Lin Chen unexpectedly gains the ability to travel through time, moving between the modern era and the years of the War of Resistance Against Japanese Aggression. He alone can cross between the two eras in the flesh, while his partner, Chen Lie, remains rooted in the old land ravaged by war. Their minds are connected and they share each other's vision, like two sides of the same coin fighting side by side across the long years.
In the modern era, Lin Chen relies on his storage space, discerning eyes for antiques, and secret ancient martial arts manuals to move between the city and enemy territory. He procures medicine, food, weapons, and classified intelligence, continuously sending support to his comrades far away. On the front lines of the war, Chen Lie uses these supplies from across time to rally scattered resistance fighters and establish a foothold in the enemy's rear, building a base from a single spark into a raging blaze. He battles to the death against Japanese blockhouses, encirclement campaigns by special forces, and infiltration plots.
The fates of the two eras are already inextricably linked. Every truckload of supplies and every piece of intelligence Lin Chen takes back could change the course of a battle. The battlefield experience Chen Lie buys with his blood also repeatedly helps Lin Chen in the modern era, allowing him to escape deadly dangers. Through raid after raid, rescue after rescue, and stand after stand, they turn seemingly hopeless situations around, help trapped comrades break out, and rekindle hope in a land torn apart by war.
They guard their homeland through the flames of war, and protect their country across time. This secret relay between two eras is both one man's struggle amid chaos and a pledge of life and death when the nation faces extinction. Thus begins a passionate epic written across two eras.
