When military researcher Lin Yuan was sorting out the historical materials of the Battle of Changping, he accidentally touched an ancient jade, and when he opened his eyes, he was already in Handan City in 260 BC. What was even more frightening was that he discovered that there were only three days left before the tragedy in which 400,000 Zhao soldiers were killed.
Armed with modern military knowledge and an understanding of history, Lin Yuan must convince the stubborn King Zhao and the cautious Lian Po that the Qin army did not retreat, but completed a perfect encirclement of the Zhao army under the command of Bai Qi. However, in this era where outsiders are regarded as spies, every word he says may lead to death.
From court debates to battlefield planning, from cracking the Qin Army's spy network to forming a special reconnaissance team, Lin Yuan struggled in the cracks of history. He must strive for a glimmer of hope for Zhao without changing the general trend of history. But when he successfully rescued 100,000 Zhao soldiers, a more terrifying question emerged: What kind of butterfly effect would this victory bring? And why did the mysterious alchemist who was observing him in the dark call him "Tianji"?
This is a race against time and a game against fate. When modern wisdom encounters ancient machinations, and when personal conscience collides with the torrent of history, how will Lin Yuan rewrite that eternal tragedy without being crushed by history?
