Traveling Through Zhu Di, Hard-Core Science and Technology to Save the Ming Dynasty

In 1382 AD, King Zhu Di of Yan was seriously injured and on the verge of death. Liu Ye, the scientific research soul of the 21st century, suddenly awakened in this body. Before his eyes were two cold death notices: [A year later, the empress Ma died! ] [Ten years later, Prince Zhu Biao died! ] Afterwards, there will be a long night of Jingnan, blood and fire, prosperity and happiness, and even the final overthrow of the empire. No system, no plug-ins. Only the vast knowledge of a modern scientific researcher and a future memory that cannot fail. His mission: to change his destiny! The first step is to use health-preserving methods to race against death and bet on the motherland's chance of survival! The second step is to spend ten years climbing the technology tree with bare hands and use penicillin to revive the big brother! Zhu Yuanzhang thought he was crazy, but Zhu Biao thought he was evil. Only Queen Ma stroked his forehead and sighed with a smile: "My son, there seems to be something different." Saving my mother and saving my brother is by no means the end. His plans are great— If we want this Ming Dynasty, we will never have the shame of hunting in the north! If we want this China, there will never be a disaster like the Five Huns! I want this sea of ​​stars to forever be branded with the name of Yongle. A hard-core time travel relying only on knowledge and will, starting from scratch. The pace may be a little slower, but every step is reshaping history.
