Modern young man Xiao Xing accidentally traveled to the world of Shunliu in 1943 while playing the mobile game "PlayerUnknown's Battlegrounds". The mobile phone he carried with him became a bridge connecting the two time and space. He discovered that he could enter two rounds of the game at 7 o'clock every night and bring the weapons, equipment, and supplies in the game to the real world. What's even more surprising is that he was able to form a team with his real-life friend Su Yu, thus establishing a link between modern times and the Anti-Japanese War period. With the help of national power, Xiao Xing assisted Chen Dalei, commander of the Sixth Military Region of the New Fourth Army, to develop technology, obtain intelligence, upgrade equipment, and rewrite the historical course of the Anti-Japanese War.
