Siheyuan, integrating everything, cultivating the city

Old man Li nodded from time to time and said, "This technology is really good. We can try to apply it in our own fields in the future."

After the demonstration, everyone expressed their confidence in the technology and thanked Li Xiangqian for sharing. Li Xiangqian felt relieved, knowing that his efforts were recognized and supported by everyone, which made him look forward to his future work.

With everyone's help, the work in the experimental field went smoothly. Li Xiangqian worked with his neighbors to apply the new planting method to the field. Their cooperation and communication made the whole process smoother and everyone's mood became happier.

At the end of a day's work, Li Xiangqian stood in the sunset, looking at the neatly arranged test fields, and a sense of satisfaction surged in his heart. Although it will take time to verify the effect of this technology, he believes that as long as everyone works together, better results will be achieved.

"Thank you all for participating today," Li Xiangqian said with a smile. "I hope we can work together to apply this technology to practice and achieve better results."

Everything in the courtyard was well managed by him. Li Xiangqian personally watered and fertilized the flowers, plants and trees in the courtyard, and even paid attention to the angle and direction of each leaf. The vegetable field in particular was the fruit of his hard work. He had carefully selected the seeds and cultivated them, looking forward to the joy of a good harvest.

However, on this day, Li Xiangqian discovered an unusual phenomenon. In the morning light, as he wandered around the field, he suddenly found some abnormal signs in the vegetable field he was so proud of. Some places on the green leaves became unusually mottled, and even a few leaves had been eaten away and were almost bare. This shocked Li Xiangqian, and he immediately realized that there might be some kind of threat hidden in it.

He approached the vegetable field and carefully observed the damaged areas. He could not help but feel anxious. He knew that pests in the vegetable field were the problem he least wanted to face. For him, this was not only a challenge to his hard work, but also an infringement on the courtyard he carefully maintained.

Li Xiangqian immediately went into the state of dealing with the problem. He walked around the vegetable field, carefully checking every leaf, trying to find traces of pests. He saw a few tiny black dots crawling on the leaves. Those insects seemed to be extremely cunning and quickly spread in the vegetable field. Li Xiangqian frowned, he knew that this battle had to be launched quickly, otherwise the whole vegetable field might suffer.

So he decided to take action. First, he carefully picked off the leaves that were infested with insects with delicate tools and placed them in a basket beside him. Then, he began to search the fields to find the source of the pests. Li Xiangqian has an almost paranoid love for his courtyard. He knows every inch of land and every plant here. He believes that as long as he observes carefully, he will definitely find a solution.

He continued to search in the vegetable field and eventually found some tiny insect eggs hiding in the soil. The presence of these eggs shocked him, as he knew that this meant that pests might have been quietly breeding in the soil. Li Xiangqian took quick action and began to clean the soil with special tools, picking out the eggs one by one and washing them with clean water.

After the cleaning, Li Xiangqian carried out a comprehensive disinfection of the vegetable field. He sprayed the soil and plants with natural agents to ensure that the pests would not have a chance to spread. Although the process was tedious, he completed each step meticulously, as if it was the final test of his years of hard work.

After dealing with these problems, Li Xiangqian sat on a bench in the courtyard and savored the experience. The courtyard was still quiet and peaceful, and the sun shone on his face, and his mood gradually calmed down. Although the insect infestation made him feel extremely tired, he knew that it was just a small battle between him and nature. His courtyard was still a place full of vitality, and despite the challenges, he was confident that he could restore its beauty and prosperity again.

However, Li Xiangqian felt a sense of uneasiness deep in his heart. The sudden appearance of the pest gave him a premonition of the unknown future. He knew that this was just a small episode in the courtyard, and there might be greater hidden dangers behind it. His heart was filled with the desire to explore the unknown, and he decided to get to know this land more deeply to ensure that it could always remain alive and vibrant.

Li Xiangqian walked lightly through the courtyard of the quadrangle and headed for the stream on one side. It was one of his favorite places, and the sound of the gurgling water always made him feel peaceful. He hoped that the clear water could give him some spiritual comfort and help him sort out the pest problem he had just faced.

The water flow was surrounded by several lush plants, full of greenery. A few yellow leaves floated on the water, reflecting the sunset glow in the sky. Li Qianqian squatted down and carefully observed the changes in the water flow. He put his hand into the water, feeling the coolness of the water, trying to let this natural touch pull his mind away from the troubles just now.

The feeling of uneasiness in his heart surged up like a tide. He knew that this pest infestation was just the tip of the iceberg, and there might be a bigger problem behind it that he had not yet realized. The discovery of those insect eggs made him think: Has the ecological balance of the courtyard been broken? He was worried that this might just be the beginning, and there might be more challenges waiting for him in the future.

"Xiao Li, what's wrong with you?" At this time, a gentle voice came from behind him. It was his old neighbor, Uncle Wang. He walked slowly towards him, holding a basket of fresh vegetables just picked from his own vegetable garden.

Li Xiangqian turned around and saw Uncle Wang's concerned expression. He smiled and replied, "Uncle Wang, I just found some insect pests in the vegetable garden, so I'm relaxing here now."

Uncle Wang frowned slightly, walked to the stream and sat down, unpacking the basket and said, "You are such a worrywart, kid. Insect pests are not a big problem, and they can be solved if handled properly. I am a little worried because you usually take too much care of that vegetable patch."

Li Xiangqian nodded. Although he felt a little relieved, the uneasiness still did not completely dissipate. He stared at the flowing water, his expression slightly fixed, as if he was thinking about something.
