Nian'an and Nianxi often came to the workshop to help. With his outstanding mathematical talent, Nian'an quickly understood the equipment parameter settings and could even help the technicians with some simple calculations. Nianxi, on the other hand, served tea and water and took good care of everyone's daily needs. Seeing the family working together, the workers were greatly encouraged and voluntarily worked overtime to assist the technicians in debugging the equipment.

However, the debugging process was not without its challenges. The vacuum sealing equipment repeatedly failed to seal properly, and the low-temperature sterilization process struggled to precisely control the temperature, resulting in some trial-produced products failing to meet their expected shelf life. The German technicians repeatedly inspected the equipment but couldn't find the root cause, gradually becoming impatient.

Undeterred, Lin Wanqiu returned to her spatial dimension and carefully reviewed relevant technical documents, finally discovering the problem—the parameter settings of foreign equipment were based on the characteristics of their local ingredients, while the moisture and sugar content of domestic ingredients differed from those abroad, so directly applying the parameters would naturally not achieve the best results. She immediately informed the technicians of this discovery and suggested adjusting the equipment parameters according to the characteristics of domestic ingredients.

The technicians made adjustments with some skepticism, but during the next trial production, the product's sealing performance and shelf life were indeed significantly improved. The German technicians were very impressed with Lin Wanqiu, giving her a thumbs-up and exclaiming, "Ms. Lin, your professional knowledge and insight are truly admirable!"

After more than half a month of hard work, the automated production line was finally successfully debugged. Watching the machines smoothly complete a series of processes including cleaning, filling, sealing, sterilization, and packaging, Lin Wanqiu and Shen Tingzhou exchanged a smile, their eyes filled with exhaustion yet immense satisfaction. The new equipment not only significantly improved production efficiency, but also made the product packaging more exquisite and standardized, and extended the shelf life from the original three months to eight months.

To test the effectiveness of the upgraded product, Lin Wanqiu sent a batch of trial-produced strawberry jam and fruit and vegetable steamed buns to overseas customers. Half a month later, the foreign trade company brought good news: the customers praised the new product, not only renewing their orders but also increasing their purchases. In fact, new overseas distributors contacted them, hoping to become agents for "Natural Taste" products.

The news sent jubilation through the food workshop. Workers cheered around the new equipment, and villagers rushed to offer their congratulations. The village secretary exclaimed excitedly, "Wanqiu, Tingzhou, you two are truly outstanding! With this advanced technology, our 'Natural Flavor' will be even more competitive in the international market!"

Lin Wanqiu looked at everything before her, but she was not satisfied. She knew that technological upgrades were only the first step; to truly cope with the complex international market, she needed to master more international trade knowledge and rules. Just as she was pondering how to further improve her abilities, the jade pendant on her chest suddenly warmed slightly, and a new module slowly lit up on her spatial skill panel—the International Trade Knowledge Base.

Lin Wanqiu's heart stirred; she knew this was the space's timely assistance. With this knowledge, she was confident she could lead "Natural Flavors" to conquer the international market and achieve even greater success. Shen Tingzhou also realized that as the food workshop continued to develop, they would face increasingly more overseas regulations and trade frictions, making it imperative to acquire professional international trade knowledge.

Under the moonlight, Lin Wanqiu and Shen Tingzhou stood in front of the new factory, gazing at the fully operational production line, their eyes sparkling with anticipation for the future. They knew that the completion of the technological upgrade not only resolved their current predicament but also laid a solid foundation for the international development of the food workshop. The international trade knowledge they were about to acquire would become another powerful weapon for expanding into overseas markets, leading "Natural Delight" to a wider world.
