The Pillar of a Great Nation: Every Letter Home She Writes Helps Strengthen the Country

Lin Shanshan transmigrates to 1973, only to find herself from the start abandoned by her family and offered up as a sacrifice to a “cannon fodder regiment commander”!

Bound to the [Military Industry Time Vault], she can retrieve blueprints for advanced equipment from every field, dating from 1950 to 2030!

[Host has extracted a Level 3 blueprint: New Land Mine Fuse. Mental energy consumed: -10!]

[Host has extracted a Level 5 blueprint: Anti-Armor Strike Plan. Constitution penalty: permanent loss of taste!]

A letter she casually sent home leaves the border guards staring in disbelief...

Chief of Staff (slamming the table): You call this doodling for fun? This plan will save three hundred men in the regiment!

The Lin family (regretful): We thought she was expendable. Who knew she'd be the living ancestor holding up the country's borders?

Li Changfeng (eyes red): Honey, stop drawing. If you keep going, I'm afraid I won't be able to protect you.

[System alert: Host is forcibly extracting a Level 8 blueprint. Visual system lock and removal in progress...]

From then on, he became her eyes, and she became his blade!
