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

Upon arriving at the adjacent courtyard, before Wang Xia could even speak, the people who had come with Hu Ruomu saw the greenhouse and, as if they had discovered a priceless treasure, swarmed over. Their eyes lit up at the sight of the thriving cabbages, cucumbers, and other vegetables inside. One of the oldest-looking middle-aged men reached out and touched the plastic film, asking, "Where did this plastic film come from?!"

Hu Ruomu and Wu Jiangyong both looked at Wang Xia.

Wang Xia said, "Our military control committee's canteen bought it from a roadside vendor."

Undeterred, the older middle-aged man asked, "Could we meet that purchasing agent?"

Wang Xia replied, "He went home after get off work."

Hu Ruomu complained, "Old Wang, didn't I tell you yesterday?! Tell him not to leave this afternoon."

Wang Xia said, "Old Hu, he's already finished his job, why can't he leave?! Besides, the stuff is right here, and the remaining film is in the warehouse. If you want it, I'll go get it for you."

Hu Ruomu sighed, realizing he had been a bit too hasty and his tone had been somewhat harsh. He looked at the people who had come with him, forcing an awkward smile, and said, "Everyone, let's go inside and take a look!"

The five people who came with Hu Ruomu had been waiting for these words. The youngest one was the first to lift the greenhouse door and go inside. It was immediately clear that the inside and outside of the greenhouse were two different worlds. The five of them gave all the vegetables in the greenhouse a thorough check-up. About half an hour later, the five of them emerged from the greenhouse.

Hu Ruomu asked, "How is it?!"

The oldest middle-aged man replied, "Old Hu, you really have a lot of talented people here! As long as there are enough of these rainproof tarpaulins, this kind of planting can be promoted. Then we won't have to worry about not having vegetables to eat in the north during winter."

"The rest of these rainproof tarpaulins are in the warehouse. I'll go get them for you." With that, Wang Xia walked towards the nearby storage room. About seven or eight minutes later, Wang Xia returned to Hu Ruomu and the others, dragging a roll of plastic sheeting, and said, "The rest are here. Take them!"

One of the young men, wearing black-rimmed glasses, asked, "Can we take over this greenhouse?!"

Wang Xia glanced at Wu Jiangyong, then at Hu Ruomu, and said, "I can't make that decision. Why don't you come over the day after tomorrow morning? Come early and ask the person in charge of purchasing!"

The people who came with Hu Ruomu immediately gathered together and discussed it briefly. The oldest middle-aged man said, "Then we'll come over the day after tomorrow morning."

"Okay!" Wang Xia readily agreed and saw the person out of the military control committee.

After the jeep drove away, Wu Jiangyong asked, "Old Wang, when did this shed appear in the neighboring courtyard? How come I didn't know about it?!"

Wang Xia said, "It's been under construction for over a month now." Then she asked, "What?! You haven't noticed?!"

Wu Jiangyong replied, "I really didn't notice."

Wang Xia, with a Versailles-like expression, said, "It was all He Yuzhu's own mess. Old Xu said that next month, some vegetables from the greenhouse will be able to enrich our dining table."

Wu Jiangyong sighed and said, "Judging from the way things were just now, it looks like things are going to be tough."

After finishing work and leaving the Military Control Commission, He Yuzhu didn't rush home. Instead, he strolled around the streets. As he walked, he unknowingly reached Houhai Lake. Just as he was about to find a place to sit and rest, he felt a tap on his back. Turning around, he saw Lou Xiao'e standing behind him, smiling and greeting him, "Miss Lou, what are you doing here?!"

Lou Xiao'e replied, "I was bored at home, so I came out for a walk." Then she asked, "Aren't you at work? What are you doing here?!"

"I'm just a purchasing agent. I've completed my task. I'm just taking a stroll since I have nothing else to do." After saying that, He Yuzhu remembered what He Yushui had said last night and said, almost as if possessed, "Miss Lou, Yushui and I will definitely visit your house next Sunday."

Lou Xiao'e exclaimed excitedly, "You accepted my invitation?! That's wonderful!" Then she asked, "Can you walk with me now?!"

"Of course!" He Yuzhu said, and then accompanied Lou Xiao'e on a stroll.

Despite her privileged upbringing, Lou Xiao'e was a pitiful child. She should have been in school, but Lou Zhenhua, fearing for her safety, didn't send her. Instead, he found a school for her to attend by registering her name on the register and hiring a tutor to teach her at home. Lou Xiao'e used to have friends of similar age, but in the past two years, those friends had all gone abroad with their parents. Without playmates, Lou Xiao'e felt even more lonely. Then one day, she got lost and met He Yuzhu and his sister. Lou Xiao'e felt comfortable with them and unconsciously wanted to be close to them. Initially, she thought this feeling was just a hallucination. But after they ate hotpot together and returned home that day, Lou Xiao'e realized it wasn't a hallucination.

After walking around for over an hour, He Yuzhu escorted Lou Xiao'e home and was about to head home when a young man in a Zhongshan suit walked past him. He Yuzhu instinctively glanced at the young man, then scanned him with his divine sense. He saw a string of characters appear above the young man's head: Mei Chuandu (梅川渡梓). The background was gray. He Yuzhu was now certain that this person was most likely an enemy agent.

He Yuzhu immediately released his divine sense, keeping a close eye on Mei Chuan Du Zi. He then followed at a distance.

Mei Chuan Duzi was extremely cautious, stopping frequently to check if anyone was watching him from behind or around him. After walking for about half an hour, Mei Chuan Duzi entered a courtyard house. He Yuzhu, fearing he might alert Mei Chuan Duzi, didn't follow. He simply kept an eye on Mei Chuan Duzi with his divine sense, guessing that this three-courtyard house was Mei Chuan Duzi's hideout. After entering the courtyard, Mei Chuan Duzi greeted the people inside, acting as if they were very familiar with each other. Mei Chuan Duzi walked to the door of the west wing room in the backyard, took out his key, and opened the door. Although this west wing room was only a dozen square meters, it was surprisingly spacious inside. On the surface, this wing room looked no different from the main house in the courtyard, but there was a hidden room underneath. In the hidden room, besides several boxes, there was also a radio. He Yuzhu waited outside the courtyard for a few minutes, and seeing that Mei Chuan Duzi showed no intention of leaving, he finally left the alley where the courtyard house was located.

After walking for about twenty minutes, just as He Yuzhu was about to enter Nanluoguxiang, he ran into Zhang Qiang, the head of the local police station responsible for that area. He Yuzhu greeted him warmly, "Head Zhang!"
