Two lines of time and space: AD 616 (the twelfth year of the Great Cause) and AD 2616. In the future, China will be crushed by high-dimensional civilization, and the ceiling of civilization will be locked. Think tank deductions found that the prosperity and rapid demise of the Sui Dynasty was the historical node of the Chinese civilization. Due to the internal strife of the late Sui Dynasty, the gene pool of later generations declined, interrupting the rise of China's national destiny.
Yang Guang, the subjugated tyrant who had rebelled against everyone in the world, faced the pressure of the Guanlong clan and Li Tang's opportunistic usurpation. With the help of 36 descendants of China who shed blood and sacrificed their lives, he changed his destiny against the will of heaven, recast the Sui Dynasty, and raised the eternal upper limit of Chinese civilization genes.
The time travelers are all top leaders in various modern fields (geostrategists, agricultural construction experts, military industry, finance, espionage, etc.), And no one is omnipotent. They have no self-interest, no longevity, no glory, they just want to use 30 days of their lives to carve the drawings and ideas into Yang Guang's mind, and then die with a smile. From then on, Yang Guang drew his sword to the sky, slaughtered all the noble families, cut off the Li Tang Tiantuan, changed his destiny in the name of a tyrant, and rebuilt China's eternal history!
