Siheyuan: Sap is the last word

He placed the copper coin on the threshold of Yi Zhonghai's house and kicked it gently with his foot.

"Yi Zhonghai, just wait and see!" He Yudong said in a low voice, then left quickly.

The next morning, Yi Zhonghai got up and opened the door as usual.

"Ouch!" Yi Zhonghai screamed and fell flat on his face.

It turned out that he was tripped by the copper coins on the threshold.

"Who the hell put that thing here!" Yi Zhonghai cursed angrily while rubbing his sore butt.

He picked up the copper coin on the ground, looked at it carefully, and found that it was an old copper coin.

"This copper coin..." Yi Zhonghai looked at the copper coin in his hand and was suddenly stunned.

He recognized this copper coin; it was the one left by He Yudong's grandfather!

"Could it be He Yudong who did it?" Yi Zhonghai's heart skipped a beat, and an ominous premonition came to his mind.

He remembered He Yudong's sinister smile last night and suddenly understood.

"He Yudong, you dare to plot against me!" Yi Zhonghai gritted his teeth and said, "I will make you pay the price!"

Yi Zhonghai endured the pain, stood up, and limped towards He Yudong's house.

He suddenly pushed open the door of He Yudong's house and walked in angrily.

"He Yudong, get out here!" Yi Zhonghai roared.

When He Yudong heard Yi Zhonghai's voice, he slowly walked out of the house with a playful smile on his face.

"Hey, uncle, what's wrong with you? Why are you so angry so early in the morning?" He Yudong said sarcastically.

"He Yudong, stop pretending!" Yi Zhonghai said angrily, "Did you put that copper coin at my door?"

He Yudong shrugged and said innocently, "Uncle, what do you mean by that? I don't understand."

"Stop playing dumb!" Yi Zhonghai roared, "Do you think I don't know it was you who did it? You did it on purpose, you wanted to hurt me!"

He Yudong laughed and said, "Uncle, you are such a joker. How could I possibly harm you? You are the elder in our courtyard."

"You dare to quibble!" Yi Zhonghai was furious. He rushed forward and grabbed He Yudong by the collar. "If you don't give me an explanation today, I will never let you go!"

He Yudong wiped the wine stains from his mouth, his eyes flashing with cunning. He dragged out a shabby wooden box from under the bed, opened it, and found it was filled with various parts, tools, and a yellowed notebook. This notebook was left by his father, and it recorded some strange inventions and designs, all of which were impractical. His father was ridiculed by the neighbors as "Crazy He".

He Yudong flipped through the notes, pages of drawings and formulas flashed before his eyes, and his father's obsessed eyes seemed to appear in his mind. He sneered. He used to think these things were rubbish, but now, he saw a glimmer of hope from them, a glimmer of hope for revenge.

He stopped at a page of blueprints for a "thunder bomb," a simple explosive device that was not very powerful but enough to create chaos and panic. His father had designed it to fry fish, but it ended up blowing up a pile of mud and getting himself covered in dirt.

"Frying fish? Humph, what I want to fry is people's hearts!" He Yudong smiled sinisterly.

He followed the instructions on the blueprint and began to assemble the "Sky-shaking Bomb". He carefully connected the wires and filled the gunpowder, as if he was performing a sacred ritual. His movements were skillful and precise, as if he was born with this skill.

It was late at night, and the courtyard was silent. He Yudong sneaked out of the house with a "thunder bomb" wrapped in black cloth in his hand. He came to the door of Yi Zhonghai's house, looked around, and after making sure that no one was there, he placed the "thunder bomb" at the door of Yi Zhonghai's house.

He lit the fuse and quickly hid aside. The fuse burned with a hissing sound, emitting a faint light that was particularly eye-catching in the darkness.

"boom!"

A loud bang broke the tranquility of the courtyard. A big hole was blown in the door of Yi Zhonghai's house, and wood chips and dust flew everywhere.

The residents in the courtyard were all awakened and ran out to check the situation. Yi Zhonghai rushed out of the house with his clothes on, looking at the blown-up door with horror.

"What happened? Who did it?" Yi Zhonghai roared angrily.

He Yudong hid in the crowd, looking at Yi Zhonghai's frustrated look, and felt secretly happy.

"Yi Zhonghai, you have come to this day!" He Yudong laughed secretly in his heart.

The crowd was talking about who did it. Some said it was a thief, some said it was an enemy, and some said it was a prank.

"It must have been He Yudong who did it!" Sha Zhu suddenly shouted, and he said with certainty, "Who else would do this except him?"

Everyone's eyes were focused on He Yudong. He Yudong was shocked, but he quickly calmed down and pretended to be innocent.

"Shazhu, stop slandering me! How could I do such a thing?" He Yudong retorted.

"Stop pretending! Everyone knows about your feud with that old man!" Sha Zhu pointed at He Yudong's nose and cursed.

"Silly Zhu, stop trying to sow discord here!" He Yudong said angrily.

The two quarreled fiercely, and everyone began to suspect He Yudong.

Yi Zhonghai looked at He Yudong with cold eyes. He gritted his teeth and said, "He Yudong, just wait for me!"

At this moment, the door of the old man's house was opened again, and a woman with disheveled hair rushed out, holding a kitchen knife in her hand, and rushed towards He Yudong.

