Courtyard House: Primordial Chaos Pearl

Early spring in the outskirts of Beijing still carried a chill in the air, but the experimental fields outside the Hongxing Agricultural Machinery Industrial Park were already bustling with activity. Lin Dong held his six-month-old son, Lin Xiangyang, in his arms. The little guy, wearing tiger-head shoes, clutched a dried ear of wheat in his tiny fist, watching curiously as the precision seeders moved through the fields. He Yushui, wearing a thick coat, stood to the side, holding a telegram from Xinjiang, her eyes crinkling into crescents: "Feedback from Shihezi Farm has arrived. Our seeders can accurately sow seeds even in saline-alkali soil, with a germination rate 15% higher than manual planting. The Xinjiang Production and Construction Corps has placed an additional order for 300 units."

Amidst the roar of the seeder, Yan Jiecheng, dressed in blue overalls, ran over, holding up a metallic-looking component: "Brother Lin Dong, Sister Yu Shui! Look, I modified the seed tray pattern according to Uncle Yi's ideas, and now even small rapeseed seeds won't leak!" His face lacked its usual impetuousness; beads of sweat on his forehead conveyed a sense of accomplishment—he was now a key member of the R&D team, and last month he had won the factory's innovation award for his component improvement plan. Yi Zhonghai, leaning on his cane, followed behind, nodding and smiling as he looked at the component: "This kid is hardworking; he's more promising than I was in my youth."

No sooner had I finished praising them than the office phone rang urgently. It was the technician stationed in Thailand, his voice filled with anxiety: "Director Lin, it's terrible! Our combine harvesters are having problems in Thailand! The local climate is hot and humid, causing the engines to overheat and burn out, and the electrical circuits keep short-circuiting due to moisture. The customer has already suspended further orders!"

Lin Dong's heart sank. Southeast Asian orders were the key to Hongxing Factory's expansion into overseas markets. If they ruined their reputation, they would not only lose millions in payments but also miss out on the entire Southeast Asian market. He handed the child to He Yushui and immediately convened a meeting with the R&D team. "Hot and humid conditions are the core weakness," He Yushui said, unfolding a Southeast Asian climate map and circling the data for Thailand's rainy season in red. "Humidity often exceeds 90%, and temperatures consistently stay above 35 degrees Celsius. Ordinary waterproofing coatings and cooling systems simply cannot withstand it."

That night, Lin Dong entered the Chaos Space alone. He input the climate parameters of Thailand and the engine model into the space and activated the "Extreme Environment Simulation" function—a pale golden halo instantly transformed into a humid, hot airflow, enveloping the harvester model. More than ten waterproofing solutions failed one after another in the simulation, until he remembered the improved rubber trees cultivated in the Chaos Space: using purified natural rubber as sealing gaskets, the rubber was twice as tough as ordinary rubber and had stronger corrosion resistance; he also coated the circuit interfaces with a nano-level hydrophobic coating, which could form an "air film" that prevented moisture from sticking to the metal contacts. For heat dissipation, he changed the heat sink to a honeycomb shape, increasing the heat dissipation area by 30%, and paired it with a dual-fan intelligent temperature control system, and the temperature immediately stabilized within a safe range.

The improved plan was sent to Thailand overnight, and technicians, along with local workers, worked through the night to modify the machines. A week later, good news arrived: the adapted harvester operated continuously for twelve hours, with the engine temperature stabilizing at 75 degrees Celsius, and the electrical system functioning flawlessly. The Thai customer personally filmed a video showing the harvester operating smoothly in the rain, and he gave the camera a thumbs-up: "Hongxing Agricultural Machinery is even more durable than European machines!" Not only did they restore the original order of 500 units, but they also connected with distributors in Malaysia and Vietnam, tripling the number of new orders.

With the arrival of the spring planting season, the Hongxing Factory's production lines were running non-stop. Jia Dongxu's supporting factory also expanded its production, adding three new automated production lines specializing in seed metering devices for seeders and threshing drums for harvesters. "Director Lin, my factory has been rated as a 'Provincial-level Excellent Supporting Supplier'!" Jia Dongxu came to report the good news with the certificate in hand. Jia Zhangshi followed behind, carrying a tiger-head hat she had made for Lin Xiangyang. "This hat is soft, and it will keep the child warm." She no longer had her former tantrums; her face was full of simple smiles. Thanks to the dividends from the supporting factory, the Jia family was doing very well, and Banggeng had also become an apprentice in the factory and a regular worker.

The construction of the industrial park has also made new progress. The Beijing Machinery Industry Bureau approved new land quotas, allowing Hongxing Factory to build a research and development building and a school for the children of its employees. He Yushui, with her back slightly recovered, was busy designing the school's blueprints: "In the future, the workers' children won't have to travel far to school. We can hire teachers ourselves and open agricultural machinery technology interest classes to cultivate talent from a young age."

That day, Liu Haizhong arrived at the factory canteen carrying a basket of fresh vegetables. He now works as a kitchen helper, going to the market before dawn every day to pick out vegetables, and he's very efficient. "Director Lin, I heard the school for factory children is hiring teachers. My daughter graduated from teachers' college, could she give it a try?" He rubbed his hands together, his tone full of sincerity, all traces of his former bureaucratic airs gone. Lin Dong smiled and nodded: "Of course, let her participate in a trial lecture. If she has the ability, we'll hire her."

In mid-April, the first batch of modified harvesters for Southeast Asia was successfully delivered. Section Chief Wang from the Foreign Trade Bureau personally presented a banner that read, "Agricultural Machinery Goes Global, Chinese Products Bring Glory." News spread, and even provincial leaders came to inspect the industrial park, shaking Lin Dong's hand and saying, "You've not only helped farmers increase their income, but you've also earned foreign exchange for the country. Keep up the good work!"

As the sun set, Lin Dong held Lin Xiangyang in his arms on the observation deck of the industrial park. In the distance, in the experimental fields, precision seeders were still shuttling back and forth, and the seeds they had sown had already sprouted tender green shoots; the workshop was brightly lit, and the roar of machines rose and fell; He Yushui stood beside him, holding new research and development blueprints in her hand—a water-saving seeder designed for arid regions of Africa.

The little one babbled in Lin Dong's arms, his tiny hands grasping his fingers as he gazed at the distant fields. Lin Dong looked down at the child's innocent face, then up at the sunset, his heart filled with burning hope. He knew this was just the beginning. With the help of the Chaos Pearl and the support of those around him, Red Star Agricultural Machinery would not only travel throughout the country but also reach every field in the world, making the sound of machinery the prelude to a bountiful harvest and carpeting the earth with golden ears of wheat.
