Dai Chengguang, a 26-year-old military master, held the Huangpu pocket watch left by his grandfather and traveled through the Yunnan-Burma battlefield in 1942, becoming General Dai Anlan's personal guard. The "bloodline modifier" he activated can turn Japanese military equipment into beautiful weapons in an instant: the Type 38 rifle turned into an engraved M1 Garand, and the Type 97 tank was welded with the "Seagull" logo - the price was that every time it was transformed, the pocket watch chain would break, and he would have a scar in reality.
In the Tonggu trenches, he used modern tactics to lay booby traps, but was deafened for three days due to metal resonance when converting a mortar. The blood-soaked inside of the helmet was forever engraved with the date of sacrifice of the recruit Agui; in the Savage Mountain rainforest, in order to save Xiao Shunzi who was dying of malaria, he activated "causal replacement" to bear the fatal injury for the other party. In severe pain, he saw Xiao Shunzi's younger brother's teacher appointment letter in the modern memorial hall.
Dai Anlan noticed something unusual about him, but silently put the modern pen he picked up into his pocket: "Chengguang, this marksmanship is more like my grandson I have never seen before." When the cracks in the pocket watch spread to the "Huangpu Issue 13" engraving, the system prompted "Time and space correction completed, host's remaining life span is 3 months", he finally understood: he is not a hero who rewrites history, but a messenger for millions of heroes.
Those tanks with "Lao Zhang's Rice Balls" engraved on them, fighter planes sprayed with "Give Me Back My Country", and first aid boxes filled with Xiao Shunzi pencils have become eternal in the long river of time - just like the military order written by the general on the bark of the tree: "Seagulls can cross the sea because there are thousands of lights behind them."
