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

Gao You didn't know how to answer He Yuzhu. After hesitating for a few seconds, Gao You sent something that looked like a tablet computer to He Yuzhu through the transaction system.

He Yuzhu opened the tablet computer following Gao You's instructions. Inside was a history book. The system was quite user-friendly, it seemed. Knowing He Yuzhu couldn't read Tianyu Star's language, it had already translated the text before transmitting it.

When the Dark Gate opened on Tianyu Star, their technology had reached the level of around 2035. This was a full eighty years different from He Yuzhu's timeline. He Yuzhu sent over a list. Gao You saw the list and, without hesitation, readily agreed. However, there was one condition: the martial arts techniques He Yuzhu gave him had to be genuine.

After negotiation, He Yuzhu first gave Gao You a portion of the martial arts techniques for verification. Gao You also gave He Yuzhu half of the materials. After both parties verified them and found no problems, they gave the rest to each other.

Although He Yuzhu possessed the "Martial Arts Manual," he had no intention of using its contents as a bargaining chip. Before his transmigration, He Yuzhu was a genuine fan of martial arts novels. In his quest to become a so-called chivalrous hero, he had even researched numerous martial arts manuals online, the most famous being the "Nine Yin Manual." Since his last spiritual upgrade, He Yuzhu's memories of his pre-transmigration days had become clearer. After a moment's hesitation, He Yuzhu wrote down the general outline of the "Nine Yin Manual," the first level of the internal energy cultivation section of the first volume, and the first level of the Nine Yin White Bone Claw. Fearing the recipient might not understand acupoints and meridians, He Yuzhu thoughtfully included a diagram of human meridians and acupoints. He Yuzhu quickly received half of the technical information from the other party.

He Yuzhu had initially thought it would take a long time for the other party to reply. Unexpectedly, just over an hour later, the other party was eager to complete the remaining transaction with He Yuzhu. He Yuzhu didn't think much of it. He wrote down the rest of the transaction from memory and sent it over.

Only after the transaction was completed did He Yuzhu learn from the system that the system had already verified the authenticity of the items being traded during the transaction. If the items were fake, the system would automatically block them, preventing the transaction from proceeding.

Having gained experience from the transaction, He Yuzhu contacted Xie Li again. Xie Li's planet was in the fourth year of what we perceive as an apocalyptic wasteland, and its reserves were almost exhausted. Xie Li was a warehouse manager at a small base, and the base manager was his grandfather.

In the apocalypse, gold was worthless. When Xie Li learned that He Yuzhu could procure the food he needed, he generously traded two tons of gold for two tons of self-heating rice. He Yuzhu wasn't the kind of unscrupulous businessman. After a moment's hesitation, he cleared out his two largest 45-foot shipping containers and filled them completely with self-heating rice. He Yuzhu also gave Xie Li several boxes of homemade braised dishes.

Having completed two transactions, He Yuzhu's "laziness" kicked in again, and he immediately exited the spatial dimension. "Knock! Knock! Knock!" Just then, a knock sounded at the door. He Yuzhu went to the door, opened it, and saw He Daqing standing there. He Yuzhu asked, "Dad, have you finished eating with Uncle Xu?!"

"Hmm!" He Daqing responded, walked into He Yuzhu's room, pulled up a stool and sat down, asking, "Zhuzi, did your report to the police station go smoothly today?!"

He Yuzhu replied, "They're all old acquaintances, how could things not go smoothly?!" Then he asked, "Dad, why are you asking this?!"

He Daqing said, "I'm a little worried about your sudden decision to work at the police station."

He Yuzhu said, "At the police station, I'm still in charge of purchasing supplies for the canteen."

Upon hearing that He Yuzhu was still in charge of the cafeteria's purchasing, He Daqing finally felt relieved. He Yuzhu continued, "Dad, your son isn't stupid. If we really encountered danger, wouldn't I run away?! Besides, with my skills, dealing with some petty thieves is a piece of cake."

He Daqing said, "Although I'm not that old, I don't want to see a parent outlive their child. Remember this, kid: don't be reckless, and don't rush into everything. If you really encounter danger, staying alive is the most important thing. As long as you don't die, even if you're crippled, I, as your father, can take care of you."

It's impossible for He Yuzhu not to be moved after hearing He Daqing's words. However, like He Daqing, neither of them were good at expressing themselves. He Yuzhu patted He Daqing's shoulder meaningfully and said, "Dad, don't worry! My job at the police station is temporary. I'll definitely find a way to transfer if I get the chance."

He Yuzhu chatted with He Daqing for a while, and the father and son smoked two cigarettes. He Daqing went to the kitchen to prepare dinner. After He Daqing left, He Yuzhu closed the door and went into his spatial dimension. He found several high-capacity outdoor portable power banks for camping, connected them to a photocopier, and began printing the materials Gao You had sent him.

Because the Dark Portal opened, the technological development of Gao You's planet stalled. So they took a different path. As for their original technological creations, they became commonplace. The information He Yuzhu wanted was top secret, some even being the most prized technologies of Western powers. But in Gao You's world, this information could be downloaded from any website.

Nothing happened that night. The next morning, He Yuzhu ate breakfast, said goodbye to his family in his uniform, and went out with his bicycle. As he passed the front yard, He Yuzhu deliberately stopped and said to Yan Bugui, who was watering the flowers, "Teacher Yan, I've recently heard some rumors circulating outside that are damaging my reputation. You're always well-informed in this area. I wonder if you've heard anything about them?!"

Yan Bugui's expression changed slightly when he saw He Yuzhu wearing a police uniform. Then, a smile spread across Yan Bugui's face as he asked, "Zhu Zi, why are you wearing a police uniform?!"

He Yuzhu replied, "The public security department was short-staffed, so the military control commission transferred me there." He then asked, "Teacher Yan, did you hear what I just asked you?!"

Yan Bugui said awkwardly, "Zhu Zi, I've been too busy with work lately. I really didn't notice."

He Yuzhu said, "Teacher Yan, if you don't know, then I'll pretend I asked for nothing. I'll have my colleague investigate later. If I find the person who spread the lies, I'll definitely send him in to keep Jia Zhangshi company." After saying that, He Yuzhu pushed his bicycle out of the gate of No. 95 courtyard.

After watching He Yuzhu leave, Yan Bugui rushed home in a panic: "Ruihua! Something terrible has happened!"

Yang Ruihua asked, "Old Yan, what's wrong?!"
