Military System: I Train Troops to Fight Against Japan in Parallel Time and Space

What if in the desperate situation of the Battle of Songhu, an iron-blooded army suddenly appeared that did not belong to this era? Military fan Lin Feng traveled through time in a dream and activated the super military system! While others fight tooth and nail, I have a mechanical synthesis brigade; while others fight guerrillas, I play rudimentary information warfare. Starting from saving a bloody battle that must be lost, I armed the old mountains and rivers with military concepts that transcended the times. This Dragon Kingdom, it's up to me to awaken its edge in advance! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
