Chen Yuan, a Ph. D. In science, once traveled through Hongwu and Ming Dynasty, and became a declining nobleman with a poor family. He had a title but no rice to cook with. What was even more frightening was that sitting on the dragon throne was the extremely jealous Zhu Yuanzhang!
Facing the surrounding powerful enemies and the decaying court, Chen Yuan silently lit up the technology tree. Making refined salt, modifying gunpowder, building academies... He used knowledge to move the gears of the times, and instantly became a thorn in the side of the imperial power and nobles.
Zhu Yuanzhang loved and hated him at the same time: "This boy's talent is equal to that of a million teachers, but his intelligence is close to that of a demon, so we must guard against it!" When the improved gunpowder showed the power of thunder, the emperor's murderous intention also followed.
In this era of supremacy of imperial power, knowledge is the only weapon. See how Chen Yuan dealt with the relationship between the Hongwu Emperor and the civil and military forces of the Manchu Dynasty. With the Institute of Engineering as the foundation and the ocean fleet as the retreat, he danced a perfect dance of survival on the tip of a knife, and finally built the Ming Dynasty into a science and technology empire where the sun and the moon were the king's territory!
