Datang: the Prediction at the Beginning Takes the Blame, I Made the Sun Never Set

Traveling through Zhenguan for four years, I, Li Kuan, was declared by Yuan Tiangang to be a demon star that brought disaster to the country! He returned from the brink of death at the age of ten, only to stay in Chang'an until he was eleven years old, and the Second Emperor of the Tang Dynasty died! Li Shimin issued an imperial edict and exiled me to the barren Li Mountain, leaving me to fend for myself. The civil and military officials of the entire dynasty, the five surnames and the seven nobles all laughed at me for being an abandoned prince who will never be able to stand up again! But they don't know I am Dr. Li Bin, the third-level special operations officer of the Snow Leopard Commando! The special forces training system crushes ancient tactics! Modern battlefield medicine brings back the dead! Standardized gunpowder, firearms and artillery swept across all enemies! Build a military academy, open a new school, and break the monopoly of aristocratic families! The barren Lishan Mountain was built by me into the first Longxing Holy Land in the Tang Dynasty! From then on, culture suppressed the aristocratic family and martial arts conquered the frontier! Help Li Shimin sweep through the eight wastelands and create the only Tang Dynasty empire on which the sun never sets!
