Traveling back in time as Li Shimin, there are only three years left before the Xuanwu Gate Incident. Facing the pressing brother and the jealous father, the modern soul smiled. This time, Xuanwumen is no longer a battle between trapped beasts, but a modern beheading operation that has been deduced through precise data. Information shielding, psychological tactics, crossfire... History has been completely rewritten under the attack of dimensionality reduction.
The throne is just the starting point. The butterfly wings have flapped, and the world line has completely closed. Eastern Turkic cavalry? It will be the best whetstone for my new army. The overlord of the plateau? It will bear witness to what true destiny is. I want the crowns of all nations illuminated by the sun and moon to be engraved with the same title - Khan of Heaven. History is written by me. This Tang Dynasty should be superior to all other nations!
