Chen Jinglan, a modern aerospace materials scientist, died suddenly in the laboratory, but traveled through time and became the foolish daughter of a landlord in Peiping in 1937. She woke up prophetically amidst the gunfire at the Marco Polo Bridge, and inherited the mysterious space "Jingzhai" that her family had guarded for hundreds of years - her future research manuscript from 2035 was actually stored in it!
Time travel is not an accident, but a "time and space mission" that she must complete. Facing the broken mountains and rivers, she combined Jingzhai's modern laboratory with her family's huge business network, and in the most difficult early days of the war, she worked hard to turn the tide on the invisible front: upgrading military materials for frontline troops, establishing ghost communications for underground organizations, and secretly transferring key industrial equipment and scientific and technological talents to the rear.
When everyone thought she was the "foolish third lady" of the family, she was already the "Master of Jingzhai" who played chess behind the scenes. And everything she did was not only to win the war, but also to unlock Jingzhai's ultimate authority and uncover the astonishing truth behind this time travel that related to the survival of civilization.
This is a story of knowledge, sacrifice and hidden greatness.
