A modern soul transmigrates into the body of Li Ke, Prince of Wu, son of Emperor Taizong of Tang and grandson of Emperor Yang of Sui. Knowing how politically sensitive his identity is, he asks to be sent to Jiangnan at just ten years old, where he lies low and bides his time.
In the prosperous lands of Wu, he promotes agriculture and sericulture, strengthens commerce and industry, and opens up maritime trade routes. He builds wealth and improves people's lives, earning a reputation as a virtuous prince. In secret, he trains elite troops, studies “natural philosophy” (the rudiments of gunpowder), and builds an intelligence network, quietly amassing strength. He watches the succession battles in Chang'an from the sidelines, keeping a low profile while helping the country through its troubles.
During the Yonghui era, the powerful minister Zhangsun Wuji uses the “Fang Yiai case” to make his move. With his life on the line, Li Ke fights back from the brink, joins forces with others to expose the conspiracy, and ultimately brings Zhangsun down. He returns to the center of power with an overwhelming reputation.
From then on, he advances with careful, calculated steps, curbing Empress Wu's rise until he finally ascends the throne. Once emperor, he launches a sweeping wave of reforms: overhauling institutions and revolutionizing the imperial examinations to break the power of the great clans; recruiting and strengthening the army, secretly developing gunpowder, crushing Goguryeo, subduing Tibet, and securing the Western Regions; promoting commerce and industry, expanding maritime trade, and improving people's lives.
As he dispels the shadow of the An Lushan Rebellion, a stronger, more prosperous, and more open Tang rises under his rule, ushering in a “New Kaiyuan Era” far greater than anything history recorded! See how Li Ke uses modern wisdom to break free of the shackles of his identity, claim the imperial throne, and forge a glorious new Tang dynasty!
It's okay to read it as a novel. Maybe I'm too picky. There are a lot of flaws in the details. It doesn't matter if it's a novel. Unfortunately, I'm used to rigorous reading. I can only say that it's okay, but it can't be taken seriously.