"He Yudong, you beast! I'm going to kill you!"

He Yudong staggered to the bedside and dragged out a shabby wooden box from under the bed. The box was locked, and the keyhole was rusty, which showed that it was very old. He struggled to poke it with a piece of wire for a long time, and finally with a "click", the lock opened.

The box contained no gold or silver treasures, nor any heirlooms, but a bunch of random little things: a few yellowed photos, a few wrinkled letters, and a worn notebook. He Yudong flipped through the photos and saw a young woman holding a baby in her arms, smiling brightly at the camera. The woman's face was vaguely visible, and her eyebrows and eyes were somewhat similar to He Yudong.

"Mom..." He Yudong muttered to himself, with a hint of tenderness in his eyes. But he quickly calmed down, threw the photo back into the box, and picked up the notebook. The cover of the notebook had fallen off, revealing the yellowed paper inside. He Yudong opened the notebook, and lines of beautiful handwriting came into view.

This is his mother's diary.

The diary recorded the love story between his mother and his father, as well as the brief happy time of their family of three. On the last few pages of the diary, the handwriting became scribbled and messy, full of despair and pain.

"Yudong, I'm sorry. I can't take care of you anymore..."

He Yudong's nose felt sore and his eyes became moist after reading this. He closed his eyes tightly, took a deep breath, and forced back the tears.

"Mom, don't worry, I will definitely avenge you!" He Yudong said gritting his teeth, his eyes filled with hatred.

He closed the notebook and put it back in the box, which he then locked and tucked back under the bed. He walked over to the table, picked up the bottle of wine, and took another swig.

"Yi Zhonghai, you old bastard, you killed my mother, I will make you pay the price!"

Under the influence of alcohol, He Yudong's thoughts became confused. He recalled his mother's painful expression before her death, his lonely childhood, and Yi Zhonghai's hypocritical face, and the anger in his heart burned fiercely.

He staggered to the wall, picked up a rusty kitchen knife, and waved it in the air.

"Yi Zhonghai, I will kill you! I will kill you!"

He Yudong's shouting sounded particularly harsh in the silent night.

Early the next morning, Yi Zhonghai came to the deaf old lady's house and told her about He Yudong's crazy behavior last night.

"Deaf old lady, you see, He Yudong is simply a lunatic! If he continues like this, something bad will happen sooner or later!" Yi Zhonghai said with a worried look on his face.

After hearing this, the deaf old lady's face became serious. After thinking for a moment, she said, "Yi Zhonghai, this matter really can't be delayed any longer. We must find a way to stop He Yudong."

"But what can we do?" Yi Zhonghai asked helplessly.

The deaf old lady's eyes flashed with a gleam of light, and she said: "I have an idea..."

Just then, there was a sudden commotion in the yard.

"Silly Zhu! What are you doing? Let me go!"

"Qin Huairu, you bitch! How dare you cheat on me with another man..."

Yi Zhonghai and the deaf old lady looked at each other, thought something was wrong, and quickly got up and walked out.

I saw Sha Zhu grabbing Qin Huairu's hair and punching her in the face. Qin Huairu's face was already covered in blood and she cried for help from the people around her.

"Shazhu, are you crazy? Stop it!" Yi Zhonghai shouted loudly.

Sha Zhu acted as if he didn't hear anything and continued beating Qin Huairu.

"Shazhu! If you don't stop, I will call the police!" the deaf old lady also said sternly.

Sha Zhu finally stopped, but he was still holding Qin Huairu's hair tightly, his eyes full of anger and despair.

"Qin Huairu, why did you do this to me? I was so good to you, why did you betray me?"

Qin Huairu cried bitterly but couldn't utter a word.

At this moment, He Yudong suddenly walked out of the crowd, holding a kitchen knife in his hand...

He Yudong dug out a worn-out wooden box from under the bed, which contained the "treasures" he had accumulated over the years. They were called treasures, but in fact they were just some parts and tools he had "taken" from the factory, as well as some scrap copper and iron he had collected. He searched for a while and pulled out a greasy iron box from a pile of miscellaneous items.

He opened the box and found some small parts and a rusty metal tube. He Yudong carefully took these things out and placed them on the table. He squinted his eyes and looked at these parts carefully, with a strange smile on his face.

"Yi Zhonghai, don't you like to pretend to be a good guy? I'll let you taste what it's like to be a good guy!" He Yudong whispered to himself.

He spent a whole afternoon assembling these parts. Finally, a simple thing similar to a small catapult appeared on the table. Although it looked rough, He Yudong was confident in his craftsmanship. He was a technical backbone in the factory when he was young, so this little thing was no problem for him.

As night fell, the courtyard was quiet. Every household had lights on, except Yi Zhonghai's, which was completely dark. Yi Zhonghai was in a bad mood today and went to bed early.

He Yudong quietly slipped out of the house, holding his homemade "weapon" and a small bag of stones wrapped in rags. He crouched down and came to the window of Yi Zhonghai's house. After confirming that there was no one around, he smiled sinisterly and put a stone into the leather bag of the slingshot.

"Old thing, let me show you how powerful I am!"

With a whoosh, the stone flew out with a sound of breaking through the air and hit the window of Yi Zhonghai's house accurately.

"Snapped!"

The sound of breaking glass was particularly harsh in the silent night.
