two days before Liberation."

Officer Gao asked, "Old Lin, are any people home at the Yu family, the Bai family, or the Liu family today?!"

Lin Asan replied, "Old Yu and his wife have both gone to work. Their three children have also gone to school. At Old Bai's house, only the elderly couple are there; the others have gone to work or school. At Liu's house, Liu Guishan has gone to work, and his wife has gone to buy groceries. She should be back in a little while. Their son is at home now."

Upon hearing that only the child was present, Zhao Yong secretly winked at He Yuzhu. He Yuzhu was about to speak when he used his divine sense to discover the dwarf hiding behind the door, watching them. He Yuzhu's mind raced; without a word, he burst through the door and rushed inside. The dwarf, caught off guard, was knocked to the ground. Without giving the dwarf a chance to get up, He Yuzhu went forward and knocked him unconscious.

Seeing this, Lin Asan asked, "What are you doing?!"
