He is a top student in modern national defense technology and is proficient in weapons research and development, material application, and tactical deduction.
When he woke up, he became Xiao Jin, the most unpopular and sickly concubine in the General Palace of Dajing Dynasty.
Twelve years old, frail and sick, his biological mother died young, his brother-in-law bullied him, and his servants looked down upon him. In this troubled world with frequent wars and alien races, he lives on thin ice and may die silently at any time.
But Lin Yan didn't believe in fate.
He used modern medical knowledge to save himself, used engineering mechanics to improve armor, and used chemical principles to develop gunpowder. When everyone thought he was just a sick man, he had quietly established his own military workshop and trained the first battalion of gunfire.
Beidi's cavalry went south, and his three hundred gunmen defeated 20,000 enemy troops;
When the Western Qiang barbarians invaded, he led his army deep into the dangerous situation and killed the Western Qiang king in one battle;
The King of Ningbei supported 200,000 troops to rebel. He defended Tongguan and attacked Beidi's reinforcements in front and back, and the outcome was decided in one battle.
He grew from an unappreciated concubine to the king of Zhenbei with a large number of troops; from a simple military commander to a regent who controlled the overall situation.
But the journey is not over. In the court, the Prime Minister's Mansion is watching; outside the border, forces from all sides are ready to move; in the wider world, there are still unknown challenges waiting.
This is a story about a modern soul struggling to survive in the troubled times of ancient times and changing its fate against the will of heaven. Here there is real technology implementation, cruel war strategies, passionate feelings for family and country, and touching love between children.
When modern technology collides with ancient wisdom, when rational thinking collides with human nature - let's see how Xiao Jin can shape the world and create an unprecedented prosperous age!
