In the future after 3000 AD, mankind has experienced a great recession, technological civilization has been completely lost, and society has regressed back to the era of city-states ruled by cold weapons. Due to historical faults, later generations did not know the Qin Emperor and Han Dynasty, and regarded the incomplete prehistoric relics as oracles. The protagonist Shen Mo, as a "time traveler" from the 21st century, arrives in the most barren northern city-state. He awakened the "Database of All Human Historical Facts" and not only knew the military formations of past dynasties, but also mastered the lost farming, metallurgy, and political and economic systems. He started out as a low-level refugee who was regarded as a "madman". He used Shang Yang's reform strategy to strengthen the army, and used Su Qin and Zhang Yi's strategies to control everything. On the battlefield without the smoke of power games and iron-blooded killings, he gradually conquered the descendants of famous generals, ended the troubled times, and established a huge empire that blended the style of the Han and Tang Dynasties with the future order.
