The situation having completely stabilized, Ding Yun no longer caused any major trouble. After all, her mission of imprinting her mark was complete, and there was no longer any need for her to stir things up.
Of course, she didn't leave immediately.
It wasn't that she didn't trust the original body's sister or parents. The main reason was that there was still one world that wasn't settled.
A significant amount of resources had been invested in the early stages.
It would be too much of a pity to give up now.
Therefore, from then on, Ding Yun lived a reclusive life, dedicating all her efforts to assisting Zhu Yunying, who was currently in a parallel world.
With the full support of the world's richest person, whose technological level was sixty years ahead of her own world, it was difficult for Zhu Yunying not to rise to prominence.
For the first two years, she wholeheartedly assisted in cultivating the high-yield crop seeds that Ding Yun had given her, which she claimed were left to her by her dying master.
These experiments were successfully conducted in the county.
Not only did she gain significant prestige and honor, but she was also promoted to the second-in-command of the county's agricultural department, responsible for the cultivation and promotion of improved seed varieties. Of course, her primary responsibility was seed cultivation, while promotion was handled by her.
The actual work was carried out by the personnel who had been working with her in experimental fields across the county for the past two years.
However, they were not working for free. This promotion effort was essentially a "gilding" opportunity. Once the promotion was successful, everyone would receive merit, and they would be promoted by at least half a rank or a full rank.
Starting from the third year, Zhu Yunying began developing methodologies while simultaneously cultivating new improved varieties. This involved applying more advanced agricultural knowledge to seed cultivation and teaching it to the people working with her.
This transformed her from someone who stumbled upon good fortune to someone with genuine skills.
During this process, she did not forget to study, or at least pretend to study diligently, ensuring everyone saw her dedication to work and study day and night. This laid the groundwork for her to present more advanced knowledge in fields other than agriculture in the future, making it seem natural rather than questioning how she could produce advanced medical or other technologies without ever having read books on those subjects.
In the fourth and fifth years, she continued to focus on cultivating improved seed varieties. Using a relatively ingenious method and attributing her success to luck, she cultivated a large number of superior varieties in a very short period. Of course, in her free time, she also pretended to constantly read, improving her knowledge base.
By the sixth year, the initial batch of improved varieties she provided had been widely planted across suitable regions nationwide, achieving an excellent result of doubling the total yield in the planting areas that year. Zhu Yunying not only received the highest award in agronomy but also appeared on national television and major newspapers as an exemplary figure.
Her fictional master was also posthumously honored.
In the seventh year, the superior varieties subsequently cultivated by Zhu Yunying also began to be planted on a large scale, successfully covering areas less suitable for the initial varieties she provided, officially doubling the yield in most of the country's main grain-producing regions.
With the abundance of grain, other industries also saw certain improvements and development, particularly the food industry and animal husbandry. These sectors, unable to develop when food was scarce, could only progress and expand rapidly when food was abundant.
The development of these two industries, in turn, drove the advancement of other sectors, indicating a chain reaction affecting the entire system.
The improvement and progress of a foundational industry would inevitably drive the progress of many other basic industries.
In the eighth year, Zhu Yunying's grandmother passed away from cancer. This provided her with an opportunity to expand her development into other areas. In the same year, she successfully developed drugs to inhibit the development, spread, and deterioration of cancer. Not only did she gain some reputation in the international pharmaceutical industry by publishing numerous papers, but she also successfully industrialized the production of anti-cancer drugs. This brought hope to cancer patients in China and, in turn, helped the country gain another pillar for earning foreign exchange.
In the ninth and tenth years, although Zhu Yunying did not manage to develop a drug that could completely cure cancer, she successively launched more than a dozen drugs for chronic diseases requiring long-term medication. These drugs were more effective than those sold internationally, capable of treating and inhibiting the conditions.
As for the ultimate outcome, within two years, the foreign exchange reserves had increased tenfold, with most of it earned from these drugs. Additionally, through drug licensing, the state successfully acquired industrial equipment and technologies that had previously been unavailable.
Zhu Yunying's importance grew, and her influence both domestically and internationally continued to expand.
By this time, Ding Yun was becoming somewhat anxious. Coupled with the fact that Zhu Yunying's current influence was not far from the threshold required for imprinting her mark, Ding Yun, in order to quickly conclude this world and return, decided to be more transparent with her again. She stated that she couldn't stay much longer and wanted Zhu Yunying to undertake one last major endeavor to allow her to accrue more merit and fortune before leaving her body.
In return, she would teach her soul-splitting technique.
Furthermore, she would return Zhu Yunying's original body to her, allowing her to move freely between two worlds without restriction, and all the assets accumulated over the years would also be hers.
The prospect of returning to her own body and her own world was an immense temptation for Zhu Yunying.
Therefore, with hardly any hesitation, she agreed to Ding Yun's request.
Then, in the eleventh year since Zhu Yunying's arrival, she announced to the public that she had developed a gene-editing agent capable of treating most incurable diseases, including cancer, and also enhancing physical fitness and extending lifespan.
It was unavoidable. The creation of a medical pod, even with technology sixty years in the future, was not easy, let alone in Zhu Yunying's current era. Moreover, she had no background in bio-mechanical engineering or similar fields, her expertise being solely in the pharmaceutical industry.
Naturally, she couldn't simply replicate the medical pod technology.
Therefore, Ding Yun had to choose another technology with sufficient influence for her. While its configuration would still be somewhat challenging, as long as the secret formula was available, it would be possible to produce a small number, perhaps a dozen or twenty units, with some extra time.
Upon this announcement, Zhu Yunying's influence reached the required level within a few days. As Ding Yun, who had signed a contract with her, she naturally and smoothly imprinted her mark into the world origin of the current world through soul-splitting, completing her objective.
Immediately afterward, Ding Yun withdrew the soul fragment she had entrusted to Zhu Yunying's current body and taught her the soul-splitting technique, helping her regain control of her original physical body.
She also left a considerable amount of knowledge for her.
Simultaneously, she left her memories from the past few years as well, and only then did she feel at ease to withdraw and depart.
