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

The next morning, Song Zhaohong had just arrived at the station when Yao Qi followed. Yao Qi called He Yuzhu and Song Zhaohong into her office and asked, "Have you heard about what happened yesterday?!"

Song Zhaohong and He Yuzhu exchanged a glance, both looking bewildered. Song Zhaohong asked, "What happened?!"

Yao Qi said, "Yesterday, the municipal bureau and the military cooperated to arrest a large number of enemy agents who had been lying in wait."

Song Zhaohong said dismissively, "Haven't we arrested enough enemy spies over the years?! What's the big deal?!"

Yao Qi said, "The person we arrested this time is different from those we've arrested before. Do you remember our branch's Deputy Director Zhao Gu?!"

He Yuzhu replied, "I remember! How could I not remember?! I'd remember him even if he were ashes!"

Yao Qi said, "He and his wife were both enemy agents who had gone undercover. Moreover, Zhao Gu held a high-ranking position in the enemy's secret service."

At this moment, Song Zhaohong unconsciously looked at He Yuzhu and suddenly blurted out, "Did you already know?!"

He Yuzhu feigned ignorance and retorted, "What do I know?!"

"You little brat, keep pretending?!" After saying that, Song Zhaohong glared fiercely at He Yuzhu, complaining that He Yuzhu hadn't given him a heads-up.

He Yuzhu glanced at his watch and said, "Since you two are here, I should go home! I'm leaving now! I won't chat with you anymore." With that, He Yuzhu opened the door to Yao Qi's office and walked out. Watching He Yuzhu's retreating figure, Yao Qi asked, "Zhao Hong, do you think He Yuzhu really knows about this?!"

Song Zhaohong said, "There's nothing he doesn't know. He's not saying anything because he doesn't want us to get involved."

He Yuzhu left the police station and rode his bicycle into an alley not far from the branch office. He stopped in front of a courtyard house with a vermilion gate. He Yuzhu dismounted, walked to the door, and rang the doorbell. After a short while, the small window in the door opened, and a young man wearing glasses asked, "Comrade, who are you looking for?!"

He Yuzhu took out his work ID and handed it over, saying, "Director Zhang Hu sent me."

The young man took the work ID, looked at it, and returned it to He Yuzhu, saying, "Comrade, wait a moment, I'll go in and report." He then closed the small window. About five or six minutes later, the main door opened. The young man said to He Yuzhu, "Comrade, come in!"

He Yuzhu pushed his bicycle inside, parked it by the wall, and then followed the young man to a house, saying, "Director Zhang is waiting for you inside."

"Okay!" He Yuzhu responded and went into the house. Zhang Hu, who was busy with official business, looked up at He Yuzhu when he heard footsteps and said, "Please have a seat! I'll be there as soon as I'm done."

"Oh!" He Yuzhu responded, walking over to the wooden sofa and sitting down. About fifteen minutes later, Zhang Hu finished his work, walked over to He Yuzhu, sat down, and said, "Judging from your appearance, you've been living the good life lately!"

He Yuzhu replied with a smile, "Now the weather is favorable, and the country is peaceful and prosperous. Of course, I'm living a comfortable life!"

Zhang Hu pointed at He Yuzhu twice and said, "You little brat, always giving me high-sounding speeches!" Then, changing the subject, he said, "You're something else! You managed to mobilize everyone this time."

He Yuzhu laughed and said, "Boss, you're wrong about that. What do you mean I mobilized everyone?! I can only mobilize people within our station. Outside the Nanluoguxiang Police Station, who can I mobilize?!"

"I'm not going to waste my breath on you. Thanks to the leads you provided, we've uncovered several long-standing enemy spy networks within our ranks. The situation in Beijing, Tianjin, and the Northeast is now largely resolved. There are a few places in the south where the rounds aren't over yet, but they're basically no longer a threat." With that, Zhang Hu lit a cigarette and asked, "What do you want, kid?!"

He Yuzhu shook his head and replied, "No requirements!"

Zhang Hu stared at He Yuzhu for a few seconds and said, "We knew you would say that."

He Yuzhu then asked, "You didn't call me here today just to talk about this, did you?! If there's nothing else, I'll head back now." With that, He Yuzhu made to leave. Zhang Hu grabbed He Yuzhu, saying, "I haven't finished speaking, why are you in such a hurry?!"

He Yuzhu replied, "I'm in a hurry to go back and see my wife."

"Is that all you've got, kid!" Zhang Hu said, glaring at He Yuzhu. "I have an important mission for you this time."

He Yuzhu said, "I'm just a lowly police officer. What can I do?!"

Zhang Hu said, "If you were an ordinary policeman, you wouldn't have been able to bring back the enemy's mushroom bombs. This mission was assigned to you by your superiors."

He Yuzhu asked, "Can I refuse?!"

Zhang Hu shook his head and said, "No!"

He Yuzhu sighed and said, "I'm unlucky to have an uncle like you!"

Zhang Hu assumed He Yuzhu had agreed and was about to explain the situation when He Yuzhu suddenly stood up and continued, "I'm leaving now! Find someone else to carry out the mission!"

"Stop right there!" Zhang Hu shouted, halting He Yuzhu who was about to leave. He demanded, "Do you have any discipline at all?!"

He Yuzhu answered decisively, "No!"

Zhang Hu's face instantly tightened, unsure of what to say. After a few seconds of hesitation, Zhang Hu adopted a "I'm doing this for your own good" expression and said, "This mission is extremely important!"

He Yuzhu said, "You said the same thing last time. And you even said it would be the last time. I don't believe your nonsense! I'm leaving now! You can find someone else! If you really don't like me, you can fire me as deputy director and make me sweep the streets or clean toilets. If that's not possible, I can just go home and eat rice." With that, He Yuzhu left without hesitation.

Watching He Yuzhu's figure gradually disappear into the distance, Zhang Hu couldn't help but give a bitter smile. He walked to his desk, picked up the red phone on it, and made a call.

A little after ten o'clock in the morning, He Yuzhu returned home. Just as he was about to go to bed for a nap, he heard a knock at the door. Reluctantly, He Yuzhu put on his clothes, went to the door, and impatiently asked, "Who is it?!" before opening it. Seeing Zhang Hu standing there, He Yuzhu's face fell, and he asked, "What are you doing here?!"

Zhang Hu followed He Yuzhu into the courtyard and said, "What am I doing here?! You know perfectly well!"

He Yuzhu shook his head and said, "I don't know! And I don't want to know. You're not welcome in my home, so you should leave!"
