How Did I Become the King of Soldiers When I Was Just a Street Kid?

The frustrated Xu Guang accidentally traveled back to his youth, where he was an out-and-out street kid. This time, he did not choose to fail, but directly joined the army and directly awakened the strongest soldier king system. Since then, the originally useless street kid has transformed into a training devil and an all-powerful god of war. "No, Xu Guang is so good at training. Isn't he afraid of sudden death?" "I would like to call Xu Guang the contemporary sniper god. He can hit the target with 100 shots at 2,500 meters. Is this a human being?" "Xu Guang, please, can you stop being so curled up!" "Our army has Xu Guang, which can be worth ten thousand people!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
