Siheyuan: tomb robbing? I am serious about hunting.

Scattered on the ground, it looked like a thin layer of silver frost. Wanqiu walked slowly along the ridge of the field and soon arrived at the mulberry garden. She walked to the mulberry tree wrapped with plastic rope and shone the flashlight, only to find that the plastic rope was gone. Instead, there was a small glass bottle. The bottle was transparent and half filled with a light yellow liquid, which looked like some kind of potion. Wanqiu wondered, who took away the plastic rope and left such a glass bottle? She stretched out her hand and was about to pick up the bottle when she heard footsteps behind her, "rustling", which sounded particularly clear in the quiet night. Wanqiu was startled and turned around abruptly, shining the flashlight in the direction of the sound. Under the light, Shen Zhiyuan's figure gradually became clear. He was wearing a thin coat and holding a flashlight in his hand. He had obviously just come out of the guesthouse. Wanqiu breathed a sigh of relief and asked, "Technician Shen, why are you here?" Shen Zhiyuan walked up to Wanqiu, his eyes fell on the glass bottle in her hand, and said with a smile, "That is nutrient solution for silkworms. I put it here this afternoon. I saw that this mulberry tree was not growing well, so I thought of trying the nutrient solution to see if it could improve it." Wanqiu's hand holding the bottle paused. She looked at Shen Zhiyuan and asked in confusion, "How do you know about this mulberry tree?" Shen Zhiyuan did not answer her question directly, but changed the subject: "Comrade Wanqiu, you have known about the technology of raising silkworms in plastic greenhouses for a long time, right?" The moonlight shone on Wanqiu's face, and she could clearly see the fine lines at the corners of her eyes, which were the marks left by years of hard work. She was silent for a moment, then looked up at Shen Zhiyuan with a hint of resignation. "So what if you know? The team doesn't allow these new things. As a technician, you've only paid lip service to improving varieties, but haven't you actually helped us solve practical problems?" Shen Zhiyuan suddenly smiled. He pulled a neatly folded sheet of paper from his pocket and handed it to Wanqiu. "Comrade Wanqiu, you misunderstood me. I have complete information on greenhouse silkworm rearing. It details how to construct plastic greenhouses, temperature and humidity control techniques, and the key points for raising and managing silkworms in greenhouses. I've also brought some improved mulberry seeds, all tested by the Agricultural Science Institute and suitable for our local soil and water." Wanqiu took the paper, carefully unfolded it, and studied it carefully in the moonlight. The information was incredibly detailed, with clear diagrams of the greenhouse structure. Compared to what she had seen in the newspaper, it was much more comprehensive and professional. Her heart was filled with excitement, and her hands were shaking. But just then, Shen Zhiyuan spoke again, "But I need a favor from you—find the people in this village who are secretly growing out-of-season vegetables." Wanqiu's heart skipped a beat. She looked up at Shen Zhiyuan, puzzled. "What do you mean by that?" Shen Zhiyuan sighed and said, "The county recently received reports that some villagers are secretly growing out-of-season vegetables and selling them in town. This violates the regulations of the collective economy. My mission in this village, besides guiding everyone in silkworm rearing, is to investigate this matter. I know you're well-connected and well-informed in the village, so I'd like to ask for your help in finding them." Wanqiu's mind flashed back to Aunt Wang, who was selling silkworm medicine in the threshing ground at the foot of the mountain, and the old silkworm-rearing book she had hidden under her bed. She knew that Aunt Wang's covert selling of silkworm medicine was risky enough, but if anyone else was caught secretly growing out-of-season vegetables, they would surely face severe punishment. She hesitated, unsure whether to help Shen Zhiyuan. If she helped, it might harm the villagers; but if she didn't help, Shen Zhiyuan might not give her the greenhouse silkworm breeding information and improved mulberry seedlings, and then her wish to increase the mulberry silkworm harvest would be ruined. Wanqiu stood there, holding the greenhouse silkworm breeding information tightly in her hand, her heart was extremely conflicted. Under the moonlight, her figure looked particularly lonely. The improved mulberry trees not only have a high leaf yield, but also better quality leaves, which are more suitable for silkworms to eat. "Just as Zhou Tiezhu was about to speak, Wanqiu said first: "Technician Shen, our village has always planted this kind of old mulberry tree. We have been planting it for decades and we are used to it. And we don't know much about the improved varieties. What if they are not adapted to the water and soil here after the modification, and the mulberry trees die, the loss will be huge. I think the old method is safer. "In fact, Wanqiu also knew the shortcomings of the old mulberry tree. She had read about the grafting and improvement of mulberry trees in that old book before, and she wanted to try it, but she knew that Zhou Tiezhu was conservative and would definitely not agree. Moreover, the people in the village might not be able to accept the new variety, so she said that. After listening to Wanqiu's words, Zhou Tiezhu nodded repeatedly: "Yes, Technician Shen, Wanqiu is right, let's not take the risk. Although the old variety has a lower yield, it is at least stable and not prone to problems. "Shen Zhiyuan looked at the two of them, smiled helplessly, and stopped persuading them. He knew that changing the villagers' minds would not happen overnight, and it would require slow guidance. After lunch, Zhou Tiezhu asked Wanqiu to take Shen Zhiyuan to the village guesthouse to rest. The guesthouse was an old house in the village with only a bed and a table in it, and the conditions were very simple. Shen Zhiyuan didn't mind. He put down his luggage, sat at the table, took out a pen and paper, and began to record what he observed in the mulberry garden in the morning. Wanqiu stayed in the guesthouse for a while, then got up and prepared to leave. She also had to go to the mulberry garden to see the situation of the silkworms. Shen Zhiyuan called her, took out a small notebook from his pocket, and handed it to Wanqiu: "Comrade Wanqiu, this is some technical points of silkworm rearing that I have compiled. You can take a look at it. It may be helpful to you. "Wanqiu took the small notebook and opened it. It was filled with dense words and some illustrations, such as the morphology of silkworms in different growth stages, identification methods of diseases and pests, etc. She was moved and said "thank you" to Shen Zhiyuan, then took the small notebook and left the guesthouse. In the afternoon, Wanqiu was busy in the mulberry garden. While feeding the silkworms with mulberry leaves, she would take out the small notebook given by Shen Zhiyuan from time to time to read it. The content in the small notebook was very practical and solved many problems she encountered in the process of raising silkworms. The more she read, the more she felt. Knowing that Shen Zhiyuan was a technician with real skills, Wanqiu had a better impression of him. After dark, Wanqiu returned home, had dinner, and waited until her mother and brother fell asleep. However, she was still thinking about the mulberry tree wrapped with plastic rope. In the afternoon, when she was busy in the mulberry garden, she paid special attention and found that the plastic rope was still there, but she always felt uneasy and wanted to go and have a look again. So, Wanqiu quietly got up, took a flashlight, and walked out of the house. The village was very quiet at night, with only the occasional barking of dogs and the chirping of insects. The moonlight was bright,
